METHOD FOR CONTROLLING OUTER LOOP POWER FOR TERMINAL HAVING MULTIPLE CHANNEL STRUCTURE

PURPOSE: A method for controlling an outer loop power for a terminal having a multiple channel structure is provide to control an outer loop power proper for multiple communication channels having different service qualities each other. CONSTITUTION: A base station controller performs an outer loop power control according to a target frame error rate of each channel for every reception communication channel, and controls virtual power control threshold values. According to an operation mode of the outer loop power control, the base station controller uses the controlled virtual power control threshold values, and controls power control threshold values for controlling a real inner loop power. The base station controller monitors threshold value differences between virtual power control threshold values of master channels controlled by the outer loop power control of each channel and virtual power control threshold values of slave channels, and compares the threshold value differences with a predetermined reference value. If the threshold value differences exceed the reference value, the base station controller is operated in a fixed mode. If the threshold value differences do not exceed the reference value, the base station controller is operated in a normal mode.
