For example, the terminal further includes a network interface connected through a system bus, and the network interface may be an Ethernet card or a wireless network card, etc., for communicating with an external terminal, for example, for communicating with a server.

In one embodiment, as shown in FIG. 2, a partial architectural diagram of a terminal is provided. The architecture system of the terminal includes a JAVA spatial layer 210, a local framework layer 220, and a kernel (Kernel) spatial layer 230. The freeze and thaw application 210 can be included in the JAVA spatial layer. The freeze and thaw application 210 can be used by the terminal to implement a freeze policy for each application, and freeze the related application of the background power consumption. The resource priority and restriction management module 222 and the platform freeze management module 224 are included in the local framework layer 220. The terminal can maintain different applications in different priorities and different resource organizations through the resource priority and limit management module 222, and adjust the resource group of the application according to the requirements of the upper layer to achieve optimized performance and save power. . The terminal freezes the task that can be frozen in the background by the platform freeze management module 224, and allocates the freeze layer to the preset different levels according to the length of the entry freeze time. Optionally, the freeze layer may include three, respectively: CPU limit Sleep mode, CPU freeze sleep mode, process deep freeze mode. The CPU restricts the sleep mode to limit the CPU resources occupied by the related processes, so that the related processes occupy less CPU resources, and the free CPU resources are tilted to other unfrozen processes, thereby limiting the occupation of CPU resources. It also limits the occupation of network resources and I/O interface resources; CPU freeze sleep mode refers to prohibiting related processes from using CPU, while preserving the occupation of memory, when prohibiting the use of CPU resources, the corresponding network resources and I The /O interface resource is also forbidden; the process deep freeze mode means that in addition to prohibiting the use of CPU resources, the memory resources occupied by the related processes are further recovered, and the recovered memory can be used by other processes.

The process memory recovery module 234 is configured to implement the process deep freeze mode, so that when a third-party application is in a frozen state for a long time, the file area of the process is mainly released, thereby saving the memory module and speeding up the application next time. The speed at startup. The timeout freeze exit module 235 is configured to solve the abnormality generated by the freeze timeout scenario. Through the above architecture, the application freezing method in various embodiments of the present application can be implemented.

In one embodiment, as shown in FIG. 3, an application freezing method is provided for freezing a foreground application of a terminal. This embodiment is described by applying the method to the terminal shown in FIG. 1 as an example. The application freezing method includes steps 302-306. among them,

Step 302: When the current station starts the application, the foreground application currently running is monitored to receive operation information input by the user; the operation information includes an operation mode and an operation time point.

The operation of an application (APP) is usually reflected by the operation of multiple related processes. The process involved in the foreground application runtime is the foreground process, and the process involved in the background application runtime is the background process. The application corresponding to the operation page of the application displayed by the current display interface of the terminal is the foreground application currently running by the terminal. In this embodiment, only the application corresponding to the input focus is the foreground application, or only the application corresponding to the window object at the top of the stack of the window stack of the operating system is the foreground application currently corresponding to the terminal. To determine whether the target application is a foreground application, obtain a window object corresponding to the target application, and determine whether the window object is located at the top of the stack of the window stack of the operating system, and if yes, the target application is a foreground application, and if not, the description is The app runs in the background and is a background app.

When the foreground application is opened, the foreground application will listen to the operation information input by the user. It should be noted that the operation information includes an operation mode and an operation time point input by the user. The operation mode includes at least an input operation mode such as a button, a voice, a touch, a fingerprint, and a scan. At the same time, when the operation information input by the user is received, the current input operation time point is also obtained. For example, when the application opened by the current station is “Glory of the King”, it monitors all input information of the user, such as voice, touch, and the like, when the user uses the foreground application, and also records the current operation. The input time point corresponding to the input mode, such as voice input - 20:00: 00; touch input - 20:00: 01 and so on.

Step 304: Invoke each application to receive a mapping relationship between the operation mode input by the user and the freeze condition, and determine, according to the operation information, whether the foreground application needs to be frozen at the current time.

When the application is running in the foreground, the application can be considered as a foreground application, and each foreground application running in the foreground corresponds to one or more freeze conditions, and the corresponding freeze condition can be determined according to the operation mode of receiving the user input. The operation mode corresponds to a freeze condition. For example, the freeze condition corresponding to the touch operation mode is the first freeze condition, the freeze condition corresponding to the voice operation mode is the second freeze condition, and the freeze condition corresponding to the scan operation mode is The third freezing condition and so on. That is, each operation mode of each application can correspond to a freeze condition.

Further, the freezing condition is a time condition, and a time freezing condition corresponding to each operation mode may be set, and the time freezing condition may be understood to be that when a certain operation information is not monitored within the preset time period, the time freezing condition is considered to be satisfied. .

It should be noted that the operation mode of each application is different, and the freezing conditions corresponding to the same operation mode of different applications may be the same or different.

According to the preset mapping relationship, according to the operation information of the monitoring, it can be determined whether the current application needs to freeze the foreground application.

Step 306: When the foreground application needs to be frozen, the foreground application is frozen according to a preset policy.

When the foreground application needs to be frozen, the foreground application is frozen according to the preset policy. For example, the corresponding freeze policy may be set according to the monitored operation information to implement the freeze operation on the foreground application. For example, different freeze levels may be set according to the acquired operation information, and the freeze of the foreground application may be implemented according to the freeze level.

In the above frozen application method, when the current application is started, the foreground application currently being monitored receives the operation information input by the user, and according to the operation information and the preset mapping relationship, it can be determined whether the foreground application needs to be frozen at the current time; When the application is applied, the foreground application is frozen according to the preset policy, and the operation information input by the user is received according to the foreground application to decide whether to freeze the foreground application, that is, the operation information can be used to obtain the usage rate of the current user to the foreground application. When the user does not input the operation information for a long time, the user can freeze the foreground application in time to improve the intelligence of the terminal.

In an embodiment, as shown in FIG. 4, before mapping the relationship between the received operation mode and the freeze condition of each application, the mapping relationship needs to be constructed.

Before invoking each application to receive a mapping relationship between the operation mode input by the user and the freeze condition, step 402-step 406 is included. among them,

Step 402: Acquire a historical running time of each running of the application in the foreground and receive a historical operation record input by the user.

The terminal obtains the operation information input by the user when each application runs in the foreground, and counts the historical running time of each application running in the foreground and the historical operation record input by the user. The historical running time is a continuous running time of the foreground application; the historical operation record includes a historical operation mode, and a usage frequency corresponding to the operation mode. The historical operation mode includes at least a operation mode such as a button, a voice, a touch, a fingerprint, and a scan, and the usage frequency corresponding to the operation mode is the frequency of use of each operation mode.

When the current running "God Glory" game application (APP), the terminal will record the start time point of turning on or switching from the background to the foreground running "Glory Glory", and ending or switching to the background end time point, The duration between the start time and the end time is the historical run time, such as 40 minutes. During the historical running time, the input operation mode of the receiving user includes voice input and touch input. According to the input operation mode, the frequency of use of each operation mode can be obtained, wherein the frequency of use of the touch operation mode is 120 times/minute, and the voice operation is 2 times/minute.

When the current application (APP) of the player such as "OPPO Video Player" is running, the terminal records the startup time point of turning on or switching from the background to the foreground to run the "OPPO Video Player", and ending or switching to the end of the background. At the time point, the duration between the start time point and the end time point is the historical running time, such as 120 minutes. During the historical running time, the input operation mode of the receiving user includes a touch input, a sliding input, and the like. According to the input operation mode, the frequency of use of each operation mode can be obtained, wherein the frequency of the touch input operation mode is 2 times/60 minutes, and the sliding input operation mode is 6 times/60 minutes.

Step 404: Set a freeze condition of each foreground application according to the historical running time length and the usage frequency corresponding to the operation mode. Wherein, the freezing condition is a time condition.

The running time of each application running in the foreground is different, and the operation mode of receiving user input may also be different. The corresponding freezing condition can be set for each application. For example, if the game application APP "King of the Glory" running in the foreground, the freezing condition can be divided according to the received operation mode, when the king glory is in the foreground application, if the touch operation is not monitored within the first preset duration And satisfying the first freezing condition; wherein the first preset duration is related to the frequency of use in the historical operation record, when the first preset duration is greater than a preset multiple of the usage frequency of the touch operation mode (120 times/minute) Then, it can be determined that the touch operation mode is not generated again within the first preset time period, and it can be determined that the user is not currently using the currently running foreground application.

When the king glory is in the foreground application, if the voice operation is not monitored within the second preset time period, the second freeze condition or the like is satisfied. The second preset duration is related to the frequency of use in the historical operation record. When the second preset duration is greater than the preset multiple of the voice operation mode (2 times/1 minute), it may be determined that the second During the preset duration, the voice operation mode will not be generated again, indicating that the user is not currently using the currently running foreground application.

It should be noted that the first preset duration and the second preset duration may be set according to user requirements, and no further limitation is made.

Step 406: Construct a mapping relationship between the operation mode and the freeze condition of each foreground application.

The freeze condition of each foreground application is set according to the historical running time and the usage frequency corresponding to the operation mode. Each application has one or more operation modes, and each operation mode corresponds to a freeze condition, that is, one application can correspond to multiple freeze conditions. A mapping relationship in which such an application may correspond to a plurality of freeze conditions is graphically represented for identification purposes.

Further, the operation mode of the user input that each foreground application can monitor is diverse, and the freezing condition of the application can be set according to the input mode most commonly used by the user, and the freezing condition corresponding to other operation modes is ignored.

In addition, the priority of the freeze condition may be set according to the frequency of use of the operation mode, and the user's use frequency is higher, and the corresponding freeze condition is used as a priority condition for freezing the application. That is, the freeze of the foreground application may be judged according to the priority of the freeze condition corresponding to the operation mode.

In an embodiment, as shown in FIG. 5, the determining, according to the mapping relationship, whether the current time needs to freeze the foreground application, includes steps 502-506. among them,

Step 502: Acquire the operation information that is closest to the current time, and record the time interval of the latest operation information from the current time.

When the foreground application is enabled, the foreground application monitors the operation information input by the user, and the operation mode includes at least an input operation mode such as a button, a voice, a touch, a fingerprint, and a scan. At the same time, when the operation information input by the user is received, the current input operation time point is also obtained.

The latest operation information may be the operation information corresponding to the operation time point of the shortest time interval between the current time and the operation information input by the foreground application from the start of the current application.

If the current time is 20:30:00 in the evening, the front desk of the terminal is running "Glory of the King", the user will operate the game during the process of using the "Glory of the King", and the terminal will monitor the operation information input by the user in real time. . At the current time (20:30:00), the terminal will obtain the operation information (operation mode and operation time point) that was last monitored from the current time (20:30:00). If the latest operation information is used, the operation mode For the touch operation mode, the operation time point is 20:20:00, and the time interval from the current time can be obtained, and the time interval is 10 minutes.

Step 504: Determine, according to the mapping relationship, whether the time interval satisfies the freezing condition.

The set mapping relationship is invoked to obtain the freezing condition corresponding to all the operation modes of the application. As described above, the freezing condition is a time condition, and according to the mapping relationship, it can be known whether the acquired time interval satisfies the freezing condition of freezing the foreground application.

Step 506: When the freezing condition is met, the terminal detects whether there is a face image in the visible area.

According to the set mapping relationship, when the time interval satisfies the freezing condition, it can be determined that the user does not operate the foreground application, and the terminal can detect whether the current terminal's visible area is a face image, and the current terminal can be determined. Whether there is a user before. The visible area can be understood as the area where the user can normally use the terminal, and can also be understood as the distance between the user and the terminal, which is the comfortable distance of the user using the terminal.

Specifically, the face recognition technology can be used to detect whether a person exists before the terminal. Face recognition is a biometric recognition technology based on human facial feature information for identification. Using a camera or camera (front camera) to capture an image or video stream containing a face image, and automatically detect and track the face image in the image, and then perform a series of related techniques on the face of the detected face image, usually Also known as portrait recognition, face recognition. Through the terminal processing, if the face image is recognized, it indicates that the user is viewing the display area of the terminal, but the user does not operate the terminal; if there is no face image, it indicates that the current user has been away from the terminal, and the user needs to freeze the Front desk application. That is, step 508: when the face image does not exist, the foreground application needs to be frozen.

When there is no face image, it indicates that the current user is far away from the terminal, and the currently running foreground application can be frozen to save power.

Further, in an embodiment, as shown in FIG. 6, it is determined whether the foreground application needs to be frozen according to the category information of the foreground application, and further includes steps 602-606. among them,

Step 602: When the face image is present, the age feature of the current face image is obtained by the face recognition technology.

When there is a face image, it indicates that the user is viewing the display area of the terminal, but the user does not operate the terminal, and the age of the face image can be identified based on the method of constructing the face recognition and age synthesis joint model of deep learning. feature. By aligning and unsupervised/supervised the face image collected by the camera, the preprocessing of the dimensionality reduction is performed, and through a trained automatic encoder, the feature set for the identity representation and the feature set represented by different age groups are obtained, and then The results of the feature set are outputted by the parallel convolutional neural network, and the image similarity is output. Then the weighted fusion is used to obtain the matching result, which can realize face recognition and age detection to obtain the age feature of the face image. Because it distinguishes the characteristics of age characteristics and face image identity, it is also robust to face recognition across ages.

Step 604: Acquire application information of the foreground application.

Obtain application information applied by the foreground, where the application information includes an application network identifier and an application type. The application network identifier includes a mobile cellular network identifier and a wireless network identifier. The application type can be divided into puzzle, game, audio and video, instant communication, system tools, etc. according to the function division of each application; according to whether the application needs to use network division, it can be divided into networked and non-networked, among which Networking applications include communication applications, mailboxes, browsers, dialers, and SMS services.

Step 606: Determine, according to the application information, whether the foreground application needs to be frozen according to the corresponding relationship between the age feature and the exclusive application.

According to the age feature, the user can be divided into multiple user groups, such as an elderly user group, a middle-aged user group, a youth user group, and a child user group. Among them, the exclusive application can be separately formulated for the elderly user group and the child user group.

For the elderly user group, the corresponding exclusive application is an application that can be run under the WIFI connection state. According to the application information of the foreground application, it can be determined whether the foreground application is a dedicated application corresponding to the old user group (an application that can be run under the WIFI connection state), and if not, an application that needs to be operated by the mobile cellular network is considered to be The foreground application needs to be frozen to prevent large amounts of data traffic due to misuse.

For the children's user group, the corresponding exclusive application is a puzzle application. According to the application information of the foreground application, it can be determined whether the foreground application is a dedicated application corresponding to the child user group (educational application), and if not, but for games and audio-visual applications other than the puzzle application, The foreground application needs to be frozen, reducing the probability that student users are addicted to the game.

In an embodiment, as shown in FIG. 7, the foreground application is frozen according to a preset policy, including steps 702-706. Step 702: Obtain a duration of the time interval when the time interval satisfies the freezing condition.

Obtain the operation information closest to the current time, and record the time interval of the latest operation information from the current time. The latest operation information is the operation information corresponding to the operation time point of the shortest time interval between the current time and the operation information input by the foreground application from the start of the current application. When the acquired time interval satisfies the freeze condition, the duration of the time interval is obtained.

Step 704: Divide a freeze level according to the duration; the freeze level is used to indicate that the maximum allowed resource that can be used by the foreground application is configured.

The freeze level is divided according to the duration of the acquired time interval. The freeze level is used to indicate the maximum allowed resources that can be used by the foreground application. Among them, the resources that can be used represent the resources that the process can use at each moment of execution. The maximum allowed resource represents the maximum resource that the process is allowed to use at various times. The longer the interval, the higher the freeze level, and the higher the freeze level, the less the maximum allowed resources for the foreground application.

There are multiple running processes in the terminal. The process is a basic operation of a program on a certain data set in a computer. It is the basic unit for resource allocation and scheduling, and is the basis of the operating system structure. The process involved in the foreground application runtime is the foreground process, and the process involved in the background application runtime is the background process.

In the operating system, the interaction mechanism between processes is mainly divided into a synchronization mechanism and a communication mechanism. Among them, the communication mechanism includes socket, binder, shared memory and so on. The two programs on the network exchange data through a two-way communication connection. One end of the connection is called a socket. Binder is an interprocess communication mechanism that provides remote procedure call functionality.

The terminal may acquire the foreground process according to a preset frequency or according to the detected user operation instruction. Optionally, the process identifier of the foreground process may be obtained, where the process identifier is used to uniquely identify the corresponding process, and may be formed by a combination of one or more of a preset number of digits, letters, or other characters. For example, the process ID "0001" may be used to indicate the process A, and the "1234" may be the process B or the like.

It should be noted that the manner of dividing the freeze level may be set according to the needs of the user, and may be set in combination with the historical running time of the foreground application and the application type of the foreground application. The division rules of the freeze level of each application may be the same or different, and the number of division levels may be the same or different.

Step 706: Perform freeze on the foreground application according to the freeze level.

The freeze level corresponding to the current time interval is determined according to the duration of the time interval. If the memory required for the current process execution is 40Mb, if the freeze level is one level (lowest level), the resource is allocated to the foreground according to the level 1 freeze level, and the maximum allowable resource that the foreground application can use is 30Mb; The level is level 4 (the highest level), the resources are allocated to the foreground according to the level 1 freeze level, and the maximum allowable resource that the foreground application can use is 0Mb. Among them, the highest level of freezing level is completely frozen.

The foregoing resources may include a CPU, an I/O file resource, and the like. Taking resources as memory for example, the longer the interval, the higher the freeze level; the higher the freeze level, the less the maximum allowed resources that the foreground application can use.

In the above method, the freeze level is set according to the duration of the time interval, and as the time length increases, the freeze level also increases, but the maximum allowable resource that can be used by the foreground application decreases, until the foreground application is applied. It is completely frozen. From partial freezing to complete freezing, it takes a certain time process to give the user a buffering time period. During this time period, the user can quickly and effectively unfreeze the foreground application and improve the user experience. At the same time, according to the freeze level, the maximum allowable resources that can be used by the foreground application can be restricted, and resources can be allocated reasonably to reduce power consumption.

In an embodiment, as shown in FIG. 8, the foreground application is frozen according to a preset policy, including steps 802-806. Step 802: Acquire all the functions of the foreground application and the functions corresponding to the operation mode currently monitored by the foreground application.

The functions of the foreground application are various. When the freeze condition is met, the function corresponding to the operation mode monitored by the foreground application is obtained. One mode of operation may correspond to one or more functions. For example, voice operations may correspond to functions such as voice communication, voice control, voice search, etc. Scan operations may correspond to functions such as scan recognition, scan payment, scan authentication, and the like. By obtaining the operation mode of the monitoring, the function corresponding to the monitored operation mode can be obtained.

It should be noted that the functions corresponding to the operation mode may include, but are not limited to, recording, photographing, connecting to the network, using Bluetooth, acquiring a geographical location, making a call, and sending a short message.

Step 804: Acquire an unused function according to a function corresponding to the monitored operation mode.

When users use the current foreground application, there are generally functions that users do not use often. Unused functions refer to all functions of the foreground application, except for the functions corresponding to the monitored operation mode.

Take the "King of Glory" game application of the terminal as an example. The "Glory of the King" includes many functions, such as the competitive function corresponding to the touch operation, the transaction function, the location acquisition function, the voice instant communication function corresponding to the voice operation, and the recording Features and more. When the time interval satisfies the freeze condition, the functions corresponding to the acquired operation mode monitored by the foreground application are mainly the competitive function and the voice instant communication function, and the unused functions include the transaction function, the geographic location acquisition function, the recording and photographing function, and the like. Wait.

Step 806: Freeze the corresponding process of the unused function in the system.

Each application corresponds to a process group in the system framework. When the application is running, the system allocates resources to its corresponding process group; and each functional module in the application also corresponds to the process in the process group, so each application will be applied. The corresponding process of the function is identified to facilitate subsequent management of system resource allocation to the corresponding process. The identifier is used to uniquely identify the corresponding process, and may be composed of a combination of one or more of a preset number of digits, letters, or other characters. For example, process ID "0001" can be used to represent process A, and "1234" can be used to indicate process B, etc.

Take the terminal's "King of Glory" game application as an example. When the current station runs "King of Glory", it can obtain unused functions according to the function corresponding to the monitored operation mode. Among them, unused functions (transaction function, location acquisition function, recording camera function, etc.). However, unused features also run in the background, taking up system resources.

Through the above method, the user can freeze the unused functions in the corresponding processes in the system, thereby achieving the purpose of saving resources and improving operational efficiency. However, other functions of the foreground application can still be used, so the application does not need to freeze the entire application, but freezes some functions of the application, and ensures that other functions are used normally, thereby achieving the effect of reducing power consumption.

In one embodiment, as shown in FIG. 9, the application freeze method further includes steps 902- 906. among them,

Step 902: Acquire a thaw instruction for thawing the foreground application.

Step 904: Detect whether biometric information in the thaw instruction matches a preset biometric.

Step 906: Perform a thawing operation on the foreground application when the biometric information in the defrosting instruction matches the preset biometric.

That is, after the current application is frozen, when the foreground application needs to be thawed, it is necessary to obtain the thaw instruction input by the user. The defrosting command includes biometric information, wherein the biometric information may be fingerprint information, iris information, voiceprint information, facial information, and the like.

It should be noted that different applications can set different biometric information, and can also set the same biometric information, and can be customized according to the needs of the user.

When the biometric information in the thaw instruction matches the preset biometric information, the foreground application is thawed. During the defrosting operation, the corresponding defrosting strategy can also be set according to the freezing strategy to implement the defrosting operation of the foreground application.

It should be understood that although the various steps in the flowcharts of FIGS. 3-9 are sequentially displayed as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Except as explicitly stated herein, the execution of these steps is not strictly limited, and the steps may be performed in other orders.
