  • Publication number: 20120155457
    Abstract: A multi-session transfer method, a call control device, and a Service Continuity and Continuity Application Server are disclosed. In the embodiments of the present invention, in a multi-session cross-network transfer process, if a second session to be transferred includes video media, a Mobile Switching Center (MSC) server judges capabilities of a current network. If the current network is incapable of transmitting video media, the MSC server sends a request for transferring voice media of the second session to be transferred. The SCC AS receives the transfer request, and converts the second session to be transferred into voice session for transferring or releases the second session to be transferred, and therefore, the problem in the prior art of incapability of transferring the session is avoided, and the cross-network multi-session service transfer is improved.
