摘要

网络切片作为软件定义网络（software defined networking

SDN）技术框架体系的核心内容，已经成为5G网络演进过程中一项关键技术特性。同时，5G网络演进中的无线接入网络对泛在接入需求的进一步提升，使无线资源管理也必定要围绕着资源虚拟化和设计切片化为重点展开技术演进。从无线网络切片技术的需求和功能场景定义出发，讨论分析了网络切片技术在无线资源管理中的研究现状，进而给出其在无线接入网络设计中所面临的挑战，为后续研究和系统演进提供指导。

Abstract

As a core content in SDN(software defined networking) technical framework

network slice has become a key technology in 5G network evolving processing.In the meanwhile

radio resource management should be focused on virtulized resource and sliced design in the RAN(radio access network)

which is being confronted with much more ubiquitous access in 5G evolution.Based on the technical demand and function scenario definition for network slicing in RAN management

the states of the art in radio resource management were discussed

and moreover

the challenges in RAN design were also proposed

which would perform references for the future research.
