    • 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.
    • 提供了一种在无线通信系统中的硬切换方法。 硬切换方法包括在与服务BS进行通信时检查从至少一个相邻基站(BS)中的每一个接收的信号的信噪比(SNR),以及如果接收到的信号的SNR被消除则消除干扰 从所述至少一个相邻BS中的每一个满足选择条件; 如果所述干扰消除信号的SNR与所述干扰信号的SNR之间的差达到切换请求阈值,则向所述服务BS发送切换请求; 并且在从服务BS接收到切换批准时,向服务BS发布通信信道,并且将呼叫连接到提供SNR达到阈值的干扰信号的BS。
