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 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, processing a request from the visual channel of access to establish a voice channel of access to the session for the composite service, and 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 session. In one aspect of the embodiment, establishing a visual channel of access to a session for a composite service, further can include placing a hyperlink in the view for the visual channel of access to provide the request to establish the voice channel.

Claims

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

establishing a visual channel of access to a session for a composite service;

processing a request from the visual channel of access to establish a voice channel of access to the session for the composite service; and

,

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.

2. The method of claim 1, wherein establishing a visual channel of access to a session for a composite service, further comprises placing a hyperlink in the view for the visual channel of access to provide the request to establish the voice channel.

3. The method of claim 1, wherein processing a request from the visual channel of access to establish a voice channel of access to the session for the composite service, 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.

4. 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 session, 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.

5. 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 a hyperlink enabled to provide to the voice enabler a request to establish a voice channel of access for the common session.

6. The system of claim 5, wherein the channel servlets and model servlet are disposed in an application server.

7. The system of claim 5, wherein the channel servlets and model servlet are disposed in an Internet protocol (IP) multimedia subsystem (IMS) in a next generation networking (NGN) network.

8. A computer program product comprising a computer usable medium having computer usable program code for establishing a voice channel of access to a session for a composite service, the computer program product including:

computer usable program code for establishing a visual channel of access to a session for a composite service;

computer usable program code for processing a request from the visual channel of access to establish a voice channel of access to the session for the composite service; and

,

computer usable program code for 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 session.

9. The computer program product of claim 8, wherein the computer usable program code for establishing a visual channel of access to a session for a composite service, further comprises computer usable program code for placing a hyperlink in the view for the visual channel of access to provide the request to establish the voice channel.

10. The computer program product of claim 8, wherein the computer usable program code for processing a request from the visual channel of access to establish a voice channel of access to the session for the composite service, comprises:

computer usable program code for determining a telephone number from the request; and

,

computer usable program code for 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.

11. The computer program product of claim 8, wherein the computer usable program code for synchronizing changes of state for the service in a view for each of the channels of access to the services, comprises:

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

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

computer usable program code for detecting changes in the state in the model for the session in the listeners; and

,

computer usable program code for updating the view for each of the voice channel of access and the visual channel of access to the services responsive to detecting the changes of state in the model in the listeners.
