Paging Policy Differentiation
The UPF supports the Paging Policy Differentiation, for each PDR and for each packet that triggers a Downlink Data Notification, the UPF function copies the value of the DSCP in TOS (IPv4) or TC (IPv6) information received in the IP payload in Downlink Data Service Information IE.
For each PDR and for each packet that triggers a Downlink Data Notification, if the QFI of the downlink data packet is available, the QFI is also sent in Downlink Data Service Information IE.
