Quality of Service and Cybersecurity in Critical Communications

This document presents a series of discussions and speeches focused on Quality of Service (QoS), Priority and Pre-emption (QPP), and cybersecurity strategies for critical communications. It outlines the development of the TCCA QPP Implementation Guide, which details technical best practices for implementing QPP in 3GPP mission-critical mobile broadband networks. The guide aims to provide a common industry vision for QPP implementation. Additionally, practical experiences regarding broadband network performance for mission-critical communication are shared, including field results on push-to-talk capacity and performance testing. The document also addresses the need for quantum-safe networks to protect critical communications from emerging threats posed by quantum computing. Cybersecurity challenges specific to critical communications networks are explored, along with strategies for securing telecom-specific assets and preventing unauthorized access. The importance of creating a resilient ecosystem for uninterrupted communications is emphasized throughout the discussions.
