METHOD AND SYSTEM FOR PERFORMING A LOCAL SWITCHING OF A LOCAL CALL

摘要

A method for performing a local switching of a local call is provided in the present invention, which includes that: a source Mobile Switch Center (MSC) receives a switching request from a source Base Station System (BSS); the source MSC transfers a local reference to a destination BSS; and the destination BSS judges whether a local switching can be triggered according to the received local reference, and performs the local switching if the judgment result is that the local switching can be triggered. Also a system for performing a local switching of a local call is provided in the present invention, and includes an MSC and a BSS, wherein the MSC includes an MSC request module and an MSC processing module, and the BSS includes a BSS request module and a BSS processing module, to support the performance of the local switching of the local call in the scene of switching. The method and system provided in the present invention perform the local switching of the local call in the scene of switching, and resolve the problem of unsuccessful local switching due to the connection of a BSS to a plurality of MSCs.
