1. ETSI Technical Committee TCCE TETRA and Critical Communications Evolution Seminar "Education about Standartisation for SMEs Sofia, 14th March 2016

2. Why TETRA and CRITICAL COMMUNICATIONS Evolution ? TErrestrial Trunked RAdio (TETRA) is a digital trunked mobile radio standard developed to meet the needs of traditional Professional Mobile Radio (PMR) user organisations such as:PMR Public Safety, Transportation, Utilities, Government, Military, Commercial & Industr, Oil & Gas from single site local area coverage to multiple site wide area national coverage.

3. Some unique PMR services of TETRA are:  Wide area fast call "all informed net" (one-to-one, one-to-many, many-to-many)  Direct Mode Operation (DMO) allowing "back to back" communications between radio terminals independent of the network  High level voice encryption to meet the security needs of public safety organizations  An Emergency Call facility that gets through even if the system is busy  Full duplex voice for PABX and PSTN telephony communications Besides meeting the needs of traditional PMR user organisations, the TETRA standard has also been developed to meet the needs of Public Access Mobile Radio (PAMR) operators.

4. ETSI TCCE have responsibility:  For the provision of user driven standards for authority to authority secure voice and data services and facilities over broadband and narrowband air interfaces.  To collect and specify requirements from relevant stakeholders such as the Emergency Services, Government, Military, Transportation, Utility and Industrial organizations as well as Public Access Mobile Radio (PAMR) Operators.  To maintain and develop the existing TETRA standard.  For ETSI deliverables (in whole or in part) dealing with both TETRA and mobile broadband critical communications.  To ensure that work programmes within ETSI TC TCCE are co-ordinated with other European and International Standards making bodies to avoid duplication of deliverables.

5. TCCE working groups  TCCE WG01 – User Requirements/Services. Working Group 1 is responsible for producing the User Requirement Specification (URS) for TETRA and Critical Communications Evolution. This is a mixture of extensions to TETRA functionality and requirements for operation of critical communications over a broadband link such as LTE technology. The deliverable shall be a set of Technical Reports (TRs) which will be used by all the other TC Working Groups as a basis for their work on drafting standards. The main role of WG1 is seen as being "the voice of the TETRA and Critical Communications Market", with the objective to collate what are often conflicting requirements from different user entities, such as Public Safety users, commercial users, network operators, etc., into one or more coherent and generic URSs. Chairman Malcolm QuelchMalcolmQuelch  TCCE WG03 – Air Interface and Network Protocols. The objective of the Terms of Reference for TC TCCE WG3 is to maintain existing TETRA deliverables and produce additional sets of ETSI deliverables in order to enhance and maintain TETRA standards and specification as needed for TETRA implementations. Chairman Jukka VialenJukka Vialen

6. TCCE working groups  TCCE WG04 - High speed data. To create Standards and supporting documentation as needed for provision of mission critical services over broadband bearers, and for the evolution of TETRA High Speed Packet Data and voice services as per current TC TCCE.  Specification of mission critical broadband bearer services  Standardisation of mechanisms to provide mission critical voice and data services over broadband bearers  Integration of existing TETRA data and voice services with those services operating over broadband bearers  Continual improvement and evolution of TETRA 1 and TETRA 2 (TEDS) data services to improve efficiency and performance  Reports where relevant concerning the high speed and broadband data environment, such as spectrum requirements  Chairman David Chater-Lea David Chater-Lea

7. TCCE WORKING GROUPS  TCCE WG05 – Voice coding. Selection and standartization of additional speech codec(s) for TETRA, to enable intercommunication between TETRA and other 3G networks without transcoding, and to provide enhanced voice quality for TETRA by using the latest low bit rate voice codec technology. Chairman Michael StreetMichaelStreet  TCCE WG06 – Security. WG6 will be responsible for all issues relating to the standardisation of Security, Lawful Interception and Fraud & Misuse (prevention) within TC TETRA and Critical Communications Evolution. Chairman Trevor EvansTrevorEvans  TCCE WG08 – Of-network services. Direct Mode Operation – DMO. Interim Chairman Jukka VialenJukka Vialen

9. The Future  Is Integrated Critical Communication A Must For The Modern Society?  Why Broadband – global profound public safety cases indicate the necessity of broadband for the modern society.  Integrated services (voice, data and video) are unified into LTE with the open, collaborative industry.  LTE-based critical communication can intelligentize the public safety.
