PCC – Policy and Charging Control

3GPP System Overview

• GPRS/UMTS network architectures and mode of operation
• EPS (Evolved Packet System) – architecture and mode of operation
• PDNs (Packet Data Networks)
• QoS handling

PCC Introduction and Architecture

• IP Connectivity access networks (IP-CANs)
• PCC high level principles
• PCC nodes/functions (PCRF, SPR, AF and PCEF)
• Protocols and Reference points used for PCC
• Sessions, Bearers and Service Data Flows (SDF)

The Diameter protocol

• The Diameter protocol
• Commands and and Attribute Value Pairs
• Diameter routing principles
• PCC Diameter use case

Policy Control part 1

• What does Policy Control include?
• Role of PCRF, PCEF, TDF, AF, OCS and SPR
• Generation of PCC rules
• Contents of PCC rules – SDF description, Charging and QoS parameters
• ADC – Application Detection and Control
• Signalling flows on Gx, Rx, Sd and Sy

Policy Control part 2

• User plane handling in PCEF
• QoS authorization and control for Service Data Flows and IP-CAN Bearers
• Gating and Redirect
• Event reporting and Usage Monitoring
• Relevant signalling flows
• Roaming scenarios with local breakout or home routed access
• Home PCRF and Visited PCRF
• Interaction on the S9 interface for roaming scenarios

Online Charging

• Online Credit Control
• Flow Based Charging (FBC) activities
• The Gy/Ro reference point
• Usage and Event reporting
• Diameter for Online Charging

Offline Charging

• Offline Charging principles
• Flow Based Charging (FBC) activities
• Usage reporting and Event reporting
• Relevant signalling flows
• Protocols ( Diameter, GTP’ and FTP)
• Reference points (Gz, Ga, Rf)
• CDR content
