Abstract With the rapid development of railway transportation, railway communication is particularly important. In addition to meeting the communication needs of train control, it also guarantees the communication quality of passengers on board. In order to solve the problem of low utilization of spectrum resources in the special railway communication network, a spectrum sharing special railway network communication scheme based on the special railway communication network architecture and cognitive radio technology was put forward this paper. Furthermore, in order to improve the fairness of cognitive base station services, we proposed a secondary user queue management strategy based on Kalman Filter Prediction model to realize dynamic resource allocation. On the premise of satisfying the demand of real-time service for queuing delay, the cognitive base station adjusts the service rate of real-time service according to the predicted changes in the queue length, so as to minimize the queuing delay of NRT service. Finally, the simulation results show that the proposed method can reduce the queuing delay of NRT services, effectively improve the fairness of the cognitive base station services, and ensure the efficient utilization of the limited spectrum resources.
