Abstract
Provided is a hard handover method in a wireless communication system. The hard handover method includes checking a signal-to-noise ratio (SNR) of a signal received from each of at least one neighboring base station (BS) while in communication with a serving BS, and canceling interference if the SNR of the signal received from each of the at least one neighboring BSs satisfies a select condition; sending a handover request to the serving BS, if a difference between a SNR of the interference-canceled signal and a SNR of the interference signal reaches a handover request threshold; and upon receipt of a handover approval from the serving BS, releasing a communication channel to the serving BS, and connecting a call to a BS that provides an interference signal whose SNR has reached the threshold.
