Patent ID: 8189534

Claim:
A base station controller (BSC), connected between several BTSs (Base Transceiver Station) and a TC (Transcoder) under TDM (Time Division Multiplexing) mode, IP/TDM hybrid mode and IP (Internet Protocol) mode, respectively, characterized by comprising an IP/TDM mode call link controller based on a base station controller body, a first signaling interface controller and a second signaling interface controller each being connected with the IP/TDM mode call link controller, and an IP package forwarding unit, wherein the IP/TDM mode call link controller is used for processing setup, handover and releasing of voice and data call links during IP transmission or IP/TDM hybrid transmission; the first signaling interface controller is used for processing signaling transmission with the TC, controlling setup and releasing of switch links between voice channels at Ater interfaces and voice channels at A interfaces inside the TC; the second signaling interface controller is used for processing signaling and voice transmission with the BTSs and in IP, TDM or IP/TDM hybrid mode, and controlling setup and releasing of voice channels between the BTSs and the TC in IP mode or IP/TDM hybrid mode; the IP package forwarding unit is responsible for forwarding IP packages.
