SMF stands for Session Management Function. It is a core network function (CNF) in 5G architecture, responsible for session management procedures, such as session establishment, modification, and release. The SMF also handles IP address allocation, policy enforcement, and QoS control for user sessions. It interacts with other network functions like the UPF (User Plane Function) and AMF (Access and Mobility Management Function) to provide seamless connectivity and mobility to users.
