NSA组网与共建共享背景下的移动性管理方案

Mobility Management Solution in the Context of NSA Networking and Co-construction and Sharing

NSA组网下,由于NSA终端的信令面承载在LTE上,终端的移动性管理复杂度高,需采用适用于现网的LTE与NR协同策略,以保障更好的NR业务体验。从NSA组网与共建共享背景出发,对NSA终端与4G终端的移动性需求进行了分析,提出了适用于非共享场景与共享场景的移动性管理方案,最后针对共享场景产生的终端管理问题进行案例分析。

Since signaling plane of the NSA terminal is carried on LTE under NSA network,the mobility management of the terminal becomes complicated,which needs to consider more on the LTE and NR coordination strategy applicable to the existing network for better NR service experience.Based on the background of NSA networking and co-construction and sharing scenarios,it first analyzes the mobility requirements of NSA terminals and 4G terminals,and then proposes mobility management schemes suitable for non-shared scenarios and shared scenarios,finally it analyzes a terminal management problem generated by sharing scenarios.
