| 1. A mobile communication terminal, comprising:
an error rate measuring unit for measuring an error rate of a message for a time period;
a checking unit for checking a size of the measured error rate and a size of a threshold value; and
a controller for controlling a cell selection depending on the measured error rate and the threshold value,
wherein the controller determines cell section by
calculating a ranking value of a serving cell and a ranking value of one or more neighboring cells using reception power quality
values of the serving cell and of the one or more neighboring cells;
comparing the measured error rate with the threshold value, if the ranking value of a neighboring cell of the one or more
neighboring cells is greater than the ranking value of the serving cell during a duration of a timer; and
performing the cell selection if the measured error rate is greater than the threshold value.
