The priority of the Chinese patent application titled "A method and equipment for resource management and control", the entire content of which is incorporated into this application by reference.

Technical field

The embodiments of the present application relate to the field of electronic technology, and in particular to a method and equipment for resource management and control.

Background technique

At present, electronic devices such as mobile phones or tablet computers usually support background multitasking, and applications can continue to run after switching from the foreground to the background. For example, an instant messaging application can receive messages in the background, a navigation application can continue to navigate in the background, and a music application can play songs in the background. Background applications need to use resources while they are running.

In the prior art, the resources involved in the application program are managed and controlled according to the package name of the application program package (package) or the user identity (UID) of the application program. This control method includes allowing the use of resources or restricting the use of resources. In order to enable the application program to continue to run in the background, the prior art allows the background application program to use resources normally.

In this solution, when the application program is running in the background, especially when there are multiple application programs running in the background, the background application program will cause the resource consumption and power consumption of the electronic device to be relatively large.

Summary of the invention

The embodiments of the present application provide a resource management and control method and device, which can perform fine-grained management and control of resource usage according to processes in a background application, and can perform different levels of resource management and control for different processes, thereby reducing the burden of background applications. Resource consumption, reduce the power consumption of electronic equipment.

To achieve the foregoing objectives, the following technical solutions are adopted in the embodiments of the present application:

On the one hand, an embodiment of the present application provides a resource management and control method, including: an electronic device displays an interface of a first application program. The electronic device switches from running the first application program in the foreground to running the first application program in the background, and stops displaying the interface of the first application program. The electronic device determines the critical process and the non-critical process in the first application program. The electronic equipment adopts the first management and control method and the second management and control method respectively to process the resources of the critical process and the non-critical process. Among them, the second management and control method has a greater degree of resource management and control than the first management and control method.

In this solution, the mobile phone can perform fine-grained management and control of resource usage according to the process of the background application, and can perform different levels of resource management and control for the key and non-critical processes of the background application. Thus, the resource consumption of each application program in the background can be reduced, and the power consumption of the electronic device can be reduced.

In a possible design, the electronic device determines the critical process and the non-critical process in the first application program, including: if the first process in the first application program is in the process whitelist, the electronic device determines that the first process is The key process. If the first process in the first application is in the process blacklist, the electronic device determines that the first process is a non-critical process.

In other words, the electronic device can determine the critical process and the non-critical process according to the preset whitelist and blacklist.

In another possible design, the electronic device can determine the critical process and the non-critical process according to the priority of the process in the first application.

For example, determining the critical process and non-critical process in the first application by the electronic device includes: if the ADJ value of the first process in the first application is less than or equal to FORREGROUND_APP_ADJ, the electronic device determines that the first process is a critical process. If the ADJ value of the first process in the first application is greater than FORREGROUND_APP_ADJ, the electronic device determines that the first process is a non-critical process.

That is to say, the electronic device can determine the critical process and the non-critical process through information that characterizes the priority of the process, such as the ADJ value.

In another possible design, the electronic device determines the critical process and the non-critical process in the first application, including: if the first process in the first application is located in the SCHED_GROUP_BACKGROUND group, the electronic device determines that the first process is The key process. If the first process in the first application is located in another group, the electronic device determines that the first process is a non-critical process.

In other words, the electronic device can determine the critical process and the non-critical process through the grouping of the process.

In another possible design, the electronic device determines the critical process and the non-critical process in the first application program, including: if the first process in the first application program uses the foreground service, the electronic device determines that the first process is The key process. If the first process in the first application does not use the foreground service, the electronic device determines that the first process is a non-critical process.

In this way, the electronic device can determine whether it is a critical process according to whether the process in the background application uses the foreground service.

In another possible design, the electronic device determines the critical process and the non-critical process in the first application program, including: if the first process in the first application program meets the target characteristics, the electronic device determines that the first process is critical Process; where the target feature is a preset feature, or a feature obtained through training of an electronic device. If the first process in the first application program does not meet the target characteristics, the electronic device determines that the first process is a non-critical process.

In this solution, the electronic device can determine whether it is a critical process according to the characteristics of the process in the background application.

In another possible design, the electronic device adopts the first management and control method and the second management and control method to process the resources of the key process and the non-critical process, including: the electronic device switches to the background operation in the first application program and experiences After the preset time period T, the electronic device adopts the first management and control mode and the second management and control mode respectively to process the resources of the critical process and the non-critical process.

It is understandable that when the first application program is just switched to the background, the user is more likely to use the first application program in the foreground again, so the electronic device may temporarily not perform resource management and control on the background first application program. After the first application program is switched to run in the background and the preset time period T has elapsed, the probability of the user using the first application program in the foreground again is small, and the electronic device can perform resource management and control on the background first application program.

In another possible design, before the electronic device adopts the first management and control mode and the second management and control mode to process the resources of the critical process and the non-critical process, the method further includes: the electronic device is the first application program Process to apply for resources. The electronic device stores resource application information, and the resource application information includes the corresponding relationship between the process and the requested resource. Electronic equipment adopts the first management and control method and the second management and control method to process the resources of the key process and the non-critical process, including: the electronic equipment adopts the first and second management methods according to the resource application information, respectively, and controls the key process and the second control method. Non-critical processes handle resource processing.

That is to say, the electronic device can record the corresponding relationship between the process and the resource when the process applies for the resource, so as to subsequently perform resource management and control on the process according to the corresponding relationship.

In another possible design, the first control method includes unifying key processes based on the heartbeat packet of the timing alarm Alarm, allowing key processes to use other resources.

In this way, the normal operation of key processes can be guaranteed, and the resources and power consumption consumed by the heartbeat packet can be reduced.

In another possible design, the second control method includes restricting the use of resources by non-critical processes.

In this way, the resource consumption and power consumption of the first application in the background can be more saved.

In another possible design, the key processes include the first level, the second level, and the third level. Among them, the first management and control method corresponding to the first-level key process includes allowing the key process to use resources. The first management and control method corresponding to the second-level key processes includes the first cycle of unifying key processes based on the heartbeat packet of the timing alarm Alarm, allowing key processes to use other resources. The first management and control method corresponding to the third-level key processes includes unifying the key processes in the second cycle based on the heartbeat packet of the timing alarm Alarm, allowing the key processes to use other resources, and the second cycle is greater than the first cycle.

In this way, the degree of resource management performed by different levels of key is different, and the resource consumption and power consumption are also different.

In another possible design, non-critical processes include the first level and the second level. Among them, the second management and control method corresponding to the non-critical processes of the first level includes periodically restricting the use of resources by the non-critical processes. The second control method corresponding to the second-level non-critical processes includes restricting the use of resources by non-critical processes.

In this way, different levels of non-critical resource management and control have different degrees, and resource consumption and power consumption are also different.

In another possible design, the first control method includes allowing the use of critical resources and restricting the use of non-critical resources.

In this way, through the normal use of key resources, it is possible to make the functions and services of key processes run normally while minimizing resource consumption and power consumption.

If the first process in the first application is in the process blacklist, it is determined that the first process is a non-critical process.

In another possible design, determining the critical process and the non-critical process in the first application program includes: if the ADJ value of the first process in the first application program is less than or equal to FORegROUND_APP_ADJ, then determining that the first process is critical process.

detailed description

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Among them, in the description of the embodiments of the present application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in this document is only a description of related objects The association relationship of indicates that there can be three kinds of relationships, for example, A and/or B, which can indicate: A alone exists, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "plurality" refers to two or more than two.

Hereinafter, the terms “first” and “second” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present embodiment, unless otherwise specified, "plurality" means two or more.

The application can be identified by the package name of the application or the UID of the application user identity. Among them, each UID can correspond to one or more applications. The application can create multiple processes during the running process, and each process can apply for the use of resources according to its own business needs.

For example, in a resource division method, the resources applied for by the process of the application program may include hardware resources and software resources. For example, the hardware resources may include global navigation satellite system (GNSS) resources, network resources, bluetooth (BT) resources, transmission control protocol TCP connection resources, audio resources or modem resources, etc. Among them, GNSS resources can include global positioning system (GPS) resources, global navigation satellite system (GLONASS) resources, Beidou navigation satellite system (BDS) resources, and quasi-zenith Satellite system (quasi-zenith satellite system, QZSS) resources and/or satellite-based augmentation systems (satellite-based augmentation systems, SBAS) resources, etc. Network resources refer to resources that can be used for surfing the Internet, such as operators' mobile data service (2G/3G/4G/5G) resources or wireless fidelity (Wi-Fi) resources. The TCP connection can exchange information through the socket Socket link. Audio resources are used to implement audio playback, such as speaker resources or audio codec resources.

Taking the Android operating system as an example, the software resources may include timing alarm resources, wakelock resources, broadcast resources, delayed processing job resources or service service resources, etc. Among them, the Alarm resource can be used for system-level prompts according to the set time or cycle. Wakelock resources can be used to prevent the processor from sleeping. Broadcast resources can be used to transfer information between different applications or different components. Job resource is a resource in a library that can be processed in a delayed manner in the background. Service resource is an application component that can perform long-running operations in the background without a user interface.

Exemplarily, a schematic diagram of a process in an application program applying for resources can be seen in FIG. 1A. During the process of applying for resources in the application program, the resource manager in the electronic device running the application program may save the resource application information. For example, in the prior art, referring to FIG. 1B, the resource application information includes the package name and UID of the application requesting the resource, and the resource requesting the application. In addition, the resource application information may also include relevant information such as the application time and application duration of the resource. In other words, the prior art counts the resource application information of the process according to the package name and UID.

In the prior art, the electronic device performs resource management and control according to the package name or UID of the application program. In order to enable the application program to run in the background, the electronic device allows the application program to enter the background to be able to use various resources normally.

For example, the package name of background application 1 is package name 1, and the corresponding UID is UID1. In a prior art, the electronic device allows the requested resource corresponding to package name 1 to be used normally; in another prior art, the electronic device allows the requested resource corresponding to UID1 to be used normally, so that the application Program 1 can run in the background.

Since the background application program can include multiple processes, the existing technology allows each process in the background application program to use resources normally, but in fact the resources of some processes do not necessarily need to be used, so the existing technology adopts the solution As a result, the resource consumption and power consumption of the electronic device are relatively high.

The embodiment of the present application provides a resource management and control method, which can be applied to electronic devices. Electronic devices can perform fine-grained management and control of resource usage based on processes in background applications. In addition, for different processes in the background application, the electronic device can perform different levels of resource management and control. Among them, the electronic device can control the resources of some processes in the background application regardless of control or weak control, that is, the degree and intensity of control is small; and the resources of other processes can be strongly controlled, that is, the degree and intensity of control is greater. Therefore, compared with the prior art allowing each process in the background application program to use various resources normally, the resource management and control method provided by the embodiment of the present application can reduce the resource consumption of each background application program and reduce the power consumption of the electronic device.

For example, the electronic device may be a mobile phone, a tablet computer, a folding screen device, a netbook, a personal digital assistant (personal digital assistant, PDA), a wearable device, or augmented reality (AR)/virtual reality (VR) Devices, etc., the embodiments of the present application do not impose any restrictions on the specific types of electronic devices.

In the embodiment of the present application, the processor 110 may run instructions stored in the internal memory 121 to perform fine-grained control of resource usage according to processes in the background application. In addition, for different processes in the background application, the electronic device can perform different levels of resource management and control. Among them, the electronic device can control the resources of some processes in the background application regardless of control or weak control, and control the resources of other processes strongly. Therefore, compared with the prior art allowing each process in the background application program to use various resources normally, the resource management and control method provided by the embodiment of the present application can reduce the resource consumption of each background application program and reduce the power consumption of the electronic device.

The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes an Android system with a layered architecture as an example to illustrate the software structure of the electronic device 100 by way of example.

FIG. 3 is a software structure block diagram of the electronic device 100 according to an embodiment of the present application. The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Communication between layers through software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer. The application layer can include a series of application packages.

As shown in Figure 3, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 3, the application framework layer can include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and so on.

The window manager is used to manage window programs. The window manager can obtain the size of the display, determine whether there is a status bar, lock the screen, take a screenshot, etc.

The content provider is used to store and retrieve data and make these data accessible to applications. Data can include videos, images, audios, phone calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls that display text, controls that display pictures, and so on. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon may include a view that displays text and a view that displays pictures.

The phone manager is used to provide the communication function of the electronic device 100. For example, the management of the call status (including connecting, hanging up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc., and can also be used to fine-grain and control the resources of the background application according to the process.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and it can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, and so on. The notification manager can also be a notification that appears in the status bar at the top of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, text messages are prompted in the status bar, prompt sounds, electronic devices vibrate, and indicator lights flash.

Android Runtime includes core libraries and virtual machines. Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function functions that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), etc.

The surface manager is used to manage the display subsystem and provides a combination of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to realize 3D graphics drawing, image rendering, synthesis, and layer processing.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver. The kernel layer can also include some network protocols for controlling TCP connections and network resources.

In the embodiment of the present application, the resource manager in the application framework layer can perform fine-grained management and control of resource usage for the processes in the background application. Moreover, for different processes in the background application, the resource manager can perform resource management and control of different degrees and strengths. Therefore, compared with allowing each process in the background application program to use various resources normally, the resource management and control method provided in the embodiment of the present application can reduce the resource consumption of each background application program and reduce the power consumption of the electronic device.

In some embodiments, background applications may include critical processes and non-critical processes. Among them, the key process is an important process, or a process perceivable by the user. Electronic equipment can perform lesser and lesser resource management and control for key processes, and greater and more powerful resource management and control for non-critical processes.

The following will take the electronic device as a mobile phone with the structure shown in FIG. 2 and FIG. 3 as an example to illustrate the resource management and control method provided in the embodiment of the present application. Referring to Figure 4, the method may include:

401. After the mobile phone detects the first operation instructed by the user to open the first application, it runs the first application in the foreground.

Wherein, the first application program may be a system application program or a third-party application program, which is not limited in the embodiment of the present application. The user can instruct the mobile phone to open the first application by clicking on the icon of the first application program, voice commands, or gestures in the air, etc. in various ways.

For example, the first application is an instant messaging application, such as QQ, WeChat, facetime, or skype. Here, the first application is QQ as an example for description. Exemplarily, referring to FIG. 5A, the mobile phone detects the first operation of the user clicking the QQ icon 501; in response to the first operation, the mobile phone starts the QQ application in the foreground.

402. The mobile phone creates a process of the first application, and the process in the first application applies for resources.

After the mobile phone starts the first application, the process of the first application can be created. For example, when the first application is QQ, referring to Table 1, the mobile phone can create one or more of the QQ main process, the QQ tool process, the QQ space process, the QQ message receiving/sending process, and the download service process. Among them, the package name and the application program have a one-to-one correspondence and are fixed; each UID can correspond to one or more applications, and the UID corresponding to the application program may change after the application program is uninstalled and reinstalled.

Table 1

For another example, when the first application is WeChat, referring to Table 2, the mobile phone can create one or more of the WeChat main interface process, the WeChat message receiving/sending process, and the WeChat tool process.

Table 2

Wherein, each process in the first application program may apply for resources, and the resources may include the above-mentioned software resources and/or hardware resources to support the normal operation of various functional services of the first application program.

403. The mobile phone saves resource application information, where the resource application information includes the corresponding relationship between the process in the first application program and the requested resource.

When the mobile phone applies for resources in the process of the first application program, the resource application information can be saved through the resource manager. The resource application information includes the corresponding relationship between the process in the first application program and the requested resource. For example, the resource application information includes the process identity document (PID) and/or process name in the first application, and the corresponding relationship between the requested resource. In addition, the corresponding relationship may also include the package name and/or UID of the application.

In some embodiments, the corresponding relationship may also include related information such as application time and application duration of the resource applied for by the process.

Exemplarily, the package name of the first application program is package name 1, and the UID corresponding to the first application program is UID1. For a schematic diagram of the resource application information stored in the mobile phone, refer to FIG. 6A.

In some embodiments, the resource manager may include an application-level resource management module and a process-level resource management control module. The corresponding process of step 402 and step 403 can be seen in Fig. 6B.

404. The mobile phone displays the interface of the first application program.

After the mobile phone starts the interface of the first application program in the foreground, the interface of the first application program can be displayed on the screen. Exemplarily, a schematic diagram of the mobile phone displaying the QQ interface in the foreground can be seen in Fig. 5B.

It should be noted that there is no clear sequence relationship between step 403 and step 404. The first application may first apply for resources and then display the interface, or may display the interface before applying for resources, which is not limited in the embodiment of this application.

405. The mobile phone switches from running the first application program in the foreground to running the first application program in the background, and stops displaying the interface of the first application program.

In many cases, the mobile phone can run the first application program from the foreground and switch to the background operation of the first application program.

For example, when the first application is running in the foreground of the mobile phone, if the mobile phone detects the user's instruction to open another application, the mobile phone switches from running the first application in the foreground to running the first application in the background.

For another example, when the first application is running in the foreground of the mobile phone, if the mobile phone detects an operation instructing to open the desktop by the user, the mobile phone switches from running the first application in the foreground to running the first application in the background.

For another example, when the first application program is running in the foreground of the mobile phone, if the mobile phone detects the operation of the user instructing the screen to rest, the mobile phone switches from running the first application program in the foreground to running the first application program in the background.

For another example, when the first application is running in the foreground of the mobile phone, if the mobile phone detects that the user has not used the mobile phone for a long time and automatically turns off the screen, the mobile phone switches from running the first application in the foreground to running the first application in the background.

It is understandable that after the first application is switched from the foreground to the background, each process in the first application may also apply for resources, and the mobile phone may save the resource application information in the manner described in step 403.

406. The mobile phone determines the critical process and the non-critical process in the first application.

After the first application is switched to the background, the mobile phone can determine the critical process and non-critical process in the first application, so that the mobile phone can use different control methods for resource management and control for the critical process and the non-critical process. Among them, the key process is an important process, or a process perceivable by the user. There are many ways for a mobile phone to determine critical processes and non-critical processes.

In some embodiments, the mobile phone saves a list of critical processes and a list of non-critical processes. The mobile phone may determine the key process in the first application program according to the key process list, and determine the non-critical process in the first application program according to the non-critical process list.

For example, a process white list and a process black list are saved on the mobile phone. The process whitelist includes multiple critical processes of multiple applications, and the process blacklist includes multiple non-critical processes of multiple applications. If the first process in the first application is in the process whitelist, the mobile phone determines that the first process is a key process. If the first application program determines that the first process is in the process blacklist, the mobile phone determines that the first process is a non-critical process.

Exemplarily, when the first application is QQ, the QQ message receiving/sending process in the QQ process is in the white list, and the QQ message receiving/sending process is the key process. The QQ tool process in the QQ process is in the blacklist, so it is a non-critical process.

Illustratively again, when the first application is QQ, the QQ message receiving/sending process in the QQ process is in the whitelist, and the QQ message receiving/sending process is the key process. The main QQ process, the QQ tool process, and the QQ space process in the QQ process are in the blacklist, so they are non-critical processes.

In other embodiments, the process in the application program has a priority, and the mobile phone can determine whether the process in the first application program is a critical process or a non-critical process according to the priority of the process.

For example, in the Android operating system, the priority of a process can be represented by the ADJ value corresponding to the process. The smaller the ADJ value, the higher the priority of the process; the larger the ADJ value, the lower the priority of the process. For example, a process with an ADJ value less than or equal to the value of FORREGROUND_APP_ADJ is a critical process; a process with an ADJ value greater than the value of FORREGROUND_APP_ADJ is a non-critical process.

In other embodiments, the mobile phone may determine whether the process in the first background application is a critical process or a non-critical process according to the group to which the process belongs. For example, in the Android operating system, processes in the SCHED_GROUP_BACKGROUND group are non-critical processes, and processes in other groups (for example, the SCHED_GROUP_FOREGROUND group) are key processes.

In other embodiments, the mobile phone may determine whether the process in the first background application is a critical process or a non-critical process according to the service type used by the process. For example, in the Android operating system, the process that uses the foreground service in the first application program is a critical process, and the process that does not use the foreground service is a non-critical process.

In other embodiments, the mobile phone may determine the critical process and the non-critical process according to the function or type of the first application program. For example, if the first application is an instant messaging application, the message receiving/sending process is a key process. For another example, if the first application is a navigation application, the navigation process is a key process.

In other embodiments, the mobile phone can learn and recognize whether the process is a critical process or a non-critical process according to the characteristics of the process. Alternatively, the cloud server can learn and identify whether the process is a critical process or a non-critical process according to the characteristics of the process, and the mobile phone can obtain the identification result of the process from the cloud server.

For example, the key process can usually be a background process that is perceivable by the user. If the background processes meet the target characteristics shown in Table 3, which are usually associated with the user’s perception, the mobile phone can determine that these processes are user-perceivable message receiving/sending processes, alarm clock processes, uploading/downloading processes, and audio playback Key processes such as class process or navigation class process.

table 3

Specifically, referring to Figure 7, the mobile phone can collect heartbeats and network data packets according to the process, record notifications, vibrations, or collect other related information about the process. The mobile phone recognizes whether the process characteristics shown in Table 3 are satisfied according to the relevant information; if it is satisfied, the mobile phone determines that the process is a critical process; if not, the mobile phone determines that the process is a non-critical process. Among them, having network authority means that the process has the authority to use network resources and can use network resources normally.

Alternatively, the mobile phone can collect heartbeats and network data packets according to the process, record notifications, vibrations, or collect other related information of the process, and upload it to the cloud server. The cloud server recognizes whether the process characteristics shown in Table 3 are satisfied according to the relevant information of the process; if it is satisfied, the cloud server determines that the process is a critical process; if it is not satisfied, the cloud server determines that the process is a non-critical process. The cloud server returns the identification result of the process to the mobile phone.

For example, if the process of a mobile phone background application has the following characteristics: continuous sound playback, network, resident notification bar (that is, it often resides in the notification bar), and I/O operations. The mobile phone can determine that the process is a key process of the audio playback process.

It should be noted that the mobile phone or cloud service determines whether the process is a critical process or a non-critical process according to the process characteristics. This can be done every time the first application enters the background; it can also be learned and trained in advance, and the process recognition training can be saved result. For example, key processes obtained by pre-learning and training can be stored in the aforementioned process whitelist, and non-key processes obtained by pre-learning and training can be stored in the aforementioned process blacklist.

After determining the critical process and non-critical process in the first background application, the mobile phone executes step 407 and step 408 for the critical process and the non-critical process, respectively.

407. The mobile phone adopts the first management and control method for resource management and control for key processes.

408. The mobile phone uses the second management and control method for resource management and control for non-critical processes, and the second management and control method has a greater degree of resource management and control than the first management and control method for resources.

In step 407-step 408, the mobile phone can perform fine-grained management and control of the resource usage of the background application from the perspective of the process, and can perform different levels of resource management and control for the key and non-critical processes of the background application. Therefore, compared with the prior art allowing the normal resources of each process in the background application program, the resource management and control method provided in the embodiment of the present application can reduce the resource consumption of each background application program and reduce the power consumption of the electronic device.

In addition, the mobile phone uses resource management to process the first application in the background to protect the process of the first application without killing the process of the first application, so that the first application can continue to run in the background and in the background. When the first application is switched from the background to the foreground again, there is no need to load the process again, which can increase the speed at which the first application is started in the foreground, so that the interface of the first application is quickly displayed in the foreground.

After the first application has just switched to the background, there is a high probability that the user wants to use the first application in the foreground again in a short time. For example, when the user uses WeChat, the mobile phone receives a short message; when the user views the short message, WeChat switches to the background; when the user uses WeChat again after viewing the short message, WeChat switches to the foreground again. Therefore, in some embodiments, after the first application is switched to the background, the mobile phone may not immediately perform steps 407-408, so that when the mobile phone switches the first application from the background to the foreground again in a short time, it can be guaranteed The first application in the foreground can run normally. After the first application is switched to the background and the preset time period T has elapsed, the user may not want to use the first application again in the foreground in a short period of time. Therefore, the mobile phone can perform step 407-step 408 to update the first application in the background. The process of resource management and control.

In some embodiments, when the first application is switched from the foreground to the background when the mobile phone is on, the user is more likely to want to use the first application in the foreground again in a short period of time, and the preset duration T may be T1, T1 can be longer, for example, T1 can be 1 min. In the case that the first application is switched from the foreground to the background by the screen of the mobile phone, the probability that the user wants to use the first application in the foreground again in a short period of time is relatively small. The preset duration T can be T2, and T2 can be shorter. For example, T2 can be 6s.

When the phone is on, the first application is switched from the foreground to the background, and then the phone is off, if T1 ends before T2, the phone executes step 407-step 408 when T1 ends; if T2 ends before T1, Then the mobile phone executes step 407-step 408 at the end of T2. For example, T1 is 1min, T2 is 6s; the first application is switched to the background at time t1; after 20s (less than T1) after t1, that is, at time t2, the phone screen is off; after the screen is off, 6s( That is, at time t3 after the preset time period T2), the mobile phone executes step 407 to step 408. Among them, the time interval between time t3 and time t1 is less than 1 min.

In some other embodiments, after the first application is switched to the background, the mobile phone may not immediately perform step 406; after the first application is switched to the background and the preset time period T has elapsed, the user may not want to be in the foreground again in a short time. The first application program is used, so the mobile phone can perform step 406 to step 408 to perform resource management and control on the key processes and non-critical processes in the background first application program.

In some embodiments, the first management and control method is that the mobile phone allows the key processes of the first application in the background to use various resources normally, including the normal use of the resources that have been applied for, and the normal application of various resources, so that the first application The key process can run normally in the background. That is to say, the mobile phone does not limit the resource usage of the key process of the first application, and the first management and control method may be a control-independent method. Among them, the mobile phone can determine the corresponding relationship between the key process and the requested resource according to the resource application information.

In other embodiments, the first management and control mode is a weak management and control mode. That is, the mobile phone controls the key processes of the first application program in the background to a lesser degree and with less intensity, so as to make the key processes of the first application program continue to run in the background as far as possible. Specifically, the mobile phone can perform weak control over the key process according to the process identifier or process name of the key process.

For example, referring to Figure 8, the mobile phone's weak management and control methods for key processes can include: unify Alarm heartbeat according to the process; keep the TCP connection alive according to the process, and the TCP connection is continuously connected; does not limit the network permissions of the process; Use of resources such as job/broadcasting. In other words, weakly control the Alarm resources of key processes, allowing key processes to use other resources normally.

Among them, Alarm heartbeat is a heartbeat mechanism based on Alarm resources. Unifying the Alarm heartbeat by process means that the heartbeat packets based on Alarm resources are unified by process, that is, the heartbeat packets in the current key process are sent according to the preset cycle T3. The heartbeat packet refers to a custom command word between the client and the server to notify the other party of their own status at regular intervals, which is similar to the heartbeat, so it is called the heartbeat packet. Keep-alive TCP connection by process means that the TCP connection of the current key process is kept alive, and the Socket link used to realize the TCP connection is not broken.

Take the message receiving/sending service as an example. In order to ensure the timeliness of the message, the application needs to create a TCP connection in the background and maintain a long-term TCP connection with its server. Due to the requirements of the network protocol, the long connection maintained in the background requires regular data packet interaction. The application program (that is, the client (Client)) sends a keepalive data packet, that is, a heartbeat packet, to the server (Server). Referring to Figure 9, the client periodically wakes up the operating system through the Alarm. After the operating system is woken up, the client sends a heartbeat packet to the server, handshake with the server; and receives an acknowledgement (ACK) packet returned by the server. If a message or an order arrives at the client, the mobile phone running the client will remind the user, including multiple reminders such as notification bar message reminders, ring reminders or vibration reminders.

In some embodiments, the heartbeat packets of different key processes in the same application in the background can be sent in the same preset period T3 (for example, 5 min), which can reduce the number of times the operating system is awakened and reduce the power consumption of the mobile phone. .

In other embodiments, the heartbeat packets of different key processes in different applications in the background of the mobile phone can be sent in the same preset period T3, which can reduce the number of times the operating system is awakened and reduce the power consumption of the mobile phone.

Among them, the second control method is a strong control method, that is, the mobile phone controls the non-critical processes of the first application program in the background to a greater degree and with greater intensity. In some embodiments, the second control method is to restrict non-critical processes from using resources, including releasing resources requested by non-critical processes, that is, restrict non-critical processes from using resources that have been applied for, and restrict non-critical processes from applying for resources. Various resources. Among them, the mobile phone can determine the correspondence between the non-critical process and the requested resource according to the resource application information.

For example, referring to Figure 10, the strong control methods can include: pause Alarm heartbeat according to process; disconnect TCP connection according to process; limit network permissions according to process; buffer or discard broadcast according to process; pause GNSS/Wakelock/Job/ according to process Use of resources such as broadcasting.

Among them, suspending the Alarm heartbeat by process means stopping the current non-critical process based on the Alarm heartbeat packet. The TCP connection is through the Socket link for information exchange, and the TCP connection is disconnected according to the process, that is, the Socket link corresponding to the TCP connection of the current non-critical process is disconnected. Restricting network permissions by process refers to restricting the use of network resources by current non-critical processes. Suspending resources such as GNSS/Wakelock/Job/broadcast by process means that the current non-critical processes are prohibited from using resources such as GNSS/Wakelock/Job/broadcast. Among them, suspending broadcast resources by process includes caching or discarding broadcast content of current non-critical processes.

Take the Socket link resource of the TCP connection as an example. In the prior art, a process may include multiple Socket links. When the Socket link is disconnected, a four-way handshake interaction is required between the mobile phone and the server, and multiple data packets need to be sent. In addition, the disconnection time of different Socket links in the process is different. For example, after the Socket link has no message interaction time greater than or equal to the preset duration T4 (for example, it can be 8 minutes), the four-way handshake can be disconnected. The disconnection of multiple Socket links in the same process requires multiple message interactions, which consumes more resources and consumes more power.

In a solution provided by an embodiment of the present application, the Socket links in the same non-critical process can be disconnected uniformly at the same time. For example, after determining that the current process is a critical process, and the first application program enters the background for T duration, the mobile phone may uniformly disconnect the Socket links in the non-critical process. When the unified link is disconnected, the mobile phone can send a reset message (or RST packet) to the server. The reset message includes the source and destination IP addresses and port numbers of the Socket links in the non-critical process to notify The server uniformly disconnects the Socket link in the process. Therefore, the disconnection process does not require multiple message interactions, consumes less resources, and consumes less power.

Illustratively, take QQ as an example for description. After QQ runs, each QQ process creates multiple Socket links for TCP connections. For example, each QQ process creates 28 Socket links for TCP connections, of which 27 Socket links are created by the tool process application, and the other Socket link is created by the message receiving/sending process. If the method in the prior art is adopted, after QQ enters the background, the mobile phone allows each process of QQ to use resources normally according to the package name or UID, that is, all 28 Socket links are reserved.

In the embodiment of the present application, after QQ enters the background, the key process of QQ includes the message receiving/sending process, and the non-critical process includes the tool process. The mobile phone can allow the key process message receiving/sending process to normally use the 1 Socket link created, and disconnect the 27 Socket links created by the non-critical process tool process. Thus, the resource consumption of the background QQ can be reduced, and the power consumption of the mobile phone can be reduced.

In another solution provided by the embodiment of the present application, the Socket links in the non-critical processes in the same application can be disconnected at the same time. As a result, resource consumption can be reduced more, and the power consumption of the mobile phone can be reduced.

In other embodiments, the second management and control method is to restrict non-critical processes from using one or more resources. For example, taking QQ as an example, mobile phones can restrict non-critical processes from using Socket links and network resources, but allow non-critical processes to use Alarm resources normally.

It should be noted that in the case that the second management and control method includes both restriction of network permissions and disconnection of TCP connections, the mobile phone can further reduce resource consumption and power consumption. For example, if only the network permissions of non-critical processes are restricted and the TCP connection of non-critical processes is not disconnected, the mobile phone will still try to receive/send messages through the TCP connection. These messages are blocked at the network firewall of the mobile phone, but the mobile phone is still consumed. More resources and power consumption. If only the TCP connection of the non-critical process is disconnected, and the network permissions of the non-critical process are not restricted, the non-critical process may try to re-establish the TCP connection after disconnecting the TCP connection, which will consume more resources and power consumption of the mobile phone. .

In some embodiments, the key process may include multiple levels, the higher the level, the more important the key process, or the higher the level, the easier the function service of the key process is to be perceived by the user. Different levels of key processes can correspond to different first management and control methods. In addition, the higher the level of the key process, the smaller the control intensity of the corresponding first control method. This can minimize the resource consumption of other processes and reduce the power consumption of the mobile phone on the basis of ensuring the normal operation of the key process with a high level.

For example, the key process includes the first level, the second level, and the third level in descending order. Take Alarm heartbeat as an example. In the first control mode corresponding to the first level, the mobile phone does not control the Alarm heartbeat cycle in this critical process, that is, it does not control the use of Alarm resources; in the second level, the first control mode corresponds to In the key process, the alarm heartbeat cycle is 5min; in the first control mode corresponding to the third level, the alarm heartbeat cycle in the key process is 10min.

In other embodiments, the non-critical process may include multiple levels, and the lower the level of the non-critical process is, the less important it is, or the higher the level of the key process, the less likely it is to be perceived by the user. Different levels of non-critical processes can correspond to different second management and control methods. Moreover, the lower the level of non-critical processes, the greater the control intensity of the corresponding second control method, which can minimize the resource consumption of unimportant non-critical processes and reduce the power consumption of mobile phones.

For example, non-critical processes include first and second levels ranked from high to low. In the second management and control method corresponding to the first level, the mobile phone periodically restricts the use of resources by non-critical processes, that is, periodically allows and restricts the use of resources by non-critical processes. Taking network resources as an example, in the second management and control mode corresponding to the first level, the mobile phone periodically restricts the network permissions of non-critical processes, that is, periodically allows and restricts the use of network resources by non-critical processes. In the second management and control method corresponding to the second level, the mobile phone restricts the use of resources (such as network resources, etc.) by non-critical processes.

In some other embodiments, different key processes of the background application program may correspond to different key resources, and the key resources are used to support the main functions of the key process. The mobile phone can not control the key resources of the key process, and weakly or strongly control other resources, so as to reduce the resource and power consumption of the mobile phone by minimizing the use of resources.

For example, for instant messaging applications (such as QQ, WeChat, etc.), the message receiving/sending process is usually a key process, and the key resources corresponding to the message receiving/sending process include the TCP connection resources used to support the message receiving/sending function. , Network resources and Alarm resources. The mobile phone can allow the message receiving/sending process in the instant messaging application to use TCP connection resources, network resources, and Alarm resources normally; and weakly or strongly control other resources (such as GPS resources, broadcast resources, etc.) requested by the message receiving/sending process. Management and control (such as restricting or periodically restricting the use of other resources requested by the message receiving/sending process).

For another example, for navigation applications, the navigation process is usually a key process, and the key resources corresponding to the navigation process include GNSS resources and network resources for supporting navigation functions. The mobile phone can allow the navigation process in the navigation application program to use GNSS resources normally, and weakly or strongly control other resource processes applied for by the navigation process.

Exemplarily, referring to Table 4, the navigation application program 1 may include a navigation application main process, a navigation process, a push message process, and the like. Among them, the navigation process is a key process, and the key resources in the navigation process include GNSS resources and network resources.

For another example, referring to Table 5, the navigation application 2 may include a navigation application main process, a map navigation process, a patch update process, and so on. The map navigation process is a key process, and the key resources of the navigation process include GNSS resources and network resources.

Table 4

table 5

For another example, for an audio playback application, the playback process is usually a key process, and the key resources corresponding to the playback process include audio resources for supporting the audio playback function. In some embodiments, the key resource may also include network resources. The mobile phone can allow the playback process in the audio playback application to use audio resources normally, and weakly or strongly control other resource processes requested by the playback process.

Exemplarily, referring to Table 6 and Table 7, the audio playback application program 1 and the audio playback application program 2 may include an application main process and a playback process. Among them, the playback process is the key process, and the audio resources in the playback process are the key resources.

Table 6

Table 7

In addition, for other processes other than the critical process and non-critical process in the first background application, the mobile phone may not perform resource management and control, or the mobile phone may use a preset resource management method (for example, the resource management method in the prior art) to control it. Carry out resource management and control. For example, the QQ message receiving/sending process in QQ is a critical process, the QQ tool process is a non-critical process, and other processes such as the QQ main process and the QQ space process are critical processes and other processes other than non-critical processes. The mobile phone may not perform resource management and control on other processes such as the QQ main process and the QQ space process, or the mobile phone may use the resource management method in the prior art to perform resource management and control on other processes such as the QQ main process and the QQ space process.

After step 407 and step 408, the method may further include:

409. The mobile phone switches from running the first application program in the background to running the first application program in the foreground.

After the first application program is switched from the background to the foreground, each process in the first application program can use various resources normally to realize various functions and services of the first application program.

410. The mobile phone switches from running the first application program in the foreground to running the first application program in the background again.

After the first application is switched from the foreground to the background again, the mobile phone can use the resource management and control method described in the above embodiment to perform resource management and control on key processes and non-critical processes.

In some embodiments, after step 410, since the mobile phone has previously determined the key process and non-critical process of the first background application, the mobile phone can execute the direct step 407 and step 408, so as to check the information in the background first application. Resource management and control for critical and non-critical processes.

In other embodiments, after step 410, the mobile phone can perform step 406-step 408 to determine the critical process and non-critical process of the first background application program, and compare the critical process and non-critical process of the first background application program. Carry out resource management and control.
