A METHOD FOR IMPLEMENTING SPEECH CHANNEL EXCHANGE IN THE CALL SUCCESSION OF THE MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a method for implementing voice channel switching during calling proceeding in a mobile communication system, comprising the steps of: adding a switching network in a Base Station Controller (BSC); authenticating the calling mobile station, determining the location area of the called mobile station and initiating paging for the called mobile station by the mobile communication system; obtaining the information of the coverage area of the Base Transceiver Station (BTS) corresponding to the calling mobile station and that of the BTS corresponding to the called mobile station, and judging whether the calling party and the called party locate in the coverage areas of the BTSs managed by the same BSC; if so, implementing voice channel connection through the switching network added in the BSC; otherwise implementing the voice channel connection through mobile exchanges. With this invention, roundabout voice paths can be reduced, meanwhile data flow and transmission delay between subsystems of the mobile system can be decreased.
