Abstract: Embodiments of the present invention provide a cell handover method, a base station and a system, which relate to the field of wireless communications technologies. The method includes: determining, by a source eNB according to uplink RSRP of a UE in a serving cell and a target cell, whether to hand over the UE from the serving cell to the target cell; and if yes, acquiring UE parameters including TA of the UE in the target cell, and sending UE data and the UE parameters to a target eNB, where the TA is used for uplink synchronization between the target eNB and the UE.

Abstract translation: 本发明的实施例提供了一种与无线通信技术领域有关的小区切换方法，基站和系统。 该方法包括：根据源eNB根据服务小区和目标小区中的UE的上行RSRP确定是否将UE从服务小区切换到目标小区; 并且如果是，则在目标小区中获取包括UE的TA的UE参数，并且向目标eNB发送UE数据和UE参数，其中TA用于目标eNB和UE之间的上行链路同步。
