The CIR value in each idle channel is measured. When the measured CIR value is below the threshold value Λc1, the priority of that channel is decreased; when the CIR value is between the threshold values Λc1 and Λc2, the priority is increased; and when the CIR value is above the threshold value Λc2, the priority is held unchanged. When a call occurs in a base station, the highest-priority one of idle channels with the CIR values larger than the threshold value Λc1 is allocated to that call and the priority of the allocated channel is increased.Field of SearchOptimum frequency selection | |
