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 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 method a device and a system for call handover and call processing. The method for call handover includes the following steps. An add endpoint request message is sent to a media gateway (MGW) in which the add endpoint request message carries endpoint information about a Time Division Multiple (TDM) type and codec information that corresponds to the TDM type and endpoint information about an Internet Protocol (IP) type and codec information that corresponds to the IP type. An add endpoint reply message indicating that the MGW successfully establishes a TDM endpoint and an IP endpoint is received and a Handover Request message carrying a circuit identifier code (CIC) information element and the endpoint information about an IP type is sent to a target Base Station Controller (BSC).; A Handover Request Acknowledge message carrying the endpoint information about a TDM type or the endpoint information about an IP type returned by the target BSC is received. A call failure case caused by different between TDM endpoints individually assigned by the target BSC and a core network (CN) side can be prevented thereby increasing a call success rate.
