Converged Policy Control Function
What is PCF in 5G?
The PCF in 5G serves as a unified platform to govern the implementation of policy control and charging rules. It enables end-to-end policy management based on network parameters, implements slice-based policies for applications, supports innovation and enrichment through service exposure, and offers advanced analytics for improved services.
How does 5G PCF work?
The 5G PCF uses the policy subscription information store in the User Data Repository (UDR) to provide policy rules to network functions (SMF/AMF). It uses a standard REST-based interface to integrate with AMF for access and mobility policy, and SMF for session management policy. The Converged Policy Control Function supports rule configuration based on subscription information and network parameters and provides policies for data, voice, and application services in 4G and 5G networks.
