If you're over thirty years of age, then you probably remember answering machines. What a breakthrough in communications technology! Answering machines became popular among the masses in the early 1980s as just about everyone who subscribed to a telephone service had one of those little black recording devices networked on their landline. Prior to answering machines, when placing a call, a caller was guaranteed one of three experiences: having his call answered, getting a “busy” signal, or listening to endless rings. Answering machines were revolutionary in that their use rendered endless rings as an obsolete feedback. With an answering machine in use, callers were guaranteed that somebody, or something, was going to answer the call.
While many folks, even today, still make use of the answering machine, the technology has long since advanced to what is commonly known as voicemail. Unlike an answering machine, a subscriber to a voicemail service advantageously doesn't have to be physically near his landline in order to listen to a message. Further, the digital nature of a voicemail system affords users access to many features including call forwarding, archiving, remote access, etc. The advantages of modern day voicemail are numerous. Regardless, whether one subscribes to voicemail or still uses an answering machine, the common feature between the two methods is that there is always the investment in a tangible, personal telephone (or cellular/mobile telephone) involved. As the evolution of voice messaging currently stands, if you can't afford, or don't have access to, a personal telephone and its corresponding service, then voice messaging is not a technology from which you may benefit.
In Africa and developing countries, many residents do not have access to a personal telephone or telephone service, much less voicemail. In fact, market studies have found that 50% of the working population in such markets cannot even afford a $10 per month mobile telephone service, much less an in-house telephone service. Further, due to illiteracy and myriad indigenous languages, the use of voice communication is predictably more usable than text messaging for this type of market. In fact, voice communication versus text communication has been found to have a lopsided ratio of 13:1 in Africa. With that in mind, one should not be surprised that markets such as these rely on a public pay telephone network as a predominant means for communication between remote parties.
If communities in Africa and other developing countries were still organized solely around a model of isolated, autonomous, self-sustaining villages, then perhaps a reasonably accessible public pay telephone network would be adequate to supplement the 99% of communication that would, undoubtedly, take place in a face to face manner. As countries such as Africa have continued to develop and grow, however, a large population of migrant workers has emerged.
Migrant workers in Africa leave their families and communities for long periods of time as they travel to work at remote jobsites. Once at the jobsite, or en route to the jobsite, it can be challenging, if not impossible, for a migrant worker to communicate with family and friends back in his home village. The family and friends he left behind likely only have access to a public telephone. So, even if the migrant worker finds a public telephone while on his journey, or is fortunate enough to have access to a mobile telephone along the way, he would still have no way of verbally communicating with his loved one unless he was somehow able to coordinate with his loved one to be at a local public pay telephone at a predetermined time.
Therefore, what is needed in the art is a community messaging service that provides a means for users to leave a voice message on a public telephone network such that the message can be retrieved at a later time by a specified subscriber.
Community Messaging Service (CMS) is a system and method for operators in developing countries to provide a messaging service to subscribers who cannot yet afford a wireless telephone or personal landline service, but have the basic requirement to communicate with each other. CMS makes it possible for callers to leave messages for people who would otherwise be unreachable and allow subscribers to reply back to those callers. More specifically, CMS involves the use of a pre-paid account to allow callers without telephones to have a non-gsm telephone number that can be used for communication via voicemail over a Public Switched Telephone Network (PSTN).
In a typical embodiment, a subscriber to CMS is assigned a number that he may distribute to co-workers, family and friends so that a caller can dial the number and directly leave a message for the subscriber that can be retrieved at a later time. The subscriber can call the service via a public pay telephone or a friend's telephone in order to retrieve the messages, and reply or dial out using prepaid airtime.
One embodiment of the present invention includes a messaging service that is available to a subscriber by providing the subscriber with a functional telephone number for calling parties to use; however, atypical to standard functional telephone numbers, this number is not associated with a standard terminating device. Rather than being terminated as a standard call, calls to the number assigned to a subscriber are terminated by a messaging system and callers are prompted to leave a message for the subscriber. More specifically, two types of calls may be received by the system. A first type of call is from a non-subscriber to the subscriber. In response to such a call, the call is terminated by the messaging system and the calling party is prompted to leave a message. The message is then recorded and stored in a storage device.
A second type of call is one that is from a subscriber. In some embodiments, a separate number may be used by the subscriber. However, in other embodiments, the same number may be used and the subscriber can access features of the messaging system by entering an access code when the call is terminated. In either case, when the call from the subscriber is terminated, and the subscriber gains access to the system, a status message is rendered to the subscriber to indicate the presence of voice messages. In response to the subscriber providing a request for a message, the system renders or plays back a message that was previously stored for the subscriber.
In other embodiments, during a subscriber call to the system, the subscriber can initiate a call over a telephone network to a telephone number identified by the subscriber or associated with an available message. Certain embodiments may result in debiting or charging the subscribers account in response to such call initiation. In yet other embodiments, rather than initiating a call, the subscriber may simply initiate the delivery of a voice message to another party. The system can then autonomously attempt the delivery of the message to an identified destination. The message may be delivered by rendering a voice message to an answering party, rendering a voice message to a voice messaging server for the intended party, converting the voice message to text and emailing the message or rendering the converted message to a facsimile machine, or using another method depending on the various embodiments of the invention.
A full and enabling disclosure of various embodiments of the present invention, including the best mode thereof is set forth in this specification which makes reference to the appended figures in which:
Various embodiments of the present invention, along with aspects and features thereof, provide a solution to the above-described needs in the art, as well as other needs in the art by providing a subscriber with the means by which voice messages may be deposited and retrieved over a public switched telephone network without requiring the subscriber to carry a telephone device or employ a cellular telephone with GSM (global system for mobile communications) capability.
Turning now to the drawings in which like labels represent like elements throughout the drawings, various aspects, features and embodiments of the present invention will be presented in more detail. The examples set forth in the drawings and the detailed description are provided by way of explanation of the invention and are not meant as limitations of the invention. The present invention thus includes any modifications and variations of the following examples as come within the scope of the appended claims and their equivalents.
In one embodiment of the present invention, a subscriber 10 to the CMS service places a call via a public telephone to a predetermined non-GMS telephone number. As is typical of calls placed on the PSTN, the call is transported in the Signaling System 7 (SS7) protocol and directed through the PSTN 80 to a Signaling Gateway 70. The Signaling Gateway 70 converts the SS7 data into SIGTRAN, the standard telephony protocol used to convert and forward SS7 signals over the Internet. From this point, the subscriber's 10 call data is forwarded to a media application server 60 used to run the CMS Telephony User Interface (TUI) application. The media application server 60 is a component of a local provisioning network 40 that includes various database servers 50, 90 and at least one System Management Unit 30. In processing the subscriber request to retrieve voice mail previously left for him by a user 20, or initiate some other task, the media application server 60 may communicate via an internet protocol over the local provisioning network 40 to call for applets running on any of the various other database servers. For example, functions such as subscriber profile verification, message storage and retrieval, personal greeting or spoken name playback, voucher management, account debiting, etc. may reside in a slave server on the Provisioning Network 40 such as the Next Generation Message Store database server 90 or the Charging Function database server 50 depicted in
It should be appreciated that
It should be appreciated that a Subscriber Identification Module (SIM) based approach and a SIM-less based approach are two broad design approaches that can be used to support CMS embodiments. Novel aspects and features of CMS are not limited by the choice or combination of various system component technologies. Even so, while each approach has advantages and disadvantages, the SIM-less based CMS embodiment advantageously is more cost-wise efficient, provides a more simple and intuitive user experience, and allows for flexible billing integration. Additionally, a SIM-less based approach is more easily branded, customized, and progressively extended to support additional services than a CMS embodiment that makes use of SIM enabled devices. Advantageously, a CMS that uses SIM-less components would, obviously, not require the distribution of SIM cards to subscribers. Rather, nothing more complicated than a coin operated pay telephone connected to the PSTN would be required in order for a subscriber to make use of his non-GSM telephone number and access code to check voicemail.
Turning now to
At any time after initial configuration, a subscriber 10 may change his account preferences (
Once the account is configured, a subscriber 10 may give his subscriber assigned telephone number to any person with whom he may want to communicate via the CMS. That person is herein referred to as the user 20 depicted in
In some embodiments, emails can be directed to the subscriber's telephone number and received by the CMS system and stored for retrieval. For instance, the CMS system can convert a received email from text into voice and make the message available for retrieval. Similarly, the CMS system can receive a faxed message and convert, as much as possible through optical character recognition techniques, the text to a voice mail message that can be retrieved by the subscriber. It should be noted that advantageously, this system is implemented without the subscriber having to subscribe to normal telephone service. For instance, the subscriber is able to access this functionality without having a landline run to his or her residence, or without even having to have a permanent residence. In addition, the subscriber is not required to purchase and obtain a mobile telephone device, such as a mobile telephone or cellular telephone. The telephone number assigned to a subscriber does not terminate on any end user equipment but, rather, terminates solely at the provisioning network 40. Messages directed towards the subscriber's telephone number are routed to the provisioning network 40 and the SMU 30, in cooperation with the media application server 60, prompts for, receives and stores within the next generation message store 90 any messages directed towards the user.
In another embodiment, the CMS system may allow a subscriber to record a message to be forwarded to another party. For instance, if a subscriber wishes to respond to a message or simply deliver a message to another CMS or non-CMS subscribing party, embodiments of the CMS system can facilitate this. The CMS system allows a subscriber to place a call to the CMS system and then during that call, allows the subscriber to record a message and then provide a destination address, such as a telephone number, email address, facsimile number, etc., for that message. Once the subscriber is completed and the subscriber call is terminated (or in some embodiments even before the subscriber call is terminated), the CMS can then attempt to deliver the message over a fixed period of time or indefinitely. Advantageously, this aspect or feature of embodiments of the invention enable a subscriber that does not own or possess his or her own terminating device to initiate the delivery of a message when they have access to a telephone device but, not require the subscriber to actually remain in the proximity of the telephone device until the intended party is contacted or the message is delivered. Utilizing this aspect, the CMS system can deliver voice messages recorded by the subscriber directly to an intended party by placing a call to a received telephone number and actually being connected to the intended party. The CMS system can also facilitate the delivery of the message by detecting an answer of a call by a voice mail system and then delivering the recorded message to the intended party's voice mail. If the subscriber provides the CMS system with a facsimile number, the CMS system can convert the voice message into a facsimile message and delivery the facsimile to the provided number. Further, if the destination information is an email address, the CMS system can convert the recorded message into text and route the message to the provided email address. It will also be appreciated that a text message or SMS message may be delivered if the provided destination information supports such messaging types.
In order to retrieve a message (
From the user menu 350, a subscriber 10 may choose to “dial out” (
In addition to retrieving messages and placing outgoing calls to other subscribers, a subscriber 10 may recharge the credit balance on his account (
Subsequent to this time, the CMS 95 is then available for third parties 20 to leave messages for the subscriber 10. It should also be appreciated that the subscriber can repeat the configuration process after the initial configuration process to change, modify or augment the operation of the CMS 95. The third party provides a message to the subscriber 10 by placing a call to the subscriber using a number specifically assigned to the subscriber 708. It should be appreciated that the number called by the third party 20 may also be a common or shared number and, to specifically access or direct a message to the subscriber, the third party may be required to enter an identification or redirection code. Once the call from the third party 20 is terminated by the CMS 95, the CMS 95 prompts the third party to leave a message 710. The message is then delivered to the CMS 95712 and the CMS 95 stores the message for the subscriber 714.
The subscriber 10, at any time, may place an access call to the CMS 95. Subsequent to a message being left for the subscriber 10, if the subscriber 10 places an access call 716, the CMS 95 will respond with a status message 718 indicating that one or more messages have been received. The subscriber 10 can request the playback of a message 720 which results in the CMS 95 rendering a message 722 to the subscriber 10. In addition, or in lieu of requesting a message playback, the subscriber 10 may also request a call to a third party 724, to which the CMS 95 will respond by initiating the call 726 and, in some embodiments, charging the subscriber 10 for the service. Furthermore, the subscriber 10 may also in addition or in lieu of, request a message to be delivered to a third party 728. In response to this request, the CMS 95 then prompts the subscriber 10 for the message 730 and also prompts for the destination identification for the message 732. The subscriber 10 responds to these prompts respectively by providing and/or selecting a message 734 and a destination 736. The CMS 95 then converts the message 738 as necessary and initiates or delivers the message to the identified destination 740.
