Connection destination session controller, IP multimedia subsystem, and session registration method in the system

摘要

A local session controller, an IP multimedia subsystem, and a session registration method are presented. The local session controller comprises: an information receiving module, a service initiating and configuring module, a session control module, and an information transmitting module. The IP multimedia subsystem mainly comprises the local session controller and a home subscriber server of the whole network. The local session controller initiates an authentication request during the session registration period, processes the request from the subscribers directly, and then establishes the session. The above scheme can make the signaling processing simply and reduce the complexity of the network.
