Abstract: A UE does not immediately perform handover after receiving a handover command from a serving base station, but instead backups that message and continuously compares the signal strength of a serving base station and the signal strength of a target base station and performs a handover to the target base station at the best timing when handover is required. Once the timing of handover is determined, the UE transmits a handover indication message to the serving base station, and thereafter the UE performs a handover to the target base station.

Abstract translation: 在从服务基站接收到切换命令之后，UE不立即执行切换，而是备份该消息，并且连续地比较服务基站的信号强度和目标基站的信号强度并执行到目标的切换 基站需要切换时的最佳时间。 一旦确定了切换的定时，则UE向服务基站发送切换指示消息，此后，UE对目标基站进行切换。
