Below will do further detailed explanation to mobile communication terminal of the present utility model.
No matter be 2G or the mobile communication terminal of 3G, all require power controlled, that is to say that requirement can be exported different performance numbers.For example be operated in the Class 4 class GSM terminals of EGSM (Extended Global System for Mobile enhancement mode global system for mobile communications) frequency band, be required to realize class 5-19 15 grades of power controls altogether.Wherein power grade 5 is peak power grades, and 3Gpp (3G communications protocol) requires mobile communication terminal under common environment for use, and the power of this grade output is controlled at 33 ± 2dBm scope.
And in the design process of mobile communication terminal, the designer can determine the desired value of peak power grade, and this desired value is called as maximum calibration power (P
Cal).Such as said GSM (Global System for Mobile Communications, global system for mobile communications) terminal, the designer may set maximum calibration power (P
Cal) be 32.5dBm.This value is that comprehensive many-sided factor is determined, as conductive performance, radiance, power consumption and absorption of human body than indexs such as (SAR).But in fact, the actual maximum available power (P of mobile communication terminal
Max) be greater than maximum calibration power (P
Cal).This is because if under normal operating position (being that network coverage signal is when belonging to normal range (NR)), if with P
CalBe set at P
Max, index such as power consumption, SAR is unfavorable for that with variation the user uses so.
And in some specific occasion, as need carrying out urgent call in the zone (network coverage signal does not belong to normal range (NR) as described in being) of network coverage poor signal, what needed most assurance this moment is the carrying out of communication, rather than other indexs such as power consumption.Therefore, in these occasions, wish that communication terminal can use its actual maximum available power P

Step 1: the calibration software that moves on mobile communication terminal (mobile phone) start and the computer connects;
Step 2: radio frequency (R F) signal of calibration software order mobile communication terminal emission standard, its transmitting power is by an initial calibration parameter Calcode control;
Step 3: the calibration instrument power detection device (as Agilent8960, R﹠amp; SCMU200) detect the RF signal, measure power P
