Who needs to communicate?

2 © ETSI 2014. All rights reserved

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

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

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


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 linkThis will form ETSI’s response to the European space mandate (M/496) to develop standards for the space industry, more particularly concerning disaster management

LTE global success

LTE is the state-of-the-art terrestrial cellular broadband standardFirst phase standards completed in 2008, with LTE-Advanced following in 2011Developed by 3GPP (SDOs from Europe , North America, China, Japan, and Korea)Adaptable to wide range of radio bandsMore than 100 countries have live LTE networks (approx 200M subscriptions)All user applications, including voice, supported over IP

http://www.3gpp.org/ftp/Information/WORK_PLAN/Description_Releases/

Enable locally routed communication• for “nomadic” eNodeBs operating

without backhaul connectivity • for “regular” eNodeBs experiencing

temporary loss of backhaul connectivity

Isolated E-UTRAN operation (FS_IOPS)

Cell Site

Network

Requirements to improve the E-UTRAN, EPC and application-layer functionality, including applications supported by UEs and external network elements (e.g. Application Servers) delivering Push To Talk functionality for Mission Critical voice for LTE.Requirements include:• Floor control aspects• Group and individual PTT calls• Associated services including talker ID, location and

emergency alerting• Interworking with other voice systems including

PSTN and LMR/PMR

Mission Critical Push-to-Talk (MCPTT)

Dedicated Public Safety Spectrum?

EC 700 MHz Mandate• “to develop harmonised technical conditions for the 694-790 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 102 628) 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


Participation in 3GPP

To ensure careful consideration for interworking and migration• TETRA -> LTE (voice) migration / co-existence

Liaison statements are a poor substitute for knowledgeable people in the meeting To preserve meaningful reuse of commercial LTE technologySo that 3GPP can balance priorities of all members• Contributions drive the work

GLOBAL COOPERATION


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


Conclusions

The standardization of Critical Communication systems is essential……and so is the participation of the Critical Communications community in preparing those standardsBetter knowledge sharing and collaboration is required between all stakeholdersGlobal solutions offer significant economy of scale advantagesModern technologies will lead to more efficient use of the radio spectrum Prevention is better than cure…..


And finally...a date for your diary

ETSI will convene a Workshop on Emergency Communications
