Two new specifications will allow all vehicles in Europe to make a 112 emergency call with relevant data about an accident or major incident.

The work was completed in the 3GPP Technical Specification Group SA at their SA #43 meeting (9-12 March, 2009), before being presented to ETSI MSG for formal approval by the European standards organization.

The documents specify the eCall in-band modem for the reliable transmission of MSD from an In-Vehicle System (IVS) to the Public Safety Answering Point (PSAP) via the voice channel of cellular and PSTN networks.


  • 3GPP TS 26.267: "eCall Data Transfer; In-band modem solution; General Description"
  • 3GPP TS 26.268: "eCall Data Transfer; In-band modem solution; ANSI-C reference code".

Emilio Davila Gonzalez, the European Commission project officer for ICT for Transport, attended the recent ETSI MSG meeting. He welcomed the completion of the work, stating:

“This will now allow stakeholders to start testing equipment. Vehicle manufacturers, suppliers and the public safety authorities can now start introducing eCall functionality in Europe.”

Work on conformance test definition and performance characterisation is ongoing, with both expected to be complete by TSG SA #44 in June 2009 and TSG SA #45 in September 2009, respectively.
