Section: 5.4.7.2.2 Network slice-specific EAP message reliable transport procedure accepted by the UE
Content: When the upper layers provide an EAP-response message associated with the HPLMN S-NSSAI or the SNPN S-NSSAI, the UE shall create a NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message. The UE shall set the EAP message IE of the NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message to the EAP-response message. The UE shall set the S-NSSAI IE of the NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message to the HPLMN S-NSSAI or the SNPN S-NSSAI associated with the EAP-response message. The UE shall send the NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message. Apart from this action, the network slice-specific authentication and authorization procedure is transparent to the 5GMM layer of the UE. Upon receipt of a NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message, the AMF shall stop timer T3575 and: a) pass the EAP-response message received in the EAP message IE of the NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message associated with the HPLMN S-NSSAI or the SNPN S-NSSAI in the S-NSSAI IE to the upper layers; or b) provide the EAP-response message received in the EAP message IE of the NETWORK SLICE-SPECIFIC AUTHENTICATION COMPLETE message associated with the HPLMN S-NSSAI or the SNPN S-NSSAI in the S-NSSAI IE to the AAA-S via the NSSAAF.
