きる。In this way, the system monitoring unit 10 compares the number of processed calls of the communication control unit in a predetermined cycle T, and at that time, the first communication control unit 20i having the smallest number of processed calls has the largest number of processed calls. By substituting the call setup / call release processing of the second communication control unit 20j, the number of calls processed by each communication control unit is made uniform, and the occurrence of congestion in the communication control system can be suppressed.

On the contrary, the communication control unit 20i having the smallest number of processed calls becomes the maximum at the beginning, and eventually, the alternate processing is performed only between the two parties. On the other hand, if it is too short, the switching overhead only increases and the effect of load equalization is not desired. Therefore, it is preferable that the period T is set to, for example, about 1.5 to 2 times the average processing time according to the average processing time of call setup and call release per call.
