摘要： A system and method for the detection of fraudulent use of a wireless telephone system includes a fingerprint analyzer that identifies an unauthenticated wireless telephone as authorized or fraudulent based on a fingerprint of the unauthenticated wireless telephone. The system maintains a valid destination list specific for each authorized wireless telephone. Each valid destination list contains destinations considered to be valid for that particular authorized wireless telephone. When an unauthenticated wireless telephone transmits a call request containing a destination, the system classifies the call as valid when the destination is in the valid destination list for the authorized wireless telephone regardless of whether the fingerprint analyzer identifies the unauthenticated wireless telephone as fraudulent. The system may bypass or terminate the fingerprint analysis, or simply ignore the result of the fingerprint analysis by the fingerprint analyzer. The system also maintains an invalid destination list specific for each authorized wireless telephone with destinations considered to be invalid for that particular authorized wireless telephone. Calls to such destinations are blocked. The system further maintains a suspicious destination list containing destinations considered to be potentially fraudulent. When the destination contained in the call request is in the suspicious destination list, the fingerprint analysis is performed with a higher threshold to require a closer match between a fingerprint of the unauthenticated wireless telephone and a stored fingerprint of the corresponding authorized wireless telephone.

摘要： A method and apparatus which provide the ability to disrupt normal completion of a specific call made through a wireless telephone system. The specified call can be forced to be immediately ended, re-routed immediately to a selectable destination, or linked to a local voice frequency interface. The disruption of the call can occur at any point in time over the duration of the call. The decision to disrupt the call, as well as which action to take against the call, can be selected manually by a human or automatically through a standard data interface provided. The call disruption apparatus can be interfaced to the wireless system through a circuit physically connected to the wireless telephone system equipment, or through a modulated radio frequency interface.

摘要： A system and method extracts a portion of a transmitted waveform and compares the transmission characteristics of the extracted waveform to determine if they match a stored fingerprint associated with the transmitter, such as a cellular telephone. The system adaptively creates fingerprint data by storing a plurality of waveforms believed to be from a particular transmitter and calculates the variability of the individual transmissions with respect to a composite mean waveform of the transmission characteristics. The system emphasizes the variability between the individual waveforms and the composite mean waveform and determines variability values for each of the individual waveforms in the fingerprint. When the system receives an additional unidentified transmission purported to be from the transmitter with the stored fingerprint, the system determines whether the variability of the unidentified waveform fits within the predetermined margins of variability for the fingerprint. If the variability of the unidentified waveform is less than a predetermined variability threshold, the system considers the waveforms to be a suitable match. The system can adaptively include new waveforms in the fingerprint by determining whether the newly-received transmission characteristics meet a series of criteria for inclusion in the fingerprint. In addition, the system analyzes the newly-received waveform and all waveforms forming the fingerprint to determine if any of the waveforms exceed a predetermined maximum variability value. A waveform that exceeds the maximum variability value is eliminated from the fingerprint. The system is easily automated, thus providing a useful analysis technique for communications network such as cellular telephone systems where a large population of transmitters with similar transmission characteristics are operating at any given time.

摘要： This disclosure is directed to power delivery including out-of-band communication. In general, a device to be charged and a charging device may interact using two separate wireless signals. A first wireless signal (e.g., a radio frequency (RF) signal) may be employed to charge the device. A second wireless signal of a different type (e.g., an infrared (IR) signal) may be employed for inter-device communication. An example device may comprise a power module to receive a first wireless signal, a transmitter to transmit a second wireless signal, and a charging control module. The first wireless signal may be for conveying power from a charging device to the device, the second wireless signal may be for transmitting information from the device to the charging device, and the charging control module may be to cause the transmitter to transmit the second wireless signal based on an indication received from the power module.
