Abstract

A composite service enabling data processing system utilizing lightweight messaging can include channel servlets enabled to establish multiple, different channels of access to a common session for a composite service. The system also can include a location registry including a table of entries associating the different channels of access with the common session for the composite service. The system yet further can include a model servlet configured for coupling to a model for the common session, for modifying state data in the model for the common session, and to synchronize views for each of the different channels of access to the common session responsive to changes detected in the model. Finally, the system can include a lightweight messenger coupled to a selected one of the channel servlets and configured to transmit lightweight messages encapsulating changes to the model to a companion lightweight messenger in an end point for a channel of access to the common session established by the selected one of the channel servlets.

Claims

1. A composite service enabling data processing system comprising:

a plurality of channel servlets enabled to establish multiple different channels of access to a common session for a composite service;

a location registry comprising a table of entries associating the different channels of access with the common session for the composite service;

a model servlet configured for coupling to a model for the common session, for modifying state data in the model for the common session, and to synchronize views for each of the different channels of access to the common session responsive to changes detected in the model; and

,

a lightweight messenger coupled to a selected one of the channel servlets and configured to transmit lightweight messages encapsulating changes to the model to a companion lightweight messenger in an endpoint for a channel of access to the common session established by the selected one of the channel servlets.

2. The system of claim 1, wherein the channel servlets comprise a voice enabler and voice server enabled to establish a voice channel of access to the common session for the composite service.

3. The system of claim 1, wherein the channel servlets and model servlet are disposed in an application server.

4. The system of claim 1, wherein the channel servlets and model servlet are disposed in an Internet protocol (IP) multimedia subsystem (IMS) in a next generation networking (NGN) network.

5. The system of claim 1, wherein the lightweight messenger and the companion lightweight messenger implement the Blocks Extensible Exchange Protocol (BEEP).

6. A composite services enablement method comprising:

establishing multiple, different channels of access to a common session for a composite service;

lightweight messaging a change of state in a model for the common session over one of the channels of access for a corresponding view; and

,

updating the corresponding view with the change of state.

7. The method of claim 6, wherein establishing multiple, different channels of access to a common session for a composite service, comprises establishing at least a visual channel of access to the common session, and a voice channel of access to the common session.

8. The method of claim 6, wherein establishing multiple, different channels of access to a common session for a composite service, comprises establishing for a common session in a next generation networking (NGN) network at least a voice channel of access to the common session, and a visual channel of access to the common session.

9. The method of claim 6, wherein lightweight messaging a change of state in the model for the common session over one of the channels of access for a corresponding view, comprises:

maintaining the state of the model for the common session;

creating listeners for changes of the state for the model;

detecting a change in the state for the model in the listeners;

encapsulating the change of state in a lightweight message; and

,

forwarding the lightweight message to the corresponding view.

10. The method of claim 9, wherein forwarding the lightweight message to the corresponding view comprises forwarding the lightweight message to the corresponding view utilizing the lightweight messenger and the companion lightweight messenger over the Blocks Extensible Exchange Protocol (BEEP).

11. A computer program product comprising a computer usable medium having computer usable program code for composite services enablement, the computer program product including:

computer usable program code for establishing multiple, different channels of access to a common session for a composite service;

computer usable program code for lightweight messaging a change of state in a model for the common session over one of the channels of access for a corresponding view; and

,

computer usable program code for updating the corresponding view with the change of state.

12. The computer program product of claim 11, wherein the computer usable program code for establishing multiple, different channels of access to a common session for a composite service, comprises computer usable program code for establishing for the common session at least a visual channel of access to the common session, and a voice channel of access to the common session.

13. The computer program product of claim 11, wherein the computer usable program code for establishing multiple, different channels of access to a common session for a composite service, comprises computer usable program code for establishing for a common session in a next generation networking (NGN) network at least a visual channel of access to the common session, and a voice channel of access to the common session.

14. The computer program product of claim 11, wherein the computer usable program code for lightweight messaging a change of state in the model for the common session over one of the multiple, different channels of access for a corresponding view, comprises:

computer usable program code for maintaining the state in a model for the common session;

computer usable program code for creating listeners for changes of the state for the model;

computer usable program code for detecting a change in the state for the model in the listeners;

computer usable program code for encapsulating the change of state in a lightweight message; and

,

computer usable program code for forwarding the lightweight message to the corresponding view.

15. The computer program product of claim 14, wherein the computer usable program code for forwarding the lightweight message to the corresponding view comprises computer usable program code for forwarding the lightweight message to the corresponding view utilizing the lightweight messenger and the companion lightweight messenger over the Blocks Extensible Exchange Protocol (BEEP).
