Overview
SIST EN 300 392-10-14 V1.2.1:2003 is a Slovenian national standard, identical to EN 300 392-10-14, published by the Slovenski inštitut za standardizacijo (SIST). This standard, part of the broader Terrestrial Trunked Radio (TETRA) series, defines the supplementary service stage 1 specifications for Late Entry (LE) functionality in TETRA Voice plus Data (V+D) networks. The Late Entry (SS-LE) service enables users to join ongoing multipoint voice or data calls, enhancing communication flexibility and operational efficiency in trunked radio systems.
The document clarifies user-level service descriptions and expected behaviors for the SS-LE, not involving detailed human interface specifics or charging principles. SS-LE provides mechanisms for late joiners to be integrated reliably into active group calls, which is vital in mission-critical and professional communications environments.

Key Topics
Late Entry (SS-LE) Definition
SS-LE enables radio users who are not involved at the initiation of a group call to be notified and, if desired, to join that call in progress.Service Applicability
The standard is applicable to TETRA multipoint speech and data circuit mode services, including group and broadcast calls.Provisioning & Activation
- SS-LE may be provided either by pre-arrangement for specific group identities (GTSI) or directly to authorized users.
- Activation and deactivation processes depend on service provisioning and user authorization.
Operational Procedures
- The infrastructure issues late entry indications during the active period of a multipoint call.
- Two main indication types:
- Late Entry Broadcast: Users can join directly if resources are available.
- Late Entry Paging: Users must request channel access to participate.
- Forced late entry scenarios allow priorities based on group and network settings.
Error & Exceptional Scenarios
The standard outlines notification mechanisms and reasons for denial when definition or interrogation requests cannot be fulfilled (e.g., unauthorized user, unsupported service, invalid parameters).Interworking & Interactions
- SS-LE is designed to operate independently of other TETRA supplementary services with specific outlined exceptions.
- Supported interworking across Switching and Management Infrastructures (SwMIs) when both systems support SS-LE.
Applications
Implementing SS-LE in TETRA networks brings practical value in sectors where group communication and operational continuity are essential:
Public Safety & Emergency Services:
Fire, police, and rescue teams can ensure all relevant personnel are quickly integrated into ongoing coordination calls, even if they become available after call start.Transportation & Utilities:
Control centers can update and include field operators or maintenance staff in active discussions in real time.Industrial & Commercial Operations:
Teams operating in dynamic or hazardous environments can maintain group cohesion and awareness by allowing late joiners to instantly participate in critical conversations.
This enhances group communication flexibility, minimizes information loss, and improves overall situational awareness.
