Enabling Service Capability Interaction for Converged and Composite Services in IMS Networks

The promise of Converged Networks with all-IP interconnectivity comes closer to realization with the IP Multimedia subsystem (IMS) reference architecture. The salient feature of IMS that has helped it gain prominence is its capability as an infrastructure for exciting multimedia applications. IMS builds a powerful story with a combination of SIP based application servers and a flexible control architecture. The commonly followed schemes work well for proving single applications with the IMS architecture. The challenge is to harness multiple applications and provide a set of combined or blended services. This problem is gaining more exposure as we head towards fully functional IMS deployment and also to support competitive multimedia services from the Internet. 
 
The SCIM (Service Capability Interaction Manager) was initially conceived in the IMS standards but was not detailed enough. This poses a challenge to the core infrastructure and application vendors. Service providers see merit in this approach and are also beginning to view this as an answer to their problem of having several silos by having a common application/service launching platform.
