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.
