Abstract

Real-time service composition is provided by a Session Initiation Protocol (SIP) transport binding for Simple Object Access Protocol (SOAP) messages. A SOAPAction header and SOAP envelope can be included in a SIP message to identify a requested service. The SIP message recipient can parse out the SOAP envelope and forward same to a corresponding Web Service. An intermediary node, including a SIP Proxy, can evaluate incoming SIP/SOAP messages and provide requested services to which they have access. Service discovery and subscription are facilitated by adding Universal Description, Discovery and Integration (UDDI) services requests and responses.

Claims

1. A service subscription method comprising:

transmitting a Session Initiation Protocol (SIP) message including a Simple Object Access Protocol (SOAP) envelope and a SOAP action header, said SOAP action header indicating that said SIP message includes a Universal Description, Discovery and Integration (UDDI) service subscription request.

2. The method of claim 1, wherein said SIP message is a SIP SUBSCRIBE message.

3. The method of claim 1, wherein said SOAP envelope includes a UDDI save_binding request and save_subscription request in a SOAP body.

4. The method of claim 1, wherein said SOAP action header indicates an ultimate receiver of said SOAP envelope for which a service subscription is being requested.

5. The method of claim 1, further comprising the steps of:

receiving said transmitted SIP/SOAP message at an intermediary node including an Event Service; and

transmitting a SIP NOTIFY message toward an ultimate receive of said service subscription request.

6. The method of claim 5, further comprising the steps of:

parsing the SIP/SOAP message; and

registering the service subscription request with a UDDI registry.

7. The method of claim 6, further comprising the step of:

transmitting a SIP/SOAP message informing a subscriber of new services.

8. The method of claim 7, wherein said SIP/SOAP message includes a SOAP envelope containing a UDDI notify_subscriptionListener request in a SOAP body.

9. A computer-readable medium containing instructions which, when executed on a processor, perform the steps of:

transmitting a Session Initiation Protocol (SIP) message including a Simple Object Access Protocol (SOAP) envelope and a SOAP action header, said SOAP action header indicating that said SIP message includes a Universal Description, Discovery and Integration (UDDI) service subscription request.

10. The computer-readable medium of claim 9, wherein said SIP message is a SIP SUBSCRIBE message.

11. The computer-readable medium of claim 9, wherein said SOAP envelope includes a UDDI save binding request and save_subscription request in a SOAP body.

12. The computer-readable medium of claim 9, wherein said SOAP action header indicates an ultimate receiver of said SOAP envelope for which a service subscription is being requested.

13. The computer-readable medium of claim 9, further comprising the steps of:

receiving said transmitted SIP/SOAP message at an intermediary node including an Event Service; and

transmitting a SIP NOTIFY message toward an ultimate receive of said service subscription request.

14. The computer-readable medium of claim 13, further comprising the steps of:

parsing the SIP/SOAP message; and

registering the service subscription request with a UDDI registry.

15. The computer-readable medium of claim 14, further comprising the step of:

transmitting a SIP/SOAP message informing a subscriber of new services.

16. The computer-readable medium of claim 15, wherein said SIP/SOAP message includes a SOAP envelope containing a UDDI notify_subscriptionListener request in a SOAP body.

17. A communications node comprising:

a processor operating as at least one of;

a SIP user agent server (UAS) and an Event Service, and which receives a first SIP message including a Simple Object Access Protocol (SOAP) envelope and a SOAP action header indicating that said SIP message includes a Universal Description, Discovery and Integration (UDDI) service subscription request,

wherein said processor sends, responsive to said first SIP message, a second SIP message toward an ultimate receiver of said UDDI service subscription request.

18. The communications node of claim 17, wherein said first SIP message is a SUBSCRIBE message and said second SIP message is a NOTIFY message.

19. A communications node comprising:

a processor operating as a watcher and as a SIP user agent server (UAS), which transmits a SIP message including a Simple Object Access Protocol (SOAP) envelope and a SOAP action header indicating that said SIP message includes a Universal Description, Discovery and Integration (UDDI) service subscription request.

20. The communications node of claim 19, wherein said SIP message is a SIP SUBSCRIBE message.

21. The communications node of claim 19, wherein said SOAP envelope includes a UDDI save_binding request and save_subscription request in a SOAP body.

22. The communications node of claim 19, wherein said SOAP action header indicates an ultimate receiver of said SOAP envelope for which a service subscription is being requested.
