Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and more particularly to a power control method, device and storage medium. Background Art

[0002] Terminals often need to perform data, phone calls and other services in a network environment, so they need to exchange information with nearby base stations. As we all know, terminals need to use a certain power to push data to nearby base stations, and in order to make the terminal's specific absorption rate (SAR) value meet the operator's certification requirements, the maximum transmission power of the terminal is usually limited.

[0003] In the related technologies, in order to meet the certification requirements of various operators and ensure that the SAR value does not exceed the standard, strict and uniform restrictions are imposed on the maximum transmission power of all combinations in a certain scenario. The related technical solutions can only meet the indicator requirements of operators in fixed scenarios, but cannot comprehensively consider the impact of multiple scenarios, the proportion of transmission time and other factors. Therefore, it is often impossible to increase the user's data throughput rate, transmission rate, and drop rate, and it is impossible to protect users from radiation in more scenarios. Therefore, the scenario for reducing the SAR value is relatively single, the power control is also relatively fixed and not smart enough, and the user experience is not good.

[0040] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0041] In related technologies, terminals often need to perform data, phone calls and other related services in a network environment, so the terminal needs to exchange information with nearby base stations. The terminal needs to have a certain power to push data to nearby base stations, and the mobile phone's specific absorption rate value needs to meet the operator's certification requirements. Therefore, the maximum transmission power of the terminal is usually limited.

[0042] In the related art, when the terminal transmits data with the base station, the terminal supports many combinations such as 2G / 3G / 4G / 5G / Carrier Aggregation (CA) / Long Term Evolution (LTE) and 5G Dual-Connectivity (ENDC) / NRCA. Each combination needs to measure the specific absorption rate value to determine how much power needs to be backed off to meet the operator's requirements in a specific scenario so that the specific absorption rate value does not exceed the standard. The maximum transmission power of all combinations of 2G / 3G / 4G / 5G / CA / ENDC / NRCA in a certain scenario is strictly and uniformly restricted. For example: when the N41 type frequency band of Time Division Duplexing (TDD) is transmitted in the body scenario, the transmission power needs to be backed off by 2dB, and when the N78 type frequency band is transmitted in the head mode, it needs to be backed off by 5.5dB. The restriction on the maximum transmission power of all combinations is relatively fixed and not intelligent enough, and the impact of the actual transmission time ratio on the power is not comprehensively considered, which in turn affects the user experience.

[0043] In the related art, the scene in which the terminal is currently located is identified based on the many sensors that come with the terminal. The related technical solution uses the SAR sensor to monitor the handset switch to distinguish between head or body modes. In an application scenario, for example: when a user answers a call, the handset is turned on, and based on the SAR sensor, the scene in which the terminal is currently located is identified as a head scene, and the transmit power backoff value of the head is called to appropriately reduce the transmit power to reduce the radiation hazard of the mobile phone to the human body. When the handset is turned off, based on the SAR sensor, the scene in which the terminal is currently located is identified as a body scene, that is, the transmit power backoff value of the body scene is called to appropriately increase the transmit power. However, in the body scene in the related technical solution, the user may use data services for a long time when the handset is turned off. Therefore, the scenarios of the reduced absorption rate values ​​identified by the related technical solution are relatively simple, with only two scenarios: head and body.

[0044] In the relevant technical solutions, in some scenarios, such as gaming scenarios, long-term gaming scenarios pose certain radiation hazards to users, and it is necessary to appropriately increase the transmit power backoff value to appropriately reduce the transmit power and improve the radiation situation for users in gaming scenarios. In other scenarios, such as sleeping scenarios, when no data services are performed, it is not necessary to reduce the transmit power backoff value too much to ensure communication performance. Compensation can be made based on the current SAR transmit power backoff value, and the transmit power backoff value can be reduced less and the transmit power can be appropriately increased.

[0045] In view of this, the present disclosure provides a power control method, which obtains the current power backoff value through the transmission time ratio, obtains the compensated power backoff value based on the current power backoff value and the power backoff value of the current SAR sensor, and intelligently controls the transmission power of the frequency band, thereby improving data services and enhancing user experience.

[0046] In the embodiments of the present disclosure, the specific implementation process of the power control method is further explained.

[0047] Figure 1 is a flow chart of a power control method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0048] In step S11, in response to the terminal transmitting a signal in a time division multiplexing manner in a current frequency band, a current transmission time proportion of the signal is determined.

[0049] In the disclosed embodiment, the current transmission time ratio represents the percentage of the current transmission time to the total time in a cycle. The transmission time ratio may also be the transmission reception time ratio, which represents the ratio of the transmission time to the reception time.

[0050] In step S12, in response to the current transmission time proportion being less than a threshold, the current SAR sensor power backoff value of the terminal is compensated based on the transmission time proportion to obtain a compensated SAR sensor power backoff value.

[0051] In the disclosed embodiment, the threshold value may be pre-set, for example, the pre-set threshold value is 35%, and the current transmission time accounts for 18%, which is less than the preset threshold value. Then, based on the transmission time accounting for 18%, the current SAR sensor power backoff value of the terminal may be compensated to obtain the compensated SAR sensor power backoff value.

[0052] In step S13, based on the compensated SAR sensor power back-off value, the signal transmission power of the terminal in the current frequency band is controlled.

[0053] In the disclosed embodiment, the signal transmission power of the terminal in the current frequency band is the maximum value of the signal transmission power, and the actual transmission power is less than or equal to the maximum value of the signal transmission power.

[0054] In the disclosed embodiment, different power back-off values ​​correspond to the current transmission time ratio, and the actual transmission time ratio is taken into consideration, so that the transmission power can be intelligently controlled, and data services can be more intelligently allocated to improve user experience.

[0055] In the embodiment of the present disclosure, the specific implementation process of the method for obtaining the power back-off value is further explained.

[0056] Figure 2 is a flow chart showing a method for obtaining a power backoff value according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0057] In step S21, the current transmission time proportion range to which the current transmission time proportion belongs is determined, and based on the correspondence between the transmission time proportion range and the power backoff compensation value, the current power backoff compensation value corresponding to the current transmission time proportion range is determined.

[0058] In the embodiment of the present disclosure, the correspondence between the transmission time proportion range and the power backoff compensation value is pre-set, and multiple transmission time proportion ranges can be divided. For example, the transmission time proportion ranges are pre-divided into a first transmission time proportion range, a second transmission time proportion range, and a third transmission time proportion range. The corresponding power backoff compensation values ​​are pre-set as a first power backoff compensation value, a second power backoff compensation value, and a third power backoff compensation value. The range to which the current transmission and reception event proportion belongs is the second transmission time proportion range. Based on the preset correspondence, the current power backoff compensation value corresponding to the current transmission time proportion range is obtained as the second power backoff compensation value.

[0059] In step S22, the difference between the current SAR sensor power backoff value and the current power backoff compensation value is used as the compensated SAR sensor power backoff value.

[0060] In the disclosed embodiment, if the current SAR sensor power backoff value is less than the current power backoff compensation value, the difference between the current SAR sensor power backoff value and the current power backoff compensation value is calculated, and the compensated SAR sensor power backoff value is negative, indicating that the current transmit power needs to be reduced. If the current SAR sensor power backoff value is equal to the current power backoff compensation value, the difference between the current SAR sensor power backoff value and the current power backoff compensation value is calculated, and the compensated SAR sensor power backoff value is zero, indicating that the current transmit power is maintained. If the current SAR sensor power backoff value is greater than the current power backoff compensation value, the difference between the current SAR sensor power backoff value and the current power backoff compensation value is calculated, and the compensated SAR sensor power backoff value is positive, indicating that the current transmit power needs to be increased.

[0061] In the disclosed embodiment, the current power backoff compensation value is obtained based on a preset corresponding relationship, and the difference between the current SAR sensor power backoff value and the current power backoff compensation value is calculated to obtain the compensated SAR sensor power backoff value. In combination with the transmission time proportion of the current frequency band, the power backoff value of the current SAR sensor is adjusted, which can improve data services and enhance user experience.

[0062] In the embodiment of the present disclosure, the corresponding relationship between the transmission time proportion range and the power backoff compensation value satisfies at least one of the following:

[0063] Multiple transmission time ratio ranges, and different transmission time ratio ranges correspond to different power back-off compensation values;

[0064] The first power backoff compensation value is less than the second power backoff compensation value, wherein the first transmission time proportion range corresponds to the first power backoff compensation value, the second transmission time proportion range corresponds to the second power backoff compensation value, and the maximum transmission time proportion within the first transmission time proportion range is greater than or equal to the minimum transmission time proportion within the second transmission time proportion range.

[0065] In the disclosed embodiment, a plurality of different transmission time proportion ranges corresponding to different power back-off compensation values ​​are pre-set, and the power back-off value of the current SAR sensor is adjusted in combination with the transmission time proportion of the current frequency band, which can improve data services and enhance user experience.

[0066] In the disclosed embodiment, the specific implementation process of the method for obtaining the intelligent control of the transmission power is further explained.

[0067] Figure 3 is a flow chart of a method for intelligently controlling transmission power according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0068] In step S31, the process of the intelligent transmission power control method starts.

[0069] In step S32, the current terminal registration information is monitored.

[0070] In the disclosed embodiment, the terminal registration information includes the frequency band type of the current terminal, and the upper layer UE obtains the frequency band type of the current terminal by monitoring the current terminal registration information.

[0071] In step S33, it is determined whether the frequency band type of the current terminal is a TDD frequency band.

[0072] In the disclosed embodiment, the TDD frequency band performs transmission and reception in time periods, that is, the proportion of transmission time changes dynamically within the range of 0 to 100%.

[0073] In the disclosed embodiment, the transmission power of all 4G / 5G TDD frequency bands can be intelligently controlled. For example, when the N41 transmission time accounts for 0%-15%, the transmission power can be appropriately increased by 3.5dB. When the N41 transmission time accounts for 15%-25%, the transmission power can be appropriately increased by 2dB. When the N41 transmission time accounts for 25%-35%, the transmission power can be appropriately increased by 0.5dB. When the N41 transmission time accounts for ≥35%, the transmission power is obtained according to the fixed value power backoff value. Among them, the B34, B38, B39, B40, B41, B42, N77, N78 and other types of frequency bands in the 4G or 5G TDD frequency bands can intelligently control the backoff value according to the transmission / reception time ratio. The power improvement of intelligently controlling the transmit power based on the transmit time ratio of different TDD frequency bands (the second solution in Table 1 below) and controlling the transmit power using a fixed power backoff value without distinguishing the transmit time ratio (the first solution in Table 1 below) under different transmit time ratios is shown in the following table:

[0074] N41(SAR back-off 6dB) 15％ 25％ 35％ 45％ 55％ 66％ Expected power (dB) 23.5 22 20.5 20 20 20 First solution power (dB) 20 20.1 20.1 20.1 20 20 Second solution power (dB) 23.7 22.1 20.6 20.1 20 20 Power boost(dB) 3.7 2 0.5 0 0 0

[0075] Table 1 Power increase under different transmission time ratios

[0076] In the disclosed embodiment, it can be seen from Table 1 that the fixed power fallback value of the TDD band for the N41 type is 6dB. In the N41 band, when the transmission time accounts for 15%, the expected power of the current band is 23.5dB, the power obtained by the first scheme is 20dB, and the power obtained by the second scheme is 23.7dB. The power of the second scheme is increased by 3.7dB compared with the first scheme, and the power obtained by the second scheme reaches the expected power of the current band. When the transmission time accounts for 25%, the power of the second scheme is increased by 2dB compared with the first scheme. When the transmission time accounts for 35%, the power of the second scheme is increased by 0.5dB compared with the first scheme. Based on the power obtained by the second scheme, the power can be increased and the expected power of the current band in the current transmission time ratio range can be achieved. When the transmission time accounts for greater than or equal to 35%, both the second scheme and the first scheme control the transmission power through a fixed value, so in this case, the power is not increased compared with the two schemes.

[0077] In the disclosed embodiment, the fallback value of each frequency band in a certain scenario of the first solution is fixed. For example, in the body scenario, the fixed power fallback value of N41 is 6dB, so the original transmission power of 26dB is subtracted by 6dB, so the actual maximum transmission power can only reach 20dB. However, the transmission time proportion of the TDD frequency band changes dynamically within the range of 0 to 100%. The first solution does not take into account the transmission time proportion. In fact, power fallback is performed based on the transmission time proportion of 100%. Although such a fallback solution can meet the operator certification requirements, it also reduces part of the transmission power, affects the use of data services, and affects the user experience.

[0078] In step S34, if the judgment result is no, that is, the frequency band type of the current terminal is not the TDD frequency band, the original transmission power is maintained.

[0079] In the disclosed embodiment, if the current frequency band type is not a TDD frequency band, there is no need to adjust the transmit power, and the original transmit power is maintained.

[0080] In step S35, if the judgment result is that the frequency band type of the current terminal is the TDD frequency band, the transmission time ratio is monitored.

[0081] In the disclosed embodiment, if the current frequency band type is a TDD frequency band, it is necessary to further monitor the transmission time ratio to determine whether the transmission power needs to be increased.

[0082] In step S36, it is determined that the current frequency band type is a TDD frequency band, and it is determined whether the transmission time ratio is less than 15%.

[0083] In step S37, if the judgment result is yes, that is, the transmission time accounts for less than 15%, the first transmission power is obtained based on the first SAR reduction parameter.

[0084] In the disclosed embodiment, the current frequency band type is a TDD frequency band, and the transmission time accounts for less than 15%, then the current SAR reduction parameter is the first SAR reduction parameter corresponding to the transmission time proportion range of 0%-15%, and the compensated first SAR sensor power backoff value is obtained based on the difference between the original SAR reduction parameter and the first SAR reduction parameter, and the compensated current first transmission power is obtained based on the original transmission power and the compensated first SAR sensor power backoff value.

[0085] In step S38, if the judgment result is no, that is, the transmission time proportion is not less than 15%, it is further judged whether the transmission time proportion is less than 25%.

[0086] In the disclosed embodiment, if it is determined that the transmission time proportion is not less than 15%, it indicates that the transmission time is not within the first time range of 0%-15%, and then it is further determined whether the transmission time proportion is less than 25%.

[0087] In step S39, if the judgment result is yes, that is, the transmission time accounts for less than 25%, the second transmission power is obtained based on the second SAR reduction parameter.

[0088] In the embodiment of the present disclosure, if it is determined that the transmission time ratio is not less than 15%, and it is further determined that the transmission time ratio is less than 25%, the current SAR reduction parameter is the second SAR reduction parameter corresponding to the transmission time ratio range of 15%-25%. Based on the difference between the power backoff value of the current SAR sensor and the second SAR reduction parameter, the compensated second SAR sensor power backoff value is obtained, and based on the original transmission power and the compensated second SAR sensor power backoff value, the compensated current second transmission power is obtained.

[0089] In step S310, if the result of the determination is no, that is, the transmission time proportion is not less than 25%, it is further determined whether the transmission time proportion is less than 35%.

[0090] In the disclosed embodiment, if it is determined that the transmission time proportion is not less than 25%, it indicates that the transmission time is not within the first time range of 15%-25%, and then it is further determined whether the transmission time proportion is less than 35%.

[0091] In step S311, if the judgment result is yes, that is, the transmission time accounts for less than 35%, then the third transmission power is obtained based on the third SAR reduction parameter.

[0092] In the embodiment of the present disclosure, if it is determined that the transmission time ratio is not less than 25%, and it is further determined that the transmission time ratio is less than 35%, the current SAR reduction parameter is the third SAR reduction parameter corresponding to the transmission time ratio range of 25%-35%. Based on the difference between the power backoff value of the current SAR sensor and the third SAR reduction parameter, the compensated power backoff value of the third SAR sensor is obtained, and based on the original transmission power and the compensated power backoff value of the third SAR sensor, the compensated current third transmission power is obtained.

[0093] In step S312, if the judgment result is no, that is, the transmission time accounts for no less than 35%, the original transmission power is maintained.

[0094] In the disclosed embodiment, if it is determined that the transmission time accounts for no less than 35%, there is no need to adjust the transmission power, and the original transmission power is maintained.

[0095] In the embodiment of the present disclosure, a specific implementation process of a method for determining a current SAR sensor power back-off value is described.

[0096] Figure 4 is a flow chart showing a method for determining a current SAR sensor power back-off value according to an exemplary embodiment. Figure 4As shown, the following steps are included:

[0097] In step S41, the current usage scenario of the terminal is identified as a target usage scenario based on the non-SAR sensor, and the target usage scenario is a scenario for performing SAR sensor power backoff.

[0098] In the disclosed embodiment, the scenario for performing power fallback of the SAR sensor may be pre-set, and may be some commonly used scenarios requiring power fallback, such as head scenario, body scenario, game scenario, sleep scenario, etc.

[0099] In step S42, the target SAR sensor power backoff value corresponding to the target usage scenario is used as the current SAR sensor power backoff value.

[0100] In the disclosed embodiment, different target usage scenarios are preset to correspond to different target SAR sensor power backoff values. For example, the target SAR sensor power backoff value corresponding to the sleeping scene is preset to be 5dB, and the current SAR sensor power backoff value is 5dB.

[0101] In the disclosed embodiment, the current SAR sensor power backoff value is determined based on the identified target scene, and the current scene is taken into consideration to improve the service data usage and enhance the user experience.

[0102] In an embodiment of the present disclosure, identifying the current usage scenario of the terminal as a target usage scenario based on a non-SAR sensor includes: in response to monitoring that the foreground application currently running on the terminal is a preset whitelist application, determining that the current usage scenario of the terminal is identified as the target usage scenario.

[0103] In the disclosed embodiment, some commonly used application information is stored in the whitelist application, which may be: a game application.

[0104] In the disclosed embodiment, by matching the current application information with the application information in the preset whitelist to identify whether the current scene is the target usage scene, the scenes for controlling power can be increased and the user experience can be improved.

[0105] In the disclosed embodiment, the current scene of the terminal can be identified through various sensors in the terminal.

[0106] Figure 5 is a schematic diagram showing a method for identifying a current scene according to an exemplary embodiment. Figure 5 As shown, including:

[0107] The terminal's internal sensor identifies the current scene based on the monitored scene information, and sends the current scene information to the modem through the application processor or sensor core. The modem calls the fallback power corresponding to the current scene to control the current transmit power.

[0108] In the disclosed embodiment, while retaining the head and body scenes, new game and sleep scenes are added. In the game scene, long-term gaming will inevitably cause certain radiation hazards to the human body. In the sleep scene, the irregular network searches of mobile phones at night also need to interact with base stations, which will also cause certain hazards to the human body. Therefore, it is meaningful to add recognition of game scenes and sleep scenes.

[0109] In the embodiments of the present disclosure, a specific implementation process of a method for determining a power backoff value based on a target scenario is described.

[0110] Figure 6 is a flow chart showing a method for determining a power backoff value based on a target scenario according to an exemplary embodiment. Figure 6 As shown, including:

[0111] Different display serial interface specifications (DSI) values ​​corresponding to different scenes are preset, and different DSI values ​​correspond to different fallback powers. Set the head scene to correspond to DSI=1, corresponding to fallback power 1. Set the body scene to correspond to DSI=2, corresponding to fallback power 2. Set the game scene to correspond to DSI=3, corresponding to fallback power 3. Set the sleep scene to correspond to DSI=4, corresponding to fallback power 4.

[0112] Start scene detection, identify the current scene as a head scene, body scene, game scene or sleep scene, the wireless access point (Access Point, AP) sends the command prompt corresponding to the current scene, and sends the DSI value corresponding to the scene to the modem through the Qualcomm Messaging Interface (Qualcomm Messaging Interface, QMI) based on the communication protocol. If the current scene is identified as a head scene, the fallback power 1 corresponding to the head scene is called. If the current scene is identified as a body scene, the fallback power 2 corresponding to the body scene is called. If the current scene is identified as a game scene, the fallback power 3 corresponding to the game scene is called. If the current scene is identified as a sleep scene, the fallback power 4 corresponding to the sleep scene is called.

[0113] In the disclosed embodiment, for example: when the current scene is identified as a game scene, the AP sends a command prompt corresponding to the current game scene, and based on the communication protocol, sends the DSI value corresponding to the game scene (i.e., DSI=3) to the modem through the Qualcomm communication interface QMI, and calls the fallback power 3 corresponding to the game scene.

[0114] In the embodiment of the present disclosure, different target scenarios are preset to correspond to different power fallback values, and more power control scenarios are added, which can improve user experience.

[0115] In the disclosed embodiment, the specific implementation process of the method for determining the game scene is described.

[0116] Figure 7 is a flowchart of a method for determining a game scene according to an exemplary embodiment. Figure 7 As shown, the following steps are included:

[0117] In step S61, the current scene starts to be recognized.

[0118] In step S62, the usage of the foreground application is monitored.

[0119] In the embodiment of the present disclosure, the upper-layer AP may monitor the usage of the foreground application. The upper-layer AP may execute operations such as the operating system, user interface, and application program. The structure of the AP may include: a central processing unit, a graphics processing unit, and a neural network engine, etc.

[0120] In step S63, it is determined whether the current foreground application is a whitelist application.

[0121] In the disclosed embodiment, some commonly used game application information is pre-stored in the whitelist, and when the user opens these game applications, the upper layer AP will send the underlying current application information through the interface.

[0122] In step S64, if the current foreground application is a whitelist application, the radio interface layer (Radio Interface Layer, Ril) sends down the DSI.

[0123] In the disclosed embodiment, if the current application successfully matches the application in the whitelist, the wireless access point of the upper layer AP will send the DSI value to the bottom layer through the wireless interface layer Ril.

[0124] In step S65, if the current foreground application is not a whitelist application, other SAR reduction parameters are called.

[0125] In the disclosed embodiment, if the foreground application used fails to match the application included in the whitelist, indicating that the foreground application currently used is not a commonly used gaming application and the current target scene is not a gaming scene, the SAR reduction parameter corresponding to the current DSI value is called based on the current DSI value.

[0126] In step S66, it is determined whether the value of the DSI sent by the radio interface layer Ril is 3.

[0127] In the disclosed embodiment, based on matching the current application with the applications in the whitelist, it is determined that the current scene is a game scene, and it is necessary to further confirm whether the current target scene is a game scene based on the DSI value.

[0128] In the disclosed embodiment, if the value of DSI is not 3, the process returns to step S65 and calls other SAR reduction parameters.

[0129] In the disclosed embodiment, if the current application successfully matches the whitelist application, but the DSI value is different from the DSI value corresponding to the preset game scene, it is confirmed that the current target scene is not the game scene, and the corresponding SAR reduction parameter is called based on the current DSI value.

[0130] In step S67, if the value of DSI is 3, the game scene SAR reduction parameter is called.

[0131] In the disclosed embodiment, if the current application matches the whitelist application successfully, and the DSI value is the DSI value corresponding to the preset game scene, that is, DSI=3, then the current target scene is confirmed to be the game scene and the SAR reduction parameter corresponding to the game scene is called, that is, the fallback power 3 is called.

[0132] In an embodiment of the present disclosure, identifying the current usage scenario of the terminal as a target usage scenario based on a non-SAR sensor includes: in response to detecting that the terminal is not currently performing a data service and the current time is night time, determining that the current usage scenario of the terminal is identified as the target usage scenario.

[0133] In the embodiment of the present disclosure, in response to detecting that the terminal is not currently performing data services, indicating that the current user may not be using the terminal, and determining that the current time is night time, combining the two conditions can determine that the current usage scenario can be a target sleep usage scenario.

[0134] In the disclosed embodiment, the current target usage scenario is determined to be nighttime based on data service information and the current time. Compared with scene recognition using a SAR sensor, more control power scenarios are added, data service usage is improved, and user experience is enhanced.

[0135] In the disclosed embodiment, a specific implementation process of the method for determining a sleep scene is described.

[0136] Figure 8 is a flowchart of a method for determining a sleep scene according to an exemplary embodiment. Figure 8 As shown, the following steps are included:

[0137] In step S71, the current scene starts to be recognized.

[0138] In step S72, the usage time and the usage of the foreground application are monitored.

[0139] In the embodiment of the present disclosure, the upper layer AP may monitor the usage time to determine whether the current usage time is night time, and the foreground application usage may include data service status.

[0140] In step S73, it is determined whether there is no data service.

[0141] In step S74, if no data service is detected, the terminal usage time is detected.

[0142] In the disclosed embodiment, if no data service is detected, the usage time is further detected to confirm whether the current scene is a sleep scene.

[0143] In step S75, if data services are detected, other SAR reduction parameters are called.

[0144] In the disclosed embodiment, if data services are detected, it is determined that the current target scene is not a sleep scene, and corresponding SAR reduction parameters are called based on the current DSI value.

[0145] In step S76, if no data service is detected, the usage time is continuously monitored to determine whether it is at night.

[0146] In the disclosed embodiment, if data services are detected, the usage time is continuously monitored, and it is further determined whether it is at night to further determine whether the current target scene is a sleeping scene.

[0147] In the disclosed embodiment, if it is determined that it is not at night, the process returns to step S75 and other SAR reduction parameters are called. If data services are detected but it is not at night, it is determined that the current target scene is not a sleeping scene, and the corresponding SAR reduction parameters are called based on the current DSI value.

[0148] In step S77, if it is determined to be at night, the sleeping scene SAR reduction parameters are called.

[0149] In the disclosed embodiment, if data services are monitored and it is currently nighttime, the current target scene is determined to be a sleeping scene, the sleeping scene SAR reduction parameters are called, and the DSI is sent down through the radio interface layer Ril.

[0150] In step S78, if data service is detected and it is nighttime, it is determined whether the value of DSI is 4.

[0151] In the disclosed embodiment, if data services are detected and it is currently nighttime, it is necessary to further determine whether the DSI value sent by the radio interface layer Ril is 4, and then further determine that the current target scene is a sleeping scene.

[0152] In the disclosed embodiment, if the value of DSI is not 4, then return to step S75 and call other SAR reduction parameters. If business data is detected and it is currently at night, but the value of DSI is not 4, it is determined that the current target scene is not a sleeping scene, and then the corresponding SAR reduction parameter is called based on the current DSI value.

[0153] In step S79, if the value of DSI is 4, the sleep scene SAR reduction parameter is called.

[0154] In the disclosed embodiment, if business data is monitored, it is currently at night, and the DSI value is 4, it is determined that the current target scene is a sleep scene, and the sleep scene SAR reduction parameter is called, that is, the fallback power 4 is called.

[0155] In the disclosed embodiment, for example: if the user has not used the application for data services for more than 30 minutes and recognizes that the current time is from 10 pm to 7 am the next day, the current target scene is determined to be a sleep scene, and the upper-layer application processor will send DSI=4 to the bottom layer and call the SAR parameters of the sleep scene.

[0156] In the embodiment of the present disclosure, whether the current scene is a sleep scene is identified based on application usage, usage time, service data status, and whether it is night time conditions, and the sleep scenes commonly used by users are added to the control transmission power scene, which can improve service usage and enhance user experience.
