Prizemni snopovni radio (TETRA) - Tehnične zahteve za neposredni način delovanja (DMO) - 3. del: Protokol radijskega vmesnika (AI) od mobilne postaje do mobilne postaje (MS-MS)
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 tega določa varnostne vidike neposrednega načina delovanja prizemnega snopovnega radia,
in poleg osnovnih nosilnih in telekomunikacijskih storitev tudi podprte storitve.
Ta dokument se uporablja za radijski vmesnik neposrednega načina delovanja prizemnega snopovnega radia od mobilne postaje do mobilne postaje in vsebuje specifikacije za plast podatkovne povezave (DLL) in omrežno plast v skladu z modelom ISO.
Uvaja storitve, sporočila in protokole za glasovne in vodovne podatkovne klice ter kratek prenos podatkov, pri čemer začenja z zgornjimi plastmi:
• določa in opredeljuje protokol, ki ga osebek iz plasti 3 uporablja za komunikacijo prek radijskega vmesnika;
• določa in opredeljuje storitve ter protokol, ki jih uporablja plast podatkovne povezave.
Normativni dodatki v glavnem določajo vrednosti parametrov, ki se uporabljajo v protokolu.
General Information
Overview
ETSI EN 300 396-3 V1.4.1 (2011-12) specifies the Mobile Station to Mobile Station (MS‑MS) Air Interface (AI) protocol for Terrestrial Trunked Radio (TETRA) Direct Mode Operation (DMO). This European (ETSI-origin) standard - adopted by SIST under reference REN/TETRA-08193 - defines protocol behaviour, message primitives and state machines that enable direct, radio-to-radio communication without network infrastructure.
Key topics and technical requirements
The standard provides detailed protocol-level requirements across Layer 2 and Layer 3 for DMO MS‑MS communication. Key technical topics include:
- Protocol overview and layering - structure and responsibilities of the DM air interface protocol stack (Layer 2 and Layer 3).
- DM channel and frame constraints - rules governing direct mode channels and frame structure.
- Call handling procedures - comprehensive flows for call setup, changeover, termination and pre-emption:
- Circuit mode calls (with and without presence check)
- Master/slave behaviour during occupation and reservation
- Use of DM‑OCCUPIED PDU and TPNI (Transmitting Party Number Identification)
- Short Data Service (SDS) - sending/receiving unacknowledged and acknowledged short data, including SDS-TL service details.
- Primitives and service interfaces - Layer 3 primitives (e.g., DMCC-SETUP, DMCC-REPORT, DMCC-SDS UNITDATA) and Layer 2 primitives (DMA-UNITDATA, DMA-REPORT) with parameter descriptions.
- State machines and procedures - explicit DMCC protocol states (IDLE, CALL SETUP, CALL ACTIVE TX/RX, PRE-EMPTION, ACK'D/UNACK'D short data) and step‑by‑step call/data procedures.
- Additional addressing and error protection - addressing mechanisms and optional extended error protection for SDS.
(These topics and message names are taken from the standard’s table of contents and normative sections.)
Practical applications
This standard is essential for ensuring interoperable, reliable direct-mode communication in scenarios where infrastructure is unavailable or undesirable:
- Public safety and emergency services requiring device-to-device voice and data in off-network conditions.
- Critical-communications device manufacturers implementing DMO MS‑MS protocol stacks.
- System integrators and test labs validating DMO compliance, call handling, SDS transactions and pre-emption behaviour.
- Procurement and regulatory bodies specifying conformity for TETRA equipment used in mission-critical deployments.
Who should use this standard
- Radio hardware and firmware engineers implementing TETRA DMO.
- Protocol and systems engineers designing TETRA terminals.
- Test engineers and certification bodies conducting interoperability and conformance testing.
- Emergency communications planners and procurement teams setting technical requirements.
