摘要

移动边缘计算（mobile edge computing

MEC）技术通过为无线接入网提供IT 和云计算能力，使得业务本地化、近距离部署成为可能，从而促使无线网络具备低时延、高带宽的传输能力，并且回传带宽需求的降低极大程度减少了运营成本。同时，MEC通过感知无线网络上下文信息（位置、网络负荷、无线资源利用率等）并向业务应用开放，可有效提升用户的业务体验，并且为创新型业务的研发部署提供平台。首先介绍MEC技术，细化并给出MEC平台框图。此外，针对基于MEC平台的本地分流功能，给出了详细的技术方案，并与3GPP本地分流方案LIPA/SIPTO进行对比分析。更进一步，针对MEC技术在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。

Abstract

Mobile edge computing（MEC）makes it possible to deploy and provide service locally

which is close to the users

by enabling the IT and cloud computation capacity at the radio access network (RAN).Thus

MEC can improve the quality of experience (QoE) by reducing the latency

and decrease the network operation cost through reducing backhaul capacity requirement.Meanwhile

based on the network context information (location

network traffic load

radio information

etc) exposure to applications and services

MEC can further improve the QoE of user and provide the platform to third-party partners for application and service innovation.Besides the introduction of MEC

the detailed MEC platform was presented.Furthermore

the traffic offloading solution based on MEC was proposed and compared with the solution of local IP access and selected IP traffic offload (LIPA/SIPTO).In addition

the problems and challenges of the MEC were also discussed in detail.
