In view of the foregoing problems, the present application provides a method and an apparatus for multimedia subsystem migration, which can implement the migration of a multimedia subsystem in a scenario where a shared base station is not deployed independently.

The I-CSCF103 is the entry point to the home network of the IMS 102. During the registration process, the I-CSCF103 selects an S-CSCF105 for the user by querying the HSS 104. During a call, a call destined for the IMS102 network is first routed to the I-CSCF103, the I-CSCF103 obtains the S-SCSCF105 address from the HSS104, to which the user is registered, and routes the message to the S-CSCF 105.
The S-CSCF105, which is in the core position in the IMS102 network session control, accepts registration requests from the visited network forwarded via the I-CSCF103 and cooperates with the HSS104 for user authentication. And downloads the service data subscribed to by the user from the HSS 104. The S-CSCF105 performs routing management on the calling and called sides of the user, and performs session initiation protocol application service (SIP AS) triggering according to an initial filtering rule signed by the user, thereby implementing a rich IMS service function.
The local private network 02 includes a UE106, a private network RAN107, a private network 5G core network (5GC)108, a private network PCF109, and a private network IMS 110.
