SIST ETS 300 392-10-9 E1:2003 is the Slovenian standard identical to ETS 300 392-10-9 Edition 1 from ETSI for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies the stage 1 description of the supplementary service Access priority (SS-AP), which gives a user preferential access to the TETRA system when the radio link is congested. It is written for people who need to understand how access priority is provided, used, and interacts with other TETRA supplementary services.

What does SIST ETS 300 392-10-9 E1:2003 specify?

SIST ETS 300 392-10-9 E1:2003 specifies the user-level service description for Supplementary Service Access Priority (SS-AP) in TETRA V+D. It focuses on what the service does, how it behaves in normal and exceptional cases, and how it relates to other supplementary services.

The scope says stage 1 is an overall service description from the user point of view, not a human-interface design. It also states that charging principles are outside scope.

The document is organized into:

• Clause 1 Scope
• Clause 2 Normative references
• Clause 3 Definitions and abbreviations
• Clause 4 SS-AP stage 1 specification
• Figures 1 and 2, which give the overall SDL view of the service behavior

What are the key requirements of SIST ETS 300 392-10-9 E1:2003?

SIST ETS 300 392-10-9 E1:2003 defines how SS-AP works when network access is congested, and what the mobile and the network each do.

• SS-AP provides preferential uplink access when radio link congestion occurs. In practice, this means the service is about getting a call attempt or data access started, not about giving priority after a connection is already established.
• The service uses an Access Priority Level (APL). The APL is normally stored in the Mobile Station (MS), may also be stored in the Switching and Management Infrastructure (SwMI), and is checked before the initial call set-up attempt. This matters because the mobile must compare its own APL with the broadcast access level before trying to access the network.
• The SwMI periodically broadcasts access information. If the user’s APL is greater than or equal to the broadcast APL, access is allowed; if not, the access attempt is delayed. This gives operators a way to control random access during congestion.
• SS-AP applies to all TETRA circuit mode teleservices, all TETRA circuit mode bearer services, and the Short Data Service (SDS). That means the same access-priority concept can be used across voice and data services.
• Provision and withdrawal are by pre-arrangement with the service provider, and SS-AP is handled on a per TETRA number basis (Individual TETRA Subscriber Identity (ITSI) or Group TETRA Subscriber Identity (GTSI)). This tells buyers and operators that SS-AP is a subscribed service, not an automatic network behavior.
• The service includes procedures for activation, deactivation, definition, registration, and interrogation. Definition can be performed by an authorized user, such as a dispatcher, and interrogation can be local or remote. In practice, this means administrators need a way to set and check which priority a user has been given.
• Clause 4.3 states that SS-AP has no interaction with most listed supplementary services, with specific notes for Pre-emptive Priority Call (SS-PPC), Ambience Listening (SS-AL), and Dynamic Group Number Assignment (DGNA). This helps implementers avoid unintended service conflicts.
• When a served user moves to another SwMI, the user shall be informed of the existence of, or change to, the APL. That is important for roaming or inter-network operation.

What terms does SIST ETS 300 392-10-9 E1:2003 define?

• Access control - prevention of unauthorized use of resources.
• Access priority level (APL) - the value used during initial call set-up to determine whether a user may gain access during congestion.
• Served user - the user making the service request.
• Switching and Management Infrastructure (SwMI) - all TETRA V+D network equipment except subscriber terminals.
• Individual TETRA Subscriber Identity (ITSI) - the identity used for an individual subscriber.
• Group TETRA Subscriber Identity (GTSI) - the identity used for a group subscriber.
• Mobile Station (MS) - the mobile equipment that stores the APL and takes access decisions.

Who uses SIST ETS 300 392-10-9 E1:2003?

SIST ETS 300 392-10-9 E1:2003 is used by TETRA network operators, service providers, terminal and infrastructure vendors, and system integrators. It is relevant to engineers and administrators who configure priority access, dispatchers who may define priority for users, and buyers who need to specify network behavior for congested situations.

It is also useful for organizations that rely on TETRA voice and data services and need controlled access for selected users or call types.

What changed in SIST ETS 300 392-10-9 E1:2003 from the previous edition?

SIST ETS 300 392-10-9 E1:2003 is identified as identical to ETS 300 392-10-9 Edition 1, and the history shows it as the first edition issued in April 1996.

Which standards are used with SIST ETS 300 392-10-9 E1:2003?

• CCITT Recommendation I.130 - used for the method of characterizing telecommunication services supported by an ISDN and network capabilities.
• ITU-T Recommendation Z.100 - provides the Specification and Description Language (SDL) used for the overall service model.

What does the SIST ETS 300 392-10-9 E1:2003 document contain?

The document contains the stage 1 service description, the procedures for provision, activation, interrogation, and invocation, and the service interactions with other TETRA supplementary services. It also includes exceptional cases, such as rejected interrogation requests or denied access attempts.

Figures 1 and 2 present the overall SDL behavior of SS-AP. They show how the SwMI broadcasts the access level, how the MS compares that level with the user’s APL, and how access is permitted or blocked accordingly.

Page 7ETS 300 392-10-09: April 19961ScopeThis European Telecommunication Standard (ETS) defines the stage 1 specifications of theSupplementary Service Access Priority (SS-AP) for the Trans-European Trunked RAdio (TETRA). Stage 1is an overall service description from the users point of view but does not deal with the details of thehuman interface itself.This ETS specifies the service description of the supplementary service and the procedures to beexpected with successful and unsuccessful outcomes. In addition this ETS specifies the interactions withother TETRA supplementary services and inter-working considerations.Charging principles are outside the scope of this ETS.The SS-AP enables a user to have preferential access to the TETRA system in times of radio linkcongestion.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications.
