3GPP drives GSM-R to a new track

August 5, 2016

By Juergen Merkel, Nokia, rapporteur of the FS_FRMCS study item.

At the recent 3GPP SA plenary, a study item was approved - to investigate the requirements for a new railway communication system, as a successor to the GSM-R service.

GSM-R is facing a number of challenges:

  • The system life-cycle is coming to an end, with vendor support uncertain beyond 2030
  • Extra capacity is required in some areas to support railway operations
  • The rollout of European Rail Traffic Management System (ERTMS) has increased the strain on the GSM-R network

To have a successor technology in place by 2020 for trials and by 2022 for deployment, the International Railway Union (UIC) have published a user requirement specification in their paper “Future Railway Mobile Communication System - FRMCS” (see S1-161250).

When complete, SA1 will have identified the normative 3GPP work needed to make the FRMCS a success.

About GSM-R

GSM-R is an adaptation of GSM technology to suit the railways’ needs for communication. 3GPP GSM-R provides the services necessary to support Voice Group Call, Voice Broadcast Call and prioritization of these services by “(enhanced) Multi-Level Precedence and Pre-emption service ((e)MLPP).

GSM-R has been elaborated in cooperation of the International Railway Union (UIC) and ETSI TC SMG - the predecessor of 3GPP - in the second half of the 90’s.
