Intelligent transport systems - eSafety - eCall via satellite
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.)
Intelligente Verkehrssysteme - eSicherheit - eCall über Satellit
In Bezug auf den 112 eCall (Betriebsbedingungen in EN 16072 festgelegt) legt dieses Dokument Spezifikationen zur Bereitstellung von eCall über Satellitentelekommunikationsnetzwerke fest (Satelliten IMS 112 eCall und Satelliten TPS eCall).
Wie bei den bereits bestehenden Bestimmungen zu eCall für Fahrzeuge der Klasse M1/N1 werden diese innerhalb des Paradigmas für Ausrüstung spezifiziert, die vom Originalgerätehersteller zum Zeitpunkt der Herstellung eingebaut wird.
Dieses Dokument umfasst nur die Anforderungen für die Bereitstellung von Satelliten IMS 112 eCall unter Verwendung von Satellitentelekommunikation und Satellite TPS eCall.
ANMERKUNG Das 112 eCall-Paradigma beinhaltet einen Direktanruf vom Fahrzeug bei der zuständigen Notrufzentrale (en: Public Safety Answering Point, PSAP). (Zum Vergleich: Die Diensterbringung durch Dritte beinhaltet die Unterstützung eines zwischengeschalteten externen Dienstleisters (en.: third party service provider, TPSP), bevor der Anruf an die Notrufzentrale weitergeleitet wird).

CEN/TS 17312:2019 (E)
Introduction
In accordance with a European Regulation, from March 2018, all new model Class M1/N1 vehicles will be
equipped with 112-eCall. Other model class M1/N1 vehicles may be voluntarily equipped with 112-eCall
and eCall support for other classes of vehicles will be enabled in the near future.
In its study CEN/TR 17249-1, the report observed that where a satellite telecommunications service
provider supports IMS, this means that 112-eCall over IMS can be supported, in accordance with
CEN/TS 17184, via the satellite telephone network, because IMS is an IP based service which is radio
agnostic. Generally, this means IMS eCall can be supported by any IP network and so will enable eCall via
satellite in IMS supporting satellite networks. (However, there is no fall-back to circuit switched eCall.)
Satellite communications that support internet protocol, but do not support IMS, may be able to provide
the service using an agreed CeIMS.
Satellite networks are geared for handling emergency calls – in terms of prioritization and handling. In
the maritime sector, the use of satellite networks is mandated and regulated for ships above a certain
size. Similar emergency call services have existed for decades on satellite networks for personal safety.
Most current satellite telephone systems support access to the internet through the use of IP protocol,
and therefore support IP-addressing. These systems are technically able to support IMS-112-eCall. This
of course requires a satellite communications transceiver in the vehicle, but modern satellite
communications systems can now usually be accessed by a standard-sized sharks-fin or flat panel
antenna.
As with other existing eCall provision, this specification is based on OEM fit equipment. The provision of
eCall for aftermarket vehicles will be the subject of other work.
It should also be noted that there will be no fall-back provision to circuit switched eCall in the event that
there is no local PSAP equipped to handle IMS (as provided for in 3GPP release 14), but this is not
required (see below).
As the ‘cell’ for a satellite system covers the entire continent, an eCall via satellite cannot identify the
“most appropriate” PSAP from the location of a cell tower, and so an alternative system is bound to be
specified.
Modern satellite telecommunications systems have the advantage that most (but not all) systems provide
the GNSS location of the source as part of the call establishment (in order to align signals between source
and satellite) and can therefore identify the location of the vehicle to a 1st level reception point PSAP. The
GNSS location information is not usually available outside of the network, except for certain types of
services, but can be made so for safety services.
This means that, in countries where the Administration is prepared to provide the satellite
telecommunications service provider with a single central level 1 PSAP IP address for satellite eCalls, eCalls
can be provided and supported in remote locations where there is limited or no 2G/3G/LTE/4G coverage
available. As, in this paradigm, the call is always made over IMS to an IMS capable level 1 PSAP address,
there is no requirement for fall-back to circuit switched eCall.
The central 1st level PSAP can then identify the GNSS location of the source of the eCall and redirect the
IMS VOIP call to the “most appropriate PSAP” on the basis of the GNSS location information provided in
the call establishment, or, where the GNSS location is not available in the call establishment, can read the
MSD to find the location of the vehicle and similarly redirect the IMS VOIP call to the “most appropriate
PSAP”. As the communication session is packet switched, call forwarding to the most appropriate PSAP
is a simple exercise and the MSD will be provided in the call setup (and therefore available in any call
forwarding).
Where the Administration is not prepared to offer a central 1st level PSAP address to the satellite
telecommunications service provider, satellite eCall can be provided via a TPSP.

CEN/TS 17312:2019 (E)
Note, however, that eCalls over satellite (and certainly TPSP calls via satellite) are unlikely to be provided
free of carrier network charges and require satellite communication transceiver equipment in the vehicle.
Satellite-IMS-112-eCall is likely to be of particular interest to Administrations where there are users for
categories of vehicle that have to cross areas of intermittent cellular coverage and across multiple
countries and road networks. This may also be of interest for agricultural and forestry vehicles in
locations where low population density (such as rural areas, Northern Scandinavia and mountainous
regions) does not justify the provision of land based cellular telephone networks.
NOTE Support for Satellite-IMS-112-eCall is probably not needed in countries where there is good mobile
network coverage across the length and breadth of the land.
For vehicles known to spend significant time in areas that do not have the benefit from good
GSM/UMTS/LTE/4G coverage, Satellite-IMS-112-eCall can provide the benefit of eCall to vehicle users.
This document provides specifications for the provision of eCall via satellite telecommunications.

6 General overview of 112-European eCall and satellite eCall
6.1 Circuit switched 112-eCall
Satellite-IMS-112-eCall, by definition of this specification, is always made via an IMS supporting satellite
telecommunication link to an IMS supporting level 1 PSAP. No circuit switched eCall is supported within
this specification.
6.2 Packet switched 112-eCall using IMS
6.2.1 General
The eCall communication and session for Satellite-IMS-112-eCall shall always be made in accordance with
CEN/TS 17184 (Conformance tests provided in CEN/TS 17240), with the exception that there is no fall-
back to circuit switched eCall.
6.2.2 Areas without cellular wireless telecommunication coverage
This specification is directed at the provision of 112-eCall in areas which are not served (at the time that
the call is made) by GSM, UMTS, E-UTRAN, LTE or other terrestrial cellular telecommunications networks
that may be deployed in the future.
Within this specification, there is a general assumption that a vehicle will first try to make a terrestrial
112-eCall, and that if this fails because there is no connectivity to the cellular network, will attempt a
satellite-IMS-112-eCall by using satellite telecommunications. However, this is not a requirement, and the
equipment installer may elect to use satellite-IMS-112-eCall as its first choice. (For example, in mobile
forestry equipment designed to work in remote forests). As with all eCall specifications to date, the means
of triggering and method of triggering, (and therefore the election and decision making process to initiate
a satellite-eCall) is at the determination of the OEM installing the equipment.
6.2.3 Evolution of satellite telecommunication networks
Over recent years the evolution of satellite telecommunication technology and networks has led to lower
cost user equipment, and easier alignment to the sate
