Description

technical field

[0001] The invention relates to IP-based multimedia subsystem (IMS) technology, especially a method and system for improving service reliability. Background technique

[0002] During an initial service request triggering process on the IMS network, the serving call session control network element (S-CSCF) will match the initial filter criterion (IFC) in the user subscription information according to the received user's initial service request message, and will match The received initial service request messages are sequentially triggered to different application servers (AS), and then different types of services are provided to users through different ASs.

[0003] There are many types of initial service request messages, such as session initial service request messages for session services, subscription initial service request messages for subscription services, and registration initial service request messages for third-party registration. Since the S-CSCF...
