Small-sized base station controller providing flexible board design and controlling method thereof

摘要

A base station controller and method controlling the same wherein the base station can be small-sized in order that it is to be installed in a rack of a private base station and the number of boards installed in a backboard can be flexibly increased or decreased according to a subscriber capability, the small-sized base station controller providing a flexible board design, comprising: a Network Synchronization clock distribution Block (NSB) for generating a plurality of system synchronization clocks and network synchronization clocks using a synchronization clock received from a GPS satellite and distributing the clocks to each shelf in the base station; an Air Termination Processor (ATP) block to be used to match with a mobile terminal in a wireless environment; a TAB block (TransCord & ATM E1/T1 Link Block) having an ALB block (ATM E1/T1 Link Block) for providing an interface between networks and a TCB (TransCord Bank) block for processing a voice compression signal transmitted through a base station from the mobile terminal and PCM data transmitted to an exchange; and an MCB block (Main Control Block) for loading corresponding OSs (Operating Systems) with respect to the NSB block, ATP block and TAB block using backboard identifiers, and collecting switching of signals and all generated alarm signals.
