SIST EN 300 392-10-14 V1.2.1:2003 is the Slovenian adoption of ETSI EN 300 392-10-14 V1.2.1 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It defines the stage 1 description of Supplementary Service Late Entry (SS-LE), so it explains what the service does, how the network presents it, and how users may join an already running multipoint speech or data call. The standard is aimed at TETRA service providers, network operators, and equipment implementers who need the service model and its interactions with other supplementary services.

What does SIST EN 300 392-10-14 V1.2.1:2003 specify?

SIST EN 300 392-10-14 V1.2.1:2003 specifies the stage 1 service description of SS-LE for TETRA. Stage 1 is the user-level view of the service, so this document focuses on behavior and procedures rather than the detailed human interface.

The scope says SS-LE lets radio users be informed of, and if relevant join, an existing multipoint call. It also states that charging principles are outside the scope.

The document is organized into:

• Clause 1: Scope
• Clause 2: References
• Clause 3: Definitions and abbreviations
• Clause 4: SS-LE stage 1 specification, including description, procedures, interactions, inter-working considerations, and SDL
• Annex A: Informative bibliography

What are the key requirements of SIST EN 300 392-10-14 V1.2.1:2003?

Clause 4.1 ties SS-LE to a multipoint speech call and to the called group identity. In practice, the service is group-based, not a one-to-one call feature.

Clause 4.1.2 extends SS-LE to all TETRA multipoint speech and data circuit mode services. That means the same service logic applies to both voice and data group communications.

Clause 4.2.1 and 4.2.2 define how the service is provided, activated, and managed. SS-LE may be provisioned either against a specific Group TETRA Subscriber Identity (GTSI) or to an authorized user, and the authorized user supplies the group identity, LE definition or removal, LE use over ISI, call behaviour, basic service type, and repetition rate. In practice, operators need a clear configuration record for each group.

Clause 4.2.2.2 says the network invokes SS-LE after call setup is complete when the service is active for the called group identity. The network sends indications for the duration of the call, and the user response depends on the message type: LE broadcast and LE acknowledgement allow direct joining, while LE paging requires a radio resource request first.

Clause 4.2.3 gives the failure handling for definition and interrogation. The standard names typical rejection causes such as invalid or unknown GTSI, insufficient information, unsupported basic service, lack of authorization, or invalid parameters. That matters because provisioning and operations systems need meaningful error feedback.

Clause 4.3 lists interactions with other supplementary services. Many services are stated to have no interaction with SS-LE, while forwarding cases, area selection, priority call, and inter-system behavior have specific handling notes. In practice, this section is the main check-list for interoperability testing.

Clause 4.4 says SS-LE shall be supported over Inter-System Interface (ISI) when both connected Switching and Management Infrastructures (SwMI) support it. Clause 4.5 adds an SDL model of the network behavior.

What terms does SIST EN 300 392-10-14 V1.2.1:2003 define?

• Group TETRA Subscriber Identity (GTSI) is the group identity used for provisioning, definition, registration, and interrogation of SS-LE.
• Switching and Management Infrastructure (SwMI) is the network side that sends SS-LE indications and controls service behavior.
• Multipoint call is a point-to-multipoint teleservice or bearer service, such as a group call, acknowledged group call, or broadcast call.
• Late entry broadcast is the indication that tells members they can join directly because a channel is already allocated in the cell.
• Late entry paging is the indication that tells members they must first request a communication channel if they want to join.
• Late entry acknowledgement is the indication sent by the SwMI to tell a member to inform the SwMI of entry into the call.
• Supplementary Service (SS) is a service that modifies or supplements a bearer service or teleservice and is not offered as a standalone service.

Who uses SIST EN 300 392-10-14 V1.2.1:2003?

SIST EN 300 392-10-14 V1.2.1:2003 is used by TETRA service providers and network operators when they provision SS-LE for group identities. It is also used by equipment vendors, mobile station developers, system integrators, and test teams.

Typical tasks include:

• defining and removing SS-LE settings
• implementing LE broadcast and paging behavior
• handling join requests during an ongoing multipoint call
• checking interactions with forwarding and priority services
• verifying ISI interworking between connected SwMIs

What changed in SIST EN 300 392-10-14 V1.2.1:2003 from the previous edition?

The scope says this document is a revision of stage 1 after PE resolution of stages 2 and 3. The history shows that it replaces ETS 300 392-10-14 V1.2.0 and was published as V1.2.1.

Which standards are used with SIST EN 300 392-10-14 V1.2.1:2003?

• ITU-T Recommendation Z.100 - provides the Specification and Description Language (SDL) used for the behavior model in Clause 4.5.
• EN 300 392-9 - gives the general requirements for TETRA supplementary services.
• EN 300 392-11 and EN 300 392-12 - provide the stage 2 and stage 3 specifications that sit alongside this stage 1 service description.
• EN 300 392-13 - is the SDL model of the Air Interface (AI), named in the series context.
• EN 300 392-14 - is the PICS proforma specification named in the series context.

What does the SIST EN 300 392-10-14 V1.2.1:2003 document contain?

Clause 4.2 contains the practical service procedures for provision, withdrawal, activation, deactivation, definition, registration, interrogation, and invocation. Clause 4.3 lists the service interactions with other TETRA supplementary services, which is the part readers usually use for compatibility checks.

Clause 4.5 includes Figure 1, an SDL view of SS-LE network behavior with states such as IDLE and ACTIVE and with send, broadcast, and paging transitions. Annex A gives a short informative bibliography with ITU-T Recommendation I.130.
