cdma2000网络的高铁覆盖优化研究

Research on Optimization of cdma2000 Network for High-speed Rail

高铁列车运行速度快,导致列车内手机通话质量较差。本文对高铁覆盖优化的特点进行了较为详细的分析,并以京津高铁的cdma2000网络优化为例,介绍了利用既有网络资源对高铁进行覆盖优化的思路和方法,提出了适用于高铁沿线基站规划和优化的一般性原则。

The high speed leads to the poor quality of communication with mobile phones in high- speed trains. This paper analyses the feature of net- work optimization for high-speed rail. With the ex- ample of cdma2000 network optimization for Bei- jing-Tianjin rail, it shows the idea and method of using existing network resources to optimize the network coverage, and offering the general princi- ples suitable for planning and optimizing base stations along high-speed rail way.
