摘要： 介紹了3GPP R16標(biāo)準(zhǔn)中提出的非公共網(wǎng)絡(luò)技術(shù)(Non -Public Network,，NPN)的兩種組網(wǎng)方式和應(yīng)用現(xiàn)狀,，分析了企業(yè)對5G專網(wǎng)的需求以及公專融合的趨勢。結(jié)合NPN與公共陸地移動(dòng)網(wǎng)(Public Land Mobile Network,，PLMN)部署的關(guān)系,，提出了兩種典型的5G公網(wǎng)和專網(wǎng)融合部署模式：連續(xù)模式、重疊模式,。并針對兩種模式下需要重點(diǎn)解決的業(yè)務(wù)連續(xù)性和并發(fā)連接問題,，介紹了3GPP R17標(biāo)準(zhǔn)中提出的兩種技術(shù)方案。

Abstract： 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.
Key words : non-public network(NPN)；stand-alone NPN(SNPN),；service continuity,；simultaneous connection
