Abstract

In a radiocommunication system including at least one base station and a mobile station connected across a first radio channel to the base station, the signal strengths of the first radio channel and neighboring radio channels are measured in the mobile station to determine whether reselection to a neighboring radio channel is necessary. Each radio channel is measured at various points in a frame period or in different frame periods, the measurements occurring in different time slots. The points at which the signal strength measurements of each radio channel are made may be rotated among the different frame periods, the measurements may be made at random points in the different frame periods, or the starting times of the measurements may be rotated among or occur randomly in the different frame periods. Alternately, the signal strengths of each radio channel may be measured at different points in a single frame period. The measurements of the signal strength of the each radio channel are averaged, and the averaged measurements are compared to determine whether reselection from the first radio channel to a neighboring radio channel is necessary.
