摘要:

由于能够以低成本提供5G无线网络中多样化的业务场景,网络切片和边缘计算一直以来深受学术界和工业界的提倡。网络切片通过将网络实体划分成多个逻辑独立网络,为不同业务场景提供所需服务,而边缘计算利用网络中用户和边缘网络设备的计算和存储功能,承载部分核心节点中的控制、管理、业务功能,能够提升传统移动宽带业务能力和应对新兴的机器类业务。将网络切片和边缘计算融合,提出了基于边缘计算的接入网络切片,能够满足5G中广泛的用例和商业模型,使得运营商能够根据第三方需求和网络状况以低成本为用户灵活提供个性化的网络服务。

Abstract:

As a cost-efficient way to meet the wide range of use cases that the fifth generation wireless network will provide,network slicing and edge computing have been advocated by both academia and industry.In the concept of network slicing,the network entities are sliced into several logical networks to provide the requested services for different use cases.The edge computing pushes the frontier of computing applications,data,and services away from centralized nodes to the logical extremes of a network and even the user equipments,which can improve the traditional mobile broadband service capability,and handle with the emerging machine type service.The edge computing based radio access network slicing was proposed as a combination of edge computing and network slicing.The radio access network slicing can meet the diverse use cases and business models in 5G,and enable operators to flexibly provide personalized network services based on third-party need and network situation in a cost-efficient way.

Key words: 5G, edge computing, network slicing
