Question: In the context of Enhanced Provisioning Paging Policy Indicator (EPPPI) for NG-RAN paging, what is the primary purpose of including DSCP to PPI Control Information in the PFCP Session Establishment/Modification Request message by the SMF?
Option 1: To instruct the UPF to prioritize uplink GTP-U packets based on QoS requirements.
Option 2: To enable the UPF to insert a Paging Policy Indicator (PPI) into downlink GTP-U packets for efficient paging, based on DSCP mapping.
Option 3: To request the UPF to modify the GTP-U PDU Session Container for all incoming UE requests.
Option 4: To notify the UPF of changes in the SMF's support for EPPPI during a PFCP session.
Explanation: The correct answer highlights the main objective of including DSCP to PPI Control Information in the PFCP message, facilitating efficient NG-RAN paging by allowing the UPF to insert a PPI into downlink GTP-U packets based on matching DSCP codes, reducing the number of PDRs/QERs needed for provisioning and enhancing the paging process's efficiency.
