Abstract

A method, system and computer program product for establishing communication services using web service operations over a network is presented. An application session can be established, extended and terminated between an event source and an event sink across the network by way of a session service. An addressing service on at least one of said event sink and said event source is used to address services. A multimedia communication services between the event source and the event sink is established by way of an eventing service.

Claims

1. A method of establishing communication services using web service operations over a network comprising:

establishing an application session association between two communication endpoints across the network by way of a session service, and wherein said application session includes web services which are used as meta-services to provide a service oriented extension framework to bundle base services and include new services in communications;

addressing services on at least one of said communication endpoints by way of an addressing service;

establishing and negotiating a media transmission relation between the two communication endpoints by way of an eventing service such that media at a first endpoint is exposed as a event source service and a second endpoint subscribes to receive events from said event source service and provides an event sink to said event source, wherein said session service, addressing service and eventing service are arranged in a single stack protocol, wherein said single stack protocol is specified by web service Web Service Description Language (WSDLs) and eXtensible Markup Language (XML) schemas;

controlling a media transmission relation between the event sink and the event source by way of an event subscription manager service that is communicated back to an event subscriber by the event source in its acknowledgement message of an event subscription; and

transmitting media data between the event source and the event sink by way of a transport protocol which is separate from said application session, and wherein communications signaling is entirely based on two-way web services interactions.

2. The method of claim 1 wherein said establishing a media transmission relation between the event source and the event sink by way of an eventing service includes an event source for generating events and accepting subscriptions.

3. The method of claim 1 wherein said establishing a media transmission relation between the event source and the event sink by way of an eventing service includes the event sink receiving event from the event source.

4. The method of claim 1 wherein said establishing a media transmission relation between the event source and the event sink by way of an eventing service includes a subscriber for subscribing to event sources on behalf of an event sink.

5. The method of claim 1 wherein said establishing a relation between the event source and the event sink by way of an eventing service includes a subscription manager for managing subscriptions.

6. The method of claim 1 further comprising extending said communication services to allow peer-to-peer communication.

7. The method of claim 1 wherein said negotiating a media transmission is Web Service based through two-way Web Services interaction by finding matching event source and event sink pairs between two web service endpoints.

8. The method of claim 1 wherein said establishing communication services includes establishing end-to-end message level security.

9. The method of claim 1 wherein said communications is accomplished using web service transaction messages between said event source and said event sink.

10. The method of claim 1 wherein media negotiation is totally Web Services based through two-way Web Services interaction of finding matching event sink-source between two Web Services endpoints, and wherein application session established Web Services are used as meta-services to provide a service oriented extension framework to bundle base services and include new services in communication.

11. The method of claim 1 wherein Web Services is used as a transport protocol to establish communications between said first endpoint and said second endpoint for real-time voice, video, multimedia and converged communication.

12. A non-transitory computer readable storage medium having computer readable code thereon for establishing communication services using web service operations over a network, the medium comprising:

instructions for establishing an application session association between two communication endpoints across the network by way of a session service, and wherein said application session includes web services which are used as meta-services to provide a service oriented extension framework to bundle base services and include new services in communications;

instructions for addressing services on at least one of said communication endpoints by way of an addressing service, wherein said session service, addressing service and eventing service are arranged in a single stack protocol, wherein said single stack protocol is specified by web service Web Service Description Language (WSDLs) and eXtensible Markup Language (XML) schemas;

instructions for establishing and negotiating a media transmission relation between the two communication endpoints by way of an eventing service such that media at a first endpoint is exposed as a event source service and a second endpoint subscribes to receive events from said event source service and provides an event sink to said event source;

instructions for controlling a media transmission relation between the event sink and the event source by way of an event subscription manager service that is communicated back to an event subscriber by the event source in its acknowledgement message of an event subscription; and

instructions for transmitting media data between the event source and the event sink by way of a transport protocol which is separate from said application session, and wherein communications signaling is entirely based on two-way web services interactions.

13. The computer readable medium of claim 12 wherein said instructions for establishing a media transmission relation between the event source and the event sink by way of an eventing service includes instructions for an event source for generating events and accepting subscriptions.

14. The computer readable medium of claim 12 wherein said instructions for establishing a media transmission relation between the event source and the event sink by way of an eventing service includes instructions for the event sink receiving event from the event source.

15. The computer readable medium of claim 12 wherein said instructions for establishing a media transmission relation between the event source and the event sink by way of an eventing service includes instructions for a subscriber for subscribing to event sources on behalf of an event sink.

16. The computer readable medium of claim 12 wherein said instructions for establishing a relation between the event source and the event sink by way of an eventing service includes instructions for a subscription manager for managing subscriptions.

17. The computer readable medium of claim 12 further comprising instructions for extending said communication services to allow peer-to-peer communication.

18. The computer readable medium of claim 12 wherein said instructions for negotiating a media transmission is Web Service based through two-way Web Services interaction by finding matching event source and event sink pairs between two web service endpoints.

19. The computer readable medium of claim 12 wherein said instructions for establishing communication services includes instructions for establishing end-to-end message level security.

20. The computer readable medium of claim 12 further comprising instructions wherein said communications is accomplished using web service transaction messages between said event source and said event sink.

21. The computer readable medium of claim 12 further comprising instructions wherein media negotiation is totally Web Services based through two-way Web Services interaction of finding matching event sink-source between two Web Services endpoints, and wherein application session established Web Services are used as meta-services to provide a service oriented extension framework to bundle base services and include new services in communication.

22. The computer readable storage medium of claim 12 further comprising instructions wherein Web Services is used as a transport protocol to establish communications between said first endpoint and said second endpoint for real-time voice, video, multimedia and converged communication.
