Abstract: Apparatuses, methods, and systems are disclosed for network slice authentication. One apparatus includes a processor that provides an application layer and a non-access stratum (“NAS”) layer and a transceiver for communicating with a mobile communication network. The processor receives, at an application at the application layer, network slice authentication information for a subscribed service and stores the network slice authentication information at an application module. The processor associates the network slice authentication information with single network slice selection assistance information (“S-NSSAI”) and registers the application with the NAS layer, said registration pointing to the associated S-NSSAI. Additionally, the transceiver that exchanges, via the NAS layer, authentication messages with an authentication, authorization, and accounting (“AAA”) server for network slice authentication information.
