Question: How does the vNSSF identify the Home Network for routing of HTTP/2 messages across the PLMN?
Option 1: By using the IMSI of the UE
Option 2: By using the IP address of the hNSSF
Option 3: By using the PLMN ID of the SUPI provided by the NF Service Consumer (e.g. the AMF)
Option 4: By using the FQDN of the vNSSF
Explanation: The Home Network is identified by the PLMN ID of the SUPI provided to the vNSSF by the NF Service Consumer (e.g. the AMF), which allows the vNSSF to self-construct the FQDN and URI of the hNSSF for routing purposes.
