Abstract
A wireless local loop (WLL) base station controller includes a call control processor adapted to perform call control according to an internetworking operation system (IOS) protocol and to manage information generated during call processing. The WLL controller further includes a common channel signaling processor adapted to process and manage messages interchanged according to the IOS protocol between the call control processor and mobile switching center. Also included is an operation control processor adapted to perform inter-process communication with a common channel signaling processor to bypass an IOS-related message delivered from the call control processor to the mobile switching controller. The WLL controller can therefore be reconstructed to serve as a base station controller of a 3G mobile communication network for converting a currently working WLL network into a 3G mobile communication network.
