SIST EN 300 392-10-18 V1.3.1:2005 is the Slovenian standard published by SIST and identical to ETSI EN 300 392-10-18 V1.3.1. It defines the Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) stage 1 service description for Barring of Outgoing Calls (BOC). In practice, it tells TETRA service providers and network designers how outgoing-call barring is set up, invoked, and combined with other supplementary services.

What does SIST EN 300 392-10-18 V1.3.1:2005 specify?

SIST EN 300 392-10-18 V1.3.1:2005 specifies the stage 1 description of the Barring of Outgoing Calls supplementary service for TETRA. Stage 1 gives the service view from the user side, including how the service behaves and what outcomes users should expect, but not the detailed human-interface design.

The document covers service description, procedures for normal and exceptional operation, interactions with other TETRA supplementary services, and interworking considerations. Charging principles are outside its scope.

The body of the document is organized into Scope, References, Definitions and abbreviations, and the SS-BOC stage 1 specification with subsections for description, procedures, interactions, interworking, and an overall SDL view.

What are the key requirements of SIST EN 300 392-10-18 V1.3.1:2005?

Service meaning and applicability

SIST EN 300 392-10-18 V1.3.1:2005 defines BOC as a facility that bars certain outgoing calls. The service provider can set the barring, and an authorized user can apply or remove it for affected users.

BOC is defined by ranges of barred numbers, with exceptions allowed for closed user groups and individual numbers inside barred ranges. This matters because a network can block broad number ranges while still allowing specific approved destinations.

The same barring ranges and exceptions may be applied independently to circuit mode speech service, circuit mode data service, and Short Data Service (SDS). The service may also apply independently to TETRA teleservices, bearer services, and short data services.

Provisioning and user control

The service is provided by prior arrangement to affected users, on a per ITSI or GTSI basis. The authorized users and served users are defined when the service is provided.

The service provider may withdraw the service at any time without prior announcement. In practice, operators need clear service records so they know which users are allowed to define barring.

Normal operation

The authorized user may activate or deactivate the service through the definition process, and the service may be permanently activated on provision and deactivated on withdrawal. The authorized user may also set and remove barring for the affected users defined on provision.

Interrogation may be supported by the SwMI, and if it is supported, it shall work per affected user number. Cancellation is not applicable.

When a served user tries to set up a call to a barred number, the system invokes BOC, gives an indication of barring, and rejects the call. The served user can still receive calls, so outgoing barring does not block incoming calls.

Exceptional procedures and error handling

If the infrastructure cannot accept a definition or interrogation request, it returns a cause or failure indication. The document lists typical causes such as user not authorized, unknown TETRA identity, parameters not valid, or insufficient information.

For invocation and operation, if the infrastructure cannot invoke the service, no cause is returned to the calling or served user. That tells implementers how the network should behave when the barring function itself cannot be applied.

Interactions with other supplementary services

BOC has defined relationships with many other services, including precedence rules and non-interactions. For example, it takes precedence over Call Forwarding Unconditional (CFU), Call Forwarding on Busy (CFB), Call Forwarding on No Reply (CFNRy), and Call Forwarding on Not Reachable (CFNRc), and these services cannot be active for the same user at the same time.

BOC also interacts with Call Authorized by Dispatcher (CAD), Short Number Addressing (SNA), and Area Selection (AS). CAD can take precedence, SNA-2 may override BOC, and BOC takes precedence over AS.

Several services simply cannot proceed to a barred address, including Call Report (CR), Call Hold (HOLD), Call Completion to Busy Subscriber (CCBS), Discreet Listening (DL), Ambience Listening (AL), Call Completion on No Reply (CCNR), and Call ReTention (CRT) priority. For a buyer or integrator, these clauses matter because they define where barring stops a call flow and where another service is still allowed to act.

What terms does SIST EN 300 392-10-18 V1.3.1:2005 define?

• Affected user - the user whose outgoing service or services are barred.
• Authorized user - the user permitted to bar outgoing calls of defined users.
• Bearer service - a telecommunications service that carries signals between user-network interfaces.
• Switching and Management Infrastructure (SwMI) - the TETRA network equipment for Voice plus Data (V+D) except subscriber terminals.
• Teleservice - a telecommunications service that includes terminal equipment functions for communication between users according to agreed protocols.
• TETRA - Trans-European Trunked Radio.
• Short Data Service (SDS) - the short data service referenced in the service description and applicability rules.

Who uses SIST EN 300 392-10-18 V1.3.1:2005?

SIST EN 300 392-10-18 V1.3.1:2005 is used by TETRA service providers, SwMI designers, and engineers who configure supplementary services in a V+D network. It is also relevant to people who define service policies for individual users or groups, especially where outgoing-call restrictions must be applied consistently.

Network and system teams use it to decide how barring is provisioned, how users are registered, what happens on a barred call attempt, and how BOC behaves alongside forwarding, priority, and listening services. It is also useful for integration work across the intersystem interface.

What changed in SIST EN 300 392-10-18 V1.3.1:2005 from the previous edition?

The history shows that Version 1.3.1 followed Version 1.3.0 and incorporates change request 001. That change request corrected editorial errors in the interactions with Call Forwarding (CF), affecting clauses 4.3.7, 4.3.8, and 4.3.9.

Which standards are used with SIST EN 300 392-10-18 V1.3.1:2005?

• ITU-T Recommendation Z.100 - provides the Specification and Description Language (SDL) used for the overall dynamic description in Figure 1.
• ETSI EN 300 392-10-4 - provides the Call Forwarding (CF) part that BOC refers to for precedence and mutual activation rules.
• EN 300 392-9, EN 300 392-10, EN 300 392-11, EN 300 392-12, ETS 300 392-13, and EN 300 392-14 - these companion parts place BOC within the wider TETRA V+D supplementary services framework.

What does the SIST EN 300 392-10-18 V1.3.1:2005 document contain?

The document contains the service definition, procedure clauses, interaction clauses, and an overall SDL overview of how the network behaves when BOC is applied. Figure 1 gives the SDL model for service activation, deactivation, call request handling, and rejection behavior.

Annex B contains a change-request table that records the editorial correction included in this version. Annex A gives the bibliography, which supports the service description with related telecommunications references.
