Abstract:
1. A method of performing cell re-selection at a user equipment in a wireless communication system, the method comprising: measuring a signal characteristics value of at least one cell among a number of cells detected in a first time interval and in a second time interval, respectively; calculating a variation of the signal characteristics value of the at least one common cell, wherein the at least one common cell is commonly detected by the user equipment in both of the first time interval and the second time interval; giving a weight value to the variation of the signal characteristics value according to a change level in the number of cells detected in the first time interval and the second time interval, wherein the change level in the number of cells is a value obtained by subtracting the number of the at least one common cell from a total sum of the at least one cell among the number of cells; determining a scaling factor (SF) corresponding to the value of the given weight value; determining an updated restriction time by multiplying a previous restriction time by the determined SF; and performing a cell re-selection procedure according to the updated restriction time.
