Feature Overview
This non-standard Time Usage Reporting over Gx feature is similar to Volume Usage Reporting over Gx. PCRF
provides the time usage threshold for entire session or particular monitoring key in CCA or RAR. When the given
threshold breached usage report will be sent to PCRF in CCR. This time threshold is independent of data traffic. Apart
from the usage threshold breach there are other scenarios where usage report will be send to PCRF.

reason, the rules associated with the bearer will also be removed. So, the usage will be reported on the monitoring key(s)
whose associated rule is the last one that is removed because of bearer termination.
The following steps explain how Time Reporting over Gx works:
1. PCEF after receiving the message from PCRF parses the time monitoring related AVPs, and sends the
information to IMSA.
2. IMSA updates the information to ECS.
3. Once the ECS is updated with the time monitoring information from PCRF, the PCEF (ECS) starts tracking the
time usage.
4. For session-level monitoring, the ECS maintains the amount of time usage.
5. For PCC rule monitoring, usage is monitored with the monitoring key as the unique identifier. Each node
maintains the time usage information per monitoring key.
Time reporting over Gx is applicable only for time quota.
The PCEF only reports the accumulated time usage since the last report for time monitoring and not
If the time usage threshold is set to zero (infinite threshold), no further threshold events will be
