(Main)Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 3: Interworking at the Inter-System Interface (ISI); Sub-part 2: Additional Network Feature Individual Call (ANF-ISIIC)
- Abstract
The present document defines the Terrestrial Trunked Radio (TETRA) system 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 is the ANF-ISIIC sub-part.
ANF-ISIIC enables calls to be set-up by a user registered in one TETRA network to another user registered in another TETRA network, operating at the ISI of both SwMIs. It also supports call restoration when a user has migrated to another TETRA network during an established call. Additionally, ANF-ISIIC allows TETRA signalling information to be passed from a TETRA SwMI to another TETRA SwMI supporting the TETRA individual call procedures as defined in clauses 11 and 14 of EN 300 392-2 [1].
Like all other Additional Network Feature (ANF) specifications, those of ANF-ISIIC are produced in three stages, according to the method described in ITU-T Recommendation I.130 [11]. 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. And the partial stage 3 description of ANF-ISIIC specifies its protocol.
NOTE: According to ITU-T Recommendation I.130 [11], the stage 3 description of a bearer or tele-service addresses the network implementation aspects. Consequently, it comprises two steps: the specifications of all protocols at the various reference points involved in any of the service procedures (notably the service operation) are the first step of the stage 3 description, and the specifications of the functions of the corresponding network entities are its second step. The latter have not been provided since they can be derived from the specification of the functional entity actions in the stage 2 description. The present document applies to TETRA networks which support inter-TETRA individual calls. More specifically, it applies to their Circuit Mode Control Entities (CMCE), as defined in clause 14.2 of EN 300 392-2 [1], and to their ANF-ISIIC entities defined in the stage 2 description.

SIST EN 300 392-3-2 V1.2.1:2006 is the Slovenian adoption of ETSI EN 300 392-3-2 V1.2.1 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies the Additional Network Feature Individual Call (ANF-ISIIC) at the Inter-System Interface (ISI), including how a TETRA user in one Switching and Management Infrastructure (SwMI) sets up, maintains, restores, and clears an individual call to a user in another SwMI. The standard is written for TETRA network, SwMI, and gateway implementers who need the inter-network signalling rules for this call type.
What does SIST EN 300 392-3-2 V1.2.1:2006 specify?
SIST EN 300 392-3-2 V1.2.1:2006 specifies the TETRA V+D interworking feature ANF-ISIIC. It describes the user-visible service, the functional entities and information flows behind it, and the protocol details needed to carry the service over the ISI.
The document is organized as follows:
- Clause 1 - scope
- Clause 2 - references
- Clause 3 - definitions and abbreviations
- Clause 4 - ANF-ISIIC stage 1 specification
- Clause 5 - ANF-ISIIC stage 2 specification
- Clause 6 - ANF-ISIIC stage 3 specification
- Annexes A to C - informative material
| Annex | What it covers |
|---|---|
| A | Static description of the TETRA individual call bearer service using attributes |
| B | Definition of the ISI ROSE operation |
| C | Interactions of SS-CFU with ANF-ISIIC |
In practice, the scope is the interworking of individual calls between TETRA networks over the ISI, including call restoration after user migration and signalling transfer between SwMIs.
What are the key requirements of SIST EN 300 392-3-2 V1.2.1:2006?
SIST EN 300 392-3-2 V1.2.1:2006 defines how ANF-ISIIC behaves at call set-up, during an active call, and when a user migrates to another network. The most important requirements are in clauses 4 to 6, with additional cases and procedures in annexes and figures.
Call set-up, routing and restoration
Clause 4 describes the service from the user point of view. ANF-ISIIC sets up calls from a user registered in one TETRA network to a user registered in another network, and it also supports call restoration when a user migrates during an established call. This matters because the service must keep the call usable even when the called or calling user changes network location.
Clause 4 also allows setup modification, including a change between individual call and group call, where the invoked ANF changes accordingly. Call modification may affect the 8 kbit/s encoding of user information when the data rate changes, so implementations have to adapt the user-information encoding while keeping the ISI connection itself intact.
Clause 4 says that clearing the call on either side clears the invoked ANF-ISIIC, the ISI connection, and the other SwMI call control application. It also highlights loop avoidance, including trombone connections, which is important for keeping routing efficient and preventing the same traffic from being sent back through the network path it already used.
Stage 2 functional behavior
Clause 5 models ANF-ISIIC with functional entities (FEs) and information flows. The functional model includes originating, terminating, migration-handling, routeing, and information-provision functions, and it shows how the ANF relates to the basic call functional model. For implementers, this is the bridge between service behaviour and actual software or network functions.
Clause 5 also defines named information flows such as CALL RESTORE, CALL RESTORE PREPARE, MIGRATION, SETUP, TX-GRANTED, TX-INTERRUPT, and TX-CEASED. These flows matter because they are the exchange points that an implementation must support when a call is being established, modified, restored, or controlled for transmission.
Clause 5 includes examples for successful and unsuccessful call set-up, migration using forward switching or re-routeing, call restoration, and resource queuing and allocation. The resource case is important when the terminating side allocates radio traffic channels temporarily and the originating side has to wait or retry before the call can connect.
Stage 3 protocol rules and coding
Clause 6 turns the service into protocol requirements. Each SwMI has to meet the requirements for message segmentation/re-assembly and ROSE protocol support named in the referenced standards, and ANF-ISIIC uses ROSE Invoke APDUs carried in PSS1 facility information elements. In practice, this means TETRA-specific inter-system signalling is embedded in PSS1 messages rather than sent as a separate protocol.
Clause 6.3 defines the TETRA PDUs used on the ISI, including SETUP, PROGRESS, ALERTING, CONNECT, FACILITY, DISCONNECT, RELEASE, and resource-handling PDUs. It also defines a range of information elements used for routing, migration, call identity, party identity, priority, transmission control, and resource status. These fields are what an implementer has to encode and decode correctly for interworking to succeed.
Clause 6.5 covers signalling procedures for call establishment, maintenance, DTMF procedures, clearing, and call collisions. Clause 6.8 defines timer use, including a restoration timer for migration cases. That is the practical safeguard against a call staying in an intermediate state for too long.
Interactions with other services and gateways
Clause 4 and clause 6 both deal with interactions with other supplementary services such as SS-CFU, SS-CFB, SS-CAD, SS-BIC, SS-CW, SS-HOLD, SS-CCBS, SS-CCNR, SS-AoC, and others. This matters because an ANF-ISIIC implementation must respect forwarding, barring, dispatcher authorization, and priority behaviour at the same time as the inter-system call routing.
Clause 4.4 and clause 6.6 cover interworking with PSTN, ISDN, and PISN through gateways. The originating SwMI includes gateway and external number information in the SETUP PDU, and the gateway provides progress and connected information back to the TETRA side. This is the part of the document that supports external calls through a TETRA gateway rather than only TETRA-to-TETRA calls.
What terms does SIST EN 300 392-3-2 V1.2.1:2006 define?
SIST EN 300 392-3-2 V1.2.1:2006 uses a small set of core terms to describe the routing model and the call-control entities.
- ANF - Additional Network Feature, the staged service feature model used for TETRA interworking specifications.
- ISI - Inter-System Interface, the interface over which TETRA networks interwork with each other.
- SwMI - Switching and Management Infrastructure, the network-side control domain that routes and manages calls.
- CMCE - Circuit Mode Control Entities, the TETRA call control entities that this sub-part applies to.
- FE - Functional Entity, the stage 2 modelling unit used to describe how the service is implemented.
- home SwMI - the SwMI that owns the Individual TETRA Subscriber Identity (ITSI) through its Mobile Network Identity (MNI).
- forward switching - the routeing method that joins two connections through an intermediate SwMI to carry the call onward.
- loop connection - an ISI connection whose two ends are in the same SwMI, which the standard seeks to avoid in routing cases.
Who uses SIST EN 300 392-3-2 V1.2.1:2006?
SIST EN 300 392-3-2 V1.2.1:2006 is used by TETRA network operators, SwMI vendors, gateway designers, and integration teams responsible for inter-network call control. It is especially relevant to engineers implementing call routing, migration handling, supplementary service interactions, and PSS1/ROSE signalling across the ISI.
It also matters to test and validation teams, because the document contains the call-sequence examples, information flows, and coding rules needed to check interoperability between two SwMIs and between TETRA and external networks.
Which standards are used with SIST EN 300 392-3-2 V1.2.1:2006?
SIST EN 300 392-3-2 V1.2.1:2006 relies on several related standards and companion parts.
- ETSI EN 300 392-2 - provides the TETRA air interface and the individual-call procedures referenced throughout clause 4 and clause 6.
- ETSI EN 300 392-3-1 - gives the general ISI design and the ROSE protocol support used by ANF-ISIIC.
- ETSI EN 300 392-3-5 - covers ANF-ISIMM, which is relevant to migration and call-restoration behaviour.
- ISO/IEC 11572 - provides PSS1 message segmentation/re-assembly support and the timers used by the inter-exchange signalling.
- ISO/IEC 11574 - provides PISN basic call service description, functional capabilities, and information flows.
- ISO/IEC 11582 - provides the generic functional protocol for supplementary services and the inter-exchange signalling procedures used with facility information elements.
- ITU-T Recommendation I.460 - provides multiplexing and rate-adaptation support used when TETRA streams are carried in the described connection model.
Clause 6 also uses EN 300 172, EN 300 392-9, EN 300 392-12-4, and ETS 300 395-2 for specific fields and coding rules in the PDU and information-element definitions.
What does the SIST EN 300 392-3-2 V1.2.1:2006 document contain?
SIST EN 300 392-3-2 V1.2.1:2006 contains a staged specification of ANF-ISIIC rather than a short service summary. Clause 4 gives the stage 1 service description and includes an overall SDL in Figure 2; clause 5 gives the stage 2 functional model, example information-flow sequences, and the mapping of functional entities to physical equipment and SwMIs; clause 6 gives the stage 3 protocol rules, coding requirements, signalling procedures, and timer behaviour.
The document also contains a large set of tables for PDU contents and information-element coding, especially in clause 6.3.1 and 6.3.2. Those tables are the practical coding reference for implementers who have to build or validate signalling messages.
Annex A reformulates bearer-service attributes, Annex B defines the ISI ROSE operation, and Annex C walks through SS-CFU interaction cases. Together they provide the background needed for design, interoperability testing, and protocol implementation.
