摘要
网络切片功能是未来5G蜂窝移动网络的必选功能,如何在5G蜂窝移动网络无线接入侧实现端到端(E2E)的网络切片功能是业界的研究重点。针对该问题,介绍了第三代合作伙伴计划(3GPP)中的相关标准进展,并系统阐述了其背后的技术发展脉络、缘由,以及各自优劣点。认为5G网络已初步具备E2E的网络切片能力,但仍有一些技术需要进一步发展和提升。
The network slicing function is the required function of the future 5G cellular mobile network.How to realize and implement the end to end(E2E)network slicing function in 5G celullar next generation-radio access network(NG-RAN)is one of the hot topics.Based on various facts of 3rd Generation Partnership Project(3GPP)standardization process,the comprehensive views about its development are given and advantages and disadvantages of its related essential technical issues are analyzed.It is considered that the 5G network has the capability of E2E network slicing,but there are still some technologies that need to be further developed and promoted.
