But, it will be understood by those skilled in the art that, in each enforcement mode of the present invention, propose many technology details to make reader understand the application better. But, even if there is no these technology details and based on the many variations of following enforcement mode and amendment, it is also possible to realize the technical scheme that each claim of the application is claimed.
The first enforcement mode of the present invention relates to the production method of a kind of back-off value. Idiographic flow is as shown in Figure 1.
Step 10: move back between coefficient, according to the cell voltage of mobile terminal and voltage and returning, the corresponding relation preset and produce voltage and return and move back coefficient.
Specifically, mobile terminal internal reservoir have voltage and return moves back between coefficient preset corresponding relation, this corresponding relation can synopsis form exist, as shown in table 1 for voltage-return move back coefficient vs table. After mobile terminal obtains the cell voltage of its inside, question blank 1 returns move back coefficient to obtain voltage corresponding to this cell voltage. Wherein, cell voltage is represented by V, and voltage returns and moves back coefficient by PbackoffbattRepresent.
Table 1
| Cell voltage (V) | Voltage returns and moves back coefficient (Pbackoffbatt) |
| V>3.6 | 0 |
| 3.5<V��3.6 | 1 |
| 3.4<V��3.5 | 1.5 |
| V��3.4 | 2 |
Step 11: move back between coefficient, according to the mainboard temperature of mobile terminal and temperature and returning, the corresponding relation preset and produce temperature and return and move back coefficient.
Specifically, mobile terminal internal reservoir have mainboard temperature and return moves back between coefficient preset corresponding relation, this corresponding relation can synopsis form exist, as shown in table 2 for temperature-return move back coefficient vs table. After mobile terminal obtains the mainboard temperature of its inside, question blank 2 returns move back coefficient to obtain temperature corresponding to this mainboard temperature. Wherein, mainboard temperature is represented by T, and temperature is returned and moved back coefficient by PbackoffTempRepresent.
Table 2

| T<40 | 0 |
| 40��V<50 | 0.5 |
| 50��V<60 | 1 |
| V��60 | 1.5 |
Step 12: return according to back-off parameter generation current power and move back value; Back-off parameter at least comprises voltage and returns and move back coefficient and temperature is returned and moved back coefficient. Wherein, step 12 comprises following sub-step.
Sub-step 121: calculating voltage returns and moves back coefficient and temperature is returned and moved back coefficient sum as the first intermediate parameters.
That is, the first intermediate parameters is by (Pbackoffbatt+PbackoffTemp) represent.
Sub-step 122: obtain the first intermediate parameters and return as current power with the smaller in limit value in theory and move back value.
Wherein, in theory limit value by PBackoffLimitRepresenting, current power is returned and is moved back value by PbackoffRepresent, then current power is returned the calculation formula moving back value and is: Pbackoff=MIN [Pbackoffbatt+PbackoffTemp, PBackoffLimit]��
In enforcement mode, the first intermediate parameters (Pbackoffbatt+PbackoffTemp) for improving the usefulness of back-off; Limit value P in theoryBackoffLimitSet the threshold value of back-off, return with power-limiting and move back excessive, avoid occurring in situation about may be reduced significantly from the communication efficiency of the terminal away from base station. Practical experience according to those skilled in the art, it is proposed that PBackoffLimit�� 2.5dBm (decibel milliwatt); Preferably, P in present embodimentBackoffLimitValue be 2.5dBm. Therefore, in present embodiment, Pbackoff=MIN [Pbackoffbatt+PbackoffTemp, 2.5].
Such as, the cell voltage obtained when mobile terminal is V=3.55v, and mainboard temperature is T=46 DEG C, in theory limit value PBackoffLimitDuring=2.5dBm, computation process is as follows:
First, obtain voltage according to table 1 to return and move back coefficient, PbackoffTemp=1dBm;Obtain temperature according to table 2 to return and move back coefficient, PbackoffTemp=0.5dBm.
Then, calculate current power to return and move back value. The calculation formula P moving back value is returned according to current powerbackoff=MIN [Pbackoffbatt+PbackoffTemp, PBackoffLimit], it is seen that, Pbackoff=MIN [1+0.5,2.5]=1.5dBm.
The 2nd enforcement mode of the present invention relates to the production method of a kind of back-off value, as shown in Figure 2. 2nd enforcement mode is the improvement on the first enforcement mode basis, and key distinction part is: in second embodiment of the invention, and back-off parameter also comprises artificial preset value. That is, using artificial preset value as the considerations producing back-off value; Thus, in the adjustment process of the signal transmission power of mobile terminal, user can play certain guide effect so that the adjustment more realistic situation of signal transmission power out.
In present embodiment, step 20,21 respectively to the step 10 in the first enforcement mode, 11 similar; Step 22 comprises sub-step 221��223, and sub-step 221 is similar to the sub-step 121 of step 12 in the first enforcement mode, and similar steps repeats no more herein.
Wherein, in sub-step 222 and the first enforcement mode, the sub-step 122 of step 12 is not identical, and, sub-step 223 is the newly-increased step in the 2nd enforcement mode. Being described as follows of sub-step 222,223:
Sub-step 222: obtain the first intermediate parameters with the smaller in limit value in theory as the 2nd intermediate parameters.
Wherein, the 2nd intermediate parameters is by PBackoff-1Represent, then the calculation formula of the 2nd intermediate parameters is: PBackoff-1=MIN [Pbackoffbatt+PbackoffTemp, PBackoffLimit]��
Sub-step 223: the greater obtained in the 2nd intermediate parameters and artificial preset value returns as current power and moves back value.
Wherein, artificial preset value is by PBackoff-2Represent, then current power is returned the calculation formula moving back value and is: Pbackoff=MAX [PBackoff-1, PBackoff-2]��
In present embodiment, artificial preset value can be set as required by user. That is, after mobile terminal produces parameter setting requests, mobile terminal provides a parameter setting interface to user, and this parameter setting interface such as comprises input frame, and mobile terminal receives the artificial of user's input by this input frame and presets.
Specifically, mobile terminal inside sets multiple optional time in advance and moves back grade: 0,1,2,3 ... n (n is integer), moves back the corresponding artificial preset value of grade for each time. That is, user can input back in the input frame of parameter setting interface and move back grade and move back artificial preset value corresponding to grade for each time to select. Such as, move back difference one between the corresponding artificial preset value of grade for each time and return the long P that regressesback. If that is, user's input return that to move back grade be 0 grade, then PBackoff-2=0, represent that artificial preset value is 0 (namely do not return and move back); If user's input return that to move back grade be 1 grade, then PBackoff-2=Pback, represent that artificial preset value is Pback(dBm); If user's input return that to move back grade be 2 grades, then PBackoff-2=2*Pback, represent that artificial preset value is 2*Pback(dBm); If user's input return that to move back grade be 3 grades, then PBackoff-2=3*Pback, represent that artificial preset value is 3*Pback(dBm); Analogize successively. Wherein, the long P that regresses is returnedbackValue can set according to practical situation. But, the set-up mode of artificial preset value is not imposed any restrictions by present embodiment, in other enforcement mode, can also be: mobile terminal presets the span of an artificial preset value, and user can input any number in the span of this artificial preset value in the input frame at optimum configurations interface.
It should be noted that, the 2nd intermediate parameters P in present embodimentBackoff-1Value substantially return with the current power in the first enforcement mode that to move back value be equal, and the current power in present embodiment is returned, and to move back value be substantially utilize artificial preset value the current power in the first enforcement mode to be returned to move back value (i.e. the 2nd intermediate parameters P in present embodimentBackoff-1Value) revise after result.
Such as, the cell voltage obtained when mobile terminal is V=3.55v, and mainboard temperature is T=46 DEG C, in theory limit value PBackoffLimitDuring=2.5dBm (completely identical in cell voltage, mainboard temperature, in theory limit value and the first enforcement mode), computation process is as follows:
First, obtain voltage according to table 1 to return and move back coefficient, PbackoffTemp=1dBm; Obtain temperature according to table 2 to return and move back coefficient, PbackoffTemp=0.5dBm.
Secondly, calculate the 2nd intermediate parameters. Calculation formula P according to the 2nd intermediate parametersBackoff-1=MIN [Pbackoffbatt+PbackoffTemp, PBackoffLimit], it is seen that, PBackoff-1==MIN [1+0.5,2.5]=1.5dBm.
Finally, calculate current power to return and move back value. In present embodiment, if returning the long P that regressesback=0.5, artificial settings are PBackoff-2=4*Pback=2 (namely return move back grade be set to 4 grades), then return the calculation formula P moving back value according to current powerbackoff=MAX [PBackoff-1, PBackoff-2], it is seen that, Pbackoff=MAX [1.5,2]=2dBm.
As from the foregoing, when in cell voltage, mainboard temperature, in theory limit value and the first enforcement mode complete identical time, owing to the 2nd enforcement mode also using artificial preset value as correction, therefore finally calculate current power and return the current power moved back in value and the first enforcement mode and return and move back value and inconsistent. But, the current power that the mode of first, second embodiment is calculated return move back value also may identical, this depends on the difference of the artificial preset value that user sets.
The 3rd enforcement mode of the present invention relates to the inflation method of a kind of signal transmission power, as shown in Figure 3.
Step 30: according to the production method of the first or the 2nd back-off value described in enforcement mode, obtains current power and returns and move back value.
Specific descriptions please refer to first or the 2nd enforcement mode, repeats no more herein.

Sub-step 311: return the emission maximum power moving back in value amendment mobile terminal and presetting according to current power to produce the emission maximum power after revising.
Sub-step 312: the transmitted power calculation formula corresponding according to the emission maximum power after amendment and default work at present standard, produces the current transmit power of mobile terminal under work at present standard.
Present embodiment is applied to the mobile terminal that work at present standard is LTE standard. Wherein, the calculation formula of the signal transmission power P that LTE standard is corresponding is:
P=MIN (Pmax,10lgM+PO_PUSCH(j)+a(j)PL+��TF+f(j))(1)
Wherein, PmaxRepresent the emission maximum power of mobile terminal; M represents RB quantity; PO_PUSCHRepresent power reference value, by high-rise signaling instruction; A (j)={ 0,0.4,0.5,0.6,0.7,0.8,0.9,1}, represents that cel l path loss compensates, by high-rise signaling instruction; PL represents the downlink path loss that UE measures; ��TFRepresent the power offset determined by modulation coding mode and data type; F (j) represents closed-loop power control adjustment amount.
