Step 3, makes terminal and radio communication tester connect after calibration;
Step 4, program enables temperature monitoring unit automatically.Temperature monitoring unit can utilize radio frequency chip thermistor that is inner or terminal self to obtain the information of temperature, because temperature-compensating is compensation terminal being done to whole piece transmitting chain, how temperature information obtains unimportant.The actual temperature during work of this unit monitoring terminal, when terminal temperature reaches design temperature, such as T
1afterwards, program sends the order of inner loop power test to instrument, temperature monitoring unit break-off afterwards.
Step 5, inner loop power test starts, and data acquisition unit starts collecting test data, and by the data that collect stored in database, after to be tested and data acquisition all completes, terminal returns maximum Qigong state, and sends request to temperature monitoring unit.
Step 6, repeats step 4 and step 5, until detecting information corresponding to all design temperatures all gathers complete, program jumps out circulation, enters data processing unit.
Step 7, in data processing unit, will collect data analysis, judge whether to exist the power points that step-length exceedes regulation step-length; If there is not this type of power points, then the result of output power back off is after original value, EP (end of program).
Step 8, if there is the power points that step-length exceedes regulation step-length in judgement, then think that inner-loop power control has problems, need to adjust its transmitting power, program goes to judge be decreased to this power points occurred in the process of minimum emissive power one by one with regulation step-length from maximum transmission power further, or occur in the process increasing to maximum power from minimum emissive power with regulation step-length one by one, whether exist all exceed regulation step-length in two processes point near same power points.This that is be judging whether to need to carry out temperature-compensating.
Step 9, all exceedes the point of regulation step-length near same power points, because temperature-compensating is the compensation for whole gain level, so enter temperature-compensating program if existed in two processes; Otherwise, then ingoing power amplifier (PA, Power Amplifier) gain switching point compensation program, because it is in order to compensate the situation bringing only emergent power control deviation in an above-mentioned process because of the factor such as non-linear of PA self that PA gain switching point compensates.
Step 10, power-off restarting terminal after gained offset write memory will be calculated;
Step 11, repeats above-mentioned steps 2 to 10, until program judges to show that inner-loop power control is no problem, transmitting power is without the need to adjusting again.The best power offset obtained is exported, and termination routine.
When described terminal needs the power of multiple channel to control all to reach requirement, testing the reference channel of described terminal and adjust obtains after power compensating value is less than default power threshold, gather the test data of each gain level under other channels successively, and carry out power back-off.Fig. 5 is the flow chart of the frequency compensation method of terminal inner-loop power control, and as shown in Figure 5, it specifically comprises:

S503, successively gather each test frequency test data;
The test data by gathering each gain level under each channel in the embodiment of the present invention, the temperature compensation value X of temperature spot, gain level and correspondence
iNcorresponding relation concrete as shown in Figure 4.
S504, according under described test data determination different channels, different gains grade each power control abnormity point frequency compensation value and preserve;
