DETAILED DESCRIPTION

[0015] The embodiments of the present application provide a method and device for terminal device working, a terminal device and a storage medium, which are used for calling different target tuning parameter tables when it is detected that the terminal device is in different target scenes, and then selecting target tuning parameters for working according to the corresponding tuning parameter tables, so that the best performance of the terminal device in different target scenes can be ensured.

[0016] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all should belong to the scope of protection of the present application.

[0017] First, some terms related to the present application will be briefly described as follows: 1. AOL (Antenna Open Loop) is a kind of antenna tuning method. The system switches the tuning state (such as impedance matching) of the antenna according to the preset conditions (such as a specific frequency band, a communication mode or a state of a user holding the mobile phone). It is a feedforward system, and its tuning decision does not depend on real-time monitoring of the performance of the antenna.

[0018] The working principle is as follows: Preset strategy: Before the mobile phone is shipped, the mobile phone manufacturer will perform a large number of tests to establish a "lookup table". The table records the optimal antenna tuner settings (such as capacitance value) in different scenes (such as starting 4G Band 3 frequency band, user holding the mobile phone with left hand, starting Wireless Fidelity (Wi-Fi) hotspot, etc.).

[0019] Scene judgment: The system monitors the working state of the mobile phone (the currently used frequency band, the power level, the sensor data such as the proximity sensor to judge the holding mode, etc.) in real time.

[0020] Execution of tuning: The system directly calls the preset tuning scheme from the lookup table according to the monitored state, and instructs the antenna tuner (usually a variable capacitor or a switch chip) to switch.

[0021] No feedback verification: After the tuning is completed, the system does not detect the actual performance of the antenna (such as whether the impedance matching is really optimal, whether the signal quality is improved).

[0022] 2. ACL (Antenna Closed Loop) is a more advanced antenna tuning method. It dynamically and precisely adjusts the tuner by monitoring a key parameter of the antenna system (such as reflected power or impedance) in real time and using this as a feedback signal to keep the antenna in optimal operating condition. It is a feedback control system.

[0023] Working principle: Monitoring: The system continuously measures the forward power from the power amplifier output to the antenna and the reflected power from the antenna using a detection element such as a directional coupler.

[0024] Calculation and Comparison: The system calculates the voltage standing wave ratio (VSWR) or return loss based on the forward and reflected power. These parameters directly reflect the quality of antenna impedance matching.

[0025] Decision and Adjustment: The system (or dedicated tuning chip) algorithm continuously fine-tunes the antenna tuner settings with the goal of minimizing reflected power (i.e. optimizing impedance matching to make VSWR as close to 1:1 as possible).

[0026] Closed-loop feedback: This is a continuous closed-loop process of "monitoring-calculation-adjustment-verification" to ensure that the antenna maintains high performance in any operating environment.

[0027] 3. SAR (Specific Absorption Rate): SAR is a safety standard used to measure the rate at which body tissues absorb radio frequency energy when exposed to electromagnetic fields (such as radio frequency radiation from mobile phones). Its unit is watts per kilogram (W / kg). For example, mobile phones have a built-in SAR sensor mechanism. When the phone detects that it is very close to the human body (e.g., held to the ear during a call, or placed in a pocket), the system will actively reduce the antenna's transmit power (TX Power) to ensure that the SAR value does not exceed the legal limit. This is a mandatory safety measure to protect user health.

[0028] 4. DSI (Dynamic Sensor Input / Dynamic State Indication): DSI is a set of information used by a mobile phone system to determine the current usage state of the device. It is not a single sensor, but a decision-making logic whose input information can come from multiple sensors and system states. Common DSI input sources include: Proximity sensor: Determines whether the phone is close to a person's face or body.

[0029] Accelerometer / Gyroscope: Determine whether the phone is in hand, stationary, or in pocket, etc.

[0030] Touch screen event: Determine whether the user is operating the phone.

[0031] Application status: Such as whether the camera is on, the status of the cellular network, etc.

[0032] In a terminal device, the camera and cellular communication are two independent modules. In a specific scenario, such as when the camera is turned on for taking a photo or video, and the terminal device is in a weak signal scenario, the transmit (TX) power is high, and if the TX antenna corresponding to the registered frequency band is close to the camera, the high power of the cellular at the TX antenna in this scenario will interfere with the operation of the camera, causing the camera to freeze or have a distorted screen, seriously affecting the user's normal use of the camera and bringing about a poor user experience. Figure 1 As shown in FIG. 1, which is a schematic diagram of the layout of an antenna and a camera lens included on a terminal device, the antenna (ANT) 10 is a transmit antenna.

[0033] The existing scheme for avoiding camera interference is that when the camera detects Mobile Industry Processor Interface (MIPI) interference, it sends a broadcast message to inform the cellular to perform corresponding processing, such as reducing the transmit power of the interference frequency band to the maximum transmission power limit (MTPL), or switching the TX transmit antenna when the camera is working, that is, switching the TX transmit antenna of the interference frequency band to another antenna that does not interfere.

[0034] The existing maximum transmission power limit (MTPL) of the interference frequency band is applicable to all terminal devices. The MTPL is the minimum MTPL obtained through laboratory testing. After setting the MTPL, the normal use of the camera application can be guaranteed, but the TX performance of the cellular is affected, resulting in abnormal communication functions of the terminal device in a weak signal due to the inability to increase the TX power.

[0035] In the embodiments of the present application, when it is detected that the terminal device is in different target scenarios, different target tuning parameter tables can be called, and then target tuning parameters can be selected for work according to the corresponding tuning parameter table, which can ensure the best performance of the terminal device in different target scenarios.

[0036] In the embodiments of the present application, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self driving, a wireless terminal device in remote medical treatment, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, or a wireless terminal device in smart home, etc.

[0037] By way of example and not limitation, in the embodiments of the present application, the terminal device can also be a wearable device with a display interface. The wearable device can also be referred to as a wearable smart device, which is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes, etc. The wearable device is a portable device that can be directly worn on the body or integrated into the clothes or accessories of the user. The wearable device is not only a hardware device, but also a device that realizes powerful functions through software support and data interaction and cloud interaction. The wearable smart device in a broad sense includes devices with full functions, large size, and the ability to realize complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, etc., and devices that focus on a certain type of application function and need to be used in cooperation with other devices, such as smart phones, such as various smart wristbands and smart jewelry for monitoring vital signs, etc.

[0038] The technical solutions of the present application are further described below by way of examples, such as the flowchart of the method for the camera application program to work in the embodiments of the present application, as shown in FIG. 1, which can include the following steps: Figure 2 201, in the case where it is detected that the terminal device is in a target scene, a target tuning parameter table corresponding to the target scene is called.

[0039] The target scene is a scene in which the camera application program is in an open state and registers a cellular frequency band, or a scene in which the camera application program is in a closed state and registers the cellular frequency band (it can also be understood as a scene in which the camera application program is switched from an open state to a closed state and registers the cellular frequency band), or a scene in which the camera application program is in an open state and does not register the cellular frequency band.

[0040] ​Exemplarily, in a case where it is detected that the terminal device is in a target scenario, a target tuning parameter table corresponding to the target scenario is invoked. That is, in a case where it is detected that the terminal device is in a scenario in which the camera application is in an open state and the cellular frequency band is registered, which can also be referred to as a first target scenario, a first target tuning parameter table corresponding to the scenario in which the camera application is in an open state and the cellular frequency band is registered is invoked; in a case where it is detected that the terminal device is in a scenario in which the camera application is in a closed state and the cellular frequency band is registered, which can also be referred to as a second target scenario, a second target tuning parameter table corresponding to the scenario in which the camera application is in a closed state and the cellular frequency band is registered is invoked; in a case where it is detected that the terminal device is in a scenario in which the camera application is in an open state and the cellular frequency band is not registered, which can also be referred to as a third target scenario, a third target tuning parameter table corresponding to the scenario in which the camera application is in an open state and the cellular frequency band is not registered is invoked.

[0041] In some possible implementation manners of the present application, in a case where it is detected that the terminal device is in a first target scenario, invoking a first target tuning parameter table corresponding to the first target scenario can comprise: in a case where it is detected that the terminal device is in the first target scenario and the communication quality of the cellular frequency band is less than a quality threshold, invoking the first target tuning parameter table corresponding to the first target scenario.

[0042] Exemplarily, in the case that it is detected that the terminal device is in a scenario where the camera application is in an open state and the cellular frequency band is registered, if it is further detected that the communication quality of the terminal device is less than the quality threshold, that is, the terminal device is in a weak signal scenario, at this time, the first target tuning parameter table corresponding to the first target scenario can be called, and then the first target tuning parameter is selected from the first target tuning parameter table to reduce the transmission power of the transmission antenna. For example, the communication quality of the terminal device being less than the quality threshold can include that the terminal device detects that the signal strength of the registered cellular frequency band is very low (RSRP (Reference Signal Received Power, reference signal received power) / RSRQ (Reference Signal Received Quality, reference signal received quality) value difference), or the signal quality is very poor (low signal-to-noise ratio, large interference), which causes the terminal device to be unable to stably connect to the network, which is manifested as slow network speed, intermittent or dropped calls, etc. At this time, the high transmission power of the transmission antenna of the terminal device will affect the use of the camera application, and the influence on the use of the camera application can be reduced by calling the first target tuning parameter table corresponding to the first target scenario, and then selecting the first target tuning parameter in the first target tuning parameter table, and reducing the transmission power of the transmission antenna of the terminal device according to the first target tuning parameter, so as to subsequently transmit signals according to the reduced transmission power.

[0043] In the technical solution, in the case that it is detected that the terminal device is in a scenario where the camera application is in an open state and the cellular frequency band is registered, and the communication quality of the cellular frequency band is less than the quality threshold, the first target tuning parameter table corresponding to the first target scenario is called, so as to subsequently reduce the transmission power of the transmission antenna by selecting the first target tuning parameter in the first target tuning parameter table, obtain the reduced transmission power, and then transmit signals according to the reduced transmission power, which can ensure the transmission power of the transmission antenna to a certain extent, and can reduce the interference on the use of the camera application on the terminal device.

[0044] In some possible implementation manners of the present application, in the case that it is detected that the terminal device is in the first target scenario, calling the first target tuning parameter table corresponding to the first target scenario can include: in the case that it is detected that the terminal device is in the first target scenario, and the distance between the transmission antenna corresponding to the cellular frequency band and the camera lens is less than the distance threshold, the first target tuning parameter table corresponding to the first target scenario is called.

[0045] For example, in the case of detecting that the terminal device is in a scenario where the camera application is in an open state and a cellular frequency band is registered, if it is further detected that the distance (generally understood as the straight-line distance) between the transmitting antenna corresponding to the registered cellular frequency band of the terminal device and the camera lens is less than a distance threshold, because the distance between the transmitting antenna and the camera lens is too close, the transmitting power of the transmitting antenna will interfere with the operation of the camera application. At this time, the first target tuning parameter table corresponding to the first target scenario can be called, and then the first target tuning parameter is selected from the first target tuning parameter table to reduce the transmitting power of the transmitting antenna. That is, the influence on the use of the camera application can be reduced by reducing the transmitting power of the transmitting antenna of the terminal device.

[0046] In the technical solution, in the case of detecting that the terminal device is in a scenario where the camera application is in an open state and a cellular frequency band is registered, and the distance between the transmitting antenna corresponding to the cellular frequency band and the camera lens is less than a distance threshold, the first target tuning parameter table corresponding to the first target scenario can be called, and then the first target tuning parameter is selected from the first target tuning parameter table to reduce the transmitting power of the transmitting antenna of the terminal device according to the first target tuning parameter. Subsequently, signals can be transmitted according to the reduced transmitting power, which can ensure the transmitting power of the transmitting antenna to a certain extent and reduce the interference on the use of the camera application on the terminal device.

[0047] In some possible implementation manners of the present application, in the case of detecting that the terminal device is in the first target scenario, calling the first target tuning parameter table corresponding to the first target scenario can include: in the case of detecting that the terminal device is in the first target scenario, the communication quality of the cellular frequency band is less than a quality threshold, and the distance between the transmitting antenna corresponding to the cellular frequency band and the camera lens is less than a distance threshold, calling the first target tuning parameter table corresponding to the first target scenario.

[0048] Exemplarily, in the case that it is detected that the terminal device is in a scenario where the camera application is in an open state and a cellular frequency band is registered, if it is further detected that the communication quality of the terminal device is less than a quality threshold, that is, the terminal device is in a weak signal scenario, and it is detected that the distance (generally understood as the straight-line distance) between the transmitting antenna corresponding to the cellular frequency band registered by the terminal device and the camera lens is less than a distance threshold, because the distance between the transmitting antenna and the camera lens is too close, in the weak signal scenario, the high transmission power of the transmitting antenna to transmit signals will interfere with the operation of the camera application, at this time, the first target tuning parameter table corresponding to the first target scenario can be called, and then the first target tuning parameter is selected from the first target tuning parameter table to reduce the transmission power of the transmitting antenna. That is, the influence on the use of the camera application can be reduced by reducing the transmission power of the transmitting antenna of the terminal device.

[0049] In the technical solution, in the case that it is detected that the terminal device is in a scenario where the camera application is in an open state and a cellular frequency band is registered, the communication quality of the cellular frequency band is less than a quality threshold, and the distance between the transmitting antenna corresponding to the cellular frequency band and the camera lens is less than a distance threshold, the first target tuning parameter table corresponding to the first target scenario is called, and then the first target tuning parameter is selected from the first target tuning parameter table to reduce the transmission power of the transmitting antenna, to obtain the reduced transmission power, so that the signal is transmitted according to the reduced transmission power subsequently, which can ensure the transmission power of the transmitting antenna to a certain extent and can reduce the interference on the use of the camera application on the terminal device.

[0050] In some possible implementation manners of the present application, before the target tuning parameter table corresponding to the target scenario is called in the case that it is detected that the terminal device is in the target scenario, the method further includes: setting the corresponding target tuning parameter table according to different target scenarios in which the terminal device is located.

[0051] Exemplarily, before the target tuning parameter table corresponding to the target scenario is called in the case that it is detected that the terminal device is in the target scenario, the corresponding target tuning parameter table can be set according to different target scenarios in which the terminal device is located, and then the corresponding target tuning parameter table can be called in the case that it is detected that the terminal device is in different target scenarios subsequently, and then the target tuning parameter is selected, and then the terminal device operates according to the target tuning parameter, to ensure the best performance of the terminal device.

[0052] In the technical solution, the corresponding target tuning parameter table can be set according to different target scenarios in which the terminal device is located, so that the corresponding target tuning parameter table can be called in the case that it is detected that the terminal device is in different target scenarios subsequently, and then the target tuning parameter is selected, to ensure the best performance of the terminal device.

[0053] 202、according to the target tuning parameter table, selecting a target tuning parameter.

[0054] The terminal device selects a target tuning parameter according to the called target tuning parameter table. That is, the target tuning parameter is the best parameter in the target tuning parameter table.

[0055] In a possible implementation, the calling of the target tuning parameter table corresponding to the target scene in the case where it is detected that the terminal device is in the target scene can include: calling the target tuning parameter table corresponding to the target scene in the case where it is detected that the terminal device is in the target scene by using an antenna open loop tuning (AOL) technology. The selecting of the target tuning parameter according to the target tuning parameter table can include: selecting the target tuning parameter according to the target tuning parameter table by using an antenna closed loop tuning (ACL) technology.

[0056] For example, the terminal device can detect whether the terminal device is in a first target scene by using the AOL technology. In the case where it is detected that the terminal device is in the target scene by using the AOL technology, the target tuning parameter can be selected according to the target tuning parameter table by using the ACL technology.

[0057] In the technical solution, whether the terminal device is in the target scene can be detected by using the antenna open loop tuning (AOL) technology, so that the accuracy of detecting that the terminal device is in the target scene is improved, and the feasibility of the solution is improved. The target tuning parameter can be selected according to the target tuning parameter table by using the antenna closed loop tuning (ACL) technology, that is, the ACL technology is used to monitor key parameters (such as reflected power or impedance) of the antenna system in real time, and the parameters are used as feedback signals to dynamically and accurately adjust the tuner, so that the antenna is kept in a good working state, and interference caused by the use of a camera application program is reduced.

[0058] 203、working according to the target tuning parameter.

[0059] The terminal device works according to the target tuning parameter, that is, the performance of the terminal device is in the best state when the tuner is adjusted by using the target tuning parameter.

[0060] In a possible implementation, the target scene is a scene in which a camera application is in an open state and a cellular frequency band is registered; and the working according to the target tuning parameter can include: reducing the transmission power of a transmission antenna according to the target tuning parameter, the reduced transmission power being non-minimum limited transmission power; controlling the transmission antenna to transmit signals according to the reduced transmission power, and working using the camera application, the transmission antenna being an antenna corresponding to the cellular frequency band for transmission.

[0061] For example, when it is detected that the terminal device is in a scene in which a camera application is in an open state and a cellular frequency band is registered, that is, a first target scene, a first target tuning parameter table corresponding to the first target scene can be called, and then, from the first target tuning parameter table, an optimal parameter corresponding to the first target scene can be selected as a first target tuning parameter. The first target tuning parameter can be used to reduce the transmission power of a transmission antenna to obtain a reduced transmission power, and the reduced transmission power is non-minimum limited transmission power. The transmission antenna can be controlled to transmit signals using the reduced transmission power, and the terminal device can work using the camera application. Because the first target scene is a scene in which a camera application is in an open state and a cellular frequency band is registered, the first target tuning parameter table is also a tuning parameter table corresponding to a scene in which a camera application is in an open state and a cellular frequency band is registered. The first target tuning parameter selected from the first target tuning parameter table is also an optimal parameter corresponding to a scene in which a camera application is in an open state and a cellular frequency band is registered. At this time, the transmission power of the transmission antenna is not very low, which can reduce the interference on the camera application and ensure the transmission performance of the transmission antenna.

[0062] When it is detected that the terminal device is in a scene in which a camera application is in an open state and a cellular frequency band is registered, that is, a first target scene, the terminal device can reduce the transmission power of a transmission antenna according to the first target tuning parameter to obtain a reduced transmission power. The transmission antenna is a transmission antenna corresponding to the cellular frequency band registered by the terminal device. The terminal device can detect the open state of the camera application and whether the cellular frequency band is registered at any time, for example, the open state of the camera application can be detected first, and then whether the cellular frequency band is registered can be detected, or whether the cellular frequency band is registered can be detected first, and then the open state of the camera application can be detected, or the open state of the camera application and whether the cellular frequency band is registered can be detected at the same time, which is not limited in the embodiments of the present application.

[0063] In the technical solution, in the case that the target scene is a scene in which the camera application is in an open state and the cellular frequency band is registered, a corresponding target tuning parameter table is called, the key parameters (such as reflected power or impedance) of the antenna system are monitored in real time, and the tuning device is dynamically and accurately adjusted by taking the key parameters as feedback signals, that is, according to the target tuning parameter table, a target tuning parameter is selected, and the transmitting power of the transmitting antenna can be reduced according to the target tuning parameter, so that the transmitting antenna is kept in a good working state, that is, the communication performance of the transmitting antenna can be ensured, and the interference caused by the use of the camera application can be reduced.

[0064] In a possible implementation, the camera application is in a closed state, and the cellular frequency band is registered; and the working according to the target tuning parameter can include: controlling the transmitting antenna to transmit a signal according to the target tuning parameter, the transmitting antenna being an antenna corresponding to the cellular frequency band for transmitting.

[0065] For example, in the case that the terminal device is detected to be in a scene in which the camera application is in a closed state and the cellular frequency band is registered, that is, a second target scene, a second target tuning parameter table corresponding to the second target scene can be called, then, from the second target tuning parameter table, a best parameter corresponding to the second target scene can be selected as a second target tuning parameter, and then the transmitting antenna can be controlled to transmit a signal according to the second target tuning parameter, at this time, the performance of the transmitting antenna is best. Because the second target scene is a scene in which the camera application is in a closed state and the cellular frequency band is registered, the second target tuning parameter table is also a tuning parameter table corresponding to the scene in which the camera application is in a closed state and the cellular frequency band is registered, and then the second target tuning parameter selected from the second target tuning parameter table is also a best parameter corresponding to the scene in which the camera application is in a closed state and the cellular frequency band is registered, so the transmitting antenna is controlled to transmit a signal according to the second target tuning parameter.

[0066] In the technical solution, in the case that the target scene is a scene in which the camera application is in a closed state and the cellular frequency band is registered, a corresponding target tuning parameter table is called, a target tuning parameter is selected according to the target tuning parameter table, and the transmitting antenna can be controlled to transmit a signal according to the target tuning parameter, so that the transmitting power of the transmitting antenna is maximum and the transmitting antenna is kept in an optimal working state, and the communication performance of the transmitting antenna is ensured.

[0067] In some possible implementations of the present application, the controlling the transmitting antenna to transmit a signal according to the target tuning parameter can include: adjusting the transmitting power of the transmitting antenna according to the target tuning parameter to obtain an adjusted transmitting power; and controlling the transmitting antenna to transmit a signal according to the adjusted transmitting power.

[0068] For example, when the terminal device is detected to be in a scenario where the camera application is in a closed state and the cellular frequency band is registered, i.e., the second target scenario, a second target tuning parameter table corresponding to the second target scenario can be called, and then a best parameter corresponding to the second target scenario can be selected from the second target tuning parameter table as a second target tuning parameter. The transmission power of the transmission antenna can be adjusted according to the second target tuning parameter to obtain an adjusted transmission power, and the transmission antenna can be controlled to transmit signals using the adjusted transmission power. The adjustment of the transmission power of the transmission antenna can be an increase or a decrease, which is determined according to actual requirements and is not limited here. Because the second target scenario is the scenario where the camera application is in a closed state and the cellular frequency band is registered, the second target tuning parameter table is also a tuning parameter table corresponding to the scenario where the camera application is in a closed state and the cellular frequency band is registered. The second target tuning parameter selected from the second target tuning parameter table is also a best parameter corresponding to the scenario where the camera application is in a closed state and the cellular frequency band is registered, so that the transmission power of the transmission antenna is maximized, the transmission antenna is kept in an optimal working state, and the communication performance of the transmission antenna is ensured.

[0069] In the technical solution, because the second target scenario is the scenario where the camera application is in a closed state and the cellular frequency band is registered, the second target tuning parameter table corresponding to the second target scenario is called, and the second target tuning parameter selected from the second target tuning parameter table is a best parameter corresponding to the second target scenario. Therefore, the transmission power of the transmission antenna is adjusted according to the second target tuning parameter to obtain an adjusted transmission power, and then the transmission antenna is controlled to transmit signals according to the adjusted transmission power, so that the optimal communication performance of the transmission antenna can be ensured.

[0070] In a possible implementation, the camera application is in an open state and the cellular frequency band is not registered; and the working according to the target tuning parameter can include working using the camera application according to the target tuning parameter.

[0071] For example, when the terminal device is detected to be in the third target scenario, i.e., the camera application is in an open state and no cellular frequency band is registered, a third target tuning parameter table corresponding to the third target scenario can be called, and then a best parameter corresponding to the third target scenario can be selected from the third target tuning parameter table as a third target tuning parameter. The camera application can work according to the third target tuning parameter. Because the third target scenario is the scenario of the camera application being in an open state and no cellular frequency band being registered, the third target tuning parameter table is also a tuning parameter table corresponding to the scenario of the camera application being in an open state and no cellular frequency band being registered. The third target tuning parameter selected from the third target tuning parameter table is also a best parameter corresponding to the scenario of the camera application being in an open state and no cellular frequency band being registered, which can ensure the best performance of the camera application.

[0072] In the technical solution, because the third target scenario is the scenario of the camera application being in an open state and no cellular frequency band being registered, the third target tuning parameter table corresponding to the third target scenario is called, and then the third target tuning parameter selected from the third target tuning parameter table is a best parameter corresponding to the third target scenario. Therefore, the camera application works according to the third target tuning parameter, which can ensure the best performance of the camera application.

[0073] In the embodiment of the present application, the antenna tuning technology (AOL+ACL) can be used to optimize the interference scenario of the camera application. AOL is used to distinguish the scenario of the camera application being in an open state or not, and the scenario of a cellular frequency band being registered or not. ACL is used to subdivide the tunner code of the cellular interference antenna. The tunner code can be compatible with the performance of the cellular antenna, eliminate the interference of the cellular TX antenna on the camera application, greatly guarantee the communication function of the cellular antenna, solve the camera screen flickering and lag problem, and improve the user experience of using the camera application. Figure 3A As shown in the figure, it is a whole framework diagram of reducing the interference on the camera application by the terminal device using the AOL+ACL technology in the embodiment of the present application. The specific implementation is as follows: The terminal device can monitor whether the camera application is in an open state and whether a cellular frequency band is registered in real time through the monitoring module, record whether the camera application of the terminal device is in an open state or a closed state, and record whether a cellular frequency band is registered or not, and notify the processing module to process the state.

[0074] The terminal device selects and calls a preset antenna tuning code table according to the registration of the cellular frequency band and the state of the camera application program through the AOL function of the processing module, and the preset antenna tuning code table is stored in the data module. That is, the data module stores the antenna tuning code table preset in advance. The parameters in the preset antenna tuning code table are set to be different according to whether the device supports the ACL function. The device supporting the ACL function can be subdivided into, for example, 255 tunner code values, and can adapt to a better tunner code according to the scene; and if the device does not support the ACL function, the number of subdivided tunner codes will be less.

[0075] That is, each antenna tuning code table supporting the ACL function can include 255 tunner code values. Each antenna tuning code table not supporting the ACL function can include at least one tunner code value.

[0076] The preset antenna tuning code table includes the scene of registering the cellular frequency band, the scene of the camera application program being in the open state, and the coexistence scene of the camera application program being in the open state + registering the cellular frequency band, and the antenna tuning code table corresponding to the three scenes.

[0077] (1) When the terminal device detects that the camera application program of the terminal device is in the closed state + the scene of registering the cellular frequency band through the monitoring module, the terminal device loads the antenna tuning code table corresponding to the single cellular frequency band according to the scene of registering the cellular frequency band through the processing module, selects the optimal tunner code from the antenna tuning code table corresponding to the single cellular frequency band using the ACL function, and enables the cellular frequency band to be in the best performance state.

[0078] (2) When the terminal device detects that the camera application program of the terminal device is in the open state + the scene of not registering the cellular frequency band through the monitoring module, the terminal device loads the antenna tuning code table corresponding to the open state of the camera application program according to the scene of the camera application program being in the open state through the processing module, selects the optimal tunner code from the antenna tuning code table corresponding to the open state of the camera application program using the ACL function, and enables the camera application program to be in the best working state.

[0079] (3) When the terminal device monitors that the camera application of the terminal device is in an open state + a scenario in which a cellular frequency band is registered through the monitoring module, the processing module loads an antenna tuning code table corresponding to the scenario in which the camera application is in an open state + a cellular frequency band is registered according to the scenario in which the camera application is in an open state + a cellular frequency band is registered, and selects an optimal tunner code from the antenna tuning code table corresponding to the scenario in which the camera application is in an open state + a cellular frequency band is registered using the ACL function. The optimal tunner code can simultaneously compatible with cellular performance and eliminate interference, that is, the optimal tunner code can solve the camera interference problem while guaranteeing the TX performance of the cellular interference frequency band interference antenna.

[0080] Through the above technical solution, the corresponding tunner code table is loaded through AOL scenario recognition, and the optimal tunner code value corresponding to the scenario in which the camera application is in an open state and a cellular frequency band is registered is found according to the ACL function, which can effectively guarantee the normal use of the camera application and provide users with excellent cellular communication use experience, that is, the interference problem of the cellular frequency band on the camera application can be solved.

[0081] As shown in Figure 3B , it is a flowchart for reducing interference on the use of the camera application by the terminal device through AOL + ACL technology in the embodiment of the present application. The terminal device can detect the open state or closed state of the camera application in real time and make corresponding processing.

[0082] When it is monitored that the terminal device does not open the camera application, the tunner code table corresponding to the scenario in which only a cellular frequency band is registered is selected through the AOL function, and the optimal tunner code value corresponding to the registered cellular frequency band and the antenna is selected through the ACL function, to guarantee the communication performance of the cellular.

[0083] For example, as shown in Figure 3CAs shown in FIG. 1, it is a schematic diagram of a scenario in which the camera application in the embodiment of the present application is in an unopened state + one registered cellular frequency band. In the scenario in which the camera application is in an unopened state + one registered cellular frequency band, the registered cellular frequency band is N78 frequency band, wherein in the N78 frequency band, TX / PRX (Physical Receive, continuous reception): ANT10, DRX (Discontinuous Reception, discontinuous reception): ANT6, MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) 1: ANT8, MIMO2: ANT9. The current reference signal received power (Reference Signal Received Power, RSRP) of the N78 frequency band is -110dbm, and the TX power is 26dbm.

[0084] After the technical solution of the present application is processed, the optimal tunner code value in the tunner code table (Table 1) corresponding to the scenario in which the cellular frequency band is registered is selected:

[0085] Table 1 After the technical solution is set, in the N78 frequency band, the TX power of ANT10 can still be maintained at 26dbm, which can effectively guarantee the communication performance of the cellular.

[0086] After the terminal device is monitored to open the camera application, it is further judged whether the terminal device registers the cellular frequency band information. If there is no registered cellular frequency band, the tunner code table corresponding to the scenario in which the single camera application is in an opened state can be selected through the AOL function, and the optimal tunner code value adapted to the camera application in an opened state can be selected through the ACL function, so as to guarantee the working performance of the camera application.

[0087] As shown in FIG. 2, it is a schematic diagram of a scenario in which the camera application in the embodiment of the present application is in an opened state + one registered cellular frequency band. In the scenario in which the camera application is in an opened state + one registered cellular frequency band, the registered cellular frequency band is N78 frequency band, wherein in the N78 frequency band, TX / PRX (Physical Receive, continuous reception): ANT10, DRX (Discontinuous Reception, discontinuous reception): ANT6, MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) 1: ANT8, MIMO2: ANT9. The current reference signal received power (Reference Signal Received Power, RSRP) of the N78 frequency band is -110dbm, and the TX power is 26dbm. Figure 3D As shown in FIG. 3, it is a schematic diagram of a scenario in which the camera application in the embodiment of the present application is in an opened state + one registered cellular frequency band. In the scenario in which the camera application is in an opened state + one registered cellular frequency band, the registered cellular frequency band is N78 frequency band, wherein in the N78 frequency band, TX / PRX (Physical Receive, continuous reception): ANT10, DRX (Discontinuous Reception, discontinuous reception): ANT6, MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) 1: ANT8, MIMO2: ANT9. The current reference signal received power (Reference Signal Received Power, RSRP) of the N78 frequency band is -110dbm, and the TX power is 26dbm.

[0088] After the technical solution of the present application is processed, the optimal tunner code value in the tunner code table (Table 1) corresponding to the scenario in which the cellular frequency band is registered is selected:

[0089]

[0090] Table 2 Once it is detected that the terminal device has opened the camera application and registered the cellular frequency band, the AOL function can be used to select the corresponding tuner code table for the scenario where the camera application is open and the cellular frequency band is registered. Then, the ACL function can be used to select the optimal tuner code value that is suitable for the scenario where the camera application is open and the cellular frequency band is registered. This optimal tuner code value is compatible with the communication performance of the antenna that interferes with the cellular interference frequency band. At the same time, the TX power generated by this optimal tuner code does not interfere with the normal use of the camera, which can effectively ensure that the user can use the camera application normally without affecting the cellular communication performance.

[0091] For example, such as Figure 3E The diagram illustrates a scenario where the camera application is enabled and a cellular band is registered, as shown in this embodiment of the application. In this scenario, where the camera application is enabled and a SIM card is registered on the network, the registered cellular band is the N78 band. The current Reference Signal Received Power (RSRP) of the N78 band is -110 dBm, and the Transmit TX Power is 26 dBm.

[0092] After processing by the technical solution of this application, the optimal tuner code value in the tuner code table (Table 3) corresponding to the scene where the camera application is in the open state and registered with the cellular frequency band is selected to ensure the performance of the camera application.

[0093]

[0094] Table 3 After setting up this technical solution, in the N78 band, the maximum TX transmit power of ANT10 is limited from 26dBm to 20dBm, which can eliminate the TX power interference of cellular N78 ANT10 when taking pictures with camera applications, and can also effectively ensure the communication performance of the cell.

[0095] By processing the above steps, different scenarios can be effectively distinguished and corresponding processing operations can be performed. For example, in scenarios where the camera is not turned on but a cellular frequency band is registered, the camera is turned on but a cellular frequency band is not registered, and the camera is powered on but a cellular frequency band is registered, the corresponding scene's tuner code table is called, and the best-fit tuner code value is selected according to the ACL function. This effectively ensures the cellular communication function, solves the interference of cellular signals to the camera, and provides users with a better user experience.

[0096] In this embodiment, the terminal device can monitor the opening and closing of the camera application and whether it is registered with a cellular frequency band in real time, select the optimal adaptable tuner code value, and enable the normal use of the camera application while ensuring normal cellular communication functions. In scenarios where only a cellular frequency band is registered, AOL+ACL technology is used to select the appropriate tuner code value for the cellular frequency band and antenna to ensure cellular communication performance. In scenarios where only the camera application is open, AOL+ACL technology is used to select the appropriate tuner code value for the camera application to ensure normal camera use. In scenarios where both the camera application is open and a cellular frequency band is registered, AOL+ACL technology is used to select the appropriate tuner code value for both the camera application being open and the cellular frequency band being registered, ensuring the communication performance of the cellular interference frequency band and antenna, while also mitigating interference from the cellular transmit antenna (TX) on the camera application.

[0097] In some possible implementations of this application, the target scenario is a scenario where the camera application is enabled and a cellular frequency band is registered; the method may further include: when the terminal device is detected to be in the target scenario, reducing the transmission power of the transmitting antenna to obtain a reduced transmission power, wherein the reduced transmission power is not a minimum limit transmission power; controlling the transmitting antenna to transmit signals according to the reduced transmission power, and using the camera application to perform operations, wherein the transmitting antenna is the antenna that transmits corresponding to the cellular frequency band.

[0098] For example, in a scenario where the terminal device is detected to be in a state where the camera application is open and a cellular frequency band is registered, i.e., the first target scenario, the transmission power of the transmitting antenna can be reduced to obtain a reduced transmission power, which is not the minimum limit transmission power. Then, the reduced transmission power is used to control the transmitting antenna to transmit signals. At the same time, the terminal device can use the camera application to perform corresponding work. In this case, the transmission power of the transmitting antenna will not be very low, which can reduce interference to the camera application and ensure the transmission performance of the transmitting antenna.

[0099] In this technical solution, the transmitting antenna can also be controlled to transmit signals by reducing its transmission power. The reduced transmission power is not the minimum transmission power limit, so the transmission power of the transmitting antenna will not be very low. This can reduce interference to the camera application and ensure the transmission performance of the transmitting antenna.

[0100] In some possible implementation manners of the present application, the target scene is a scene in which a camera application is in an open state and a cellular frequency band is registered; and the lowering the transmission power of the transmission antenna to obtain the lowered transmission power in the case where it is detected that the terminal device is in the target scene can include: lowering the transmission power of the transmission antenna by a specific absorption rate (SAR) method to obtain the lowered transmission power in the case where it is detected that the terminal device is in the target scene by a dynamic sensor input (DSI) technology.

[0101] Exemplarily, whether the terminal device is in the first target scene, the second target scene, or the third target scene can also be detected by the DSI technology. In the case where the terminal device can continuously monitor the sensor and system state by the DSI technology to detect whether the terminal device is in the scene in which the camera application is in the open state and the cellular frequency band is registered, that is, the first target scene, the transmission power of the transmission antenna can be lowered by the specific absorption rate (SAR) method to obtain the lowered transmission power, and then the transmission antenna can be controlled to transmit signals and the camera application can be controlled to work according to the lowered transmission power.

[0102] In the present technical solution, the terminal device identifies that the first target scene is triggered, that is, the coexistence scene in which the camera application is in the open state and the cellular frequency band is registered, by the DSI technology. The SAR mechanism can be triggered, the terminal device simulates or maps the first target scene as a state in which the radio frequency power needs to be lowered (similar to the safety state of "the mobile phone being close to the human face"), and then the power lowering operation is performed, that is, the SAR control circuit is triggered to instruct the cellular modem to lower the transmission power (TX Power) of the transmission antenna. After the transmission power of the transmission antenna is lowered, the power of the interference source is lowered, and the electromagnetic interference (EMI) caused by the interference source to the camera sensor is also weakened, thereby solving or mitigating the screen flickering and lagging problems.

[0103] The present application embodiment can eliminate the interference of the registered cellular frequency band on the camera application by the tunnercode scheme, and can also eliminate the interference of the registered cellular frequency band on the camera application by the SAR scheme, that is, in the SAR scheme, the scene in which the camera application is in the open state and the cellular frequency band is registered can be added in the DSI identified scene, and the TX antenna of the cellular interference is lowered in power when it is identified that the scene is entered, so as to eliminate the interference on the camera application.

[0104] In some possible implementations of this application, the target scenario is a scenario where the camera application is enabled and a cellular frequency band is registered; the step of reducing the transmission power of the transmitting antenna to obtain the reduced transmission power when the terminal device is detected to be in the target scenario may include: determining a preset step size when the terminal device is detected to be in the target scenario through dynamic sensor input DSI technology; and reducing the transmission power of the transmitting antenna according to the preset step size to obtain the reduced transmission power.

[0105] For example, in a scenario where the terminal device is detected to be in a state where the camera application is turned on and a cellular frequency band is registered, i.e., the first target scenario, by using dynamic sensor input DSI technology, a preset step size can be determined. Then, based on the preset step size, the transmission power of the transmitting antenna can be reduced to obtain the reduced transmission power. Then, based on the reduced transmission power, the transmitting antenna can be controlled to transmit signals, and the camera application can be used to perform operations.

[0106] In this technical solution, when the terminal device is detected to be in the first target scene, a preset step size is determined; according to the preset step size, the transmission power of the transmitting antenna is reduced to obtain the reduced transmission power; then, according to the reduced transmission power, the transmitting antenna is controlled to transmit signals, and at the same time, the camera application is used to perform work (e.g., taking pictures or videos). At this time, the communication performance of the transmitting antenna can be guaranteed, and the interference to the camera application can be reduced.

[0107] In this embodiment, when the terminal device is detected to be in a target scene, a target tuning parameter table corresponding to the target scene is invoked; a target tuning parameter is selected according to the target tuning parameter table; and operation is performed according to the target tuning parameter. The target scene is either a scene where the camera application is enabled and registered with a cellular frequency band, or a scene where the camera application is disabled and registered with the cellular frequency band, or a scene where the camera application is enabled but not registered with the cellular frequency band. This method ensures optimal performance of the terminal device under different target scenes by invoking different target tuning parameter tables and then selecting the target tuning parameter according to the corresponding tuning parameter table.

[0108] like Figure 4 The diagram shown is a schematic representation of an embodiment of the device for operating a terminal device according to this application, which may include: Processing module 401 is configured to, when detecting that the terminal device is in a target scene, call the target tuning parameter table corresponding to the target scene; select target tuning parameters according to the target tuning parameter table; and perform operations according to the target tuning parameters. The target scene is a scene in which a camera application is in an open state and a cellular frequency band is registered, or a scene in which the camera application is in a closed state and the cellular frequency band is registered, or a scene in which the camera application is in the open state and the cellular frequency band is not registered.

The transmitting module 402 is configured to control the transmitting antenna to transmit signals according to the reduced transmitting power, and work using the camera application, wherein the transmitting antenna is an antenna corresponding to the cellular frequency band.

[0115] In some possible implementation manners of the present application, the processing module 401 is specifically configured to reduce the transmitting power of the transmitting antenna by the SAR method to obtain the reduced transmitting power in a case where it is detected by the DSI technology that the terminal device is in the target scenario.

[0116] In some possible implementation manners of the present application, the processing module 401 is specifically configured to determine a preset step length in a case where it is detected by the DSI technology that the terminal device is in the target scenario, and reduce the transmitting power of the transmitting antenna according to the preset step length to obtain the reduced transmitting power.

The touch panel 631, also called a touch screen, can collect a touch operation (such as an operation of a user using a finger, a stylus, or any suitable object or accessory near the touch panel 631) of the user on or near the touch panel 631, and drive a corresponding connection device according to a pre-set program. Optionally, the touch panel 631 can include two parts of a touch detection device and a touch controller.
