Abstract
A signal on a wireless communication system control channel can be identified as authentic or malicious by monitoring control channel signal strength changes. When a control channel signal level increases abnormally, a geographic location is obtained from a navigation system, such as a GPS. The determined location is compared to locations in a data base of locations where control channel jamming transmitters are known to exist, and/or likely to exist. If the then-current location is not in the data base, the detected control channel signal level increase is considered to be malicious, i.e., from a jamming transmitter, often used by car thieves.
