Abstract
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).
