Abstract

An interactive media system for an IP Multimedia Subsystem (IMS) architecture includes a media resource function processor (MRFP) and a media resource function controller (MRFC). The MRFP includes media resources, such as automatic speech recognition (ASR) engines and text-to-speech (TTS) engines, and a voice browser. A caller places a call to a telephone number to reach an interactive media service, and the MRFC establishes a real-time packet media session between the media gateway and the MRFP. The voice browser queries a location server to determine the location of an interactive application associated with the called telephone number and then queries an application server corresponding to the location to obtain the interactive application as a voice extensible markup language (VXML) document. The browser interprets the VXML document and responsively invokes the media resources, via the MRFC, to provide the interactive media service to the caller.

Claims

1. An interactive media system for providing interactive media services to a caller during a call from said caller to a called telephone number, comprising:

a location server, said location server storing a location of an interactive application;

an application server, said application server storing, at said location, said interactive application in a predetermined format;

a media resource controller;

at least one media resource; and

a browser, said browser being configured to (i) receive said called telephone number, (ii) determine said location by sending said location server a request identifying said called telephone number, wherein said location server functions as a redirection server by identifying said location in response to said request, (iii) obtain said interactive application in said predetermined format from said application server by identifying said location, (iv) interpret said interactive application in said predetermined format and (v) responsively communicate with said media resource controller to invoke said at least one media resource in accordance with said interactive application.

2. The interactive media system of claim 1, wherein said browser and said at least one media resource are in a media resource processor.

3. The interactive media system of claim 1, wherein said at least one media resource includes at least one automatic speech recognition (ASR) engine.

4. The interactive media system of claim 1, wherein said at least one media resource includes at least one text-to-speech (TTS) engine.

5. The interactive media system of claim 1, wherein said predetermined format is a markup language.

6. The interactive media system of claim 1, wherein said browser is a voice browser and wherein said predetermined format is a voice extensible markup language (VXML).

11. The interactive media system of claim 1, wherein said location server identifies said location as a Universal Resource Locator (URL).

12. The interactive media system of claim 11, wherein said browser is configured to obtain said interactive application in said predetermined format from said application server by sending a HyperText Transfer Protocol (HTTP) GET request with said URL to said application server.

7. A method of providing an interactive media service, said method comprising:

a media resource processor receiving at least one call identifier;

said media resource processor receiving a location from a location server in response to a first request, said first request identifying said at least one call identifier;

said media resource processor receiving an interactive application from an application server in response to a second request, said second request identifying said location;

a media resource controller establishing a real-time packet media session with said media resource processor;

said media resource processor interpreting said interactive application and responsively sending messages to said media resource controller; and

said media resource controller controlling said media resource processor during said real-time packet media session in accordance with said messages.

8. The method of claim 7, wherein said at least one call identifier includes a called telephone number.

9. The method of claim 7, wherein said media resource controller controlling said media resource processor during said real-time packet media session in accordance with said messages comprises:

said media resource controller controlling an automatic speech recognition (ASR) engine of said media resource processor in accordance with said messages.

10. The method of claim 7, wherein said media resource controller controlling said media resource processor during said real-time packet media session in accordance with said messages comprises:

said media resource controller controlling a text-to-speech (TTS) engine of said media resource processor in accordance with said messages.
