部署LTE对3G网络规划的挑战

Challenges to 3G Network Planning after Deploying LTE

随着物联网和移动宽带时代的到来,移动数据业务呈现爆炸式增长,现有的移动网承载技术将很难满足未来数据业务需求,移动业务市场需求和竞争是LTE技术产生与发展的源动力。本文分析了LTE演进的必然性及目前的发展情况;并从频段使用、承载网、核心网等方面讨论了在引入LTE时,网络规划应重点处理好的问题。

With the advent of the Internet of Things and the wideband of mobile communication,the mobile data service is showing an explosive increase.The existing mobile network bearing technology can hardly meet future demand of data service.The market need and competition of mobile service is the technical generation and development source power of LTE technology.This article analyses the inevitability of LTE evolution and the current development,and discusses the key problems of network planning that should be dealt with when we introduce LTE from band use,bearing network,core network and so on.
