PROBLEM TO BE SOLVED: To make the interference to the communication of another base station min. by judging the quantity of the radio wave of transmission output power in order to permit a mobile station to receive radio wave by means of fixed electric field strength and controlling the output of a transmitter in a communication slot where communication with the mobile station is executed. SOLUTION: A reception electric field data processing part 8 normally monitors the reception electric field strength of a control slot from the mobile station before communication between the base station 1 for mobile body communication and the mobile station is secured, monitors the reception electric field strength of the communication slot from the used mobile station when communication between the base station 1 for mobile body communication 1 and the mobile station is secured and transmits the numerical value to a base station control part 10. Moreover, the quantity of the radio wave of transmission power in order to receive radio wave by fixed electric field strength is judged within the range by which communication quality is secured by the mobile station at the distance and, actually transmission output power to which a certain margin is added is judged. This processing is executed in the prescribed cycle. |
