name: MC
full_form: Mission Critical
context: The MC system security architecture provides protection both between MC clients, between the MC client and the MC domain, and also between MC domains. MC system security on the client is bound to the MC user associated with the client and not to the MC UE. Consequently, user authentication and authorisation to the MC domain is required prior to access to the majority of MC services. Application plane signalling security allows protection of MC-specific signalling from all entities outside of the MC system (potentially including the SIP core). Application plane signalling security is applied from the MC client to the client's primary MC domain. It may also be applied between MC domains. Media security allows protection of MC media within the MC system. It is applied end-to-end between MC clients or in some cases from the MC client to the MCX server (e.g. One-to-server video push or one-from-server video pull). Under normal operation however, MC network entities such as the MCX Servers
description: Mission Critical (MC) refers to a set of services and features in telecommunications that are critical for public safety, emergency response, and other mission-critical communications. It encompasses various aspects, including system security architecture, user authentication, authorization, and protection of MC-specific signaling and media.
explanation: The context provided highlights the importance of Mission Critical (MC) in telecommunications, specifically in relation to system security, user authentication, and protection of MC services. Given its unique role and focus on critical communications, MC is best classified as Miscellaneous, as it does not fit neatly into other categories such as Network Function or Protocol.
