5.43.5 QoS monitoring when dynamic Satellite Backhaul is used

Taught in 26. Relays, satellites, femtos and shared networks (The 5G system architecture, in depth).

If dynamic satellite backhaul is used, QoS monitoring may be used to measure packet delay as specified in clause 5.45.2.

If the Satellite backhaul category received from SMF indicates dynamic satellite backhaul is used, the PCF may, based on PCF local policy or configuration, request QoS monitoring for the packet delay between UE and PSA UPF as specified in clause 5.45.2. The AF may trigger QoS monitoring by requesting QoS monitoring report from the PCF e.g. when the AF has received a dynamic satellite backhaul category.

NOTE: PCF handling of satellite backhaul category indication and possible QoS monitoring is specified in TS 23.503 [45].
