The terminal side can acquire whether the network side uses the narrow bandwidth technology, and automatically adjust a bandwidth of a corresponding channel at the terminal side when the network side uses the narrow bandwidth technology, so that intra-system performance loss and inter-system interference that are caused by different bandwidth modes between the terminal side and the network side are avoided, thus improving performance of a communication system.

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.
