In order to provide the general context the course briefly introduces the overall roles of all the major 5G Network Functions (NFs), and the outline of the basic 5G traffic cases – the 5G Registration and PDU Session Establishment.

The course focuses on the 5G Policy Control Function (PCF), explaining the Policy Control model used to enforce both the subscription-specific Access and Mobility Management and the service-specific QoS, routing and charging handling rules. 3GPP definitions for User Plane resources are presented, as well as external AF traffic influencing. A short part on the 5G Charging Control is included.
