The measured total power supply and the number of terminals (traffic volume) covered by a base station are obtained from the base station. From the traffic volume, the total power supply required to the base station is estimated. The measured total power supply is compared with the estimated total power supply, and a correction value to the maximum downlink power supply per channel is calculated when it is determined that the base station has remaining power for radio wave transmission. The correction value of the maximum downlink power supply per channel is set at the base station. Because the corrected value is larger than the pre-correction maximum downlink power supply per channel, the base station can transmit radio waves at a larger power making speech quality of its terminals improve when the base station has remaining power supply.
