Abstract
The embodiments of the present invention provide a method an apparatus and a system for call handover and process the method for call handover includes: sending an ADD.Req message to a media gateway wherein the ADD.Req message carries TDM type endpoint information and codec information corresponding to the TDM type and IP type endpoint information and codec information corresponding to the IP type; receiving an ADD.Reply message that indicates the media gateway establishes successfully the TDM endpoint and the IP endpoint sending an target base station controller BSC a Handover Request message carrying the circuit identifier code information element and the IP type endpoint information; receiving a Handover Request Acknowledge message carrying the TDM type endpoint information or the IP type endpoint information replied from the target BSC. The embodiments of the present invention can avoid the call failure event caused by the mismatch of the TDM endpoint individually assigned by the object BSC and a core network thus the call success rate is improved.
The embodiment of the invention claims a call handover processing method and device and system call switching method comprises the following steps: sending a TDM type endpoint information and encoding information corresponding to the TDM type. encoding information of endpoint additional request message and IP type endpoint information the IP type and corresponding to the media gateway receiving the indicating the media gateway to successfully establish the endpoint addition response message the TDM endpoint and the IP endpoint sending a handover request message of the circuit identification code cell and IP type endpoint information to a target base station controller; receiving the switching request acknowledgement message carrying TDM type endpoint information or IP type endpoint information returned by the target base station controller of the. The embodiment of the invention can avoid the target base station controller and a core network side independently assigned TDM endpoint does not match the call failure is caused which improves call success rate.
