Include sub-step S301 to sub-step S303.
Sub-step S301: the corresponding maximum mark of maximum power level is obtained from the corresponding calibration power value of each power grade
Quasi- performance number.
Specifically, storing the corresponding calibration power value of each power grade in advance inside mobile terminal.Wherein, each power
The corresponding calibration power value of grade indicates that the corresponding calibration power value of each power grade calibrated when mobile terminal factory (permits
Permitted the floating range for having certain).The corresponding calibration power value of each power grade can be stored in the form of array, can also be with table
The form of lattice indicates, uses the former in present embodiment.
In present embodiment, gsm system include four frequency ranges, successively are as follows: GSM850, GSM900, GSM1800,
GSM1900.Each frequency range indicates the corresponding calibration power value of each power grade respectively with array P0, P1, P2, P3, wherein works as movement

The corresponding calibration power value of 15 power grades of GSM850 is respectively corresponded to p19, the power grade that p5 to p19 is represented is by height
To low arrangement；
P1=(p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18, p19), wherein p5
The corresponding calibration power value of 15 power grades of GSM900 is respectively corresponded to p19, the power grade that p5 to p19 is represented is by height
To low arrangement；
P2=(p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15), wherein p0 is arrived
P15 respectively corresponds the corresponding calibration power value of 16 power grades of GSM1800, and the power grade that p0 to p15 is represented is by height
To low arrangement；
P3=(p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15), wherein p0 is arrived
P15 respectively corresponds the corresponding calibration power value of 16 power grades of GSM1900, and the power grade that p0 to p15 is represented is by height
To low arrangement.
That is, corresponding to four frequency ranges of gsm system mobile phone, maximum power level is respectively 5 grades, 5 grades, 0 grade, 0 grade, most
Big calibration power value is respectively P0 (5)=33dBm, P1 (5)=33dBm, P2 (0)=30dBm, P3 (0)=30dBm.
Sub-step S302: the rollback power difference between maximum calibration power value and rollback power parameter is calculated.
That is, rollback power parameter is denoted as UPR in present embodiment, corresponding to four frequency ranges of gsm system, rollback power
Difference is followed successively by P0 (5)-UPR, P1 (5)-UPR, P2 (0)-UPR, P3 (0)-UPR.
Sub-step S303: the corresponding calibration power value of more each power grade and rollback power difference, and by it is therein compared with
Small person is as the corresponding rollback performance number of the power grade, to generate the corresponding rollback performance number of each power grade.
For example, each frequency range indicates the corresponding rollback power of each power grade respectively with array UPR0, UPR1, UPR2, UPR3

P5 to p19 respectively corresponds the corresponding rollback performance number of 15 power grades of GSM850；
UPR1=(p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18, p19), wherein
P5 to p19 respectively corresponds the corresponding rollback performance number of 15 power grades of GSM900；
UPR2=(p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15), wherein p0
The corresponding rollback performance number of 16 power grades of GSM1800 is respectively corresponded to p15；
UPR3=(p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15), wherein p0
The corresponding rollback performance number of 16 power grades of GSM1900 is respectively corresponded to p15.
Corresponding to GSM850 frequency range and GSM900 frequency range, have:
UPRm (n)=MIN (Pm (n), Pm (5)-UPR), wherein m=0,1；N=5 ... 19 (formula 1)
For GSM1800 frequency range and GSM1900 frequency range, have:
UPRm (n)=MIN (Pm (n), Pm (0)-UPR), wherein m=2,3；N=0 ... 15 (formula 2)
It the following is and illustrated with GSM850 frequency range example:
P0=(33,31,29,27,25,23,21,19,17,15,13,11,9,5)；
As the rollback power parameter UPR=11 of acquisition for mobile terminal, rollback power difference is P0 (5)-UPR=22, then
It is obtained according to formula 1,
UPR0=(22,22,22,22,22,22,21,19,17,15,13,11,9,5)；
Array UPR0 is thereby produced, i.e., the corresponding rollback performance number of each power grade in GSM850 frequency range.Similar, it moves
Dynamic terminal generates the corresponding rollback power of each power grade in other three frequency ranges (GSM900, GSM1800, GSM1900) respectively
Value.By the value in array UPR0 it is found that the value of UPR0 (n) is substantially dependent on rollback performance number UPR.
Step S4: being open state by preset rollback traffic sign placement.
Specifically, mobile terminal internal preset has a rollback mark, has and open and close two states.When this time
Move back mark be open state when, indicate allow mobile terminal use the corresponding rollback performance number of each power grade as transmission power
Reference frame；When the rollback mark is in off state, indicate that forbidden moves terminal uses the corresponding rollback of each power grade
Reference frame of the performance number as transmission power, i.e. mobile terminal use the corresponding calibration power value of each power grade as transmitting
The reference frame of power.
It is automatically open state by rollback traffic sign placement after mobile terminal execution complete step S3 in present embodiment.
Step S5: according to the current transmitting of each power grade corresponding rollback performance number and current power level setting signal
Performance number, current transmission power are the corresponding rollback performance number of current power level.
Specifically, after mobile terminal access channel, it can (such as the power control for carrying out self-channel received according to the actual situation
After order) current power level is generated, mobile terminal is according to the corresponding rollback performance number of each power grade and current power level
The current transmission power value of setting signal.That is, mobile terminal can obtain this currently from the corresponding rollback performance number of each power grade
The corresponding rollback performance number of power grade, and using the rollback performance number as the current transmission power value of signal.
Step S6: judge whether rollback mark is open state.If so, entering step S5；If it is not, entering step S7.
That is, the state for the mark that retracts can also have user to manually set other than setting in step S4.For example, (mobile
Terminal in last time using when be set rollback power parameter), user can manually set the rollback mark in mobile terminal
It is set to open state or closed state, mobile terminal can choose whether according to the rollback mark using each function before sending signal
Reference frame of the corresponding rollback performance number of rate grade as transmission power.
Step S7: according to the current transmitting of each power grade corresponding calibration power value and current power level setting signal
Performance number, current transmission power are the corresponding calibration power value of current power level.
That is, mobile terminal can obtain the corresponding standard of the current power level from the corresponding calibration power value of each power grade
Performance number, and using the calibration power value as the current transmission power value of signal.
The step of various methods divide above, be intended merely to describe it is clear, when realization can be merged into a step or
Certain steps are split, multiple steps are decomposed into, as long as comprising identical logical relation, all in the protection scope of this patent
It is interior；To adding inessential modification in algorithm or in process or introducing inessential design, but its algorithm is not changed
Core design with process is all in the protection scope of the patent.
Second embodiment of the present invention is related to a kind of method of adjustment of signal transmission power, as shown in Figure 3.Second implements
