What is eCall?


Public “eCall” is the future pan-European in-vehicle emergency
call system, expected to be operational beginning in 2015.
–
Will automatically trigger an emergency call for severe
accidents.
–
Creates a voice link to the closest Public Safety Answering Point
(PSAP) and
–
Sends an emergency message (minimum set of data), including
key information about the accident, such as: time, accurate
location, driving direction and vehicle description.
–
Can also be activated manually.
Private Third Party emergency Call are proprietary value-add
services (e.g., Volvo OnCall, GM OnStar, PSA, Fiat, BMW). These
services are expected to continue to exist.

Regulatory Framework for eCall
Mobile Network
Operators
Member States
© GSM Association 2012
• A European Commission Recommendation (8 September 2011)
requires Operators:
• to implement the eCall discriminatory “flag” in all networks;
• to route eCalls to the Public Safety Answering Points;
• to handle eCalls as any other 112/E112 emergency call.
• A European Commission Recommendation (8 September 2011)
requires Member States
• To define Emergency Call infrastructure to receive the eCalls,
• To communicate the most appropriate public safety answering point to
route eCalls and
• to report to the Commission on the implementation status by 31 March
2012.
• Common specifications for Public Safety Answering Point (PSAPs)
within the framework of the ITS Directive are expected to be issued by
12/12, which will ensure emergency centres and rescue services are
equipped for processing the data transmitted by the eCall.
Regulatory Framework for eCall
Automakers (OEMs)
© GSM Association 2012
• Vehicle Type Approval Legislation is expected to be issued by
12/12 to ensure that all new cars in 2015 will have to be equipped
with eCall devices complying with agreed European standards
(already approved by CEN and ETSI).
Member State Progress Reports

19 Member States have communicated to the European
Commission their evaluations of the readiness for eCall
Deployment
–
6 Member States indicated that the Commission Regulation for
Operators was not sufficient to guarantee successful
deployment of eCall, in particular:
•
Italy
•
Romania
•
Greece
•
Sweden
•
Slovakia
•
Czech Republic
–
Austria indicated that they were not sure if a regulation was
necessary
–
Denmark Indicated that Operators were refusing to Implement
the eCall Flag



eCall uses normal voice call emergency (TS12) set-up message
The Emergency Category field is set to either
–
–

This can be used by the MSC to route the eCall to a different number
than normal emergency calls
–
–
–
–
Confidential
Manually initiated eCall
Automatically initiated eCall
E.g. specific eCall PSAP, specific modem/answering point, filtering point
etc
Allows manually and automatically initiated eCalls to be differentiated
Routing requirement should be defined by national administrations
Note: the eCall flag is not sent beyond the MSC; the indication is based
on the Called Number in the ISUP (or equivalent) signalling
14
eCall Dormant SIM - motivation

In-vehicle devices, by their nature, can generate significant volumes of
mobility signalling

at switch-on/switch-off, change of location area, MSC etc

signalling is generated in both home and visited network

eCalls are made very rarely

Operators raised concern about the impact of this signalling
Confidential
15
eCall Dormant SIM - standards

3GPP (Release 8) has introduced an eCall-only mode:

An eCall-only UE (User Equipment) is in a dormant state (“eCall
INACTIVE”) until an eCall, test call or reconfiguration call is made



The UE shall continue mobility management procedures after an eCall
call (or reconfiguration call) has terminated



to allow the Callback (or OTA reconfiguration)
for a period of 12 hours, then UE returns to “eCall INACTIVE” state
It shall be possible for the network operator to reconfigure (unrestrict) an
eCall-only UE so that it can access subscribed services (and to restrict a
previously unrestricted UE)

Confidential
The UE is ‘listening’ (a cell is selected), but network registration is not done
until the call is made
No location update, periodic update etc
This is the reconfiguration call above
16
eCall dormant SIM – USIM configuration


The device implements the e-Call Only dormant state functionality
The USIM configuration determines whether the device behave as eCall-only
device

the device reads the configuration information from the USIM


The USIM



indicates whether eCall is available, and if only eCalls are supported, or both
eCalls and normal calls
stores test and reconfiguration numbers
USIM reconfiguration is needed to:


Confidential
The eCall configuration is only specified for the USIM; It is not specified for the SIM (the
SIM specification was frozen in 3GPP Release 4)
reconfigure an eCall-only capable UE to allow access to additional services
restrict an eCall-capable UE to allow access to eCall only
17
eCall dormant SIM - Implications and considerations




Confidential
Will there be eCall-only devices?

Or, do operators require that there are eCall-only devices?
What will be the mechanism for controlling the eCall-only mode?

USIM, or proprietary?

If USIM, USIMs for eCall need to be configured correctly

If proprietary, how does operator ensure correct behaviour?
Need to define the reconfiguration process that is triggered by the reconfiguration call

who is involved, and with what role?
What happens if ignition is switched off after a reconfiguration call but before
reconfiguration is complete?

depends on reconfiguration method
18
Future of eCall transport solution


Current eCall transport solution is specified for GSM and UMTS
ETSI MSG#29 (in March 2012) agreed a new work item on migration
of eCall transport that will include the following:
•
•
•
•
–
–
Target for MSG approval of the deliverable is 31/3/2013
In addition, MSG#29 agreed a proposal for an ETSI Special Task Force
(STF) on migration of eCall transport.
•
Confidential
Assessment of in-band modem solution in case of no use of CS bearers.
Study the adaptation of IMS emergency call and IMS Multimedia Emergency
Service for supporting current and future service required by eCall.
Hybrid CS/IMS solution.
Migration recommendations
This has been approved by the ETSI Board, and is under evaluation by the
European Commission
19
Implementation in MNOs
The eCall standards are just one part….. MNOs also need to consider:



Confidential
SIM cards

Provisioning, reconfiguration, subscription management,
relationship with SIM supplier and vehicle OEMs

HLR provisioning/capacity
Testing

Testing and certification of eCall devices?

Arrangements for periodic in-the-field testing?
Numbering resources – IMSI and MSISDN
20
Summary



eCall standards are complete
EC have issued recommendation to Member States to ensure MNOs
implement the eCall flag by end 2014
There are implementation aspects beside the standard itself
–
Confidential
Is there benefit in MNOs discuss some of these aspects collectively?
21
eCall implementation –
Ways and reasons to support
Date : 13th September 2012
Final Version : 1.0
CONFIDENTIAL
Support of eCall at the MNO
1. The eCall flag
– Necessary for all European MNO’s.
– The eCall flag need to be implemented according to the specification to be
able to transfer the eCall to the correct PSAP.
– The eCall flag are 2 bits of the “emergency category”.
– eCall flag needs to be implemented before member states can receive/route
eCalls to a PSAP.
2. Dormant SIM
– Applies only to MNO’s that issue SIM card embedded in eCall systems used in
vehicles.
– The Dormant SIM itself plus the update of them need to be supported.
– Dormant SIM is a SIM that is able to tell the GSM terminal to activate
dormant mode.
– If a SIM is not dormant it will signal all the time when it moves and also when
it is not moving through its “Location Updates” and “Periodic Location
Updates”.
Why routing is necessary? Country- PSAP Setup variety

eCall Deployment on top of the legacy infrastructure
►
►
►
►
►
The actual end-to-end network topology is more complex than in the
theoretical architecture
In most EU countries eCall network infrastructure extends the legacy
infrastructure for public E112 service
Most of EU Member States currently adopt a topology consisting of a
network of several PSAPs geographically distributed over the country
(typically at either regional or provincial level)
When a legacy infrastructure exists, each PSAP is typically specialized (e.g.
police, fire brigade, emergency rescue) and operated by a different body
Different roadmaps exists for the actual deployment depending of the PSAP
model adopted at national level

eCall routing scheme
In order to route the eCall to the designated PSAP some additional parameter would be
needed in the ISUP, but this is not feasible  the proper routing is achieved by means of a
dedicated format of the Called Party Number field
The format adopted to deliver the 112 emergency calls (E112 service) was :
C97 0XYZ 11x 9 OP_ID
With a similar mechanism, the following routing number has been proposed and agreed for
the Italian routing of the ecall:
CXX 0XYZ 112 Y OP_ID
CXX = RgN; XX=96 is the value that has been proposed and accepted
0XYZ = origin district of the incoming eCall
112 = unified number for the eCall
Y = type of e Call : Y=0 automatic eCall; Y=1 manual eCall
OP_ID = Operator ID : code of the mobile network

Process
►
►
►
Fragmented deployment  need to build on top of legacy infrastructure to save costs of the
infrastructure deployment/adaptation
Technical
►
►
►
►
eCall service deployment in Italy requires some reorganization of the safety/emergency
management process at national level.
The current standards for the PLMN enable an adequate initial deployment. Qualification
tests of the new mobile network features have been successfully completed by TI and the
deployment in the Pilot area (Varese) is on-going
Impacts on signaling processing and routing in PSTN requested the adoption of a custom
solutions at national level
Scalability and future technology compliance need to be achieved (through continuous
standard evolution)
Costs & Business Models
►
Models to support national deployment & operational costs to be exploited
►
Integration with other ITS public utility and/or commercial services

Conclusions
►
►
►
►
►
►
►
eCall is entering pre-operational phase
From a mobile/fixed telco operator perspective technology is mature but the end-toend system will have to be able to support modular evolution and upgrades
TI started evaluating the needed network upgrades (e.g. eCall discriminator) as soon
as the required features has been made available by network technology vendors
FNO’s need country specific solutions regulated by national government for properly
routing the eCall coming from different MNO’s to the designated PSAP
HeERO Pilot Project is prooving a suitable tool for assessing the technical and
deployment issues in a realistic environment with the involvement of all needed
stakeholders
Initial deployment costs in the infrastructure (PSAPs and telco mobile and fixed
networks)  need to guarantee significant level of adoption and service availability
from day one
Need of suitable models for making initial deployment and daily operation
economically sustainable for all involved parties

Introduction
• All new “type approved” cars in the EU from 2015/latest
early 2016
• All member states to draw up detailed rules for public
mobile network operators.
• All mobile network operators in Europe to:
• Support of the eCall like any 112 call
• Implement the eCall discriminator
(by 31 December 2014)
• This regulation, which will change the landscape in the EU,
47
will result in wide-scale usage of connected vehicles
47 Vodafone GSMA webinar| September 2012
Mandates recommend embedded
eCall
• A growing number of telematics mandates (EU, Russia,
Brazil). All of these mandates are expected to require (or
strongly recommend) embedded telematics
• Note. “Although the EU’s mandate technically does not
specify what type of connectivity should be used for eCall,
the EC has already strongly spoken out against nonembedded systems such as Bluetooth-based eCall. The EC
has highlighted concerns that the reliability of Bluetoothbased solutions would be compromised during a crash, or
that the driver may not have connected the smartphone to
the car before the crash.”

Embedded – Advantages &
Disadvantages
Advantages:
Disadvantages:
• Copes with environmental requirements such as
temperature and vibration etc
• Does not require user set-up
• Best communications performance, using single
antenna
• Immediate hardware costs
to be taken into
consideration
• Robust and reliable
• Lack of problems due to incompatibly, interoperability
• Automaker can specify the internal modem and antenna
Automaker can guarantee that the service and
associated HMI is appropriate for use in-vehicle (and
control the service's availability)
• Operators could develop specific commercial offers
for further connected car services
The eCall
regulation
will help to
remove this
barrier
Embedded gives the best performance for safety (E-Call)
It is the preferred route of legislators

Network requirements and roadmap for
commercial deployment of eCall
Anders Fagerholt, Ericsson
MSC eCALL upgrade
› Rather straight forward, a 112 call with the bits MIeC or
AIeC flagged is routed to a defined number at the nearest
PSAP that is equipped with an InBand modem pool.
› Market customizations have been developed for 3
networks and can be developed and delivered as a
customization from MSC R14.1 onwards.
› eCall is planned as an Optional New feature in a coming
MSS release.
Ericsson Internal | 2012-09-04 | Page 54
Network requirements
› eCALL was not supposed to put ANY requirements on the
GSM/UMTS network (other than the eCALL routing)
› Results from HeERO Sweden in 2 networks show that
when a voice call can be set up, eCALL mostly works.
› In two Swedish networks we see a reliable MSD transfer at
+3dB signal level above voice call threshold, ( but eSMS is
reliable -3dB below voice threshold!).
Ericsson Internal | 2012-09-04 | Page 55
HeERO drive test in Sweden
Around 2600 km were driven in different environments
(rural and highway in South- and Middle-Sweden),
nearly 1000 eCall attempts and about 2800 MSD transmission
attempts were made.
The overall success rate ranges in these Test Sessions from 100%
down to 75%, mostly depending on sufficient mobile coverage for
setting up an emergency call.
Ericsson Internal | 2012-09-04 | Page 56
Future perspective
› The standardization of echo canceller disabling is not
finished and it has not been tested in HeERO 1 or 2.
› eCALL is defined for GSM and UMTS networks, not for
data networks like LTE and VoIP
› Cars rolled out 2015 will still be rolling 2030 and require
service continuity?
› In band modem will be a cost driver in the network
evolution
– Additional testing and verification on every step of voice path
evolution and in every release!
– Will it put restrictions on speech path evolution?
