Abstract
There are provided a communication controller, a base station controller and a communication system that employs a connection control of roaming applied to WLL and efficiently makes a connection and continuously provides communication service even when a subscriber changes the area. An identification number management unit manages a home area identification number assigned to the subscriber terminal in the home area and a roaming area identification number assigned thereto in the roaming area. A call connection processing unit translates the home area identification number and the roaming area identification number into each other for call connection processing.
