Abstract

Abstract:

5G is a mobile communication network that meets the development needs of future communication.Due to the use of higher frequencies,more base BS are needed,results in huge CAPEX and OPEX.RAN sharing will be an effective way to speed up the 5G commercial process and reduce costs and increase efficiency.The possibility of 5G RAN sharing by analyzing the scheme under SA/SA and SA/NSA architecture was explored,then a systematic theoretical basis for 5G RAN sharing and co-construction was given.

Key words: 5G, SA, NSA, RAN sharing

对比项	SA/SA	SA/NSA
语音	EPS回落/ EPS 回落	EPS 回落/VoLTE
基站互操作	交界区异厂商时N2口切换	和运营商既有流程一致
异厂商	交界区边缘支持异厂商	共享区设备需和其中一方设备同厂商
网络规划和优化	共享区边缘结合双方需求进行	共享区需要同时考虑SA/NSA，复杂
网管	统一架构网管	共享区网管需支持两种架构，复杂
终端	共享、非共享区要求一致	共享、非共享区要求一致
其他		（1）基站支持双架构连接，基站成本高；
		（2）当主建方为 NSA 组网时，与主建方需求冲突：主建方 NSA 组网的诉求在于NSA成熟度高，且建网初期投资较低，而共建共享方案建网初期成本较高，且设备成熟度低
