  • EMERGENCY CALL HANDLING IN CELLULAR NETWORKS AFTER FAILED AUTHENTICATION
    Publication number: 20160007176
    Abstract: A mobile device may place an emergency call via a wireless cellular network. The mobile device receives an initiation of the emergency call and determines whether a first base station to which it is attempting to connect is authenticated. Authentication of the first base station is determined based on a state of an authentication timer of the mobile device. If authentication of the first base station fails, the mobile device establishes a connection to a second base station and places the emergency call via the connection with the second base station.
