name: SMF
full_form: System Management Function
context: scenario with UE registered to the same VPLMN for 3GPP access and non-3GPP access. - The SMF in HPLMN shall support charging for MA PDU Connectivity Service in roaming Home Routed scenario with UE registered in different PLMNs. - The SMF shall support the charging of redundant transmission for high reliability communication. - The SMF shall support the charging of 5G LAN VN group communication. - The SMF shall support the charging of 5GS CIoT. - The SMF may support the charging of time sensitive communication traffic. - The SMF may support the IMS data channel volume-based charging. - - The SMF may support PDU session charging of 5G multicast services. - The SMF may support the charging of 5GS satellite backhaul. - The SMF may support the converged charging for NPN. - - The SMF may support the charging of 5GS satellite access.
description: The Session Management Function (SMF) is a network function in the 5G core network responsible for managing PDU sessions, including session establishment, modification, and termination. It also handles charging and billing for various services such as MA PDU Connectivity Service, redundant transmission, 5G LAN VN group communication, 5GS CIoT, time-sensitive communication traffic, IMS data channel volume-based charging, 5G multicast services, and 5GS satellite backhaul.
explanation: The SMF is classified as a Network Function based on its role in managing PDU sessions and handling charging for various services within the network, as highlighted by the context from 3GPP TS 32.255.
