Usage Reporting for Online and Offline Charging
Usage Reporting for Online and Offline Charging is supported in the following ways:
-
URR for online charging based on Rating-Group level even if the Service ID is present under Charging-Action. This behavior is seen when diameter ignore-service-id is configured under Credit Control Group.
-
URR for offline charging based on a combination of Rating-Group level and Service ID, for static and predefined rules, as configured in the Charging-Action.
Both URRs are linked by the SMF. These URRs are linked such that when an online URR is reported, an offline URR is also reported.
