name: AUN3
full_form: Authenticable Non-3GPP devices
context: AUN3 device indicator. 4c. If the RG is a 5G-RG, the 5G-RG constructs a SUCI from the NAI-based SUPI of the AUN3 device, and sends a NAS Registration Request message to the AMF, including the SUCI and an AUN3 device indicator. 5. The AMF/SEAF selects the AUSF based on the SUCI in the received registration request and sends a Nausf_UEAuthentication_Authenticate Request message to the AUSF. It contains the SUCI of the AUN3 device, and an AUN3 device indicator. 6. The AUSF sends a Nudm_UEAuthentication_Get Request to the UDM. It contains the SUCI of the AUN3 device and the AUN3 device indicator. 7. The UDM invokes the SIDF to map the SUCI to the SUPI and selects an authentication method based on the SUPI. When the "username" part of the SUPI is "anonymous" or omitted, the UDM may select an authentication method based on the ârealmâ part of the SUPI, the AUN3 device indicator, a combination of the "realm" part and the AUN3 device indicator, or the UDM local policy. 8. The UDM sends a
description: AUN3 refers to Authenticable Non-3GPP devices, which are user equipment (UE) that do not use 3GPP access technologies but can still be authenticated and authorized for network services. These devices may use alternative access methods such as Wi-Fi or fixed broadband connections.
explanation: The context explicitly states 'AUN3 device', classifying it as a type of device.  Furthermore, its role in authentication processes within the network further supports this classification.
