MOBILE COMMUNICATION SYSTEM, METHOD OF CONTROLLING POWER, AND BASE STATION APPARATUS OF SMALL CELL

摘要

A mobile communication system of an overlay configuration includes a plurality of small cells that are arranged in a macro cell, wherein a base station of each of the plurality of small cells includes a transition unit configured to shift to a standby state in which transmission power is turned off when a mobile terminal is not contained in a corresponding one of the plurality of small cells, and a report unit configured to measure a quality of radio waves received from the mobile terminal that is present in the macro cell, and report a measurement result to a base station control device, wherein the base station control device includes a selection unit configured to select one of the plurality of small cells in which the mobile terminal is to be contained, based on the measurement results reported from the base stations of the plurality of small cells, and an instruction unit configured to instruct the base station of the selected one of the plurality of small cells to shift to a communication state in which the transmission power is turned on.
