Based on the research of the design theory and method of mobile communication system, this paper proposes a computer-based method and model for the railway mobile communication system aided design. The Egli model is used to design the system index of railway train wireless communication system in plain and hilly region. Methods The algorithm and program for predicting the field strength along the railway in mountainous area with multiple tunnels were developed. The application software for computer aided design such as intermodulation interference testing was also presented. To improve the quality of mobile communication design, accelerate the process of system design is of great significance.
