Introduction
This document complements EN 15722:2015, Intelligent transport systems — ESafety — ECall minimum
set of data and provides an “Optional Additional Data” concept to be transmitted as part of the MSD
transmission in accordance with EN 15722:2015.
In the event that a vehicle triggers a 112 eCall, the MSD is sent to a “public safety answering point” (PSAP).
The PSAP operator decodes the MSD data (usually, but not necessarily, automatically placed on the
operator's screen). The operator is put in wireless communication (via a mobile phone connection) with
the occupants of the vehicle.
However, sometimes, the operator does not receive any response from the vehicle. This may be due to
one of three reasons:
a) The equipment has failed/has a fault;
b) The occupants are dead, unconscious or otherwise unable to speak;
c) The occupants have left the vehicle and moved to a place of safety (for example behind a crash
barrier or well away from the road [this would often be the advice given by a PSAP in any event]).
NOTE 1 The communications media and means of transferring the eCall MSD are not defined in this document.
See the list of referenced Standards.
As, by this stage, the Minimum Set of Data (MSD) has already been successfully sent; it is usually relatively
easy to detect an in-vehicle system problem (the line has gone totally silent, indicating a dropped call, or
there is some interference noise etc.).
If the line appears to be operational, the responding PSAP has a dilemma. He/she has no way to determine
whether the cause is (b), where it is essential to quickly get emergency response to the scene, or (c), in
which case it may not even be necessary to send an emergency response to the scene.
Based on experience with pre-eCall emergency call systems using cellular telephone links, experience is
that more than 90 % of the time, the reason is (c), but without further information, the PSAP cannot take
that risk and is to send emergency response to the site.
However, current generation vehicles generally now provide the possibility for a 'Bluetooth' link between
the mobile phone of the occupants and the car. Thus, when the registered phone user enters, or is in close
proximity, to the vehicle (usually, but not always, activated when the ignition is turned on) his/her mobile
phone connects via Bluetooth to the vehicle's audio system No information about the user itself, or
her/his phone number is exchanged, as this information is neither known to the mobile phone nor is it
part of any Bluetooth exchange mechanism. That said, the vehicle does know, at any time, which
registered user phones are in or near the vehicle and linked to it at the time of the incident.
If, by means of prior consent, the user who registers his/her phone with the vehicle system enters his/her
phone number, it is possible to provide the PSAP with that phone number as an “Optional Additional
Data” (OAD) concept as part of the MSD.
In the event of a 'silent' call, the PSAP is therefore able to telephone the mobile phone number that was
linked to the vehicle at the time of the incident. It is expected that this will significantly reduce the number
of ‘silent’ calls.
This addition does not enable the vehicle to be tracked or logged in any way other than any other linked
mobile telephone, and, of course, in 112 eCall, the eCall phone connection to the network does not occur
at all until after the event (triggering of eCall).
NOTE 2 This specification provides an optional additional concept as part of the MSD sent to the PSAP, it does
not involve making any direct connection with the telephone number provided, but simply makes that number
available to the PSAP to call if available and required.
This document defines the OAD concept, requirements to ensure the user's consent to the provision of
the linked phone number, any provisions to be made regarding privacy and advice to PSAPs on the use of
the extra information.
1 Scope
This document defines an eCall “Optional Additional Data" concept for the “Minimum Set of Data” (MSD)
to be transferred from a vehicle to a 'Public Safety Answering Point' (PSAP) in the event of a crash or
emergency via an 'eCall' communication transaction.
This document defines:
a) Protocol requirements to ensure phone user consent to the provision of the linked 'phone number
to the PSAP in the event of an eCall triggering incident;
b) Definition of the OAD concept “Linked mobile Telephone Number” (LTN);
c) Privacy provisions;
d) Advice to PSAPs on the use of the eCall OAD LTN;
e) Example of an in-vehicle sequence generating the LTN OAD and forwarding it as part of the MSD.
For clarity, the communications media protocols and methods for the transmission of the eCall message
are not specified in this document.

3.2
eCall
emergency call generated either automatically via activation of in-vehicle sensors or manually by the
vehicle occupants; when activated it provides notification and relevant location information to the most
appropriate 'Public Safety Answering Point’, by means of mobile wireless communications networks,
carries a defined standardized ‘Minimum Set of Data’ notifying that there has been an incident that
requires response from the emergency services, and establishes an audio channel between the occupants
of the vehicle and the most appropriate 'Public Safety Answering Point'
3.3
minimum set of data
direct, timely data content of an eCall message to the PSAP operator receiving the emergency call
containing information about the location of the incident, providing detail characterising the vehicle, and
potentially sometimes also providing additional data that is deemed relevant

public safety answering point
‘first level’ responder to whom an emergency call/eCall is directed
