TR 22.889 (SA1)
Study on Future Railway Mobile Communication System

|   ToC   |   3GPP‑Page   |   Help   |

(W-zip) V15.0.0    2017/03    160 p.

Rapporteur:  Mr. Norp, Toon

The railway community is considering a successor communication system to GSM-R, as the forecasted obsolescence of the 2G-based GSM-R technology is envisaged around 2030, with first FRMCS trial implementations expected to start around 2020.

The Future Railway Mobile Communication System (FRMCS) Functional Working Group (FWG) of the International Union of Railways (UIC) have investigated and summarised their requirements for the next generation railway communication system in the Future Railway Mobile Communication User Requirements Specification (FRMCS URS). The present document is based on this input given by the UIC/ETSI TC-RT NG2R.

The present document analyses FRMCS Use cases, system principles of FRMCS and Interworking between GSM-R and FRMCS in order to derive potential requirements.
