The main purpose of this project is to validate the FRMCS V2 Specifications & V3 target requirements with precommercial FRMCS system components in realistic operational conditions and to feed-back the result to the railway eco-system in order to timely start the migration to FRMCS across the European railway system. 

Objective 1: Provide a future proof FRMCS architecture with the necessary telecommunication elements

• 5G SA (Stand Alone) architecture (core and access);
• IMS/SIP-core and MCX;
• TOBA (Telecom On-Board Architecture) equipment;
• Track Side Gateway;
• Cab radio equipment (: Voice Application Subsystem (VAS));
• Dispatcher;
• Monitoring equipment (system and radio);
• ETCS / ATO / TCMS simulators compatible with FRMCS interfaces, including (ETCS) PKI and KMS (national and international), based on H-2-N.

Objective 2: Test the necessary functions of the FRMCS V2 set of specifications

• Voice functions for both drivers and controllers;
• Railway Emergency Communication – REC (Combined REC alert and REC voice);
• Data functions (including ETCS, ATO and TCMS applicative simulations);
• Combination of voice and data applications;
• Location and positioning service (e.g., Railway Emergency Communication, driver to controller communications based on driver’s location) and internal FRMCS System usage (e.g., FRMCS domain change);
• Time service (e.g. timestamp for location reporting of REC);
• Usage of various frequencies: RMR bands (900 and 1900 MHz) and some MNO band(s);
• FRMCS multipath concepts using data paths of MNO and FRMCS/RMR;
• FRMCS inter-domain transition and cross-border testing;
• FRMCS domains interconnection (e.g., communications between users served by different FRMCS Service Domains);
• GSM-R / FRMCS interworking and transition;
• Interoperability between FRMCS components from various manufacturers;
• Quality of Service with performance measurements at system and radio levels;
• Cybersecurity (elements of).

Objective 3: Validation and return on experience

• Provide material elements to confirm / correct / amend / evolve the FRMCS V2 set of specifications;
• Communicate these elements to the UIC FRMCS Programme for the closing of FRMCS V3 set of specifications ahead of update of CCS TSI,
