SYSTEM, METHOD AND BASE STATION FOR IMPLEMENTING LOCAL SWITCHING TRANSMISSION

摘要

The invention discloses a method, system and base station for implementing local switching transmission, the method including: after receiving a call service, if a Base Station Controller (BSC) determines, according to link information stored in a local switching group, that the source Base Transceiver Station (BTS) and destination BTS of said call service belong to the same local switching group, then the BSC notifies the source BTS and destination BTS to perform forwarding messages in the group; after receiving the notification of performing forwarding the messages in the group, said source BTS and destination BTS implement, according to the preconfigured data forwarding relation table, the forwarding of the messages related to said call service, or said source BTS and destination BTS cooperate with other related BTSs in the local switching group to implement, according to the preconfigured data forwarding relation table, the forwarding of the messages related to said call service. The present invention greatly saves transmission costs and improves voice quality.
