Section: 5.20d User Plane Direct 5GS Information Exposure 5.20d.1 General
Content: In order to expose network information, the user plane direct 5GS information exposure function may be applied. The user plane direct 5GS information exposure function allows the UPF to report the network information directly to consumer based on the instructions provided by SMF. NOTE: In the scenario of Edge Computing as described in TS 23.548[ 5G System Enhancements for Edge Computing; Stage 2 ]  [130], the consumer can be the L-NEF or local AF when the local AF is trusted. When the exposed network information is provided by the UPF, the PSA UPF may be instructed to report network information via Nupf_EventExposure service (e.g. directly to an AF, i.e. bypassing the SMF and the PCF); or the UPF may be instructed to report the information to the consumer via SMF/PCF/NEF, as described in clause 5.8.2.18. When the exposed network information is provided by the NG-RAN, the NG-RAN may be instructed by the SMF to report the information via the GTP-U tunnel(s) between the NG RAN and PSA UPF, as defined in clause 5.45. The User Plane Direct 5GS Information Exposure may be used for exposing the following information: - QoS Monitoring information (see clause 5.45). - TSC Management Information (see clause 5.28.3).
