论文摘要
预计GSM-R将在2030年之前渗透，并且需要合适的继任者。由国际铁路联盟（UIC）定义，未来的铁路移动通信系统（FRMC）包含许多未来的用例。这些用例不仅应确保在网络覆盖范围内，而且还确保揭示的场景确保定期沟通。 FRMC中仍缺乏关于外部网络通信的标准，因此本文着重于网络沟通，并打算为标准化提供参考和指导。我们首先对FRMC中的网络外用例进行了全面的摘要和分析。然后，我们概述现有技术（GSM-R，TETRA，DMR，LTE-V2X和NR-V2X），可能支持网络沟通。此外，我们模拟和评估现有技术的性能。仿真结果表明，可以通过基于LTE-V2X或NR-V2X的增强功能满足FRMC中的网络沟通要求。最后，我们为未来的研究指示提供了为行业和学术界提供见解。
GSM-R is predicted to be obsoleted by 2030, and a suitable successor is needed. Defined by the International Union of Railways (UIC), the Future Railway Mobile Communication System (FRMCS) contains many future use cases with strict requirements. These use cases should ensure regular communication not only in network coverage but also uncovered scenarios. There is still a lack of standards on off-network communication in FRMCS, so this article focuses on off-network communication and intends to provide reference and direction for standardization. We first provide a comprehensive summary and analysis of off-network use cases in FRMCS. Then we give an overview of existing technologies (GSM-R, TETRA, DMR, LTE-V2X, and NR-V2X) that may support off-network communication. In addition, we simulate and evaluate the performance of existing technologies. Simulation results show that it is possible to satisfy the off-network communication requirements in FRMCS with enhancements based on LTE-V2X or NR-V2X. Finally, we give some future research directions to provide insights for industry and academia.
