Patent ID: 7263363

Claim:
A method for maximizing intermodulation interference protection comprising the steps of: during a mobile assisted handoff between radio channels within a cell site within a communication system; scanning a plurality of radio channels within the site; measuring signal power for each of the scanned radio channels; determining an attenuation level engaged by a continuous automatic gain control (AGC) for each of the scanned radio channels; selecting a radio channel to receive based on the measured signal power and the determined attenuation level; detecting on-channel intermodulation (IM) interference on the received radio channel; selecting a new radio channel to receive from the plurality of scanned radio channels based on the measured signal power and the determined attenuation level; detecting intermodulation (IM) interference on the selected radio channel; pre-setting receiver attenuators for the selected radio channel based on the detection of intermodulation (IM) interference and AGC attenuation level; and changing to the selected channel.
