When the terminal is in use for communication or surfing the internet and is in contact with the human body of a user, due to the emission of electromagnetic waves, the radiated energy can not only cause the temperature rise of the human body, but also produce other physiological influences, namely electromagnetic wave absorption damage, under the interaction of the electromagnetic waves and human body cells. All body parts of a user human body are lossy media, an electromagnetic wave signal generated by a terminal forms current in the human body after passing through the body parts and organs, part of the electromagnetic wave energy signal is absorbed, and the electromagnetic power absorbed by the human tissue of unit mass or the energy increment is absorbed by a time derivative of the mass increment with given density and volume, namely, the specific absorption rate SAR is expressed by the following formula:

In some embodiments, the network mode detection unit 206 is connected with the adaptive SAR reduction control unit 205. The network mode detection unit 206 may obtain the current SAR reduction operating frequency band, channel, and network mode of the terminal, such as network coexistence information, wireless network performance information, specific absorption rate safety standard information, and antenna power information.

Since the SAR reduction parameter adjustment is strongly related to the operator information, the regulatory standards of different operators are not uniform, and the test distances of different operators are not uniform, if a set of SAR reduction parameters are built in each mobile phone, the sensing distance is fixed, and adaptive adjustment and control cannot be performed according to the specific absorption rate safety standard information of the operator network, which may result in no pertinence on power backoff in the SAR reduction process, the present embodiment performs an adaptive SAR reduction adjustment mechanism based on the network mode, so that it is possible to detect different cellular system modes, wireless communication modes, and the like, and also detect the current operator type information, and the subsequent adaptive adjustment may perform mapping adjustment control according to the above parameters, such as network coexistence information, wireless network performance information, specific absorption rate safety standard information, and antenna power information.

The network mode detection unit 206 firstly determines whether the terminal is in the SAR operating mode, secondly identifies whether the current network mode is LTE, WCDMA, NR mode, wifi2.4g/5G connection mode or hotspot mode, and can capture the reported information through the radio frequency module on the terminal for identification.

Meanwhile, the current operator type is also identified as FCC, CE or Japan, korea, china, australian Electricity, etc., wherein the identification is carried out through reporting information of software versions or card information, and different operator types correspond to different specific absorption rate safety standard information.

The parameters of the network mode detection are network information, server information and cell information reported by each operator, the information is received by a mobile phone antenna, frequency division is carried out by a radio frequency front end, filtering is carried out, frequency reduction is carried out by a radio frequency main chip after amplification, demodulation is carried out, the information is transmitted to a baseband chip for processing, the baseband chip analyzes wireless information reported by a modem side, and a specific LOGMASK information keyword is captured and analyzed to match which network type of the operator of the current network. Meanwhile, by capturing key parameters under each network system and reported information of the network and the wireless module, whether the current network system is a single network system or a concurrent network working mode can be detected, if the current network system is in the concurrent network working mode, network coexistence information in the concurrent network, such as LTE-NR, LTE-WIFI, NR-NR, NR-WIFI and the like, is obtained, and wireless network performance information, antenna power information and the like can be measured through the module.

102, acquiring target SAR influence parameters according to the influence degree of each SAR influence parameter on the SAR value, and acquiring a specific absorption rate adjustment mode matched with the target SAR influence parameters according to the matching relation between the preset SAR influence parameters and the specific absorption rate adjustment mode.

In some embodiments, the electronic device may obtain one or more SAR influence parameters as target SAR influence parameters from SAR influence parameters such as human-computer distance information, human-computer contact human body part information, network coexistence information, wireless network performance information, specific absorption rate safety standard information, and antenna power information, and adaptively push a specific absorption rate adjustment mode according to a matching relationship between the target SAR influence parameters and the specific absorption rate adjustment mode.

In some embodiments, the weight may be used as the influence degree according to the current weight of each SAR influence parameter, and then the target SAR influence parameter is determined according to different weights, and corresponding adjustment is performed by matching different specific absorption rate adjustment modes.

In other embodiments, when the SAR influence parameter meets a preset condition, the SAR influence parameter meeting the preset condition is used as a target specific absorption rate adjustment mode, wherein the influence degree of the SAR influence parameter meeting the preset condition on the SAR value is higher than the influence degree of the SAR influence parameter not meeting the preset condition on the SAR value.

It should be noted that the above manner of obtaining the target SAR influence parameter according to the influence degree of each SAR influence parameter on the SAR value is only an example, and in the practical application process, the method is not limited to this, in this embodiment, each SAR influence parameter is comprehensively considered, and an adjustment manner is determined in this way to perform SAR reduction processing, so that the method is suitable for SAR reduction processing in different scenes, so that the SAR reduction processing has a higher pertinence, and the health safety of the user can be practically protected.

The adjustment method of the present embodiment includes any one of the following items and combinations thereof: the method includes adjusting modes such as a network mode matching adjusting mode, a distance dynamic power adjusting mode, a wireless performance closed-loop SAR reducing adjusting mode, a concurrent mode selection SAR reducing adjusting mode, a human body part induction SAR reducing unit, a dynamic SAR reducing path adjusting unit and the like, but is not limited to the above. The adjusting units corresponding to the adjusting modes can be referred to as shown in fig. 2.

The self-adaptive SAR reduction control module reduces the SAR value according to the algorithm of capturing and analyzing the network and SAR reduction influence parameters, and combining the SAR influence parameters such as man-machine distance information, specific absorption rate safety standard information of operators, antenna power information, wireless network performance information, network coexistence information, man-machine contact human body part information and the like, namely combining different SAR influence parameters to carry out different adjustments.

The parameter storage unit 204 shown in fig. 2 is connected to the adaptive SAR reduction control unit 205, and the parameter storage unit 204 can be used for storing each parameter that needs to be called. The parameters to be called include mapping parameter values of the above adjustment modes, such as SAR value models at different distances under a network parameter SAR model, wireless signal parameter values, concurrent model set values, SAR value parameter model values of human body parts, and SAR value models under different paths. Distance model values of network parameters, such as SAR index parameter values under each network system, each frequency band, each distance and power. Wireless performance parameter values, such as uplink and downlink throughput and error rate values of the terminal in the NR mode, and default radio frequency performance values under different scheduling parameters, such as EVM, ACLR, RSRP, and estimated sensitivity values, modulation coefficients, data stream numbers, and the like. The parameter storage module further contains concurrent model values, such as different radio parameter values and SAR values in NR and LTE set subset mode, or index parameter values in dynamic power sharing mode.

Exemplary, SAR-affecting parameters include: the adaptive SAR reduction control module 205 is responsible for selecting a specific absorption rate adjustment mode, for example, human-computer distance information, human-computer contact human body part information, network coexistence information, wireless network performance information, specific absorption rate safety standard information, and antenna power information. The specific absorption rate adjustment modes correspond to the 6 specific absorption rate adjustment units shown in fig. 2, and each of the 6 specific absorption rate adjustment units has its own matched parameter characteristics, such as a network mode matching adjustment unit 207, a distance dynamic power adjustment unit 208, a wireless performance closed-loop SAR reduction adjustment unit 209, a concurrent mode selection SAR reduction adjustment unit 210, a human body part induction SAR reduction adjustment unit 211, and a dynamic SAR reduction path adjustment unit 212.

In this embodiment, the current network parameters detected by the network mode detection unit 206, the human body part information detected by the human body part identification unit 202 and the human-machine distance information calculated by the distance calculation unit 203 are combined, and parameter change values before and after the change are compared.

The SAR influence degree can be expressed as the influence of the current SAR influence parameter on the SAR value, and the larger the influence on the SAR value, the higher the SAR influence degree.

In some embodiments, the target SAR impact parameter comprises at least specific absorption rate safety criterion information if the specific absorption rate safety criterion information changes; if the man-machine distance is within a preset range, the target SAR influence parameters at least comprise man-machine distance information; if the human body part contacted by the man-machine changes, the target SAR influence parameters at least comprise human body part information contacted by the man-machine; if at least two networks are connected simultaneously, the target SAR influence parameters at least comprise network coexistence information; if the wireless network performance is lower than a first preset threshold, the target SAR influence parameter at least comprises: wireless network performance information; if the currently used antenna SAR value is higher than a second preset threshold, the target SAR influence parameters at least comprise: antenna power information. In another embodiment, one or more SAR influence parameters with a larger influence degree may be preferentially selected as the target SAR influence parameters according to the influence degree.

Exemplarily, if the influence degree is higher than the specific absorption rate safety standard information of the operator of the current network, such as the special distance of the SAR test and the standard information related to the threshold, the network mode matching adjustment mode corresponding to the specific absorption rate safety standard information is preferentially invoked; if the current human-computer distance is determined to be far or close according to the human-computer distance information, namely the human-body distance information is used as a target SAR influence parameter, the distance dynamic power adjustment is preferably called; if the current call quality is influenced according to the wireless network performance information, or the current call quality is in a weak signal condition, namely the wireless network performance information is used as a target SAR influence parameter, a wireless performance closed-loop SAR adjusting mode is preferably called, if the SAR exceeds the standard in the coexistence mode of 2/3/4/5G and WIFI at present is detected, namely the network coexistence information is the target SAR influence parameter, the wireless performance closed-loop SAR adjusting mode is preferably called, and if the current call contact part is changed according to the human-computer contact human body part information, namely the human-computer contact human body part information, the human body part induction-reduction SAR adjusting mode in the human body part induction-reduction SAR adjusting unit 211 is preferably called.

It should be mentioned that the above adjusting modes may be adjusted one by one, or may be combined two by two, or more combinations are used together until the requirements of network performance and SAR reduction are met, especially under the condition that the influence degrees of the relevant SAR influencing parameters are relatively close and are not very different, for example: the SAR influence parameters all meet preset conditions, and a plurality of adjusting modes can be combined in pairs.

In some embodiments, if the target SAR influence parameter includes a plurality of SAR influence parameters, the specific absorption rate adjustment modes matched with the SAR influence parameters in the target SAR influence parameter may be obtained, and the adjustment weights corresponding to the specific absorption rate adjustment modes may be obtained according to the influence degrees of the SAR influence parameters in the target SAR influence parameter. In this embodiment, a plurality of specific absorption rate adjustment modes are obtained for cooperative adjustment, and the adjustment weight may be obtained by referring to the influence degree, for example, the larger the influence degree is, the more the power back-off value is adjusted by using the specific absorption rate adjustment mode is.

Step 103 may be performed after obtaining the matched specific absorption rate adjustment mode.

And 103, adjusting the current specific absorption rate to the target specific absorption rate according to the matched specific absorption rate adjusting mode.

The target specific absorption rate may be a specific absorption rate preset in the device and meeting a certain safety standard, may also be a target specific absorption rate determined by specific absorption rate safety standard information of the current network, and may also be a specific absorption rate lower than a certain safety standard.

In some embodiments, if the target specific absorption rate SAR affects a parameter, the matching specific absorption rate adjustment mode is a network mode matching adjustment mode, and in the network mode matching adjustment mode, a power backoff value corresponding to specific absorption rate safety standard information may be acquired according to the specific absorption rate safety standard information of the current network; the specific absorption rate is adjusted according to the power back-off value. The corresponding functional unit is the network pattern matching adjustment unit 207 in fig. 2. A network mode matching adjustment unit 207 connected to the adaptive SAR reduction control unit 205, configured to perform SAR reduction adjustment based on the specific absorption rate safety standard information of the current network operator, and detect the safety standard information of the current network, such as FCC, CE, and the like, to determine different power backoff values.

In the embodiment, it is considered that if SAR adjustment is reduced, only safety standard information of a certain operator can be targeted, if FCC regulation adjustment is met, CE regulation adjustment cannot be met, chinese safety standard information is met, FCC safety standard cannot be met, the adjustment mode is single, and if power is reduced according to the strictest requirement, so that each standard requirement is met, power reduction is excessive to cause reduction of wireless performance, so that the embodiment can avoid reduction of wireless performance caused by excessive reduction of power as much as possible under the condition that safety standard requirements are met.

In some embodiments, if the target SAR impacts the parameter, the method includes: the matched specific absorption rate adjustment mode is a distance dynamic power adjustment mode according to the man-machine distance information, and a power backspacing value can be obtained according to the man-machine distance information in the distance dynamic power adjustment mode; wherein the human-computer distance and the power backoff value are in positive correlation; and adjusting the current specific absorption rate to the target specific absorption rate according to the power back-off value. The distance dynamic power adjustment manner corresponds to the distance dynamic power adjustment unit 208.

And the distance dynamic power adjusting unit 208 is connected to the adaptive SAR reduction control module 205, and is used for adjusting SAR reduction parameters sensed at different distances.

Compared with the SAR reduction adjustment, a fixed distance parameter is set to trigger SAR reduction treatment, if the SAR reduction is set to 10mm, the SAR reduction is triggered to 5mm, the SAR reduction is triggered to 0mm and the like, so that the SAR reduction cannot be triggered when the set distance is not met, for example, the SAR reduction sensor sesor sets the SAR reduction distance to be a fixed distance such as 5mm, the distance requirement is not met, if the man-machine distance is 10mm, the SAR reduction cannot be triggered, and further, the power cannot be dynamically adjusted according to different requirements.

For example: in an LTE B1 frequency band, a 10mm power back-off value is tested to be 3dB, so that the requirement of 1.6w/kg on SAR value threshold is met, and if the distance of human-computer contact is 5mm, the original 3dB back-off value cannot meet the requirement, for example, SAR back-off is reserved with a certain margin, if the SAR specified threshold is 1.6w/kg, and when the test meets the required back-off value of 3dB, the SAR value is 1.0w/kg, namely, the back-off threshold margin of 0.6w/kg exists. Therefore, the SAR value of 1.4w/kg is needed, namely the power back-off is 2dB, and the power back-off can be dynamically adjusted by a dynamic adjusting mode based on the human body distance information in the embodiment.

It should be mentioned that, if the human body distance information is adjusted in cooperation with the security standard information in the current network in this embodiment, different requirements for the human-machine distance under different security standards can be considered, so that the adjustment is more accurate, the SAR value can be reduced more practically, and the signal quality is ensured.

In some embodiments, if the target SAR impact parameter includes: the human body part information of man-machine contact, then the adjustment mode of matching includes: a distance dynamic power adjusting mode, wherein a power backspacing value matched with the human body part information can be obtained in the distance dynamic power adjusting mode; adjusting the specific absorption rate according to the matched power back-off value. The dynamic range power adjustment manner corresponds to the dynamic range power adjustment unit 208 in fig. 2, and the dynamic range power adjustment unit 208 is connected to the adaptive SAR reduction control module 205.

Specifically, the human body part refers to a part of the human body that may be contacted by the terminal, such as the left head, the right head, the ear, the mouth, the chin, the left hand, the right hand, the wrist, the left chest of the upper body pocket, the waist corresponding to the left and right trousers pockets, the hip corresponding to the trousers rear pocket, the foot, the ankle, and the like. The SAR absorption values of different parts are different, so that the damage to human bodies is different.

For example, the dynamic distance power adjusting unit 208 may first detect a human body part of a corresponding user close to the terminal during a current call or during a use process, search different calculation models for different parts, and perform different power backoff SAR operations. The human body part detection method comprises the following steps: the method comprises the steps of scanning a three-dimensional face model or face head texture through a 3D structure optical module or a front camera on a terminal, judging whether the three-dimensional face model or the face head texture is left head, right head, ear, mouth and chin or detecting whether the three-dimensional face model or the face head texture is left hand or right hand through holding point detection or pressure detection on the upper edge of the terminal. Because the dielectric constants of different substances are different, the charge feedback values under direct contact are also different, and the fact that the left chest of the upper body pocket is close to the mobile phone or the fact that the hip or the waist corresponding to the trousers pocket is close to the mobile phone can be detected and judged by detecting the difference between the fact that the mobile phone is close to the jacket and the different cloth of the trousers.

Compared with the situation that if the terminal detects that the user approaches, the SAR reduction power is started, the power is backed off, and false triggering may be caused by approach of other objects except the user, the SAR reduction processing can be performed based on the human body part information by detecting the human body part information in contact with the human body, and the situation of false triggering caused by approach of other objects except the user is avoided. Compared with the approach of a user, the power back-off value tested by using the same model, namely the human body part is not distinguished, so that the power back-off value is insufficient, for example, the back-off value for the part a is not suitable for the part B, or the power back-off value is too much, for example, the power back-off value is based on the part a, while the SAR value of the actual part B is much smaller, and the back-off is based on the part a, so that excessive back-off of power is caused, and further, the emission performance is reduced.

In some embodiments, if the SAR impact parameter comprises: and in the wireless performance closed-loop SAR adjustment mode, if the wireless network performance is lower than a preset value, acquiring the power which can be increased by the wireless network according to the current specific absorption rate and a target specific absorption rate, if the wireless network performance after the power is increased is lower than the preset value, switching the antenna currently used by the wireless network to a target antenna, and if the wireless network performance after the wireless network performance is switched to the target antenna is lower than the preset value, sending prompt information for instructing a user to keep the man-machine distance. The wireless network performance information of this embodiment may include: uplink and downlink call quality, uploading and downloading throughput rate, wireless performance of the wireless terminal in the self-space and left and right hands and the like. Standard information of the current network operator can be obtained to obtain the target specific absorption rate.

The adjustment mode of the wireless performance closed-loop SAR reduction corresponds to the adjustment unit 209 of the wireless performance closed-loop SAR reduction, and the adjustment unit 209 of the wireless performance closed-loop SAR reduction is connected with the adaptive SAR reduction control unit 205. The radio performance closed-loop SAR reduction adjustment unit 209 is configured to reduce SAR adjustment based on radio performance detection.

Illustratively, wireless network performance detection, such as a stuck detection mechanism and a throughput threshold detection mechanism, are set on an electronic device, and a wireless performance power determination mechanism is set and determined at the same time, that is, in the working process, when uplink stuck or uplink rate reduction is detected, it is determined whether the current power is limited, that is, whether the limitation is introduced by SAR reduction, and if so, the problem is improved by two strategies.

Strategy 1: and raising the SAR power limit value to the operator SAR value or the limit threshold value required by the certification.

Strategy 2: when the raised power reaches the SAR value limit, an upper antenna switching mechanism and a lower antenna switching mechanism are started, so that the power is raised, and the requirement of the SAR value can be met.

Strategy 3: if the strategy 1 and the strategy 2 are invalid, a distance prompting mechanism is started to indicate the holding posture of the user and keep away from the human body until the SAR value distance requirement is met.

Compared with direct power backoff directly based on a trigger distance, the problem that excessive power backoff causes uplink calling jamming or throughput reduction is solved, and the problem that the uplink calling jamming or throughput reduction is caused by excessive power backoff is also avoided under the condition that the SAR value is ensured to meet the requirement based on the consideration of wireless performance when the SAR value is adjusted, so that the power backoff meets the SAR reduction requirement and also meets the use requirement of the wireless performance.

In some embodiments, if the target SAR affects the parameter, it includes: if the network coexists information, the matched adjusting mode is a concurrent mode selective SAR reduction adjusting mode, and a total power backspacing value is obtained in the concurrent mode selective SAR reduction adjusting mode; allocating power back-off values to the networks according to the network performance requirements of the networks in the network coexistence information; wherein, the sum of the power back-off values allocated to each network is equal to the total power back-off value; and adjusting the current specific absorption rate to the target specific absorption rate according to the power back-off value allocated to each network.

The concurrent mode selective SAR reduction adjustment mode corresponds to the concurrent mode selective SAR reduction adjustment unit 210, and the concurrent mode selective SAR reduction adjustment unit 210 is connected to the adaptive SAR reduction control unit 205 and is configured to match SAR reduction adjustment based on the concurrent mode priority.

Network coexistence refers to a concurrent operation state of a network used by an electronic device, for example, a concurrent operation state of a combination of LTE-NR, LTE and WIFI connection, WCDMA and WIFI connection, NR and WIFI connection, LTE and WIFI hotspot, WCDMA and WIFI hotspot, NR and WIFI hotspot, WCDMA and NR, and the like in the electronic device.

Illustratively, referring to table three, the two systems of the concurrency mentioned above, i.e. the networks are referred to as a and B,

aiming at the unconfirmability of the power reduction, the work flow of the concurrent mode intelligent selection SAR reduction adjusting module is as follows:

the power back-offs for a and B are divided into several subsets, as shown in table four below:

watch four

Collection	A power backoff	B power backoff
			Set 1	4	0
Set 2	3	1
			Set 3	2	2
Set 4	1	3
			Set 5	0	4

Whether SAR exceeds the standard or not is detected, network characteristics such as signal intensity, signal-to-noise ratio, power and the like of A and B in a current concurrent working mode are detected preferentially in a concurrent working mode with coexisting networks, namely current service system characteristics such as SA, NSA, a hotspot mode and the like, and a descending combination with the smallest influence is judged and selected by judging the strength of the network characteristics of the A and B, the priority of the service system and the ratio of conversation or data performance descending after power is reduced. If the uplink signal of the current A is detected to be weak, the concurrent SAR value cannot be reduced by reducing the power of the A, and at this time, the mode of the set 5 is selected to reduce the power. Similarly, if it is detected that the uplink signal of the current B is already weak, the concurrent SAR value cannot be reduced by reducing the power of B, at this time, the mode of the set 1 is selected to reduce the power, and if both a and B can be reduced, the mode of any one of the sets 2 to 4 is selected in real time by detecting the network performance of the current a and B.

In addition, considering that when a and B are concurrently located, the antennas corresponding to a and B are distributed differently on the terminal, and the positions close to the human body are also different, if a and B are simultaneously operated, the antenna corresponding to a is located at the top of the mobile phone, the antenna corresponding to B is located at the top of the mobile phone, and the top receiver of the mobile phone is close during the current call, that is, a is close to and B is far from, then it is ineffective to reduce the power of B, and a set with much reduced power, such as set 1, needs to be selected.

Compared with a randomly selected network for power backoff, for example, the power of a is reduced independently, the power of B is reduced independently, or the powers of a and B are reduced simultaneously, so that the requirement of a combined SAR value is met, for example, in a scenario where NR and WIFI concurrently operate, when SAR exceeds a standard, NR power is returned from 24dBm to 20dbm independently, SAR may return to a target requirement, or NR power keeps 24dBm unchanged, WIFI power is returned from 16dBm to 12dbm, SAR may return to a target requirement, or NR power is reduced to 22dbm, WIFI is reduced to 14dbm, SAR may return to a target requirement, and randomness is strong.

In some embodiments, if the target specific absorption rate SAR affects a parameter, it includes: the matched specific absorption rate adjusting mode is a dynamic SAR reducing path adjusting mode, and in the dynamic SAR reducing path adjusting mode, an antenna meeting the target specific absorption rate is determined according to the antenna power information; the antenna currently in use is switched to the antenna that satisfies the target specific absorption rate. The dynamic power adjustment method corresponds to the dynamic SAR reduction path adjustment unit 212.

The dynamic SAR path adjustment unit 212 is connected to the adaptive SAR reduction control module 205, and is configured to perform SAR reduction adjustment based on the antenna path.

Exemplarily, in a 5G terminal, there are typically 4 × 4mimo four paths for NR. Through adding 3P3T,4P4T, DPDT switch etc. on each route, cascade together between each route, through SRS switching path promptly, realize reducing SAR and adjust, because the difference of each radio frequency conduction path and antenna, power and antenna efficiency on different radio frequencies and antenna paths are different, the corresponding SAR value is different, through switching radio frequency path and antenna, can switch the route that the SAR value is high to the route that the SAR value is low going. The power collection of different antennas can directly collect the SRS feedback signal, judge the SRS power on the corresponding antenna under the current network and system, and compare with the SAR value model, thereby selecting a path with small switched SAR value.

And based on the principle that the SAR values of antennas at different positions are different, when a user body approaches a terminal, if the SAR value of the antenna in the C area is high, the TX transmission of the antenna can be switched to the position with the low SAR value through multi-path switching, and the antenna is switched to a non-SAR value sensitive area and part by detecting the body part contacted by the user and the antenna part close to a mobile phone.

In some embodiments, if the target SAR influence parameter includes a plurality of influence parameters, the current specific absorption rate may be adjusted to the target specific absorption rate according to the adjustment weight corresponding to each specific absorption rate adjustment manner and each specific absorption rate adjustment manner.

In some embodiments, after the current specific absorption rate is adjusted to the target specific absorption rate according to the matched specific absorption rate adjustment mode, whether the performance of the wireless network is lower than a first preset threshold value or not can be detected, and if the performance of the wireless network is lower than the first preset threshold value, the specific absorption rate adjustment mode matched with the SAR influence parameter representing the network characteristics is obtained; and adjusting according to the specific absorption rate adjusting mode matched with the SAR influence parameters representing the network characteristics until the wireless network performance reaches the first preset threshold.

For example, the SAR impact parameter characterizing the network of the present embodiment may include: wireless network performance information, antenna power information, network coexistence information, and the like. If the current wireless network performance is lower than the first preset threshold value due to the adjustment of the SAR value, the wireless network performance can be ensured by switching antennas, adjusting the power distribution value of each network in the coexisting network, or prompting a user to keep a human-computer distance and the like, so that the communication quality can be ensured under the condition that the SAR value meets the health requirement of the user.

The SAR adjustment is reduced based on a mechanism of self-adaptive adjustment control, the power control and the SAR can be suitable for different scenes, the SAR adjustment mode is more flexible and effective, different application scenes of a user are fitted, the personal safety of the user is practically protected, the emission performance limit is improved, different scenes can be met, the SAR threshold requirements of different modes and different distances under combination can be met, the energy efficiency problem of SAR adjustment can be solved, the electromagnetic radiation safety of a communication terminal is improved, and the current communication quality can be ensured.
