Research on technologies and application scenarios of 5G non-public network

Abstract： In this paper, emergence background and intention of NPN are introduced, with the characteristic of two kind of NPN networks and their key technologic content. The relation between NPN and PLMN and technical requirement of NPN network entities are analysed. On the view of network deployment, comparison among Slicing, SNPN and PNI-NPN are presented, then selection of technology for private network is suggested.
