5.8.5.11 Session Reporting Rule

Taught in 13. Where the packets actually go (The 5G system architecture, in depth), 5. The connection, and what is promised on it (The 5G system architecture, overview).

The following table describes the Session Reporting Rule (SRR) that defines the detection and reporting events that the UPF shall report, that are not related to specific PDRs of the PDU Session, as follows:

  • Per QoS Flow per UE QoS Monitoring Report, as specified in clause 5.8.2.18.
  • Change of 3GPP or non-3GPP access availability, for an MA PDU session.
  • Per QoS Flow N6 Traffic Parameter Measurement Report.

Table 5.8.5.11-1: Attributes within Session Reporting Rule

AttributeDescriptionComment
N4 Session IDIdentifies the N4 session associated to this SRR.
Rule IDUnique identifier to identify this information.Used by UPF when reporting.
QoS Monitoring per QoS Flow Control InformationIndicates the UPF to perform the QoS Monitoring for one or more QoS Flows.The IE is defined in clause 7.5.2.9 of the TS 29.244 [65].See NOTE 1.
Access Availability Control InformationIndicates the UPF to report when an access type becomes available or unavailable for an MA PDU Session.The IE is defined in clause 7.5.2.9 of TS 29.244 [65].
N6 Traffic Parameter Measurement Control InformationIndicates the UPF to report N6 Traffic parameter measurements for one QoS Flow, e.g. a measurement of N6 jitter range for a DL Periodicity and conditionally, a measurement of the UL/DL periodicity.May indicate the DL Periodicity (See NOTE 2).The IE is defined in clause 7.5.2.9 of TS 29.244 [65].See NOTE 2.
NOTE 1: The QoS Monitoring per QoS Flow Control Information may contain a Notification Target Address (the details are described in clause 5.8.2.18) that identifies the recipient of the information being notified by the UPF (Local NEF/AF) via Nupf_EventExposure_Notify service operation.NOTE 2: The DL Periodicity is provided by the SMF in the N6 Traffic Parameters Measurement Control Information when the DL Periodicity is received from the PCF.
