3 202 and a layer 2 206 and is coupled to a layer 1 208 the layer 3 202 is for performing radio resource control rrc the layer 2 206 is for performing link control and the layer 1 208 is physical layer in the prior art when a radio link failure occurs in a ue during performing some application services in cell_dch state a timer t 314 t 315 will be started and can be expired while performing a cell update procedure after the ue responds to a cell update confirm message an information element ie u201c t314 expired u201d and an ie u201c t315 expired u201d in a variable rb_timer_indicator are not cleared if the ue is kept in connected mode the ie u201c t314 expired u201d and the ie u201c t315 expired u201d respectively represent the expiration states of the timer t 314 and the timer t 315 thereby when the ue performs the cell update procedure again the rnc of utran will consider the ie u201c t314 expired u201d u201c t315 expired u201d true via the received cell update message in this situation the present invention provides a variable clearance program code 220 in the layer 3 202 to clear the variable rb_timer_indicator for improving reset mechanism of radio link re establishment timers the timer t 314 and the timer t 315 so as to prevent the utran from unpredictable operations caused by incorrect received ie u201c t314 expired u201d u201c t315 expired u201d please refer to fig3 which illustrates a schematic diagram.
