CEN/TS 17249-3:2018

In respect of 112-eCall (operating requirements defined in EN 16072), this document defines additional specifications for the provision of eCall for coaches and buses.
As with the existing provisions for eCall for Category M1/N1 vehicles, these are specified within the paradigm of being OEM fit equipment supplied with new vehicles.
NOTE 1  The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of other work, and in respect of the operational requirements for any such aftermarket solutions for coaches and buses, will use the specifications of this document as a reference point.
NOTE 2  The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third party service provision by comparison, involves the support of an intermediary third party service provider before the call is forwarded to the PSAP.) The specifications herein relate only to the provision of 112-eCall or IMS-112-eCall, and do not provide specifications for third party service provision of eCall, although in the case of 112-eCall or IMS-112-eCall for coaches, links to third party provision of service aspects (such as passenger lists) may be required.
