Abstract:
1. A method for realizing an IMS registration mechanism of an IP multimedia subsystem, applied to a network environment of a CS User Equipment (CS UE), an Enhanced Mobile Switching Center Server (MSC Server), and an IMS, wherein when the MSC Server replaces the CS UE to send a registration or de-registration request to the IMS, the method comprises: a Serving Call Session Control Function (S-CSCF) of the IMS obtaining a private user identity and a public user identity of the CS UE and characteristic information of the MSC Server from a received request message, wherein the request message includes a registration request or a de-registration request; the S-CSCF matching the obtained private user identity, public user identity, and characteristic information with existing registration binding relationships; and performing an operation indicated by the request message on the successfully matched registration binding relationship, if the match is successful.
