3GPP R9 Volume Charging Over Gx

Also known as accumulated usage tracking over Gx, this 3GPP R9 enhancement provides a subset of the volume and
charging control functions defined in TS 29.212 based on usage quotas between a P-GW and PCRF. The quotas can be
assigned to the default bearer or any of the dedicated bearers for the PDN connection.
This feature enables volume reporting over Gx, which entails usage monitoring and reporting of the accumulated usage
of network resources on an IP-CAN session or service data flow basis. PCRF subscribes to the usage monitoring at
session level or at flow level by providing the necessary information to PCEF. PCEF in turn reports the usage to the
PCRF when the conditions are met. Based on the total network usage in real-time, the PCRF will have the information
to enforce dynamic policy decisions.
When usage monitoring is enabled, the PCEF can monitor the usage volume for the IP-CAN session, or applicable
service data flows, and report accumulated usage to the PCRF based on any of the following conditions:
 When a usage threshold is reached,
 When all PCC rules for which usage monitoring is enabled for a particular usage monitoring key are removed or
deactivated,
 When usage monitoring is explicitly disabled by the PCRF,
 When an IP CAN session is terminated or,
 When requested by the PCRF.
To configure the basic service and functionality on the system for the P-GW service, refer to the
