摘要:
The present invention discloses a method for implementing local exchange for a local call, including: a calling side mobile switch center (MSC) receiving a call setup request from a calling user, and the calling side MSC transferring a local reference to a calling side base station system (BSS) and a called side MSC, and transferring a calling access location information to the called side MSC; the called side MSC receiving the local reference and transferring the local reference to a called side BSS; and the called side MSC determining that a call is a local call according to the calling access information, and notifying the called side BSS to execute the local exchange. The present invention solves the problem that the local exchange is unsuccessful caused by one BBS connecting a plurality of MSCs.
