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.
