| description | Cognitive radio technology was used to build cognitive radio networks in long-term evolution railway communication systems,and cognitive base station network architecture and MRR scheduling algorithms were proposed to improve the spectrum utilization of railway dedicated networks.In particular,the FIFO policy for cognitive LTE-R base stations in a single vehicle gateway causes excessive delay in real-time services of secondary users,and a cognitive LTE-R base station queue management strategy based on priority of service types was proposed.This strategy gave priority to sending packets with large service type values to the queue,so as to achieve the purpose of prioritizing real-time services.Simulation results show that under the premise of ensuring the normal communication of vehicles,the constructed cognitive base station can provide passengers with additional internet access links,and at the same time,improve the spectrum utilization rate of the LTE-R communication system.In addition,the cognitive base station queue management strategy based on service type value priority can effectively reduce the delay of passenger real-time services. |
