摘　　要：随着5G网络的商用和大规模部署,5G设备单站成本高、站址需求大、功耗高等问题成为运营商5G网络建设和运营中的巨大挑战。在国家网络强国战略和提速降费的要求下,运营商需要探索新的网络建设和运营模式,在保障5G网络高质量建设的基础上提升5G网络的效益和资产运行效率,网络共建共享模式成为电信运营商5G运营新模式。从网络共享技术方案分析入手,分析了异网漫游和接入网络共享技术方案,结合中国联通和中国电信5G网络共享,分析了接入网共享下NSA网络共享方案和SA演进方案。With 5G network large-scale commercial deployment,the high cost of 5G equipment,the large number of site requirement and the high power consumption of 5G equipment become huge challenges for 5G network construction and operation to operators.To carry out the national Cyberpower strategy,operators need to explore a new mode of network construction and operation.The co-construction and sharing of 5G network becomes a new pattern for operators.It starts with the analysis of the network sharing technology scheme,analyzes the roaming and RAN sharing technology scheme,and analyzes the NSA network sharing scheme and SA evolution scheme based on the 5G network sharing of China unicom and China telecom.
