The present invention discloses a method, User Equipment (UE), and server for multimedia session transfer, and relates to a mobile communication technology, and in particular, to a technology for transferring multimedia sessions from a Circuit Switched (CS) network to a Packet Switched (PS) network. The method includes: receiving a session transfer request sent by a UE, where the session transfer request carries a static Session Transfer Identifier (STI); executing a procedure for transferring the active CS session according to the CS session transfer request, and judging whether the UE has a held CS session; and if so, sending the dynamic STI corresponding to the held CS session to the UE so that the UE can send a CS session transfer request again according to the dynamic STI, and receiving the request for transferring the held CS session and executing a procedure for transferring the held CS session. Further, a UE and a server are provided. With the present invention, two multimedia sessions in a CS network of the UE incapable of IMS Centralized Service (ICS) can be transferred to the PS network. |
