Abstract :
To deliver the advanced services in IP multimedia subsystem (IMS), composition of many services including the session initial protocol (SIP) services is needed. However, IMS standard does not specify properly the architecture for SIP based service composition. Better performance and different user experience can be achieved in the SIP service composition for the real time communication services. We propose a modified IMS architecture by adding new functional entities: service enabler gateway (SEG) and application server (AS) for the SIP based service composition. We choose Java specification request (JSR) 289 AS for implementing service compositions service. This paper describes the SEG which implements the authorization and service discovery for IMS services.
