Figure 8.2.41-1: Usage Report Trigger
Octet 5 shall be encoded as follows:
– Bit 1 – PERIO (Periodic Reporting): when set to "1", this indicates a periodic report.
– Bit 2 – VOLTH (Volume Threshold): when set to "1", this indicates that the data volume usage reaches a volume threshold.
– Bit 3 – TIMTH (Time Threshold): when set to "1", this indicates that the time usage reaches a time threshold.
– Bit 4 – QUHTI (Quota Holding Time): when set to "1", this indicates that no packets have been received for a period exceeding the Quota Holding Time.
– Bit 5 – START (Start of Traffic): when set to "1", this indicates that the start of traffic is detected.
– Bit 6 – STOPT (Stop of Traffic): when set to "1", this indicates that the stop of traffic is detected.
– Bit 7 – DROTH (Dropped DL Traffic Threshold): when set to "1", this indicates that the DL traffic being dropped reaches a threshold.
– Bit 8 – IMMER (Immediate Report): when set to "1", this indicates an immediate report reported on CP function demand.
Octet 6 shall be encoded as follows:
– Bit 1 – VOLQU (Volume Quota): when set to "1", this indicates that the Volume Quota has been exhausted.
– Bit 2 – TIMQU (Time Quota): when set to "1", this indicates that the Time Quota has been exhausted.
– Bit 3 – LIUSA (Linked Usage Reporting): when set to "1", this indicates a linked usage report, i.e. a usage report being reported for a URR due to a usage report being also reported for a linked URR (see clause 5.2.2.4).
– Bit 4 – TERMR (Termination Report): when set to "1", this indicates a usage report being reported (in a PFCP Session Deletion Response) for a URR due to the termination of the PFCP session, or a usage report being reported (in a PFCP Session Modification Response) for a URR due to the removal of the URR or dissociated from the last PDR.
– Bit 5 – MONIT (Monitoring Time): when set to "1", this indicates a usage report being reported for a URR due to the Monitoring Time being reached.
– Bit 6 – ENVCL (Envelope Closure): when set to "1", this indicates the usage report is generated for closure of an envelope (see clause 5.2.2.3).
– Bit 7 – MACAR (MAC Addresses Reporting): when set to "1", this indicates a usage report to report MAC (Ethernet) addresses used as source address of frames sent UL by the UE.
– Bits 8: EVETH (Event Threshold): when set to "1", this indicates a usage report is generated when an event threshold is reached.
Octet 7 shall be encoded as follows:
– Bit 1 – EVEQU (Event Quota): when set to "1", this indicates that the Event Quota has been exhausted.
– Bit 2 – TEBUR (Termination By UP function Report): when set to "1", this indicates a usage report being reported for a URR due to the termination of the PFCP session which is initiated by the UP function.
– Bit 3 – IPMJL (IP Multicast Join/Leave): when set to "1", this indicates a usage report being reported for a URR due to the UPF adding or removing the PDU session to/from the DL replication tree associated with an IP multicast flow.
– Bit 4 – QUVTI (Quota Validity Time): when set to "1", this indicates a usage report being reported for a URR due to the quota validity timer expiry.
– Bit 5 – EMRRE (End Marker Reception REport): this indicates that the UP function has received End Marker from the old I-UPF. See clauses 4.2.3.2 and 4.23.4.3 in 3GPP TS 23.502 [29]).
– Bit 6 – UPINT (User Plane Inactivity Timer): when set to "1", this indicates that no packets have been received for a period exceeding the User Plane Inactivity Timer.
– Bit 7 to 8: Spare, for future use and set to "0".
At least one bit shall be set to "1". Several bits may be set to "1".
