Method, user equipment and server for multimedia session transfer

摘要

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, sending the dynamic STI corresponding to the held CS session to the UE, 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.

1. A method for multimedia session transfer by a server, comprising:
receiving, by the server, a session transfer request sent by a User Equipment (UE), wherein the session transfer request carries a static Session Transfer Identifier (STI); executing, by the server, a procedure for transferring an active Circuit Switched CS) session according to the static STI; sending by the server, to the UE, a dynamic STI allocated to a held CS session during a session transfer; and receiving, by the server, another session transfer request sent by the UE, wherein the other session transfer request carries the dynamic STI sent to the UE during the session transfer; and executing, by the server, a procedure for transferring the held CS session according to the received other session transfer request carrying the dynamic STI.
