Abstract
With the rapid development of high-speed railway, the high-speed railway network has gradually increased its requirements for communication quality. There are still some shortcomings in the current network at present, such as inflexible resource scheduling, poor reliability, and inconvenient operation and maintenance. The system requires high reliability and real-time CBTC (communication-based train control system) services; the demand for throughput of the necessary video services is very high. Therefore, it is necessary to design a radio resource scheduling strategy that is specifically proposed for the system in order to more efficiently use radio resources to improve system performance. According to the predicted railway communication situation, a multiservice bearer model based on a private network is used. In this mode, the RAD [1] algorithm cannot meet all the requirements of system performance. This paper proposes an improved RAD resource scheduling algorithm based on service cache. Simulation results show that compared with RAD algorithm, our new improved algorithm achieves better packet call throughput and delay.
