Abstract
Apparatuses, methods, and systems are disclosed for supporting TNGF reauthentication. One apparatus includes a network interface that communicates with a remote unit (i.e., UE) and with a mobile communication network. The apparatus includes a processor that receives a first EAP message containing a NAI from the UE. Here, the NAI indicates that the UE requests to reauthenticate with a source gateway function. The processor receives a UE context of the UE and derives a first EAP challenge packet using the UE context. Via the network interface, the processor sends the first EAP challenge packet to the UE. Here, the first EAP challenge packet is used to authenticate the target TNGF with the UE.
