Feature: IMS Service Brokering enhancements

3GPP has adopted the approach of creating a number of IMS enablers that can be used by a number of services.  The success of this has been demonstrated through the adoption of the IMS by other standardisation bodies (e.g. TISPAN, OMA, ….).  Various technical IMS specifications provide the ability to sequence invocations of IP Multimedia Applications or their servers.  Being able to statically sequence handing off session control to individual applications or their servers is not sufficient. Use cases exist where applying only this static means would result in an undesirable service experience for the user.

This work item enhances existing requirements for the coordination of IP Multimedia Applications engaged in service delivery.

A means is required in order to identify the correct IP Multimedia Application (or its server) requested and to coordinate among applications for the following reasons:

    §         It is required to identify the correct IP Multimedia Application (server(s)) to link into the call path, if required, in order to provide a consistent & anticipated user experience.

    §         Often interworking requires knowledge of the services being interworked, as such interworking between an IMS based IP Multimedia Application and a non-IMS based service may benefit from the identification of the requested service.

Also, a means is required in order to store the Service Broker identifier sequencing instructions for application coordination.

The objective of the work item is to enhance functionality for service brokering found in previous releases.
