Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is part of the embodiment of the present invention, rather than whole embodiments.Based on this hair Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made Example, belongs to the scope of protection of the invention.

Referring to Fig. 1, Fig. 1 is the flow chart for the antenna power adjusting method that one embodiment of the invention provides.Methods described should For mobile terminal, as shown in figure 1, the described method comprises the following steps：

The antenna transmitting electromagnetic energy of step 101, the control mobile terminal, and receive and reflected or worn by adjacent object Electromagnetic energy after the saturating adjacent object.

With the development of science and technology mobile terminal has had changed into an indispensable part in people's life now.But During using mobile terminal, especially when airtime communication is carried out using mobile terminal, the radiation of mobile terminal can User can be influenceed.And as long as mobile terminal is between start working condition, with base station and got in touch with, mobile terminal is just Emittance can be sent out.In order to reduce the radiation of mobile terminal to user's influence that may be present, movement is used in user When terminal, when especially carrying out airtime communication, generally require suitably to reduce the radiant power of mobile terminal.

Therefore, in this step, when user uses the mobile terminal, if object is close to mobile terminal, The mobile terminal can control in real time the mobile terminal antenna launch electromagnetic energy, and launch electromagnetic energy it Afterwards, the mobile terminal can be detected in real time, detect whether to receive by after mobile terminal transmitting, running into neighbouring thing Body, the electromagnetic energy either after the adjacent object is penetrated is reflected by the adjacent object.

Wherein, the adjacent object can be actively close to the object of the mobile terminal, hand, the face limb of such as user Body or the passive object close to the mobile terminal, as will be described mobile terminal be placed on desk or Bao Baonei When, the can such as desk or bag is considered the passive object close to the mobile terminal.

The parameter information for the electromagnetic energy that step 102, acquisition receive.

In the step, reflected when the mobile terminal is received due to running into the adjacent object by the adjacent object Either when the electromagnetic energy after penetrating the adjacent object, the mobile terminal can pass through the electromagnetism to receiving Energy is detected, to obtain the parameter information of the electromagnetic energy received.

Wherein, the parameter information of the electromagnetic energy received, can be after electromagnetic energy runs into the adjacent object, by institute State adjacent object reflection or penetrate the adjacent object, the parameter information of the electromagnetic energy after changing, wherein can So that including being reflected by the adjacent object either after the adjacent object is penetrated, the amplitude of electromagnetic energy and phase etc. are joined Number.

Step 103, based on the parameter information, determine the type of the adjacent object.

Electromagnetic energy is after running into different objects and transmitting occurs or penetrates object, because different objects is to electromagnetic energy The influence of amount is different, for example makes the loss of the energy amplitude size of electromagnetic energy different, with caused phase place change difference etc., because This, it is in this step, described after the mobile terminal gets the parameter information of the electromagnetic energy received by detection Mobile terminal can determine the adjacent object that runs into of electromagnetic energy of transmitting according to the different parameters in the parameter information Type.

Step 104, the type based on the adjacent object, judge whether to reduce the radiant power of mobile terminal, sentenced Disconnected result.

In the step, after the mobile terminal determines the type for the adjacent object that electromagnetic energy runs into, to lower pair The possible influence of health or harm, the mobile terminal, to be judged, can be sentenced according to the type of the adjacent object The disconnected radiant power for whether needing to reduce mobile terminal, and obtain judged result.

For example, such as when the mobile terminal is placed on wooden desk, the mobile terminal can determine Object close to mobile terminal is wooden plane, and like this, mobile terminal, which can consider, need not reduce radiant power；Instead It, if user needs to use the mobile terminal to be conversed, hand-held mobile terminal can pass through inspection close to head, mobile terminal When surveying the parameter information to determine close to head of the mobile terminal for human body, the mobile terminal can reduces radiation work( Rate, to lower the influence of the possibility of Radiation On Human body and potential hazard.

If the instruction of step 105, the judged result reduces the radiant power of mobile terminal, control in the mobile terminal Antenna reduces transmission power.

In the step, when the mobile terminal is according to the type of the adjacent object, obtained judged result instruction is to need When reducing the radiant power of mobile terminal, the mobile terminal can control the antenna in the mobile terminal, to drop The power of low antenna, so as to reduce the radiant power of the mobile terminal.

Because absorption of the human body to emittance has standard regulation, it is necessary to meet absorption rate (Specific Absorption Rate, abbreviation SAR), it is therefore, mobile whole being reduced by reducing the transmission power of antenna in mobile terminal When the radiant power at end, at least need that the radiant power for meeting SAR standards for the radiant power of mobile terminal can be reduced to Value.Preferably, present embodiment, can select to be to be reduced to the antenna radiated power of mobile terminal to meet SAR statutory standards Performance number.

Due to the type of antenna and the difference of performance, and the contribution to the radiant power of mobile terminal is different, if so The value of a certain size is reduced for the radiant power of a certain mobile terminal, then the transmission power that different antennas needs reduce is past Toward being different, need exist for being set according to specific mobile terminal, therefore do not do any restriction herein.

In the embodiment of the present invention, above-mentioned mobile terminal can with it is any for example：Mobile phone, tablet personal computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital Assistant, abbreviation PDA), mobile Internet access device (Mobile Internet Device, MID) or wearable device The mobile terminal of (Wearable Device) etc..

Antenna power adjusting method provided in an embodiment of the present invention, the antenna of the mobile terminal is controlled to launch electromagnetic energy Amount, and receive the electromagnetic energy after being reflected or being penetrated the adjacent object by adjacent object；Obtain the electromagnetic energy received Parameter information；Based on the parameter information, the type of the adjacent object is determined；Based on the type of the adjacent object, sentence The disconnected radiant power for whether reducing mobile terminal, obtains judged result；If the judged result instruction reduces the spoke of mobile terminal Power is penetrated, then controls the antenna in the mobile terminal to reduce transmission power.So, mobile terminal can be by launching electromagnetic energy Amount, and after receiving and running into object, the electromagnetic energy that is reflected by the object or penetrates after object, so as to detect the electromagnetic energy received The parameter information of amount, to determine the type of object, and according to the type of object, judge whether to need the spoke for reducing mobile terminal Power is penetrated, whether have object close to mobile terminal, and can also detect that the thing close to mobile terminal if can not only detect The type of body, so as to avoid existing mobile terminal because object close to when, the type close to object can not be detected, cause to judge by accident The problem of breaking and causing the power for reducing mobile terminal by mistake, therefore the present invention can improve the wireless communication experience of user.

Referring to Fig. 2, Fig. 2 is the flow chart for the antenna power adjusting method that another embodiment of the present invention provides, such as Fig. 2 institutes Show, the described method comprises the following steps：

The antenna transmitting electromagnetic energy of step 201, the control mobile terminal, and receive and reflected or worn by adjacent object Electromagnetic energy after the saturating adjacent object.

With the development of science and technology mobile terminal has had changed into an indispensable part in people's life now.But During using mobile terminal, especially when airtime communication is carried out using mobile terminal, the radiation of mobile terminal can User can be influenceed.And as long as mobile terminal is between start working condition, with base station and got in touch with, mobile terminal is just Emittance can be sent out at moment.In order to reduce the radiation of mobile terminal to user's influence that may be present, make in user When with mobile terminal, when especially carrying out airtime communication, generally require suitably to reduce the radiation of mobile terminal.

The parameter information for the electromagnetic energy that step 202, acquisition receive.

Wherein, the parameter information of the electromagnetic energy received, can be after electromagnetic energy runs into the adjacent object, by institute State adjacent object reflection or penetrate the adjacent object, the parameter information of the electromagnetic energy after changing, wherein can So that including being reflected by the adjacent object either after the adjacent object is penetrated, the phase of electromagnetic energy and amplitude etc. are joined Number.

Step 203, based on the parameter information, determine the type of the adjacent object.

Step 204, the type based on the adjacent object, judge whether to reduce the radiant power of mobile terminal, sentenced Disconnected result.

If step 205, the mobile terminal include at least two antennas, if judged result instruction reduces mobile terminal Radiant power, from least two antenna selection need reduce transmission power target antenna；Reduce the target day The transmission power of line.

In general, multiple antennas are respectively provided with mobile terminal, such as Bluetooth antenna, communication antenna, wireless network connection antenna Deng therefore, if the mobile terminal includes at least two antennas, in this step, when the mobile terminal bag When including at least two antennas, if the mobile terminal is judging whether to need to drop according to the type of the adjacent object When the radiation of low mobile terminal, obtained judged result is indicated if being the radiant power for needing reduction mobile terminal, that Whole antennas at least two antenna need not be carried out reduction transmission power by the mobile terminal, but can be first Selected from least two antenna in mobile terminal, select the target antenna for needing to reduce radiant power, so The transmission power of the target antenna is reduced afterwards, so as to reduce the radiant power of the mobile terminal.

Furthermore the target antenna, an antenna can be referred to or refer to two or more antennas.Such as such as There are three antennas in fruit mobile terminal, by detection, it is necessary to when reducing the radiant power of mobile terminal, only reduce in three antennas An antenna transmission power when, although the radiant power of mobile terminal can be reduced, the function of this antenna can be influenceed, And when selecting to be reduced the transmission power of this antenna and another antenna, the radiant power of mobile terminal can be met The requirement of reduction amplitude, but also do not influence each antenna and realize respective function, in this manner it is possible to by this antenna with it is another Individual antenna is as target antenna.The example above is only to illustrate that the target antenna can not do any limit with more than one antenna It is fixed.

Due to the type of antenna and the difference of performance, and the contribution to the radiant power of mobile terminal is different, if so The value of a certain size is reduced for the radiant power of a certain mobile terminal, then the transmission power that different antennas needs reduce is past Toward being also different, need exist for being set according to specific mobile terminal, therefore do not do any restriction herein.

Wherein, need to reduce the target antenna of transmission power from the middle selection of at least two antenna, can be basis The position of each antenna at least two antenna selects or according at least two antenna, each The factors such as the function and characteristic (such as transmission power characteristic) of antenna select, and can also be the different conditions according to mobile terminal Or when different service conditions, the working condition of different antennae selects.

For example, for example mobile terminal includes Bluetooth antenna, for realizing the signal of communication antenna with base station communication And for wireless network connection wireless network connect antenna when, in general, the position of different antennas on mobile terminals Also it is different, than if any at the top of mobile terminal, some is in the bottom of mobile terminal, when user is led to using mobile terminal During words, the top of mobile terminal often opposing floor portion closer to the head of user, so, it is logical carrying out call using mobile terminal When letter, the transmission power of the antenna positioned at the top of mobile terminal can be reduced with prioritizing selection, to reduce mobile terminal Radiant power；For another example, when user is conversed using mobile terminal, in order to ensure the signal of communication day for realizing communication The steady operation of line, it is impossible to reduce the power of communication information antenna, now, it is possible to from Bluetooth antenna and for wireless network Selected in the wireless network connection antenna of connection, also, use that may for data network during due to being communicated is minimum, Therefore can select to reduce the transmission power that wireless network connects antenna, to reduce the integral radiation power of mobile terminal.It is above-mentioned It is merely illustrative of, does not do any restriction.

Need what is illustrated, step 205 is interchangeable, i.e., step 205 can be understood as in the embodiment shown in Fig. 1 The restriction of step 105, but in the embodiment of the present invention, step 105 is not limited to the embodiment of step 205, can also pass through The embodiment for reducing the transmission power of default antenna realizes that is, step 201 could alternatively be the hair for reducing default antenna Penetrate power or replace with feature in step 105.

Optionally, step 203 includes：

Obtain the amplitude information in the parameter information；When calculating the amplitude information with mobile terminal transmitting electromagnetic energy Transmitting amplitude the first difference；The first corresponding relation based on default Magnitude Difference and object type, it is determined that with described The type of the adjacent object corresponding to one difference.

In the step, when the mobile terminal receive due to run into adjacent object and reflected by the adjacent object or The electromagnetic energy after the adjacent object is penetrated, and the mobile terminal gets parameter letter from the electromagnetic energy received After breath, the mobile terminal can obtain the amplitude information of the electromagnetic energy received, Ran Housuo from the parameter information The transmitting amplitude that mobile terminal is stated when the amplitude information can be launched into electromagnetic energy with mobile terminal is calculated, and passes through meter The first difference between transmitting amplitude when drawing amplitude information and mobile terminal the transmitting electromagnetic energy is calculated, it is then, described Mobile terminal can be according to good in advance statistics and be stored in the first corresponding of the Magnitude Difference in mobile terminal and object type Relation, run into determining the electromagnetic energy received, the type of the adjacent object corresponding with first difference.

Wherein, transmitting amplitude during mobile terminal transmitting electromagnetic energy, it is also believed that being the electromagnetism of mobile terminal transmitting Energy is propagated in free space, transmission amplitude when not running into object and producing change.

Wherein, transmitter, phase during mobile terminal transmitting electromagnetic energy, it is also believed that being the electromagnetism of mobile terminal transmitting Energy is propagated in free space, is not run into object and is produced propagation phase when passing change.

Preferably, in present embodiment, between transmitter, phase when being the calculating phase information and transmitting electromagnetic energy Difference, as the type fixed condition, but be not limited thereto really for determining the adjacent object, in other embodiments, than During if desired for the judgement or selection for having more precision, other calculations can also be used, the adjacent object is determined to obtain Type fixed condition really, do not do any restriction herein.

For example, in other embodiments, in order to improve the accuracy of judgement, can also be divided by multiple antennas After not detecting each spontaneous emission, the parameter information of respective electromagnetic energy is received again, and each obtain according to the multiple antenna Parameter information in phase information, to determine the type of adjacent object, and if adjacent object that multiple antennas determine Type is identical, or more than a number of antenna determine result show adjacent object type it is identical, then can with This more accurately determines the type of adjacent object, to improve detection accuracy.

Optionally, if the mobile terminal includes at least two antennas, step 202 includes：

Obtain the parameter information of the electromagnetic energy that first antenna receives at least two antenna.

In general, multiple antennas are respectively provided with mobile terminal, such as Bluetooth antenna, signal of communication antenna, wireless network connection Antenna etc., therefore, if the mobile terminal includes at least two antennas, in this step, the mobile terminal Antenna at least two antenna is controlled launches electromagnetic energy, and can be first day at least two antenna After line receives the electromagnetic energy after being reflected or being penetrated the adjacent object by the adjacent object, the mobile terminal can To obtain the parameter information for the electromagnetic energy that the first antenna receives.

Wherein, the electromagnetic energy that the first antenna receives is that the second antenna is launched at least two antenna, is worn Electromagnetic energy after the saturating adjacent object.

Optionally, step 203 includes：

It is described mobile whole after the mobile terminal is getting the parameter information of the first antenna in the step End can extract the amplitude information or phase information of the electromagnetic energy received from the parameter information, then, according to institute State amplitude information or phase information, come the second antenna for being calculated in the first antenna and at least two antenna it Between real-time Transmission parameter, after obtaining the real-time Transmission parameter, the mobile terminal can by the real-time Transmission parameter, Compared with the configured transmission of baseline between the first antenna and second antenna, and obtained by calculating described The 3rd difference between real-time Transmission parameter and the configured transmission of baseline, and after the 3rd difference is obtained, the shifting Dynamic terminal can be according to good and the configured transmission difference being stored in mobile terminal and the 3rd pair of object type in advance statistics It should be related to, be run into determining the electromagnetic energy received, the type of the adjacent object corresponding with the 3rd difference.

Wherein, the configured transmission of the baseline can be the electromagnetic energy by the second antenna transmitting of mobile terminal certainly By being propagated in space, when not running into object and producing change, the first antenna receives the configured transmission of electromagnetic energy.

Preferably, in present embodiment, it is to calculate difference between the real-time Transmission parameter and the configured transmission of baseline, makees To determine the type fixed condition, but be not limited thereto really of the adjacent object, in other embodiments, for example need When the judgement or selection of more precision, other calculations can also be used, to obtain the type for determining the adjacent object Condition is determined, does not do any restriction herein.

For example, in other embodiments, in order to improve the accuracy of judgement, can also be divided by multiple antennas The parameter information of the electromagnetic energy from other antennas Jian Ce be respectively received, and each obtained according to the multiple antenna Real-time Transmission parameter in parameter information, to determine the type of adjacent object, and if the adjacent object that multiple antennas determine Type it is identical, or more than a number of antenna determine result show adjacent object type it is identical, then can The type of adjacent object is more accurately determined with this, to improve detection accuracy.

Optionally, described the step of selection needs to reduce the target antenna of transmission power from least two antenna, Including：
