摘要

近年来中国移动大力建设TD-LTE网络

覆盖广度上已经达到较高水平

但目前有部分场景面临容量不足的问题

并可能出现无法接入、速率偏低等导致用户感知下降的情况。因此

为保持4G竞争领先

需对高业务场景进行多载波扩容。本文首先分析容量瓶颈并探讨扩容改造方法

最后提供典型方案实例供参考。

Abstract

A TD-LTE network has been constructed by CMCC recently. The coverage of their network is high-level. But there are still some area which is lack of capacity. The user experience might be degrade by the phenomenon as access failure or slow netwoke speed caused by it. For holding the lead of 4G network

it is necessary to expand the capacity of network in this condition. This article will analyze the reasons and put forward some methods to expand the capacity. And a example is given to shown how to realize the capacity expansion.
