SIST EN 300 392-11-18 V1.1.1:2003 is the Slovenian adoption of the ETSI TETRA standard for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D), Part 11-18, on the supplementary service Barring of Outgoing Calls (BOC). It specifies the stage 2 functional behaviour of SS-BOC for the Switching and Management Infrastructure (SwMI), Mobile Station (MS) and Line Station (LS), including how the service is defined, interrogated, applied and carried between TETRA systems. It is aimed at TETRA operators, equipment suppliers and implementers who need to control outgoing basic or packet data services.

What does SIST EN 300 392-11-18 V1.1.1:2003 specify?

SIST EN 300 392-11-18 V1.1.1:2003 specifies the stage 2 description of SS-BOC in TETRA V+D. The standard explains the service from the point of view of network functions and information exchange, not user interface details.

The document is organized into these main parts:

• Clause 1 sets the scope and states that MMI and charging principles are outside scope.
• Clause 2 lists the normative references used with the standard.
• Clause 3 gives definitions and abbreviations.
• Clause 4 gives the stage 2 specification, including the functional model, information flows, sequences, functional entity actions, allocation to physical equipment, and inter-working considerations.

Clause 4 is the technical core. It describes how the SwMI, MS and LS handle outgoing call barring and how the service behaves when a subscriber is in the home system or in a visited system, including over the Inter-System Interface (ISI).

What are the key requirements of SIST EN 300 392-11-18 V1.1.1:2003?

SIST EN 300 392-11-18 V1.1.1:2003 defines who may set SS-BOC restrictions, what those restrictions can cover, how they are signalled, and when outgoing services are barred. In practice, the standard gives implementers the rules for saving a barring definition, checking it during call setup, and informing the affected user when required.

Service definition and who may use it

Clause 4.3.1 states that an authorized user may define outgoing call barring on behalf of an affected user. The definition is only allowed for subscriber identities whose home system is the same as the authorized user’s home system.

The definition can apply to one subscriber identity, a range of identities, or a list of identities. The restrictions may cover:

• all outgoing services outside a closed user group,
• selected outgoing service types, such as basic or packet data services,
• specific destination addresses, with optional exceptions.

This matters because the network must be able to apply fine-grained barring rules, not only an all-or-nothing block.

Functional entities and their roles

Clause 4.1 describes the functional model with FE1 to FE5, plus CC and CCA. FE1 is the affected user’s function, FE2 is the SS-BOC function in the SwMI, FE3 is the authorized user’s function, FE4 carries SS-BOC information over the ISI, and FE5 represents the called party.

This model matters in practice because it shows where each task belongs. Vendors can map the service to MS, LS and SwMI equipment using the allocation in clause 4.6, and they can separate service control from basic call control.

Definition, acknowledgement and user notification

Clause 4.3.1 defines the message set for service definition: DEFINE, DEFINE-ACK, INFORM-USER and INFORM-USER-ACK. The standard allows the authorized user to request that the affected user be informed, and optionally asked to acknowledge receipt.

This is important operationally because a network may need to record not only that the barring definition was accepted, but also whether the affected user was told about it. Clause 4.3.1 also makes clear that the definition result does not by itself prove that the user notification succeeded.

Interrogation of saved SS-BOC definitions

Clause 4.3.2 lets the authorized user, and also the affected user, interrogate the SS-BOC definitions saved in the SwMI. The response shows whether SS-BOC is defined and returns the active restriction data when applicable.

The standard allows the home system to answer directly, and a visited system to answer if it already has the definition. If the visited system cannot answer, it forwards the request to the home system. In practice, this supports roaming subscribers and keeps the service visible across TETRA systems.

Operation when an outgoing service is requested

Clause 4.3.3 states that SS-BOC is applied when FE2 bars an outgoing service request from the affected user. The service is barred when the request matches the defined restrictions, including outside-closed-user-group calls, barred destination addresses, or barred service types.

The standard also states that call diversion does not override SS-BOC. It notes that call authorized by dispatcher may be used to allow a barred basic service to proceed, which matters for controlled exceptions in operational networks.

Inter-working over the ISI and physical allocation

Clause 4.7 says SS-BOC may extend across several TETRA networks. The system shall be able to deliver and receive SS-BOC definition and interrogation information over the ISI, bar services based on definitions received over the ISI, and signal barring between home and visited systems.

Clause 4.6 allocates FE1, FE3 and FE5 to LS and MS, while FE2 and FE4 are in the SwMI. This helps designers decide where the service logic and transport logic must be implemented.

What terms does SIST EN 300 392-11-18 V1.1.1:2003 define?

• affected user - The user whose outgoing calls are barred by SS-BOC.
• authorized user - The user allowed to set SS-BOC restrictions for an affected user.
• Functional Entity (FE) - A functional role that performs SS-BOC tasks in the MS, LS or SwMI.
• home system - The TETRA network that matches the user’s Mobile Network Identity (MNI) and stores the SS-BOC definition.
• visited system - A TETRA network that does not match the user’s MNI and may need to work with the home system over the ISI.
• Inter-System Interface (ISI) - The interface between two TETRA networks used to interwork services.
• Switching and Management Infrastructure (SwMI) - The TETRA network equipment that provides the V+D network function, excluding subscriber terminals.
• SS-BOC - Supplementary Service Barring of Outgoing Calls, the service that blocks defined outgoing services.

Who uses SIST EN 300 392-11-18 V1.1.1:2003?

SIST EN 300 392-11-18 V1.1.1:2003 is used by TETRA network operators, SwMI vendors, terminal manufacturers and system integrators. It is also relevant to engineers and test teams who need to implement or verify barring rules for outgoing voice and data services.

In practice, buyers and quality managers use it to check whether a product or network supports the SS-BOC behaviour they need. Interoperability teams use it when validating roaming, inter-system signalling and the handling of user notifications and acknowledgements.

Which standards are used with SIST EN 300 392-11-18 V1.1.1:2003?

SIST EN 300 392-11-18 V1.1.1:2003 cites these normative and companion standards:

• ETS 300 392-2 - provides the TETRA Air Interface and the definitions for basic service and packet data service used by SS-BOC.
• ETS 300 392-12-18 - the related stage 2 part for BOC in the same TETRA service family.
• ETS 300 392-11-19 - covers Supplementary Service Barring of Incoming Calls (BIC), which is referenced for group identity handling.
• ETS 300 392-10-1 - covers Call diversion, referenced for interaction notes with SS-BOC.
• ETS 300 392-10-6 - covers Call authorized by dispatcher, referenced as a way to permit a barred basic service.

What does the SIST EN 300 392-11-18 V1.1.1:2003 document contain?

The document contains the functional model for SS-BOC, including the relationships between FE1 to FE5 and the call control entities CC and CCA. It also contains message definitions for DEFINE, DEFINE-ACK, INFORM-USER, INFORM-USER-ACK, INTERROGATE, INTERROGATE-ACK and CALL-BARRED.

It includes example information flow sequences for definition, interrogation and operation, both within one system and over the ISI. Clause 4 also provides the FE action lists and the allocation of FEs to physical equipment, which are the parts implementers use for design and integration work.

Several tables describe what fields are mandatory, conditional or optional in each information flow. The figures show how SS-BOC signalling interacts with basic call signalling when a call is barred, which is useful for testing and certification.

Page 7Draft prETS 300 392-11-18: October 19961ScopeThis European Telecommunication Standard (ETS) defines the stage 2 specification of theSupplementary Service Barring of Outgoing Calls (SS-BOC) for the Trans-European Trunked Radio(TETRA) as provided by European operators.SS-BOC enables barring restriction for outgoing calls to be set. SS-BOC specifies the definition,interrogation and operation of the supplementary service. The Switching and Management Infrastructure(SwMI) applies the SS-BOC definitions when the restricted user requests an outgoing service.The SS-BOC actions are defined for the SwMI, for the Mobile Station (MS) and for the Line Station (LS).The SS-BOC information flows may be delivered over the Inter-System Interface (ISI). SS-BOC may alsobe invoked for services, e.g. calls, within one TETRA system or for services that extend over the ISI toseveral TETRA systems.Man-Machine Interface (MMI) and charging principles are outside the scope of this ETS.Stage 2 describes the functional capabilities of the Supplementary Service introduced in stage 1description. Stage 2 identifies the functional capabilities for the management and operation of the servicein the SwMI, in the MS and in the LS. Stage 2 describes also the information flows exchanged betweenthese entities and the flows sent over the ISI.NOTE:The stage 2 description is followed by the stage 3 description, which specifiesthe encoding rules for the information flows and process behaviour for the differententities in the SwMI, in the MS and in the LS.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications.

1 Scope
This European Telecommunication Standard (ETS) defines the stage 2 specification of the
Supplementary Service Barring of Outgoing Calls (SS-BOC) for the Trans-European Trunked Radio
(TETRA) as provided by European operators.
SS-BOC enables barring restriction for outgoing calls to be set. SS-BOC specifies the definition,
interrogation and operation of the supplementary service. The Switching and Management Infrastructure
(SwMI) applies the SS-BOC definitions when the restricted user requests an outgoing service.
The SS-BOC actions are defined for the SwMI, for the Mobile Station (MS) and for the Line Station (LS).
The SS-BOC information flows may be delivered over the Inter-System Interface (ISI). SS-BOC may also
be invoked for services, e.g. calls, within one TETRA system or for services that extend over the ISI to
several TETRA systems.
Man-Machine Interface (MMI) and charging principles are outside the scope of this ETS.
Stage 2 describes the functional capabilities of the Supplementary Service introduced in stage 1
description. Stage 2 identifies the functional capabilities for the management and operation of the service
in the SwMI, in the MS and in the LS. Stage 2 describes also the information flows exchanged between
these entities and the flows sent over the ISI.
NOTE: The stage 2 description is followed by the stage 3 description, which specifies
the encoding rules for the information flows and process behaviour for the different
entities in the SwMI, in the MS and in the LS.

TETRA services. By definition, a mobile station contains at least one Mobile Radio Stack.
packet data service: Connection oriented packet mode data service and connectionless packet mode
data service, see ETS 300 392-2 [1] clauses 24 and 26.
SS-BOC definition indication: The SS-BOC definition indication may be sent to the affected user(s)
to inform him about the definition made on his behalf.
SS-BOC operation: The barring of a call in accordance with the SS-BOC definition.
Switching and Management Infrastructure (SwMI): All of the TETRA equipment for a Voice plus Data
(V+D) network except for subscriber terminals. The SwMI enables subscriber terminals to communicate
