| 20110028149 | Method and Apparatus to Facilitate Influencing Handover Decisions - A cellular communications system end-user transceiver ( | 02-03-2011 |
| 20110148610 | Apparatus And Method For Compromised Vehicle Tracking - Before a vehicle is parked, a signal is received from at least one of a base station and a location determination system. It is determined when the signal fails to meet at least one predetermined criteria. When the signal fails to meet the at least one predetermined criteria, a warning message is formed and presented to an operator of the vehicle. | 06-23-2011 |
| 20110148712 | Apparatus And Method For Determining Vehicle Location - Communications are established and conducted between a communication and jamming detection at a vehicle and a base station. At the communication and jamming detection device, a determination is made as to when jamming of the communications between the communication and jamming detection device and the base station is occurring. When jamming is determined to be occurring, at least one location determination signal is transmitted from the communication and jamming detection device to at least one external tracking device. At the at least one external location determination device, the at least one location determination signal is received from the communication and jamming detection device. The location of the communication and jamming detection device at the vehicle is determined from the at least one location determination signal. | 06-23-2011 |
| 20110151768 | Apparatus And Method For Detecting Jamming Of Communications - Location determination signals are received and a location of interest is determined from the location determination signals. A communication service with a known, valid base station via a first communication channel is established and synchronized. A first rate of rise of a signal strength indicator associated with the first communication channel is monitored and a second rate of rise of a signal quality indicator associated with the first communication channel is also monitored. When at least one of the first rate rises at a rate greater than a first predetermined threshold rate and the second rate rises at a rate greater than a second predetermined threshold rate, a warning message is transmitted to the known, valid base station before synchronization of the communication service is lost with the known, valid base station. | 06-23-2011 |
| 20110151791 | Apparatus And Method For Maintaining Communication With A Stolen Vehicle Tracking Device - Communications are maintained between a base station and a stolen vehicle tracking (SVT) module disposed with a vehicle. At the SVT module at the vehicle, it is determined whether jamming is occurring with communications between the SVT module and the base station and a temperature is measured at the SVT module. When jamming is detected, an adjustment is determined for a frequency of an oscillator of the SVT module and the adjustment is based at least in part upon the temperature. The frequency of operation of an oscillator is adjusted according to the adjustment. A message is transmitted to the base station according to the adjusted frequency. | 06-23-2011 |
| 20110151795 | Apparatus And Method For Maintaining Communications With A Vehicle In The Presence Of Jamming - Jamming is detected as occurring to communications associated with at least one electronic device disposed at a vehicle. Responsive to detecting the jamming, an indication is transmitted from the vehicle to a base station informing the base station that jamming is occurring. Communications are subsequently conducted between the base station and the vehicle on at least one predetermined and prearranged communication channel. | 06-23-2011 |
| 20110151796 | Apparatus And Method For Detecting A Cloned Base Station - 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. | 06-23-2011 |
| 20110151799 | Apparatus And Method For Detecting Communication Interference - Location determination signals are received and a location of interest is determined from the location determination signals. A communication service is established and synchronized with a known, valid base station via a first communication channel. A value of a signal strength indicator associated with the first communication channel is monitored. When the value of the signal strength indicator falls below a threshold level, a warning message is transmitted to the known, valid base station before synchronization of the communication service is lost with the known, valid base station. | 06-23-2011 |
| 20110151827 | Apparatus And Method For Broadcasting The Detection Of RF Jammer Presence - The jamming of a radio frequency (RF) transmission after the vehicle is parked is detected. When the jamming is detected, an emergency message is broadcast on a first random access channel (RACH) associated with the vehicle according to a last known broadcast channel (BCH). When the jamming is detected, at least one last known neighbor serving cell from a stored data structure is determined, and the emergency message is broadcast on one or more second RACHs associated with each of the at least one last known neighbor serving cells. | 06-23-2011 |
| 20110151833 | Apparatus And Method For Detecting A Cloned Base Station - Communications are established between a base station and a mobile unit. The mobile unit analyzes the content of at least some information received from the base station relating to neighboring cells. When the analyzing indicates that the base station is a cloned base station, a warning is initiated to the user. | 06-23-2011 |
| 20110151834 | Apparatus And Method For Determining An Invalid Base Station - It is determined whether a base station is an invalid base station. At an electronic device at the vehicle, communications are wirelessly received from a base station. It is determined whether the base station is an invalid base station based at least in part upon at least one security parameter included in the received communications. | 06-23-2011 |
