关于5G组网技术路线的分析与建议

2019年6月，工业和信息化部正式发布5G商用牌照，加快了我国5G网络部署进程。3GPP制定的5G 国际标准包含了非独立组网（non-standalone，NSA）和独立组网（standalone，SA）两种模式，鉴于两者的差异，介绍了NSA和SA的基本概念，从部署需求与性能、工作难点与重点等方面对两种组网模式的主要特点进行了对比，分析了从NSA到SA网络演进的两条路线和需要关注的两个问题，并针对我国5G产业的快速成长，特别是运营企业实施发展策略、选择合适的组网架构给出了建议。

Analysis and suggestion on 5G networking technology route

In June 2019, the Ministry of Industry and Information Technology officially issued a 5G commercial license, which accelerated the deployment of China’s 5G network. The 5G international standards developed by the 3GPP include non-standalone (NSA) and standalone (SA) modes. In view of the differences between the two, the basic concepts of NSA and SA were introduced. The main characteristics of the two networking modes were compared with performance, work difficulties and key points. The two routes from NSA to SA network evolution and two issues that need attention were analyzed, and the rapid growth of China’s 5G industry was pointed out. In particular, the operating companies had implemented recommendations for implementing development strategies and selecting appropriate networking architectures.
