摘要： A method for synchronizing base stations (104, 106, 108, 110) or radio ports in a communication system (100) such as a cordless or cellular telephone system uses a mobile station (114) or handset for synchronizing unsynchronized base stations. The mobile station (114) is first synchronized to a reference base station. The mobile station (114) then initiates communication with the unsynchronized base station and calculates a synchronization adjustment. The mobile station (114) transmits the synchronization adjustment to the unsynchronized base station which uses the synchronization adjustment to adjust its time base.

摘要： A radiotelephone handset (120) includes an antenna (122) and receiver (124) for receiving a control channel from a plurality of base stations (102, 104, 106). A time division multiple access controller circuit (126) coupled to the receiver stores all received control channel information in a captured data buffer (134). Under control of a processor (128), the handset identifies as candidate suitable base stations those base stations having acceptable received signal strength, acceptable identity or system capability. From the candidates, the handset (120) chooses a suitable base station having acceptable signal quality, access rights and system capability and synchronizes communication with the suitable base station.

摘要： A method and apparatus reduces power consumption in a portable communication device (104) by predicting a user's location, movement and actions. The portable communication device (104) is powered by a battery (120) and includes a battery control (122) for decoupling portions of the communication device (104) from the battery. Historical records of control channel and call activity are maintained in memory (117) at the communication device (104). This data is used to predict calls. This permits the communication device (104) to conserve power in the battery (120) when no call activity is likely. The stored data is also used to predict what control channels should be scanned to search for a nearby base station (102). This permits the communication device (104) to scan a reduced number of control channels and reduces the time duration necessary for powering up the receiver (108) of the communication device (104).

摘要： A data processor (20) which flexibly encrypts data within different address ranges includes an encryption determination circuit (50) to monitor an address conducted on an internal address bus (22) and when the address is within certain predefined ranges, perform encryption or decryption of address and/or data. For example the encryption determination circuit (50) may be used to selectively enable a data encryption-decryption circuit (60). When the data encryption-decryption circuit (60) is disabled, data conducted on an internal data bus (23) becomes "cleartext", i.e., non-encrypted. In one embodiment, the data encryption-decryption is performed in partial dependence on the address itself, and the address conducted to the external address bus is itself selectively encrypted as well.

摘要： A method and apparatus whereby a communication unit (10) transmits a communication channel request and the nearest base site (12) makes the communication channel grant or allocation. A base site receives the channel request signal, measures the received signal strength (RSSI) level of the received signal, and if that level is above a threshold level, a communication channel is allocated to the requesting communication unit, thus establishing a communication link. If the channel request signal does not have an RSSI level above the threshold, the base site delays the grant of a communication channel for a period inversely proportional to the measured RSSI level to allow other base sites the opportunity to grant a communication channel to the requesting communication unit. If the base site determines that another base site has granted a communication channel to the requesting communication unit, the allocation process is stopped, and the base site continues scanning for channel request signals.
