Specific Absorption Rate (SAR), as a key indicator for measuring the absorption of radio frequency energy by the human body, is subject to strict limitations.

[0003] Currently, specific absorption rate control methods typically employ a simple adjustment mechanism based on static power limits, which can lead to SAR exceeding the limit. Summary of the Invention

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0029] It should be understood that although the terms first, second, third, etc., may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0030] Currently, when a human body is detected approaching, the terminal typically reduces its transmission power using a fixed power backoff method to ensure that the SAR value meets safety standards. However, this static control method cannot adapt to the SAR requirements of different scenarios, lacks dynamic adjustment capabilities, and is prone to SAR exceeding the limit.

[0031] To address the aforementioned problems, this application proposes a specific absorption rate control method. The following embodiments are provided to further illustrate this application:

[0032] Please see Figure 1 , Figure 1This is a flowchart illustrating a specific absorption rate control method according to an exemplary embodiment of this application. The method can be applied to terminals with communication functions, such as smartphones, tablets, dedicated Bluetooth devices, digital broadcasting terminals, messaging devices, and personal digital assistants. The method can also be executed by other devices in different application scenarios, and this application embodiment does not limit this.

[0033] like Figure 1 As shown, the specific absorption rate control method may include the following steps:

[0034] Step 101: Obtain the status of the terminal's modem and / or the scene in which the terminal is located. The scene in which the terminal is located includes multiple scenes with different SAR threshold requirements.

[0035] In this step, the terminal obtains the status of its modem and / or the environment in which it is located. The terminal's application processor (AP) can activate a modem status monitoring module to monitor the modem's status in real time. The terminal can also identify its environment by monitoring runtime parameters such as its location, network service status, and SIM card characteristics.

[0036] The terminal's scenario refers to its working mode or operating environment at a specific point in time, which can be determined by multi-dimensional data such as hardware status, network connection, application behavior, and user interaction. The terminal's scenario can include various scenarios with different SAR threshold requirements, such as communication scenarios, radio frequency scenarios, user interaction scenarios, and energy-saving scenarios. The SAR threshold represents the safe limit of radio frequency energy absorbed per unit mass of human tissue.

[0037] Step 102: Adjust the terminal's transmit power according to the preset power corresponding to the obtained state and / or scenario, so that the actual SAR value corresponding to the adjusted transmit power is lower than the SAR threshold corresponding to the state and / or scenario.

[0038] In this step, the terminal can determine the preset power level (Device State Index, DSI) corresponding to the acquired state and / or scenario, and send the DSI to the power control module in the terminal. The power control module can determine the preset power corresponding to the state and / or scenario based on the received DSI, and adjust the terminal's transmission power accordingly.

[0039] Among them, the preset power is the radio frequency transmission power that the device is set in advance in different scenarios. It can represent the power adjustment value of the transmission power or the target power value of the transmission power.

[0040] The terminal's transmit power can be adjusted according to the preset power corresponding to the modem's status, so that the actual SAR value corresponding to the adjusted transmit power is lower than the SAR threshold corresponding to the modem's status.

[0041] The terminal's transmit power can also be adjusted according to the preset power corresponding to the scene in which the terminal is located, so that the actual SAR value corresponding to the adjusted transmit power is lower than the SAR threshold corresponding to the scene in which the terminal is located.

[0042] If the modem status and the terminal's current scenario are obtained, the transmission power adjustment method can be determined based on the priority of the preset power corresponding to the modem status and the terminal's current scenario. In one embodiment, the transmission power can be adjusted as follows: if the modem status is normal, the transmission power is adjusted according to the preset power corresponding to the terminal's current scenario; if the modem status is abnormal, the transmission power is adjusted to the preset power corresponding to the abnormal status.

[0043] The normal state reflects the modem's normal operation, while the abnormal state reflects the modem's inability to operate normally. Abnormal states can include crashes, failed reboots, etc. The preset power for abnormal states can be lower than the preset power for the scenario in which the terminal is located.

[0044] For example, Figure 2 A flowchart of a method for adjusting transmission power is shown. The method may include the following steps:

[0045] Step 201: Monitor the status of the modem.

[0046] In this step, after the terminal is powered on, the module on the AP side that monitors the modem status is activated. This module can monitor the modem status in real time.

[0047] Step 202: Determine if the status is normal.

[0048] If the modem is running normally, the status is determined to be normal, and step 203 is continued;

[0049] If the modem crashes or fails to operate normally, the status is determined to be abnormal, and step 204 is executed.

[0050] Step 203: Adjust the transmission power according to the preset power corresponding to the scenario in which the terminal is located.

[0051] In this step, if the modem is in normal condition, the transmission power can be adjusted according to the preset power corresponding to the scenario in which the terminal is located.

[0052] Step 204: Adjust the transmission power to the preset power corresponding to the abnormal state.

[0053] In this step, if the modem is in an abnormal state, the transmission power can be adjusted to the preset power corresponding to the abnormal state.

[0054] As mentioned above, by establishing state priority adjustment rules, it is ensured that the handling of modem malfunctions takes precedence over routine scenario adjustments, preventing the spread of radiation risks caused by system failures, while maintaining dynamic optimization space under normal conditions.

[0055] The specific absorption rate (SAR) control method in this embodiment obtains the state of the terminal's modem and / or the scene in which the terminal is located. Based on the preset power corresponding to the obtained state and / or scene, the transmit power of the terminal is adjusted so that the actual SAR value corresponding to the adjusted transmit power is lower than the SAR threshold corresponding to the state and / or scene. Through the perception and adjustment mechanism of the modem state and / or the scene in which the terminal is located, precise power control based on dynamic environmental requirements is achieved, ensuring that the actual SAR value meets the SAR safety standard under different conditions, thereby protecting human safety and achieving a balance between compliance assurance and communication performance optimization.

[0056] In the foregoing embodiments, a collaborative mechanism of modem status monitoring and terminal scene identification was introduced to achieve SAR dynamic control. In the following embodiments, the power adjustment process under modem status will be described in more detail, and this method can be applied to any of the embodiments described above.

[0057] In one embodiment, if the modem is in a normal state, it is determined whether the normal state will switch to a crash state. If the normal state switches to a crash state, the transmit power is adjusted to a preset power corresponding to the crash state to reduce the actual SAR value in the crash state.

[0058] The terminal can monitor the modem's status by acquiring data such as the modem's heartbeat packets and the baseband processor's operating logs. If the data response and verification are normal, the modem's status can be determined to be normal.

[0059] While the modem is in a normal state, continuously monitor its status to determine if it has switched from a normal state to a crash state. If heartbeat packet loss is detected for a period of time (e.g., 10 seconds), the baseband processor watchdog timer is triggered to reset, or the number of I2C bus errors reported by the RF front end exceeds the threshold, it can be determined that the normal state has switched to a crash state.

[0060] As mentioned above, by establishing a rapid response mechanism for the high-risk scenario of modem crash, and by switching preset power in real time to avoid SAR exceeding the standard due to system malfunction, the radiation safety protection level in the crash state is improved.

[0061] In one embodiment, if the modem is in a crash state, it can be determined whether the modem's state has switched to a restart failure state.

[0062] If the modem status switches to a restart failure state, the transmit power is adjusted to the preset power corresponding to the restart failure state; if the modem status switches to a normal state, the transmit power is adjusted according to the preset power corresponding to the working state of the SAR sensor.

[0063] The operating state of the SAR sensor can include a triggered state and a non-triggered state. The criteria for determining a restart failure state can include at least one of the following: the modem state has not changed, or the modem has not reset the SAR sensor's operating state to the non-triggered state.

[0064] For example, if the modem is in a crashed state, the terminal initiates the modem's automatic restart mechanism, setting the SAR sensor's operating state to triggered. If the modem restarts successfully, the SAR sensor's operating state should be automatically reset to non-triggered. The terminal determines whether the modem's state has switched to a restart failure state by monitoring the modem's restart result.

[0065] If the modem's state does not change within the first preset time period, and / or the modem does not reset the SAR sensor's operating state within the second preset time period, it can be determined that the modem restart has failed, and the modem's state switches to the restart failure state. The transmit power can then be adjusted to the preset power corresponding to the restart failure state.

[0066] If the modem's state changes within the first preset time period, and the modem resets the SAR sensor's operating state within the second preset time period, restoring the SAR sensor's operating state from the triggered state to the non-triggered state, it can be determined that the modem restarted successfully, and the modem's state switched to normal. The transmission power can be adjusted according to the preset power corresponding to the SAR sensor's operating state.

[0067] As described above, by adopting a hierarchical anomaly handling strategy, a more stringent power lock is implemented for restart failure states. At the same time, by linking the working status of SAR sensors, the continuity of the power strategy after system recovery is ensured, forming a complete anomaly handling chain from crash detection to recovery monitoring.

[0068] In one embodiment, the preset power corresponding to the restart failure state can be lower than the preset power corresponding to the crash state. For example, the preset power corresponding to the crash state can be the preset power corresponding to the trigger state. When the modem's state switches to the crash state, the transmit power can be adjusted to the preset power corresponding to the trigger state. After switching to the crash state, if a modem restart failure is detected, the transmit power can be adjusted to the preset power corresponding to the restart failure state to further reduce the actual SAR value.

[0069] As described above, by establishing a power gradient control system for crash and restart failure states, and by employing a progressively stronger power back-off strategy to address system failures of varying severity, a precise match between risk level and power limitation intensity can be achieved.

[0070] To further explain the power adjustment process in the modem's state, Figure 3 A flowchart of a power adjustment method for a modem in a given state is shown. The method may include the following steps:

[0071] Step 301: Monitor the status of the modem.

[0072] In this step, the AP side in the terminal can monitor the status of the modem.

[0073] Step 302: Determine if the status is normal.

[0074] In this step, the AP side continuously monitors whether the modem is operating normally and determines whether the status is normal.

[0075] If the modem crashes, determine that the modem is in a crashed state and continue to step 303;

[0076] If the modem is running normally, then the modem status is determined to be normal, and step 307 is executed.

[0077] Step 303: Activate the modem's automatic restart mechanism.

[0078] In this step, the modem's automatic restart mechanism can be activated, the SAR sensor's operating state can be set to the triggered state, and the transmit power can be adjusted to the preset power corresponding to the triggered state to reduce the actual SAR value.

[0079] Step 304: Determine if the state has changed.

[0080] In this step, the AP side can determine whether the status of the modem has changed within the first preset time period.

[0081] If the status of the modem changes, proceed to step 305;

[0082] If the modem status has not changed, proceed to step 306.

[0083] Step 305: Determine whether the working status of the SAR sensor has been reset.

[0084] In this step, the AP side can determine that the modem has reset the SAR sensor's working state to the non-triggered state within the second preset time period.

[0085] If the SAR sensor's operating status has been reset, proceed to step 307;

[0086] If the SAR sensor's operating status has not been reset, proceed to step 306.

[0087] Step 306: Adjust the transmission power to the preset power corresponding to the restart failure state.

[0088] In this step, it can be determined that the modem has failed to restart, and the modem's state has switched to a restart failure state. The SAR processing (SAR algo) module in the terminal can send the DSI of the preset power corresponding to the restart failure state to the power control module. The power control module can determine the preset power corresponding to the restart failure state based on this DSI and adjust the transmit power to the preset power corresponding to the restart failure state.

[0089] Step 307: Adjust the transmission power according to the preset power corresponding to the working state of the SAR sensor.

[0090] In this step, it can be confirmed that the modem has successfully restarted and its status has switched to normal. The modem can detect the operating status of the SAR sensor and send the DSI of the preset power corresponding to the SAR sensor's operating status to the power control module. The power control module can determine the preset power corresponding to the SAR sensor's operating status based on this DSI, and adjust the transmission power accordingly.

[0091] For example, if a human body approaches the terminal, the SAR sensor enters a triggered state. The modem can send a DSI (Diverterless Supersonic Indicator) at a preset power corresponding to this triggered state to the power control module. The power control module can then adjust the transmission power to the preset power corresponding to the triggered state based on this DSI.

[0092] If the human body is far from the terminal, the SAR sensor operates in a non-triggered state. The modem can send the DSI (Diverterless Supersonic Indicator) of the preset power corresponding to the non-triggered state to the power control module. The power control module can adjust the transmission power to the preset power corresponding to the non-triggered state based on this DSI. The preset power corresponding to the triggered state can be lower than the preset power corresponding to the non-triggered state.

[0093] Understandable. Figure 3 The power adjustment process shown is merely an example and can be expanded or optimized according to actual application needs. For instance, after a successful modem restart, the transmit power can be dynamically optimized based on the terminal's scenario (such as a communication scenario or a user interaction scenario). Alternatively, a multi-level fault diagnosis mechanism can be introduced during the crash detection phase, matching differentiated preset power levels according to different crash types (such as hardware failures or software deadlocks). Furthermore, after a modem restart failure, the user interface can display abnormal status messages and suggest safe operations, etc. This application does not limit these aspects.

[0094] In the foregoing embodiments, a three-level state transition strategy of "normal state - crash state - restart failure state" was constructed through multi-level state monitoring and power linkage mechanism, forming a strict correspondence between risk level and power limit to realize modem anomaly handling. In the following embodiments, the power adjustment process in the scenario in which the terminal is located will be described in more detail, and it can be applied to any of the above embodiments.

[0095] In one embodiment, it can be determined whether the terminal is in a SAR-limited scenario. If the terminal is in a SAR-limited scenario, it is then determined whether the terminal is in a real-time communication scenario.

[0096] SAR-constrained scenarios are those requiring increased transmit power, such as communication and user interaction scenarios. Real-time communication scenarios, on the other hand, require reduced transmit power, such as high-temperature scenarios, SAR testing scenarios, and low-battery scenarios. The SAR threshold for real-time communication scenarios is higher than that for SAR-constrained scenarios.

[0097] If the terminal is not in a SAR-limited scenario, the transmission power is adjusted to the first preset power; if the terminal is in a SAR-limited scenario and not in a real-time communication scenario, the transmission power is adjusted to the second preset power; if the terminal is in a SAR-limited scenario and in a real-time communication scenario, the transmission power is adjusted to the third preset power.

[0098] Among them, the third preset power is greater than or equal to the first preset power, and the first preset power is greater than the second preset power.

[0099] For example, the first preset power can be equal to the third preset power. The first preset power and the third preset power can be the power values ​​obtained by subtracting the first power reduction value from the full power value, and the second preset power is the power value obtained by subtracting the second power reduction value from the full power value.

[0100] Full power is the maximum transmit power that the terminal radio frequency system can achieve within the limits allowed by hardware and protocols. The first power reduction can be less than or equal to the second power reduction.

[0101] For example, the terminal can continuously monitor its operating environment parameters and determine whether it is in a SAR-limited scenario based on these parameters. If the terminal is not in a SAR-limited scenario, it is determined that the scenario does not require a reduction in transmission power, and the transmission power can be adjusted to a higher first preset power to ensure the terminal's communication quality.

[0102] If the terminal is in a SAR-limited scenario, and the scenario necessitates reduced transmit power, it is necessary to further determine whether the terminal is in a real-time communication scenario. The determination of a real-time communication scenario can be achieved, for example, by detecting an application with communication capabilities running in the foreground; or by using network service data (such as QCI parameters, port number characteristics, RTP payload) and radio frequency layer scheduling information (such as L1 / L2 HARQ retransmission rate, scheduling request frequency), etc.

[0103] If the terminal is in a SAR-limited scenario and not in a real-time communication scenario, and it is determined that the scenario in which the terminal is located does not require an increase in transmission power, the transmission power can be adjusted to a lower second preset power, thereby reducing the transmission power and the actual SAR value.

[0104] If the terminal is in a SAR-limited scenario and a real-time communication scenario, the requirement to increase the transmission power can be prioritized, and the transmission power can be adjusted to a higher third preset power to ensure the communication quality of the terminal.

[0105] As described above, by first determining whether the terminal is in a SAR-limited scenario, and then further distinguishing between real-time and non-real-time communication scenarios, the transmission power is dynamically adjusted: a higher first preset power is used in non-SAR-limited scenarios to ensure communication quality; in SAR-limited but non-real-time communication scenarios, the power is reduced to a second preset power to reduce radiation exposure; and in SAR-limited but real-time communication scenarios, a third preset power of no less than the first preset power is allowed to be used, prioritizing the smoothness of critical services such as voice and video. Through the hierarchical power control strategy, communication performance and user experience are optimized while ensuring radiation safety requirements.

[0106] In one embodiment, if the terminal is in a real-time communication scenario, the uplink transmission data of the terminal is monitored. If uplink transmission data is continuously monitored within a preset time period, it is determined that the terminal is in an uplink data transmission scenario.

[0107] Uplink data transmission scenarios are communication scenarios where the terminal actively sends data to the network, such as message sending, audio calls, and file synchronization. Uplink transmitted data refers to user-oriented data such as data traffic, messages, and files generated by user-initiated or direct interaction.

[0108] If the terminal is in a SAR-limited scenario and in an uplink data transmission scenario, the transmit power will be adjusted to the third preset power; if the terminal is in a SAR-limited scenario and not in an uplink data transmission scenario, the transmit power will be adjusted to the second preset power.

[0109] For example, if the terminal is in a real-time communication scenario, it can continuously monitor its uplink transmission data. If uplink transmission data is continuously monitored within a preset time period, it is determined that the terminal is in an uplink data transmission scenario.

[0110] If the terminal is in a SAR-limited scenario and in an uplink data transmission scenario, the transmission power will be adjusted to the third preset power to ensure that the terminal maintains a high transmission power and avoids problems such as lag and disconnection caused by SAR limitation, thereby ensuring the communication quality of the terminal.

[0111] If no uplink data is continuously detected within the preset time period, it can be determined that the terminal is not in an uplink data transmission scenario. If the terminal is in a SAR-limited scenario and not in an uplink data transmission scenario, the transmit power can be adjusted to a lower second preset power to reduce the transmit power and the actual SAR value.

[0112] As described above, when the terminal is in a SAR-limited scenario, if continuous uplink data transmission is detected, a higher third preset power is maintained to ensure communication quality; if there is no continuous uplink data transmission, the power is adjusted to a lower second preset power to reduce radiation exposure. Through a dynamic power adjustment mechanism based on data stream characteristics, energy efficiency is optimized while ensuring service performance, avoiding communication quality degradation or unnecessary radiation risks caused by scenario misjudgment, thereby improving the accuracy of transmit power control.

[0113] In one embodiment, it can be determined whether the terminal is in a SAR-limited scenario based on at least one of the terminal's application data, network service data, and radio frequency operational data. The application data refers to the software and hardware status information running on the terminal, and may include application lists, location information, contact information, call log information, battery level information, terminal temperature, etc.

[0114] Network service data refers to status information related to network connectivity and data transmission. This can include network service status, Public Land Mobile Network (PLMN) status, user data usage progress information, and user plane uplink and downlink data throughput. Radio frequency (RF) operational data refers to real-time operating parameters of the terminal's RF system. This can include SIM card feature file information, network characteristics, L2 / L1 scheduling information, and RF transmit power information.

[0115] For example, the terminal temperature can be obtained, and if the terminal temperature exceeds a preset temperature threshold, it can be determined that the terminal is in a SAR-limited scenario; the terminal battery information can also be obtained, and if the battery information exceeds a preset battery threshold, it can be determined that the terminal is in a SAR-limited scenario, and so on.

[0116] Based on SIM card data in network service data and radio frequency operational data, it can be determined whether the terminal is in a real-time communication scenario. For example, based on SIM card data in network service data and radio frequency operational data, it can be determined that the SIM card in the terminal is a test blank card (such as a laboratory test card, an engineering mode dedicated card, etc.). Since such SIM cards are usually used in non-real user scenarios, it can be determined that the terminal is not in a real-time communication scenario.

[0117] As mentioned above, by constructing intelligent decision-making based on multi-source data fusion, the accuracy of scenario determination is improved by cross-validation of data from the application layer, network layer, and radio frequency layer. At the same time, the accuracy of identifying non-real-time communication scenarios is enhanced by utilizing the hardware-level features of the SIM card.

[0118] To further explain the power adjustment process in the scenario in which the terminal is located Figure 4 A flowchart of a power adjustment method for a terminal in a given scenario is shown. The method may include the following steps:

[0119] Step 401: Monitor the terminal's operating environment parameters.

[0120] In this step, after the terminal is powered on, the modem is in a normal state, and the ModemLabflag module in the modem is enabled. The ModemLabflag module can monitor the terminal's application data, network service data, and radio frequency operating status data, as well as other operating environment parameters.

[0121] Step 402: Determine whether the terminal is in a SAR-restricted scenario.

[0122] In this step, the Modem Labflag module can determine whether the terminal is in a SAR-restricted scenario based on operating environment parameters such as terminal application data, network service data, and radio frequency operating status data.

[0123] If the terminal is in a SAR-restricted scenario, continue to step 403;

[0124] If the terminal is not in a SAR-restricted scenario, proceed to step 409.

[0125] Step 403: Determine whether the terminal is in a real-time communication scenario.

[0126] In this step, the SIM card data in the network service data and radio frequency operation data can be used to determine whether the terminal is in a real-time communication scenario.

[0127] If the terminal is in a SAR-restricted scenario and a real-time communication scenario, then continue to step 404;

[0128] If the terminal is in a SAR-restricted scenario and not in a real-time communication scenario, then proceed to step 408.

[0129] Step 404: Determine whether the data monitoring module is enabled.

[0130] In this step, it can be determined whether the data monitoring (TX Monitor) module in the terminal is enabled. The data monitoring module can be used to detect whether there is uplink data transmission.

[0131] If the data monitoring module is not enabled, proceed to step 405;

[0132] If the data monitoring module is already enabled, proceed to step 406.

[0133] Step 405: Enable the data monitoring module.

[0134] Step 406: Determine whether uplink transmission data has been detected.

[0135] In this step, it can be determined whether the data monitoring module has detected uplink transmission data within a preset time period.

[0136] If uplink data is detected, it is determined that the terminal is in a SAR-limited scenario and an uplink data transmission scenario, and step 407 is executed.

[0137] If no uplink data is detected, it is determined that the terminal is in a SAR-restricted scenario and not in an uplink data transmission scenario, and step 408 is executed.

[0138] Step 407: Adjust the transmission power to the third preset power.

[0139] In this step, if the terminal is in a SAR-limited scenario and is transmitting uplink data, the modem can send the DSI corresponding to the third preset power to the power control module. The power control module can determine the third preset power based on this DSI and adjust the transmit power to the third preset power.

[0140] Step 408: Adjust the transmission power to the second preset power.

[0141] In this step, if the terminal is in a SAR-limited scenario and not in a real-time communication scenario, or if the terminal is in a SAR-limited scenario and not in an uplink data transmission scenario, the modem can send the DSI corresponding to the second preset power to the power control module. The power control module can determine the second preset power based on the DSI and adjust the transmit power to the second preset power.

[0142] Step 409: Adjust the transmission power to the first preset power.

[0143] In this step, if the terminal is not in a SAR-limited scenario, the modem can send the DSI corresponding to the first preset power to the power control module. The power control module can determine the first preset power based on the DSI and adjust the transmit power to the first preset power.

[0144] Understandable Figure 4 The power adjustment process shown is just an example and can be extended or optimized according to actual application needs. For example, when emergency communication (such as emergency calls, SOS signals, etc.) is detected, the transmission power can be directly adjusted to the third preset power; another example is that a data traffic threshold mechanism can be introduced in step 406, so that when the uplink transmission data is lower than a certain threshold, it is still considered that there is no uplink data transmission scenario, so as to further reduce the actual SAR value; yet another example is that user behavior analysis (such as screen activation status, sensor data, etc.) can be combined to assist in the determination of real-time communication scenarios, or a whitelist mechanism can be set for specific applications (such as medical device networking) to maintain a higher transmission power, etc. This application embodiment does not limit these aspects.
