Embodiment 1

[0021] refer to figure 1 , shows a flow chart of the steps of a method for reducing the SAR value in Embodiment 1 of the present invention.

[0022] The method for reducing the SAR value provided by the embodiments of the present invention includes the following steps:

[0023] Step 101: the mobile terminal obtains the number of transmitters currently in working state and the transmission power of each transmitter in working state.

[0024] The SAR value is the specific absorption rate, which is the energy (watts) of electromagnetic radiation absorbed by each kilogram of human tissue when it is averaged over any 6 minutes. Taking mobile phone radiation as an example, SAR refers to the rate at which radiation is absorbed by the soft tissues of the head. The lower the SAR value, the less radiation is absorbed by the brain.

[0025] In different working modes of the mobile terminal, the number of transmitters in the working state is different. For example, a mobile terminal in...

Embodiment 2

[0033] refer to figure 2 , shows a flow chart of the steps of a method for reducing the SAR value in Embodiment 2 of the present invention.

[0034] The method for reducing the SAR value provided by the embodiments of the present invention includes the following steps:

[0035] Step 201: the mobile terminal acquires the number of transmitters currently in working state and the transmission power of each transmitter in working state.

[0036] In different working modes of the mobile terminal, the number of transmitters in the working state is different. For example, a mobile terminal integrates Bluetooth, Wi-Fi, high-speed data network, and NFC (Near Field Communication, short-range wireless communication). In the data transmission mode, the number of transmitters in the working state is 1 or 2, and in the mode of using high-speed data network while answering the phone, the number of transmitters in the working state is 3 or 4 .

[0037] Step 202: When the number of transm...

Embodiment 3

[0043] refer to Figure 4 , shows a flow chart of the steps of a method for reducing the SAR value in Embodiment 3 of the present invention.

[0044] The method for reducing the SAR value provided by the embodiments of the present invention includes the following steps:

[0045] Step 301: the mobile terminal acquires the number of transmitters currently in working state and the transmission power of each transmitter in working state.

[0046] In different working modes of the mobile terminal, the number of transmitters in the working state is different. For example, a mobile terminal integrates Bluetooth, Wi-Fi, high-speed data network, and NFC (Near Field Communication, short-range wireless communication). In the data transmission mode, the number of transmitters in the working state is 1 or 2, and in the mode of using high-speed data network while answering the phone, the number of transmitters in the working state is 3 or 4 .

Abstract

The present invention provides a method for reducing the SAR value and a mobile terminal. The method includes: obtaining the number of transmitters currently in working state and the transmission power of each transmitter in working state; Adjust the positions of the transmitters in the working state, or adjust the transmission power of the transmitters in the working state, so as to reduce the SAR value of the mobile terminal, and can achieve the two maximum SAR values ​​when there are multiple transmitters. The distance between two transmitters is the farthest, so as to weaken the superposition effect produced by two transmitters transmitting at the same time. In addition, when there are multiple transmitters transmitting at the same time, by reducing the transmission power of each transmitter, multiple transmitters can be weakened. The superposition effect generated by simultaneous transmission of transmitters reduces potential risks to human safety and ensures communication quality.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for reducing the SAR value and a mobile terminal. Background technique [0002] With the rapid development of wireless communication technology, especially with the upcoming commercial use of 5G, wireless communication systems have more and more functions. At this time, there are often situations where multiple transmitters work at the same time. , the SAR value generated by each transmitter will cause harm to the human body, wherein the SAR value is the electromagnetic radiation energy absorbed by a unit mass of material per unit time. [0003] In the prior art, there are two main ways to reduce SAR: one is to directly reduce the maximum transmission power of each transmitter, thereby reducing the SAR value of each transmitter, which will reduce the quality of wireless communication, thus affecting the user experience. experience; the second is to reduce the t...
