FRMCS – Mission Critical Communication in 5G
Course Contents
This course examines FRMCS, the Future Railway Mobile Communication System: the railway profile of the 3GPP Mission Critical services, and the designated successor to GSM-R.
FRMCS is specified in three strata — a transport stratum carried by the 3GPP 5G system, a service stratum built on the 3GPP Mission Critical framework, and the railway applications above them, defined by the UIC railway profile. The course is organised the same way and works upward through the three.
It starts with what railway operational communication demands of a network and where the specifications come from, then builds the system from the bottom: the 5G transport, the Mission Critical services that run on it, and the railway applications the UIC profile defines above them. It closes with GSM-R interworking, which is what lets a railway migrate section by section.
Target Audience
This course is intended for technical professionals involved in the specification, procurement, design, deployment or operation of railway communication systems — infrastructure managers, railway undertakings, system integrators and equipment suppliers — and for those preparing for FRMCS in an organisation that runs GSM-R today.
Course outline
Prerequisites
Participants are expected to have a technical background. The course builds the 5G access and core network features FRMCS relies on from the ground up, so prior 5G knowledge is helpful but not assumed; the APIS course “5G Standalone Architecture and Features” gives a fuller grounding. Familiarity with GSM-R is useful but not required.
