The European Union eCall requirements, recommendations and guidelines were developed by eSafety Forum, with important additional work produced by ETSI MSG, GSME, 3GPP, and CEN.

Previous work in TR 22.967 'Transfer of Emergency Call Data', examined the issues associated with the transmission of emergency call data from a vehicle to a PSAP. This analysis identified that the preferred option be based on an in-band modem solution.

The objective of this work was to examine and describe the in band modem solution (in band modem and any necessary interface to the ME) for eCall. Because eCall is a European regional requirement, it shall not have an impact on the global circulation of terminals. In the interest of not duplicating work, the set of in-band solutions that were considered are those preferred by GSME unless significant improvements are available. The work assessed the suitability of existing 3GPP in-band solutions, e.g. CTM, to satisfy the requirements for eCall.

This TR assesses the suitability of CTM for eCall.
