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

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.

Dec 29, 2022 · The SMF sets configuration parameters in the UPF that define traffic steering parameters and ensure the appropriate routing of packets. It also guarantees the delivery of incoming packets though a Downlink (DL) data notification.

The AMF refers to ‘Access and Mobility Management Function’. From its name, the main function of the AMF, is to control the access of the UE, to the 5G network. And the make mobility management for the UE. The AMF, is the first point in the control plane, that connects to the gNB.

Apr 6, 2023 · In 5G, SMF stands for “Session Management Function.” It is a core network element responsible for managing the sessions between user devices and the network. Section 6.2.2 of 3GPP’s Technical Specification 23.501 provides a detailed description of …

Entender SMF Interacciones con AMF y UPF. La relación entre la Función de Gestión de Acceso y Movilidad (AMF), la Función de Gestión de Sesiones (SMF) y la Función de Plano de Usuario (UPF) es crucial para que la arquitectura 5G tenga una gestión de sesiones eficiente.

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.

Dec 30, 2023 · AMF (Access and Mobility Management Function): SMF interacts with AMF for user authentication, mobility-related information exchange, and context transfer during handovers. PCF (Policy Control Function) : SMF interacts with PCF to retrieve and enforce policies related to QoS, charging, and data handling based on subscription profiles and ...

shows the interaction that exist between the NF services in the network functions described by point-to-point reference point (e.g. N11) between any two network functions (e.g. AMF and SMF). Rel-17, ...

Feb 22, 2019 · Another major difference in 5GC’s CP is the structure, because it has different functional separation of Access and Mobility Functions (AMF) and Session Management Functions (SMF). 5GC includes the separation of UP and CP functions of the gateway, which was an evolution of the gateway CP/UP separation (CUPS) introduced in EPC Release 14.
