Original Abstract Submitted
this application sets forth techniques for authenticating a mobile device with a cellular wireless network without electronic subscriber identity module (esim) credentials by using an extensible authentication protocol transport layer security (eap-tls) procedure. the mobile device authenticates with an authentication server function (ausf) of the cellular wireless network using an embedded universal integrated circuit card (euicc) certificate. processing circuitry of the mobile wireless device external to the euicc implements the eap-tls procedure and authenticates validity of the ausf. in some embodiments, the euicc provides key generation and storage for a session key for communication between the mobile device and the cellular wireless network. in some embodiments, a third-party managed unified data management (udm) broker authenticates the mobile device based on knowledge of the euicc certificate and provides a session key to the cellular wireless network for subsequent communication with the mobile device, upon successful authentication of the mobile device.
