Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a background process management method and terminal equipment, which can freeze an unnecessary and malicious background process to be incapable of being started, thereby saving memory, electric quantity and data flow and avoiding personal information and private data of a user from being stolen. The details will be described below.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a background process management method according to an embodiment of the present invention. The background process management method shown in fig. 1 may include the following steps:
101. the terminal equipment selects a target background process from currently running background processes; and the target background process is an unnecessary or malicious background process.
In the embodiment of the present invention, the terminal device may be a smart phone, a smart watch, a palm pc, a tablet pc, a Personal Digital Assistant (PDA), a point of sale (POS), or the like, and the following description of the embodiment of the present invention is omitted.
In the embodiment of the invention, in order to save the memory, the electric quantity and the data flow of the terminal equipment, unnecessary or malicious background processes can be screened from the currently running background processes on the terminal equipment, and the background processes are frozen to be closed and cannot be started. The malicious background process refers to a background process which can steal personal information and private data of a user by monitoring operations such as screen actions and keyboard input. The unnecessary background process refers to a background process corresponding to software or functions which are used by a user with extremely low frequency or even never used, such as a background process with a remote control function, a background process with a notebook of the system, a background process with a system search function, and the like. Such as a background process of the system search function, which is generally run by default as a power-on, i.e., registration event, however, the system search function is generally used less frequently by users and, therefore, may be considered frozen.
However, due to the difference in usage habits of users, some functions may be used very frequently, and users often use the functions due to personal habits. For the situation, the user can manually set the frozen background process list, so that the background process with the frequently-used function is prevented from being frozen.
In the embodiment of the invention, the terminal equipment can select some special moments to screen the background process which is currently running. As an optional implementation manner, the terminal device determines whether the current state is switched from the power-off state to the power-on state, and selects a target background process from currently running background processes if the current state is switched from the power-off state to the power-on state.
As an optional implementation manner, the terminal device receives an operation instruction for searching for a freezable background process by a user, and selects a target background process from currently running background processes according to the operation instruction.
As an optional implementation manner, the terminal device monitors whether a new background process is started, and selects a target background process from currently running background processes if the new background process is started.
In the embodiment of the invention, a user can preset the freezable background process list according to personal use habits, and the background process corresponding to the application and the function which are used at extremely low frequency or even unused is recorded into the freezable background process list. As an optional implementation manner, the terminal device monitors whether a new background process is started, and if the new background process is started, selects a background process in a background process list in the currently running background process as a target background process according to a freezable background process list preset by a user.
In the embodiment of the invention, the terminal equipment can also select the background process which evaluates the security software in the currently running background process as a non-essential or malicious process as the target background process according to the evaluation of the security software in the terminal equipment on the background process.
Preferably, in the android system, the background process may be a background service process. The background service process is derived from the service component, and the service component has the characteristics of background running, no operation interface and the like, can continuously update data and visible activities in the background, and can trigger the notification. For example, the functions of recording or other monitoring when a music player continuously plays in the background and makes a call can be realized by the service component. Thus, it is necessary to determine the background service process as the target background process, so as to freeze it.
102. And the terminal equipment stops the target background process from running.
In the embodiment of the invention, after the terminal device screens out the target background process (namely the background process needing to be frozen), the background process stops running, and data and logs are stored so as to prevent the data loss caused by forcibly closing the background process.
103. And the terminal equipment sends a freezing instruction to the target background process so that the target background process is closed and cannot be started.
In the embodiment of the invention, after stopping the target background process to be frozen, the terminal equipment stores data and logs, and then sends a freezing instruction to the target background process, the target background process carries out closing operation according to the freezing instruction, and modifies corresponding parameters into non-startable state until the target background process can be started normally after being thawed.
In the method shown in fig. 1, the terminal device may screen the currently running background processes when the terminal device is just started or a new background process appears, where the terminal device may screen the background processes that need to be frozen in the currently running background processes according to a freezable background process list preset by a user or an evaluation of the background processes by security software. After the background process needing to be frozen is selected, the terminal equipment stops the background process and sends a freezing instruction to the background process to enable the background process to be closed and not started. Therefore, by implementing the method, the unnecessary and malicious background process can be frozen and cannot be started, so that the functions of saving the memory, saving the electric quantity and the data flow and avoiding the personal information and the private data of the user from being stolen are achieved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another background process management method according to an embodiment of the present invention. As shown in fig. 2, the method may include the steps of:
201. the terminal equipment selects a target background process from currently running background processes; and the target background process is an unnecessary or malicious background process.
In the embodiment of the invention, in order to save the memory, the electric quantity and the data flow of the terminal equipment, unnecessary or malicious background processes can be screened from the currently running background processes on the terminal equipment, and the background processes are frozen to be closed and cannot be started. The malicious background process refers to a background process which can steal personal information and private data of a user by monitoring operations such as screen actions and keyboard input. The unnecessary background process refers to a background process corresponding to software or functions which are used by a user with extremely low frequency or even never used, such as a background process with a remote control function, a background process with a notebook of the system, a background process with a system search function, and the like. Such as a background process of the system search function, which is generally run by default as a power-on, i.e., registration event, however, the system search function is generally used less frequently by users and, therefore, may be considered frozen.
However, due to the difference in usage habits of users, some functions may be used very frequently, and users often use the functions due to personal habits. For the situation, the user can manually set the frozen background process list, so that the background process with the frequently-used function is prevented from being frozen.
In the embodiment of the invention, the terminal equipment can select some special moments to screen the background process which is currently running. As an optional implementation manner, the terminal device determines whether the current state is switched from the power-off state to the power-on state, and selects a target background process from currently running background processes if the current state is switched from the power-off state to the power-on state.
As an optional implementation manner, the terminal device receives an operation instruction for searching for a freezable background process by a user, and selects a target background process from currently running background processes according to the operation instruction.
As an optional implementation manner, the terminal device monitors whether a new background process is started, and selects a target background process from currently running background processes if the new background process is started.
In the embodiment of the invention, a user can preset the freezable background process list according to personal use habits, and the background process corresponding to the application and the function which are used at extremely low frequency or even unused is recorded into the freezable background process list. As an optional implementation manner, the terminal device monitors whether a new background process is started, and if the new background process is started, selects a background process in a background process list in the currently running background process as a target background process according to a freezable background process list preset by a user.
In the embodiment of the invention, the terminal equipment can also select the background process which evaluates the security software in the currently running background process as a non-essential or malicious process as the target background process according to the evaluation of the security software in the terminal equipment on the background process.
Preferably, in the android system, the background process may be a background service process. The background service process is derived from the service component, and the service component has the characteristics of background running, no operation interface and the like, can continuously update data and visible activities in the background, and can trigger the notification. For example, the functions of recording or other monitoring when a music player continuously plays in the background and makes a call can be realized by the service component. Thus, it is necessary to determine the background service process as the target background process, so as to freeze it.
202. And the terminal equipment stops the target background process from running.
In the embodiment of the invention, after the terminal device screens out the target background process (namely the background process needing to be frozen), the background process stops running, and data and logs are stored so as to prevent the data loss caused by forcibly closing the background process.
203. And the terminal equipment judges whether the target background process is allowed to be frozen or not according to the priority of the target background process.
In the embodiment of the invention, the background processes running in the system all have corresponding priorities, and the priorities determine when the background processes run and how much CPU time is occupied. The essential basic functions in the system generally have high priority, such as a task manager, key input monitoring and the like, and some applications also set higher priority for their own background processes in order to ensure their own operating quality. If the background process with the high priority is frozen, the normal use of the terminal equipment is probably influenced, so that the terminal equipment judges the priority of the target background process, and if the priority is high, the background process is judged not to be allowed to be frozen; if the priority is normal, the background process is judged to be allowed to be frozen.
204. And if the target background process is allowed to be frozen, the terminal equipment sends a freezing instruction to the target background process so that the target background process is closed and cannot be started.
In the embodiment of the invention, after stopping the target background process to be frozen, the terminal equipment stores data and logs, and then sends a freezing instruction to the target background process, the target background process carries out closing operation according to the freezing instruction, and modifies corresponding parameters into non-startable state until the target background process can be started normally after being thawed.
205. The terminal equipment monitors whether an application program depending on a target background process is started.
In the embodiment of the invention, the terminal equipment freezes on the level of the process, and when a user operates the application from the terminal equipment, the user cannot find whether one or more processes corresponding to the application are frozen, so that trouble can be caused to the user using the application in the terminal equipment. Therefore, the terminal device needs to monitor whether an application dependent on a target background process (frozen background process) is started, and if so, the terminal device needs to ask whether the user unfreezes the background process to ensure normal use of the application.
206. And if the application program depending on the target background process is started, the terminal equipment sends a prompt message to the user to inquire whether the user unfreezes the target background process.
In the embodiment of the invention, when the terminal device monitors that the application program depending on the frozen background process is started, a prompt message is sent to the user to inquire whether the user unfreezes the background process or not so as to enable the application program to be normally used.
In the method described in fig. 2, the terminal device may screen out the background process that needs to be frozen from the currently running background processes according to a freezable background process list preset by the user or evaluation of the background process by the security software, then stop the background process, and send a freeze instruction to the background process to shut down the background process and disable starting. After the background process is frozen, if the application program depending on the background process is monitored to be started, a prompt message is sent to a user to inquire whether the background process needs to be unfrozen or not, so that the application program can be normally used. Therefore, by implementing the method, the unnecessary and malicious background process can be frozen and cannot be started, so that the functions of saving the memory, saving the electric quantity and the data flow and avoiding the personal information and the private data of the user from being stolen are achieved. In addition, the terminal equipment can prompt the user to unfreeze the background process in time, so that the normal use of the application program which the user wants to use is not influenced.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a terminal device according to an embodiment of the present invention. As shown in fig. 3, the terminal device may include:
a screening unit 301, configured to select a target background process from currently running background processes; the target background process is an unnecessary or malicious background process;
in the embodiment of the invention, in order to save the memory, the electric quantity and the data flow of the terminal equipment, unnecessary or malicious background processes can be screened from the currently running background processes on the terminal equipment, and the background processes are frozen to be closed and cannot be started. The malicious background process refers to a background process which can steal personal information and private data of a user by monitoring operations such as screen actions and keyboard input. The unnecessary background process refers to a background process corresponding to software or functions which are used by a user with extremely low frequency or even never used, such as a background process with a remote control function, a background process with a notebook of the system, a background process with a system search function, and the like. Such as a background process of the system search function, which is generally run by default as a power-on, i.e., registration event, however, the system search function is generally used less frequently by users and, therefore, may be considered frozen.
However, due to the difference in usage habits of users, some functions may be used very frequently, and users often use the functions due to personal habits. For the situation, the user can manually set the frozen background process list, so that the background process with the frequently-used function is prevented from being frozen.
In this embodiment of the present invention, the screening unit 301 may select some special times to screen the currently running background process. As an optional implementation manner, the screening unit 301 determines whether the current state is converted from the power-off state to the power-on state, and selects a target background process from currently running background processes if the current state is converted from the power-off state to the power-on state.

As an optional implementation manner, the screening unit 301 monitors whether a new background process is started, and selects a target background process from currently running background processes if the new background process is started.
In the embodiment of the invention, a user can preset the freezable background process list according to personal use habits, and the background process corresponding to the application and the function which are used at extremely low frequency or even unused is recorded into the freezable background process list. As an optional implementation manner, the screening unit 301 monitors whether a new background process is started, and if the new background process is started, selects a background process in a background process list from currently running background processes as a target background process according to a freezable background process list preset by a user.
In this embodiment of the present invention, the screening unit 301 may further select, as the target background process, a background process in which the security software in the currently running background process is evaluated as an unnecessary or malicious process according to the evaluation of the security software in the terminal device on the background process.
Preferably, in the android system, the background process may be a background service process. The background service process is derived from the service component, and the service component has the characteristics of background running, no operation interface and the like, can continuously update data and visible activities in the background, and can trigger the notification. For example, the functions of recording or other monitoring when a music player continuously plays in the background and makes a call can be realized by the service component. Thus, it is necessary to determine the background service process as the target background process, so as to freeze it.
A termination unit 302, configured to stop the target background process;
in the embodiment of the present invention, after the screening unit 301 screens out a target background process (i.e., a background process that needs to be frozen), the terminating unit 302 stops the background process from running, and stores data and logs to prevent data loss caused by forcibly closing the background process.
A first sending unit 303, configured to send a freeze instruction to the target background process, so that the target background process is turned off and cannot be started.

In the terminal device shown in fig. 3, the screening unit 301 may screen the currently running background process when the terminal device is just started or a new background process appears, where the screening unit 301 may screen the background process that needs to be frozen in the currently running background process according to a freezable background process list preset by a user or an evaluation of the background process by security software. After the background process to be frozen is selected, the terminating unit 302 stops the background process, and the first sending unit 303 sends a freezing instruction to the background process, so that the background process is closed and cannot be started. Therefore, by utilizing the terminal equipment, unnecessary and malicious background processes can be frozen and cannot be started, so that the functions of saving memory, saving electric quantity and data flow and avoiding the personal information and private data of a user from being stolen are achieved.
Referring to fig. 4, fig. 4 is a schematic structural diagram of another terminal device according to an embodiment of the present invention. Wherein, the terminal device shown in fig. 4 is obtained by optimizing the terminal device shown in fig. 3, and compared with the terminal device shown in fig. 3, the terminal device shown in fig. 4 further includes:
a monitoring unit 304, configured to monitor whether an application dependent on the target background process is started.
In the embodiment of the invention, the terminal equipment freezes on the level of the process, and when a user operates the application from the terminal equipment, the user cannot find whether one or more processes corresponding to the application are frozen, so that trouble can be caused to the user using the application in the terminal equipment. Therefore, the monitoring unit 304 needs to monitor whether an application that depends on the target background process (the frozen background process) is started, and if so, the user needs to be asked whether to unfreeze the background process to ensure the normal use of the application.
A second sending unit 305, configured to send a prompt message to the user to ask the user whether to unfreeze the target background process when an application dependent on the target background process is started.
In this embodiment of the present invention, when the monitoring unit 304 detects that an application program that depends on a frozen background process is started, the second sending unit 305 sends a prompt message to the user to inquire whether the user unfreezes the background process, so that the application program can be used normally.
As an optional implementation, the first sending unit 303 includes:
a first determining subunit 3031, configured to determine, according to the priority of the target background process, whether the target background process is allowed to be frozen.
In the embodiment of the invention, the background processes running in the system all have corresponding priorities, and the priorities determine when the background processes run and how much CPU time is occupied. The essential basic functions in the system generally have high priority, such as a task manager, key input monitoring and the like, and some applications also set higher priority for their own background processes in order to ensure their own operating quality. If the background process with the high priority is frozen, the normal use of the terminal device is likely to be affected, so that the first judgment subunit 3031 judges the priority of the target background process, and if the priority is high, the judgment is made that the background process is not allowed to be frozen; if the priority is normal, the background process is judged to be allowed to be frozen.
A sending subunit 3032, configured to send a freeze instruction to the target background process when the target background process is allowed to be frozen, so that the target background process is closed and cannot be started.

a receiving subunit 3013, configured to receive an operation instruction for a user to search for a freezable background process; the second screening subunit 3014 is configured to select a target background process from currently running background processes according to the operation instruction; alternatively, the first and second electrodes may be,
a monitoring subunit 3015, configured to monitor whether a new background process is started; and a third screening subunit 3016, configured to, when a new background process is started, select a target background process from currently running background processes.
In the terminal device described in fig. 4, the terminal device may screen out a background process that needs to be frozen from currently running background processes according to a freezable background process list preset by a user or evaluation of the background process by security software, then stop the background process, and send a freeze instruction to the background process to shut down the background process and disable starting. After freezing the background process, if the monitoring unit 304 monitors that an application program dependent on the background process is started, the second sending unit 305 sends a prompt message to the user to inquire whether the background process needs to be thawed, so that the application program can be normally used. Therefore, by implementing the method, the unnecessary and malicious background process can be frozen and cannot be started, so that the functions of saving the memory, saving the electric quantity and the data flow and avoiding the personal information and the private data of the user from being stolen are achieved. In addition, the terminal equipment can prompt the user to unfreeze the background process in time, so that the normal use of the application program which the user wants to use is not influenced.

The memory 502 may be used to store software programs and modules, and the processor 508 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 502. The memory 502 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 502 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 503 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 503 may include a touch panel 5031 and other input devices 5032. The touch panel 5031, also called a touch screen, can collect a touch operation performed by a user on or near the touch panel 5031 (e.g., an operation performed by the user on or near the touch panel 5031 by using any suitable object or accessory such as a finger or a stylus pen), and drive a corresponding connection device according to a preset program. Alternatively, the touch panel 5031 may include two parts, namely, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 508, and can receive and execute commands sent by the processor 508. In addition, the touch panel 5031 can be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 503 may include other input devices 5032 in addition to the touch panel 5031. In particular, other input devices 5032 can include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 5041 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 5041 and/or backlight when the phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.
WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 507, and provides wireless broadband internet access for the user. Although fig. 5 shows the WiFi module 507, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 508 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 502 and calling data stored in the memory 502, thereby performing overall monitoring of the mobile phone. Alternatively, processor 508 may include one or more processing units; preferably, the processor 508 may integrate an application processor, which primarily handles operating systems, user interfaces, application programs, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 508.
The handset also includes a power supply 509 (e.g., a battery) for powering the various components, which may preferably be logically connected to the processor 508 via a power management system, so that the power management system may be used to manage charging, discharging, and power consumption.
