摘　　要：提出了几种主频点接入的选择策略,以及不同RRC信令开销的频点切换管理方法。通过理论分析结合系统级动态仿真,对提出的策略和方法进行了比较。从不同的载波聚合场景、用户移动速度、频点测量周期等方面研究分析了切换次数、切换失败率、RRC重配置数量等性能。It introduces several selection policies of primary component carrier access, and mobility management methods for different request of RRC signaling overhand. It contrasts the performance from different aspects such as CA scenarios, mobility speed, measurement period, and shows the comparison result of total handover number, handover failure rate, RRC reconfiguration.
