1. A method, performed by a terminal, for a handover in a wireless communication system, the method comprising:
receiving, from a source base station, first control information for a last handoverfrom a base station, wherein the first control information includes a handover margin indicating a time required for the source base station to handover the terminal to a target base station;
determining whether to perform the last handover, based on the first control information and radio signal information acquired via measurement of a radio signal;
in case that the terminal determines to perform the last handover, transmitting, to the source base station, a handover request message; and
determining whether a handover command message is received from the source base station.
