Abstract: A base station includes a receiving unit, a determining unit, a control unit, and a transmitting unit. The receiving unit receives a connection request signal when the base station is in a power-saving state. The determining unit, when the receiving unit receives the connection request signal, determines whether a priority of the base station is higher than a priority of a different base station that belongs to a same group as the base station. The control unit, when the determining unit determines that the priority of the base station is higher than the priority of the different base station, causes the base station to return from the power-saving state to a normal state. The transmitting unit wirelessly transmits a notification signal after the base station is returned to the normal state by the control unit.
