5G端到端网络切片进展与挑战分析

Analysis on the Advances and Challenges of 5G End-to-End Network Slice

随着5G端到端网络切片商用部署的逐步推进,在切片实施过程中遇到一些问题和挑战,因此亟需对其当前的研究进展及挑战进一步分析。从对5G端到端网络切片的系统性论述切入,首先介绍了5G网络切片的架构和功能,之后梳理了目前国内外标准组织对网络切片及其增强技术的研究进展,最后识别并深入分析了端到端网络切片面临的挑战,包括SLA保障能力、与MEC和终端的协同能力、以及跨域的管理编排能力等。为后续进一步推动5G端到端网络切片的商用规模化部署,助力网络切片赋能5G行业应用提供参考。

With the gradual progress of commercial deployment of 5G end-to-end network slice,there are some problems and challenges in the implementation of network slice.Therefore,it is urgent to further analyze the current research progress and challenges of slicing.Starting from the systematic discussion on 5G end-to-end network slice,this paper first introuces the architecture and function of 5G network slicing,and then combes the research progress of network slice and its enhancement technologies in domestic and foreign standard groups.Finally,the challenges faced by end-to-end network slice are identified and analyzed in depth,including SLA guarantee capabilities,coordination capabilities with MEC and terminals,and cross-domain management and orchestration capabilities.This paper provides a reference for further promoting the commercial scale deployment of 5G end-to-end network slices and assisting network slice in empowering 5G industry applications.
