基于MEC的LTE本地分流技术

Traffic offloading technology in LTE network using MEC

考虑到目前政企、校园以及部分垂直行业低时延以及大流量本地业务传输的需求,给出了一种基于MEC的LTE本地分流技术方案,并针对该方案的可行性进行了深入分析。相比于3GPP中的LIPA/SIPTO技术方案,基于MEC的本地分流方案可以实现MEC平台的透明部署,终端无需支持多个APN连接,从而为用户提供一种"虚拟的LTE局域网"体验。最后,针对该方案在现网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。

Considering the current demand of low-delay and local traffic in some vertical industries, a technical scheme of LTE local shunt based on MEC was proposed, and the feasibility of the scheme was analyzed. Compared with LIPA/SIPTO scheme in 3GPP, MEC-based local streaming scheme could realize the transparent deployment of MEC platform, and the terminal does not need to support multiple APN connections, so as to provide users with a ＂virtual LTE local area network＇experience. Finally, the problems and challenges in the application of the scheme were discussed, which could provide reference for the follow-up research and development.
