[Problem] To provide: a handover control method capable of identifying a target cell in a hand-in phase, even in a network configuration having relay devices connected in multiple stages; a relay device; and a target cell selection method. [Solution] A wireless communications system having a base station control device (14) and a first relay device (1) connected to a communications network, at least one first base station (12) connected under the control of the base station control device, at least a second relay device (2) connected under the control of the first relay device, and at least one second base station (4-6) connected under the control of the second relay device, and wherein: the first relay device obtains cell information for a cell controlled by a second base station under the control of the second relay device; and, the first relay device identifies a target cell for handover by using the cell information, in a hand-in phase in which a wireless station (16) hands over from a wirelessly connected first base station (12) to a second base station (6). |
