Introduction

• ETSI TC TCCE (ex TC TETRA) changed its title and
  ToRs in 2013 in response to users needs to have a
  technical body with the mandate to develop
  critical communications broadband standards as
  well as continuing the development and
  maintenance of TETRA standards. This was in part
  to be more inclusive and not confine any
  interfacing to narrowband legacy technologies to
  TETRA
• TCCE works closely with the TCCA (Tetra and
  Critical Communications Association) particularly
  with the generation of requirements. This has
  given us much wider access to users and operators
  than would have been possible within ETSI
• TCCE have been working on critical communications
  broadband standardization since 2010 and the work
  is described in later slides

Rationale

• It is our belief that critical communications
  should be provided as fully as possible at the
  application layer, so that standard products can
  be used, allowing wide choices of networks and
  terminals. Real competition engenders innovation
  and best prices
• It is in the best interests of users, operators
  and industry if standards are produced as
  efficiently and quickly as possible. Delay leads
  to the adoption of proprietary solutions with
  consequent disadvantages
• There are certain irreducible requirements that
  must be standardized if viable critical
  communications systems are to be developed.

Early TCCE BB standardization work

• Production of a service requirement document
  describing the spectrum needed for critical
  communications broadband systems ETSI TR102 628
• Evaluation and quantification of BB functions in
  terms of spectrum requirements, performance and
  network from the LEWP matrix of requirements
• Original concept was to implement TETRA
  signalling over BB systems to provide CC
  functionality
• Concept then changed and LTE was accepted as the
  bearer of choice and other narrowband PMR/LMR
  technologies embraced

6
User Requirements Specification

• Comprehensive and consolidated user requirements
  specification was required
• These are the formal reference documents from
  which the technical standards are developed
• Two documents have been produced
• ETSI TR 102 022-1 V1.1.1 Mission critical
  Broadband Communications Part 1, Requirements
  published in 2012
• Takes many inputs from TCCA, LEWP, transport
  for London, Rail, Utilities
• Maps data requirements against the capabilities
  of TETRA, TEDS and LTE
• Describes that the highest priority for police
  across Europe is for video at disaster
• ETSI TR 102 022-2 V0.0.6 Mission critical ETSI TR
  Broadband Communications Part 2 Critical
  Communications Application, publication imminent
• Describes the reasoning behind the method of
  creating critical communications networks by
  using aplication layer interfaces on standard
  netwroks that have e.g Group Comms system
  enablers
• Describes 13 CCA interfaces which have been
  developed in the architectural refernce model
• Describes all required CCA features

7
Study into security mechanisms for mission
critical broadband systems

• A study into security systems appropriate for
  both an underlying broadband system (e.g. LTE)
  and also for applications providing
  mission-critical services, including Group call
  and Direct Mode (ProSe) services
• It has been recognised that there are many
  security features that will be required by public
  safety bodies in addition to those likely to be
  provided by standard LTE and these should where
  possible operate at the application layer
• Stable draft due - March 2015

8
Critical Communications architecture reference
model

• Published as ETSI TR 103 269-1 Critical
  Communications Architecture Part 1 Critical
  Communications Architecture Reference Model
• Describes the reference model for a CCA and the
  various interfaces between the entities that
  provide a CC solution operating over broadband IP
  networks including but not confined to LTE

9
Critical Communications Application mobile to
network interface architecture

• This is the first priority CCA interface
• Output will be an ETSI technical report
  describing the architecture and relevant entities
  for the mobile to network interface of a CCA
  operating over a broadband IP interface
• Stable draft imminent

10
Critical Communications Application mobile to
network interface specification

• Output will be a harmonized ETSI Standard (EN)
  specifying the mobile to network interface of a
  CCA operating over a broadband IP interface
• Stable draft due - March 2015
