SIST ETS 300 392-10-10 E1:2003 is a Slovenian standard published by SIST that is identical to ETS 300 392-10-10 Edition 1. It defines the TETRA Voice plus Data (V+D) supplementary service stage 1 for Priority Call (PC), from the user and service point of view. In practice, it tells TETRA service providers, network operators, and implementers how priority calling is supposed to behave, including setup, congestion handling, and interaction with other supplementary services.

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

SIST ETS 300 392-10-10 E1:2003 specifies the stage 1 description of Supplementary Service Priority Call (SS-PC) for Terrestrial Trunked Radio (TETRA). It covers the service behavior, the expected successful and unsuccessful procedures, interactions with other TETRA supplementary services, and inter-working considerations.

The scope focuses on the service as seen by the user, not the detailed human interface. Charging principles are outside the scope. The document is organized into scope, normative references, definitions and abbreviations, the SS-PC specification, and an overall SDL figure.

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

SS-PC gives preferential access to network resources for calls sent with priority status, as described in 4.1. That matters because, during congestion, higher-priority calls are meant to get resources before lower-priority calls.

The priority level is sent with the initial call set-up message, or the network may apply a default level if the user does not choose one. The level may also be indicated to the called user as normal call control information. In practice, the network and terminal need to support priority handling from the start of call setup, not as an afterthought.

The priority level applies to network resources across the infrastructure and to the radio link at the called user, but not to the initial uplink access. A typical scenario may use eight priority levels, and the queuing procedure is an operator option. This gives operators some control over how calls are ordered under load.

SS-PC is applicable to all TETRA circuit mode teleservices, all TETRA circuit mode bearer services except packet data services, and the TETRA Short Data Service (SDS). That means implementers need to support priority calling across the main circuit-mode service types, including short data.

Provision and withdrawal are by pre-arrangement with the service provider, on a per TETRA number basis using ITSI or GTSI. A user can be given a range of priority levels for per-call selection, and for a GTSI each group member is downloaded with the associated priority level or range. This affects subscription management and group administration.

Clause 4.2 allows optional remote activation, deactivation, definition, registration, and interrogation. Interrogation can be local, remote, or both, and the SwMI can report whether the service is provided, the default priority level, the priority level range, and the registered ITSI range. Cancellation is not applicable. In practice, this is the control information operators and support systems need to manage who can use SS-PC.

If a user requests a priority level outside the allowed range, the infrastructure adjusts it to the maximum or minimum applicable value and continues the call, with notification possible. If the served user lacks the appropriate profile, SS-PC is rejected. Under congestion, the infrastructure compares priority levels and assigns resources to the highest-priority call attempt.

Clause 4.3 shows how SS-PC relates to other supplementary services. Many services have no interaction, but some can be invoked together, such as List Search Call, Short Number Addressing, Call Completion to Busy Subscriber, and Call Completion on No Reply. Pre-emptive Priority Call (SS-PPC) always takes precedence over SS-PC, and Barring of Incoming Calls prevents an incoming SS-PC from being offered to the barred user.

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

Access control is the prevention of unauthorized use of resources, including use in an unauthorized manner.

Authorised user is a user allowed to change the range of priority levels for the served user’s calls.

Priority level is a pre-agreed value assigned to an Individual TETRA Subscriber Identity (ITSI) or Group TETRA Subscriber Identity (GTSI) on a per-call basis to determine access priority during congestion.

Served user means the call originator.

SwMI means Switching and Management Infrastructure, the network side that controls service behavior.

ITSI means Individual TETRA Subscriber Identity, and GTSI means Group TETRA Subscriber Identity.

SS-PC means Priority Call, the supplementary service defined by this standard.

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

This standard is used by TETRA service providers and network operators when they provision priority access, set default levels, and manage subscriptions. It is also used by SwMI implementers and terminal or infrastructure suppliers when they design call setup, congestion handling, and user notifications.

System integrators and test teams use it to check that priority calls behave correctly with other supplementary services and across inter-working situations. It is also useful for buyers and technical evaluators who need to know whether a TETRA system supports priority calling on the required service types.

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

SIST ETS 300 392-10-10 E1:2003 corresponds to ETS 300 392-10-10 Edition 1, the first edition of this document.

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

The standard cites CCITT Recommendation I.130 for the method used to characterize telecommunication services and network capabilities. It cites ITU-T Recommendation Z.100 for Specification and Description Language (SDL), which is used for the overall behavior model in Figure 1.

The foreword places this document within the TETRA series as Part 10, alongside related parts for general network design, air interface, inter-working, gateways, terminal equipment interface, security, management services, performance objectives, supplementary services stage 2 and stage 3, SDL model, PICS proforma, extended operations, and gateways for supplementary services.

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

Clause 4.2 lays out the normal and exceptional procedures for provision, activation, deactivation, definition, registration, interrogation, and invocation. Clause 4.3 gives the interaction rules with 30 named supplementary services, which is useful when a system combines SS-PC with forwarding, barring, call waiting, group services, or call completion features.

Clause 4.4 covers inter-working considerations for movement to another SwMI. Clause 4.5 contains the overall SDL in Figure 1, which models the call flow for SS-PC and shows how calls are routed, queued, or adjusted when priority is involved.

1 Scope
This European Telecommunication Standard (ETS) defines the stage 1 specifications of the
Supplementary Service Priority Call (SS-PC) for the Trans-European 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 inter-working considerations.
Charging principles are outside the scope of this ETS.
The SS-PC enables a user to have preferential access to the network resources in the TETRA system.
