Offline Bearer and SDF Level or SDF Level URR for Dynamic Rules
The following call flow and procedure describes the Usage report in N4 session report with Volume/Time threshold for the offline Bearer or SDF level, or SDF level URR for Dynamic rules.
Note | Ensure that the URR is present on the UPF with values such as Thresholds and so on. Volume/Time threshold is hit at the UPF for Bearer/SDF or SDF level URRs. UPF relays usage to the SMF along with usage reporting trigger information. |

Step | Description | ||
---|---|---|---|
1 |
UPF sends N4 Session Report Request for either offline Bearer usage along with SDFs or only SDFs usage to the SMF. |
||
2 |
SMF sends N4 Session Report Response. |
||
3 |
SMF sends GTPP Data Record Transfer Request with SDF Containers to the Offline Charging System (OFCS). This request is sent with one or multiple SDFs with volume usage and serviceConditionChange—one for each RG+service ID.
|
||
4 |
OFCS sends GTPP Data Record Transfer Response. |
