Abstract

Communications are established with a first base station and the communications include first validation information associated with the first base station. Second validation information is obtained and the second validation information is stored in a data structure. The second validation information is associated with a second and valid base station. The first validation information is compared to the second validation information stored in the data structure and it is determined whether the first base station is valid based upon the comparison. When the comparing indicates that the first base station is not valid, a warning is initiated to a user.

Claims

1. A method of detecting a cloned base station:

establishing communications with a first base station, the communications including first validation information associated with the first base station;

obtaining second validation information and storing the second validation information in a data structure, the second validation information being associated with a second and valid base station;

comparing the first validation information to the second validation information stored in the data structure and determining whether the first base station is valid based upon the comparing;

when the comparing indicates that the first base station is not valid, initiating a warning to a user.

2. The method of claim 1 further comprising scanning for a presence of a neighboring base station identified in the data structure and when a signal strength level of the neighboring base station obtained by the scanning is below a predetermined threshold level, initiating a warning to the user that a cloned base station has been detected.

3. The method of claim 1 further comprising building the data structure in memory, the data structure comprising information obtained from an external source upon a successful communication with a known and valid service provider.

4. The method of claim 3 wherein the information is downloaded from the known and valid service provider to build the data structure.

5. The method of claim 3 wherein information is downloaded from the known and valid service provider periodically.

6. The method of claim 3 wherein information is downloaded asynchronously to the data structure.

7. The method of claim 1 further comprising establishing a communication link with a back end device and responsively adding data to the data structure when the establishing is successful.

8. A computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method of detecting a cloned base station from a vehicle, the method comprising:

establishing communications between the vehicle and a first base station, the communications including first validation information associated with the first base station;

obtaining second validation information and storing the second validation information in a data structure at the vehicle, the second validation information being associated with a second and valid base station;

comparing the first validation information to the second validation information stored in the data structure and determining whether the first base station is valid based upon the comparing;

when the comparing indicates that the first base station is not valid, initiating a warning to a user at the vehicle.

9. The computer usable medium of claim 8 further comprising scanning for a presence of a neighboring base station identified in the data structure and when a signal strength level of the neighboring base station obtained by the scanning is below a predetermined threshold level, initiating a warning to the user that a cloned base station has been detected.

10. The computer usable medium of claim 8 further comprising building the data structure in memory at the vehicle, the data structure comprising information obtained from an external source upon a successful communication with a known and valid service provider.

11. The computer usable medium of claim 10 wherein the information is downloaded to the vehicle from the known and valid service provider to build the data structure.

12. The computer usable medium of claim 10 wherein information is downloaded to the vehicle from the known and valid service provider periodically.

13. The computer usable medium of claim 10 wherein information is downloaded asynchronously to the data structure at the vehicle.

14. An apparatus for detecting a cloned base station:

a communication interface configured to establish communications with a first base station, the communications including first validation information associated with the first base station;

a memory comprising a data structure;

a warning indicator;

a controller coupled to the communication interface, the memory, and the warning indicator, the controller configured to obtain second validation information via the communication interface and store the second validation information in the data structure in the memory, the second validation information being associated with a second and valid base station, the controller being further configured to compare the first validation information to the second validation information stored in the data structure and determine whether the first base station is valid based upon the comparison, the controller being further configured to, when the comparing indicates that the first base station is not valid, initiate a warning to a user via the warning indicator.

15. The apparatus of claim 14 wherein the controller is further configured to scan for a presence of a neighboring base station identified in the data structure via the communication interface and when a signal strength level of the neighboring base station obtained by the scanning is below a predetermined threshold level, initiate a warning to the user via the warning indicator that a cloned base station has been detected.

16. The apparatus of claim 14 wherein the controller is further configured to build the data structure in memory, the data structure comprising information obtained from an external source upon a successful communication with a known and valid service provider.

17. The apparatus of claim 16 wherein the information is downloaded from the known and valid service provider to build the data structure.

18. The apparatus of claim 16 wherein information is downloaded from the known and valid service provider periodically.

19. The apparatus of claim 16 wherein the warning indicator is selected from the group consisting of an audio speaker, flashing vehicular lights, and a honking horn.

20. The apparatus of claim 14 wherein the warning indicator is configured to be actuated before a user exits the vehicle.
