The gNodeB (gNB) is the central component in a 5G network that communicates with user equipment (UE) and is responsible for managing radio resources. The gNB connects to the 5G core network through the Next Generation Core (NGC) and the Access and Mobility Management Function (AMF). One of the key elements in the NGC is the gNodeB Application Function (gNAF), which is responsible for handling the registration and mobility management of the gNB.

The gNB communicates with the User Plane Function (UPF) in the NGC through the gNodeB Application Protocol (gNAP). The gNAP is used to establish and manage data sessions between the gNB and the UPF, allowing for the transfer of user data. The gNB also communicates with the Session Management Function (SMF) in the NGC to handle session management and control plane functions.

Overall, the gNB plays a crucial role in the 5G network by enabling communication between user equipment and the core network. Its functions include radio resource management, mobility management, and data session establishment, making it a key component in delivering high-speed, low-latency connectivity to users.
