In respect of 112-eCall (operating requirements defined in EN 16072), this document defines specifications for the provision of eCall via satellite communications networks (Satellite-IMS-112-eCall and Satellite-TPS-eCall). As with the existing provisions for eCall for Classes M1/N1 vehicles, these are specified within the paradigm of OEM fit equipment at the point of manufacture. This document includes only the requirements for the provision of Satellite IMS-112-eCall using satellite telecommunications and Satellite-TPS-eCall. NOTE 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 (TPSP) before the call is forwarded to the PSAP).
