UE role in 5G Standalone Access Registration. Covers RACH, RRC Setup and Registration with the AMF.
The gNB establishes an RRC connection with the UE and then acts as a conduit in UE registration with the AMF.
An overview of AMF interactions.
The UE is switching registration from the Old AMF to the New AMF. This New AMF also coordinates the registration procedure with other 5G Core Network components.
The AUSF authenticates the UE during the registration procedure.
The UDM generates the authentication vectors and processes registration and de-registration requests.
The PCF supports creation and deletion of policy associations. The PCF also registers with the AMF for subscriber events.
The SMF handles the control plane functions of session management. It allocates and configures the UPF data plane via the N4 interface.
The UPF handles the data plane interfaces. It routes downlink traffic from the Internet to the gNB. The UPF receives uplink traffic from the gNB and routes it to the Internet.
