Abstract
A wireless communication system (200) estimates (303) the location of a mobile station (215) when a degradation in the mobile station's communication occurs due to interference, and stores (305) the location estimate in a database. The database is used to determine the potential for the mobile station (215) within the wireless communication system to receive interference based on its estimated location or its proximity to the known interference location. When the mobile station (215) is within a predetermined distance of the known interference location, the likelihood for the mobile station (215) to experience a degradation in call quality, duration, etc. increases. To mitigate the degradation due to interference, an alternate carrier (104) is found and if available, the mobile station's communication is handed off to the alternate carrier (104). Attenuation can also be added in the front-end of the mobile station (215) to mitigate the degradation due to interference.
