Abstract
Apparatuses, methods, and systems are disclosed for determining a RAT for an untrusted access network. One apparatus includes a processor and a transceiver that communicates with a first access network. The processor obtains ANI about the first access network, the ANI including an access technology type for the first access network. The processor determines to register with a mobile communication network (e.g., a 5GC) via the first access network using an untrusted registration procedure and sends a first request (e.g., an IKE_AUTH Request) to establish a secure connection with a N3IWF in the mobile communication network. Here, the first request includes a registration request for the mobile communication network and the obtained ANI, wherein the obtained ANI is used by the mobile communication network to determine a RAT for the first access network. Via the transceiver, the processor receives a response to the registration request after establishing the secure connection with the N3IWF, wherein the response depends on the RAT.
