Wireless base station, mobile station, wireless communication system, control method for wireless base station, and recording medium

A mobile station comprising:

• a battery;
• a communication unit configured to communicate with a wireless base station;
• a measuring unit configured to measure radio quality of a signal transmitted in each of a plurality of cells;
• and
• a control unit configured to transmit, to the wireless base station via the communication unit, information indicating a measurement result of the radio quality of the signal transmitted in each of the plurality of cells, obtained by the measuring unit, and a state of the battery of the mobile station, and,
• upon being notified a signal, the radio quality of which is to be measured, from the wireless base station via the communication unit, causes the measuring unit to measure the radio quality of the notified signal.

A control method for a wireless base station, the method comprising:

• communicating with a mobile station which measures radio quality of a signal transmitted in each of a plurality of cells;
• acquiring load information related to a load of a network including a wireless base station forming the cell;
• receiving information indicating a measurement result of the radio quality of the signal transmitted in each of the plurality of cells and a state of a battery of the mobile station, from the mobile station;
• determining a signal, radio quality of which is to be measured by the mobile station, based on the measurement results of the radio qualities and the state of the battery of the mobile station, indicated in the received information, and the load information acquired by the acquisition unit;
• and
• notifying the signal determined to be measured to the mobile station.
