Section: 5.8.5.7 Usage Report generated by UPF
Content: The UPF sends the Usage Report to inform the SMF about the measurement of an active URR or about the detection of application traffic of an active Packet Detection Rule. For each URR, the Usage Report may be generated repeatedly, i.e. as long as any one of the valid event triggers applies. A final Usage Report is sent for a URR when it is no longer active, i.e. either the URR is removed or all the references to this URR in any of the Packet Detection Rules belonging to the N4 session. The following attributes can be included: Table 5.8.5.7-1: Attributes within Usage Report
