1. Field
The methods and systems disclosed herein relate to real time communication connections and advertising in general and performance-based advertising in particular.
2. General Background
Telephone systems allow users to conduct real time two-way voice communication. Traditional landline based telephone systems connect one telephone set to another through one or more switching centers, operated by one or more telephone companies, over a landline based telephone network. Traditionally, a telephone connection is based on a circuit switched network.
Current telephone systems may also use a packet switched network for a telephone connection. A packet switched network is typical in a computer data environment. Recent developments in the field of Voice over Internet Protocol (VoIP) allow the delivery of voice information using the Internet Protocol (IP), in which voice information is packaged in a digital form in discrete packets rather than in the traditional circuit-committed protocols of the public switched telephone network (PSTN).
Cellular networks allow a cellular phone to connect to a nearby cellular base station through an air interface for wireless access to a telephone network. Recent developments in wireless telephone systems allow not only voice communications but also data communications. For example, cellular phones can now receive and send short messages through a Short Message Service (SMS). Web pages can now be retrieved through wireless cellular links and displayed on cellular phones. Wireless Application Protocol (WAP) has been developed to overcome the constraints of relatively slow and intermittent nature of wireless links to access information similar or identical to World Wide Web.
Telephone companies provide a number of convenient features, such as call forwarding. Call forwarding of a telephone system allows a user of a phone at a given phone number to dial a specific sequence on the phone to cause the telephone system to forward incoming calls addressed to the phone number to another specified phone number indicated by the dialed sequence.
Telephone systems are frequently used in conducting business. Telephone numbers are typically provided in advertisements, web sites, directories, etc., as a type of contact information to reach businesses, experts, persons, etc.
The Internet is becoming an advertisement media to reach globally populated web users. Advertisements can be included in a web page that is frequently visited by web users. Typically, the advertisements included in the web pages contain only a limited amount of information (e.g., a small paragraph, an icon, etc.). The advertisements contain links to the web sites that provide further detailed information. In certain arrangements, the advertisers pay the advertisements based on the number of visits directed to their web sites by the links of the advertisements.
Performance based advertising generally refers to a type of advertising in which an advertiser pays only for a measurable event that is a direct result of an advertisement being viewed by a consumer. For example, paid inclusion advertising is a form of performance-based search advertising. With paid inclusion advertising, an advertisement is included within a search result page of a key word search. Each selection (“click”) of the advertisement from the results page is the measurable event for which the advertiser pays. In other words, payment by the advertiser is on a per click basis.
Another form of performance-based advertising includes paid placement advertising. Paid placement advertising is similar to paid inclusion advertising in that payment is on a per click basis. However, with paid placement advertising an advertiser ranks a particular advertisement so that the advertisement appears or is placed at a particular spot, e.g., at the top of a search engine result page, thereby to increase the odds of the advertisement being selected.
Both forms of performance-based advertising, i.e., paid placement and paid inclusion, suffer from the limitation that an advertiser or participant within a paid placement or paid inclusion advertising program is required to have a web presence, in the form of a web page.
In one aspect, a method includes receiving a text for a first advertisement presentable in a first media type, and converting the text into an abbreviated text for a second advertisement presentable in a second media type. Furthermore, the abbreviated text can be converted into an audio advertisement.
In another aspect, in response to a request received from an advertiser, an audio advertisement is generated based on visual advertisement information. The audio advertisement is provided for representation on behalf of the advertiser. A determination is made as to whether a call from a customer has been connected to the advertiser via the audio advertisement. The advertiser is charged a predefined fee if it is determined that a call from a customer has been connected to the advertiser via the audio advertisement.
In one embodiment, a determination as to whether a call from a customer has been connected to the advertiser via the audio advertisement can be made by performing additional operations. In one example, a call is received from the customer, and information related to the call from the customer is recorded in order to calculate the predetermined fee. The call can be forwarded to the advertiser. Alternatively, a separate connection can be made to the advertiser; and then the phone connections can be joined to connect the customer and the advertiser.
In one embodiment, the visual advertisement information includes text. The visual advertisement can also include an image.
In one embodiment, the audio advertisement can be provided to the customer during a directory assistance call. The directory assistance call received from the customer can be forwarded to the advertiser, or forwarded to the telephone number that can be used to reach the advertiser. Alternatively, the telephone number that can be used to reach the advertiser and to track the call activities to the advertiser is provided to the customer during the directory assistance call, via the audio advertisement, to allow the customer to dial a call separate from the directory assistance call. In one embodiment, the telephone number provided during the directory assistance call is also usable to identify that the telephone number is provided via the audio advertisement; and when the telephone number is called to reach the advertiser, the provider of the directory assistance service can be credited for delivering the audio advertisement to the customer.
In one embodiment, at least a portion of the content of the visual advertisement can be converted into the audio advertisement by summarizing the text of the visual advertisement. For example, the summarization can be performed by extracting words from the visual advertisement information into a summarized text for advertisement. In addition, the summarized text can be converted for advertisement into speech that conveys an audio advertisement message.
In one aspect, a system includes an advertisement creation module, an advertisement publication module, and a call handling module. The advertisement creation module is to generate an audio advertisement based on visual advertisement information in response to a request from an advertiser. The advertisement publication module is to provide the audio advertisement for presentation on behalf of the advertiser. The call handling module is to determine whether a call from a customer has been connected to the advertiser via the audio advertisement, where the advertiser is to be charged a predefined fee if it is determined that a call from a customer has been connected to the advertiser via the audio advertisement.
In one aspect, in response to a request received from an advertiser, a portion of a content of the advertisement is converted into an abbreviated advertisement. The abbreviated advertisement is provided to a customer of the advertiser. A determination is made as to whether a call from the customer has been connected to the advertiser via the abbreviated advertisement. The advertiser is charged a predefined fee if it is determined that a call from the customer has been connected to the advertiser via the abbreviated advertisement. Alternatively, an unabbreviated audio advertisement can be created from a text advertisement. For example, an audio can be created directly and verbatim from what the advertisers (or agent/advertisement creator) created in textual form.
By way of example, reference can now be made to the accompanying drawings.
The method and system described herein permit an advertiser to deliver advertisements through one or more communications media and pay according to calls received from customers. Thus, advertisers that either (a) do not have web pages, or (b) have web pages that are not effective at capturing the value of a web visitor, and are therefore unable or unwilling to participate in the traditional performance-based advertising as described above, can use the methods and systems according to embodiments of the present invention.
A “pay-per-call” scheme is provided herein, in order to provide advertisers an opportunity to advertise and pay for the advertisement when a customer calls as a response to a delivered or published advertisement. Advertisements can be delivered through computer networks, or telephone networks, or in combination. In addition, advertisements can be in a plurality of formats. For example, an advertiser can establish a campaign of one or more of an audio advertisement, short message advertisement, image advertisement, multimedia advertisement (e.g., via interactive TV), etc. Various techniques are explained herein to deliver advertisements through one or more communication media. In addition, various techniques can be utilized to generate or convert advertisements to audio, short text message, or multimedia format. For example, text-to-speech techniques can be utilized. In another example, text summarization techniques can be utilized.
Although
The real time communication may be on a one-to-one basis (e.g., one caller connected to one callee). The real time communication can also be in the form of one-to-many. Further, in one embodiment, the real time communication may include access to recorded sessions (e.g., recorded audio content and/or recorded video content).
In one embodiment, the computer network 104 is the Internet. In another embodiment, the computer network 104 is an intranet. The advertisement processing service 112 can be one or more entities that receive requests from advertiser 108 for processing advertisements, for converting text advertisements to a short text message advertisement, for converting text advertisements to voice or audio advertisement, etc. In one embodiment, a text suitable for presentation as an advertisement in a visual form, such as in a search result of a web page, is converted to an abbreviated form suitable for presentation on a media channel that has a limit on the length of the advertisement. For example, to be effective, an audio advertisement presented during a directory assistance call is preferably limited in length. Typical text advertisements generated for presentation on a web page can be have a length longer than a preferred limit for audio advertisements. In one embodiment, the advertisement processing service 112 provides a service to shorten the text advertisement to generate a corresponding audio advertisement for the advertiser. In one example, the advertiser 108 can communicate through a website hosted by the advertisement processing service 112 and submit a request for a creation of an advertisement, conversion of an advertisement or publication of an advertisement, etc.
In one embodiment, the advertisement processing service can also track calls that are made to the advertiser 108 in accordance to the pay-per-call business scheme. In addition, the advertisement processing service 112 can communicate with an advertisement delivery service 110.
The advertisement delivery service 110 can be a search engine that posts advertisements that have been processed by the advertisement processing service 112. In another example, the advertisement delivery service 110 can be a bulletin board company that posts advertisements processed by the advertisement processing service 112. In yet another embodiment, the advertisement delivery service 110 can be a directory assistance service that delivers advertisements to a customer who calls to make a directory assistance request (e.g. 411 services).
The advertisement processing service 112 can submit preprocessed advertisements in the form of text or audio to the advertisement delivery service 110. The advertisement delivery service 110 can deliver the advertisements to customers at suitable times and places. If the advertisement delivery service 110 is a directory assistance company, the advertisement can be delivered through the telephone network 102. Then, the advertisement can be presented to the customer 106 during the directory assistance call.
In another example, if the advertisement delivery service 110 is a search engine or any other website that includes pop-up advertisements, banner advertisements or any other form of advertisement on the worldwide web, the advertisement delivery service can communicate through computer network 104 with customer 106. Customer 106 can receive the advertisement on a personal computing device. Once the advertisement has been delivered or published, the customer can select to be connected to the advertiser 108 through the telephone network 102 or internet. Alternatively, once the advertisement has been published on a website or any other visual medium, the customer 106 can dial an advertised telephone number to request a phone connection to the advertiser 108. When the advertised telephone number is dialed, the call is connected to the advertisement processing service 112, enabling the advertisement processing service 112 to track the calls made to the advertiser 108 via the advertised telephone number. The advertisement processing service 112 may forward the call to the advertiser, or make a separate connection to the advertiser and then join/conference the advertiser and the customer.
In one embodiment, the customer 106 is presented with a telephone number that has been associated to advertiser 108. The telephone number can be a number generated by the advertisement processing service and assigned to the advertiser. In addition, the telephone number can be for the advertisement processing service 112 such that calls to the generated telephone number are routed to the advertisement processing service 112. The advertisement processing service 112 upon receiving the call from the customer can search and match the telephone number received or dialed from the customer and match the telephone number against the advertiser's 108 telephone number. The advertisement processing service can then forward the call to the advertiser 108 and simultaneously track that a call has been received from customer 106 for advertiser 108.
In another embodiment, the advertisement delivery service 112 is configured to receive the call directed to advertiser 108 from customer 106. For example, if the advertisement delivery service is a directory assistance service, upon presenting an audio advertisement to the customer 106 during the directory assistance call, the advertisement delivery service 110 can re-route the call to advertiser 108 if the customer 106 approves of such forwarding. If the call is forwarded to advertiser 108 (e.g., according to the record of the directory assistance service), advertiser 108 is charged a pre-determined amount. In another example, the call is not forwarded to advertiser 108, but the advertisement is presented to customer 106 together with the phone number that is assigned by the advertisement processing service 112 to the advertiser; thus, when the assigned phone number is dialed, the advertisement processing service 112 can track the call and charge the advertiser a pre-determined amount (e.g., according to a pay per call price bid specified by the advertiser). In a further example, the call is forwarded to the advertisement processing service 112 at the phone number assigned to the advertiser; the advertisement processing service 112 further connects the call to the advertiser based on the association between the assigned phone number and the advertiser; thus, the advertisement processing service 112 can track the calls to the advertiser. In one embodiment, the assigned phone number is also associated with the directory assistance service; thus, when the call is connected to the advertiser via the assigned phone number, the advertisement delivery service 110 may be credited for the call. Alternatively, the advertisement processing service 112 may charge the advertiser on a pay per call basis, while purchasing advertisement slots from the advertisement delivery service 110 based on a different price model, such as on a monthly fee, a flat fee for each presentation of the advertisement, etc. In one embodiment the advertisement delivery service 110 and the advertisement processing service 112 are part of the same business entity. In another embodiment, the advertisement delivery service 110 is a separate business entity than a business entity that processes advertisements according to advertisement processing service 112.
In one embodiment, the customer 106 requests a telephone connection to the advertiser 108 via a telephone reference, such as a phone number assigned by the advertisement processing service 112 to the advertiser 108. In another embodiment, the customer 106 requests a telephone connection via a non-telephone connection, such as a web connection. For example, a hyperlink can be used to allow the customer to request a telephone connection to the advertiser. When the hyperlink is selected, the telephone number of the customer is further collected in a web page; the telephone number of the advertiser can be looked up based on a parameter embedded in the hyperlink; and then, the advertisement processing service 112 can make separate calls (e.g., initiated via VoIP telephony service provided by a telephone carrier) and then join the calls to connect to the customer and the advertiser. Alternatively, the customer may request the telephone connection via a short text message, an instant message, or via other communication methods.
Thus, an advertiser 108 can submit a string of text by typing the string of text in a field for entering text provided in a web page hosted by the advertisement processing service. The string of text is submitted through the computer network 104 to the advertisement creation and management module 204. Once the string of text is received, the string of text can be processed to include a telephone number assigned to the advertiser 108 and/or other references that can be used to request a telephone connection to the advertiser 108, such as a hyperlink.
In another embodiment, once the string of text is received not only can a telephone number that is assigned to the advertiser 108 be injected into the string of text, but also the string of text can be reduced or summarized into a smaller or shorter text message. A summarization technique based on extraction or abstraction can be used to reduce the length of the text. For example, an extraction method can rank the sentences and selectively extract a set of sentences to generate a shorter version of the text message. An abstraction method parses the text message, interpreting the text, finding concepts to describe the text, and generating a short text to describe the concepts. Summarization can be performed by a data processing system at a reduced cost. Summarization can be also be performed by a human operator with high quality. In one embodiment, summarizations generated by a data processing system are used initially. The machine generated summarizations can be reviewed by the advertisers and/or selectively reviewed by human operators. In one embodiment, different text advertisements are prioritized (e.g., based on the past performance of the advertisements, based on the difficulties the advertisers encountered in accepting the machine generated summarization, etc.); based on the priority ranking the advertisements are selectively reviewed or summarized by human operators.
Therefore, the advertisement creation and management module 204 can be configured to carry out summarization of text. In another embodiment, the creation and management module 204 can be configured to provide operations and functions to a user who performs the summarization of the text.
In addition, the advertisement creation and management module 204 can also be configured to convert from text to an audio format (e.g., in speech recognizable to a human). The advertisement creation and management module 204 can utilize text to speech conversion techniques and methods known in the art to extract relevant words from the string of text in order to produce the audio advertisement.
Alternatively, the advertisement creation and management module 204 can also be configured to assist a user or operator to create an audio advertisement by providing recording and sound editing functions.
In one embodiment, the advertisement creation and management module 204 can further communicate and interact with a web server coupled to the advertisement creation and management module 204 to transmit and receive messages from the advertiser 108 through computer network 104. Thus, for example, advertiser 108 can utilize a computing device such as a personal computer, a portable computing device, etc. to interface with a web application and submit edits, delete commands or change advertisement campaign preferences. For example, the advertiser 108 may be able to indicate the time in which a certain advertisement should be published or delivered.
An advertisement publication module 202 can be utilized for publishing and delivering the advertisement or advertisements of an advertiser 108 to a customer 106. The advertisement publication module 202 can be configured to interact with the advertisement creation and management module 204 to receive advertisements that are to be delivered or published or presented to a customer. In one embodiment, the advertisement creation and management module 204 transmits the advertisements through computer network 104 to the advertisement publication module 202. Any other forms of transmission can be utilized to convey the advertisements to be published by the advertisement publication module 202. The advertisement publication module 202 can be part of the advertisement delivery service 110 discussed in the description of
The advertisement publication module 304 can be configured to assist a directory assistance infrastructure in order to provide advertisements during a directory assistance call. As such, the advertisements provided to directory assistance callers can be injected during a call with a customer calling from customer telephonic device 310. The customer telephonic device 310 can be a rotary dial telephone, cellular phone, a digital phone or a telephonic device integrated in a personal computer such as a desktop or a laptop or a personal data assistant (PDA), a smart phone, a cellular phone, a tablet PC or any other computer device they can have a telephonic device embedded therein. The advertisement publication module 304 can include logic to receive the advertisement from the advertisement creation and management module 204 and submit audio, video, text or image advertisements to the advertisement publication module 304. As such, the advertisement publication module 304 can be a component of the infrastructure of an advertisement delivery service 110. For example, the advertisement publication module 304 can be a component of an infrastructure of a directory assistance service.
In another example, the advertisement publication module 304 can be a component of a broadcast delivery system that can communicate an audio advertisement through a telephone network 102. Yet another embodiment, the advertisement publication module 304 can be part of a telemarketing entity that delivers audio advertisement through the telephone network 102 to one or more customers. Finally, the advertisement publication module 304 can be a component of an infrastructure of a demand partner of the advertisement processing service 112. A demand partner can be any advertisement delivery service that can deliver audio telephonic advertisements through the telephone network 102.
In one embodiment, the advertisements for an advertiser are provided to customers through different advertisements publication modules, via different communication media, such as web, instant messaging, short text message, interactive TV, internet TV, telephone, newspaper, magazine, radio, etc. An advertisement specified by an advertiser (e.g., in text via a web interface) can be used to generate different types of advertisements that are suitable for the presentation on different media channels. In one embodiment, the advertisement information supplied by the advertiser is abbreviated to generate an advertisement suitable for the advertisement distribution media. In one embodiment, the advertisements are presented on various media channels on behalf of an advertiser; and the advertiser is charged based on a price the advertiser bid for each telephone lead generated from the advertisements, regardless of the media channels used to generate the telephone lead. In one embodiment, the media channels that are responsible for generating the telephone leads are separately tracked; and the tracked information can be used to distribute revenue generated from the advertising and/or to improve the allocation of advertisements in different media channels.
In another embodiment, the audio generation logic 508 can create an audio advertisement based on any other input received from the advertiser 108 (e.g., checkboxes, coupon expiration date selection dropdowns, etc.). The advertisement audio generation logic 508 can also be configured with sound editing and production functions and operations in order to assist a user or operator to create an audio advertisement. For example, the advertisement audio generation logic 508 can be configured to provide recording functions such that the operator can record the audio advertisement.
In another embodiment, the advertisement audio generation logic 508 can be configured to allow the operator to select pre-recorded words to construct the audio recording. In another embodiment, the advertisement audio generation logic 508 can be configured to construct the audio advertisement by selecting pre-recorded words corresponding to words in a text advertisement. The words in the text advertisement can be obtained, in one example, from the text generation logic 512.
In yet another embodiment, the advertisement audio generation logic 508 can be configured to construct the audio advertisement by selecting pre-recorded words corresponding to words in an abbreviated text advertisement. The abbreviated text advertisement can be generated by a text summarization logic 510 discussed below.
The text generation logic 512 can also be included as part of the advertisement creation module 504. The text generation logic can permit an advertiser to input a text string. In one example, an advertiser can include text such as “Burt's Plumbing now offered in San Francisco—Check Out Our Special Deals.” This text can be included in the advertisement when the advertisement is rendered and published for customer viewing.
The text summarization logic 510 can also be included as part of the advertisement creation module 504. Text summarization logic 510 can be configured to receive text as input and summarize the text by extracting key words that best represent the business, the type of services or any other words that the advertiser wants to stress.
Thus, text summarization logic 510 can include logic that extracts words in the language (e.g., English) that are most relevant and that are not connecting words, such as articles, but rather are words that convey meaning. For example, the text string “Burt's Plumbing now offered in San Francisco—Check Out Our Special Deals” can be summarized as “Burt's Plumbing in San Francisco, Special Deals.”
In another example, the text summarization logic 510 can be configured to select relevant words and link the selected relevant words utilizing natural language processing algorithms that follow grammatical rules. For example, artificial intelligence techniques that manipulate language to render grammatically correct abbreviated sentences can be utilized. In addition, any heuristic model can be utilized. In one example, short sentences can be derived from a database of advertisement sales pitches. In another example, short sentences can be derived from a database of commonly used words in advertisement.
In one embodiment, once the text summarization logic 510 generates abbreviated text, the abbreviated text can be submitted to a quality check operator that reviews the generated abbreviated text for grammatical structure, semantic clarity, etc., such that the abbreviated text is both correct and persuasive. Alternatively, the abbreviated text can be presented to the advertiser for review. The machine generated summarization can be provided to the advertiser in response to input received from the advertiser without an extended waiting period. Thus, the machine generated summarization can be provided to the advertiser as a suggestion to generate an abbreviated version of the advertisement. The suggestion can be further modified by the advertiser and/or later reviewed by a human operator.
In yet another embodiment, the text summarization logic 510 provides functions and operations to an operator who performs the summarization. As such, the summarization of the text can be entirely performed by a human operator.
The advertisement creation module 504 can also include a key word association logic 514 that allows an advertiser to input certain key words which can be associated to the advertisement of the advertiser 108. The key words can, for example, be used for text summarization 510 or can also be used to provide the search engine in a web site of the advertisement publication module 202 such that customers can easily access and be presented with advertisements pertaining to advertiser 108.
Furthermore, a location determination logic 516 can also be provided with, or as part of, advertising creation module 504. The location determination logic 516 permits an advertiser that is not a national enterprise or a national operation such that advertisements are tailored to customers within a certain geographic area. As such, the location determination logic 516 permits an advertiser to select a particular geographic region, such as a state, city or a zip code area of interest, so that the advertiser 108 will have contacts from customers that are relevant in originating only from the area in which the advertiser 108 is located.
Furthermore, the advertisement creation module 504 can also include a telephone number auto generation logic 518 that automatically generates a unique telephone number. The telephone numbers can be SIP numbers for VoIP bases telephony, standard POTS (Plain Old Telephone Serivce) numbers with extensions, click-to-call references, etc. The unique number can further be mapped to the advertiser 108 such that when the unique number is called, the advertiser's 108 phone rings. In one embodiment, the standard POTS telephone numbers without extensions can also be assigned/mapped to advertisers/advertisements. In one embodiment, the telephone number that is automatically assigned can be a toll free number. In another embodiment, the telephone number can be a local number with the same area code of the advertiser 108 or the customer. In yet another embodiment, the telephone number can be an easily recognizable 800 number modified by a unique extension that is mapped to the advertiser 108. For example, the unique extension can be a word that expresses the type of service that the advertiser 108 provides. In one embodiment, the audio generation logic 508 can create and generate a speech or audio version of the telephone number such that an audio version of the telephone number can be used in conjunction or embedded in the audio advertisement created by the audio generation logic 508. Thus, in one embodiment, the advertisement creation module 504 automatically inserts the unique telephone number assigned to the advertiser 108 into an advertisement of the advertiser 108.
In another embodiment, the advertisement creation module 504 can be configured to create an advertisement that is in audio recognizable by a human being and that includes the telephone number of the advertiser 108. In addition, a click to call module 520 can be provided such that when invoked, the telephone number assigned to the advertiser 108 (or the advertisement) can automatically be called when the customer pushes a button. In one example, the button can be provided in a web page of an advertisement delivery service 110 or a web link of the advertisement delivery service 110.
In another embodiment, the button can be provided in connection with the telephonic device 310 of the customer such that the customer is prompted to input a key in the telephone keypad in order to be connected with the advertiser 108. For example, upon listening to the advertisement on the telephone, the customer can be prompted to “Press 1” if the customer 106 desires to be connected to the advertiser 108 automatically.
The advertisement creation module 504 can further include turn on/turn off logic 522 that allows an advertiser to turn off the injection of an advertisement or turn on the injection of an advertisement during a specific period. When an advertisement is turned off or flagged as inactive, the advertisement is considered withdrawn from an advertisement campaign. The advertiser 108 can turn on the advertisement again by flagging the advertisement as active. Only advertisements that are turned on or that have a status of active are published and delivered to customers according to the techniques disclosed herein.
The advertising creation module 504 can also include a smart connect logic 524. For example, the advertiser 108 can have a primary telephone number and one or more secondary telephone numbers associated with an advertisement. In one example, the smart connect logic 524 can first route the customer's call to the advertiser's primary telephone number. If no connection is achieved, then the list of secondary telephone numbers can be used by the smart connect logic 524 to connect to any one of the list of the secondary telephone numbers until a connection is achieved.
The advertisement creation module 504 can also include arrange a call logic 526. The arrange a call logic 526 permits a customer to input a time at which the customer wishes to speak with the advertiser 108. The advertiser can then be contacted to give the advertiser 108 an indication of the arranged call. The advertiser can be contacted in a variety of ways, including fax, mail, e-mail, telephone or any other communication means.
The advertisement creation and management module 500 can also include a payment specification module 506. The payment specification module 506 can be configured with flat fee logic 528, bid for placement logic 530 and spending level logic 532.
The payment specification module 506 can be configured by an advertiser 108 according to one or more parameters set by the advertiser 108. The flat fee logic 528 permits an advertiser to select flat fee billing for each telephone call received by a customer. Therefore, a flat fee can be applied for advertisements within a particular category. In another example, a flat fee basis can be applied for advertisements that are delivered within a certain period of time. In addition, a bid for placement logic 530 can allow an advertiser 108 to choose to be billed on a bid for placement basis. As such, the bid for placement logic 530 can support proxy bids and maximum/minimum bids. In one embodiment, a maximum bid can be specified; and the system automatically determines the lowest bid amount that is no more than the maximum bid and that is above bids from competitors.
The payroll specification module 506 can also include a spending level logic 532 that allows an advertiser to specify daily, weekly or monthly spending levels. As such, the specified spending level can be used by an advertiser to define a budget for a time period that advertiser 108 is willing to pay as a maximum. Therefore, an advertiser 108 can set a budget not to be exceeded within a time period and thereby better manage financial expenditures for advertising campaigns. In one embodiment, if the budget is exceeded within a particular time period, the advertisements or the flagged advertisement can be automatically turned off for the remainder of the time period. The advertiser 108 can further be notified that the spending level limit has been reached and be provided with an option to reactivate the advertisement or advertisements that have been deactivated.
In another embodiment, the payment specification module 506 can include logic to automatically waive charges for follow on calls. For example, if a customer calls on one day, and then later dials the same number to follow up on a call on the same day, the payment specification module 506 can be configured with logic to automatically waive the charge for the second call, since the second call has been already paid for.
At process block 604, the text advertisement is summarized into a short message advertisement. As previously mentioned, the text can be summarized into a short message advertisement by utilizing one or more known methodologies. For example, the text advertisement can be analyzed and meaningful words can be extracted from the text advertisement to form the short message advertisement. The meaningful words extracted from the text advertisement can be representative of the essence of the message that is intended to be advertised to a customer by the text advertisement.
Various summarization techniques can be utilized. In one example, relevant words can be selected from a text advertisement utilizing natural language processing algorithms that follow grammatical rules. In one example, short phrases or sentences can be obtained from a database of advertisement sales pitches. In another example, short phrases or sentences can be derived from a database of commonly used words in advertisement. In another example, summarized text can further be checked for quality by a quality check operator that reviews the generated abbreviated text for grammatical structure, semantic clarity, etc., such that the abbreviated text is both correct and persuasive. In yet another embodiment, an operator can manually summarize the text. The process 600 continues to process block 606.
In one embodiment, the abbreviated version of the advertisement is not only based on the text advertisement, but also based on other information related to or supplied from the advertiser. For example, web pages of the advertiser, comments of the advertiser for the abbreviated audio version of the advertisement, profile maintained by the system, history of the advertisements of the advertiser, etc., can also be considered in the generation of the abbreviated version of the advertisement.
At process block 606, the short message advertisement is submitted to the advertiser for approval. In one embodiment, the short message advertisement can be submitted to the advertiser through a computer network 104. For example, the short message advertisement can be submitted in an e-mail sent to the advertiser 108 for approval. In another embodiment, the short message advertisement is submitted for approval through a public telephone network and received by the advertiser 108 for approval. The process 600 continues to process block 608.
At process block 608, the short message advertisement can be published if the advertiser 108 has approved the short message advertisement. The advertiser can approve by acknowledging the submission of the short message advertisement and by transmitting a similar communication as the one received by the advertiser 108. In another embodiment, the advertiser can utilize any other communications media to communicate the advertiser's 108 approval or disapproval of the short message advertisement. The short message advertisement can be then published in one or more media as discussed above. For example, the short message advertisement can be published on a web page by a web server or by a wireless application server. In another embodiment, the short message advertisement can be published by a short messaging service center through a short message service format. Alternatively, the format can be a multi-media messaging service. In one embodiment, advertisements generated for presentation over different media channels are customized according to the characteristics of the corresponding media channels.
The process 700 continues to process block 704. At process block 704, the text advertisement is converted to an audio advertisement. The conversion logic can be one or more methodologies known in the art for converting text to speech. In one example, the converting logic can utilize summarization algorithms to extract meaningful words from the text advertisement and convert the words extracted from the text advertisement to speech. The converted words can then be concatenated into a single audio message that comprises the audio advertisement. In one embodiment, the generated audio advertisement is customized for an audio channel to have content that is less than and/or different from that of the text advertisement.
In another embodiment, the content of a visual advertisement can be converted into an audio advertisement. The conversion to audio can be performed utilizing various techniques. In one embodiment, the conversion is performed programmatically through a computer process that maps each word in the text advertisement and concatenates the spoken words into an audio message.
In yet another embodiment, the conversion is performed manually by an audio recording operator that receives the text from the advertiser 108 and records an audio advertisement. Having an audio recording operator can provide human input such that the audio advertisement is produced with a certainty that the audio advertisement will be understandable to customers. Human input can also provide the opportunity to create advertisement that is more compelling to customers.
Furthermore, text of the visual advertisement can be summarized by extracting meaningful words from the visual advertisement into a summarized text for advertisement. The summarized text for advertisement can then be converted into natural speech that conveys an audio advertisement message.
The advertisement text can be summarized such that relevant words in the advertisement text, or words similar to the relevant or operating words, are extracted and utilized for building the summarized text. Natural language processing algorithms that follow grammatical rules can be utilized to build the summarized text. For example, artificial intelligence techniques that manipulate language to render grammatically correct abbreviated sentences can be utilized. In addition, any heuristic model can be utilized. In another embodiment the conversion is performed programmatically through a computer process that can process natural language in order to replace one or more words with a shorter word or less number of words. For example, the computer process can be configured to receive the text “Contact our toll-free number” and replace that text with “Call” such that the advertisement “Contact our toll-free number 1-800-SERVICE” is summarized into “Call 1-800-SERVICE.”
In another example, summarization is processed by a computer program and is manually checked by a human operator for grammatical structure, semantic clarity, etc., such that the abbreviated text is both correct and persuasive.
The process 700 continues to process block 706. At process block 706, the audio advertisement is submitted to the advertiser for approval. The audio advertisement can be submitted through the computer network 104 via e-mail or via any other TCP/IP network communication protocols, etc. In one embodiment, the advertiser can manage the advertisements over a web interface; and when available the audio advertisement can be download by the advertiser via the web interface for review and approval.
In one embodiment, once an advertiser 108 receives an advertisement for approval, the advertiser can be permitted to edit the advertisement and resubmit.
In another example, an advertiser 108 can be provided access to create multiple versions of an advertisement. In a further example, as part of advertisement editing, the advertiser 108 may be assisted by a customer service representative that interacts with the advertiser to further refine an advertisement. Preferably, the customer service representative can be a person with knowledge of summarization techniques, etc. The process 700 continues to process block 708.
Note that 706 can be optional. For example, in one embodiment, the advertiser may have approved it up front so that no further approval is needed. In one embodiment, the advertiser can reject or stop the automatically approved advertisement without having to explicitly approve the advertisement before the deployment of the advertisement.
At process block 708, the audio advertisement is published once the advertiser 108 approves. In one embodiment, the advertiser 108 approves the audio advertisement by listening to the audio advertisement at a customer computing device 210 equipped to output audio.
In addition, the user interface 800 can provide a text field 804 such that the advertiser 108 can enter text into text field 804, which is to be converted into audio, or to provide comments or suggestions that are to be considered in the generation of the audio advertisement. Alternatively, the user interface 800 can also provide a drop down menu 806 that lists all the previously submitted text advertisements submitted by an advertiser 108 such that when selected, one of the menu items of the drop down box 806, the selected item, can be converted to, or used in a conversion to, an audio advertisement.
In another example, a browse option 808 can be provided such that the advertiser 108 can upload an advertisement that the advertiser 108 wants to convert to an audio advertisement. Thus, the advertiser 108 can provide an image, a video and audio file, text file, or any other recognizable file format that can then be processed by the advertisement creation and management module 204 in order to create the audio advertisement. In addition, operators and computer software engineers and managers can be utilized by the advertisement processing service 112 to process the file submitted by the advertiser 108 and convert the file or the information in the file into an audio advertisement.
In addition, a notification input 810 can be provided as part of the user interface 800. The notification input can be a check box, a radio button, a drop down menu, a single button, or any other input that can be utilized by the advertiser to select that a notification be sent to the advertiser for approval. If the notification input 810 is selected by the advertiser 108, the advertiser 108 will be notified (e.g., via email, telephone, instant messaging, short text message, etc.) when the audio advertisement is ready for review and approval by the advertiser 108.
In addition, a payment input 904 can be provided in the user interface 900 for providing payment options. For example, payment options acceptable to the advertiser for services and goods can be specified.
The advertisement rendering engine 1002 can be configured to automatically render the advertiser's advertisement through a particular channel. In one embodiment, the advertisement rendering engine can be associated with a campaign management interface displayed to an advertiser 108; and the campaign management interface can be used to receive the advertiser input related to the types of media channels utilized to deliver the advertisements of the advertiser 108.
A price per call logic 1008 can be included as part of the advertisement rendering engine 1002. The price per call logic 1008 permits an advertiser 108 to bid for advertisement prices such that the higher the price of the advertisement, the more visibility the advertisement will have, and further, the lower the price per call of the advertisement, the less visibility that the advertisement will have. This provides an advertiser 108 the flexibility of configuring the visibility of advertisements depending on the interest that the advertiser 108 wants to obtain in specific products or services that the advertiser 108 offers.
In one example, the advertiser can bid for a $3.00 advertisement such that if a customer calls the number indicated in the advertisement, the advertiser will be charged $3.00 for the customer's call. However, the advertiser can increase the visibility of the same advertisement by bidding to pay $5.00 for each customer that calls the number associated with that advertisement. In addition, where one or more advertisers compete for a specific spot for advertisement delivery, the higher bidding advertiser will win and have the advertisement delivered to the customer prevailing over the other advertisers. Thus, for example, if three advertisers are competing for a space on an Internet web site and the three advertisements are appropriate to be placed in such Internet web site according to the content of the web site, or as the result of a search or request by phone etc., the highest bid advertiser will be the winner. Thus, the advertisement corresponding to such advertiser will be placed in the available space in the web site.
The advertisement rendering engine 1002 further includes an activity history logic 1010 that analyzes the number of calls that an advertiser 108 has received during a time period. For example, the number of calls during a specific day can be analyzed and be provided to the advertiser 108. In another example, the number of calls received during a month can be provided to the advertiser 108. In addition, the number of calls for a specific advertisement in relation to a specific period can also be provided.
Furthermore, advertisement status logic 1012 can be provided as part of an advertisement rendering engine 1002. The advertisement status 1012 logic can permit an advertiser to examine the status of a specific advertisement and bid for delivery during specific times. The connection success rate 1014 can be configured to measure the connection success rate for calls to the telephone number assigned to the advertiser 108 for a specific advertisement. The connection success logic 1014 can further rank advertisements of the advertiser 108 within a display page based on the connection success rate.
In one embodiment, the conversion rate (e.g., the rate of calls received via an advertisement to presentations of the advertisement) is estimated or determined for the ranking of advertisements in a display page. For example, an advertisement that is displayed 10 times and called 5 times (and generating pay per call charges each time) has a higher conversion rate than an advertisement that is displayed 10 times and called 3 times. In one embodiment, the conversion rate is used to estimate the expected revenue from the presentation of the advertisement. For example, if the advertisement that is called 3 times for every 10 presentations is paying more per call, it might still be ranked higher than the advertisement that is called 3 times for every 10 presentations. For example, if the advertisement that is called 3 times for every 10 presentations and the price per call is $1.00 for this advertisement, it can be expected that a presentation of the advertisement would bring in an income of $0.30 in average. Given equal bid prices the advertisement that has a higher conversion rate can generate from advertisement income. In one embodiment, the expected revenue can further include other types of income generated from the advertisement. For example, if a commission is charged based upon a transaction resulted from the advertisement, the expected commission can also be estimated and used in the determination of the expected revenue for the presentation of the advertisement.
In another embodiment, a manual indexing logic 1014 can be provided as part of the advertisement rendering engine 1002 and permits an operator to manually index or rank advertisements within a specific publication page. The manual indexing 1014 permits an advertiser 108 to have higher and greater control over how advertisements of the advertiser 108 are displayed and delivered to a customer. Alternatively, a random logic 1018 can be utilized by an advertiser to select advertisements that should be delivered randomly and without a particular index or order as the advertisement would under the manual indexing logic 1014.
Furthermore, the advertisement publication module can include a syndication engine 1004 that can be used to syndicate advertisements of the advertiser 108 to a number of third parties that host publication channels selected by the advertiser. In one embodiment, the syndication engine 104 can be configured to syndicate the advertisement to internet search engines and/or internet yellow page. In yet another embodiment, the syndication engine 1004 can syndicate advertisements to online directories and other media. Finally, the syndication engine 1004 can syndicate advertisements to wireless devices and telephone devices as described previously.
The advertisement publication module can also include an audio playback engine 1006 that can be utilized to deliver audio ads. The audio playback engine can include logic to syndicate or stream audio to a computing device or a telephonic device of the customer such that the customer can then receive the audio advertisement via the customer computing device 210. In addition, the audio playback engine 1006 can work and be configured to render an audio advertisement simultaneously with a text advertisement that a syndication engine 1004 is providing. The text syndication engine 1004 can, for example, display on a web page a text or an image advertisement, and in addition, an audio playback of the audio advertisement can be rendered by the audio playback engine 1006 simultaneously.
At process block 1104, the customer request for a directory assistance listing is received via an automated voice recognition system or through a live operator. The process 1100 continues to process block 1106.
At process block 1106, the business type classification of the directory assistance listing requested by the customer is determined. For example, if the customer requests the name of an airline company, the business type can be air transportation services. The process 1100 continues to process block 1108.
At process block 1108, an audio advertisement can be requested from the advertisement processing service 112. The audio advertisement requested can be specified to be within the business type classification previously identified. If the advertisement processing service 112 identifies an audio advertisement within the type of business classification requested, the advertisement processing service can transmit the audio advertisement to the advertisement delivery service 110 to be delivered to the customer because in this example the advertisement delivery service 110 is the directory assistance service. The directory assistance service can query the customer to select whether or not the customer wants to listen to the audio advertisement or not. In one embodiment, the customer may be given the option to listen to the audio and not be charged for the directory assistance call. In one embodiment, the directory assistance call is free to the customer, even if the customer does not choose to listen to audio advertisements. In one embodiment, at least one audio advertisement is presented to the customer to support the directory assistance call service that is free to the customer. For example, after the operator receives the directory assistance request, a short audio advertisement can be played, while the operator is working on the directory assistance request and/or before the operator provides the result.
In another embodiment, the advertisement delivery service 110, such as the directory assistance service, can have a local database of advertisements that can be utilized to deliver to the customer. Upon identifying the business type related to the customer request, the advertisement delivery service 110 retrieves the advertisement from the local database.
In another embodiment, the audio advertisement requested can be based on “switch pitching.” Switch pitching generally refers to suggesting or recommending a supplementary or substitute service or product to the service or product requested by the caller. For example, if the customer requests car rental service, a supplementary service can be hotel services. In another example, if the customer requests a listing for a real estate agent, a supplementary service can be a mortgage company. In another example, if the customer requests a listing for an Italian food restaurant, a substitute service can be another Italian food restaurant or a Greek food restaurant. Thus, switch pitching can be utilized when the audio advertisement presented to the customer corresponds to supplementary or substitute services to those products or services originally requested by the customer. The advertisement can be retrieved from the local database as discussed above or from a database accessible to the advertisement processing service 112. The process 1100 can continue to process block 1110.
At process block 1110, the audio advertisement is provided to the customer. In one embodiment, the advertiser is charged for the advertisement if the customer is connected to the advertiser via the audio advertisement. In one embodiment, the advertiser is charged a price based on a per call price bid specified by the advertiser. The per call price bids from the advertisers can be used to select an advertisement for the customer. Further, the selection can be made based on other information, such as the category of business that the customer is seeking via the directory assistance call, relation to the business that the customer is interested in, budgets of the advertisers, and/or the conversion rate of the advertisement, etc.
The customer can be connected to the advertiser through forwarding or bridging the call (e.g., the directory assistance call during which the advertisement has been delivered to the customer) to the advertiser. For example, the call can be directly forwarded to the advertiser, after the telephone number of the advertiser is determined. Alternatively, a separate call to the advertiser is established; and the call from the customer and the separate call to the advertiser are joined to connected advertiser and the customer. Alternatively, the call can be forwarded to a telephone number that is assigned to the advertiser and used to track the phone connections made to the advertiser via the audio advertisement; and the system that receives the forwarded call can further connect the call to the advertiser (e.g., through forwarding or through making a separate call to the advertiser and then join/conference the calls). Alternatively, a phone number that is assigned to advertiser and that is used to tracked the calls to the advertiser can be provided to the customer via the advertisement, enabling the customer to make a call to the advertiser subsequently, separately from the directory assistance call. Alternatively or in combination, other communication references, such as a hyperlink, can be delivered to the customer (e.g., in response to the customer's selection of the advertisement and/or the customer's preference); and the communication references can be used subsequently to request a connection to the advertiser.
In one embodiment, the telephone number of the advertiser 108 that the directory assistance operator has access to is the telephone number of the advertiser which connects directly to the advertiser. In this case, the operator of the directory assistance service, or an automated system of the directory assistance service connecting the call to the advertiser 108, makes a record of the connection for purposes determining the calls generated for the advertiser from the advertisement. The process 1200 continues to process block 1204. At process block 1204, the call is forwarded to the advertiser of the audio advertisement.
In one embodiment, the advertisement publication module may publish the advertisement on a telephone based advertising service. For example, the advertisement can be delivered to a customer through audio as part of a voice portal or telephone based directory, such as a 411 telephone directory. In another embodiment, the advertisement publication module may publish the advertisement on a web based advertising service. For example, the advertisement can be delivered to a customer through a streaming website that provides audio through the website using voice over IP technology. In another embodiment, the advertisement publication module may publish the advertisement on a web based advertising service that is delivered to a portable device. For example, the advertisement can be delivered to a customer through a website as a text advertisement. In yet another example, the advertising publication module may publish the advertisement on a web page advertising service. For instance, the advertisement can be delivered to a customer through a portable device using a text messaging service that delivers a text message that was abbreviated by the advertisement creation and management module.
The customer phone number can be automatically determined through ANI, or through a user preference setting, or through an entry submitted with the selection of the encoded target phone number. The user, media channel and other useful information can also be identified as a unique user, media channel etc., or at least a unique “device or application” by passing a unique user ID, and Channel ID as parameters of a SIP initiated call.
In one embodiment, the selection of the encoded target phone number 1538 is transmitted to a corresponding media channel, which forwards the request for making the phone call to a server (e.g., a web server) connected to the phone router 1528. Alternatively, the content information can be formatted so that the selection is sent directly to the server that is connected to the phone router 1528.
When the router 1528 starts the phone calls, the encoded target phone number can also include alphabetic characters (and/or other characters). The server and/or the phone router 1528 can decode the encoded target phone number 1538 to recover/retrieve the target phone number 1538 and other associated information, such as the identity of the media channel that is creditable for providing the encoded target phone number to user. Exemplary media channels are a web server 1502, a WAP server 1504, an SMS center 1506, a custom server 1508, a cable television channel 1510, a news press article 1512, a radio station 1514, etc.
In one embodiment, an advertisement is presented to end users around the globe without geographic area limitations. For example, an advertiser may provide services and/or products to customers around the globe. The advertisement may be delivered to the worldwide users of the Internet.
In one embodiment, the intended audience of an advertisement is the population in a particular geographic area or people interested in a particular geographic area. For example, an advertiser may limit its service area within a geographic area, where the advertiser can provide services and/or products to the customers more effectively. For example, a business may better serve the customers within a convenient walking/driving distance to the site of the business. A business may limit the service area within a city, a state, a country, or other types of regional areas. Further, a large business entity having offices around the world may want to attract customers in different geographical regions to different offices for better services.
In one embodiment, an advertisement presented in a media channel is for a single advertiser. The customer selects an advertiser according to the advertisements presented on behalf of individual advertisers. The phone decoder and router 1528 connect the customer and the selected advertiser according to the encoded target phone number 1536 individually publicized in the advertisement for the advertiser. When the customer views the online advertisements, the selection of the advertiser is based on the online information. When the customer listens to audio advertisements, the selection of the advertiser is based on the recorded information.
In one embodiment, an advertisement is presented in a media channel for a group of advertisers, such as a group of mortgage brokers. The advertisement contains an encoded target phone number 1536 which is reachable to the group of mortgage brokers. When the encoded target phone number 1536 is selected or used, the selection of a particular advertiser is performed at the phone decoder and router 1528.
For example, a toll-free number is published to advertise mortgage brokers in a particular geographic area. When a consumer dials the toll-free number, the call is routed to the highest bidding mortgage broker who is available in that market.
The phone decoder and router 1528 may select the target advertiser according to the bidding of the advertisers for the advertisement. The advertiser who places the highest bid is the winner for the call. Alternative, or in combination, other types of selection criteria can also be used. For example, the user may be interested in advertisers in a particular geographical region; and the geographic area of interest to the caller can be determined and used in selecting the target advertiser. Further, the user may be interested in a connection without excessive waiting time. The status of the availability of the advertisers to answer the call can be used in ranking the candidates for routing the call.
In general, an indicator used to rank the candidates may be a function of a number of parameters, such as the bid for the advertisement, the projected waiting time, an indicator showing a degree of matching to one or more user requirements (e.g., geographic area, service type, etc.), advertisement budget, conversion rate, average call duration and others.
Alternatively, information about the customer phone number and the desire to make the phone call according to the advertised phone number can be transmitted to the switch/router 1620 through a communication link other than a phone connection. For example, an email, a fax, an HTTP (HyperText Transfer Protocol)/WAP (Wireless Application Protocol) request, etc., can be used to submit the request for the phone connection. The switch/router 1620 then initiates the phone call to the customer and selects the advertiser for the phone call. In one embodiment, the request is made via a communication protocol such as SIP.
Note that the assigned phone number may also be encoded in a way so that the information about the media channel which provides the phone number to the Customer can be decoded, as discussed above. For example, different media channels may be assigned different phone numbers for reaching the same group of advertisers through the switch/router 1620. According to the phone number in the advertisement, the switch/router 1620 can determine the media channel that is appropriate for the delivery of the phone number to the Customers.
In one embodiment, the availability of the advertisers to answer the call is also considered. In one embodiment, if the top-ranking (e.g., according to the bidding) advertiser receives a call and does not answer after a certain amount of time (e.g. 30 seconds), the call is automatically routed to the second-highest ranking advertiser, and so on. In another embodiment, the missed call is routed to a human concierge who shepherds the call to the appropriate available advertiser or information source.
In one embodiment, the advertiser group includes subgroups of advertisers for different geographic areas. Indications of geographic areas of interest to the callers can be used in the selection process.
In one embodiment, the selection of the geographic area is made when the customer selects the phone number from the advertisements. The phone number is encoded with geographic area information such that, when the phone number is dialed, the geographic area information can be automatically decoded from the phone number dialed; and the geographic area information can be used to rank the advertisers and/or eliminate the advertisers that are not serving the corresponding geographic areas.
In one embodiment, the geographic area information is determined from the location of the customer phone. Alternatively, the customer may specify the geographic area in the phone call to the switch/router 1620, through an automated system or through human concierges. Further, the customer may specify requirements other than geographic areas for selecting the winning advertiser.
In one embodiment, the telephone receiving equipment 1736 and the telephone switching equipment 1738 are circuit switched, including Private Branch Exchange (PBX) and a dedicated voice network. Alternatively, the telephone receiving equipment 1736 and the telephone switching equipment 1738 may be packet switched, including Internet Protocol (IP) based PBX, or a soft-switch, or SIP Servers and Media Servers, a data communication network and a gateway. In general, various telephonic techniques known in the art can be used.
When the telephone receiving equipment 1736 receives a phone call, the control center 1734 determines whether further information is needed and/or can be obtained from the caller. For example, to determine a geographic area of interest, the control center 1734 can instruct the interactive voice response (IVR) system 1728 to prompt the caller to key in the desired zip code. In one embodiment, Interactive Voice Response (IVR) is a telephony technology in which one may use a touch-tone telephone to interact with a database to acquire information from or enter data into the database without the help of a human concierge. In one embodiment, information may also be collected using Voice Recognition technology to get and interpret spoken choices provided by the users.
Further, the control center may direct the IVR system 1728 to prompt the caller to specify further criteria based on the advertiser information 1712. For example, when the phone number is for a group of mortgage brokers, the customer may be directed to select loan sizes, loan types, etc.
Alternatively, the control center 1734 may instruct the geographic area locator 1730 to determine a geographic area from which the call is initiated. For example, the geographic area locator may use the cellular position system to determine the location of a cellular phone, or use a satellite/pseudolite positioning system to determine the location of a mobile device. Pseudolites are ground-based transmitters signals similar to a Global Positioning System (GPS). Pseudolites are useful in situations where signals from an orbiting satellite might be unavailable, such as tunnels, mines, buildings or other enclosed areas. A satellite/pseudolite signal receiver may determine its location and transmit the location through the cellular phone to a cellular communication system, or transmit the received signals to a location server which computes the location.
A cellular communication system may also determine the location of a cellular phone. For example, the location of a cellular phone can be determined using a method known as Time Difference of Arrival (TDOA) in which the reception times of a cellular signal from a mobile station are measured at several base stations to determine the position of the cellular phone. Alternative, a method known as Advanced Forward Link Trilateration (AFLT), or Enhanced Observed Time Difference (EOTD), can be used, which measures the reception times of cellular signals from several base stations to the cellular phone. Alternatively, the cellular site in which the mobile device can communicate to a based station can be used to determine a rough position of the cellular phone. In general, any method used by a cellular phone provider to get location information (e.g., for emergency service) can be used.
The control center 1734 may also instruct the automatic number identification (ANI) unit 1732 to determine the phone number of the incoming call and look up the geographic area information from the database for the phone numbers.
Alternatively, the control center 1734 may connect the phone call temporally to a human concierge who can help the caller to specify a selection criterion (or criteria).
In one embodiment, the control center 1734 uses a number of different types of information to select the winning advertiser based on the advertiser information 1712.
In one embodiment, the advertiser information 1712 include the identities of the advertisers 1702, the geographic areas 1704 of the advertisers, the phone number(s) 1706 of the advertisers, the placement bids 1708 of the advertisers, the availability statuses 1710 of the advertisers, etc. In an alternative embodiment, more or less fields can be used for the advertiser information.
The availability may include the information about the projected waiting time for a caller to get through. The availability may also depend on the advertisement budget specified by the advertiser. For example, the advertiser may specify the advertisement budget in terms of the maximum number of calls in a day, the minimum time intervals between two calls, working hours, etc.
After the advertiser is determined, the control center 1734 can instruct the telephone switching equipment 1738 to connect the incoming phone call to the phone number of the advertiser. The control center 1734 then creates a record entry in connection records 1724 to indicate the connection made for the advertiser. For example, a record entry may include information such as the from phone number 1714, the to phone number 1716, the time the connection is made 1718, the duration of the connection 1720, the media channel 1722 responsible for delivering the advertisement to the caller, the advertisement bid 1724 of the advertiser at the time of the connection, etc. Other information, such as whether or not a human concierge is involved, can also be recorded. In an alternative embodiment, more or less fields can be used for the connection records.
In one embodiment, the recorded connection information is used to generate an invoice to bill the advertisers. An account of the advertiser may be debited automatically for the connection. Alternatively, a payment for the advertisement is collected automatically through an electronic system for the connection.
In one embodiment, the system 1700 can be utilized in a directory assistance service or information service (e.g., 411) process to redirect customer calls to advertisers once an advertisement has been provided to the customer. In one example, the advertisement information 1712 and connection records 1726 can be part of the computer infrastructure of the directory assistance service. In another example, the advertisement information 1712 and connection records 1726 can be part of the computer infrastructure of the advertisement processing service which provides audio advertisements, text advertisements, image advertisements, or multimedia advertisements to the directory assistance service.
At process block 1804, an advertisement is provided on a media channel on behalf of the advertiser. The advertisement can include one of the unique telephone numbers assigned to the advertiser and/or, a reference to the unique telephone number. The process 1800 can continue at process block 1806.
At process block 1806, the telephone calls received at the unique telephone number assigned to the advertiser are monitored. Indications of calls received at the unique telephone number assigned to the advertiser are thereby stored for later, or in real-time, charging the advertiser, depending on the number of calls resulting from the advertisement. The process 1800 continues at process block 1808.
At process block 1808, an advertiser is charged based on phone call activity through the assigned telephone number. Therefore, the telephone number that has been assigned to the advertiser 108 can allow tracking the telephone calls that have been made to the advertiser as a result of the advertisement and charging the advertiser based on a price per call. In one embodiment, the advertiser can be charged for each call received, or connected to the advertiser 108, as a result of the advertisement.
In one embodiment, a connection provider (or router or call handling module) uses a connection server configured on a packet switched network to provide telephone connections between callers (e.g., customers) and callees (e.g., advertisers), as illustrated in
Since the telecommunication carrier (1905) can route a call from a packet switched network to a variety of destinations (e.g., a traditional analog telephone set, a mobile phone, a cellular phone, a WiFi phone, a Bluetooth phone, a softphone running on a computer, etc.), the connection sever (1907) can use one type of communication connection with the telephone carrier (1905) to facilitate the communication connections with variety of devices used by the customers (e.g., callers and callees). Thus, the implementation of the connection server (1907) can be simplified. In one embodiment, the connection server (3307) can also place and/or receive direct VoIP calls to/from the caller (or callee).
For example, to make a voice connection in response to a click-to-call request, the connection server can place separate VoIP calls, via the telecommunication carrier (1905), to the caller (1901) (e.g., the requester of the click-to-call) and the callee (1903) (e.g., the destination of the click-to-call request).
If the caller (1901) (or the callee 1903) is on a public switched telephone network (PSTN), the telecommunication carrier (1905) bridges the packet switched the network and the public switched telephone network (PSTN). The telecommunication carrier (1905) routes the call from the packet switched network (1909) to the caller (1901) (or the callee 1903) on the circuit switched network. Thus, the caller (1901) (or the callee 1903) can use a telephone set to receive the call via a Plain Old Telephone Service (POTS). The connection server (1907) joins the separate calls that are placed via the packet switched network (1909) to connection the callee (1903) and the caller (1901).
In one embodiment, call signaling and media content may use different network paths. While call signaling is arranged to go through the packet switched network (1909) and the connection server (1907), the media stream does not have to go through the connection server (1907). For example, when the calls are joined, the media content may be redirected to flow over the communication carrier (1905) without going through the packet switched network (1909) to the connection server (1907) for improved performance and efficiency. The connection server (1907) can release the control over the media stream to allow the media stream to flow through the shortest path, without going through the connection server, while maintaining control to the connection for the call by staying on the path for call signaling.
In another example, when the caller (1901) initiates a call over a PSTN to the connection server (1907), the telecommunication carrier (1905) converts the call for the packet switched network (1909) for the connection server (1907).
In one embodiment, virtual softphones on the telecommunication carrier (1905) are assigned to the caller (1901) and the callee (1903) for interfacing with the connection server (1907) over the packet switched network (1909). The virtual softphones encapsulates the devices and networks used by the caller (1901) and callee (1903) to access the connection server (1907); and the telecommunication carrier (1905) shields the connection server (1907) from the implementation details of the user devices and networks used by the caller (1901) and the callee (1903). The connection server (1907) calls (or receives calls from) and connects the virtual softphones on the telecommunication carrier (1905) to connect the caller (1901) and the callee (1903).
In
Alternatively, a connection server may include some or all of the functionality of the telecommunication carrier (1905). For example, the connection server may be configured to bridge a packet switched network and a circuit switched network. The connection server may support multiple, different types of Internet Telephony systems.
In one embodiment, the connection server (1907) and the telecommunication carrier (1905) are operated by different, separate entities. Alternatively, the connection server (1907) and the telecommunication carrier (1905) may be operated by the same entity. In another embodiment, the telecommunication carrier (1905) includes a set of facilities operated by a number of separate entities.
In one embodiment, the caller (1901) and/or the callee (1903) may also place/receive calls via a packet switched network. The telecommunication carrier (1905) may route the calls between the caller (1901) and the callee (1903) without using a PSTN. In one embodiment, caller (1901) and/or the callee (1903) may place calls to or receive calls from the connection server (1907) via Internet.
In one embodiment, the session border controller (1906) is configured to control the signaling and media stream during the setting up, conducting and tearing down of VoIP calls to or from the connection server (2005). In some embodiments, the session border controller (1906) may pick up the call that comes to the session border controller (1906), places a separate call from the session border controller (1906), and joins the received call and the placed call to control both the signaling and media stream. In some embodiments, the session border controller (1906) may perform signaling/encoding translation to allow the connection server (2005) to process the VoIP calls in one standard, while receiving VoIP calls in a variety of standards (e.g., SIP, H.323, etc.). In one embodiment, the session border controller (1906) is configured to perform one or more firewall functionalities, such as denial of service protection, call filtering, bandwidth management, etc.
In one embodiment, the session border controller (1906) is configured to perform media releasing operation. When the session border controller (1906) determines that the source and destination of a media stream is on the same side of the session border controller (1906) (e.g., both the source and the destination of the media stream is outside the connection server 2005), the session border controller (1906) can release the hairpining of the media stream and allow the media stream to flow without going through the session border controller (1906).
In
For example, when an incoming message for the initiation of a call is received (e.g., a SIP INVITE message from the telecommunication carrier 1905), the session border controller (2001) may route it to a SIP server (e.g., 2011) for processing. The INVITE message includes the phone number dialed by the caller and the contact information about the caller (e.g., the phone number of the caller 1901 and/or the identity of the virtual SIP phone at the telecommunication carrier 1905).
The SIP server may determine whether the phone number dialed by the caller (1903) is sufficient to determine the phone number of the callee (e.g., 1903). If the phone number of the callee (e.g., 1903) can be determined from the phone number dialed by the caller (1903) (e.g., via decoding the phone number dialed by the callee, or looking up the phone number of the callee from a table using the phone number dialed by the caller as a key), the SIP server can place a separate SIP call to the callee via the packet switched network (2003) and then connect the caller and the callee. Alternatively, the SIP server can further route the SIP INVITE message (e.g., to the telecommunication carrier (1905) to direct the call to the callee. For example, the SIP server may modify the INVITE message by replacing the destination with the determined phone number of the callee. Further, the SIP server can modify the INVITE message by removing the phone number of the caller (or replacing the phone number of the caller with a phone number of the connection server). In one embodiment, the modified INVITE message identifies the virtual softphone corresponding to the caller on the telecommunication carrier as the SIP phone initiated the call; thus, the virtual softphone corresponding to the callee on the telecommunication carrier can establish media connection with the virtual softphone corresponding to the caller on the telecommunication carrier directly. Alternatively, the modified INVITE message may identifies a media server (2021) (or a virtual softphone on SIP server) as the initiator for a separate call. The SIP server then connects the calls for the media stream.
In one embodiment, the caller is first connected to a media server (e.g., 2021, 2023, or 2029). For example, the SIP server may forward the SIP INVITE message to one or more of the media servers for answering the call. When a media server (e.g., 2021) answers the call, a prompt is played to the caller by the media server. The media server may include an Interactive Voice Response (IVR) system, or be connected to an IVR system, to obtain input from the caller.
For example, the media server may prompt the caller to enter the extension assigned to the callee, such that the phone number of the callee can be determined based on the phone number including the extension dialed by the caller. In some embodiments, the extension dialed by the caller is sufficient to determine the phone number of the callee. After the phone number of the callee is determined, the SIP server can further connect the call to the callee.
For example, the media server can send a message to the SIP server. The message identifies the call and the extension obtained from the caller. The SIP server then determines the callee's phone number based at least on the extension received from the media server and initiates a SIP call via the packet switched network (2003) (e.g., by sending a SIP INVITE message to the telecommunication carrier 1905, which further bridges the call to the callee 1903). Then, the SIP server disconnects the media server from the call and reconnects the call to the callee.
For example, the SIP server can send a SIP BYE message to the media server to disconnect the media server from the call (e.g., by sending a “BYE” message to the media server for the call) and send a re-INVITE message towards the caller to connect the caller and the callee. Alternatively, the media server may send a SIP BYE message to the SIP server for the call; the BYE message may include the extension obtained from the caller; in response to the BYE message that contains the extension, the SIP server determines the phone number of the callee and further connects the caller to the callee.
In one embodiment, the SIP server can direct the caller and the callee to connect to each other for the media stream without having the media stream going through the session border controller (2001) into the connection server (2005). For example, the media stream can go through the telecommunication carrier (1905) in
However, the SIP server stays on the signaling path to monitor the progress and termination of the call. The SIP server can also break the connection between the caller and the callee, or force the media stream to come through the connection serve (2005). For example, the SIP server may selectively conference a media server into the call to monitor and/or record the communication of the call between the caller and the callee. For example, the SIP server may reconnect the caller and the callee to separate media servers for interaction with an IVR system or a human operator to confirm a deal or transaction.
Similarly, the SIP server may initiate a callback to a caller via a SIP call over the packet switched network (2003) for a connection to the caller. The SIP call may be bridged onto a circuit switched network (e.g., by a telecommunication carrier 1905). The SIP server can then reconnect the call to a media server for sending a prompt to the caller before reconnect the call to the callee. Alternatively, the callback can be initiated from a media server; and the call signaling (e.g., the INVITE message from the media server) goes through the SIP server for call control. Alternatively, the SIP server sends out the INVITE message on behalf of the media server.
In one embodiment, the SIP servers (2011, 2013, . . . , 2019) and media servers (2021, 2023, . . . , 2029) are implemented on separate computers connected via a local area network (and/or intranet or Internet). Alternatively, at least the some of the servers can be implemented on a same computer. In one embodiment, the SIP servers and the media servers are also integrated with the session border controller (2001) on a same data process system having multiple processors coupled with a data bus. In one embodiment, the SIP servers are coupled to the media servers via a network; and a SIP server may use any of the available media server for interaction with the caller (or callee). Alternatively, a SIP server may be configured to use one or more of media servers that are not shared by other SIP server. For example, a SIP server may be implemented on a same data processing system with one or more media servers which are reserved for the SIP server.
In one embodiment, the connection server (2005) may further include a database server (2005) to storing records related to the calls, data mapping between the communication references assigned to the callees and the actual phone numbers of the callees, etc. In one embodiment, contact mapping are cached in the local memory (e.g., RAM) of the servers for improved performance; and the cached mapping is updated when the database is updated.
In general, the routines executed to implement the embodiments of the invention may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processors in a computer, cause the computer to perform operations necessary to execute elements involving the various aspects of the invention.
