Abstract
The present invention provides a method and apparatus for controlling the operations of a battery-powered mobile station based on the capacity of its battery. In accordance with the present invention, the mobile station monitors the capacity of its battery to determine whether it has fallen below any one of a plurality of threshold capacity values. When the capacity of the battery falls below the highest of these threshold values, the mobile station sends a registration cancellation message to the serving system and then disables the transmit operation in order to conserve power. Other operations of the mobile station are systematically disabled if the battery capacity falls below one or more lower threshold values.
