Communication controller, base station controller and communication system

DETAILED DESCRIPTION Taking the above into consideration, it is an object of the present invention to provide a communication controller that employs a connection control of roaming in WLL and provides communication services by efficiently making a connection even when the subscriber changes the area.
Another object of the present invention is to provide a base station controller that employs a connection control of roaming in WLL and provides communication services by efficiently making a connection even when the subscriber changes the area.
A further object of the present invention is to provide a communication system that employs a connection control of roaming in WLL and provides communication services by efficiently making a connection even when the subscriber changes the area.
The above objects of the present invention are achieved by a communication controller performing a connection control of roaming in which a subscriber terminal moves from a home area to a roaming area, said communication controller comprising: identification number management unit which 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; and call connection processing unit which translates the home area identification number and the roaming area identification number into each other for call connection processing.
The above and other objects, features and advantages of the present invention will become apparent from the following description when taken in conjunction with the accompanying drawings which illustrate preferred embodiments of the present invention by way of example.
