城域网典型架构及LTE承载演进探讨

On the LTE loading evolution and typical framework of the metropolitan network

本文简要介绍城域传送网和LTE核心层的典型架构,同时分析了LTE承载需求及城域网的承载瓶颈。针对网络存在的问题,给出多种城域网演进思路并进行分析比较,以便针对不同的网络情况选择相匹配的演进方案。

The essay introduces the typical framework of metropolitan transmission network and LTE core layer. Meanwhile, it analyzes LTE loading demand and loading bottleneck. Aiming at the problems being on the net, it gives the ways to the kinds of metropolitan network evolution and conducts the comparison, so that we can choose the matching evolution programme in the different network situation.
