EMERGENCY CALL HANDLING IN CELLULAR NETWORKS AFTER FAILED AUTHENTICATION |
| 摘要 |
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. |

1. A method for causing a mobile apparatus to place an emergency call in a wireless cellular network, comprising:
receiving, in a processing circuit of the mobile apparatus, initiation of the emergency call; determining an authentication of a first base station corresponding to a first cell based on an authentication timer of the mobile apparatus; establishing a communication connection to a second base station corresponding to a second cell when the authentication timer indicates an authentication failure of the first base station; and placing the emergency call via the communication connection to the second base station. |
