To enable a mobile station, when a base station carries out a measurement of a radio signal coming from an adjacent cell while suspending at least one of radio transmission to and radio reception from the mobile station when a base station's own cell is in operation, to recognize that the adjacent cell is being measured. A home base station 1 carries out a measurement of a radio signal coming from an adjacent cell while suspending at least one of radio transmission to and radio reception from a mobile station 3-1 when a base station's own cell (home cell) is in operation. Further, the home base station 1 notifies, prior to beginning the measurement, advance notice information indicating an execution of the measurement to the mobile station 3-1.
