A mobile station performs location registration to one of exchanges managing a location registration area where the mobile station is located, in a mobile communication system in which a plurality of exchanges manage one location registration area and a radio network controller is connected to the plurality of exchanges. The mobile station includes a communication controller configured to stop transmission of signals to the radio network controller, when an identifier of an exchange notified by an access restriction signal from the radio network controller matches an identifier of an exchange which has performed the location registration of the mobile station.
