5.8.5.12 Session reporting generated by UPF
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 UPF sends the session report to inform the SMF the detected events for a PDU Session that are related to an SRR. The UPF may support notification to the AF possibly via local NEF as described in clause 6.4 of TS 23.548 [130].
