Abstract
A system is provided that responds to a received transaction. The system detects a received transaction generated by a transaction initiator and associates a resource locator, such as a uniform resource locator (URL), with the received transaction. The URL is then provided to the transaction initiator. The URL associated with the received transaction may identify an Internet web page, which can be generated in response to the received transaction. The received transaction includes a request to receive a URL. The received transaction can be a telephone call initiated by a telephone caller. The system is also capable of identifying the transaction initiator and associating a URL with the received transaction based on the transaction initiator's identity. The transaction is received on a first communication medium and the URL is associated with a second communication medium.
Description




FIELD OF THE INVENTION




The present invention relates to a system for communicating information. More specifically, a system is disclosed for communicating information, including visual data, between two devices or individuals, such as a transaction processing system and an initiator of a transaction.




BACKGROUND




Known systems are available for communicating information between two devices, such as a telephone communication system that communicates information between two telephones across a public switched telephone network (PSTN). A telephone allows an individual to contact another individual by dialing a particular telephone number. Once the connection is established, the two individuals communicate by talking to one another. Since most organizations use telephones (including private branch exchanges (PBXs)), and a majority of individual households have at least one telephone, the conventional telephone is an efficient and popular communication system.




In a conventional telephone system, only audible information is exchanged between the two individuals. Thus, the individuals cannot see the other person or exchange any visual information. Using this type of system, an individual calling an organization requesting additional information about a product or service, must rely on audible information (either from a live person or a recorded message). Visual information is not exchanged in a conventional telephone system.




Telephones that incorporate video data with the audible data (commonly referred to as videophones) have been developed. However, these videophones are relatively expensive and require specialized hardware (the videophone) at each end of the telephone communication link. Unless videophones gain increased consumer acceptance, most telephone communications will be limited to conventional telephones exchanging audible data. Furthermore, videophones do not typically permit the transmission of transactional data between the users of the system. For example, a user of a videophone cannot typically transmit data, such as computer-based data, to the other individual or system. The users are generally limited to exchanging information audibly and displaying information or objects to the camera such that an image of the information or object is communicated to the other individual or system.




Existing systems are available for establishing a connection between two individuals across the Internet (commonly referred to as Internet Phones). These Internet Phones allow the communication of both visual data and audible data between the two individuals. Although the popularity and utilization of the Internet is growing quickly, Internet Phones are less convenient than conventional telephones because they require custom software and cannot exchange visual data with a conventional analog telephone. Furthermore, a limited number of individuals and organizations use Internet Phones on a regular basis. A person or organization that does not use an Internet Phone cannot be contacted by another individual or organization using an Internet Phone.




Existing communication systems do not permit the augmenting of a non-visual communication path (e.g., a telephone call) with visual data or transactional data having a defined structure. Existing telephone systems are limited to communicating only non-visual data. Videophones are limited to communicating non-visual data and non-transactional visual data. Videoconferencing systems are also limited to communicating non-visual data and non-transactional visual data.




It is therefore desirable to provide a mechanism that provides a convenient and efficient system for exchanging both transactional data and audible data between two individuals or systems.




SUMMARY OF THE INVENTION




The present invention is related to a system for communicating information, including visual data, between two devices or individuals. For example, embodiments of the present invention communicate information, including visual data, between a transaction processing system and an initiator of a transaction. In an embodiment of the invention, the transaction initiator is able to communicate with the transaction processing system using a telephone. The transaction processing system provides the transaction initiator with a resource locator, such as a uniform resource locator (URL). The resource locator is used by a computer or other processing device to retrieve information, such as information contained in Internet web pages, associated with the resource locator.




An embodiment of the invention responds to a received transaction by detecting a received transaction generated by a transaction initiator. A uniform resource locator (URL) is associated with the received transaction. The URL is then provided to the transaction initiator.




In a particular embodiment of the invention, the received transaction includes a request to receive a URL.




Another embodiment of the invention generates an Internet web page in response to the received transaction and associates the generated web page with the URL.




In one embodiment of the invention, the received transaction is a telephone call.




An embodiment of the invention identifies the transaction initiator and associates a URL with the received transaction based on the transaction initiator's identity.




In other embodiments of the invention, the transaction is received on a first communication medium and the URL is associated with a second communication medium.




Another embodiment of the invention responds to a telephone call initiated by a telephone caller by associating a resource locator with the received telephone call and providing the resource locator to the telephone caller.

DETAILED DESCRIPTION




The following detailed description sets forth numerous specific details to provide a thorough understanding of the invention. However, those of ordinary skill in the art will appreciate that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, protocols, components, algorithms, and circuits have not been described in detail so as not to obscure the invention.




The present invention is related to a system for communicating information, including visual data, between two devices or individuals. For example, the present invention is capable of communicating information, including visual data, between a transaction processing system and an initiator of a transaction. In an embodiment of the present invention, the transaction initiator is able to communicate with the transaction processing system using a conventional telephone. The transaction processing system provides the transaction initiator with a resource locator, such as a uniform resource locator (URL). The resource locator is used by a computer or other processing device to retrieve information, such as information contained in Internet web pages, associated with the resource locator. Thus, the transaction initiator is able to communicate with the transaction processing system using both the conventional telephone (for audible information) and the computer (for visual information). The communication of the resource locator to the user's computer can be performed automatically, such that the process is transparent to the user. Embodiments of the present invention allow the transaction processing system (or an agent coupled to the transaction processing system) to simultaneously illustrate and describe a particular topic or item, without requiring the transaction initiator to use specialized hardware or software. Furthermore, the transaction processing system is capable of exchanging transactional information and other computer-based data with the transaction initiator.




Particular embodiments of the invention are described herein with reference to URLs. A URL is one type of resource locator that may be utilized with the present invention. However, those of ordinary skill in the art will appreciate that the teachings of the present invention can be used with any type of resource locator or other identifier.




Embodiments of the invention allow a telephone caller to request information from an information source in the form of a web page. This information may be provided automatically by the information source or selected by an agent based on the conversation with the telephone caller. Thus, rather than describing a product or service audibly using only the telephone connection, an agent or system is able to display information about the product or service to the caller while continuing to describe the product or service audibly. The invention may also be used in place of an integrated voice response system. Instead of providing the caller with a prerecorded list of options that are selected with the telephone keypad, the caller's computer displays a web page containing the various options, including options to display more information about a product or service.




Particular embodiments of the invention are described below with reference to a transaction processing system. A transaction processing system is any device capable of receiving, transmitting, queuing, routing, or otherwise processing a transaction. A transaction processing system may also handle mixed transactions (e.g., receive a telephone call and respond to the telephone call using electronic mail). Example transaction processing systems include automatic call distributors (ACDs), and other telephone processing devices. A particular transaction can be either inbound or outbound. Exemplary transactions include telephone calls, video sessions, or an Internet session. Although particular embodiments of the invention are described for processing telephone calls, those of ordinary skill in the art will appreciate that the teachings of the invention can be applied to any type of transaction. In particular, the teachings of the present invention may be applied to any type of real-time transaction.





FIG. 1

illustrates an embodiment of a communication system capable of implementing the teachings of the present invention. A telephone


10


is coupled to a public switched telephone network (PSTN)


12


. A transaction processing system


14


is also coupled to PSTN


12


. Transaction processing system


14


is capable of receiving, transmitting, and processing various types of transactions, such as telephone calls. PSTN


12


may be any type of switching system or data communication network capable of establishing a connection between telephone


10


and transaction processing system


14


. Although

FIG. 1

shows telephone


10


coupled directly to PSTN


12


, in alternate embodiments of the invention telephone


10


part of a private branch exchange (PBX) system, which is coupled to PSTN


12


.




A web server


16


is coupled to transaction processing system


14


and maintains multiple web pages identified by URLs, such as web page


18


. In

FIG. 1

, web server


16


is shown coupled directly to transaction processing system


14


. However, in alternate embodiments of the invention, web server


16


is indirectly coupled to transaction processing system


14


through a network, such as the Internet, or other communication mechanism. Web server


16


is also coupled to a network


20


(e.g., a local area network (LAN), a wide area network (WAN), the Internet or an intranet network). In a particular embodiment of the invention, web server


16


is contained within transaction processing system


14


. Web server


16


may be any device capable of maintaining and distributing web pages. In alternate embodiments, web server


16


can be any device capable of distributing information (e.g., a server capable of distributing information across a network to one or more computers). In particular embodiments of the invention, PSTN


12


and network


20


may be combined in a single network or entity.




A computer


22


is coupled to network


20


and telephone


10


. The coupling between computer


22


and telephone


10


may be a physical connection (e.g., a serial communication link) or a logical connection (e.g., through a common interface device coupled to telephone


10


, computer


22


, and network


20


). Computer


22


is capable of communicating information across network


20


and communicating with telephone


10


. Although telephone


10


and computer


22


are shown as two separate devices in

FIG. 1

, in alternate embodiments of the invention, telephone


10


and computer


22


are contained in a single device. Other embodiments of the invention use a software-based telephone implemented by computer


22


, thereby eliminating the need for a separate telephone


10


. These other embodiments of the invention use a modem contained within computer


22


to initiate and receive telephone calls across PSTN


12


. Alternatively, an Internet Phone may be used to establish an audible connection between a transaction initiator and a transaction processing system.




Multiple agents (e.g., telephone agents)


24




a,




24




b,


and


24




n


are coupled to transaction processing system


14


. A particular transaction processing system may have any number of agents capable of handling various transactions. For example, a telephone processing system may use multiple telephone agents, in which each agent has a telephone (or similar device) and a computer. The agent uses the telephone to communicate verbally with the transaction initiator via the PSTN. Additionally, the agent uses the computer to display information about the transaction initiator and determine which web pages are provided to a user (i.e., which web page or pages are associated with the URL provided to the transaction initiator). Although various embodiments of the invention are illustrated and described as using agent interaction, the invention can be implemented without any agent interaction. For example, an automated process may communicate information to the transaction initiator and receive information from the transaction initiator without requiring the interaction of an agent.




For purposes of illustration,

FIG. 1

shows a single telephone


10


and a single computer


22


coupled to PSTN


12


and network


20


, respectively. However, those of ordinary skill in the art will appreciate that PSTN


12


, transaction processing system


14


, web server


16


, and network


20


can support multiple telephones and computers simultaneously. Furthermore, web server


16


may be coupled to multiple transaction processing systems, thereby maintaining web pages generated and used by multiple transaction processing systems. A particular web page contained in web server


16


can be accessed by multiple computers simultaneously.





FIG. 2

is a flow diagram illustrating an embodiment of a procedure for processing transactions. At step


30


, a call is initiated from a telephone (e.g., telephone


10


in FIG.


1


). The call initiated in step


30


may include a request from the call initiator to receive a URL. In the case of a telephone, the call initiator is the user of the telephone. However, in other embodiments, the transaction initiator can be a processing device or an algorithm (e.g., a computer containing a software-based telephone may automatically dial a number associated with a transaction processing system). The request to receive a URL may be a particular message dedicated to requesting URLs or may be part of another call setup message. For example, with an ISDN connection, a new “URL request” message may be created to request a URL from a transaction processing system. Alternatively, a temporary signaling connection may be established between the transaction initiator and the transaction processing system to allow the exchange of various messages. Further, a URL request may be embedded in an existing message, such as the call setup message.




At step


32


, a transaction processing system (e.g., transaction processing system


14


in

FIG. 1

) receives an incoming call notification. This incoming call notification results from the call initiated in step


30


. At step


34


, the procedure determines whether a URL request was contained in the incoming call. If no URL request was contained in the incoming call, then the procedure branches to step


36


to process the incoming call without providing a URL to the call initiator. Thus, step


36


processes the incoming call in a conventional manner, for example, by providing the call to a telephone agent or playing a recorded message to the call initiator.




If step


34


of

FIG. 2

identifies a URL request in the incoming call, then the procedure continues to step


38


, where the transaction processing system identifies or generates a web page having an associated URL. The URL is associated with the incoming call, thereby associating the web page with the incoming call. The web page identified or generated at step


38


can be based on the call initiator's telephone number, and may be unique to the call initiator. Alternatively, a particular URL may be associated with multiple incoming calls or multiple call initiators (e.g., multiple callers may view the same web page). For example, the transaction processing system can maintain a database of call initiators (e.g., customers of an organization). This database may contain additional information about a particular call initiator, such as account information or prior purchases. This additional information can be used to select a type or category of web page (e.g., a particular product advertisement or other information likely to be of interest to the caller). At step


40


, the transaction processing system provides the URL to the telephone call initiator (e.g., via PSTN


12


in FIG.


1


).




At step


42


, the telephone call initiator receives the URL from the transaction processing system and passes the URL to a computer coupled to the initiator's telephone. For example, in the embodiment of

FIG. 1

, the URL is received by the initiator's telephone


10


and automatically passed to computer


22


coupled to telephone


10


. Embodiments of the invention allow the telephone to directly communicate the URL to the computer across a communication link. In other embodiments, an interface device is coupled to the telephone, the computer, and one or more networks. The interface receives signals from the network(s) and communicates the signals to the telephone or the computer, as appropriate. Thus, the interface communicates a received URL to the computer and communicates telephony signals to the telephone.




At step


44


, the caller's computer contacts a web server via a network (e.g., the Internet) and retrieves one or more web pages associated with the URL provided by the transaction processing system. Various types of software applications, such as web browsers, may be used to retrieve web pages from a web server. The caller's computer may be configured such that a web browser is automatically executed in response to the receipt of a URL from the caller's telephone, thereby automatically retrieving the web pages associated with the received URL. At step


46


, the computer displays the web pages retrieved from the web server to the telephone call initiator. At this point, both an audible connection (via the PSTN) and a data connection (via the network) have been established between the call initiator and the transaction processing system. Thus, the call initiator can communicate verbally with an agent of the transaction processing system using the telephone while simultaneously retrieving visual information in the form of web pages.




In a particular embodiment of the invention, the transaction processing system always provides a URL to the telephone that initiated the telephone call. If the telephone is capable of receiving and utilizing a URL, then the call initiator can view the web page associated with the URL. However, if the telephone is incapable of receiving a URL or the call initiator is not interested in viewing the web page, then the URL is ignored or discarded by the telephone that initiated the call. Therefore, in this embodiment, the telephone or device initiating the call is not required to request a URL.




In other embodiments of the invention, the transaction processing system identifies the telephone number or other identifier associated with a received call. Based on information known about the call initiator, the transaction processing system determines whether to automatically provide a URL to the call initiator. For example, customers of an organization operating the transaction processing system may notify the organization that they have the capability to receive and utilize a URL. The organization maintains a table of such customers based on the customer's telephone number, account number, or other identifying information. If the transaction processing system receives a call from a customer listed in the table, then the transaction processing system automatically provides a URL to the customer. Thus, the customer does not need to request a URL each time a call is placed to the organization.




The flow diagram of

FIG. 2

illustrates a procedure for retrieving one or more web pages from a web server based on a URL provided to the telephone call initiator from a transaction processing system. In a particular embodiment of the invention, the web page associated with the URL provided by the transaction processing system is dynamic; i.e., the information contained in the web page(s) may be changed or updated by the transaction processing system. In this situation, the browser or other software application used by the computer to retrieve web pages from the web server may continually check the web server for changes or updates to the web page. In this manner, the web page displayed to the telephone call initiator is dynamic, and changes to reflect, for example, the topic currently being discussed with a telephone agent using the transaction processing system.




When the transaction processing system receives a request from a telephone caller for a URL (or otherwise determines that the caller can receive URLs), the transaction processing system may generate a custom web page for the caller having a unique URL. That URL is provided to the caller, thereby allowing the caller to view the custom web page on the caller's computer. The custom web page may contain, for example, information regarding the caller's account balance or information regarding pricing and availability of various products of interest to the caller. The custom web page may be generated temporarily for use during the telephone call and deleted when the call is terminated. Alternatively, the custom web page can be maintained in the web server after the telephone call has ended, thereby allowing the caller to access the information contained in the web page at a later time. The web server can be configured to automatically purge web pages after a particular time period (e.g., two days after the web page was last accessed).




An exemplary use of the invention allows a telephone caller to request information from an information source in the form of a web page. In this example, the telephone caller initiates a call to a telephone number associated with a transaction processing system or other information source. The transaction processing system provides a URL to the telephone caller. The web page associated with the URL contains information requested by the caller. For example, the transaction processing system may allow the caller to select information using voice commands or commands entered through the telephone keypad. The selected information is then displayed to the user in one or more web pages.




Another embodiment of the invention allows a telephone agent using a transaction processing system to generate or identify web pages for viewing by the caller. For example, the caller and the telephone agent may be discussing a particular product of interest to the caller. Rather than describing the product audibly using only the telephone connection, the agent is able to display a picture of the product to the caller and further describe the product's features audibly as the caller views the web page. The agent may select several different web pages for viewing by the caller, in which each web page displays a different feature of the product.




Other embodiments of the invention are used when a telephone caller is placed on hold by the transaction processing system. For example, a telephone caller initiates a call to a catalog sales department. If all telephone agents are busy with other customers, the caller is placed on hold. While on hold, web pages are displayed to the caller (the web pages are associated with a URL provided to the caller, as discussed above). If the transaction processing system is capable of identifying the caller (e.g., using the caller's phone number), the system may select or generate web pages containing information likely to be of interest to the caller. In addition to the information contained in the web pages, the caller may receive an audible message through the telephone that further describes the information contained in the web page being viewed by the caller.




A further embodiment of the invention permits the caller to provide information to the transaction processing system using the web page. For example, if a user is placed on hold, the transaction processing system may prompt the user to provide various information (e.g., name, account number, or the reason for the call) through the web page instead of a keypad. The user enters information on the web page using a computer keyboard, voice recognition system, or other user input mechanism. The information provided can be used by the transaction processing system to route the caller to a particular agent or group of agents that are familiar with the caller or familiar with the reason for the call.




The present invention can also be used to provide an alternate contact mechanism if the transaction processing system (or its agents) are busy. In this situation, the telephone caller is provided with an option to contact the called agent by sending an e-mail, sending a fax, or paging a particular agent or group of agents. These alternate contact mechanisms can be implemented automatically for the caller. For example, if the user chooses to send an e-mail to a particular agent, the user can enter the e-mail message on the web page, and an e-mail application executed by the web server or the transaction processing system automatically generates and sends an e-mail message to the particular agent.




In certain situations, a transaction processing system may receive an incoming call notification, but may not be capable of accepting the call for processing (e.g., all agents are already busy and all queues are full). If a particular call cannot be accepted, then the transaction processing system may provide a URL to the caller without answering the call. The web page associated with the URL informs the caller that the system is unable to answer the call, and provides the user with alternate options (e.g., leave an e-mail message, request that an agent call the user, or browse web pages containing information about the organization called by the caller). Since the transaction processing system does not answer the incoming call, no connect charges are incurred because no connection was established. Typically, these connect charges are incurred by the operator of the transaction processing system that provides a toll-free number used by callers.




Particular embodiments of the invention are discussed in which a request receive a URL is generated by a telephone used by a call initiator. However, in alternate embodiments of the invention, a request to receive a URL may be generated by any device or system. For example, in the configuration of

FIG. 1

, a device within PSTN


12


may generate the request to receive a URL. Alternatively, any other device capable of communicating with the transaction processing system may be used to generate a request to receive a URL.





FIG. 3

illustrates another embodiment of a communication system capable of implementing the teachings of the present invention. The embodiment of

FIG. 3

uses an Integrated Services Digital Network (ISDN) line


64


for communications between a caller and a transaction processing system. A telephone


60


and a computer


62


are coupled to ISDN line


64


. ISDN line


64


communicates information between telephone


60


, computer


62


, and a transaction processing system


68


using PSTN


66


. A network


70


(i.e., the Internet or an intranet network) is coupled to PSTN


66


. A web server


72


is coupled to transaction processing system


68


and network


70


. Web server


72


contains one or more web pages


74


for distribution across network


70


. The particular web pages maintained by web server


72


may be generated or edited by transaction processing system


68


, and then provided to web server


72


. In the embodiment of

FIG. 3

, a separate communication line from computer


62


to network


70


is not required because ISDN line


64


is capable of handling both analog voice data from telephone


60


and the digital data communicated between computer


62


and web server


72


. Although not shown in

FIG. 3

, transaction processing system


68


may include any number of agents for handling various transactions.




In the system of

FIG. 3

, a telephone call is initiated by telephone


60


and received by transaction processing system


68


via PSTN


66


. If the incoming call (received by transaction processing system


68


) includes a request to receive a URL, then transaction processing system


68


identifies or generates a web page having an associated URL. This URL is associated with the incoming call and provided to the telephone call initiator via PSTN


66


(using ISDN line


64


). Telephone


60


receives the URL and passes it to computer


62


. Computer


62


then contacts web server


72


via PSTN


66


and network


70


, and retrieves one or more web pages associated with the URL. The retrieved web pages are then displayed to the user of the computer (e.g., the telephone call initiator).





FIG. 4

illustrates an embodiment of a communication system capable of implementing the present invention using an Internet phone. A computer


80


includes an Internet browser application


82


and an Internet phone application


84


. Internet browser


82


can be any type of browser capable of the retrieving and displaying web pages from the Internet. Similarly, Internet phone


84


can be any type of Internet-based telephone application capable of the establishing a connection across the Internet to a transaction processing system


88


. Transaction processing system


88


can include any number of agents for handling various transactions. Transaction processing system


88


is coupled to Internet


86


and to a web server


90


, which maintains one or more web pages


92


. In an alternate embodiment of the invention, transaction processing system


88


is not directly coupled to web server


90


. Instead, transaction processing system


88


and web server


90


communicate with one another using Internet


86


. In alternate embodiments of the invention, the system illustrated in

FIG. 4

may use an ISDN phone embedded in computer


80


. In this embodiment, the ISDN phone replaces Internet phone


84


.





FIG. 5

is a flow diagram illustrating an embodiment of a procedure for processing transactions. The procedure illustrated in

FIG. 5

may be used in connection with the configuration shown in FIG.


4


. At step


100


, a call is initiated from an Internet phone running on a computer (e.g., Internet phone


84


running on computer


80


). The initiated call may include a request to receive a URL. At step


102


, the transaction processing system receives an incoming call notification via the Internet. At step


104


, the procedure determines whether a URL was requested in the incoming call. If no URL was requested, then the procedure branches to step


106


to process the incoming call without providing a URL to the call initiator.




If a URL request was contained in the incoming call, then the procedure continues to step


108


, where the transaction processing system identifies or generates a web page having an associated URL. At step


110


, the transaction processing system provides the URL to the call initiator (in the example of

FIG. 4

, to computer


80


). At step


112


, and Internet browser running on the computer contacts the web server and retrieves one or more web pages associated with the URL. At step


114


, the Internet browser displays the web pages to the user of the computer.




In the embodiment of

FIG. 4

, a single communication link between computer


80


and Internet


86


may be sufficient to handle both the Internet telephone call and the retrieval of web pages from web server


90


. Thus, the user of computer


80


does not require two separate telephone lines to establish both a voice connection for audible data and data connection for communicating web page data.





FIG. 6

illustrates another embodiment of a communication system capable of implementing the present invention. A telephone


130


is coupled to a private branch exchange (PBX)


132


, which is coupled to a PSTN


134


. Although a single telephone


130


is shown in

FIG. 6

, any number of telephones can be coupled to PBX


132


. Various signals are communicated between PBX


132


and a transaction processing system


136


using PSTN


134


. Transaction processing system


136


is coupled to a web server


138


, which contains multiple web pages


140


. Web server


138


is coupled to a network


142


, such as the Internet or an intranet network. In an alternate embodiment of the invention, transaction processing system


136


is also coupled to network


142


, thereby allowing transaction processing system


136


to communicate directly with network


142


, rather than through web server


138

FIG. 7

is a flow diagram illustrating an embodiment of a procedure for processing transactions using the system of FIG.


6


. At step


160


, a call is initiated from a telephone coupled to a PBX (e.g., telephone


130


coupled to PBX


132


). The call initiated at step


160


may include a request to receive a URL. At step


162


, the transaction processing system receives an incoming call notification. At step


164


, the procedure determines whether a URL request was contained in the incoming call. If a URL request was not contained in the incoming call, the procedure branches to step


166


, where the incoming call is processed without providing a URL to the call initiator. If a URL request was contained in the incoming call, the procedure continues from step


164


to step


168


, where the transaction processing system identifies or generates a web page having an associated URL. This URL is associated with the telephone call initiator. At step


170


, the transaction processing system provides the URL to the telephone call initiator (e.g., PBX


132


in FIG.


6


). At step


172


, the PBX receives the URL and passes it to a CTI server (e.g., CTI server


146


in FIG.


6


). At step


174


, the CTI server provides the URL to a computer via a local area network. At step


176


, a browser application running on the computer contacts the web server and retrieves one or more web pages associated with the URL. At step


178


, the browser displays the retrieved web pages to the user of the computer (e.g., the telephone call initiator).





FIG. 8

illustrates an embodiment of a communication system including an information provider that associates URLs with transaction initiators. A telephone


180


is coupled to a PBX


182


, which is coupled to a PSTN


184


. In alternate embodiments of the invention, telephone


180


is coupled directly to PSTN


184


, as illustrated and discussed above. A transaction processing system


186


is coupled to PSTN


184


and communicates with telephone


180


using PSTN


184


. Although not shown, transaction processing system


186


may include any number of agents to handle various transactions. Transaction processing system


186


is coupled to a CTI server


188


, which is coupled to a web server


192


and the Internet


190


. Web server


192


contains multiple web pages that may be generated or edited by transaction processing system


186


.




An information provider


194


is also coupled to Internet


190


. As discussed in greater detail below, information provider


194


is used to associate URLs, network addresses, or other identifiers with a transaction initiator. In an alternate embodiment of the invention, information provider


194


is coupled directly to transaction processing system


186


. In another embodiment of the invention, the functions provided by information provider


194


are incorporated into transaction processing system


186


.




A computer


198


is coupled to an Internet Service Provider


196


, which is coupled to Internet


190


. In an alternate embodiment of the invention, computer


198


is coupled to Internet


190


without the use of an Internet Service Provider. Computer


198


includes an Internet browser


199


capable of retrieving web pages from web server


192


. As shown in

FIG. 8

, no direct connection is provided between telephone


180


and computer


198


. Further, no direct communication link is provided between PBX


182


and computer


198


. As discussed below, telephone


180


and PBX


182


have no direct method for providing a URL to computer


198


. Instead, the association of a URL with a transaction initiator is provided by information provider


194


in combination with information received from transaction processing system


186


. Information provider


194


maintains a registry of transaction initiators, including a unique identifier associated with each transaction initiator, and an associated network address of the computer used by the transaction initiator. In other embodiments, computer


198


includes a separate client process that interacts with the system that handles the registration process (e.g., information provider


194


). In this embodiment, each time the user of computer


198


logs onto the Internet (and is therefore able to receive data or access data across the Internet), the client process automatically notifies information provider


194


. Similarly, when the user logs out, the client process automatically notifies information provider


194


. Thus, information provider


194


knows when the user is available to receive information or access information across the Internet (e.g., receive information or access information from transaction processing system


186


).





FIGS. 9A and 9B

represent a flow diagram illustrating an embodiment of a procedure for processing transactions using the system of FIG.


8


. At step


200


, a call is initiated from a telephone coupled to a PBX (e.g., telephone


180


coupled to PBX


182


in FIG.


8


). The call may include a unique identifier, such as a phone number, account number, or other identification code. At step


202


, the transaction processing system receives an incoming call notification. Step


204


determines whether the incoming call includes a unique identifier. If a unique identifier is not included in the incoming call, the procedure branches to step


206


where the incoming call is processed without providing a URL to the transaction initiator. If the incoming call includes a unique identifier, the procedure continues from step


204


to step


208


, where the transaction processing system identifies or generates a web page having an associated URL. At step


210


, the transaction processing system provides the URL and the unique identifier to an information provider (e.g., information provider


194


in FIG.


8


). In step


212


, the information provider receives the URL and the unique identifier. Step


214


determines whether a user (transaction initiator) is associated with the unique identifier. Additional details regarding the identification of a particular user associated with the unique identifier are provided below. If a user is not associated with the unique identifier, the procedure branches to step


216


and notifies the transaction processing system that the user is not associated with the identifier. At this point, the transaction processing system may handle the incoming call using only a voice connection via a PSTN.




If step


214


of

FIG. 9A

determines that a user is associated with the unique identifier, then the procedure continues to step


218


(FIG.


9


B), where the information provider identifies the network address of the user associated with the unique identifier. At step


220


, the procedure determines whether the identified user is logged into the network. This determination, as discussed in greater detail below, may be performed by searching for the user's network address or by performing a query of the appropriate Internet Service Provider. If the user is not logged into the network, then the procedure branches to step


222


to notify the transaction processing system that the user is not available. In this situation, the transaction processing system handles the incoming call using only a voice connection across the PSTN. However, if the user is logged into the network, then the procedure continues from step


220


to step


224


, where the information provider communicates the URL to the identified user. The URL can be communicated to user's network address, which may be processed by an Internet Service Provider. At step


226


, a browser application running on the user's computer contacts the web server and retrieves one or more web pages associated with the URL. At step


228


, the browser displays the web pages to the user of the computer (e.g., the telephone call initiator).
