SIST EN 300 392-3-2 V1.3.1:2007

• 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 V1.3.1:2007 is the Slovenian standard identical to ETSI EN 300 392-3-2 V1.3.1. It specifies Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) interworking at the Inter-System Interface (ISI) for the Additional Network Feature Individual Call (ANF-ISIIC).

ANF-ISIIC is the TETRA part that lets an individual call be set up between users registered in different TETRA networks, and restored if a user migrates to another network during the call. It is written for TETRA networks and their Circuit Mode Control Entities (CMCE) and ANF-ISIIC entities.

What does SIST EN 300 392-3-2 V1.3.1:2007 specify?

SIST EN 300 392-3-2 V1.3.1:2007 specifies the ISI behavior for individual calls across TETRA SwMIs, including call establishment, migration handling, call restoration, and the signalling information that must be passed between networks.

The document is organized into the scope, references, definitions and abbreviations, then three stage descriptions of ANF-ISIIC, followed by annexes.

Annex	What it covers
Annex A	Static description of the TETRA individual call bearer service using attributes
Annex B	Definition of the ISI ROSE operation
Annex C	Interactions of SS-CFU with ANF-ISIIC
Annex D	Change Requests

What are the key requirements of SIST EN 300 392-3-2 V1.3.1:2007?

Stage 1 - service behavior and procedures

Clause 4 gives the user-visible behavior of ANF-ISIIC: provisioning, activation, invocation, call routing, time-out handling, transmission control, setup modification, call modification, call restoration after migration, and call clearing. It also covers interactions with many supplementary services and other ANFs. In practice, this is the service logic that implementers must support before they define messages and internal functions.

Stage 2 - functional model

Clause 5 defines the functional entities FE1 to FE8 and the relationships between them. These include the originating call control, route determining, migration handling, migrated called user routing, and terminating call control functions. In practice, this tells vendors how the call is split between network functions and where interworking decisions are made.

Stage 3 - operational and coding behavior

Clause 6 defines the operational requirements on the originating SwMI, terminating SwMI, called SwMI, routeing SwMI, and gateways towards PSTN/ISDN/PISN. It then specifies the PSS1 messages and TETRA PDUs used on the ISI, including setup, redirect, restore, release, and transmission control signalling. For an implementer, this is the interoperability layer: the actual messages and information elements exchanged between networks.

Migration and call restoration

ANF-ISIIC supports restoring an established call after the calling or connected user moves to another SwMI. Clause 6.3.1.14 and clause 6.5.2.3 describe restore-preparation, restore, and path handling, including cases meant to avoid trombone or loop connections. This matters because the call should survive mobility without creating inefficient or unstable routing.

Routeing choice and supplementary service interaction

The signalling includes routeing method choice and response, and the document defines how ANF-ISIIC interacts with services such as SS-CLIR, SS-CF, SS-CAD, SS-PC, SS-PPC, SS-CRT, SS-CW, SS-HOLD, SS-CCBS, SS-CCNR, SS-BIC and SS-AoC. In practice, a network must preserve the right supplementary-service behavior while still completing or rerouting the call.

Information element coding

Clause 6.3.2 defines the coding of the information elements carried in the ISI PDUs, including call status, security level, controlling SwMI, call diversion indicators, migration indicators, and number fields for external subscriber numbers and SwMI identifiers. This is what makes different vendors’ SwMIs understand the same signalling content in the same way.

What terms does SIST EN 300 392-3-2 V1.3.1:2007 define?

• ANF-ISIIC (Additional Network Feature - Inter System Interface Individual Call) - the inter-network feature for individual calls across TETRA SwMIs.
• ISI (Inter-System Interface) - the interface used for interworking between TETRA networks.
• SwMI (Switching and Management Infrastructure) - the TETRA network entity that controls switching, mobility, and call handling.
• CMCE (Circuit Mode Control Entities) - the call control entities this standard explicitly applies to.
• PSS1 - the basic call signalling protocol used for ISI call control messages.
• ROSE (Remote Operations Service Element) - the operation handling used to carry ANF-ISIIC messages in PSS1 facility information elements.
• PISN (Private Integrated Services Network) - the network model used for some of the call-control interactions and gateway behavior.
• FE (Functional Entity) - a named function in the stage 2 model, used to split call handling into interoperable roles.

Who uses SIST EN 300 392-3-2 V1.3.1:2007?

SIST EN 300 392-3-2 V1.3.1:2007 is used by TETRA network designers, SwMI and gateway vendors, and integrators who need inter-network individual calling to work between systems. It is also used by test and conformance teams checking call setup, migration, restoration, signalling coding, and supplementary-service interactions.
