Question: In a Home Routed PDU Session scenario, what type of NAS SM information is not visible to the V-SMF and only processed by the H-SMF?
Option 1: Indication of the nature of the NAS SM signalling (e.g., PDU Session Establishment Request), PDU Session Type
Option 2: SSC mode, Protocol Configuration Options, SM PDU DN Request Container, QoS Rule(s) and QoS Flow level QoS parameters if any for the QoS Flow(s) associated with the QoS rule(s)
Option 3: UE addressing information (allocated IPv4 address, interface identifier), Session-AMBR
Option 4: PDU Session ID, DNN, S-NSSAI
Explanation: According to clause 5.6.3 of TS 23.501, in a Home Routed PDU Session scenario, the H-SMF processes NAS SM information that is not visible to the V-SMF, which includes SSC mode, Protocol Configuration Options, SM PDU DN Request Container, QoS Rule(s) and QoS Flow level QoS parameters if any for the QoS Flow(s) associated with the QoS rule(s).
