Methods and systems for base station detection
First Claim
1. A method for detecting an unauthorized base station, comprising:
- scanning, by an in-vehicle controller of a vehicle or an application of a mobile communications device, a cellular radio environment to identify an available base station;
detecting, by a signal detection unit in operative communication with the in-vehicle controller or the application, a strength of a signal of the available base station;
comparing the detected signal strength with an expected signal strength range;
determining that the detected signal strength is out of the expected signal strength range;
categorizing the available base station as an unauthorized base station;
connecting to the unauthorized base station;
while in connection with the unauthorized base station, determining, by the in-vehicle controller or the application, a location of the unauthorized base station by triangulating a location of the vehicle or the mobile communications device, a direction of the signal, and the signal strength; and
transmitting invalid signal strength information to the unauthorized base station to entice the unauthorized base station to further reduce the signal strength out of the expected signal strength range, wherein the invalid signal strength information falsely informs the unauthorized base station that its emitted signal is higher than a power level of the signal actually transmitted by the unauthorized base station.

Abstract
Methods and systems for unauthorized base station detection are disclosed herein. In an example of the method, an in-vehicle controller of a vehicle or an application of a mobile communications device scans a cellular radio environment to identify an available base station. By a signal detection unit in operative communication with the in-vehicle controller or the application, a strength of a signal of the available base station is detected. The in-vehicle controller or the application recognizes that the signal strength is out of the expected signal strength range, and determines that the available base station is the unauthorized base station. While in connection with the unauthorized base station, the in-vehicle controller or the application determines a location of the unauthorized base station. Other examples of the method are also disclosed herein.

9. A system for detection of a base station categorized as unauthorized, comprising:
-
an in-vehicle controller of a vehicle or an application of a mobile communications device; computer-readable instructions for scanning a cellular radio environment to identify an available base station; a signal detection unit in operative communication with the in-vehicle controller or the application, the signal detection unit including a receiver to detect a strength of a signal of the available base station; computer-readable instructions for recognizing that the signal strength of the available base station is out of an expected signal strength range and to determine that the available base station is the unauthorized base station; wireless communication equipment to connect the in-vehicle controller or the mobile communications device to the unauthorized base station; computer-readable instructions for determining a location of the unauthorized base station by triangulating a location of the vehicle or the mobile communications device, a direction of the signal, and the signal strength while the in-vehicle controller or the mobile communications device is in connection with the unauthorized base station; and computer-readable instructions for transmitting invalid signal strength information to the unauthorized base station to entice the unauthorized base station to further reduce the signal strength out of the expected signal strength range, wherein the invalid signal strength information falsely informs the unauthorized base station that its emitted signal is higher than a power level of the signal actually transmitted by the unauthorized base station; each of the computer-readable instructions being embodied on a non-transitory, tangible computer readable medium and executable by a processor of the in-vehicle controller or a processor of the mobile communications device. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for detecting an unauthorized base station, comprising:
-
scanning, by an in-vehicle controller of a vehicle, a cellular radio environment to identify an available base station; detecting, by a signal detection unit in operative communication with the in-vehicle controller, a strength of a signal of the available base station; comparing the detected signal strength with an expected signal strength range;
determining that the detected signal strength is out of the expected signal strength range;categorizing the available base station as an unauthorized base station; connecting to the unauthorized base station; and
while in connection with the unauthorized base station, determining, by the in-vehicle controller, a location of the unauthorized base station using a location of the vehicle,transmitting invalid signal strength information to the unauthorized base station to entice the unauthorized base station to further reduce the signal strength out of the expected signal strength range, wherein the invalid signal strength information falsely informs the unauthorized base station that its emitted signal is higher than a power level of the signal actually transmitted by the unauthorized base station.
