Claim:
1. A method for performing a handover in an electronic device of a wireless communication system, the method comprising: when a handover is required, measuring a power of signals received from a serving base station and nearby base stations, and obtaining load information of the serving base station and the nearby base stations; selecting a first candidate set for a base station capable of performing a handover, using the measured power of the received signals; selecting second candidate set for a base station by comparing a reference load value with load information of a base station in the first candidate set; creating random numbers for each base station in a second candidate set, if two or more base station exist in the second candidate set; comparing the random numbers created for each base station in the second candidate set to thereby select or re-select the second candidate set; re-selecting the second candidate set by changing the reference load value, if a base station does not exist in the second candidate set; and transmitting information on the power of signals received from the selected second candidate set or the re-selected second candidate set and a request message for a handover to the serving base station.
