Public Safety as Mission Critical Communication in 5G Overview

CONTENTS

This course examines the public safety services specified by 3GPP as key applications within the Mission Critical use case for 5G networks.

It begins by detailing the stringent Quality of Service requirements of critical communication services, followed by an analysis of 5G Standalone (SA) network capabilities designed to meet these demands. The 3GPP Mission Critical system architecture is introduced, along with the specific 5G SA features — in both the access and core domains — that enable low-latency, high-priority communication for fast-response verticals.

Target AUDIENCE

This course is intended for technical professionals involved in the design, deployment, or operation of mission critical and public safety communication systems for the law enforcement agencies, police forces, defence organisations, and contingency or disaster response agencies.

PREREQUISITES

Participants are expected to have a technical background. Basic knowledge of the Standalone 5G system architecture will enable them to fully benefit from this course.
