Foreword
This Technical Report (TR) has been produced by ETSI Special Committee Emergency Communications (EMTEL).
The present document is the first of a set of deliverables covering the communication needs of individuals and
authorities in emergency situations, as identified below:
• ETSI TR 102 180: "Emergency Communications (EMTEL); Basis of requirements for communication
of individuals with authorities/organizations in case of distress (Emergency call handling)";
• ETSI TS 102 181 [i.20]: "Emergency Communications (EMTEL); Requirements for communication between
authorities/organizations during emergencies";
• ETSI TS 102 182 [i.21]: "Emergency Communications (EMTEL); Requirements for communications from
authorities/organizations to individuals, groups or the general public during emergencies";
• ETSI TR 102 410 [i.22]: "Emergency Communications (EMTEL); Basis of requirements for communications
between individuals and authorities whilst emergencies are in progress".
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The provision of Emergency Telecommunications is one of the most important duties of a public authority towards
individuals present on its territory. Individuals, Authorities and Emergency response teams therefore have a need for
dedicated, high quality communication systems operating at all times.
In the past this area of communications has been developed, provided and organized by the national
telecommunications operators and the national safety and security agencies/organizations. In today's deregulated and
liberalized telecommunications market, operators of public telephone networks have the obligation to provide this type
of communication under their regulation on a European and national basis.
At European Union level, a common emergency call number (112) is applied. In certain countries it may co-exist with
former numbering codes maintained by the national authorities and dedicated to more specific usages or needs. The
proposals of the present document are primarily focussed towards the deployment of a consistent service based on the
112 number; it is a matter of national decision and initiative to apply them for the other numbers in use for emergency
calling.
ETSI

---------------------- Page: 5 ----------------------
6 ETSI TR 102 180 V1.5.1 (2015-07)
The present document should be read as a contribution to the harmonization of the use of E112 by the emergency and
disaster response agencies. Based on inputs from all parties in the Emergency Service User Community involved in
providing such services, and after due adoption, the requirements expressed should be distributed to the relevant ETSI
Technical Bodies, who are requested to take this material into account when amending existing, or drafting new,
deliverables for services and systems to support Emergency Communications. However, the present document can also
be made available to other organizations and mainly at European Commission level as a contribution to their work, as
the case may apply.
The present document catalogues the requirements on Emergency Call Handling as seen by the Emergency Service
User Community. Clause 4 sets out the requirements on the emergency call service itself, including: service provision,
end-user expectations and related requirements, terminal equipment, the call originating network, interconnection
between networks, the functionality on the PSAP (Public Safety Answering Point), functionality on involved and transit
networks, and network management requirements. Clause 5 outlines the benefits of a European-wide interface between
operators and Public Safety Answering Points. Clause 6 lists the special requirements when making emergency calls by
disabled, elderly and young users. Clause 7 refers to the need for special requirements for emergency calls in a foreign
language. Where clause 8 quotes the data protection provisions in the case of an Emergency situation and clause 9
refers to the need for future considerations in further networks still to be defined. Clause 4 is the main clause describing
the basic working of the service and its components, with a catalogue of the types of access to be considered and their
special networking considerations.
NOTE: A specific mention may be made about the processing of the location information to be sent with the
emergency call as the Directive 2009/136/EC [i.27] and the Directive 2009/140/EC [i.26] have significant
changes from the Directive 2002/21/EC [i.3] and the Recommendation C(2003)2657 [i.2] of 25/07/2003.
Additionally, the emergence and development of alternative offers based on technologies such as VoIP (Voice over
Internet Protocol) is creating critical situation linked to the definition of the service offered. There is a need to
consolidate the comprehensive provision of the emergency call (including short numbering, adequate origin-dependent
routing, no charge and transmission additional information) as a reference requirement in the planning of future
systems.
Consideration is also given to the use of SMS, in conjunction with an emergency call, and the emerging applications
which combine different technologies (e.g. Multimedia Message Services or GPS).

1 Scope
The present document gives an overview of the requirements for communication from individuals to authorities and
organizations in all types of emergencies. It collects operational and organizational requirements as a basis for a
common 112 service, including location information (E112). Although many of the requirements collected from
network operators, service providers (e.g. emergency response organizations) and users relate to national public policies
and regulation, there are a number of service and technical aspects which are better dealt with on the European level to
ensure harmonized access and services over Europe and effectiveness by user increased awareness by using
standardized solutions.
The essence of an emergency call is to establish a direct and real time means of conversation between the calling party
and an officer, in a Public Safety Answering Point, in charge of bringing assistance or organizing response. However,
the scope of the present document also encompasses various types of services that can bring an added value to this basic
scenario or add new scenarios, such as transmission of data to extend the information made available to the PSAP's
agent or to facilitate access of people suffering disabilities or impairments.
The present document also collects already established requirements for EMTEL and gives guidance on how to find the
standardization work published or ongoing. The present document also identifies the areas needing particular attention
from the experts and refers to identified documents in preparation in SDOs (Standard Development Organizations).
The present document outlines the basis for technical, operational, organizational or regulatory requirements.
The present document is primarily applicable to ETSI technical bodies for the defining of services and specifying
technical solutions.
Requirements for emergency calls of a private nature (e.g. vehicle/road assistance) and directed to an emergency service
provider not being an emergency service provider recognized by a government are not covered by the present
document.
It is anticipated that the present document will be maintained, by taking in line with developments at regulatory level
and more specifically within the CoCom (Communication Committee for the Electronic Communications Directives) at
the European Commission (EC) level.
