Station usage status information is acquired (Sb10). Next, the base station resource control unit 15 determines the base station of the radio system A-1 according to the resources of the autonomous adaptive integrated base station 1 managed by the free resource management table 16 in the base station for each radio system.

When the base station cannot be reduced because the traffic volume has not decreased, the implementation for all the radio systems A-1 to A-N accommodated by the autonomous adaptive integrated base station 1 is performed. It is determined whether or not it is completed (Sb24). If it is not completed, the process returns to step Sb10, and the above-described processing is sequentially repeated for other radio systems. On the other hand, when the implementation for all the radio systems A-1 to A-N is completed, the processing is terminated.
