Step 5, host computer judge whether UE actual emission power meets the demands, if met the demands, complete power and control detection calibration; Otherwise expect the power control ratio of each power construction quality of the drift correction of transmitting power according to each power construction quality actual emission power and this power construction quality, revised power control ratio is sent to UE;
Step 6, UE upgrade power control ratio table; Return step 2 to perform.
2. method according to claim 1, is characterized in that, described step 403 comprises:
This is less than current P_max and M the performance number that both differences are greater than the performance number of default thresholding THp follow-up compares with P_max one by one, if there is performance number to be greater than P_max, using this performance number as P_max, returns step 402 and perform;
Described M is default threshold value.
3. method according to claim 1, is characterized in that, described step 413 comprises:
This is greater than current P_min and M the performance number that both differences are greater than the performance number of default thresholding THp follow-up compares with P_min one by one, if there is performance number to be less than P_min, using this performance number as P_min, returns step 412 and perform;
Described M is default threshold value.
4. method according to claim 1, is characterized in that:
Described step 423 comprises, this is less than current P_down_max and M the performance number that both differences are greater than the performance number of default thresholding THp follow-up compares with P_down_max one by one, if there is performance number to be greater than P_down_max, using this performance number as P_down_max, return step 422 and perform;
Described step 426 comprises further, this is greater than current P_up_min and M the performance number that both differences are greater than the performance number of default thresholding THp follow-up compares with P_up_min one by one, if there is performance number to be less than P_up_min, using this performance number as P_up_min, return step 425 and perform;
Described M is default threshold value.
