Abstract
A method and system for implementing reverse Single Radio Voice Call Continuity (rSRVCC) are provided in the present invention. The method includes: after receiving a handover request from a Circuit Switch (CS) domain, a current Mobile Switch Center (MSC) sending a transfer request regarding a terminal subscriber or a session in which the terminal subscriber participates to an IP Multimedia Core Network Subsystem (IMS) Control Function Entity (ICFE); and after receiving the transfer request, the ICFE initiating a media connection establishment flow between the terminal and a far end. The technical solution of the present invention ensures rSRVCC when a terminal hands over from a CS domain to a PS domain.
