1 Introduction
The Policy Control Function (PCF) is one of the main key component of the 5G Service Based Architecture. The PCF provides the following session management related functionality:
- Policy and charging control for a service data flows
- Protocol Data Unit (PDU) Session related policy control
- PDU Session event reporting to Application Function (AF)
The PCF interacts with Access and Mobility Management Function (AMF), Session Management Function (SMF), and AF to provide policy control rules to the Network Functions (NFs) and also interacts with User Data Repository (UDR) to get the subscriber related information for creating the rules.
The PCF supports the above functions through the following services:
- Session Management Service
- Access and Mobility Service
- Policy Authorization Service
- User Equipment (UE) Policy Service
For more information about the PCF supported services, see Oracle Communications Cloud Native Policy Control Function User's Guide.
