Theory Intro to PCF PCF is an abbreviation for Policy Control Function. As stated in the name, PCF responsible for managing network policies, ensuring efficient and proper network operations. PCF play a vital role in network slicing, policy enforcement, Charging rules and Quality of service management. Due to the existance of PCF, a network could: a. Enhance User Experience by managing QoS and ensure that resource are allocated efficiently. b. Increase Network Utilization by helping to optimize the use of network resources by dynamically adjusting policies based on network conditions. c. Support for Network Slicing by create and manage QoS for each slices that of course has it's own specific QoS.

image Step-by-step a. RAN detecting new UE and send notification to AMF b. AMF requesting NAS Identification request to UE for authentication purpose c. AMF send an authentication request to AUSF d. AUSF communicate with UDM for UE authentication data e. AUSF generate authentication key (5GAKA) and send the key to AMF f. AMF forward the key to UE g. AMF communicate with UDM to retrieve user network slice, AM subscription and SM data
