PCRF Training Description, Policy and Charging Rules Function Training

PCRF Training covers all aspects of Policy Control and Charging (PCC) functionality including: Policy and Charging Rules Function (PCRF), Policy and Charging Enforcement Function (PCEF), Bearer Binding and Event Reporting Function (BBERF), Online Charging System (OCS), Offline Charging System (OFCS), Subscription Profile Repository (SPR) and Application Function (AF).

PCC enables a centralized control to ensure that the service sessions or  IP-CAN sessions, are provided with appropriate bandwidth and QoS. PCC also provides a means to control charging on a per-service basis.

Policy and Charging Rules Function (PCRF) is part of the PCC and supports service data flow detection, policy enforcement, flow-based charging. PCRF manages policies to manage and control Quality of Service (QoS), charging, quota, optimization and admission control.

Policy and Charging Control functionality encompasses two main including Flow Based Charging, charging control and online credit control, and Policy control such as gating control, QoS control, and QoS signalling.

PCRF function aspart of the larger PCC architecture,  includes the Proxy Call Session Control Function (P-CSCF) and the Policy and Charging Enforcement Function (PCEF).

Learn about PCC functions including:

  • PCRF (policy and charging rules function)
  • PCEF (policy and charging enforcement function)
  • OCS (online charging system)
  • OFCS (off-line charging system)
  • PCC rules and its purposes
  • Policy rules between applications and policy enforcement points
  • gx: Policy decisions-related information between PCEF and PCRF
  • Gy: Online flow based bearer charging PCEF and OCS 
  • Sy: Policy rules between PCRF and OCS (Online Charging System)
  • Gq: Policy exchange policy decisions-related information between P-CSCF and PDF
