Abstract
It is provided a mobile communication system comprising base stations, call control servers and access gateways. The call control servers cause a mobile terminal accommodated in one of the control server to transmit the location registration request so that the mobile terminal accommodates in another control server according to a processing amount of control signals. The base station selects a second call control server into which the one of the mobile terminals is to be newly accommodated. The one of the call control server switches to a power-saving state after the mobile terminal is accommodated into the another call control server.
