5G MEC融合架构及部署策略

摘要

移动/多接入边缘计算(MEC)技术通过将计算存储能力与业务服务能力向网络边缘迁移,使应用、服务和内容可以实现本地化、近距离、分布式部署,从而在一定程度上解决了5G增强移动宽带、低时延高可靠以及大规模机器通信类终端连接等场景的业务需求.同时MEC通过充分挖掘移动网络数据和信息,实现移动网络上下文信息的感知和分析并开放给第三方业务应用,有效提升了移动网络的智能化水平,促进网络和业务的深度融合.因此,首先根据5G典型业务场景分析MEC的价值与意义.其次基于ETSI和3GPP的研究进展,提出了面向5G的MEC融合架构,并讨论分析了MEC的总体部署策略.更进一步,针对MEC技术在未来5G网络应用中可能存在的问题与挑战进行了讨论,为后续研究发展提供参考.%Mobile/multi-access edge computing (MEC) technology migrates computing storage capabilities and service service capabilities to the edge of the network,enabling applications,services and content to be localized,close-range and distributed.Therefore,to a certain extent,the business requirements of 5G enhanced mobile broadband,low latency and high reliability and large-scale machine communication terminal connection are solved.At the same time,the MEC fully exploits mobile network data and information to implement the awareness and analysis of context information of the mobile network and open it to third-party service applications.This effectively enhances the level of intelligence in mobile networks and promotes the deep integration of networks and services.Therefore,the value and significance of the MEC was firstly analyzed according to the typical 5G service scenario.Secondly,based on the research progress of ETSI and 3GPP,a MEC fusion architecture oriented to 5G was proposed,and the overall deployment strategy of MEC was discussed and analyzed.Furthermore,the possible problems and challenges in the future application of MEC technology in 5G networks were discussed to provide reference for subsequent research and development.
