摘要:

首先结合国内运营商的 5G 商用情况分析了非独立(non-standalone,NSA)组网的劣势,建议控制NSA投入,以独立(standalone,SA)组网为目标开展5G网络建设;然后基于5G核心网标准进展及R16标准的主要变化,分析5G SA核心网商用部署及后续2G/4G/5G融合演进规划部署建议,包含5G边缘计算节点的商用部署建议以及后续的规划建设建议。建议以终为始、尽早统筹开展2G/4G/5G融合组网规划建设,以有效保护投资、降低组网和维护复杂度,实现控制面全云化部署、用户面分布式下沉部署的目标架构;为5G SA核心网建设提供参考借鉴。

关键词: 5G核心网, SA, 融合组网, 演进

Abstract:

Firstly,the disadvantages of NSA networking based on the 5G commercial situation of domestic operators were analyzed,it was suggested to control NSA investment and carry out 5G network construction with SA as the goal.Then based on combing the progress of 5G core network standard and the main changes of R16 standard,the commercial deployment of 5G SA core network based on regional network cloud and the following 2G/4G/5G convergence evolution planning and deployment proposal was analyzed,it included the commercial deployment suggestions of 5G edge computing nodes and the subsequent planning and construction suggestions.It was suggested that the planning and construction of 2G/4G/5G integrated networking should be carried out as soon as possible,in order to effectively protect investment,reduce the complexity of networking and maintenance,realize the target architecture of full cloud deployment of control plane and distributed sinking deployment of user plane.It provides reference for the construction of 5G SA core network.

Key words: 5G core network, SA, integrated networking, evolution
