Abstract
Interference and bit error rate measurements are made on the uplink and downlink to determine communications quality. Mobile station mobile assisted hand-off (MAHO) functionality is utilized to make the downlink measurements. Following filtering, the measurements are evaluated to identify potential candidates for reallocation. In one type of evaluation, when measured downlink bit error rate on a selected frequency is lower than a threshold and is worse than measured uplink bit error rate, then a better quality candidate is chosen to replace the selected frequency. In another type of evaluation, when a best available candidate has better interference than a worst quality one of the selected frequencies, that best candidate is chosen to replace the selected frequency.
