FIG. 1 shows a schematic diagram of a control structure of actual transmit power of a mobile terminal in the prior art. As shown in Figure 1, in related technologies, the control of the transmit power of the mobile terminal is mainly through software control of radio frequency components, such as controlling the modem Modem or transceiver Transceiver chip, and finally changing the radio frequency parameters of the radio frequency front-end module to change the transmission purpose of power. The implementation process of this control method is relatively complicated, the cost is high, and the research and development period is long. In addition, various radio frequency components are prone to problems in the actual use process, and the reliability is not strong.

FIG. 2 shows a flow chart of a transmission power control method provided by an embodiment of the present application. The method of this embodiment can be executed by a transmission power control device, which can be implemented by means of hardware and/or software. The apparatus may be disposed inside the mobile terminal as a part of the mobile terminal. The mobile terminals described in the embodiments of the present application include devices such as mobile phones, tablet computers, or notebooks.

As shown in FIG. 2, the transmission power control method provided in this embodiment includes the following steps:

Step 101 , when it is detected that an actual transmit power reduction event is triggered, acquire a to-be-reduced amount of actual transmit power.

There are some application scenarios that do not require strong transmission power during the use of mobile terminals. For example, the users of mobile terminals are people who are sensitive to transmission signals, such as sick people, pregnant women, or children, and for example, users need to artificially make mobile terminals weak. Signal or noise scenarios (for example, when the user makes a call with the other party, he wants the other party to think that the user’s signal is not good; or, when the user receives a signal from someone else’s call, he intentionally blocks the transmission signal of the user’s mobile terminal , making it impossible or intermittent performance to search the network, and wanting the other party to be unable to make incoming calls; or, the receiving power of the mobile terminal is strong and does not require a large transmission power. In the above application scenarios, it is necessary to reduce the mobile terminal the actual transmit power.

Wherein, the transmission power of the mobile terminal refers to the power of the radio frequency signal output by the transmitter, and the actual transmission power refers to the transmission power of the mobile terminal, which is output to the outside of the mobile terminal housing after the antenna shield cover on the mobile terminal shields and attenuates a part of the radio frequency signal. The power of the actual RF signal. If no antenna shielding cover is set on the mobile terminal, it can be considered that the transmission power is the same as the actual transmission power. Wherein, the antenna shielding cover is arranged outside the circuit board of the mobile terminal to shield the antenna from transmitting signals.

Optionally, this step may include: when receiving an actual transmit power reduction instruction from the user, acquiring a to-be-reduced amount of the actual transmit power.

Generally, the receiving power of a mobile terminal is inversely proportional to the transmitting power. When the receiving power is weak, the transmitting power may be stronger, and the transmitting power needs to be reduced. Different terminal types have different received signal strengths. The following table shows the received power signals of various versions. Example of intensity:

Optionally, this step may include: when it is detected that the received power X is relatively weak within the set threshold range and the duration reaches the set time, automatically obtaining the amount to be reduced of the actual transmit power according to the received power. Wherein, the set threshold range may be X<A, and the value range of A may be -113dBm to -98dBm.

When receiving the actual transmission power reduction instruction of the user acting on the preset user interface of the touch screen, the actual transmission power to be reduced is obtained according to the actual transmission power reduction instruction, and correspondingly, after receiving the user’s actual transmission power reduction instruction The method may also include the following steps: when detecting the user's instruction to start the transmission power control application software on the mobile terminal, start the transmission power control application software and display the preset user interface.

The mobile terminal can also monitor the received power in real time, and when the received power is within the set threshold range and the duration reaches the set time, it will automatically obtain the amount to be reduced in the actual transmit power. Wherein, when the receiving power is within the set threshold range, it means that the mobile terminal is in strong receiving power and does not need a large actual transmitting power in the application scenario.

Optionally, when receiving the user's actual transmission power reduction instruction, acquiring the actual transmission power to be reduced includes: when receiving the user's actual transmission power reduction instruction, according to the actual transmission power reduction instruction corresponding to At least one of the user's touch trajectory, touch duration, and touch pressure is used to obtain a to-be-reduced amount of actual transmit power.

Exemplarily, different types of touch trajectories can be preset to correspond to different to-be-reduced amounts, for example, the to-be-reduced amount corresponding to a straight-line touch track is 1dBm, and the to-be-reduced amount corresponding to a circular closed touch track is 2dBm; The length setting of the control track corresponds to different amounts to be reduced, for example, every 1cm corresponds to a reduction amount of 1dBm. It can be set to correspond to a different amount of reduction according to the touch duration, for example, the amount to be reduced is 1dBm per second; it can also be set to correspond to a different amount of reduction according to the touch pressure, for example, the amount to be reduced is 1dBm per unit of pressure, Of course, different to-be-reduced amounts can also be set according to any combination of touch trajectory, touch duration, and touch pressure.

Optionally, when it is detected that the received power is within the set threshold range and the duration reaches the set time, automatically obtaining the amount to be reduced of the actual transmit power according to the received power includes: when the received power X is detected When it is within a set threshold range and the duration reaches the set time, the first amount to be reduced of the actual transmission power is automatically obtained according to the received power X; when it is detected that the received power X is within the second set threshold range and the duration When the set time is reached, a second to-be-reduced amount of the actual transmission power is automatically obtained according to the received power X; wherein, the first set range is smaller than the second set range, and the first to-be-reduced amount is less than The second to-be-reduced amount.

Wherein, the first set threshold range may be B<X<A, the first to-be-reduced amount may be 1dBm, the second set-threshold range may be X<B, and the second to-be-reduced amount It can be 2dBm-3dBm. Wherein, the value range of B is -120dBm to -106dBm. The reason for such setting is: the amount to be reduced of the actual transmit power can be more accurately determined according to the magnitude of the received power.

It should be noted that the set threshold range, the first set threshold range, the second set threshold range, the first to-be-reduced amount, and the second to-be-reduced amount given above are displayed by the 4G signal strength of the smart phone (public version ) as an example, it can be understood that the above-mentioned range parameters can be set correspondingly according to the signal strength of different versions, which is not limited in this embodiment.

Step 102: Determine the shielding information of the antenna shielding cover according to the amount to be reduced, and the antenna shielding cover is arranged outside the circuit board of the mobile terminal to shield the antenna from transmitting signals.

FIG. 3 shows a schematic structural diagram of the antenna shielding cover provided by the embodiment of the present application. As shown in FIG. 3 , the antenna shielding cover A can be arranged outside the circuit board of the mobile terminal P and inside the casing of the mobile terminal P, and the initial position of the antenna shielding cover A can be outside the antenna signal emission area B. The antenna shielding cover A can move toward the antenna signal emitting area B along the direction Z, so as to cover a part of the antenna emitting area and shield part of the antenna emitting area from transmitting signals. Among them, the antenna shielding cover can be made of metal materials, and different metal materials can be selected according to the needs of users for shielding effects. For example, copper or iron with strong shielding effect can be used for pregnant women, and aluminum with weaker shielding effect can be used for ordinary users. , the shape of the antenna shielding cover may be a rectangle, a disk sector, or an irregular shape, which is not limited in this embodiment.

Wherein, the shielding information of the antenna shielding cover may include a moving direction and a moving amount of the antenna shielding cover. Wherein, when the actual transmission power needs to be reduced, the moving direction is to move to the antenna transmission area. In addition, a preset correspondence table between the movement amount of the antenna shielding cover and the actual transmit power reduction amount can be preset, and correspondingly, the movement amount corresponding to the amount to be reduced can be searched from the preset correspondence table according to the amount to be reduced.

Step 103: Control the antenna shielding cover to shield the antenna transmission signal of a corresponding size according to the shielding information, so that the actual transmission power of the mobile terminal is reduced by the amount to be reduced.

Optionally, this step includes: using the programmable control motor of the mobile terminal according to the shielding information to control the antenna shielding cover to move to the antenna signal transmission area to cover the antenna signal transmission area of a corresponding size, so that the mobile terminal The actual transmit power of the device is reduced by the to-be-reduced amount.

The antenna shielding cover is driven to move accordingly by controlling the movement of the programmable control motor of the mobile terminal. Specifically, it can be: according to the shielding information, the programmable control motor of the mobile terminal is used to control the antenna shielding cover to the antenna signal transmission area. The movement of the size of the movement amount covers the antenna signal transmission area of a corresponding size, so that the actual transmission power of the mobile terminal is reduced by the to-be-reduced amount.

Optionally, the programmable control motor is a programmable control motor used by the mobile terminal to control the rotation of the rotating camera. The reason for such setting is to use the existing programmable control motor on the mobile terminal to control the movement of the antenna shielding cover, which can save costs.

Optionally, using the programmable control motor of the mobile terminal to control the antenna shielding cover to move to the antenna signal transmission area to cover the antenna signal transmission area of a corresponding size includes: using the programmable control motor of the mobile terminal to control The antenna shielding cover moves to the antenna setting area to cover the antenna signal transmission area of the corresponding size of the antenna setting area; and/or, the programmable control motor of the mobile terminal is used to control the antenna shielding cover to be set to the antenna belt The area is moved to cover the antenna signal transmission area corresponding to the size of the antenna band setting area.

At present, many mobile terminals such as mobile phones have metal casings. In order to transmit antenna signals, the casings are generally provided with white or other colored antenna strips for transmitting signals. The control method for reducing the actual transmission power provided by this embodiment can move the antenna shielding cover to the antenna installation area or to the antenna belt installation area. Its function is to attenuate the antenna transmission signal and reduce the actual transmission power of the mobile terminal. transmit power.

In the prior art, it is generally adopted to reduce the allowable maximum actual transmission power. For example, in the case that the maximum actual transmission power is 23dBm, the transmission power obtained in real time can be reduced by reducing the maximum actual transmission power to 20dBm. Exemplarily, for the real-time acquired transmission power of 18dBm, 19dBm, 20dBm, 21dBm, 22dBm and 23dBm, after adopting the transmission power control scheme in the prior art, the corresponding actual transmission power is 18dBm, 19dBm, 20dBm, 20dBm, 20dBm and 20dBm. Assuming that the amount to be reduced is 2dbm, then after adopting the transmission power control scheme provided by the embodiment of the present application, the corresponding actual transmission powers are 16dBm, 17dBm, 18dBm, 19dBm, 20dBm and 20dBm. That is, in the prior art, as long as the real-time transmission power is not greater than the maximum actual transmission power, the real-time transmission power is not reduced. When the real-time transmission power is greater than the maximum actual transmission power, the real-time transmission power is assigned the maximum actual transmission power, and this application is Regardless of the relationship between the real-time transmit power and the maximum actual transmit power, the real-time transmit power will be reduced by an amount to be reduced (for example, 5dBm). If the reduced real-time transmit power is greater than the maximum actual transmit power, the real-time transmit power will be assigned the maximum actual transmit power. transmit power.

The transmission power control method provided in this embodiment obtains the amount of the actual transmission power to be reduced when the actual transmission power reduction event is detected to be triggered, determines the shielding information of the antenna shielding cover according to the amount to be reduced, and controls the antenna based on the shielding information The shielding cover shields the antenna transmission signal of the corresponding size, and realizes that in the application scenario where the transmission power needs to be reduced, the antenna shielding cover is controlled by the software to shield a part of the antenna transmission signal, which reasonably reduces the actual transmission power of the mobile terminal. Since no mobile terminal is required The radio frequency components participate in it, so the implementation method is simple and easy to implement, and also saves the cost of reducing the actual transmission power of the mobile terminal, and improves the accuracy and reliability of reducing the actual transmission power of the mobile terminal.
