METHOD AND SYSTEM FOR LOCAL EXCHANGE COMMUNICATION

摘要

The present invention discloses a method for local exchange communication to simplify the transmission procedure of voice data in the communication system, which includes the following steps: the first and second base station perform signaling interaction with the corresponding base station controllers(BSC) respectively to establish the first corresponding communication channel, wherein, said BSCs obtain the communication information of the first and second base station in the signaling interaction process; the BSC corresponding to the first base station sends the communication information of the second base station to the first base station, and the BSC corresponding to the second base station sends the communication information of the first base station to the second base station; and the first base station establishes the second communication channel with the second base station through Internet Protocol network according to the communication information of the first and second base station, and releases the first communication channel. In addition, the present invention also discloses a local exchange communication system.
