摘　　要：介绍了3GPP R16标准中提出的非公共网络技术(Non-Public Network,NPN)的两种组网方式和应用现状,分析了企业对5G专网的需求以及公专融合的趋势。结合NPN与公共陆地移动网(Public Land Mobile Network,PLMN)部署的关系,提出了两种典型的5G公网和专网融合部署模式:连续模式、重叠模式。并针对两种模式下需要重点解决的业务连续性和并发连接问题,介绍了3GPP R17标准中提出的两种技术方案。This paper introduces the non-public network technology put forward in 3GPP R16 and two networking methods as well as application status.It analyzes the enterprises′demand for 5G private network and the trend of integration of NPN and public land mobile(a public land mobile network,PLMN).Based on the relationship between NPN and PLMN,two typical 5G public-private integrated deployment modes are proposed:continuous mode and overlapping mode.In order to solve two typical problems in these two modes:service continuity and connection connection,two technical solutions of R17 are discussed.
