The quality of service high-speed train wireless communication is very important for high-speed railway operation. Modeling and simulation is an effective method to formulate travel plans and improve operational efficiency. In this paper, the SPN is used to establish a wireless communication model of a high-speed train for normal communication states and several system fault recovery states. The parameters are obtained through calculation, and the model is simulated and analyzed using TimeNet. The simulation results show that under the parameters required by the specification, the normal working probability of wireless communication is close to 100%, and the probability of several kinds of failure recovery is more than 95%, which meets the high reliability requirements.
