SIST ETS 300 392-10-9 E2:2003 is the Slovene adoption of ETS 300 392-10-9 Edition 2 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies the stage 1 service description of the supplementary service Access Priority (SS-AP) for TETRA users, mobile stations and the Switching and Management Infrastructure (SwMI). In practice, it tells network operators, terminal designers and service administrators how access priority is applied when radio access is congested.

What does SIST ETS 300 392-10-9 E2:2003 specify?

SIST ETS 300 392-10-9 E2:2003 specifies the user-level behavior of SS-AP in TETRA, including when a mobile station may attempt uplink access and how priority is compared with the network broadcast value. The document also defines the service procedures, interactions with other supplementary services, and interworking behavior.

The standard is organized into:

• Scope
• Normative references
• Definitions and abbreviations
• Clause 4, which contains the stage 1 specification
• History

Clause 4 is split into the service description, procedures, interactions with other supplementary services, interworking considerations, and an overall SDL view of the service behavior.

What are the key requirements of SIST ETS 300 392-10-9 E2:2003?

SS-AP is used to let a user gain access to the TETRA system during radio link congestion, with preferential treatment on uplink access. In practical terms, the network can control who may start a call or data transfer when access resources are limited.

Service applicability and priority handling

Clause 4.1.2 applies SS-AP to TETRA circuit mode teleservices, circuit mode bearer services, packet mode data services, Short Data Services (SDS), and supplementary services management. The standard also says the Access Priority Level (APL) is handled in the Mobile Station (MS) and checked against a broadcast APL from the SwMI. This means access can be controlled per service and per subscriber identity.

Provisioning, activation and definition

Clause 4.2.1 says provision and withdrawal are by pre-arrangement with the service provider and are handled per TETRA number, that is, per Individual TETRA Subscriber Identity (ITSI) or Group TETRA Subscriber Identity (GTSI). Clause 4.2.2 says SS-AP is permanently activated in all MSs, while the service provider may activate or deactivate it in the SwMI. An authorized user may define the APL, for example in dispatcher operations.

Registration and interrogation

Clause 4.2.2.3 allows the SwMI to register authorized users who may define or interrogate the service, including their ITSI jurisdiction. Clause 4.2.2.4 requires the SwMI, when interrogation is supported, to provide low and high access priority APLs per service. This gives operators a way to check the current priority settings for a subscriber.

Invocation and operation

Clause 4.2.2.6 describes the core behavior: the SwMI broadcasts an APL, the MS stores it, and the MS compares that broadcast value with the user’s selected priority. If the MS APL is greater than or equal to the broadcast APL, access is allowed; otherwise the terminal must wait. This is the mechanism that controls access during congestion.

Exceptional cases, interactions and roaming

Clause 4.2.3 covers rejection cases such as an unauthorized user or an unknown TETRA identity, and it notes that the SwMI may redefine APLs if an MS tries to access without the right priority. Clause 4.3 states that SS-AP has no interaction with most listed supplementary services, while Pre-emptive Priority Call (SS-PPC) should apply the highest APL. Clause 4.4 says that when an MS moves to another SwMI, it uses default APLs until new APLs are downloaded.

What terms does SIST ETS 300 392-10-9 E2:2003 define?

• Access Priority Level (APL) - The priority value used to decide whether an MS may make an access attempt for a given service.
• Supplementary Service Access Priority (SS-AP) - The TETRA supplementary service that controls access under congestion.
• Mobile Station (MS) - The subscriber terminal that stores and uses the APL.
• Switching and Management Infrastructure (SwMI) - The network side of TETRA, excluding subscriber terminals, that broadcasts and manages APLs.
• Individual TETRA Subscriber Identity (ITSI) - A per-user TETRA identity used for provisioning and control.
• Group TETRA Subscriber Identity (GTSI) - A group identity used for service provisioning and access control.
• served user - The user making the service request.

Who uses SIST ETS 300 392-10-9 E2:2003?

This standard is used by TETRA network operators, SwMI implementers, MS manufacturers, service providers and dispatcher system designers. It is also relevant to quality and conformance teams that need to verify how access priority behaves during congestion, provisioning, interrogation and roaming.

What changed in SIST ETS 300 392-10-9 E2:2003 from the previous edition?

The document history shows a first edition from April 1996 and a second edition from December 1998. The scope describes this version as a revision of the Stage 1 specification after PE resolution of Stages 2 and 3.

Which standards are used with SIST ETS 300 392-10-9 E2:2003?

• CCITT Recommendation I.130 - Gives the method used to characterize telecommunication services supported by an ISDN and network capabilities.
• ITU-T Recommendation Z.100 - Provides Specification and Description Language (SDL), which the standard uses for its overall behavior model.
• ETS 300 392-2 - Provides the TETRA air interface background, including the low and high access priority reference used by SS-AP.
• Part 9: General requirements for supplementary services - Gives the common framework for TETRA supplementary services.
• Part 11: Supplementary services stage 2 - Covers the stage 2 view of supplementary services.
• Part 12: Supplementary services stage 3 - Covers the stage 3 view of supplementary services.

What does the SIST ETS 300 392-10-9 E2:2003 document contain?

Clause 4.2 sets out provisioning, activation, registration, interrogation and exceptional procedures for SS-AP. Clause 4.3 lists interactions with many named supplementary services, which is useful when integrating SS-AP with other TETRA features. Clause 4.5 includes an SDL figure showing the overall MS behavior for SS-AP, so implementers can model how access decisions are made.

1 Scope
This European Telecommunication Standard (ETS) defines the stage 1 specifications of the
Supplementary Service Access Priority (SS-AP) for the Terrestrial Trunked Radio (TETRA). 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.
This ETS specifies the service description of the supplementary service and the procedures to be
expected with successful and unsuccessful outcomes. In addition this ETS specifies the interactions with
other TETRA supplementary services and interworking considerations.
Charging principles are outside the scope of this ETS.
The SS-AP enables to define specific priorities in an MS for uplink random access messages (at the air
interface) for circuit mode or packet mode communications.
2 Normative references
