Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
As shown in Figure 1, the embodiment of the invention one provides a kind of method of adjusting terminal transmit power, comprises the steps:
Step 11, when the user uses the terminal to communicate business, obtain said terminal and said user's the actual range and the power to be adjusted at said terminal.
Wherein, said communication service can comprise: voice calling service, video call service, data service or WIFI (wireless fidelity, wireless compatibility authentication) business etc.
The transmitting power of reality when the power to be adjusted at said terminal can carry out current communication service for said terminal, needed transmitting power in the time of also can being about to communicate business for said terminal.General, when the terminal communicated business, at first carried out alternately with the base station at this terminal, and then obtain its needed transmitting power by said base station.Concrete, message can be sent to said terminal in said base station, carries the transmitting power that said terminal needs in this message.
In the present embodiment, can utilize range sensor to obtain said terminal and said user's actual range.Wherein, said range sensor can be the range sensor of infrared proximity transducer or other types, does not do qualification at this.
Step 12, definite transmitting power threshold value corresponding with said actual range.
Wherein, said transmitting power threshold value representes when this terminal communicates business, if the actual transmitting power in this terminal surpasses said transmitting power threshold value, the electromagnetic wave of said terminal emission this moment produces harmful effect to the radiation meeting of human body to the health of human body.
Step 13, more said terminal wait to adjust power and said transmitting power threshold value.If the waiting of said terminal adjusted power greater than said transmitting power threshold value, then carry out step 14; If the power to be adjusted at said terminal is less than or equal to said transmitting power threshold value, then carry out step 15.
Step 14, the said terminal of adjustment wait that the size of adjusting power is said transmitting power threshold value, said terminal communicates business according to said transmitting power threshold value.
Step 15, said terminal communicate business according to power said to be adjusted.
Can find out by above description; The power to be adjusted at this terminal is set according to terminal and user's actual range; Thereby it is all minimum when making this terminal under various situation, communicate business to the radiation of human body; With respect to prior art, only come the maximum transmission power of limiting terminal more effectively to reduce the radiation of terminal to human body through power threshold.Therefore, utilize the technical scheme of the embodiment of the invention, reduced the radiation of terminal effectively human body.
As shown in Figure 2, the embodiment of the invention two provides a kind of method of adjusting terminal transmit power, comprises the steps:
Step 21, set up the mapping table of power and distance.
In the present embodiment, adjust said terminal and user's test distance L
i(i=1,2,3......n), and, said terminal obtains and said test distance L through being tested
iCorresponding test power C
i, and then according to said test distance L
iWith with said test distance L
iCorresponding test power C
iProcess said mapping table, as shown in table 1 below.Wherein, the distance when user and said terminal is test distance L
I-1-L
iThe time, said terminal utilizes said test power C
iNot only can normally communicate business, can also make the electromagnetic wave of its emission minimum the radiation of human body.Significantly, L
iMore little, C
iMore little.
Table 1
Concrete, the value of said n can be by the capacity decision of said terminal inner register.When setting up said mapping table, if the capacity of said terminal inner register is very little, what can the value of n be provided with is less; If the capacity of said terminal inner register is very big, what can the value of n be provided with is bigger.
In addition, corresponding different " mapping tables of power and distance " in dissimilar terminal.
Step 22, when the user uses the terminal to communicate business, obtain said terminal and said user's the actual range and the power to be adjusted at said terminal.
Wherein, step 22 can be with reference to the step 11 in the embodiment of the invention one.
Step 23, the definite transmitting power threshold value corresponding of inquiry said " mapping table of power and distance " of passing through with said actual range.
For example, when said actual range is L, said through inquiring about " mapping table of power and distance " can confirm that L is at (L
I-1, L
i], i.e. L
I-1＜L≤L
iIn the scope, corresponding with L so transmitting power threshold value is C
i
Step 24, more said terminal wait to adjust power and said transmitting power threshold value.If the waiting of said terminal adjusted power greater than said transmitting power threshold value, then carry out step 25; If the power to be adjusted at said terminal is less than or equal to said transmitting power threshold value, then carry out step 26.
Step 25, the said terminal of adjustment wait that the size of adjusting power is said transmitting power threshold value, said terminal communicates business according to said transmitting power threshold value.
Step 26, said terminal communicate business according to power said to be adjusted.
For example, the transmitting power of supposing this current reality in terminal is C
Now, can know that by step 23 said transmitting power threshold value is C
i, if C
Now＞C
i, the transmitting power with this current reality in terminal is C so
NowBe adjusted into C
i, at this moment, this terminal is with C
iCommunicate business, and this terminal emitted power is minimum to the radiation of human body.If C
Now≤C
i, the transmitting power that need not adjust this current reality in terminal so is C
Now, continue with C at this terminal
NowCommunicate business.
