ABSTRACT:
In a mobile communication system, a mobile communication switching center includes a communication restriction control section for calculating a communication channel usage from the traffic volume of communication channels, comparing the usage with first and second thresholds, and designating communication restriction on the basis of the comparison result, and a base station control section for creating first notification information indicating communication restriction on only the roaming mobile station or second notification information indicating communication restriction on all the mobile stations on the basis of an instruction from the communication restriction control section depending on whether it is determined that the calculated communication channel usage is higher than the first threshold but is not higher than the second threshold, or exceeds the second threshold, and transmitting control information including the pieces of first and second notification information to each of the mobile stations through the mobile communication switching center. Each of the mobile stations includes determination section for determining on the basis of the control information transmitted from the radio base station whether communication restriction is imposed on the mobile station.
