Abstract:
In a radio mobile communication system adopting a hierarchical cell structure comprising a plurality of layers having respective cells of different sizes, the threshold value of the number of times of cell reselections and/or the threshold value of the time required to measure the number of times of cell reselections are set for each layer. A mobile station device compares the number of times of cell reselections in a specific time and/or the time required for the number of times of cell reselections to reach a specific value with the threshold values and selects a transfer target cell.
