A mobile station includes an intermittent communication managing unit that manages a communication period for communicating with a first base station and a non-communication period for not communicating with the first base station, and a scan period setting unit that shifts and sets a scan period to reduce an overlap period with the communication period. The scan period, during which a scanning process for obtaining a condition of radio waves from a second base station can be executed, overlaps a plurality of the communication periods. Moreover, the mobile station includes a scan processor that executes the scanning process during the scan period.
