SIST EN 300 392-10-6 V1.4.1:2006 is the Slovenian adoption of the ETSI standard for Terrestrial Trunked Radio (TETRA) Voice plus Data supplementary service Call Authorized by Dispatcher (SS-CAD). It defines the stage 1 service description for how dispatcher approval is requested and applied before certain TETRA calls proceed, including the interaction options with SS-PPC. The document is for people who need to understand when calls are intercepted, authorized, diverted, or rejected in a TETRA network.

What does SIST EN 300 392-10-6 V1.4.1:2006 specify?

SIST EN 300 392-10-6 V1.4.1:2006 specifies the user-level service behavior of SS-CAD for TETRA. It covers the service description, the normal and exceptional procedures, the interactions with other supplementary services, and interworking considerations. Charging principles and human interface details are outside its scope.

The document is organized into clauses for scope, references, definitions and abbreviations, and the SS-CAD stage 1 specification. It ends with an informative annex listing change requests.

What are the key requirements of SIST EN 300 392-10-6 V1.4.1:2006?

SS-CAD is a dispatcher-controlled authorization service. Clause 4 states that predefined TETRA calls shall not proceed until a dispatcher has verified and approved them, which matters in practice because the call setup can pause while the authorization decision is made.

The service applies to all TETRA speech and circuit mode data services. That means the same dispatcher-approval logic can be used across speech and data calls, not only one traffic type.

Provision is done by prior arrangement with the service provider, and the service may be withdrawn by the provider. Clause 4.2.1 also defines the main implementation options: restricted basic service, restricted destination address, restricted source address, and restricted area. In practice, the authorized user has to identify which users, addresses, services, or areas are to be controlled and provide the dispatcher address for approval.

Before an SS-CAD definition is completed, the restricted users have to be verified against the authorized user’s jurisdiction. The service provider then returns acceptance or rejection. This matters because an SS-CAD profile is not just entered - it is checked before it becomes active.

Interrogation is supported on a per-number basis through the SwMI. The response may report the restricted user, whether the service is active or inactive, the applicable basic services, destination addresses, source addresses, and restricted area. An optional capability lets the restricted user interrogate its own SS-CAD restrictions, which is useful for confirming what is currently controlled.

For invocation and operation, the infrastructure checks the calling or called address, the area, and the basic service request. If authorization is needed, the call may be suspended and sent to the dispatcher, or diverted directly to the dispatcher. If the dispatcher rejects the request, the call is disconnected and the restricted user is informed that authority was not granted.

SS-CAD has defined relationships with other supplementary services. It does not interact with many of them, but it overrides SS-BOC and SS-BIC. Clause 4.3.21 also gives three SS-CAD and SS-PPC interaction options, ranging from SS-PPC taking precedence to no interaction or profile-based behavior. This is important for operators because priority behavior has to match the local service policy.

SS-CAD is also available across the intersystem interface. If a restricted user roams to a visited SwMI, the call request may still be routed back to the home TETRA system for dispatcher authorization.

What terms does SIST EN 300 392-10-6 V1.4.1:2006 define?

• Call Authorized by Dispatcher (SS-CAD) - A supplementary service in which a dispatcher verifies and approves a call request before the call can proceed.
• Authorized user - The user who can define SS-CAD and can also activate, deactivate, and interrogate it.
• Dispatcher - The user to whom the authorization request is sent.
• Restricted user - The user whose calls must be authorized by a dispatcher before proceeding; this may be the calling user A, the called user B, or both.
• Switching and Management Infrastructure (SwMI) - The TETRA network infrastructure that supports service handling and interrogation.
• Specification and Description Language (SDL) - The language used for the overall behavioral model shown for SS-CAD.
• Voice Plus Data (V+D) - The TETRA service family covered by the multipart deliverable.

Who uses SIST EN 300 392-10-6 V1.4.1:2006?

TETRA network operators use SIST EN 300 392-10-6 V1.4.1:2006 to define when dispatcher approval is required and how the call control behavior should work. Service providers use it when provisioning, withdrawing, and checking SS-CAD subscriptions.

It is also relevant to system integrators, equipment vendors, and network planners implementing TETRA supplementary services. Quality and operations teams use it to confirm how restricted users, dispatcher approval, roaming calls, and service interactions are supposed to behave.

What changed in SIST EN 300 392-10-6 V1.4.1:2006 from the previous edition?

The document history shows V1.4.1 published in August 2006 after V1.4.0 in March 2006. Annex A lists change requests for alignment with stage 3 and editorial corrections, and a change request for SS-PPC interaction.

Which standards are used with SIST EN 300 392-10-6 V1.4.1:2006?

• ITU-T Recommendation Z.100 - Provides the SDL notation used for the overall SS-CAD behavior model.
• ITU-T Recommendation I.210 - Provides the principles for describing telecommunication services and the stage-based method used for supplementary services.

What does the SIST EN 300 392-10-6 V1.4.1:2006 document contain?

Clause 4 contains the service rules in procedural form, including provision, activation, interrogation, invocation, exceptional outcomes, and service interactions. The document uses implementation-option tables to relate source, destination, basic service, and area conditions to authorization behavior.

It also includes a table for whether the caller receives interception information, and a table for SS-CAD and SS-PPC interaction options. Figure 1 gives an overall SDL model of the network behavior, showing the request, interception, authorization, rejection, and release flow. That makes the document useful for design reviews, implementation work, and service behavior checking.

Introduction Supplementary services specifications are produced in three stages, according to the method described in ITU-T Recommendation I.210 [2]. The present document contains the stage 1 specification of SS-CAD. The stage 1 descriptions specify the supplementary services as seen by users of networks. The Call Authorized by Dispatcher service is specific to TETRA. SIST EN 300 392-10-6 V1.4.1:2006

1 Scope The present document defines the stage 1 specifications of the Supplementary Service Call Authorized by Dispatcher (SS-CAD) for the Terrestrial Trunked Radio (TETRA) system. Stage 1 is an overall service description from the users point of view but does not deal with the details of the human interface itself. The present document specifies the service description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes. In addition, the present document specifies the interactions with other TETRA supplementary services and interworking considerations. Charging principles are outside the scope of the present document. The SS-CAD ensures that predefined TETRA calls do not proceed without first being authorized by a dispatcher. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
