    摘要: A method for storing and managing rekeying information for a secure communication system, as well as for carrying out a rekeying operation. Encryption key variables stored in memory (301) are represented by mnemonics (303) as part of an editable data base (302) that is arranged in the same order as communication unit key storage locations. Each communication unit (305) within the system is assigned to a specific group (304), while each group (304) is assigned to a particular editable data base (302).

    摘要: A method is described for launching a vehicular camera application residing on a docked mobile communication device, such as a smartphone, tablet computer, or mp3 player, for example. A common feature for the many choices of a mobile communication device is that the mobile communication device comprises embedded data processing capability. The launching operation of the vehicular camera application includes detecting a communicative coupling of the mobile communication device with a docking device; and thereafter initiating the vehicular camera application that resides on the mobile communication device. Images are displayed on the mobile communication device that was captured by a vehicular camera or a camera integrated with the mobile communication device or communicatively coupled to the mobile communication device. The associated camera may be controlled by the vehicular camera application

    摘要: In a mobile communications system, a plurality of base stations may receive the same signal, whereby the "best" reception may be determined. The plurality of received digital signals are combined to form a majority signal. Each of the received digital signals is compared to the majority signal to estimate the bit-error-rate (BER) of each received signal. If the difference between the highest and lowest BER is less than a predetermined threshold, the majority signal is selected for reception. Conversely, if the BER difference is greater than the predetermined threshold, the received digital signal with the lowest BER is selected for reception. Thus, the signal with the lowest BER is selected to provide the best possible communications.

    摘要: Within a communication system, an encryption controller receives unit identification information from a plurality of encrypting/decrypting communication units. For any individual communication unit, the encryption controller uses the unit identification associated with that transmitting communication unit to determine if it contains updated encryption key information. If the transmitting communication unit is not currently updated, a group call is used to send the current encryption key information to all communication units within the transmitting communication unit's group, thereby updating all active, non-current communication units. After a first predetermined period of time has elapsed, this process is allowed to repeat.
