In order to explain the technical solutions described in the present application, the following will be described with specific embodiments.

FIG. 1 is a schematic diagram of an implementation process of a method for reducing power consumption provided by an embodiment of the present application. As shown in the figure, the method may include the following steps:

Step S101: After the WIFI function of the terminal device is turned on, monitor the state of the terminal device.

In the embodiment of the present application, a virtual button may be set on the display interface of the terminal device, and the user may select to turn on or off the WIFI function of the terminal device through the virtual button. The state of the terminal device may be the amount of uplink data or downlink data of the terminal device based on the WIFI module, or the type of application running in the foreground of the terminal device, or the display of the terminal device The current state of the screen. No more examples are given here.

In order to reduce power consumption, the embodiments of the present application may set the WIFI module to an intermittent sleep state. When the WIFI module is in the intermittent sleep state, the WIFI module may alternately maintain an active state and a sleep state, for example, active for the first time and sleep for the second Time, active first time, sleep second time, ... Of course, in order to ensure the timeliness of data transmission, the embodiments of the present application also set that after the WIFI module sends a data packet or receives a data packet, it is necessary to maintain an active KAT time (keep time), that is, the KAT time is Describe the time that the WIFI module keeps not sleeping after sending or receiving data packets.

As another embodiment of the present application, after the WIFI function of the terminal device is turned on, the KAT time of the WIFI module of the terminal device is set as the initial time. That is, an initial value is previously set for the KAT time.

Step S102, if the state of the terminal device is the first state, the KAT time of the WIFI module of the terminal device is adjusted to the first time, and the KAT time is that the WIFI module remains dormant after sending or receiving a data packet time.

In the embodiment of the present application, the monitoring of the status of the terminal device may be monitoring of applications running in the foreground of the terminal device; correspondingly, if the applications running in the foreground of the terminal device are applications of a preset category, it means that The state of the terminal device is a first state, and the first state is a state in which the terminal device set in advance does not require high real-time performance of data transmission based on the WIFI module. For example, the application running in the foreground of the terminal device is an application that does not require network connection or an application that requires low real-time data transmission.

If the real-time requirements for data transmission are not too high, the KAT time of the WIFI module of the terminal device can be reduced, therefore, if the state of the terminal device is the first state, the WIFI module of the terminal device is adjusted The KAT time is the first time, and the first time is less than the initial time.

Of course, the first state of the terminal device may be multiple states, and different first times may be set according to different first states.

As another embodiment of the present application, before monitoring the application running in the foreground of the terminal device, the method further includes:

Monitoring the uplink data volume or the downlink data volume of the terminal device based on the WIFI module;

If the terminal device's uplink data volume or downlink data volume based on the WIFI module is greater than the data volume threshold, the application running in the foreground of the terminal device is monitored.

If the terminal device's uplink data volume based on the WIFI module is less than or equal to the data volume threshold, and the downlink data volume is less than or equal to the data volume threshold, then adjust the KAT time of the terminal device's WIFI module to For a time.

In the embodiment of the present application, the terminal device may also first monitor the uplink data amount or the downlink data amount based on the WIFI module, if the uplink data amount is less than or equal to the data amount threshold, and the downlink data amount is less than or It is equal to the data volume threshold, indicating that the terminal device currently does not have a high requirement for data transmission, and the KAT time of the WIFI module of the terminal device can be adjusted to the first time. If the amount of uplink data or the amount of downlink data is greater than the threshold of the data amount, it means that the terminal device currently has high requirements for timeliness of data transmission, and it can be further judged by the application running in the foreground of the terminal device whether the KAT of the WIFI module needs to be reduced time.

As another embodiment of the present application, if the state of the terminal device is the first state, adjusting the KAT time of the WIFI module of the terminal device to the first time includes:

If the state of the terminal device is the standby state or the screen off state, the KAT time of the WIFI module of the terminal device is adjusted to the first time.

As another embodiment of the present application, if the state of the terminal device is a standby state or a screen off state, adjusting the KAT time of the WIFI module of the terminal device to the first time includes:

If the state of the terminal device is the standby state or the screen off state, and the application running in the background of the terminal device is an application of a preset category, the KAT time of the WIFI module of the terminal device is adjusted to the first time.

In the embodiment of the present application, when the state of the terminal device is the standby state or the screen off state, it may also be used as the first state of the terminal device, or the KAT time of the WIFI module of the terminal device may be reduced.

In order to more accurately adjust the KAT time of the WIFI module of the terminal device, it may also be determined whether the application running in the background of the terminal device is an application of a preset category when the terminal device is in a standby state or a screen off state If the application running in the background of the terminal device is an application of a preset category, the KAT time of the WIFI module of the terminal device can be reduced. This is because it is possible that the terminal device also needs to download tasks through downloading software in the background when the screen is off. This situation requires relatively high timeliness of data. Therefore, if the state of the terminal device is the standby state or off In the screen state, and the application running in the background of the terminal device is an application of a preset category, the KAT time of the WIFI module of the terminal device is reduced.

Step S103: If the state of the terminal device is switched from the first state to the second state, the KAT time of the WIFI module of the terminal device is adjusted to a second time, and the second time is greater than the first time.

In the embodiment of the present application, the second state is a state other than the first state, or a specific state other than the first state. The second state is opposite to the first state, so The second state is a state in which the preset terminal device has relatively high real-time requirements for data transmission based on the WIFI module. If the second state is a state other than the first state, after the state of the terminal device is switched from the first state to the second state, the KAT time of the WIFI module of the terminal device is adjusted to the second Time, the second time may be equal to the initial time. If the second state is a specific state other than the first state, when the KAT time of the WIFI module of the terminal device is adjusted to the second time, the second time may also be greater than the initial time.

In the embodiment of the present application, after the WIFI function of the terminal device is turned on, the KAT time of the WIFI module of the terminal device is set as the initial time, and the status of the terminal device is monitored; if the status of the terminal device is first State, the KAT time of the WIFI module of the terminal device is reduced; if the state of the terminal device is switched from the first state to the second state, the KAT time of the WIFI module of the terminal device is adjusted to the initial time. In the embodiment of the present application, the KAT time of the terminal device can be adjusted in real time according to the state of the terminal device, and when the real-time requirement of the network of the terminal device is not too high for the network, the KAT time is reduced, thereby reducing the Working current, thereby reducing power consumption, when the state of the terminal device requires high real-time performance of the network, modify the KAT time to an initial value, thereby ensuring real-time performance of data transmission. In this way, it is possible to simultaneously reduce power consumption and meet user requirements for network real-time.

FIG. 2 is a schematic flowchart of another method for reducing power consumption provided by an embodiment of the present application. As shown in the figure, the method may include the following steps:

Step S201: Simulate power consumption and data transmission delay corresponding to the WIFI module of the terminal device at multiple KAT times, respectively.

In the embodiment of the present application, multiple KAT times may be selected within the selectable range of the KAT time of the WIFI module of the terminal device to simulate the corresponding power consumption and corresponding power consumption of the WIFI module of the terminal device at multiple KAT times, respectively. For data transmission delay, the selectable range of the KAT time may be set in advance, or 0 to the initial time may be used as the selectable range.

As an example, multiple times are selected as the simulation time within the selectable range of the KAT time, where the selectable range of the KAT time is [0, a], a is the initial time; the WIFI module KAT time is set as the simulation time, a preset number and a preset size of data packets are randomly transmitted in the simulation period, and the power consumption and data transmission delay corresponding to the KAT time of the WIFI module in the simulation period are counted Mean. Assume that five simulation times are selected: t1, t2, t3, t4, and t5. A simulation period may also be set, the simulation period being greater than the simulation time (for example, when the maximum simulation time is 200 ms, the simulation period may be 3 min). Set the KAT time of the WIFI module of the terminal device to the above 5 simulation times, and in each simulation period, control the terminal device to randomly transmit a preset number and a preset size of data packets to another terminal device And count the power consumption of the terminal device during the simulation period and the average transmission delay of the data packet received by another terminal device (the average delay of multiple data packets). Of course, in actual application, it is also possible to control another terminal device to randomly transmit a preset number and a preset size of data packets to the terminal device in each simulation period, and to count the terminal device during the simulation period The internal power consumption and the average transmission delay of the data packets received by the terminal device (the average delay of multiple data packets) are not limited herein. According to any one of the above-mentioned methods, the power consumption and data transmission delay (average value in any of the above-mentioned methods) corresponding to the WIFI module of the terminal device at multiple KAT times can be obtained by simulation.

Step S202, based on the respective power consumption and data transmission delay corresponding to the multiple KAT times, generate a curve of the power consumption and the data transmission delay varying with the KAT time.

In the embodiment of the present application, after obtaining the corresponding power consumption and data transmission delay when multiple KAT times are obtained, a curve of the power consumption and the data transmission delay varying with the KAT time may also be generated, In this way, the corresponding relationship between any KAT time within the selectable range of the KAT time and power consumption and data transmission delay can be obtained more accurately. The function correspondence between KAT time and power consumption and data transmission delay can be obtained according to the curve, and the function correspondence is stored in the database of the terminal device.

Step S203: After the WIFI function of the terminal device is turned on, monitor the state of the terminal device.

The content of step S203 is the same as that of step S101. For details, refer to the description of step S101, and details are not described herein again.

Step S204: If the state of the terminal device is the first state, obtain a preset maximum data transmission delay allowed by the terminal device in the first state.

In the embodiment of the present application, the maximum data transmission delay allowed by the terminal device in the first state may be preset based on the first state of the terminal device. For example, three first states are set for the terminal device in advance: Z1, Z2, and Z3, and the maximum allowed data transmission delay for the first state Z1 can be set to ty1, and the maximum allowed data transmission for the first state Z2 can be set The delay is ty2, and the maximum allowable data transmission delay for the first state Z3 is set to ty3.

Step S205: Obtain the first time corresponding to the maximum data transmission delay based on the curve, and adjust the KAT time of the WIFI module of the terminal device to the first time.

In the embodiment of the present application, in order to ensure that the terminal device can satisfy the real-time performance of data transmission while reducing the power consumption in the first state, the maximum allowable data transmission corresponding to the first state can be extended Time minus the preset delay as the data transmission delay of the terminal device in the first state, and then through a pre-simulated curve (curve of the data transmission delay varying with the KAT time) or a functional relationship ( The corresponding relationship between the KAT time and the data transmission delay function) obtains the time corresponding to the current data transmission delay in the first state as the first time.

As an example, assume that the state of the terminal device is the first state Z3, and the maximum allowable data transmission delay set in the first state Z3 is ty3. In order to ensure the timeliness of data transmission, ty3 may be subtracted from y3 as the The data transmission delay of the terminal device in the first state Z3, and then, a KAT time corresponding to (ty3-y3) is obtained based on the curve, and this KAT time is the first time. If the corresponding time is not obtained according to (ty3-y3), but the corresponding time is obtained according to ty3, it is likely to be caused by other factors (such as the error of the analog curve or function, the error of setting the maximum allowable data transmission delay) After the KAT time of the WIFI module of the terminal device is set to the first time, although the reduction in power consumption is guaranteed, it may not meet the real-time requirements of data transmission. Therefore, the preset delay y3 is set to ensure that the KAT time of the WIFI module is set to the first time, and the real-time performance of data transmission can also be satisfied.

It should be noted that, in the embodiment shown in FIG. 2, the obtained curve may not include the curve of the power consumption changing with the KAT time, or may include the curve of the power consumption changing with the KAT time. The obtained functional relationship may not include the functional relationship between the power consumption and the KAT time, or may include the functional relationship between the power consumption and the KAT time.

FIG. 3 is a schematic diagram of an implementation process of another method for reducing power consumption provided by an embodiment of the present application. As shown in the figure, the method may include the following steps:

Step S301: Simulate the power consumption and data transmission delay corresponding to the WIFI module of the terminal device at multiple KAT times, respectively.

This step is consistent with the content of step S201. For details, reference may be made to the description of step S201, and details are not described herein again.

In the embodiment of the present application, the first time corresponding to the first state of the terminal device may also be obtained through other methods. For example, to display a preset interface and receive the first time corresponding to the first state set by the user through the preset interface, refer to step S302.

Step S302, displaying power consumption and data transmission delay corresponding to multiple KAT times in the preset interface respectively, and receiving a KAT time selected by the user based on the power consumption and data transmission delay corresponding to the multiple KAT times respectively As the first time corresponding to the first state.

In the embodiment of the present application, when there are multiple first states, the user may set a first time for each first state separately, for example, by displaying a preset interface, the preset interface may display the terminal device In the first state, the power consumption and data transmission delay respectively corresponding to the terminal device when multiple KAT times obtained through pre-simulation can also be displayed. The user can select one of the multiple KAT times according to the power consumption and data transmission delay of the terminal device corresponding to the displayed multiple KAT times as the currently displayed first state to be set corresponding to the preset interface. first timing. It is also possible to input a time as the first time corresponding to the first state to be set currently displayed on the preset interface according to the power consumption and data transmission delay respectively corresponding to the terminal device when displaying multiple KAT times.

As an example, when the first state is that the application running in the foreground of the terminal device is an application of a preset category, the user may set the first time corresponding to the first state to ta before running the application a, while running the application Before b, the first time corresponding to the first state is set to tb.

Of course, the initial time of the WIFI module may also be displayed in the preset interface to remind the user that the first time set corresponding to the first state is less than the initial time.

Through step S301 and step S302, the user can set the first time of the first state according to personal habits, and can also modify the first time of the first state at any time. According to the above method, when the state of the terminal device is the first state, the KAT time of the WIFI module of the terminal device can be adjusted to the first time. Of course, after the historical period has passed, the first time corresponding to the first state of the terminal device may also be obtained in other ways.

Step S303: Obtain the first time corresponding to the first state set by the user through the preset interface in the historical period.

In the embodiment of the present application, the user can set or modify the first time corresponding to the first state at any time, and can also set a historical period, for example, one week, half month, and one month. After the elapsed time period, the first time corresponding to the first state set by the user through the preset interface during the historical period may be obtained.

Step S304: Train a pre-built convolutional neural network model based on the first time corresponding to the first state to obtain a trained convolutional neural network model.

In the embodiment of the present application, the characteristic parameter of the first state may be obtained, and the characteristic parameter of the first state includes at least one of the following: the terminal device is based on the uplink data amount of the WIFI module, and the terminal device is based on The amount of downlink data of the WIFI module, the category of applications running in the foreground of the terminal device, the category of applications running in the background of the terminal device, whether the terminal device is in a sleep state or a screen-off state, and the current time. The feature parameters of the first state are used as the input of the pre-built convolutional neural network model, and the first time corresponding to the first state is used as the label value to train the convolutional neural network model to obtain the trained Convolutional neural network model. Loading the trained convolutional neural network model into the terminal device. It is also possible to obtain the first time corresponding to the first state set by the user through the preset interface in the current historical period every time a historical period passes, and then train the training center based on the first time corresponding to the first state The convolutional neural network model currently loaded in the terminal device is obtained to obtain the convolutional neural network model corresponding to this historical period. In this way, the convolutional neural network model loaded in the terminal device is a mathematical model conforming to the user's personal behavior habits.

Step S305: After the WIFI function of the terminal device is turned on, monitor the state of the terminal device.

Step S306, if the state of the terminal device is the first state, acquire the characteristic parameters of the first state, and input the characteristic parameters of the first state into the trained convolutional neural network model to output the first time, And adjust the KAT time of the WIFI module of the terminal device as the first time output.

In the embodiment of the present application, the first state may be a plurality of preset states. Although the first state is set, actually, the terminal device may have different characteristic parameters in the first state, and the The convolutional neural network model is trained based on the feature parameters. Therefore, at the first time when the output is obtained through the convolutional neural network model, the feature parameters of the first state can be obtained and the The feature parameters are input to the trained convolutional neural network model to output the first time, and the KAT time of the WIFI module of the terminal device is adjusted to the first time output. The first time obtained through the convolutional neural network model can be more in line with the user's personal behavior habits. It is an adaptive way to adjust the KAT time to reduce the power consumption while meeting the timeliness of data transmission.

It should be noted that the priority of the first time set by the user through the preset interface is higher than the first time output by the convolutional neural network model. After the user sets the first time in the first state through the preset interface, the KAT time is adjusted according to the first time set by the user through the preset interface. A virtual button can be set on the terminal device, and the user can switch to adjust the KAT time according to the first time output by the convolutional neural network model through the virtual button.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
