Specialist Task Force 390:
Improved Mobile Receiver Performance: improved mobile receiver characteristics and test procedures for GSM-R nearly interference free operation

Who we are:

Team Leader: Mr. Dirk Schattschneider Deutsche Bahn AG
Team Members: Mr. François Deroche RFF
Mr. Kalle Tuominen OMNITELE LTD, behalf of Finnish Railways
Mr. Horst Fenske TRIORAIL GmbH & Co.KG
Mr. Laurent Poutas UIC
Mr. Walter Karnthaler Funkwerk Systems Austria GmbH.
Mr. Hendrik Holz Hoermann Funkwerk Kölleda GmbH.
Dr. Massinissa Lalam SAGEM Communications SAS

What we do:

The STF 390 is dealing with the improvement of the GSM-R mobile receivers and the corresponding test procedures to guarantee a nearly interference free operation.

Since GSM-R is relevant to railway-safety specific regulations apply. This includes the obligation under the directive 96/48/EC on the interoperability of the trans-European high speed railway network and directive 2001/16/EC on the interoperability of the conventional trans-European Railway network and the related technical requirements specifications. Therefore, GSM-R is expected to be in operation even beyond the year 2020-2025 timeframe.

Increasingly putting into operation GSM base stations in 900 MHz frequency band beside the ER-GSM band causes interferences which are reported to affect operation of GSM-R terminals in several European countries. Since several month there are also interferences caused by placing UMTS in the frequency range above the existing GSM-R frequencies in some countries.

For more details, see our Terms of Reference

Why we do it:

The purpose of the work is to achieve a better co-existence between the GSM-R and public mobile services by providing standards for better mobile receiver performance like amended blocking capabilities and IM3 interference response rejection.

How we do it:

The STF 390 will provide by the end of October 2010 an ETSI Technical Specification on the improved mobile receiver parameters (blocking capability, IM3, ACS, etc.) needed by GSM-R for nearly-interference-free usage in Europe.

Deliverables:

  • DTS/RT-EGSM-R-002 “Railway Telecommunications GSM-R improved receiver parameters” (NWI) To be published as version1.1.1.

Time plan:

The STF will produce the deliverables according to the following time scale:

  • TB adoption of WI 2009/07/08
  • Early Draft 2010/05/15
  • Stable Draft 2010/06/22
  • Draft for approval 2010/09/17
  • WG approval (delete if no WG) 2010/10/12
  • TB approval (RT#39) 2010/10/14

This specification will be based on existing 3GPP specifications and identifies improved receiver characteristics and applicable test cases.

The work of the STF390 will also encompass a concept of internal or external filters, installation requirements in railway trains for both receive and transmit sections.

The results of the work are also intended to be given to the 3GPP standardization process to ensure compliance with the 3GPP specifications on GSM-R
