There is provided a handover control method that does not produce quality deterioration or other similar problems during handover in a mobile communication system in which a first channel shared by a plurality of mobile stations and second channels exclusively used by respective mobile are used in combination. A handover control method according to the present invention comprises: a step in which a data signal is transmitted from one base station 30A to a mobile station 10 by using a first channel; a step in which a control signal is transmitted from a plurality of base stations 30A, 30B including the base station 30A to the mobile station 10 by using a second channel; a step in which the mobile station 10 receives a plurality of control signals; a step in which, of the plurality of control signals received, information regarding reception quality of the control signal from the base station 30A that transmitted the data signal is transmitted from the mobile station 10 to the base station 30A; and a step in which information relating to reception quality is received by the base station 30A and transmission control is performed of the data signal transmitted by the base station 30A, in accordance with the received information relating to reception quality.
