PCC (Policy and Charging Control) in Mobile Networks
PCC refers to "Policy and Charging Control". It is a framework that enables mobile network operators to ensure consistent Quality of Service (QoS) for various services and applications, and implement online charging and offline charging to mobile network users.
PCC can dynamically apply policies and charging rules based on subscriber profiles, service requirements, and network conditions.
The key components of the PCC framework in mobile networks are,
- PCRF (Policy and Charging Rules Function).
- PCEF (Policy and Charging Enforcement Function).
- Online Charging System (OCS).
- Offline Charging System (OFCS).
- Other Application Functions (AF), such as the P-CSCF in IMS Network.

What is an ‘EPS Bearer’ in LTE ?
During 'LTE attach' procedure, the network establishes this EPS Bearer between the UE and the PGW. The PGW assigns an IP address for this Bearer. The UE uses this IP address, in order to communicate with the PDN. In addition, the PGW assigns a QoS for this Bearer, which guarantees the QoS for the data…
