(Main)Intelligent transport systems - eSafety - Part 2 : eCall for HGVs and other commercial vehicles
General Information
- Abstract
The Scope of this document is limited to the provision of eCall from a commercial vehicle prime mover /rigid body truck designed for conveying cargo (UNECE Category N).
Within the context of 112-eCall (operating requirements defined in EN 16072), this document defines specifications for the provision of 112-eCall for regulated commercial vehicles, including rigid body trucks and variants thereof, prime mover and trailer combinations (sometimes called "semi’s", road trains [one prime mover with multiple trailers]) and other regulated commercial vehicles (for example vans carrying medical supplies or radioactive material).
As with the existing provisions for 112-eCall for Category M1/N1 vehicles, these are specified within the paradigm of being OEM fit equipment supplied with new vehicles.
The work of CEN/TS 16405 is adopted and extended in this document. (A revised edition of CEN/TS 16405(:2018) will remain the principal reference document for the content and definition of the commercial vehicle optional additional data set.)
This document specifies the requirements for the use of 112-eCall by a commercial vehicle prime mover /rigid body truck and determines circumstances where it is appropriate to additionally provide new optional additional data as determined in CEN/TS 16405(:2018 or later) as Schema C for use in a packet switched environment which is not constrained by the 140 byte limit.
Unless superseded by European Regulation on some future date, all data schemas specified in CEN/TS 16405 are "Optional Additional Data" (OAD) concepts, as enabled in accordance with EN 15722 as part of the minimum set of data. As OAD they, and the elements within them, are, by definition, "optional" with use at the discretion of the operator of the vehicle.
NOTE 1 The provision of eCall from IVS located within trailers is not included in this document.
NOTE 2 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 commercial vehicles, will use this document as a principle reference point.
NOTE 3 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 for commercial vehicles, links to third party provision of service aspects (such as cargo contents) may be required.

Overview
CEN/TS 17249-2:2018 - "Intelligent transport systems - eSafety - Part 2: eCall for HGVs and other commercial vehicles" specifies how 112‑eCall is to be implemented for regulated commercial vehicles (UNECE Category N). The Technical Specification focuses on OEM‑fitted in‑vehicle systems (IVS) for prime movers and rigid body trucks, including prime‑mover + trailer combinations (semi’s, road trains) and other regulated commercial vehicles (e.g., vans carrying special cargo). Trailer‑installed IVS and aftermarket retrofits are explicitly out of scope (the latter will be covered by separate work).
This standard adapts and extends existing eCall rules (EN 16072 and EN 15722) and adopts CEN/TS 16405 optional additional data concepts, adding provisions for packet‑switched transmission (Schema C) when the 140‑byte MSD limit is not applicable.
Key topics and technical requirements
- Scope and vehicle categories: Targets commercial vehicles (N1, N2, N3) designed primarily for goods transport; defines regulated commercial vehicles and exclusions.
- 112‑eCall paradigm: Emphasises direct vehicle call to the most appropriate PSAP (Public Safety Answering Point) - covers 112‑eCall and IMS‑112‑eCall; does not specify third‑party service models (although integration points for cargo data may be needed).
- MSD and Optional Additional Data (OAD): Uses EN 15722 minimum set of data (MSD). OAD concepts from CEN/TS 16405 (Schemas A, B and AdditionalData2) are adopted; Schema C is introduced for richer data over packet‑switched networks without the 140‑byte constraint.
- Triggering and data requirements: Defines when eCall is generated (automatic/manual) and the associated data elements to be provided to PSAPs. Includes cargo data handling and distribution of MSD.
- Conformance and testing: References end‑to‑end conformance testing standards for circuit‑switched and IMS/packet networks.
- Implementation paradigm: Assumes OEM fit (supplied with new vehicles) and clarifies optional nature of additional data per EN 15722.
Applications and users
Who will use this standard:
- OEMs and vehicle integrators implementing eCall in new HGVs and commercial fleets
- Telematics and IVS suppliers developing eCall modules for heavy vehicles
- Emergency services / PSAPs coordinating response workflows for commercial vehicle incidents
- Regulators and type‑approval bodies assessing compliance and harmonisation across EU member states
- Fleet operators evaluating benefits of enhanced MSD/OAD for incident response (cargo type, hazardous goods)
Practical uses include enabling automatic emergency notification with location and vehicle context, improving PSAP situational awareness for HGV incidents, and supporting richer data exchange over packet networks (Schema C).

Introduction
As a result of European Regulation, from 2018, all new model Category M1/N1 vehicles will be
equipped with 112-eCall. Other model Category M1/N1 vehicles may be voluntarily equipped with 112-
eCall.
The current eCall Regulation covers only M1 and N1 Category vehicles (cars and vans). The European
Commission’s “ICT Rolling Plan (2017) states the objective “Action 1 Develop technical
specification/standards for the implementation of eCall in vehicles of categories other than M1 and N1 and
for other user types, taking into account requirements included within type approval regulation as well as
ongoing activities in this area (pilots, CEF,…).” And it goes on to explain “.for the extension to other
vehicles types and services, such as Heavy Duty Vehicles, Power Two Wheelers or Hazardous Goods
tracking, and other classes of vulnerable road users”.
See CEN/TR 17249-1 for context.
The EC CEF project I_HeERO has also addressed the issues relating to eCall for HGVs, coaches and
busses and vehicle centric solutions for powered two wheel vehicles (P2WV) and have passed these
results to CEN/TC 278 PT1507 who are charged to provide specifications for the provision of eCall for
Heavy Goods Vehicles, coaches and busses, agricultural tractors, and powered two-wheel vehicles.
Unlike other additional Categories of vehicles, considerable and substantive work has already been
undertaken both in Standards Deliverables and practical testing of those deliverables in respect of HGVs
and other commercial vehicles, leading to the publication of CEN/TS 16405:2017. This document takes
this work further, and will cause CEN/TS 16405 to be revised.
Consistent with CEN/TS 16405, CEN PT 1507 have interpreted the loosely used term HGV´s to include
all commercial vehicles, including rigid body trucks and variants thereof, prime mover and trailer
combinations (sometimes called “semi’s”) road trains (one prime mover with multiple trailers) and
others. The term includes any regulated commercial vehicles. 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.
The work of CEN PT1507 has provided CEN/TC 278/WG 15 with identification of data to be specified in
a revision of CEN/TS 16405 for an additional Schema C, which may be additionally sent in an eCall that
is not limited to 140 bytes. A revision of CEN/TS 16405 will provide the ASN.1 data definitions for
Schema C, and will revise the data elements in the next edition of CEN/TS 16405.
1 Scope
The Scope of this document is limited to the provision of eCall from a commercial vehicle prime mover
/rigid body truck designed for conveying cargo (UNECE Category N).
Within the context of 112-eCall (operating requirements defined in EN 16072), this document defines
specifications for the provision of 112-eCall for regulated commercial vehicles, including rigid body
trucks and variants thereof, prime mover and trailer combinations (sometimes called “semi’s”, road
trains [one prime mover with multiple trailers]) and other regulated commercial vehicles (for example
vans carrying medical supplies or radioactive material).
As with the existing provisions for 112-eCall for Category M1/N1 vehicles, these are specified within the
paradigm of being OEM fit equipment supplied with new vehicles.
The work of CEN/TS 16405 is adopted and extended in this document. (A revised edition of
CEN/TS 16405(:2018) will remain the principal reference document for the content and definition of
the commercial vehicle optional additional data set.)
This document specifies the requirements for the use of 112-eCall by a commercial vehicle prime mover
/rigid body truck and determines circumstances where it is appropriate to additionally provide new
optional additional data as determined in CEN/TS 16405(:2018 or later) as Schema C for use in a packet
switched environment which is not constrained by the 140 byte limit.
Unless superseded by European Regulation on some future date, all data schemas specified in
CEN/TS 16405 are “Optional Additional Data” (OAD) concepts, as enabled in accordance with
EN 15722 as part of the minimum set of data. As OAD they, and the elements within them, are, by
definition, “optional” with use at the discretion of the operator of the vehicle.
NOTE 1 The provision of eCall from IVS located within trailers is not included in this document.
NOTE 2 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 commercial
vehicles, will use this document as a principle reference point.
NOTE 3 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 for commercial vehicles, links to third party provision of service aspects (such as cargo contents) may be
required.
