PCC typically stands for Policy and Charging Control in the context of 4G and 5G networks. It's a key element in the Evolved Packet Core (EPC) for 4G LTE networks and the 5G Core (5GC) for 5G networks. PCC plays a crucial role in managing network resources, enforcing policies, and handling charging aspects.

Policy and Charging Control (PCC) in 5G involves several components and functions. Let's break down some key aspects:

  1. Policy Control Function (PCF): PCF is responsible for the policy control decision-making in the 5G network. It determines and enforces policies related to Quality of Service (QoS), access control, and flow control. PCF interacts with other network functions to convey policy decisions.
  2. Unified Data Management (UDM): UDM is responsible for managing subscription-related data, such as user profiles, authentication data, and policy data. It provides information to the PCF for making policy decisions.
  3. User Plane Function (UPF): The UPF handles user data forwarding, including packet routing, forwarding, and anchoring. It is responsible for ensuring the data flows according to the established policies and QoS parameters.
  4. Session Management Function (SMF): SMF is responsible for setting up, modifying, and releasing sessions. It interacts with the PCF to enforce policies related to session management.
  5. Charging Function (CHF): The CHF is responsible for handling charging and billing-related functions. It collects information about the data usage and resources consumed by users and provides this information to the charging system.
  6. Authentication Server Function (AUSF): AUSF handles authentication-related functions. It authenticates users and provides authentication information to other network functions.
  7. Network Exposure Function (NEF): NEF provides a standardized interface for exposing network capabilities and services. It allows external applications and services to interact with the 5G network for various purposes.

Policy and Charging Control (PCC) in 5G involves various network functions working together to enforce policies, manage user sessions, handle charging aspects, and ensure a smooth flow of data in the network. Each component plays a specific role in providing a robust and efficient communication environment in the 5G network.
