name: UPF
full_form: User Plane Function
context: In addition to the critical assets of a GNP has been described in clause 5.2 of the present document, the critical assets specific to the UPF to be protected are: - UPF Application; - User plane data; - Session related data, e.g. CN Tunnel information, packet detection rules, network usage, traffic detection information, and etc.; - Security data, i.e. cryptographic materials for N3, N4 and N9 interfaces - The interfaces of the UPF to be protected and which are within SECAM scope: - N3 interface between the UPF and the gNB/ng-eNB - N4 interface between the UPF and the SMF - N6 interface between the UPF and the DN - N9 interface between two UPFs - Console interface, for local access: local interface on the UPF - OAM interface, for remote access: interface between the UPF and the OAM system NOTE 1: The detailed interfaces of the UPF class are described in clause 4 of the present document. - UPF Software: binary code or executable code NOTE 2: UPF files may be any file owned by a user
description: The User Plane Function (UPF) is a critical network component responsible for handling user plane data, session-related information, and security data within the 5G core network. It interacts with other network functions through specific interfaces, such as N3, N4, N6, and N9, to facilitate communication and data exchange.
explanation: The context explicitly describes the UPF's role in managing user plane data, session information, and security data, and its interactions with other network components through defined interfaces. This aligns with the definition of a Network Function, which includes virtualized or dedicated hardware components within telecommunications networks.
