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.
Méthode et système adaptant les priorités d'ordonnancement d'un système de télécommunications sans fil de manière à économiser l'énergie des piles des stations mobiles du système. Lors des procédures d'établissement d'appels, une station de base, à l'intérieur du système, reçoit des stations mobiles de sa zone de desserte de l'information d'établissement d'appel comprenant des données sur le niveau d'énergie des piles. Cette information permet d'affecter aux stations mobiles dont les piles ont un niveau d'énergie inférieur à un certain seuil, des canaux ayant un niveau de brouillage plus faible que pour les autres stations mobiles. Les affectations de canaux sont transmises aux stations mobiles.
