摘　　要：5G核心网的先进与否与5G技术的应用效果是息息相关的。在新时代,对5G核心网提出了全新的要求。为此,本主要对5G核心网络逻辑层面架构进行了分析,明确其包括两大方面,一是统一核心网络,二是异构接入网络,这两部分都有各自的功能。在此基础上,重点探究了5G核心网演进和主要特点,如接入独立网、分布式网络构架、灵活移动性的演进、基于原生云设计的架构等,以便提升5G核心网性能,促使其逐渐完善,推动其朝着现代化、先进化方向发展,凸显其独特优势,为关注此方面的科技研究者提供参考。Whether 5G core network is advanced or not is closely related to the application effect of 5G technology.In the new era,new requirements have been put forward for 5G core network.For this reason,this paper mainly analyzes the logic level architecture of 5G core network and makes it clear that it includes two aspects:one is unified core network,and the other is heterogeneous access network,both of which have their own functions.On this basis,mainly explores the evolution of 5 g core network and the main characteristics,such as access to independent network,the evolution of the distributed network architecture,flexible mobility,based on the cloud native design architecture and so on,in order to promote 5 g core network performance,prompting them to gradually improve,promote its development toward modernization,the direction of advanced,highlights its unique advantages,provide reference for scientific and technological researchers pay attention to this.
