Adaptive frequency channel assignment based on battery power level in wireless access protocols

A method of managing mobile stations in a wireless network, comprising the steps of:

• receiving, at a base station, a signal from each of a plurality of mobile stations, each signal indicating a battery power level of a corresponding mobile station;
• assigning, at the base station, a frequency channel to each mobile station based on the indicated battery power level of each mobile station and on the interference level of each frequency channel;
• and
• transmitting the assignment to each mobile station.

A system for managing mobile stations in a wireless network, comprising:

• means for receiving at a signal from a first mobile station that its battery power is below a threshold value;
• means for assigning a frequency channel to the first mobile station that has a lower interference level than frequency channels assigned to other mobile stations, in response to receipt of the signal;
• and
• means for transmitting the assignment to the first and other stations.
