【摘? 要】5G無線通信系統(tǒng)除了滿足普通用戶移動(dòng)寬帶互聯(lián)網(wǎng)業(yè)務(wù)需求,還要向垂直行業(yè)、企業(yè)滲透,加快國家工業(yè)互聯(lián)網(wǎng)發(fā)展和工業(yè)智能化進(jìn)程。為了更好地實(shí)現(xiàn)這一目標(biāo),非公共網(wǎng)絡(luò)技術(shù)(NPN)開始吸引人們的目光,3GPP已在5G Rel-16標(biāo)準(zhǔn)中加入NPN場景需求、功能的研究和標(biāo)準(zhǔn)化工作。介紹了NPN網(wǎng)絡(luò)的基本概念,給出5G標(biāo)準(zhǔn)Rel-16版本中NPN的兩種組網(wǎng)形態(tài)和典型組網(wǎng)方案,以及NPN網(wǎng)絡(luò)與PLMN網(wǎng)絡(luò)互操作方法。在此基礎(chǔ)上,分析了NPN網(wǎng)絡(luò)特性和不同的NPN部署方案對網(wǎng)絡(luò)特性的影響,為運(yùn)營商和垂直行業(yè)企業(yè)未來部署NPN網(wǎng)絡(luò)提供參考。

[Abstract]?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 3GPP. In this paper, the concept of NPN is introduced, and two kinds of NPN networks and the solutions of NPN development in 5G 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.

0? ?引言
5G通信技術(shù)的發(fā)展不僅是為廣大移動(dòng)互聯(lián)網(wǎng)用戶提供更高速和優(yōu)質(zhì)的服務(wù),更是成為推動(dòng)工業(yè)互聯(lián)網(wǎng)發(fā)展的使能技術(shù),而工業(yè)互聯(lián)網(wǎng)也是加快5G商用規(guī)模部署,實(shí)現(xiàn)5G商用價(jià)值的重要突破口之一。
回顧過去,信息科技(IT)與操作技術(shù)(OT)很少有交集,但進(jìn)入工業(yè)互聯(lián)網(wǎng)時(shí)代,透過物聯(lián)網(wǎng)、大數(shù)據(jù)與云端智能,使IT與OT兩者最終展開對話,由OT領(lǐng)域的傳感器獲取數(shù)據(jù),上傳IT領(lǐng)域的云端中心執(zhí)行大數(shù)據(jù)分析,繁衍出各種創(chuàng)新應(yīng)用。第五代(5G)網(wǎng)絡(luò)可以在這種集成中發(fā)揮關(guān)鍵的支持作用,能夠以無處不在的方式連接各種設(shè)備[1]。5G發(fā)展不僅使移動(dòng)運(yùn)營商受益,也將使制造業(yè)、物流等各行業(yè)從產(chǎn)業(yè)升級中受益[2]?!?br>
