<p>An improved method for implementing reverse single radio voice call continuity comprises: an enhanced Mobile Switch Center (eMSC) obtains the signalling anchor point information distributed by an IP Multimedia Subsystem (IMS) network to a terminal to handover from Circuit Switch (CS) to Packet Switch (PS), after receiving from the terminal a handover request from CS to PS, the eMSC judges that the sigalling anchor point information distributed by the IMS network to the terminal to handover from CS to PS is not included in the sigalling path of a current session of the terminal, and then prevents the terminal from handing over from CS to PS.</p> |
