With the rapid development of electronic devices such as tablet computers and smart phones and mobile internet technologies, electronic devices become indispensable communication and internet access tools for people. However, the electronic device generates electromagnetic radiation during communication, and the electromagnetic radiation causes a certain degree of radiation to the human body.
In order to evaluate the degree of influence of electromagnetic radiation of electronic devices on human body, Specific Absorption Rate (SAR) is introduced. The SAR is also called as an electromagnetic wave absorption ratio and refers to a ratio of electromagnetic radiation absorbed by a human body, and the lower the SAR, the less the electromagnetic radiation is absorbed by the human body, and the smaller the degree of influence of the electromagnetic radiation of the electronic device on the human body. That is, the smaller the SAR value, the better.
Currently, in the related art, when the SAR value exceeds the general standard (the U.S. standard is 1.6W/kg, and the european standard is 2.0W/kg), the SAR value is generally reduced by reducing the transmission power. However, for the case where the transmitting antennas of the cellular network and the wireless network transmit signals simultaneously, the joint SAR value of the two needs to be controlled to comply with the common standard. When the combined SAR value exceeds the universal standard, if the SAR value is still reduced by reducing the transmission power, more power needs to be reduced compared with the case that the single SAR value exceeds the standard, thereby causing the communication quality to be reduced. Therefore, how to reduce the joint SAR value without affecting the communication quality becomes an urgent problem to be solved.

The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
In the description of the present application, it is to be understood that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
A method, an apparatus, an electronic device, and a storage medium for reducing a combined specific absorption rate according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for reducing a combined specific absorption rate according to an embodiment of the present application, where the method may be applied to an electronic device with a communication function, such as a smart phone, a tablet computer, and the like, where the electronic device includes a pair of cellular transmitting antennas and a pair of wireless transmitting antennas.
It should be noted that the present application does not limit the location of the pair of cellular transmitting antennas and the pair of wireless transmitting antennas in the electronic device.
As an example, taking the electronic device as a smart phone and the wireless network as a WLAN network as an example, as shown in fig. 2, a pair of cellular transmitting antennas may be respectively disposed at the upper left corner and the lower right corner of the smart phone, and a pair of wireless transmitting antennas may be respectively disposed at the upper right corner and the lower left corner of the smart phone. In fig. 2, the upper cellular antenna and the lower cellular antenna form a pair of cellular transmitting antennas, and when the smart phone transmits signals through the cellular network, only one of the upper cellular antenna and the lower cellular antenna transmits signals. The upper WLAN antenna and the lower WLAN antenna form a pair of wireless transmitting antennas, and when the smart phone works in a Single-Input Single-Output (SISO) mode, only one antenna of the upper WLAN antenna and the lower WLAN antenna transmits signals; when the smartphone operates in a multiple-Input multiple-Output (MIMO) mode, both the upper WLAN antenna and the lower WLAN antenna transmit signals. Of course, the pair of cellular transmitting antennas and the pair of wireless transmitting antennas may also be disposed at other positions of the smart phone, for example, the pair of cellular transmitting antennas is disposed at the upper left corner and the lower left corner of the smart phone, and the pair of wireless transmitting antennas is disposed at the upper right corner and the lower right corner of the smart phone; alternatively, a pair of cellular transmitting antennas may be disposed on the left and top edges of the smartphone, respectively, a pair of wireless transmitting antennas may be disposed on the bottom and right edges of the smartphone, respectively, and so on.
As shown in fig. 1, the method of reducing the combined specific absorption rate may comprise the steps of:
step 101, detecting whether a cellular network and a wireless network of an electronic device are in a transmitting state at the same time, and if so, acquiring a first working frequency band of the wireless network and a second working frequency band of the cellular network.
At present, the european CE certification newly introduces a management regulation of joint SAR, and requires joint testing of SAR values when a cellular network and a wireless network are concurrent, that is, when testing signals transmitted by the cellular network 2G, 3G, 4G, 5G simultaneously with WLAN or bluetooth, etc., the joint SAR values should meet the general standard (the U.S. standard is 1.6W/kg, and the european standard is 2.0W/kg).
With the development of electronic technology, electronic devices can now support both cellular networks (i.e., 2G, 3G, 4G, and 5G networks) and wireless networks to transmit signals simultaneously. For example, in the case where the electronic device turns on a cellular network and a Wi-Fi network, the user uses the cellular network when making a call, and the browser running in the background in the electronic device uses the Wi-Fi network. When the cellular network and the wireless network are in a transmitting state at the same time, the combined SAR value of the two may exceed a specified common standard, and thus be affected by electromagnetic radiation during use of the electronic device by the user.
In order to alleviate the situation that the combined SAR value exceeds the standard, in this embodiment, the network used by the electronic device may be detected, and when it is detected that the cellular network and the wireless network of the electronic device are in the transmitting state at the same time, the first operating frequency band of the wireless network and the second operating frequency band of the cellular network are further acquired.
As an example, the states of the cellular transmitting antennas of the cellular network and the wireless transmitting antennas of the wireless network may be detected, and when it is detected that one of the cellular transmitting antennas is in an on state and at least one of the wireless transmitting antennas is in an on state, it is determined that the cellular network and the wireless network are in a transmitting state at the same time.
Further, a first operating frequency band of the wireless network and a second operating frequency band of the cellular network may be obtained.
According to the mobile communication frequency division standard, different operators and different network systems use different network frequency bands, for example, the frequency bands used by the GSM900 system of the chinese mobile are uplink 890-909MHz and downlink 935-954 MHz; the frequency bands used by the GSM900 system of China Unicom are uplink 909-915MHz and downlink 954-960 MHz; the frequency bands used by the CDMA800 system of China telecom are uplink 825-835MHz and downlink 870-880 MHz; for FDD-LTE system, the frequency band used by China Unicom is uplink 1755 + 1765MHz, downlink 1850 + 1860MHz, the frequency band used by China Unicom is uplink 1765 + 1780MHz, and downlink 1860 + 1875 MHz; for a WLAN network, the working frequency band is 2400-2483.5 MHz; for bluetooth, the operating band is 5275 and 5850 MHz.
Thus, in this embodiment, when it is detected that the cellular network and the wireless network are in the transmitting state at the same time, the first operating frequency band of the wireless network and the second operating frequency band of the cellular network may be further determined. Specifically, when the wireless network is bluetooth, the first operating frequency band may be 5275-5850 MHz; when the wireless network is a WLAN network, the first operating frequency band may be determined to be 2400-2483.5 MHz. When the second operating frequency band of the cellular network is obtained, the operator to which the SIM card installed in the electronic device belongs may be obtained first, and then the second operating frequency band is determined.
For example, the operator to which the SIM card belongs may be determined according to a Mobile Country Code (MCC) and a Mobile Network Code (MNC). The number of MCCs is 3, which is used for uniquely identifying the country to which the mobile subscriber belongs, for example, the MCC in china is 460, and the MCCs in the united states are 310, 311 and 316; MNC is 2 in total, and china mobile uses 00, 02, 04 and 07, china unicom uses 01, 06 and 09, and china telecom uses 03, 05 and 11. Thus, the operator to which the SIM card belongs can be determined from the MCC + MNC. For example, 460+00 represents china movement. And then, the second working frequency band of the cellular network can be determined by inquiring the corresponding relation between the pre-stored operator and the working frequency band. For example, when a user uses the electronic device to make a call, if the SIM card installed in the electronic device is a GSM card of china mobile, the current cellular network access data of the electronic device is a 2G network of china mobile, so that it can be determined that the second operating frequency band is 890-909MHz and 935-954 MHz.
And 102, determining the combined specific absorption rate of the wireless network and the cellular network according to the first working frequency band and the second working frequency band.
In this embodiment, after the first operating frequency band of the wireless network and the second operating frequency band of the cellular network are determined, the combined specific absorption rate of the wireless network and the cellular network may be determined according to the first operating frequency band and the second operating frequency band.
For example, joint specific absorption rates of the electronic device operating in different first and second operating bands may be tested in advance, and a mapping relationship between each of the first and second operating bands and the corresponding joint specific absorption rate may be determined, and then after the first and second operating bands are determined, the corresponding joint specific absorption rate may be determined by querying the stored mapping relationship.
And 103, comparing the joint specific absorption rate with a preset threshold, and detecting a target network used by foreground application of the electronic equipment if the joint specific absorption rate is larger than the preset threshold.
The preset threshold value can be preset, and the preset threshold value is not greater than the general standard. For example, when using the European standard, the preset threshold should be set to not more than 2.0W/kg; when the us standard is used, the preset threshold should be set to not more than 1.6W/kg.
In this embodiment, after determining the joint specific absorption rate of the cellular network and the wireless network, the obtained joint specific absorption rate may be compared with a preset threshold, and if the joint specific absorption rate is greater than the preset threshold, the target network used by the foreground application of the electronic device is further detected.
Specifically, the related art may be first adopted to obtain the application currently running in the foreground in the electronic device.
As an example, the application running in the foreground may be determined according to a call parameter of ActivityLifecycle. For an application, when the activityllifecycle calls the parameter onResume (), it can be determined that the application is currently in a foreground running state.
As an example, if the name of the process in which the foreground Activity is located is the package name of the application, when the currently running application is obtained, the currently running application may be indirectly obtained by obtaining the process information.
After the foreground application is determined, the target network can be determined according to the network used by the foreground application. For example, when the foreground application is a phone call or a short message, the target network may be determined to be a cellular network; when the foreground application is an instant chat software, a video playing software and the like, the target network can be determined to be a WLAN network.
And 104, controlling the working states of the cellular transmitting antenna and the wireless transmitting antenna according to the types of the target network and the wireless network.
In this embodiment, after determining a target network used by a foreground application currently running in the electronic device, the operating states of the cellular transmitting antenna and the wireless transmitting antenna may be controlled according to the types of the target network and the wireless network.
Wherein, the types of the wireless network refer to SISO wireless network and MIMO wireless network.
Taking the example that the user uses the electronic device to make a call, the target network is a cellular network, and if the electronic device operates in the SISO wireless network, the wireless transmitting antenna currently in an operating state in the SISO wireless network may be turned off, and another wireless transmitting antenna may be enabled to transmit signals. For example, in fig. 2, if the currently operating upper WLAN antenna is used, the antenna may be turned off, the lower WLAN antenna may be set to the on state, and the lower WLAN antenna may transmit signals.
In one possible implementation manner of the embodiment of the present application, if the target network is a cellular network and the wireless network is a SISO wireless network, where the first wireless transmitting antenna or the second wireless transmitting antenna in the SISO wireless network operates, controlling the operating states of the cellular transmitting antenna and the wireless transmitting antenna according to the types of the target network and the wireless network includes: when the first wireless transmitting antenna works, the first wireless transmitting antenna is closed and the second wireless transmitting antenna is opened; or when the second wireless transmitting antenna works, the second wireless transmitting antenna is closed and the first wireless transmitting antenna is opened. Therefore, the normal work of the SISO wireless network is ensured, and the probability that the user suffers from electromagnetic radiation is reduced under the condition that the use experience of the user is not influenced.
In a possible implementation manner of the embodiment of the present application, if the target network is a cellular network and the wireless network is an MIMO wireless network, where a first wireless transmitting antenna and a second wireless transmitting antenna in the MIMO wireless network operate simultaneously, controlling operating states of the cellular transmitting antenna and the wireless transmitting antenna according to types of the target network and the wireless network includes: when the position of the honeycomb transmitting antenna in the working state is determined to be closest to the first wireless transmitting antenna, the first wireless transmitting antenna is closed; or when the position of the cellular transmitting antenna in the working state is determined to be closest to the second wireless transmitting antenna, the second wireless transmitting antenna is closed.
As an example, the position information of a pair of cellular transmitting antennas and a pair of wireless transmitting antennas in the electronic device may be stored in advance in the electronic device, when it is determined that the target network is a cellular network, the target cellular transmitting antenna in a transmitting state is further detected, the position information of the target cellular transmitting antenna and the position information of the wireless transmitting antenna are acquired, the position relationship between the pair of wireless transmitting antennas and the target cellular transmitting antenna is compared, a target wireless transmitting antenna (a first wireless transmitting antenna or a second wireless transmitting antenna) which is closer to the target cellular transmitting antenna is determined, and the target wireless transmitting antenna is turned off.
By closing the wireless transmitting antenna which is close to the cellular transmitting antenna in the working state in the MIMO wireless network, the combined SAR value is favorably reduced, so that the influence of electromagnetic radiation on a human body is reduced, and the human body safety is ensured.
In a possible implementation manner of the embodiment of the present application, if the target network is a wireless network, controlling the operating states of the cellular transmitting antenna and the wireless transmitting antenna according to the types of the target network and the wireless network includes: and when the wireless network is a SISO wireless network, closing the first cellular transmitting antenna in the current working state and opening the second cellular transmitting antenna. Taking fig. 2 as an example, assuming that the currently operating cellular transmitting antenna is the upper cellular antenna in fig. 2, the upper cellular antenna is turned off, and the lower cellular antenna is turned on, so that the lower cellular antenna transmits signals. Therefore, when the combined SAR value exceeds the universal standard, the honeycomb transmitting antenna is switched to transmit signals, the probability that the combined SAR value exceeds the standard can be reduced, and the risk that the human body suffers from electromagnetic radiation is reduced.
In a possible implementation manner of the embodiment of the present application, if the target network is a wireless network, controlling the operating states of the cellular transmitting antenna and the wireless transmitting antenna according to the types of the target network and the wireless network includes: and when the wireless network is an MIMO wireless network, closing the wireless transmitting antenna closest to the first cellular transmitting antenna in the working state.
In practical implementation, the position relationship between each wireless transmitting antenna and each cellular transmitting antenna may be stored in the electronic device in advance, and the wireless transmitting antenna closest to the first cellular transmitting antenna currently in the operating state may be determined by querying the position relationship.
Taking the electronic device shown in fig. 2 as an example, assuming that the first cellular transmitting antenna currently in the operating state is an upper cellular antenna, it can be seen from fig. 2 that the upper WLAN antenna is closer to the upper cellular antenna, the upper WLAN antenna is turned off, and only the lower WLAN antenna is left in the on state.
When the wireless network is an MIMO wireless network, the wireless transmitting antenna closest to the first cellular transmitting antenna in the working state is closed, so that the combined SAR value is favorably reduced, the influence of electromagnetic radiation on a human body is reduced, and the human body safety is ensured.
In the method for reducing the joint specific absorption rate of the embodiment, a pair of cellular transmitting antennas and a pair of wireless transmitting antennas are arranged in an electronic device, when it is detected that a cellular network and a wireless network of the electronic device are simultaneously in a transmitting state, a first working frequency band of the wireless network and a second working frequency band of the cellular network are obtained, the joint specific absorption rate of the wireless network and the cellular network is determined according to the first working frequency band and the second working frequency band, the joint specific absorption rate is compared with a preset threshold, when it is known that the joint specific absorption rate is greater than the preset threshold, a target network used by a foreground application of the electronic device is detected, and the working states of the cellular transmitting antennas and the wireless transmitting antennas are controlled according to the types of the target network and the wireless network. Therefore, when the joint specific absorption rate exceeds a preset threshold value, the working states of the cellular antenna and the wireless transmitting antenna are controlled according to the types of the target network and the wireless network, the purpose of reducing the joint specific absorption rate by adjusting the working states of the transmitting antenna is achieved, the transmitting power does not need to be reduced, the communication performance of the electronic equipment is ensured, and the influence of electromagnetic radiation on human health is reduced while the use experience of a user is not influenced.
To more clearly illustrate a specific implementation process of determining a combined specific absorption rate of a wireless network and a cellular network according to a first operating frequency band and a second operating frequency band in the foregoing embodiments, an embodiment of the present application provides another method for reducing the combined specific absorption rate, and fig. 3 is a flowchart of another method for reducing the combined specific absorption rate provided by the embodiment of the present application.
As shown in fig. 3, based on the embodiment shown in fig. 1, step 102 may include the following steps:
step 201, querying a preset corresponding relationship between a working frequency band and a specific absorption rate, obtaining a first specific absorption rate corresponding to the first working frequency band, and obtaining a second specific absorption rate corresponding to the second working frequency band.
The preset corresponding relation between the working frequency band and the specific absorption rate can be obtained through testing in advance and stored in the electronic equipment.
As an example, the specific absorption rate test may be performed on the electronic device before the electronic device is shipped. Specifically, the electronic device may be controlled to operate in different operating frequency bands, the specific absorption rate of the electronic device when the electronic device operates in the operating frequency band is tested for each operating frequency band, the corresponding relationship between the operating frequency band and the specific absorption rate is recorded, and after the specific absorption rate test of each operating frequency band is completed, the obtained corresponding relationship between each operating frequency band and the corresponding specific absorption rate is stored in the electronic device.
In this embodiment, after the first operating frequency band of the wireless network and the second operating frequency band of the cellular network are obtained, by querying a preset corresponding relationship between the operating frequency band and the specific absorption rate, the first specific absorption rate corresponding to the first operating frequency band and the second specific absorption rate corresponding to the second operating frequency band can be obtained.
Step 202, determining a combined specific absorption rate based on the first specific absorption rate and the second specific absorption rate.
For example, the obtained first specific absorption rate and the obtained second specific absorption rate may be summed, and the sum may be used as the combined specific absorption rate.
In the method for reducing the combined specific absorption rate of the embodiment, the first specific absorption rate corresponding to the first working frequency band and the second specific absorption rate corresponding to the second working frequency band are determined by querying the preset corresponding relationship between the working frequency bands and the specific absorption rates, and then the combined specific absorption rate is determined according to the first specific absorption rate and the second specific absorption rate, so that the accuracy of obtaining the combined specific absorption rate is improved, and a condition is provided for judging whether the combined specific absorption rate meets the standard.
The radiation influence of the combined specific absorption rate on the human body is generally related to the distance between the human body and the electronic equipment, and when the electronic equipment is closer to the human body, for example, when a user uses the electronic equipment to carry out voice call, the electronic equipment is generally closer to the head of the user, and at the moment, the combined specific absorption rate has a greater radiation influence on the human body; when the electronic device is far away from the human body, even if the combined specific absorption rate of the electronic device is slightly larger, the combined specific absorption rate may not cause radiation influence on the human body. Therefore, the relative position between the electronic device and the user can be used as a condition for determining whether to adjust the specific absorption rate of the electronic device.
Therefore, in a possible implementation manner of the embodiment of the application, before detecting whether the cellular network and the wireless network of the electronic device are in the transmitting state at the same time, it may be determined whether the electronic device currently satisfies the specific absorption rate adjustment condition according to the current relative position of the electronic device and the user.
As an example, a distance sensor, a gravity sensor, an infrared sensor, or the like may be built in the electronic device, and a relative position between the electronic device and the user may be detected in real time or periodically by using the built-in sensor of the electronic device, where the relative position may be a distance between the electronic device and the user. And then, comparing the detected relative position with a preset distance threshold value to judge whether the electronic equipment meets the specific absorption rate adjustment condition currently. If the distance displayed by the relative position is larger than a preset distance threshold, judging that the specific absorption rate adjusting condition is not met currently; and if the distance displayed by the relative position is less than or equal to a preset distance threshold value, judging that the specific absorption rate adjustment condition is met currently.
When the electronic equipment is determined to meet the specific absorption rate adjustment condition currently, whether a cellular network and a wireless network of the electronic equipment are in a transmitting state at the same time or not is continuously detected; if the fact that the electronic equipment does not meet the specific absorption rate adjusting condition currently is determined, the relative position of the electronic equipment and the user currently is obtained again, whether the electronic equipment meets the specific absorption rate adjusting condition or not is continuously judged, and therefore the combined specific absorption rate of the electronic equipment is adjusted timely.
According to the method, whether the cellular network and the wireless network of the electronic equipment are in the transmitting state at the same time or not is determined when the electronic equipment meets the specific absorption rate adjustment condition currently according to the relative position of the electronic equipment and a user, and the transmitting state of the cellular network and the wireless network is not detected when the electronic equipment does not meet the specific absorption rate adjustment condition, so that the power consumption caused by the operation of reducing the joint specific absorption rate when the electronic equipment is far away from a human body is effectively avoided, the power consumption is saved, and the cruising ability of the electronic equipment is improved.
