SIST EN 300 392-10-6 V1.3.1:2006

• Abstract:

  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.

SIST EN 300 392-10-6 V1.3.1:2006 is the Slovenian adoption of ETSI EN 300 392-10-6 V1.3.1 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies the stage 1 service description for Call Authorized by Dispatcher (SS-CAD), a supplementary service used to make sure defined TETRA calls are approved by a dispatcher before they proceed.

What does SIST EN 300 392-10-6 V1.3.1:2006 specify?

SIST EN 300 392-10-6 V1.3.1:2006 defines SS-CAD from the user-service point of view. It covers service description, normal and exceptional procedures, interactions with other TETRA supplementary services, and interworking considerations. 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-CAD stage 1 specification
• Annex A - Change Requests

What are the key requirements of SIST EN 300 392-10-6 V1.3.1:2006?

SIST EN 300 392-10-6 V1.3.1:2006 says that SS-CAD is a dispatcher-controlled authorization step for calls. In practice, a restricted call request is intercepted until a dispatcher accepts it, and the call only continues after that approval.

Service scope and applicability

Clause 4.1 states that SS-CAD applies to all TETRA speech services and circuit mode data services. It can also apply to incoming calls to specified TETRA addresses, including users and gateways. This matters because system designers must know which call types can be put under dispatcher control.

Provisioning and authorization setup

Clause 4.2.1 says SS-CAD is provided by prior arrangement with the service provider and may be withdrawn by the provider. The authorized user supplies the restricted users, the relevant basic service, the dispatcher address, and, depending on the option, restricted destination, source, or area. That means service setup is a controlled administration task, not an end-user toggle.

Verification and service control

Clause 4.2.1.5 requires verification of restricted users before SS-CAD definition is completed. The service provider then returns acceptance or rejection. Clause 4.2.2 allows activation and deactivation, definition, registration on provision, and interrogation on a per-number basis. For operators, this defines the management actions they must support.

Call handling

Clause 4.2.2.2 says the infrastructure decides whether SS-CAD is invoked using the calling address, called address or 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. In practice, this defines how the network blocks or routes calls until approval arrives.

Exceptional cases

Clause 4.2.3 lists rejection conditions for activation, deactivation, definition, and interrogation, such as invalid identities, unauthorized users, unsupported range, or no dispatcher available. This helps implementers define clear failure responses instead of leaving the user with an unexplained blocked call.

Service interactions

Clause 4.3 says SS-CAD has no interaction with many other supplementary services, but it overrides SS-BOC and SS-BIC, and SS-PPC takes precedence over SS-CAD. It also notes that SS-CAD may override SS-CLIR against the dispatcher and that a call can generate multiple SS-CAD invocations. This is important when several service controls apply to the same call.

Interworking

Clause 4.4 says SS-CAD is available across the intersystem interface. If a restricted user is in a visited SwMI, a call may be routed back to the home TETRA system dispatcher for authorization. That supports consistent control even when users roam.

What terms does SIST EN 300 392-10-6 V1.3.1:2006 define?

• authorized user - the user who defines SS-CAD and may also activate, deactivate, and interrogate it.
• dispatcher - the user who receives the authorization request and approves or rejects the call.
• restricted user - the user whose calls must be authorized before they can proceed.
• SwMI - Switching and Management Infrastructure, the TETRA network infrastructure that handles service control.
• SS-CAD - Call Authorized by Dispatcher, the supplementary service covered by this document.
• V+D - Voice plus Data, the TETRA bearer family covered by the series.
• SDL - Specification and Description Language, used for the overall process model in Clause 4.5.

Who uses SIST EN 300 392-10-6 V1.3.1:2006?

SIST EN 300 392-10-6 V1.3.1:2006 is used by TETRA network operators, service providers, system integrators, and dispatcher-controlled user organizations. They use it to specify service behavior, configure restricted users and dispatcher addresses, and verify how call authorization should work in the network.

What changed in SIST EN 300 392-10-6 V1.3.1:2006 from the previous edition?

SIST EN 300 392-10-6 V1.3.1:2006 updates the earlier V1.3.0 version. Annex A states that the change request aligned selected clauses with stage 3 and included editorial corrections.

Which standards are used with SIST EN 300 392-10-6 V1.3.1:2006?

• ITU-T Recommendation Z.100 - provides the SDL method used for the overall behavioral model in Clause 4.5.
• ITU-T Recommendation I.210 - gives the service-description principles used for the three-stage supplementary service approach.
• EN 300 392-9 - the general requirements part for TETRA supplementary services.
• EN 300 392-11 - stage 2 supplementary services.
• EN 300 392-12 - stage 3 supplementary services.

What does the SIST EN 300 392-10-6 V1.3.1:2006 document contain?

SIST EN 300 392-10-6 V1.3.1:2006 contains two implementation-option tables and an overall SDL model. Clause 4.2.1 uses tables to show which authorization conditions can be linked to source, destination, basic service, and area. It also gives the options for whether the calling user is told that interception is happening and whether the dispatcher number is shown.

Clause 4.5 provides the SDL process for SS-CAD, showing the states and outcomes for intercepting, diverting, accepting, rejecting, and releasing a call. Annex A records the change request history.

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 V1.3.1:2006
