The method includes transmitting a cell activation request, by an upper base station including a base station that has cell coverage including cell coverage of lower base stations, instructing to perform a turn-on operation to lower base stations in an energy saving mode, receiving a Radio Resource Control (RRC) measurement report from a User Equipment (UE), and transmitting a cell deactivation request instructing to perform a turn-off operation for entry into the energy saving mode to at least one turn-off target base station, determined according to the RRC measurement report. The at least one turn-off target base station includes at least one of base stations performing the turn-on operation according to the cell activation request, and the lower base stations includes base stations included in the cell coverage of the upper base station.
