Mobile station operations management based on battery capacity
First Claim
1. In a communications system comprising a base station in communication with a mobile station, said mobile station being powered by a battery, a method for controlling the operations of said mobile station based on the capacity of said battery, the method comprising the steps of:
- selecting at least one threshold capacity value for said battery;
monitoring the capacity of said battery to determine whether it has fallen below said at least one threshold capacity value; and
when the capacity of said battery falls below said at least one threshold capacity value;
generating a perceptible warning in said mobile station; and
sending a registration cancellation message from said mobile station to said base station.

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.

12. A mobile station powered by a battery and communicating with a base station, the mobile station comprising:
-
a transmitter for transmitting messages to said base station; a receiver for receiving messages from said base station; means for monitoring the capacity of said battery to determine whether it has fallen below at least one predetermined threshold value; and means for sending a registration cancellation message to said base station and for disabling said transmitter and enabling said receiver when the capacity of said battery falls below said at least one threshold capacity value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
