GSM-R IG evolution

www.gsm-rail.com

The IG is committed to support the deployment of the ERTMS by:

• Extending the deployments of the GSM-R maintaining the compatibility.

• Extending the life cycle of the system

• Support the evolution of the Railway operational communication system to the Next Generation


Current Cab Radio situation

A multitude of scenarios are deployed across the European railways

1. Single/multiple vendor GSM-R cab radios– Various level of standard EIRENE certification– Various level of Country specific features

2. Single vendor Analogue cab radios3. Dual mode Analogue/GSM-R cab radios4. International trains have a multitude of cab radio systems designed to

interface with Country specific requirements.

Chipset/Modules Public Safety LTE status

‐ Major M2M suppliers are already working on the 3GPP roadmap with the greatest chipset suppliers for their native module activity and have many contacts under NDA with major OEM customers involved in « mission critical »

‐ 3GPP feature for mission critical that are considered and need decision:o Band Grouping ?

B14 / fallback on B2-4-12-13 B28-68 / fallback on B3-7-20

o 3GPP features ? HPUE QCI, MC-PTT, Pro-Se… LTE cat Cat 9, 12 or no specific req?

o Form factor ? miniPCIe LGA Carrier board withLGA to miniPCIe

Voice Cab Radio upgrade paths» The challenge

• GSM-R & Next Generation Cab radio will need to co-exhist on the same train Cab during the transition phase

• The excellent interoperability performance of current GSM-R radios will need to be maintained

• Upgrade not replacement to reduce cost

• Re-use of existing installations to reduce cost

• Enable the introduction of additional applications & functionalities

• Cyber security strategy for the IP based transmissions.

» The Lower cost approach solution• Use standard and commercially available radio modules instead of

creating specific railway variants.

• An easy swap of IP radio modules will future proof and allow to follow 3GPP releases

• Use of frequencies that are available on the public band

• Integrate the new IP functionality on a separate processor board

Voice Cab Radio upgrade paths


» The Lower cost approach solution• Integrate the new IP functionality with existing interface boards (PA/

DSD/ Driver key/ Alarms/ JRU/ etc.

• Integrate the existing Driver Control Panel with the new functionality for a multi-mode configuration.

• Insert optional additional functionalities: GPS/ Data services for train condition monitoring/ Wi-Fi, LTE etc.

• Enable optional applications: Driver Advisory System/ Track condition monitoring/ video surveillance etc.

» The higher cost approach solution

• Use Railway specific radio modules. • Use a dedicated frequency band • Create a separate IP radio• The new IP radio will have interface boards (PA/ DSD/ Driver key/

Alarms/ JRU/ etc.• Replace the existing Driver Control Panel to enable the dual mode

operation.• Enable optional additional functionalities: GPS/ Data services for train

condition monitoring/ Wi-Fi etc.• Enable optional applications: Driver Advisory System/ Track condition

monitoring/ video surveillance etc.

EDOR upgrade paths


The introduction of additional features like GPS; 4G modules; Wi-Fi and processor cards will enable most on-board units to run additional application targeted to offer unique services to the Train/network operating companies.

• Driver Advisory system ( to improve timetable accuracy and energy savings)

• Remote Condition Monitoring (enable each train to monitor the track condition)

• Train Condition Monitoring (enable remote management of the train asset)

• Service Wi-Fi (for the use of train personnel)• Video surveillance• Multi bearer QoS management in line with Subset 0.93

Handhelds evolution

16

Mobile GSM-R modem coupled to mobile devices via a low-power Bluetooth 4.1

• GSM-R-specific functions of the EIRENE device classes GPH, OPH and OPS

• Battery• Bluetooth interface • Status indicators• GSM-R band

1717

Use as GPH

Setup• Regular smartphone + modem

Functions• GPH replacement

• Data modem max. 9.6kbit or GPRS

Advantages• Can be used with already existing telephones

• No new user interface

• Only one telephone required

• Easy acceptance by end user

User interface based on telephony app• Functional registration

• SMS

• Voice calls

• Emergency call

Conclusions

• The frequency band decision will greatly impact the cost of the migration.

• The use of GSM-R frequencies for the new IP radio will make the filtering upgrades (currently part of Eirene 8.16) obsolete.

• Railways that have not completed a GSM-R rollout and still operate analogue systems will require an ad-hoc strategy.

• Railways that have implemented a multivendor on-board approach will also require an ad-hoc strategy.
