5G NSA和SA组网边界优化方案的研究及应用

5G网络未完全演进成SA only模式之前，在NSA&SA和SA only组网边界区域，仅支持NSA的终端会给网络带来干扰，严重影响用户感知。而且存量NSA终端用户换机需要一定周期，该类问题预计将持续较长时间。为了保证用户感知，本文在传统规避方案的基础上，提出了在双模站点与SA only站点边界区域设置隔离带的新方案，在宏站-室分及宏站-宏站两种场景验证效果良好。

Research and application of 5G NSA /SA network boundary optimization scheme

Before the 5G network has fully evolved into SA only mode, in the boundary area of NSA&SA and SA Only networks, terminals that only support NSA will bring interference to the network and seriously affect user perception. Moreover, it takes a certain period for NSA stock users to change their machines , so such problems are expected to last for a long time. In order to ensure user perception, this paper proposes a new scheme of setting the isolation belt in the boundary area between the dual-mode and SA only base station on the basis of the traditional avoidance scheme. The scheme is proved to be effective in both scenarios of macro- room station and macro-macro station.
