Abstract  Abstract

Apparatuses, methods, and systems are disclosed for determining a RAT for an untrusted access network. One apparatus (400) includes a processor (405) and a transceiver (425) that communicates with a first access network. The processor (405) obtains (605) ANI about the first access network, the ANI including an access technology type for the first access network. The processor (405) determines (610) to register with a mobile communication network (e.g., a 5GC) via the first access network using an untrusted registration procedure and sends (615) 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 (625), the processor (605) receives (620) a response to the registration request after establishing the secure connection with the N3IWF, wherein the response depends on the RAT.
