Abstract: The 5G network requires large construction investment and high operation cost, there is a large pressure on 5G industrial income. In order to lower down the cost of network construction and operation, and implement the new idea of “innovation, coordination, green, open, sharing”, more and more operators focus on 5G network sharing which can realize fast service capabilities by efficient network coverage. In this paper, the technology of 5G network sharing will be analyzed thoroughly including basic principle, user experience, impact on the network and potential risk in order to provide some useful reference to operators.
Key words : 5G network sharing,;inter-networks roaming;radio access network sharing

隨著5G標準的成熟與完善,,2019年成為5G商用的元年,,全球進入了5G的部署與商用階段,隨之而來的就是5G的大規(guī)模建網需求以及高額的建網成本,。從5G網絡建設投資方面來看,,5G單站價格高、站址密集,、傳輸需求大,,故5G網絡的CAPEX成本巨增;從5G網絡運營維護方面來看,,目前單個5G有源天線(Active Antenna Unit,,AAU)最大功耗約為現(xiàn)網RRU的3~4倍,能耗巨大,,此外,,5G AAU與現(xiàn)網2/3/4G無源天線需相互獨立部署,天面空間更加緊張,,且相應增加鐵塔租金支出,,故若達到相同的覆蓋規(guī)模,5G網絡的TCO相較于4G網絡將有數(shù)倍提升,。從當前移動通信網絡營收方面來看,,單位流量價格進一步降低,,且5G業(yè)務模式尚不清晰,行業(yè)應用收入后延,,整體來看,,5G產業(yè)收入壓力巨大。因此,,網絡共享作為在保證網絡覆蓋的同時降低運營商網絡投資的方案備受運營商關注,。
