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

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.

eCall signaling procedure:

Initiation: In the case of an accident, IVS establishes an automatic

emergency call => start messages are sent continuously (max. 5x)

Send-MSD: PSAP receives emergency call and triggers MSD

transmission (PULL mode), continuously sends start until

it detects the first incoming sync frame.

MSD-tx: IVS sends sync frame (dotted) after 3 successfully decoded

START messages, MSD RV0 is sent, then MSD RV1

(since IVS first receives NACK, but discontinued after receiving LL-ACK)

NACK: PSAP detects uplink sync and continuously transmits NACK

LL-ACK: PSAP tries to decode MSD after complete reception of RV0,

and after each data part of subsequent RVs

AL-ACK: After CRC success, PSAP sends 3 ACK messages and

then stops transmission => voice channel is un-muted.

Play tone: To test the voice channel in the R&S PSAP implementation

a 1kHz sine tone is played.
