5G网络切片技术增强研究

网络切片作为5G网络的关键技术之一,不仅服务于个人用户,还需要满足各行各业的数字化转型需求,因此需要提供差异化的能力满足不同的体验要求。从网络切片的技术演进角度分析网络切片在3GPP标准中的最新进展,包括R15版本定义的网络切片的整体架构及基础业务流程、R16版本网络切片特定鉴权授权关键流程、R17版本正在研究的网络切片属性定义等关键问题,并简要分析端到端网络切片当前面临的问题。

Research on Technology Enhancement of 5G Network Slice

As one of the key technologies of 5 G network,network slicing serves individual users,and also meets the requirements of digital transformation for various industries.Therefore,it is necessary to provide diversified capability to meet different experience requirements.This paper analyzes the latest development of network slicing in 3 GPP standard from the perspective of technology evolution,including the overall architecture and fundamental process of network slicing defi ned by R15,key fl ow of specifi c authentication and authorization of network slice in R16,and network slicing attributes defi nition under R17 study,and then the current problems of end-to-end network slicing are also briefl y discussed.
