Abstract
Disclosed are an access session controller, an IP multimedia subsystem and registration and session establishment methods thereof, where the access session controller includes a message reception module, a service trigger configuration module, a session control module and a message transmission module. The IP multimedia subsystem includes the access session controller and a network-wide home subscriber server system. The registration method includes: initiating, by the access session controller, an authentication information request to the network-wide home subscriber server system. The session establishment method includes: directly process, by the access session controller, the request message initiated from a user to establish a session. The foregoing solutions can simplify the signaling processing flow and reduce the network complexity.
