Claim 8:
9. A handover control method of a first cell in a wireless communication system, the handover control method comprising:
receiving a first measurement report message from a first terminal connected to the first cell;
transmitting a handover preparation request message to each of one or more target cells identified based on the first measurement report message;
receiving a handover preparation acknowledgment message that is a response to the handover preparation request message from at least part of the one or more target cells;
transmitting, to the first terminal, one or more first configuration messages instructing to add each of one or more target cells transmitting the handover preparation acknowledgment message as a candidate primary cell (PCell); and
