Abstract: 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.

Abstract: Disclosed is a road projecting method and system for a traffic light. A passable region and an impassable region are determined according to a current state and a time period of the traffic light and a preset travelling speed of a vehicle; on a map, the passable region is displayed in a first manner, and the impassable region is displayed in a second manner; and the first manner is different from the second manner. The road projecting method and system for a traffic light provided by the present invention divides the road on which the vehicle is running into the passable region and the impassable region on the map, and the passable region and the impassable region are displayed in different manners, thereby avoiding congestion caused by stop of a large number of vehicles close to the intersection and improving the traffic efficiency.
