ETSI ACTIVITIES ON CRITICAL COMMUNICATIONS
Adrian Scrase, ETSI
GSC-18 Meeting, 22-23 July 2014, Sophia Antipolis, France
What Standards does ETSI produce?
ETSI prepares standards which:
• Help prevent emergency situations from occurring
• Help alert those who need to be informed when an emergency
situation has occurred
• Help manage emergency situations once they have occurred
Prevent
Alert
Manage

Cooperative Intelligent Transport Systems
Wireless communications-related applications intended to increase travel
safety and reduce road fatalities and injuries
• Providing information on vehicles, their location and the road environment
• Allowing vehicles to communicate with each other and/or with the infrastructure
Public Safety organizations receive vital information from vehicles
Cooperative ITS can be used on-board emergency vehicles
Main current features of co-operative road safety are
• Vehicle status or types warnings (e.g. emergency electronic brake lights, emergency
•
•
•
vehicle warning, vulnerable road user warning)
Traffic hazard warnings (e.g. stationary vehicle warning)
Dynamic vehicle warnings (e.g. pre-crash sensing warning)
Collision risk warning

Over 50 Use case
scenarios
High Speed Railway Communication
Global System for Mobile Communications – Railway (GSM-R)
• This standard defines the use of GSM as a network for rail transport
infrastructure operators
• It is used for communication between trains and railway regulation
control centres
• GSM-R is implemented worldwide and has been mandated for use in
the EU as the standard for high speed railway communications since
1997
• LTE-R may be considered in a near future
Standard No.

Road Safety
eCall: automated call from vehicle to emergency services, based on 112
and including a Minimum Set of Data (MSD) such as location, vehicle type,
etc
Standardization work complete (3GPP, ETSI, CEN) and stable, now in the
implementation phase:
• European eCall Implementation Platform hold regular meetings
• New Europe to lead? High readiness in Romania, Croatia, Czech Republic
European Commission has:
• Mandated Member States to upgrade Public Safety Answering Points (PSAPs) for eCall
• Formally recommended mobile operators to support eCall
• Made eCall necessary for type approval of vehicles from October 2015
GSC-18, 22-23 July 2014, Sophia Antipolis
7
Maritime Safety
The Global Maritime Distress and Safety System (GMDSS) is an integrated
communications system using satellite and terrestrial radio to ensure
coverage
The main GMDSS features for alerting are:
• Emergency call: « classical VHF »
• Digital Selective Calling (DSC): press red button during 5s to send an automatically
•
formatted distress alert (including location, Maritime Mobile Service Identity (MMSI) of
the boat) to the Coast Guard or other rescue authority via MF/HF/VHF maritime radio
systems
Emergency Position Indicating Radio Beacon (EPIRB) is automatically sending a message
via satellite to an authority, when a ship is sinking
ETSI is active in a number of activities related to GMDSS
EN 300 338-6
Relating to the Global Maritime Distress and Safety
System(GMDSS),
EN 303 098-1

Automatic Identification System(AIS) transmissions
GSC-18, 22-23 July 2014, Sophia Antipolis
8
Non-voice Emergency Communications
People with disabilities need to successfully access emergency services
ETSI has produced a specification on “Total Conversation” whereby
emergency services authorities may be alerted using video and real-time
text in addition to audio (TS 101 470)
SMS for emergency calls
• Delivery inconsistencies and delays are a factor
• May lead to an increase in hoax calls
• A number of European countries have implemented SMS for hearing impaired
•
people, but under a pre-registration scheme
The future of SMS emergency calls in Europe is at present uncertain
GSC-18, 22-23 July 2014, Sophia Antipolis
9
Enhanced Caller Location
For emergency calls using traditional networks (fixed or mobile) the caller
location information is readily available. This is not the case for VoIP
services (such as Skype).
ETSI is responding to the European Mandate (M/493) in support of the
location enhanced emergency call service
• The aim of the mandate is to standardize the determination and transport of caller
•
location information for VoIP including a single functional model, the necessary
interfaces and protocols
This includes routing of the emergency call to the most appropriate PSAP and
transmission of the location information of the caller
Work is underway
• A functional architecture (e.g. identification of all interfaces) to determine the
•
standardization work needed has been produced (ES 203 178)
The definition of protocols, based on the previous deliverable, has started (ES 203 283)
GSC-18, 22-23 July 2014, Sophia Antipolis
10
Public Warning Systems
The Public Warning System (PWS) is an emergency service that
delivers alert messages to mobile devices using the Cell Broadcast
Service (CBS)
PWS was first defined to cope with natural disasters such as
Earthquakes and Tsunamis
It has now been generalized to cover other emergency situations
Cell Broadcast uses a dedicated signalling channel, different to that
used for voice/data, and therefore not affected by network
congestion
The European implementation is called EU-Alert
GSC-18, 22-23 July 2014, Sophia Antipolis
11
EU-ALERT
European requirements:
• Different interface languages have to be taken into
•
•
•
•
account
No regulatory regime apart from an amendment
of the Universal Service Directive in which the
Members States are asked to implement PWS
When implemented, the letters EU will be
replaced by characters identifying a particular
country , such as NL-ALERT for the Netherlands
The Netherlands is the first EU Member State to
start EU-ALERT trials and will now move to
implementation
UK, France, Belgium, Spain & Greece are currently
investigating the possibility of deploying EUALERT

Digital Mobile Radio
Digital Mobile Radio (DMR) is a technology standardized by
ETSI and divided into three tiers:
• Tier 1: License-exempt: direct mode, no infrastructure for consumers, and
•
•
short range professionals
Tier 2: Licensed conventional: direct mode including infrastructure for
business applications
Tier 3: Licensed trunked: for public safety and mission critical users
DMR was intended as a direct replacement of analogue PMR
• It started with DMO but now also includes trunking capabilities
• Further work needed to ensure interoperability
GSC-18, 22-23 July 2014, Sophia Antipolis
15
Satellite Emergency Communications
ETSI is preparing standards in the area of satellite
emergency communication, in particular involving
broadband services.
Scenarios covering the set-up of a temporary
emergency communication cell based on Wifi,
VHF/UHF, WIMAX, GSM or TETRA which is then
linked/backhauled to the permanent infrastructure
by means of a bi-directional satellite link
This will form ETSI’s response to the European space
mandate (M/496) to develop standards for the space
industry, more particularly concerning disaster
management

Conclusions
The standardization of Critical Communication systems is
essential…
…and so is the participation of the wider Critical
Communications community in preparing those standards
Better knowledge sharing and collaboration is required
between all stakeholders
Global solutions offer significant economy of scale advantages
Intelligent use of modern ICT technologies will help save lives
But, Prevention is always better than cure…..
