Foreword
This Technical Report (TR) has been produced by ETSI Special Committee Emergency Communications (EMTEL).
Introduction
The present document provides an overview of requirement specifications with emphasis on functionality that is
specific for the mobile device in a public warning service. Requirements specifications have generic aspects and
regional aspects. The generic aspects should be specified by 3GPP and the regional aspects by the regional SDO.
A number of EU member states is investigating the possibility to deploy a public warning service in their country. The
Netherlands have taken the lead in a EC funded project on "European Cooperation on Cell Broadcast", after having
announced publicly that the Netherlands will deploy such a service in 2010.
The present document investigates if there is a need for an ETSI Technical Specification for Mobile devices to support a
public warning service.

1 Scope
The present document is an overview of existing requirements and recommendations for mobile devices able to receive
messages used in a Public Warning Service (PWS). It has been prepared mainly with reference to the GSM and UMTS
mobile infrastructure, but any functional requirement can be relevant for other contexts (WiFi, WLAN, etc.)
The result of this overview is an advice on a possible need for an ETSI Technical Specification on Mobile Device
Specifications for a PWS, if this is so decided by a Technical Committee.

4 Background
TS 102 182 [i.1] provides an overview of the requirements for communication from authorities/organizations to
individuals, groups or the general public in all types of emergencies. It collects operational and organizational
requirements as a basis for a common notification service, including targeting of the area to be notified. Although many
of the requirements 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 service
effectiveness through increased user awareness by using standardized solutions.
3GPP WG SA1 conducted a study for requirements for PWS in TR 122 968 [i.2], where the EMTEL
specification [i.1], requirements from Japan for ETWS and requirements from the US for CMAS were used as input.
From this study, SA1 delivered a specification with PWS Requirements in TS 122 268 [i.3]. This specification covers
PWS in general, where both ETWS and CMAS are regional adaptations of PWS.
4.1 Mobile Device requirement specifications
PWS Requirements in TS 122 268 [i.3] contains a number of mobile device specific requirements of a general nature.
Specific mobile device requirements for CMAS have been specified by ATIS and TIA in J-STD-100 [i.4]. Specific
mobile device requirements for ETWS in English are unknown.
4.2 Draft ITU-T recommendations
The draft ITU-T recommendations [i.5] and [i.6] address PWS issues with the notion that PWS could be deployed with
legacy mobile devices, since many ITU member states have a cash poor citizenship.
Specific issues that these recommendations address are:
• Types of messages, such as alert messages and advisory messages.
• Support for roaming.
• Support for multiple languages.
In more detail a solution for these issues with Cell Broadcast has been described.
4.3 EU Project Position Paper
The EC funded project "European Cooperation on Cell Broadcast" was initiated by the Ministry of Interior and
Kingdom Relations of the Netherlands. The purpose of the project was to share knowledge and experiences and
identification and standardization of (technical) requirements among the participating EU member states.
A result of the project is the EU Project Position Paper [i.7]. The content of this paper is supported by a number of
member states. See annex A for an example of the supporting letter from the Dutch government [i.8] and an overview
of EU member states that signed the support letter.
The EU Project Position Paper details a number of specific mobile device requirements.
5 Mobile Device requirements from TS 102 182
TS 102 182 [i.1] lists specific MMI requirements in clause 5.2.9 of that document. Clauses 5.1 and 5.2 list those
requirements.
ETSI
9 ETSI TR 102 850 V1.1.1 (2010-08)
5.1 MMI Requirements
5.1.1 Recognizing the emergency message
[501] An emergency alert message should be immediately recognizable. (Emergency messages shall be
specifically recognizable as being an emergency message that cannot be mistaken for an ordinary
message.)
5.1.2 Displaying the message on mobile phones
[502] The emergency warning message should stay on the display regardless of the user setting, until the
message indication is cancelled by the user. It shall be possible for the user to review the message
at a later time.
6 Mobile Device requirements from TS 122 268
TS 122 268 [i.3] lists specific PWS-UE requirements in clause 4.6 of that document. Clauses 6.1 and 6.2 list those
requirements.
6.1 PWS-UE Requirements
6.1.1 General Requirements
[601] PWS-UEs shall only be required to receive and present Warning Notifications in languages as
presented by the Warning Notification Provider.
[602] There shall be no requirement for language translation in the UE.
[603] It shall be possible for the Warning Notification to be displayed on the PWS-UE upon reception
and without any user interaction.
[604] It shall be possible for users to configure the behavior of a PWS-UE with regard to Warning
Notification alerting and should allow at least volume adjustment.
[605] The PWS-UE shall support a dedicated alerting indication (audio attention signal and a dedicated
vibration cadence) and be distinct from any other device alerts and restricted to use for Warning
Notification purposes.
[606] The alerting indication for a specific Warning Notification shall continue until suppressed by
users' manual operation (e.g. by pushing keys). The frequency and duration of the continued
alerting indication is mobile device implementation specific. This shall not suppress the alerting
indication for subsequent Warning Notifications.
[607] The PWS-UE shall automatically suppress duplicate notifications. A duplicate is a repetition of a
previous notification as determined by unique parameters.
[608] The PWS-UE shall not support any capabilities to forward received Warning Notifications, to
reply to received Warning Notifications, or to copy and paste the content of Warning
Notifications.
[609] PWS-UEs should have the ability to present previously displayed Warning Notifications if
requested by the user.
[610] PWS-UE shall be able to support concurrent reception of multiple Warning Notifications.

10 ETSI TR 102 850 V1.1.1 (2010-08)
6.1.2 Support of non-Warning Notification capable UEs
[611] Support of non-Warning Notification capable UEs is subject to regulatory requirements and/or
operator's policy.
6.1.3 Battery Life of PWS-UE
