eCall – Saving lives across Europe
What is eCall?
eCall defines a manually or automatically initiated emergency call (E112) from a
vehicle to an emergency agency, supplemented by sending a minimum set of
emergency related data MSD
� It is foreseen that eCall will be offered on all new vehicles in the EU by April 2018
� It’s using Europe’s single emergency number 112
� Establishes a voice connection to an emergency services
� The MSD is transported in-band the voice call
� Within the MSD the vehicle's location is transmitted to the emergency services
� eCall is based on GSM network infrastructure (UMTS is optional)
A feature to improve traffic safety and save lives

ERA-GLONASS –
Saving lives in the Russian Federation
What is ERA-GLONASS?ERA-GLONASS refers to an interoperable in-vehicle emergency call service
introduced to be operated across the Russian Federation.
� It is foreseen that ERA-GLONASS will be offered on all new vehicles in the RU by January 2015
� ERA-GLONASS is using the general emergency number 112 when an accident happens
� The ERA-GLONASS System is analogous to the European eCall system
� Is harmonized with it for the purpose of process compatibility in regard to main functional properties
� use of in-band modem as the main data transmission
� unified content and format of mandatory data transmitted in the MSD
� uniform procedures for initiation and termination of duplex voice communication
� ERA-GLONASS is based on GSM and UMTS network infrastructure
� ERA-GLONASS provides fall back solution based on SMS
� ERA-GLONASS provides potential for Value Added Services as Stolen Vehicle Tracking or
Road tolling

eCall/ERA-GLONASS - Definitions
ı eCall: A manually or automatically initiated emergency call (E112) from
a vehicle, supplemented with a minimum set of emergency related data
(minimum set of data (MSD))
ı MSD: The minimum set of data, sent from the vehicle to a public
safety answering point (PSAP), includes important information about
the accident, for example, vehicle identity, location information and
time-stamp.
ı PSAP: A public safety answering point is a call center responsible
for answering calls to an emergency telephone number for police,
firefighting and ambulance services.

Block Name Description
1 Format version MSD format version: set to 1 for the current format EN15722:2011
2 Message identifier Session specific counter; starts at 1 and is incremented with every
retransmission
3 Control Conveys the following information:
• Automatic or manual activation
• Test call (TRUE/FALSE)
• Position can be trusted (TRUE/FALSE)
• Vehicle class
4 Vehicle ID VIN (vehicle identification number) according to ISO3779
5 Propulsion type (energy storage) Gasoline, diesel, hydrogen, electric, etc. (TRUE/FALSE)
6 Time stamp Timestamp of incident event
7 Vehicle location Latitude and longitude (ISO 6709) in milliarc-seconds
8 Vehicle direction Deviation from the direction to the magnetic north pole in 2 degrees steps
9 Recent vehicle location n-1 Change in latitude and longitude compared to the last MSD transmission
10 Recent vehicle location n-2 Change in latitude and longitude compared to the last but one MSD
transmission
11 No. of passengers Minimum known number of fastened seatbelts; omitted if no information is
available
12 Optional additional data Optional information for the emergency rescue service (103 bytes, ASN.1
encoded); may also point to an address, where this information is located
Data content of the transmitted MSDThe standard EN 15722 describes the structure of the eCall MSD, below table summarizes its content.
MSD = Minimum Set of Data, ASN.1 = Abstract Syntax Notation One

ı IVS: The in-vehicle system is an in-band modem which consists of a
modem that operates full-duplex and allows reliable MSD
transmission to the PSAP via the voice channel through the cellular
network.

ı UL: minimum set of data (MSD):
� 1 MSD contains 3 data parts and 4 muting
periods + preceding synchronization frame
� The MSD is represented by a field of 140 bytes,
appended by a 28 bit CRC code prior to HARQ
FEC encoding.
ı eCall requirements:
� Less than 4 seconds MSD transmission time.
ı DL feedback messages are for example the
START message, NACK if CRC failed, link-layer
ACK (LL-ACK) and higher-layer ACK (HL-ACK)
from the PSAP.
