摘要: CTCS-3级列控系统通过GSM-R无线通信进行车地数据传输,保障列车安全高效运行。由于GSM-R网络业务承载能力有限,为适应高速铁路未来发展和兼容现有列控系统,需要研究兼容业务承载能力更强的5G-R网络和既有GSM-R网路的系统解决方案。提出一种兼容GSM-R与5G-R互联互通的列控系统无线通信解决方案,介绍双网融合的分层结构、传输结构和数据传输方案,并说明双网切换的典型应用场景。

关键词: 列控系统, GSM-R, 5G-R

Abstract: CTCS-3 train control system transmits train-trackside data through GSM-R wireless communication to ensure safe and efficient operation of trains. Due to the limited service carrying capacity of GSM-R network, in order to adapt to the future development of high-speed railway and be compatible with the existing train control system, it is necessary to study system solutions compatible with 5G-R network with stronger service carrying capacity and the existing GSM-R network. In this paper, a train control system wireless communication solution based on compatible with 5G-R and GSM-R interoperability is proposed, and the layered structure, transmission structure and data transmission scheme of dual-network integration are introduced, and a typical application scenario of dual-network handover is illustrated.

Key words: train control system, GSM for Railways, 5G for Railways
