There are several important NAS signaling messages related to 5G Authentication. In this section, I will summarize about a few most important messages and look into its structure. The "Authentication Request" message is used by the mobile device to initiate the registration process with the 5G core network.
The Base Station CU uses the NGAP: Initial Context Setup Request to generate the FIAP: UE Context Setup Request which is then forwarded to the DU. This FI AP message requests the DU to setup resources for both SRB 2 and the set of DRB required by the PDU Sessions listed within the NGAP message.
The "Authentication Request" message is used by the mobile device to initiate the registration process with the 5G core network. The Authentication Request message contains important information about the mobile device, and is sent to the 5G core network via the Radio Access Network (RAN) and conveyed to AMF.
The AMF is responsible for managing user access to the 5G core network. It is the first point of contact for the User Equipment (UE) and initiates the authentication process. The AMF receives the initial authentication information from the UE and forwards it to the AUSF for verification. The AUSF verifies the credentials provided by the UE.
