Abstract:
    The invention relates to a call building method under base station controller multi-attach network. Wherein, said method comprises: A, the caller sends inter-junction call, the caller mobile exchange center MSC obtains the called user position information in attach position register HLR, HLT detects that the MSC of caller and called users are belonging to same resource pool; HLR feedbacks response message to the caller MSC to redirect the service of caller MSC to called MSC; B, caller MSC starts service redirection, to send service redirection information to the base station controller BSC, carrying the mark of called MSC; caller BSC receives said service redirection message, based on its called MSC mark, to send call request to the called MSC; C, called MSC receives the call request of caller BSC to build internal junction call. The invention can make the common inter-junction call between different MSC in one resource pool into internal junction call, to save the inter-junction conversation resource.
