Overview

SIST ETS 300 392-10-10 E1:2003 is a Slovenian adoption of the European Telecommunications Standard that defines the stage 1 requirements for the Priority Call (PC) supplementary service within the Terrestrial Trunked Radio (TETRA) system. TETRA is a critical digital trunked radio standard widely used for professional mobile radio (PMR) and public safety communications across Europe. Part 10, Sub-part 10 of this multi-part standard focuses on enabling network users to establish calls with preferential access, ensuring important communications are prioritized during network congestion.

This standard addresses the anticipated needs of digital trunked systems, specifies the services to be offered, and examines relevant spectrum requirements and interface characteristics. It is developed by SIST in close alignment with European Telecommunications Standards Institute (ETSI) guidance.

Key Topics

• Priority Call (PC) Service: Defines how authorized TETRA users can initiate calls with priority, ensuring critical communications are handled first during periods of network congestion.
• User Access and Authorization:
  • Describes how priority levels are assigned to individual or group subscribers (ITSI/GTSI).
  • Details procedures for activation, deactivation, remote control, and interrogation of priority levels.
• Priority Level Management:
  • Supports multiple priority levels which can be allocated dynamically or set by default by the network.
  • Network resources are distributed according to the assigned call priority, with higher priority calls pre-empting lower priority ones.
• Service Applicability:
  • Applies to all TETRA circuit-mode teleservices and bearer services, except for packet data.
  • Supports TETRA Short Data Service (SDS).
• Interactions with Other Supplementary Services:
  • Outlines compatibility and behavior when Priority Call operates in conjunction with other TETRA services (e.g., call forwarding, call waiting).
• Operational and Exceptional Procedures:
  • Specifies standard and exceptional cases for call setup, service invocation, and error handling.

Applications

The Priority Call supplementary service as defined in SIST ETS 300 392-10-10 E1:2003 is vital for organizations where communications reliability is paramount, especially in emergency or critical operational environments. Practical applications include:

• Public Safety Communications: Police, fire, and ambulance services rely on Priority Call to guarantee that emergency communications are completed even during peak traffic.
• Transport and Utilities: Railway, airport, and utility control centers use Priority Call to maintain command and control during incidents or disruptions.
• Disaster Response: Ensures that first responders and coordination centers can maintain communications hierarchy in large-scale incidents.
• Industrial Security: Facilities with high security requirements, such as power plants or chemical industries, use PC to support control room-to-field communications.

Priority Call supports operational continuity and incident management by allowing fast, assured access to network resources based on assigned importance.

Related Standards

The Priority Call supplementary service is part of a comprehensive suite of TETRA standards. Key related documents include:

• SIST ETS 300 392-10 (all sub-parts): Defines supplementary services and overall system architecture.
• SIST ETS 300 392-1: General network design for TETRA.
• SIST ETS 300 392-2: Air Interface (AI) protocols.
• SIST ETS 300 392-7: Security aspects of TETRA communications.
• ETSI EN 300 392 Series: The parent series managed by ETSI covering the full TETRA specification.

By adhering to these standards, organizations ensure interoperability, reliability, and regulatory compliance in the deployment and use of TETRA Voice plus Data (V+D) services, with Priority Call forming a cornerstone for mission-critical communications in Europe.

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.
