Method, system, and device for realizing registration mechanism of IP multimedia subsystem

摘要

The present invention provides a method, a device, and a system for realizing a registration mechanism of an IP multimedia subsystem. In the above method, a S-CSCF obtains a private user identity and a public user identity of CS UE and characteristic information of a MSC Server from a received request message, wherein the request message includes a registration request or a de-registration request; and then matches the obtained private user identity, public user identity, and characteristic information with existing registration binding relationships. If the match is successful, an operation indicated by said request message is performed on the successfully matched registration binding relationship. Based on the solution proposed in the present invention, the logic of the registration service can be ensured to be normal.

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.
