SIST EN 300 392-3-4 V1.2.1:2006, published by SIST, is the Slovenian version of ETSI EN 300 392-3-4 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) interworking at the Inter-System Interface (ISI). It specifies the Additional Network Feature Short Data Service (ANF-ISISDS), including how short data and status messages are carried between TETRA Switching and Maintenance Infrastructure (SwMI) entities, for engineers and operators who need the service model, message flow, and coding.

What does SIST EN 300 392-3-4 V1.2.1:2006 specify?

SIST EN 300 392-3-4 V1.2.1:2006 specifies the ISI Short Data service for TETRA V+D between SwMIs. The document is focused on how SDS and status messages are transferred from one network to another, including stage 1, stage 2, and a partial stage 3 description.

The standard is organized into the usual ETSI structure: scope, references, definitions and abbreviations, then the three ANF-ISISD specification stages, followed by annexes.

Annex	What it covers
Annex A	Interaction with other TETRA supplementary services and ANFs
Annex B	Change Requests

The scope also makes one practical boundary clear: ANF-ISISD is invoked only for cross-SwMI cases that fit the described scenarios, and scenario (3) is not used to invoke the service.

What are the key requirements of SIST EN 300 392-3-4 V1.2.1:2006?

Clause 4 defines ANF-ISISD as transparent transport of SDS across the ISI between two SwMIs. In practice, the originating SwMI forwards the message to the peer ANF-ISISD entity, so the application sees a network-to-network transfer rather than a new message format.

Service operation and invocation

Clause 4.2 says there is one invocation per SDS transfer, so each message is handled independently. Group-addressed SDS is sent first to the group-controlling SwMI for onward distribution, which matters because network routing and group delivery are not the same thing.

Clause 4.4.2.2 limits the service to the scenarios described in the document. The originating SwMI becomes the controlling SwMI in some cases, while the destination home SwMI becomes the controlling SwMI in another case; scenario (3) does not invoke ANF-ISISD. That distinction matters when deciding which SwMI manages the transfer and where the SDS profile is handled.

Availability, security, and failure handling

Clause 4.4 states that ANF-ISISD is always available and always activated. Registration and interrogation are not applicable, which simplifies service management for implementers.

Clause 4.3 requires the participating SwMIs to exchange the security class used at the air interface. The destination SwMI discards any message from a source SwMI operating at a numerically higher security class. In practice, this is a network-side admission rule that affects whether a message is accepted for transfer.

Clause 4.4.3 lists service rejection conditions such as no subscription to inter-system short data service, ISI out of order, or a remote SwMI that does not support short data service. During service operation, the request may also fail if the user is not reachable or not known.

Primitives and parameters

Clause 4.5 translates the service into ANFISISD-STATUS and ANFISISD-UNITDATA primitives. The important parameters are the called and calling identities, the selected area number, hop count, security level, status number, short data type identifier, and the user defined data fields. This is the part an implementer uses to map network information into the service primitive.

A few parameter rules are especially relevant in practice:

• The external subscriber number can be up to 24 digits.
• The status number reserves values 1 to 32 767 and leaves 32 768 to 65 535 for TETRA network-specific definition.
• The short data type identifier selects user defined data-1, -2, -3, or -4.
• User defined data-4 can be up to 2 047 bits.
• The hop count shows how many times the message is sent over an ISI connection.

Stage 2 and stage 3 behavior

Clause 5 defines four functional entities: FE1, FE2, FE3, and FE4. FE2, the Originating ISI Short Data transfer functional entity, encodes the tetraIsiMessage and increments the hop count on every transmission. That matters because the hop count can help detect routing problems.

Clause 5.2 says the transfer is connectionless and carried in a ROSE Invoke APDU. Clause 6 then fixes the protocol details: the ISISD-UNITDATA PDU is transported as a call unrelated ROSE APDU, and the source and destination entities are set to anfIsisd.

Clause 6 also defines the PDU contents and the coding of the information elements. The document specifies the PDU type, security level, called and calling party identities, ISISD subtype, pre-coded status, selected area number, and the user defined data fields. For implementers, this is the section that drives message encoding and interoperability testing.

What terms does SIST EN 300 392-3-4 V1.2.1:2006 define?

• ANF-ISISD - The additional network feature for ISI short data service, used to transfer short data and status messages between SwMIs.
• SwMI - The TETRA Switching and Maintenance Infrastructure that controls service handling and interworking.
• ISI - The Inter-System Interface used for interworking between TETRA networks.
• SDS - Short data service, the message service carried across the ISI in this part.
• Hop count - The field that records how many times the message is sent over an ISI connection.
• Selected area number - The area-selection information element carried from the source primitive into the transferred PDU.
• ROSE - The protocol operation used here to carry the ISISD-UNITDATA PDU.

Who uses SIST EN 300 392-3-4 V1.2.1:2006?

SIST EN 300 392-3-4 V1.2.1:2006 is used by TETRA network operators, SwMI designers, protocol implementers, and interoperability testers. It is also relevant to equipment suppliers and integration teams that need short data and status messages to pass correctly between networks over the ISI.

In practice, these users rely on it when they configure addressing, security class handling, PDU encoding, and inter-network transfer behavior.

What changed in SIST EN 300 392-3-4 V1.2.1:2006 from the previous edition?

Annex B states that this version includes Change Request 001 from V1.1.1. The change request updates clauses 4.5, 4.5.1, 6, 6.1, 6.2, 6.3, and 6.4, and introduces new ANF-ISISD-UNITDATA PDU contents and information elements.

1 Scope
The present document defines the Terrestrial Trunked Radio system (TETRA) supporting Voice plus Data (V+D). It
specifies:
- general design aspects (e.g. reference points, numbering and addressing, or protocol architecture);
- the system bearer and mobility management services, and the corresponding air interface protocols;
- the interworking between TETRA networks;
- the interworking of TETRA networks with other networks, via gateways;
- the peripheral equipment interface on the mobile station;
- the Line Station (LS) interface with TETRA networks;
- the security protocols and mechanisms applicable to TETRA networks and to TETRA terminal equipment;
- the supplementary services applicable to the basic TETRA tele- or bearer services.
The TETRA V+D interworking - basic operation part defines the interworking between TETRA networks over the
corresponding interface: the Inter-System Interface (ISI). It comprises the following subparts:
- ISI general design;
- Additional Network Feature - ISI Individual Call (ANF-ISIIC);
- Additional Network Feature - ISI Group Call (ANF-ISIGC);
- Additional Network Feature - ISI Short Data service (ANF-ISISD);
- Additional Network Feature - ISI Mobility Management (ANF-ISIMM);
- 8 kbit/s encoding of user information at the ISI.
The present document specifies the Additional Network Function (ANF) - Inter-System Interface (ISI) Short Data
service (ANF-ISISD) which is part of the Interworking Basic Operation of the Terrestrial Trunked Radio system
(TETRA) supporting Voice and Data (V+D). Specifically the present document details the stage 1, 2 and 3 aspects of
the ANF-ISISD as seen from the TETRA Switching and Maintenance Infrastructure (SwMI) point of view at the Inter
System Interface (ISI). This service comprises of:
- TETRA user defined short message transmission over the ISI to individual and group addresses;
- TETRA pre-defined short message transmission over the ISI to individual and group addresses.
ANF-ISISD enables short data and status messages to be set-up and transferred between a user registered in one
TETRA network to another user registered in another TETRA network, operating at the ISI of both SwMIs.
Like all other Additional Network Feature (ANF) specifications, those of ANF-ISISD are produced in three stages,
according to the method described in ITU-T Recommendation I.130 [4]. The present document contains the stage 1 and
2 descriptions of ANF-ISIIC, and its partial stage 3 description. The stage 1 description specifies the ANF as seen by its
users, which are essentially the individual call control entities in both TETRA networks. The stage 2 description
identifies the functional entities involved in the ANF and the information flows between them. The partial stage 3
description of ANF-ISISD specifies its protocol.
