Usage Reporting with Rating-Group and Service ID

The functionality enables usage reporting to the SMF with the Rating-Group (RG) and/or Service ID (SI) populated in the Usage Report IE within the Session Report Request.

The RG and SI are populated using proprietary PFCP IEs and are applicable for usage reporting of URRs associated only with Static and Predefined configured rules. The values are derived from the configured charging-action associated with the ruledefs, resulting in creation of the URRs during predefined activation or traffic hit for static rules.

Any change in RG/SI properties of the charging-action is reflected only in new URRs. The existing URRs associated with such charging-actions continue to report usage with the earlier RG+SI values.

UPF does not differentiate between usage reporting for Online and Offline URRs, and reports the RG+SI/RG/SI values configured in the charging-action, resulting in creation of the URRs.

NOTE: To know how SMF handles this functionality, refer Dynamic Configuration Change Support section in the SMF Charging chapter of UCC 5G SMF Configuration and Administration Guide.
