摘要
R15版本的5G核心网,引入了服务化架构,在推动了通信网络云化进程的同时,也让网元数目增多,网间HTTP信令链路负担大大增加。依据3GPP R16版本,研究服务化架构增强技术,分析网络架构上引入SCP网元在不同模式下给网络带来的利弊,分析网络功能集概念的引入为提高网络可靠性带来的优势,最后对服务化架构进一步的增强演进方向进行展望。
The 5G core network of the R15 introduced SBA technology,which promotes the process of communication network cloud,and also greatly increases the number of network elements and the burden of HTTP signaling link of the network.Based on 3GPP R16,this paper will study the enhancement technology of eSBA,analyze the advantages and disadvantages brought by the introduction of SCP network element in network architecture under different modes,analyze the advantages brought by the introduction of NF set concept to improve network reliability,and finally forecast the evolution direction of further enhancement of SBA.
