Claim Text:
1. A base station comprising: a first determination unit that determines whether a terminal in connection with the base station is a terminal passing a cell of the base station; a calculation unit that calculates handover frequency having a predetermined value of the terminal determined as the passing terminal by the first determination unit; and a control unit that controls transmission power in accordance with the frequency calculated by the calculation unit, wherein the control unit controls coverage based on presence of a history of connection of the passing terminal to the base station in past predetermined time and based on time of current connection of the passing terminal to the base station to suppress avoidable handover caused by the terminal which temporarily passes the cell, wherein when the frequency calculated by the calculation unit is a second predetermined value or more, the control unit decreases the transmission power, and when the frequency calculated by the calculation unit is less than the second predetermined value, the control unit increases the transmission power.
