Abstract

Embodiments of the present invention provide a method, system and computer program product for deploying and delivering composite services in an NGN network. In one embodiment of the invention, an update notification method for peer views in a composite services enablement environment can include establishing multiple channels of access for a common session to a composite service and synchronizing updates to a model for the common session in each view for the channels of access. Importantly, the method can include detecting an impending update to the model in a view for one of the channels of access and providing a notification of the impending update to the model to others of the channels of access. For instance, detecting an impending update to the model in a view for one of the channels of access can include detecting a selection of a user interface element or editing of a field in the view for the one of the channels.

Claims

1. An update notification method for peer views in a composite services enablement environment, the method comprising:

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

synchronizing updates to a model for the common session in each view for the channels of access; and

,

detecting an impending update to the model in a view for one of the channels of access and providing a notification of the impending update to the model to others of the channels of access.

2. The method of claim 1, wherein establishing multiple channels of access for a common session to a composite service, comprises establishing for the common session at least a channel of access for voice mode of access to the service, and a channel of access for a visual mode of access to the service.

3. The method of claim 1, wherein establishing multiple channels of access for a common session to a composite service, comprises establishing multiple channels of access for a common session in a next generation networking (NGN) network for at least a channel of access for a voice mode of access to the service, and a channel of access for a visual mode of access to the service.

4. The method of claim 1, wherein synchronizing updates to a model for the common session in each view for the channels of access, comprises:

maintaining access to the model for the composite service;

creating listeners for updates to values for data members of the composite service;

detecting updates to the values for the data members in the listeners; and

,

providing the detected updates to each view for each of the channels of access.

5. The method of claim 1, wherein detecting an impending update to the model in a view for one of the channels of access, comprises detecting a selection of a user interface element in the view for the one of the channels.

6. The method of claim 1, wherein detecting an impending update to the model in a view for one of the channels of access, comprises detecting editing of a field in the view for the one of the channels.

7. The method of claim 1, wherein providing a notification of the impending update to the model to others of the channels of access, comprises lightweight messaging the notification to the others of the channels of access.

8. The method of claim 1, further comprising rendering an indicator of an update in process in a view receiving the notification.

9. The method of claim 1, further comprising rendering a window indicating an update in process in a view receiving the notification.

10. 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; and

,

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

,

update detection logic coupled to each of the views, the update detection logic comprising program code enabled to detect in one of the views impending updates to the model by others of the views and to render an indication of the impending updates in the one of the views.

11. The system of claim 10, wherein the channel servlets and model servlet are disposed in an Internet protocol (IP) multimedia subsystem (IMS) in a next generation networking (NGN) network.

12. A computer program product comprising a computer usable medium having computer usable program code for update notification for peer views in a composite services enablement environment, the computer program product including:

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

computer usable program code for synchronizing updates to a model for the common session in each view for the channels of access; and

,

computer usable program code for detecting an impending update to the model in a view for one of the channels of access and providing a notification of the impending update to the model to others of the channels of access.

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

14. The computer program product of claim 12, wherein the computer usable program code for establishing multiple channels of access for a common session to a composite service, comprises computer usable program code for establishing multiple channels of access for a common session in a next generation networking (NGN) network for at least a channel of access for a voice mode of access to the service, and a channel of access for a visual mode of access to the service.

15. The computer program product of claim 12, wherein the computer usable program code for synchronizing updates to a model for the common session in each view for the channels of access, comprises:

computer usable program code for maintaining access to the model for the composite service;

computer usable program code for creating listeners for updates to values for data members of the composite service;

computer usable program code for detecting updates to the values for the data members in the listeners; and

,

computer usable program code for providing the detected updates to each view for each of the channels of access.

16. The computer program product of claim 12, wherein the computer usable program code for detecting an impending update to the model in a view for one of the channels of access, comprises computer usable program code for detecting a selection of a user interface element in the view for the one of the channels.

17. The computer program product of claim 12, wherein the computer usable program code for detecting an impending update to the model in a view for one of the channels of access, comprises computer usable program code for detecting editing of a field in the view for the one of the channels.

18. The computer program product of claim 12, wherein the computer usable program code for providing a notification of the impending update to the model to others of the channels of access, comprises computer usable program code for lightweight messaging the notification to the others of the channels of access.

19. The computer program product of claim 12, further comprising computer usable program code for rendering an indicator of an update in process in a view receiving the notification.

20. The computer program product of claim 12, further comprising computer usable program code for rendering a window indicating an update in process in a view receiving the notification.
