Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, a specific absorption rate adjustment method is provided, and this embodiment is illustrated by applying the method to a terminal, and it is to be understood that the method may also be applied to a server, and may also be applied to a system including the terminal and the server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes steps S110 to S140.
Step S110, acquiring a current first specific absorption rate adjustment mode of the mobile terminal.
Wherein Specific Absorption Rate (SAR) refers to the amount of electromagnetic radiation energy absorbed per unit mass of material per unit time. The specific absorption rate adjustment mode indicates that, in the scenario, if the specific absorption rate adjustment is triggered, the mobile terminal is controlled to operate in a manner corresponding to the specific absorption rate adjustment mode. It is common that when certain specific scenarios are triggered, the specific absorption rate needs to be limited, and therefore, the transmission power of the mobile terminal needs to be controlled to ensure that the specific absorption rate meets the corresponding regulatory limit. In one embodiment, the specific absorption rate adjustment mode includes: a specific absorption rate adjustment mode based on static control and a specific absorption rate adjustment mode based on time-averaged power control. In other embodiments, the specific absorption rate adjustment mode may be controlled in other ways.
In this embodiment, the specific absorption rate adjustment mode in which the mobile terminal is currently located is obtained and recorded as a first specific absorption rate adjustment mode. It should be noted that the terms "first", "second", and the like in the present application are used only for distinguishing the names, and do not mean any actual meanings.
And step S120, detecting the current application scene of the mobile terminal.
In one embodiment, the application scene in which the mobile terminal is located refers to the current usage scene of the mobile terminal itself. For example, the mobile terminal is currently in a reading mode, in a game mode, in a live watching mode, in a video call, and other application scenarios; for example, the application scene of the mobile terminal is divided to a certain extent, for example, the current application scene of the mobile terminal belongs to a continuous uploading mode, or the application scene belongs to a discontinuous transmission mode, and the like. In other embodiments, the application scenario of the mobile terminal may be divided in other manners.
Further, in an embodiment, as shown in fig. 2, detecting an application scenario in which the mobile terminal is currently located includes steps S121 to S123.
Step S121, the communication performance index of the mobile terminal is obtained.
The communication performance index of the mobile terminal may be used to represent the communication performance of the mobile terminal. In one embodiment, the communication performance index of the mobile terminal is obtained and includes uplink BLER, error rate, system response time, and the like; wherein, the BLER (block error rate) represents the ratio of the number of incorrectly received blocks to the total number of transmitted blocks, and the larger the BLER value, the higher the error rate. The error rate (SER) is an index for measuring the accuracy of data transmission within a predetermined time, and is the error rate of 100% of the total number of transmitted codes/bit error in transmission. The longer the system response time, the worse the communication performance. In other embodiments, the communication performance metrics of the mobile terminal may also include other metrics.
And step S122, monitoring an application program starting event of the mobile terminal.
When the application program is started, the corresponding application program starting event can be monitored. In this embodiment, whether the mobile terminal currently starts the application program may be detected by monitoring the application program start event.
Step S123, determining the current application scenario based on the communication performance index or the application program start event.
In an aspect of this embodiment, an application scenario of the mobile terminal is determined by using the communication state of the mobile terminal, and then an adjustment mode of the specific absorption rate is determined. On the other hand, different applications have their own functions, and the transmission power requirements corresponding to the applications with the same function are generally the same, so in this embodiment, the application scenario of the mobile terminal can be determined by detecting the application currently started by the mobile terminal, and then the required specific absorption rate adjustment mode is determined.
Further, in one embodiment, determining the current application scenario based on the communication performance indicator or the application start event includes: if a starting event of a specific application program is monitored, judging that the application scene of the mobile terminal is in a discontinuous transmission mode; and if the communication performance index of the mobile terminal determines that the preset condition is met currently, judging that the application scene where the mobile terminal is located is in a continuous uploading mode.
Wherein, the specific application program can be set by self according to the actual situation; in one particular embodiment, for example, the particular application includes a game, a web browser, and so forth.
The preset condition corresponding to the communication performance index can be set according to the actual situation. In one embodiment, the communication performance index satisfying the preset condition includes: the uplink BLER value exceeds a preset BLER threshold value in a preset time period; or the error rate exceeds a preset error rate threshold value; or the system response time exceeds a preset time, and the like. The preset time period and the preset BLER threshold value can be set to different values according to different network coverage areas; in one embodiment, the predetermined time period and the set value of the preset BLER threshold may be obtained from a test.
The persistent upload mode indicates that the mobile terminal continuously uploads data. In one embodiment, the application program belonging to the persistent upload mode comprises: live, send files, etc. scenes. The discontinuous transmission mode represents a characteristic that the mobile terminal does not send information when no data to be sent exists currently, such as during a no-call period. The specific absorption rate adjustment mode correspondingly set for the discontinuous transmission mode and the continuous upload mode will be described in detail in the subsequent embodiments.
Step S130, determining a corresponding second specific absorption rate adjustment mode according to the application scenario.
After detecting the application scenario of the mobile terminal, the specific absorption rate adjustment mode that should be used currently, that is, the second specific absorption rate adjustment mode in this embodiment, in one embodiment, the specific absorption rate corresponding to different application scenarios may be preset according to an actual situation, for example, a mapping relationship between each application scenario and the specific absorption rate adjustment mode is stored as a mapping relationship table, and after detecting the application scenario of the mobile terminal, the specific absorption rate adjustment mode corresponding to the current application scenario is searched from the mapping relationship table, so as to determine the second specific absorption rate adjustment mode.
In step S140, if the first specific absorption rate adjustment mode is different from the second specific absorption rate adjustment mode, the specific absorption rate adjustment mode of the mobile terminal is switched to the second specific absorption rate adjustment mode.
The first specific absorption rate adjustment mode is a specific absorption rate adjustment mode in which the mobile terminal is currently located, the second specific absorption rate adjustment mode is a specific absorption rate adjustment mode corresponding to a current application scenario, and if the first specific absorption rate adjustment mode and the second specific absorption rate adjustment mode are different, the mobile terminal should be controlled to switch the mode to the second specific absorption rate adjustment mode.
Further, in one embodiment, the switching may be directly performed if the first specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on static control and the second specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on time-averaged power control.
In another embodiment, if the first specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on time-averaged power control and the second specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on static control, the mobile terminal may be controlled to perform mode switching when it is determined that the switching condition is satisfied according to the transmission power control condition of the mobile terminal. Further, when controlling based on the time averaging algorithm, the mobile terminal keeps the average power of the transmit power at a fixed value for a period of time, so that the mode switching can be entered after ending a time averaging window.
In the present embodiment, before switching the specific absorption rate adjustment mode of the mobile terminal to the second specific absorption rate adjustment mode as shown in fig. 3, the method further includes step S310 and step S320.
In step S310, if the first specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on time-averaged power control and the second specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on static control, it is detected whether the current mobile terminal triggers a specific absorption rate adjustment scenario.
Step S320, if the current mobile terminal triggers the specific absorption rate adjustment scenario, when the operation of the current time averaging window is finished, the step of switching the specific absorption rate adjustment mode of the mobile terminal to the second specific absorption rate adjustment mode is performed.
If a specific absorption rate adjusting scene is triggered currently, and the adjusting scene is controlled based on the time averaging algorithm currently, the mode switching can be performed only after a time window of the time averaging algorithm is finished, so that the transmitting power of the mobile terminal in the mode switching process can always meet the regulatory requirement, and the corresponding specific absorption rate also meets the corresponding regulatory standard.
In another embodiment, if the current mobile terminal does not trigger the specific absorption rate adjustment scenario, the step of switching the specific absorption rate adjustment mode of the mobile terminal to the second specific absorption rate adjustment mode is directly entered.
In this embodiment, a switching rule is set for mode switching, that is, if the mode is switched from the mode based on the time-averaged power control to the mode based on the static control, when a scene of reducing the specific absorption rate is triggered, it is ensured that the switching is performed after a time window is finished, and it is ensured that the specific absorption rate of the mobile terminal is always kept within a corresponding standard range.
In one embodiment, a current first specific absorption rate adjustment mode of the mobile terminal is obtained every preset time, and an application scene where the mobile terminal is currently located is detected. When detecting that the current first specific absorption rate adjustment mode is different from the second specific absorption rate adjustment mode corresponding to the application scene, entering a step of switching the specific absorption rate adjustment modes, so that the mobile terminal adopts different specific absorption rate adjustment modes in different scenes, and the requirements of more scenes can be met.
In one embodiment, the default specific absorption rate adjustment mode is a specific absorption rate adjustment mode based on time-averaged power control when the mobile terminal is in an on state.
The specific absorption rate adjusting method comprises the steps of obtaining a current first specific absorption rate adjusting mode of the mobile terminal, obtaining an application scene where the mobile terminal is located, determining a corresponding second specific absorption rate adjusting mode according to the application scene, and switching the specific absorption rate adjusting mode of the terminal into the second specific absorption rate adjusting mode if the current mode is different from the second specific absorption rate adjusting mode, so that the mobile terminal carries out power according to the second specific absorption rate adjusting mode. The method switches the corresponding specific absorption rate adjustment mode according to the application scene where the mobile terminal is located, so that the specific absorption rate adjustment mode adopted by the mobile terminal at present can adapt to various different application scenes.
In one embodiment, as shown in fig. 4, the method further includes step S410: and acquiring the communication performance index of the mobile terminal.
The communication performance index of the mobile terminal may be used to represent the communication performance of the mobile terminal. In one embodiment, the communication performance index of the mobile terminal is obtained by uplink BLER, error rate, system response time and the like.
In this embodiment, after switching the current specific absorption rate adjustment mode of the mobile terminal to the second specific absorption rate adjustment mode, the method further includes step S420: and if the protection mechanism is determined to be triggered based on the communication performance index before switching and the communication performance index after switching, switching the specific absorption rate adjusting mode of the mobile terminal into a first specific absorption rate adjusting mode.
In this embodiment, the communication performance indicator before the handover indicates the communication indicator when the mobile terminal is in the first specific absorption rate adjustment mode, and the communication performance indicator after the handover indicates the communication indicator when the mobile terminal is in the second specific absorption rate adjustment mode. Detecting the communication performance of the mobile terminal according to the communication performance indexes before and after switching, and further judging whether the mode switching is reasonable or not; in one embodiment, if it is determined that the communication performance after the handover is worse than the communication performance before the handover based on the communication performance index, it is determined that the protection mechanism is triggered. Further, taking the example that the communication performance index includes the uplink BLER, when the average uplink BLER after switching is greater than the uplink BLER before switching, and the ratio of the difference to the ratio before switching is greater than a preset ratio, it is determined that the protection mechanism is triggered. In other embodiments, the protection mechanism may be triggered in other forms as well.
In this embodiment, a protection mechanism is set in the specific absorption rate adjustment mode switching of the mobile terminal. When the protection mechanism is triggered, it is indicated that the mode switching is unreasonable, and the switched specific absorption rate adjustment mode makes the communication performance of the mobile terminal worse than that before the switching, so that the mode switching needs to be cancelled, and the specific absorption rate adjustment mode of the mobile terminal is switched back to the first specific absorption rate adjustment mode.
In one embodiment, determining the corresponding second specific absorption rate adjustment mode according to the application scenario comprises: if the application scene is a continuous uploading mode, determining that the second specific absorption rate adjusting mode is a specific absorption rate adjusting mode based on static control; and if the application scene is a discontinuous transmission mode, determining the second specific absorption rate adjustment mode as the specific absorption rate adjustment mode based on time average power control.
The persistent upload mode indicates that the mobile terminal continuously uploads data. In one embodiment, the application program belonging to the persistent upload mode comprises: live, send files, etc. scenes. The discontinuous transmission mode represents a characteristic that the mobile terminal does not send information when no data to be sent exists currently, such as during a no-call period.
Further, in one embodiment, the specific absorption rate adjustment mode based on the static control includes: the transmit power of the mobile terminal is adjusted according to a static power reduction algorithm to reduce the specific absorption rate of the mobile terminal. Wherein, the algorithm for static power reduction comprises: the ability of the mobile terminal to transmit power is limited to a fixed value when triggering a reduced specific absorption rate scenario. The values of the limitation of different scenes and frequency bands may be different, but the limiting power values are always the same at different times at the same antenna position of the same frequency band in the same scene. So that the mobile terminal can always meet the corresponding regulatory standard. Fig. 5 is a diagram illustrating the transmission power corresponding to the specific absorption rate adjustment mode based on static control in one embodiment.
In one embodiment, the specific absorption rate adjustment mode based on time-averaged power control includes: the transmit power of the mobile terminal is adjusted according to a time-averaged power algorithm to reduce the specific absorption rate of the mobile terminal. The time-average power algorithm comprises the following steps: the average power of the transmit power of the mobile terminal over a period of time is maintained at a fixed value when triggering a reduced specific absorption rate scenario. In the same scene, the same frequency band and the same antenna position are at different time, the transmitting power of the mobile phone is not always the same, the mobile terminal is adjusted to the expected power or even the maximum power according to the control requirements of the base station and the like, but in order to keep the average power unchanged, the mobile terminal can reduce the transmitting power of the mobile terminal to be below the average power after a period of time, so as to ensure that the average power in a period of time meets the regulation requirement. Fig. 6 is a schematic diagram of the transmission power corresponding to the specific absorption rate adjustment mode based on the time-averaged power control in an embodiment.
The scene for triggering the reduction of the specific absorption rate can be set according to the actual situation, and different mobile terminals can be set to different triggering scenes. For example, in one embodiment, the distance between the mobile terminal and the human body is acquired through a sensor in the mobile terminal, and when the distance is smaller than a preset distance, it is determined that the specific absorption rate scene is triggered. In another embodiment, the specific absorption rate scenario is determined to be triggered when a network connection event of the mobile terminal is monitored. In other embodiments, the trigger to reduce specific absorption rate scenario may also be set to other scenarios.
In this embodiment, the specific absorption rate adjustment mode corresponding to the application scenario of the continuous uploading mode is set as the specific absorption rate adjustment mode based on static control, so that when a scenario of reducing the specific absorption rate is triggered, the specific absorption rate of the mobile terminal meets the corresponding regulatory standard, and the stability of uploading data of the mobile terminal is ensured. Setting a specific absorption rate adjustment mode corresponding to a discontinuous transmission mode of a scene such as a game, a web browsing and the like as a specific absorption rate adjustment mode based on time-averaged power control; when a scene of reducing the specific absorption rate is triggered, the specific absorption rate of the mobile terminal meets the corresponding regulatory standard, the mobile terminal keeps the maximum transmitting power capability, a guarantee is provided for transmitting key data in a short time under a weak field, and the mobile phone delay is reduced.
In one embodiment, the specific absorption rate adjustment method includes the following steps:
when the mobile terminal is detected to be turned on, setting the specific absorption rate adjustment mode of the mobile terminal as a default specific absorption rate adjustment mode, which is a specific absorption rate adjustment mode based on time average power control.
Monitoring an application program starting event of the mobile terminal, acquiring a communication performance index of the mobile terminal, (taking BLER as an example in the upper line), and determining the current application scene according to the monitored application program starting time or the communication performance index.
The application scenarios are divided into two types: discontinuous transmission mode and continuous uploading. The identification process of the application scenario is specifically shown in fig. 7, and includes:
(1) take the game mode belonging to the discontinuous transmission mode as an example:
when the modem side listens for a start event of a mainstream online gaming application, the specific absorption rate adjustment mode is switched to a specific absorption rate adjustment mode based on time-averaged power control.
(2) Other modes pertaining to continuous upload:
when the mobile terminal is in a non-game mode, the uplink BLER of the index communication index is obtained to judge the retransmission condition of the uplink data. Generally, the larger the BLER value, the more number of retransmission requests for uplink transmission. When it is detected that the BLER value is continuously higher on average for a period of time and higher than a certain value, indicating that the mobile terminal is currently in the continuous uploading mode and the communication condition is bad, the specific absorption rate adjustment mode is switched to the static control-based mode.
Further, in the process of switching the specific absorption rate adjustment mode, the following switching rule needs to be satisfied:
(1) the default state of the mobile terminal is set to be a mode based on time average power control;
(2) when switching from the mode based on time-averaged power control (dynamic algorithm mode) to the mode based on static control:
if the SAR reduction scene is not triggered currently, the switching can be directly carried out;
and if the SAR reduction scene is triggered currently, the time average window needing the equal time average power algorithm is operated to be ended, and then switching is carried out. And the radiation power of the mobile terminal is ensured to always meet the regulatory requirements in the switching process of the mobile terminal.
(3) When switching from the mode based on static control to the mode based on time-averaged power control, the switching can be done directly without latency.
Furthermore, a protection mechanism is set in the mode switching process of the mobile terminal, and the flow is shown in fig. 8:
the protection mechanism takes effect after each switching, the protection mechanism continuously counts the average value of uplink BLER of the communication performance index, if the average value of uplink BLER is more than A% before the switching within a period of time T after the switching, the protection mechanism takes effect, the specific absorption rate adjustment mode is switched to the last state again, and the switching rule always complies with the switching rule.
In one embodiment, auxiliary recognition of some sensors can be added, so that the accuracy of scene recognition can be effectively improved, and the accuracy of the specific absorption rate adjustment mode switching can be further improved.
