5G非公共网络技术分析

5G无线通信系统除了满足普通用户移动宽带互联网业务需求,还要向垂直行业、企业渗透,加快国家工业互联网发展和工业智能化进程。为了更好地实现这一目标,非公共网络技术(NPN)开始吸引人们的目光,3GPP已在5G Rel-16标准中加入NPN场景需求、功能的研究和标准化工作。介绍了NPN网络的基本概念,给出5G标准Rel-16版本中NPN的两种组网形态和典型组网方案,以及NPN网络与PLMN网络互操作方法。在此基础上,分析了NPN网络特性和不同的NPN部署方案对网络特性的影响,为运营商和垂直行业企业未来部署NPN网络提供参考。

The Technical Analysis on 5G Non-Public Network

5G wireless communication system should not only meet the mobile broadband Internet service needs of ordinary users,but also penetrate into the vertical industries and enterprises to accelerate the development of national industrial Internet and industrial intelligence.In order to achieve this goal,non-public network(NPN)technology has begun to attract people’s attentions.The NPN scenarios and requirements have been studied and the standardization for NPN functions has been carried out in 3 GPP.In this paper,the concept of NPN is introduced,and two kinds of NPN networks and the solutions of NPN development in 5 G Rel-16 are given,as well as the interworking between NPN and PLMN.Based on this,this paper analyzed the characteristics of NPN networks and the corresponding impact of different deployment solutions of NPN,which can provide the reference for operators or vertical industry enterprises to deploy NPN networks.
