Question: What information does a 5GSM entity in a UE acting as a 5G ProSe layer-3 UE-to-network relay UE indicate to the upper layers when establishing a new PDU session?
Option 1: Only the PDU session identity
Option 2: The SSC mode and S-NSSAI only
Option 3: Attributes such as PDU session identity, SSC mode, S-NSSAI, DNN, PDU session type, access type, and PDU address
Option 4: No information is indicated to the upper layers
Explanation: When establishing a new PDU session, the 5GSM entity in the UE acting as a 5G ProSe layer-3 UE-to-network relay UE indicates multiple attributes to the upper layers. These attributes include the PDU session identity, SSC mode, S-NSSAI, DNN, PDU session type, access type, and PDU address. This information is necessary for the proper setup and management of the PDU session in the 5G network.
