SIST EN 300 392-3-3 V1.2.1:2006 is the Slovenian adoption of ETSI EN 300 392-3-3 Version 1.2.1 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies the Additional Network Feature Group Call (ANF-ISIGC) at the Inter-System Interface (ISI), so TETRA operators and equipment suppliers can define how group calls are set up, maintained, restored and cleared between Switching and Management Infrastructure (SwMI) networks and through gateways. The document is aimed at people who design, integrate, test or procure TETRA network interworking.

What does SIST EN 300 392-3-3 V1.2.1:2006 specify?

SIST EN 300 392-3-3 V1.2.1:2006 specifies the ANF-ISIGC part of TETRA V+D interworking over the ISI. The scope covers group-call interworking between TETRA networks, interworking with other networks via gateways, and the supplementary services that apply to the basic TETRA tele- or bearer services.

The standard is organized into three service-description stages plus annexes. Clause 4 gives the stage 1 service view, clause 5 gives the stage 2 functional model and information flows, and clause 6 gives the stage 3 signalling, coding and state definitions.

Annex	What it covers
Annex A	Normative Specification and Description Language (SDL) representation of the procedures
Annex B	Normative stage 2 description of the interactions between ANF-ISIGC and SS-CAD when invoked for the called group
Annex E	Example call setup, maintenance and termination scenarios

What are the key requirements of SIST EN 300 392-3-3 V1.2.1:2006?

The core requirement is that ANF-ISIGC provides inter-system TETRA group-call handling across the ISI. In practice, the document defines which group-call service types are supported, how calls are routed and controlled, how transmission rights are managed, and how roaming and restoration are handled when users move between SwMIs.

Supported group-call services

Clause 4 states that ANF-ISIGC covers TETRA Group Call clear speech, acknowledged and unacknowledged, Group Call End-to-End Encrypted speech, Group Call Circuit Mode one-slot data, and multi-slot data at N × 2.4 kbit/s, N × 4.8 kbit/s or N × 7.2 kbit/s for N = 2, 3 or 4, including encrypted versions. For a reader, this means the implementation has to support both speech and data group calls, and it has to preserve the service type across network boundaries.

Call establishment and routing

Clause 4.2.2.3 describes call establishment from the originating SwMI through the group home or linking controlling SwMI. The originating SwMI checks that the request is allowed and that a routing path exists, and the controlling SwMI then evaluates the group profile, routing, and available resources. This matters because the network may have to forward, re-route, accept, delay, or reject a group call depending on group membership, migration, and resource availability.

Complete, partial, and delayed set-up

The stage 1 procedures allow the controlling SwMI to accept a call completely, accept it partially, delay it, or release it. The text also describes implementation-specific acceptance policies, such as accepting when at least one member can be connected, when all critical users can be connected, or only when all members can be connected. For operators, this means service policy and resource policy are part of the design choice, not just signalling.

Transmission control during an active call

Clause 4.2.2.3.7 keeps ANF-ISIGC active for the duration of the call and uses it to manage transmission rights. The document defines transmission cease, transmission request, transmission delay, and transmission interrupt behaviour, and it explains queueing, temporary resource allocation, and pre-emption. In practice, the controlling SwMI decides who may talk, when waiting requests are queued, and how a higher-priority request can interrupt an ongoing transmission.

Roaming, restoration, and continuation

The standard requires group-call restoration when an active user migrates to a new SwMI. If the call already exists at the new participating SwMI, the restoration can be confirmed without repeating the full setup sequence; if not, the call is extended to the new SwMI. This is important for mobility, because users can move while staying in the same group call.

Termination and exceptional handling

Only the controlling SwMI controls termination of the whole group call. A participating SwMI may request disconnect, and the controlling SwMI can choose to release the whole call or only that SwMI, for example if resources are pre-empted or a local call timer expires. Clause 4.2.3 also lists exceptional cases such as missing polling responses, unavailable critical subscribers, and other failure conditions.

Protocol model, coding and timers

Clause 5 breaks the service into functional entities FE1 to FE5, with information flows between originating, controlling and participating SwMIs plus database entities for ITSI and GTSI. Clause 6 then turns that model into signalling procedures and PDU coding. The signalling is carried as ROSE Invoke APDUs using the tetraIsiMessage operation, and the document also defines timer use, including a 30 s value for T1 when group call setup is delayed.

The standard also defines how ANF-ISIGC interacts with other TETRA supplementary services, including SS-CFU, SS-CAD, SS-AS, SS-PC, SS-PPC, SS-IC and SS-CRT, and it describes gateway interworking with PSTN, ISDN and PISN. For implementers, that means group-call signalling must coexist with forwarding, priority, dispatcher authorization, retention and external network calls without breaking call control.

What terms does SIST EN 300 392-3-3 V1.2.1:2006 define?

• Controlling SwMI - the SwMI that sets up and maintains a call between two or more SwMIs.
• Group home - the home of the GTSI, meaning the SwMI where the network code (MNC) matches the group identity.
• Individual home - the home of the MS’s ITSI, meaning the SwMI where the MNC matches the individual subscriber.
• Linking controlling SwMI - the SwMI that controls linking of one of its own groups to one or more groups from other SwMIs.
• Transit SwMI - a SwMI through which the call passes but which is neither originating, controlling nor participating in the call.
• Visited SwMI - a TETRA network whose MNI is not equal to the user’s MNI.
• GTSI - Group TETRA Subscriber Identity, used to identify the called group.
• ITSI - Individual TETRA Subscriber Identity, used to identify the calling or restoring subscriber.

Who uses SIST EN 300 392-3-3 V1.2.1:2006?

The standard is used by TETRA network operators, SwMI vendors, gateway designers, and signalling engineers who need inter-system group calling to work across networks. It is also used by test and conformance teams that verify call setup, transmission control, roaming restoration, and disconnection behaviour. Buyers and quality managers use it to check that a proposed TETRA platform supports the required ISI group-call functions and the relevant interactions with other services.

What changed in SIST EN 300 392-3-3 V1.2.1:2006 from the previous edition?

What does the SIST EN 300 392-3-3 V1.2.1:2006 document contain?

The standard contains a stage 1 service description, a stage 2 functional model with message sequence charts, and a stage 3 signalling specification with PDU definitions and state machines. It also includes normative SDL in Annex A, normative SS-CAD interaction material in Annex B, and example scenarios in Annex E.

Clause 6 contains the main coding tables for ANF-ISIGC information elements, such as call resource time-out, group identifiers, resource indicators, reject causes, security level, set-up type, speech-service selection, and transmission control indicators. The document also includes detailed signalling procedures for setup, acknowledgement, maintenance, call restoration, disconnection, and mapping between PSS1 messages and ISI PDUs.

For testing and implementation work, the most useful parts are the information flow diagrams, the FEA descriptions, the state definitions, and the annexed SDL sheets. These show how an implementation should move between IDLE, WAIT CONNECT, ACTIVE, DELAY GROUP CALL, CALL RELEASE and related states while exchanging the defined ISI messages.
