Explore the functions of 5G NR network nodes, including AMF, UPF, SMF, PCF, UDM, DN, AUSF, and AF, as defined in 3GPP specifications.

Jan 26, 2021 · SMF Functions in 5G: There will be no PND in 5G. So, All IP allocations and session management will be done by SMF (Session Management Function). The SMF will perform the following main functions: Session Management. UE IP address allocation and management. Selection and control of UP function.

From its name, The SMF mainly is responsible for session management. This means it is responsible to establish, modify or terminate the data session. In addition, the SMF is responsible to select and control the UPF. It selects which UPF should serve each data session.

SMF stands for Session Management Function. Simply put, it collects all the informations related to PDU session management from various network components (e.g, UPF, PCF, UDM) and controls / orchastrates those network components based on request from AMF.

Apr 30, 2020 · SMF service communicates with different NFs, such as UDM, AMF, PCF, CHF and so on, when the session is brought up. The NF discovery is based on set of filters that are associated with the session.

Dec 15, 2023 · In 5G (Fifth Generation) networks, the Access and Mobility Management Function (AMF) and Session Management Function (SMF) are two essential components that play crucial roles in managing user access and mobility, as well as session establishment and management.
