2. Who needs to communicate?
There are four scenarios of critical communication:
Between authorities
From individual to authority
From authority to individual
Between individuals
ETSI is addressing:
All four of the scenarios above
In all environments
Involving different stakeholders , such as public safety users, regulators, network operators and manufacturers

3. Why do they need to communicate?
ETSI prepares standards which:
Help prevent emergency situations from occuring
Help alert those who need to be informed when an emergency situation has occured
Help manage the emergency situations once it has occured
Prevent
Alert
Manage

5. DMR
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

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

Critical Communications
only
Also of interest for consumer applications
Proximity services consists of two main elements: network assisted discovery of users with a desire to communicate who are in close physical proximity and the facilitation of direct communication between such users with, or without, supervision from the network. Direct communication means a radio connection is established between the users’ mobiles without transiting via the network. This saves network resources and can also permit public safety communication in areas outside network coverage. Proximity services meet the need for communication among public safety users even if they are not in coverage of the network. In the commercial area proximity services can support features like new modes of social networking, convenient file transfer between devices belonging to the same user and targeted advertising. In the commercial context 3GPP’s standards will ensure that use of licenced spectrum is controllable and billable by the network operator.

15. Group communication enablers
Enable efficient group communication
Dynamic groups with mobile users and dispatchers
Support for large groups (perhaps up to 5000)
Service continuity for transitions between unicast and multicast bearers
Network
Group Call application
server
Dispatcher
Public safety users frequently need to communicate in dynamic groups that might involve both mobile users on the scene and fixed users (“dispatchers”) working in a control centre. Often these groups operate in a “push to talk” mode. Work on LTE group call system enablers will optimize support in LTE for this mode of operation and provide appropriate group management and floor control facilities. Commercial users of group calling include critical communications applications such as operational teams in transport hubs. Improved support for group calling in LTE will expand the opportunity for commercial cellular networks to address this market.
One aspect of group communication still being considered is how much functionality should be “baked in” to the LTE infrastructure and how much should be delivered by non-standardised application servers. The use of application servers will allow different organizations or regions to customize the system operation to their own needs whereas “baked in” solutions may be more efficient and simpler. It is expected that further discussion will take place on how to handle session management for public safety group communication and possible impacts on technology like the IP Multimedia Subsystem (IMS).

19. Dedicated Public Safety Spectrum?
EC 700 MHz Mandate
“to develop harmonised technical conditions for the MHz ('700 MHz') frequency band in the EU for the provision of wireless broadband and other uses in support of EU spectrum policy objectives”
Preparation for WRC-15 where agenda item on requirements for PPDR
ECC CEPT Report 199 on User requirements and spectrum needs for future European broadband PPDR systems
ECC CEPT draft interim report to EC Mandate on 700 MHz that will go for public consultation in 2014
In this report it is noted that LTE technology is expected to be the future technology to meet broadband PPDR needs.
Studies are being carried out in ITU-R WP5A
At ETSI: Publication pending of the joint work between TC ERM and TC TCCE to revise their (TR ) System Reference document on additional spectrum requirements for future Public Safety and Security (PSS) wireless communication systems in the UHF bands
If such spectrum is put in place, European Standards will ensure interoperability of PPDR systems

22. Task Force on emergency communications
A Task Force was set up by the Global Standards Collaboration meeting in November 2011 (GSC#16)
ETSI coordinates this Task Force which involves: ARIB (Japan), ATIS (US), CCSA (China), ETSI (Europe), ISACC (Canada), TIA (US), TTA (South Korea), TTC (Japan) and ITU.
The Task Force delivered a report on public safety communications at GSC#17 (mid May 2013)
The report includes:
A collection of regulatory requirements
A catalogue of existing standards which address “the four scenarios” of emergency communication
Visibility of ongoing standardization work worldwide
Areas where futher standardization is required
Suggestions for global harmonization of standards
Updated report to GSC#18, July 2014 with further regions and countries

23. Conclusions
The standardization of Critical Communication systems is essential…
…and so is the participation of the 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
Modern technologies will lead to more efficient use of the radio spectrum
Prevention is better than cure…..
