The embodiment provides a method for adjusting antenna transmitting power, as shown in fig. 1, the method includes:
s100, determining a specific absorption rate test scene of the terminal equipment.
Specifically, the radiation influence of the Specific Absorption Rate (SAR) on the human body is generally related to the distance between the human body and the terminal device, and when the terminal device is close to the human body, for example, when the user uses the terminal device to perform a voice call, the terminal device is generally close to the head of the user, and at this time, the specific absorption rate has a greater radiation influence on the human body; when the terminal device is far from the human body, the specific absorption rate of the terminal device may not cause radiation influence on the human body even if the specific absorption rate of the terminal device is slightly large. Accordingly, according to the relative distance between the terminal device and the user and/or the operation state, as a judging condition for judging whether the specific absorption rate needs to be adjusted, correspondingly, in practical application, the determining the specific absorption rate test scenario of the terminal device specifically includes:
s101, acquiring an operation state of terminal equipment, wherein the operation state comprises a motion state, a call state, a network state and an object approaching and keeping away state;
s102, determining a specific absorption rate test scene of the terminal equipment according to the running state.
In this embodiment, the motion state of the terminal may include a call state and a non-call state, the network state may include a hot spot state and a cellular network state, the hot spot state may include on and off, the cellular network state may include on and off, and the object approaching and distant state includes an approaching state and a distant state. Therefore, in this embodiment, the operation state of the terminal device may include various situations, for example, non-call, hot spot closing, cellular network closing, and proximity state; the method can also be in a non-call state, a hot spot closing state, a cellular network closing state and a far-away state; the method can also be in a call, hot spot closing, cellular network opening and approaching state; and the method can also be in a call, in a hot spot closed state, in a cellular network open state and in a far-away state. Therefore, different situations may correspond to different specific absorption rate test scenarios, for example, when the call state is in a call, and the corresponding specific absorption rate test scenario is a header SAR test scenario; when the call state is in a non-call state, the corresponding specific absorption rate test scene is a body SAR test scene. In practical application, in order to enable the terminal device to meet the SAR index of the antenna in different specific absorption rate test scenes, the maximum value of the transmitting power of the antenna of the terminal device needs to be adjusted in real time.
S200, determining the position information of the terminal equipment.
Specifically, since the testing methods and limiting requirements of the specific absorption rate of different countries and different regions are different, if the specific absorption rate of the same terminal device is not easy to achieve the requirements of the different countries and regions at the same time if the same terminal device is shipped in the different countries and regions, in one implementation manner, the specific absorption rate corresponding to the different countries and regions can be determined by positioning the terminal device and then according to the positioned position information, so that the power of the terminal device can be adjusted according to the specific absorption rate corresponding to the different countries and regions, and the terminal device can meet the SAR index requirements of the antenna in the different countries and regions.
In this embodiment, the location information may be obtained by locating through a locating system such as GPS, beidou, galileo, glonass, etc., and accurate information of the terminal device may be obtained through the locating system, in practical application, the terminal device may be located in real time, or may be located at preset intervals, for example, the preset intervals are 10 minutes, 20 minutes, or one hour, etc., and it is noted that the preset intervals may be set according to actual needs, which is not limited specifically herein.
Further, in an implementation manner of this embodiment, the determining location information of the terminal device specifically includes:
determining preset time according to the specific absorption rate test scene;
and determining the position information of the terminal equipment every interval of the preset time.
Specifically, the location information may be a region such as a french region, a american region, or the like; the terminal equipment has different specific absorption rates under different specific absorption rate test scenes, so that the interval of the positioning time of the terminal equipment is set according to the specific absorption rate test scenes. For example, when the level of the head SAR test scene SAR needs to be detected during the call, the preset time can be set to be 10 minutes; and when the communication is not performed, the level of the body SAR test scene SAR can be detected, and correspondingly, the preset time can be set to be 30 minutes. Of course, in practical application, the embodiment of the present invention further divides the positioning time interval according to factors such as whether the terminal is turned on or not, and specifically, the preset time can be further shortened on the basis of the foregoing, but the power consumption/operation speed of the terminal device needs to be comprehensively considered. In addition, in this embodiment, the terminal device may also perform auxiliary positioning by other positioning means, for example, positioning by using a base station, so as to further improve positioning accuracy.
S300, determining the working frequency band used by the current antenna of the terminal equipment.
In this embodiment, according to the mobile communication frequency band division standard, different operators and different network types use different network frequency bands, for example, the frequency band used by the GSM900 system of the mobile in china is uplink 890-909MHz and downlink 935-954MHz; the frequency band used by the GSM900 system of China Unicom is uplink 909-915MHz and downlink 954-960MHz; the frequency band used by the CDMA800 system of China telecom is uplink 825-835MHz and downlink 870-880MHz; for FDD-LTE system, the frequency band used by China Unicom is uplink 1755-1765MHz, downlink 1850-1860MHz, and the frequency band used by China telecom is uplink 1765-1780MHz, downlink 1860-1875MHz; for WLAN networks, the operating band is 2400-2483MHz.
Therefore, in this embodiment, the current operating frequency band of the terminal device may be determined according to the network access data in the terminal device. For example, when the terminal equipment is accessed to the WiFi network, the current working frequency band of the terminal equipment can be determined to be 2400-2483MHz; for another example, when the user uses the terminal device to make a call, if the SIM-card installed in the terminal device is a GSM card for china mobile, the current network access data of the terminal device is a 2G network for china mobile, so that it can be determined that the current working frequency band of the terminal device is uplink 890-909MHz and downlink 935-954MHz.
Further, a plurality of applications may be installed in the terminal device, and some applications may need network support when running, for example, live broadcast applications, shopping platforms, etc., while some applications may not need to rely on a network when running, such as a single click game application. Therefore, the applications installed in the terminal equipment can be divided into network applications and non-network applications, the applications which need to be supported by the network in the running process are the network applications, and the applications which do not need to be supported by the network in the running process are the non-network applications. As a possible implementation manner, in this embodiment, the current operating frequency band of the terminal device may be determined according to the type of the application currently running in the terminal device. As an example, if the application running in the terminal device is a voice call application, it may be determined that the application type of the application currently running in the terminal device is a non-network application, and it is determined that the current working frequency band of the terminal device is a voice call frequency band, and it may be further determined that a specific working frequency band is determined according to the type of the SIM card used by the terminal device; if the application currently operated by the terminal device is a shopping platform, the application type of the application currently operated by the terminal device is a network application, and at this time, the current working frequency band of the terminal device can be further determined according to the network currently opened by the terminal device, such as a WiFi, 3G, 4G or 5G network.
S400, adjusting the transmitting power of the antenna according to the specific absorption rate test scene, the position information, the working frequency band and the transmitting power of the antenna.
In this embodiment, the mapping relationship between the specific absorption rate test scene, the location information, the operating frequency band and the transmitting power is pre-stored in the terminal device, so that the transmitting power of the antenna is adjusted according to the specific absorption rate test scene, the location information, the operating frequency band and the transmitting power of the antenna. In practical application, after the terminal equipment finishes self positioning in the use process, according to the self-made regional position information and the specific absorption rate test scene, corresponding power parameters can be found according to the mapping relation, so that the PA (radio frequency power amplifier) works under the corresponding parameters, and the maximum power output by the PA is realized according to the parameters. Correspondingly, in this embodiment, the adjusting the transmitting power of the antenna according to the specific absorption rate test scenario, the location information, the operating frequency band, and the specific absorption rate test scenario is specifically: and adjusting the maximum value of the transmitting power of the antenna according to the specific absorption rate test scene, the position information, the working frequency band and the specific absorption rate test scene.
In practical applications, in this embodiment, the adjusting the maximum value of the transmitting power of the antenna according to the specific absorption rate test scenario, the location information, the operating frequency band, and the specific absorption rate test scenario specifically includes:
s401, determining a target power value corresponding to the working frequency band used by the antenna according to the position information and the specific absorption rate test scene;
s402, adjusting the maximum value of the transmitting power of the antenna in the working frequency band to be the corresponding target power value.
Specifically, since the relation coefficient of the antenna to the SAR is determined after the antenna design is determined, at this time, the factor affecting the SAR value, that is, the power output by the PA, is determined, the higher the PA output power, the stronger the radiation intensity radiated by the antenna is, and the higher the corresponding SAR value is, the specification requirement of the SAR guarantee local area is met by adjusting the output power of the PA in the embodiment.
For example, the setting of the power of the test scene in different regions and different specific absorption rates corresponding to a certain operating frequency band may be specifically as shown in table 1:
TABLE 1
As can be seen from table 1, one terminal typically supports a plurality of frequency bands, each of which is set as in the above table, but specific power values may be different, and power values reaching the same SAR control level may be different because antenna efficiency and radiation directivity are different for each frequency band.
In this embodiment, after updating the location of the terminal device, the query of the pre-stored location and the power parameter information may be performed again, and if the power parameter different from the last time needs to be used, the PA is controlled to operate according to the new power parameter. That is, when the terminal device uses the antenna to perform communication, the transmission power of the antenna when performing communication in the operating frequency band is controlled to be not more than the maximum value of the adjusted transmission power.
In the embodiment of the invention, after the antenna design is fixed, the SAR value is directly related to the power output by the PA, and the larger the power output by the PA is, the larger the SAR value is. However, too large SAR values are not allowed, but too low power output by the PA may affect normal wireless communication of the terminal device. Therefore, after the output power of the PA needs to be carefully debugged, the output power of the mobile terminal with a balance point fixed position is found according to specific conditions of SAR and radiation power. Different countries or regions have different requirements for SAR values and radiated power, so the output power of a mobile terminal may be different in different countries and regions.
Compared with the prior art, the embodiment of the invention sets the maximum power condition of work based on the region used by the terminal equipment, meets local laws and regulations, meets SAR limit value requirements, can maximally ensure radiation power, and avoids excessive power reduction so as not to influence communication quality and communication distance.
