Prizemni snopovni radio (TETRA) - Tehnične zahteve za neposredni način delovanja (DMO) - 4. del: Radijski vmesnik tipa 1 za ponavljalnike (repetitorje)
Večdelni dokument EN 300 396 določa neposredni način delovanja (DMO) prizemnega snopovnega radia (TETRA).
Določa osnovni radijski vmesnik, medsebojno delovanje skupin neposrednega načina (DM) prek ponavljalnikov in medsebojno delovanje s sistemom prizemnega snopovnega radia, ki podpira govor in podatke (V+D), prek prehodov. Poleg osnovnih nosilnih in telekomunikacijskih storitev določa tudi varnostne vidike neposrednega načina delovanja prizemnega snopovnega radia in storitve, ki jih podpira.
Ta del se uporablja za radijski vmesnik za ponavljalnike neposrednega načina delovanja (DM-REP) prizemnega snopovnega radia in vsebuje specifikacije za fizično plast, plast podatkovne povezave (DLL) in omrežno plast v skladu z modelom ISO.
Specifikacije iz tega dokumenta se uporabljajo za ponavljalnik neposrednega načina delovanja kot samostojno enoto za podporo enega klica na radijskem vmesniku (ponavljalnik neposrednega načina delovanja tipa 1). Zadevajo tudi delovanje mobilnih postaj v neposrednem načinu (DM-MS) s ponavljalnikom neposrednega načina delovanja tipa 1.
OPOMBA 1: Specifikacije za skupno izvajanje ponavljalnika/prehoda neposrednega načina (DM-REP/GATE) so skupaj s specifikacijami za prehod neposrednega načina (DM-GATE) navedene v dokumentu EN 300 396-5 [5].
OPOMBA 2: Specifikacije za ponavljalnik neposrednega načina kot samostojno enoto, ki podpira dva klica na radijskem vmesniku (ponavljalnik neposrednega načina tipa 2), so navedene v dokumentu EN 300 396-7 [i.3].
Protokol za mobilno postajo neposrednega načina, ki deluje s ponavljalnikom neposrednega načina tipa 1, je naveden v točkah 5, 8, 10 in 11. Velik del tega protokola je opredeljen v obliki »delta dokumenta«, ki se nanaša na specifikacije za neposredno delovanje od mobilne postaje do mobilne postaje iz dokumentov EN 300 396-2 [2] in EN 300 396-3 [3]. V teh točkah je navedeno, kje se protokol iz dokumentov EN 300 396-2 [2] in EN 300 396-3 [3] uporablja nespremenjen in kje z navedenimi spremembami, zamenjavami ali dodatki.
Kjer sklicevanje na dokument EN 300 396-2 [2] ali EN 300 396-3 [3] ne obstaja, je treba točko obravnavati kot samostojno.
Protokol za ponavljalnik neposrednega načina je določen v točki 9 in 12.
Normativni dodatek v glavnem določa vrednosti parametrov, ki se uporabljajo v protokolu.
General Information
Overview
ETSI EN 300 396-4 V1.4.1 (2011-12) is the Slovenian identical adoption of the ETSI standard EN 300 396-4 (V1.4.1) that specifies the air interface technical requirements for a TETRA Direct Mode Operation (DMO) Type 1 repeater (DM-REP). The document defines protocol behaviour, message formats and operational rules required for repeaters and mobile stations operating in DMO with a Type 1 repeater, ensuring interoperable TETRA DMO communications.
Key topics and technical requirements
This part of the EN 300 396 series focuses on the air interface and includes detailed material on:
- Protocol overview and definitions: terminology, abbreviations and protocol architecture for DM operation with a Type 1 DM-REP.
- DM channel and frame structure: rules for DM channel arrangement, channel surveillance and constraints on frame structure when a DM-REP is present.
- Layer 2 (MAC) and Layer 3 services: service primitives (e.g., DMA-UNITDATA), mapping of logical channels at the DMV-SAP, upper/lower MAC functions and PDU formats.
- Call procedures and signalling: procedures for call setup (with and without presence check), changeover, reservation, pre-emption and termination in circuit mode calls using a DM-REP.
- Short Data Service (SDS): sending/receiving unacknowledged and acknowledged short data messages, SDS-TL in DMO and transaction handling during calls.
- Operational states and capabilities: DM-MAC state machine, DM-MS capabilities including dual-mode/dual-watch options and master/slave behaviours.
- Error protection and scrambling: PDU error detection and optional extended error protection mechanisms relevant to DM-REP operation.
Keywords naturally present: TETRA, DMO, Type 1 repeater, DM-REP, air interface, DM channel, DM-MS, MAC, SDS, PDU.
Practical applications and users
This standard is intended for professionals involved in designing, testing, deploying and certifying TETRA DMO equipment:
- Radio manufacturers and firmware engineers implementing Type 1 repeater functionality and DM air interface protocol stacks.
- Repeater and subsystem vendors integrating DM-REP features and ensuring interoperability with TETRA mobile stations (DM-MS).
- Test laboratories, certification bodies and system integrators performing conformance, interoperability and acceptance testing.
- Public safety, utilities and transport agencies procuring DMO-capable radios and repeaters who need assurance of standard-compliant behaviour.
Implementing the requirements supports reliable direct-mode communications, improved coverage using repeaters, and predictable behaviour for mission-critical TETRA DMO services.
Related standards
- ETSI EN 300 396 series (other parts cover broader DMO technical and conformance aspects)
- ETSI publications and national adoptions (SIST) provide the authoritative PDF reference and status information.
For implementation or procurement, consult the official ETSI/SIST PDF of EN 300 396-4 V1.4.1 for normative details, PDU diagrams and exact service primitive definitions.
