Question: What information does the AMF include in the NETWORK SLICE-SPECIFIC AUTHENTICATION RESULT message when initiating the network slice-specific EAP result message transport procedure?
Option 1: Only the EAP-success or EAP-failure message provided by the AAA-S via the NSSAAF.
Option 2: The EAP message IE set to the EAP-success or EAP-failure message and the S-NSSAI IE set to the HPLMN S-NSSAI or the SNPN S-NSSAI.
Option 3: The UE's registration status and the PLMN identifier.
Option 4: The authentication result for the UE and the HPLMN S-NSSAI or the SNPN S-NSSAI.
Explanation: According to the 3GPP specification, when initiating the network slice-specific EAP result message transport procedure, the AMF includes both the EAP-success or EAP-failure message and the HPLMN S-NSSAI or the SNPN S-NSSAI in the NETWORK SLICE-SPECIFIC AUTHENTICATION RESULT message. This ensures that the UE receives the necessary information to complete the authentication and authorization process.
