| Straight line represents the data interfaces. As you can easily understand there is no user data between functions which are connected with dashed lines. But when a user attached to a 5G core network -after gNB connection- AMF handles the required operations. UE initiates a PDU session request subsequently AMF routes it SMF. SMF interacts with NRF to discover available UPFs. SMF selects optimal UPF and established the user-plane path (Unlike NSA, SA's SMF fully controls UPF selection in the native 5G core). | Straight line represents the data interfaces.
