Future Rail line Flexible Correspondence Structure considering 5G and MNOs for Fundamental Rail Line Hailing Organizations

In order to demonstrate the viability of implementing 4G/5G systems based on mobile network operators (MNOs) to transmit signaling-critical data for railway systems as part of a potential solution for the Future Railway Mobile Communication System, this paper describes the prototype and tests conducted (FRMCS). The protocol-stack approach is used to develop this communication system, introducing KPIs for the physical layer, network layer, and application layer (RSRP, RSRQ, and SINR) (signalling communication timeout). In order to examine the data traffic behaviour in a communications lab, the analysis focuses on characterising signaling critical railway data. The study also confirms the method in a real-world railroad setting.
