The 5G Core Network (5GC) is a key architectural component in 5G networks. It includes various network functions and entities responsible for managing and controlling communication sessions. Some of the fundamental functions within the 5GC include the Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), and Network Slice Selection Function (NSSF).
Policy Control Function (PCF):
The Policy Control Function (PCF) is a critical network function within the 5GC. It is responsible for policy enforcement and control related to Quality of Service (QoS), user access, and network resource allocation. PCF interacts with other network functions to ensure that the network policies are applied according to the operator's and subscriber's requirements.
