Usage Reporting
UPF measures the volume and the time usage of all traffic for the PDU session or the corresponding service data flows. UPF sends the accumulated usage report in either the PFCP Session Report Request or the PFCP Session Modification Response to SMF. SMF includes one or multiple accumulated usage reports in the "accuUsageReports" attribute towards PCF.
Note | The Usage Monitoring over PCF feature is enabled from SMF. |
NOTE: To know more about how SMF handles this functionality, refer to the Usage Monitoring over PCF section in the Policy and User Plane Management chapter of UCC 5G SMF Configuration and Administration Guide.
