As part of the set of information relevant for each mission criticalcommunication services’ use cases, types of traffic are described (e.g. data, voice, ShortMessage Service), together with relevant scenarios where each use case applies (e.g.domestic, roaming). Different network architectures are also described together withpotential technical requirements as per network architecture (e.g. 4G, 5G SA/NSA, QoS):4G, 5G NSA are covered as phase 1 document release and 5G SA is covered as phase 2document release. This document covers phase 1. Additionally, legal aspects are highlighted (e.g. Legal Interception, Roaming Service LevelAgreement) as well as interaction and/or interworking with network related pr
