SIST EN 300 392-10-17 V1.2.1:2003 is the Slovenian publication of the ETSI European Standard for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D), Part 10, Sub-part 17. It specifies the stage 1 description of the Include Call (IC) supplementary service for TETRA speech teleservices and speech bearer services, from the user-service point of view. For network operators and service implementers, it explains when an active call can add a second call and how the network should handle that change.

What does SIST EN 300 392-10-17 V1.2.1:2003 specify?

SIST EN 300 392-10-17 V1.2.1:2003 specifies the service description, procedures, interactions and interworking considerations for the Include Call supplementary service in TETRA. It is a stage 1 document, so it focuses on service behavior rather than detailed user interface design or lower-layer protocol detail.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions and abbreviations
• Clause 4 - Conformance
• Clause 5 - SS-IC stage 1 specification
• Annex A - Bibliography

Clause 5 covers the service description, normal and exceptional procedures, interactions with other supplementary services, interworking considerations, and an overall SDL model. Annex A gives the bibliography used with the document.

What are the key requirements of SIST EN 300 392-10-17 V1.2.1:2003?

Service behavior and applicability

SIST EN 300 392-10-17 V1.2.1:2003 defines Include Call as a service that lets a served user in an active original call make a second call and have the new party included in the original call. Clause 5.1 also limits the service to TETRA speech teleservices and speech bearer services.

In practice, this means the service is about expanding an ongoing speech call, not about data services or general call setup.

Provision, activation and user control

Clause 5.2.1 says SS-IC may be provided either by prior arrangement with the service provider or generally to all users. The service may also be withdrawn by user request or for administrative reasons.

Clause 5.2.2 states that SS-IC is permanently activated when provided and deactivated when withdrawn. Definition, registration and interrogation are not applicable, while cancellation is done with an appropriate basic call control procedure. For operators, this keeps service management simple: the key decisions are provision and withdrawal, not user-side configuration.

Invocation and resulting call handling

Clause 5.2.2.2 says the served User A invokes SS-IC while in an active original call with User B. In an individual call, either party may invoke it; in a multipoint call, only the call owner may do so. The SwMI includes User C only when User C responds positively, or immediately when User C is a group.

The service shall not interrupt the original call. The resulting call is always treated as a multipoint call, and the document uses Table 1 to show how the result depends on the original call type and the SS-IC invocation. In practice, implementers need to preserve the original conversation while adding the new participant in a controlled way.

Exceptional cases and rejection handling

Clause 5.2.3 requires the network to reject a request if User A is not permitted to use SS-IC. The rejection shall indicate denial in the disconnect message, but the original call shall continue normally. The document distinguishes short-term denial, where a later request might succeed, from long-term denial, where later requests will also be rejected.

That distinction matters for user experience and network behavior: a temporary resource or state issue is handled differently from a permanent entitlement or interworking limitation.

Interactions with other services

Clause 5.3 states that SS-IC generally does not interact with many other supplementary services, including calling line identification presentation, connected line identification presentation, call report, talking party identification, list search call, short number addressing, access priority, priority call, discreet listening, ambience listening, dynamic group number assignment and call retention. It also gives specific interaction rules for call forwarding, call waiting, call hold, barring of outgoing calls, barring of incoming calls, call completion to busy subscriber and call completion on no reply.

For example, barring rules take precedence if they conflict with SS-IC, and call forwarding can apply to the second call. This matters because the network must resolve service conflicts consistently when Include Call is used with other features.

What terms does SIST EN 300 392-10-17 V1.2.1:2003 define?

• Include Call (IC) - A supplementary service that adds a second call into an ongoing original call.
• served User A - The user who invokes SS-IC.
• User B - The other party in the original call.
• User C - The other party in the second call that is to be included.
• call owner - The user who controls a multipoint call and can clear it down.
• resulting call - The call formed after the second call has been included in the original call.
• SwMI - Switching and Management Infrastructure, meaning the TETRA network equipment excluding subscriber terminals.
• teleservice - A telecommunication service that includes terminal equipment functions for communication between users according to agreed protocols.

Who uses SIST EN 300 392-10-17 V1.2.1:2003?

SIST EN 300 392-10-17 V1.2.1:2003 is used by TETRA network operators, service providers, system integrators and equipment implementers who need to support Include Call. It is also useful for engineers and testers checking how an active call should behave when another party is added, especially in speech teleservices and speech bearer services.

What changed in SIST EN 300 392-10-17 V1.2.1:2003 from the previous edition?

The document history shows an earlier publication as ETS 300 392-10-17 V1.2.0 and a later publication as V1.2.1. It also records publication through the ETSI one-step approval procedure.

Which standards are used with SIST EN 300 392-10-17 V1.2.1:2003?

• ITU-T Recommendation Z.100 - Provides the Specification and Description Language (SDL) used for the dynamic service model in clause 5.5.
• EN 300 392-9 - Gives the general requirements for TETRA supplementary services.
• EN 300 392-11 - Covers supplementary services stage 2.
• EN 300 392-12 - Covers supplementary services stage 3.
• ETS 300 392-13 - Gives the SDL model of the Air Interface (AI).
• ETS 300 392-14 - Provides Protocol Implementation Conformance Statement (PICS) proformas.
• TS 100392-15 - Covers TETRA frequency bands, duplex spacings and channel numbering.
• TS 100392-16 - Covers network performance metrics.
• TS 100392-17 - Covers TETRA V+D and DMO Release 1.1 specifications.

What does the SIST EN 300 392-10-17 V1.2.1:2003 document contain?

The document contains a compact stage 1 service specification, not an implementation protocol. Clause 5 gives the service definition, operating procedures, service interactions and interworking rules, while clause 3 defines the key service roles and abbreviations.

It also includes Table 1, which maps original-call and SS-IC combinations to the type of resulting call. Figures 1 and 2 provide an overall SDL view of the network behavior for Include Call, which is useful when designing or reviewing service logic. Annex A gives reference material used by the standard.
