Abstract

Embodiments of the present invention provide a method, system and computer program product for deploying and delivering composite services in an NGN network. A method for auto-establishing a voice channel of access to a session for a composite service can include establishing a visual channel of access to a session for a composite service. Responsive to detecting a user interface event in a view for the visual channel which is not related to the establishment of a new channel of access, a separate voice channel of access to the session can be auto-established for the composite service. For instance, the user interface event can include the loading of a page for the view, the receipt of focus for a form in the view, the receipt of focus for a field in a form in the view, or a keystroke or mouse event. Finally, the method can include synchronizing changes of state for the session in a view for each of the visual channel of access and the voice channel of access to the session for the composite service.

Claims

1. A method for auto-establishing a voice channel of access to a session for a composite service, the method comprising:

2. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, comprises auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a load page event for the view in the visual channel.

3. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, comprises auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a focus event for a form in the view in the visual channel.

4. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, comprises auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a focus event for a field in a form in the view in the visual channel.

5. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, comprises auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a keystroke event for a field in a form in the view in the visual channel.

6. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, comprises auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a mouse event for a field in a form in the view in the visual channel.

7. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, further comprises:

retrieving a user configuration for auto-establishing a separate voice channel of access to the session for the composite service; and

,

auto-establishing a separate voice channel of access to the session for the composite service responsive to detecting a keystroke event for a field in a form in the view in the visual channel only if permitted by the user configuration.

8. The method of claim 1, wherein auto-establishing a separate voice channel of access to the session for the composite service, further comprises:

determining a telephone number from the request; and

,

forwarding a session initiating protocol (SIP) request to a voice enabler to dial out to the telephone number in order to establish the voice channel of access to the session.

9. The method of claim 1, wherein synchronizing changes of state for the session in a view for each of the channels of access to the service, comprises:

maintaining the state in a model for the session;

creating listeners for changes of the state in the model for each of the voice channel of access and the visual channel of access;

detecting changes in the state in the model in the listeners; and

,

updating the view for each of the voice channel of access and the visual channel of access to the session responsive to detecting the changes of state for the model in the listeners.

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, at least one of the channel servlets comprising a voice enabler;

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;

at least one of the views for a visual channel of access for the common session comprising trigger logic enabled to provide to the voice enabler a request to establish a voice channel of access for the common session responsive to detecting a user interface event not related to establishing a new channel of access for the common session.

11. The system of claim 11, 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 auto-establishing a voice channel of access to a session for a composite service, the computer program product including:
