Adaptive frequency channel assignment based on battery power level in wireless access protocols
First Claim
1. A method of managing mobile stations in a wireless network, comprising the steps of:
- receiving, at a base station, a signal from a first mobile station that its battery power is below a threshold value;
assigning, at the base station, 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
transmitting the assignment to the first and other stations.

Abstract
A method and system adapt scheduling priorities in a wireless communications system to conserve battery power in mobile stations operating within the system. A base station, within the system, receives battery power level information and other setup information from mobile stations operating within the service area of the base station during call setup procedures. Based on the battery power level information and other setup information, the base station assigns frequency channels to the mobile stations so that those mobile stations having battery power levels below a threshold value are assigned frequency channels that have lower interference levels than frequency channels assigned to other mobile stations. The frequency channel assignments are transmitted to the mobile stations.
