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.
the electronic device joint specific absorption rate adjusting method, device and electronic device according to the embodiments of the present application are described below with reference to the drawings.
In the application scenario of the 5G NSA technology, the transmitting antenna of the 5G NR and the transmitting antenna of the LTE transmit signals at the same time, electromagnetic radiation generated by the transmitting antenna of the 5G NR and the transmitting antenna of the LTE is superposed, and the combined SAR value after superposition is higher than that when any antenna works independently, so that the problem that the SAR value exceeds the standard is caused.
In the related art, the joint SAR value in the 5G NSA scenario is reduced by directly limiting the transmission power of the 5G NR transmit antenna and the LTE transmit antenna. Specifically, on the premise of meeting the requirement of a joint SAR value, a group of values a and b are determined through testing for different frequency band combinations of 5G NR and LTE and different antenna combinations, where a and b are the maximum transmission powers of the 5G NR antenna and LTE antenna when meeting the requirement of the joint SAR value, so that the requirement of the joint SAR value can be met when the transmission power of the 5G NR transmission antenna does not exceed a and the transmission power of the LTE transmission antenna does not exceed b. For example, assuming that 5G NR is transmitted from the antenna 1 and LTE is transmitted from the antenna 2, when it is determined through testing that the maximum transmission power of the antenna 1 is a and the maximum transmission power of the antenna 2 is b, the joint SAR value requirement is satisfied, and in a 5G NSA scenario, when the transmission power of the antenna 1 does not exceed a and the transmission power of the antenna 2 does not exceed b, the joint SAR requirement may be satisfied.
However, in order to ensure the communication quality of each communication mode, in the prior art, the maximum transmission power of each transmission antenna is usually reduced to reduce the joint SAR value, so that the joint SAR value does not exceed the standard. That is, in the 5G NSA scenario, the maximum transmit power a of the 5G NR transmit antenna is less than the maximum transmit power a of the 5G NR transmit antenna when operating alone, for example, a is 23dBm, and a is 20dBm, and the maximum transmit power B of the LTE transmit antenna is less than the maximum transmit power B of the LTE transmit antenna when operating alone. In practical use, when the transmission power of the 5G NR transmitting antenna is less than a, even if the transmission power of the LTE transmitting antenna is greater than B, for example, the transmission power is B, the joint SAR value requirement may be satisfied, and vice versa, however, since the prior art limits the maximum transmission power of the 5G NR to a and limits the maximum transmission power of the LTE to B, the maximum transmission power that can be achieved by the 5G NR and the LTE is limited, and the uplink communication capability of the 5G NSA is reduced.
In order to solve the above problems, the present application provides an electronic device joint specific absorption rate adjustment method, which determines a joint SAR value of an electronic device by obtaining a target working frequency band and a target transmission frequency of the electronic device in a preset networking mode, and reduces the transmission power of at least one target antenna when the joint SAR value is greater than a preset threshold, so as to implement real-time monitoring of the joint SAR value, and implement dynamic adjustment of the transmission power to ensure that the joint SAR value does not exceed a standard, and the method of the present application does not directly limit the maximum transmission power of 5G NR and LTE, so that the electronic device can use a transmission power greater than the maximum transmission power defined in the prior art in some scenes, thereby improving the uplink communication capability.
Fig. 1 is a flowchart illustrating a method for adjusting a specific absorption rate of an electronic device combination according to an embodiment of the present disclosure, where the method can be applied to an electronic device with a communication function, such as a smart phone and a tablet computer. As shown in fig. 1, the electronic device combined specific absorption rate adjustment method may include the following steps:
Step 101, detecting whether the electronic device works in a preset networking mode, wherein at least two transmitting antennas work simultaneously in the preset networking mode.
The preset networking mode may be preset, and at least two transmitting antennas operate simultaneously in the preset networking mode, and the preset networking mode may include, but is not limited to: 5G NSA mode, 5G +2/3/4G mode in 5G SA scene, 5G +2/3/4G + WiFi/Bluetooth mode, etc.
In this embodiment, the electronic device may detect whether itself operates in the preset networking mode, for example, the electronic device may detect whether itself operates in the preset networking mode in real time or periodically.
Specifically, the electronic device may detect the network mode of the electronic device in the current working state by using a related technology, for example, the state of each transmitting antenna set in the electronic device may be detected, and when the transmitting antenna in the on state is detected, the current network mode of the electronic device may be determined. And then, comparing the detected network mode with a pre-stored preset networking mode, and if the detected network mode exists in the preset networking mode, determining that the electronic equipment currently works in the preset networking mode. For example, when the network mode detected by the electronic device is the 5G NSA mode, it may be determined that the electronic device currently operates in the preset networking mode, and in the 5G NSA mode, the transmitting antenna of the 5G NR and the transmitting antenna of the LTE operate simultaneously.
And 102, if yes, acquiring target working frequency bands and target transmitting powers of at least two target antennas corresponding to a preset networking mode.
In this embodiment, when it is detected that the electronic device currently operates in the preset networking mode, the target operating frequency bands and the target transmitting powers of at least two target antennas corresponding to the preset networking mode are further acquired; and if the electronic equipment is detected not to work in the preset networking model currently, keeping the current communication state of the electronic equipment.
It can be understood that when it is determined that the electronic device operates in the preset networking mode, at least two target antennas corresponding to the preset networking mode can be determined. For example, the electronic device currently operates in a 5G NSA mode, and the mode is a preset networking mode, and then it may be determined that the corresponding target antenna is a 5G NR antenna and an LTE antenna.
In this embodiment, different manners may be adopted to obtain the target operating frequency band corresponding to the target antenna.
As an example, the modem module corresponding to each target antenna may be used to monitor the radio frequency chip corresponding to each target antenna, obtain the operating frequency band and channel of each target antenna, and further determine the corresponding target operating frequency band.
As an example, working frequency bands of different Network modes corresponding to different operators may be stored in advance, and an operator to which a SIM card installed in an electronic device belongs may be determined according to a Mobile Country Code (MCC) and a Mobile Network Code (MNC), where the MCC has 3 bits in total and is used to uniquely identify a Country to which a Mobile subscriber belongs, for example, the MCC in china is 460, and the MCCs in the united states include 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. And then, the target working frequency band can be determined according to the determined operator and the target antenna by inquiring the prestored working frequency bands of different network modes corresponding to different operators.
In this embodiment, the target transmission power corresponding to the target antenna may be obtained by using a related technology, for example, the target transmission power may be read from a radio frequency chip corresponding to the target antenna, or the target transmission power of the target antenna may also be estimated according to the current reception power.
step 103, determining the current combined specific absorption rate of the electronic device according to the target working frequency bands and the target transmitting powers of the at least two target antennas.
In this embodiment, after the target operating frequency band and the target transmission power of the target antenna are determined, the current combined SAR value of the electronic device may be determined according to the target operating frequency band and the target transmission power.
As an example, for each working frequency band of each antenna, on the premise of meeting the requirement of the SAR value, the SAR values corresponding to different transmission powers may be tested in advance, and a corresponding relationship between different transmission powers and SAR values is established, and the corresponding relationship between different transmission powers and SAR values corresponding to each working frequency band of each antenna is stored in the electronic device, where the SAR values in the corresponding relationship all meet the SAR value standard. And then, after the target working frequency band of the target antenna is determined, determining a corresponding target corresponding relation according to the target working frequency band of the target antenna, further determining an SAR value according to the target transmitting power corresponding to the target antenna by inquiring the corresponding relation, and determining the current combined SAR value of the electronic equipment according to at least two determined SAR values.
As an example, for each operating frequency band of each antenna, on the premise of meeting the SAR value requirement, the SAR values corresponding to different transmission powers may be tested in advance, and a calculation formula of the SAR value and the transmission power may be fitted according to the test result, for example, the calculation formula may be represented as y ═ x0+ k x + c, where y denotes the SAR value, x denotes the transmit power, x denotes the power0and the basic transmitting power is represented and is a fixed value, and k and c are constants and can be calculated according to the test result. It can be understood that, for different antennas or different operating frequency bands, the SAR values corresponding to the same transmission power may be different, and thus the calculation formula obtained by fitting according to the test result is also different, which is the present inventionin the example, calculation formulas corresponding to the operating frequency bands of the antennas may be stored in advance. And then after the target working frequency band of the target antenna is determined, determining a corresponding target calculation formula according to the target working frequency band of the target antenna, substituting the target transmitting power corresponding to the target antenna into the target calculation formula to obtain a corresponding SRA value, and determining the current combined SAR value of the electronic equipment according to the at least two determined SAR values.
And 104, comparing the combined specific absorption rate with a preset threshold, and reducing the transmitting power of at least one target antenna if the combined 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 the joint SAR value is determined, the joint SAR value may be compared with a preset threshold, and when the joint SAR value is found to be greater than the preset threshold by comparison, the transmission power of at least one target antenna is reduced; and if the joint SAR value is not larger than the preset threshold value, keeping the current communication state of the electronic equipment.
As an example, when the obtained joint SAR value is greater than the preset threshold, the transmission power of each target antenna may be reduced simultaneously. For example, assuming that two target antennas are provided, namely a 5G NR antenna and an LTE antenna, the target transmission power of the 5G NR antenna is a1, and the target transmission power of the LTE antenna is b1, when the joint SAR value exceeds a preset threshold, the transmission powers of the 5G NR antenna and the LTE antenna may be simultaneously reduced, for example, the transmission power of the 5G NR antenna is reduced by a1 to a first preset value, and the transmission power of the LTE antenna is reduced by b1 to a second preset value, where the first preset value and the second preset value may be the same or different, which is not limited in this application.
as an example, when the obtained joint SAR value is greater than a preset threshold, the transmission power of only one target antenna may be reduced. Specifically, the target transmission power of each of the at least two target antennas may be compared, and the transmission power of the target antenna corresponding to the maximum target transmission power may be reduced by a preset value. For example, assuming that two target antennas are provided, namely a 5G NR antenna and an LTE antenna, the target transmission power of the 5G NR antenna is a1, and the target transmission power of the LTE antenna is b1, when the joint SAR value exceeds a preset threshold, the values of a1 and b1 may be compared, and if a1 is greater than b1, the transmission power of the 5G NR antenna is reduced from a1 to a preset value; if a1 is smaller than b1, reducing the transmitting power of the LTE antenna from b1 by a preset value; if a1 is equal to b1, the transmission power of the 5G NR antenna may be reduced from a1 by a preset value, or the transmission power of the LTE antenna may be reduced from b1 by a preset value.
When the electronic device runs different application programs, the distance between the user and the handheld electronic device and each part of the user is different, for example, when the user uses the electronic device to make a call, the electronic device is closer to the head of the user, and when the user uses the electronic device to watch videos and play games, the electronic device is closer to the limbs of the user. It can be understood that different parts of the body have different requirements for SRA values, and that the SAR values for the head are more stringent than for the limbs. Therefore, in this embodiment, in order to ensure the communication quality of the electronic device as much as possible, different SAR value requirements may be set for different human body parts, that is, different SAR value requirements may be set for different applications. Before comparing the joint SAR value with the preset threshold, a suitable preset threshold may be selected according to a current foreground application in the electronic device. Therefore, in this embodiment, before step 104, the following steps may be further included:
And determining a preset threshold according to the currently running foreground application of the electronic equipment.
Specifically, a corresponding technique may be adopted to obtain an 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.
Furthermore, after determining the application program running in the foreground, the application program can be applied according to the current foreground. And determining a corresponding preset threshold value. The SAR value requirement corresponding to the current foreground application can be determined by inquiring the mapping relation after the current foreground application is obtained, and the SAR value requirement is determined as a preset threshold value, so that the determined combined SAR value is compared with the preset threshold value to judge whether the transmitting power of the target antenna needs to be adjusted.
The preset threshold is determined according to the current foreground application of the electronic equipment, so that the flexible selection of the preset threshold is realized, the flexibility of the method is improved, and the communication quality of the electronic equipment is improved.
In the method for adjusting the joint specific absorption rate of the electronic device according to this embodiment, by detecting whether the electronic device operates in a preset networking mode, at least two transmitting antennas operate simultaneously in the preset networking mode, and when it is detected that the electronic device operates in the preset networking mode, a target operating frequency band and a target transmitting power of at least two target antennas corresponding to the preset networking mode are obtained, a current joint specific absorption rate of the electronic device is determined according to the target operating frequency band and the target transmitting power of the at least two target antennas, and then the joint specific absorption rate is compared with a preset threshold, and if it is known that the joint specific absorption rate is greater than the preset threshold, the transmitting power of the at least one target antenna is reduced. Therefore, the combined SAR value of the electronic equipment is determined by acquiring the target working frequency band and the target transmitting frequency of the electronic equipment in the preset networking mode, and the transmitting power of at least one target antenna is reduced when the combined SAR value is larger than the preset threshold value, so that the real-time monitoring of the combined SAR value is realized, the transmitting power is dynamically adjusted to ensure that the combined SAR value does not exceed the standard, and the influence of electromagnetic radiation on the human health is reduced.
In order to more clearly describe a specific implementation process of determining a current joint SAR value of an electronic device in the foregoing embodiment, an embodiment of the present application provides another electronic device joint specific absorption rate adjustment method, and fig. 2 is a flowchart of the electronic device joint specific absorption rate adjustment method provided in another embodiment of the present application.
As shown in fig. 2, the electronic device combined specific absorption rate adjustment method may include the following steps:
step 200, pre-establishing and storing a mapping relation between a plurality of transmitting powers and corresponding specific absorption rates for each working frequency band of each antenna in the electronic equipment.
at present, most electronic devices support multiple wireless communication modes such as cellular networks (i.e., 2G, 3G, 4G, and 5G networks), WiFi, bluetooth, and the like, and correspondingly, multiple antennas such as 2G, 3G, 4G, 5G, WiFi, bluetooth, and the like need to be arranged in the electronic devices, and each antenna has a different operating frequency band. In this embodiment, before the electronic device leaves the factory, a specific absorption rate test may be performed for each operating frequency band of each antenna in the electronic device.
Specifically, each antenna can be tested in sequence, during testing, the electronic device is controlled to work in different working frequency bands, for each working frequency band, the corresponding SAR value of the antenna is tested when the antenna works with different transmission power, for example, the test can be started from the minimum transmission power to obtain the corresponding SAR value, then the transmission power is sequentially increased according to a preset step length and the corresponding SAR value is obtained, when the SAR value exceeds the standard, the transmission power is slightly reduced until the SAR value is consistent with the standard value, and the maximum transmission power required by the SAR value is met when the antenna works in the current frequency band is obtained. And after the test is finished, establishing and storing a mapping relation between a plurality of transmitting powers and corresponding specific absorption rates when the antenna works in the working frequency band. The mapping relationship may be a corresponding relationship table, and the format of the corresponding relationship table may be as shown in table 1, or may be a calculation formula determined according to the test result, which is not limited in this application.
TABLE 1
Where, in table 1, P denotes the lowest transmission power, and P0 denotes the step size of increasing the transmission power.
After each antenna in the electronic device is tested, a mapping relation between the transmission power and the SAR value can be established according to the format of table 1, and the mapping relation is stored in the electronic device in advance.
It should be noted that, in order to determine the SAR value corresponding to the transmission power, the step length for adjusting the transmission power during the test may be set to be the same as the preset value for reducing the transmission power of at least one target antenna when the combined SAR value exceeds the standard.
In this embodiment, each working frequency band of each antenna is tested, and the maximum transmitting power required by the SAR value is not required to be combined and tested when two antennas work at most with the antennas in different frequency bands like the existing testing mode, in the existing testing scheme, when the antennas are more and the working frequency bands are more, the combination results are also many, so that the testing workload of the existing testing mode is very large, the testing is only performed when a single antenna works in different working frequency bands, and the testing workload is greatly reduced.
step 201, detecting whether the electronic device works in a preset networking mode, wherein at least two transmitting antennas work simultaneously in the preset networking mode.
step 202, if yes, obtaining target working frequency bands and target transmitting powers of at least two target antennas corresponding to a preset networking mode.
In this embodiment, for the description of step 201 to step 202, reference may be made to the description of step 101 to step 102 in the foregoing embodiment, and details are not described here again.
Step 203, determining a target mapping relation corresponding to the target working frequency bands according to the target working frequency bands of the at least two target antennas.
In this embodiment, after the target operating frequency bands and the target transmitting powers of the at least two target antennas are obtained, the corresponding target mapping relationship may be determined according to the target operating frequency band of each target antenna. The mapping relation between the transmitting power and the SRA value under different working frequency bands of different antennas is pre-stored in the electronic equipment, so that the corresponding target mapping relation can be determined according to the target working frequency band of the target antenna.
And 204, determining at least two target specific absorption rates corresponding to the target transmitting power according to the target mapping relation.
Taking the target mapping relation as the corresponding relation table of the transmitting power and the SAR value as an example, the target specific absorption rate corresponding to the target transmitting power can be determined by inquiring the corresponding relation table. The target specific absorption rates of the at least two target antennas can be determined by querying the corresponding target mapping relationships corresponding to the target transmission powers of the at least two target antennas.
Step 205, summing at least two target specific absorption rates to obtain a combined specific absorption rate.
In this embodiment, after the target specific absorption rate of each target antenna is determined, at least two target specific absorption rates may be summed to obtain a current combined SAR value of the electronic device.
And step 206, comparing the combined specific absorption rate with a preset threshold, and if the combined specific absorption rate is greater than the preset threshold, reducing the transmitting power of at least one target antenna.
In this embodiment, after the joint SAR value is determined, the joint SAR value is compared with a preset threshold, and if the obtained joint SAR value is greater than the preset threshold, the transmission power of at least one target antenna is reduced.
in the electronic device joint specific absorption rate adjustment method of this embodiment, mapping relationships between multiple transmission powers and corresponding specific absorption rates are pre-established and stored for each operating frequency band of each antenna in the electronic device, when joint specific absorption rates are determined, a target mapping relationship corresponding to a target operating frequency band is determined according to target operating frequency bands of at least two target antennas, at least two target specific absorption rates corresponding to target transmission powers are determined according to the target mapping relationship, and then, the at least two target specific absorption rates are summed and calculated to obtain the joint specific absorption rates, so that accuracy of obtaining the joint specific absorption rates is improved, and a condition is provided for judging whether the joint specific absorption rates meet a standard or not.
the radiation influence of the SAR value on the human body is generally related to the distance between the human body and the electronic device, and when the electronic device is close to the human body, for example, when a user uses the electronic device to perform voice call, the electronic device is generally close to the head of the user, and at this time, the SAR value has a greater radiation influence on the human body; when the electronic equipment is far away from the human body, the SAR value of the electronic equipment is slightly larger, and the SAR value cannot 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 this embodiment, before detecting whether the electronic device operates in the preset networking mode, the relative position between the electronic device and the user may be detected in real time, or the relative position between the electronic device and the user may be periodically detected, and then, according to the detected relative position between the electronic device and the user, whether the electronic device currently satisfies the specific absorption rate adjustment condition is determined. When the electronic equipment is determined to meet the specific absorption rate adjusting condition currently, whether the electronic equipment works in a preset networking mode is detected.
That is, before step 101 or step 201, the following steps may be further included:
And determining that the electronic equipment currently meets the specific absorption rate adjustment condition according to the relative position of the electronic equipment currently 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 by 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 at the relative position is smaller than or equal to a preset distance threshold value, judging that the specific absorption rate adjustment condition is currently met, and further detecting whether the electronic equipment works in a preset networking mode.
In this embodiment, before detecting whether the electronic device currently operates in the preset networking mode, whether the electronic device currently satisfies the specific absorption rate adjustment condition is determined according to a relative position between the electronic device and a user, and when it is determined that the electronic device currently satisfies the specific absorption rate adjustment condition, whether the electronic device operates in the preset networking mode is detected.
