PURPOSE:To accurately grasp the state that a mobile station is not moving across zones by allowing a base station to implement transmission power control and allowing the mobile station to measure and compare a reception electric field level of the base station during communication and a reception electric field level of peripheral base stations. CONSTITUTION:A mobile station 101 measures a reception electric field level of a base station 102 during communication and a reception electric field level of peripheral zones and sends the result of measurement to the base station as transmission information and the base station 102 during communication obtains correction information from an electric field level of a radio channel during communication based on the transmission information from the mobile station 101 and the base station 102 sends the correction information to the mobile station 101. The mobile station 101 receiving the correction information corrects the reception electric field level of the radio channel during communication and compares the electric field level after the correction with the reception electric field level of the peripheral zone and moves across zones when the reception electric field level of the peripheral zone is higher but does not move across zone when the reception electric field level of the peripheral zone is higher. Thus, a resident zone of the mobile station is accurately discriminated.
