Fig. 4 is a flowchart of a process freezing method according to an embodiment of the present application. The embodiment is described by only taking a terminal as an execution subject, and referring to fig. 4, the embodiment includes:

in step 401, the terminal detects application states of a plurality of applications, where the application states are used to indicate that a start event or an exit event occurs for a target application.

In the embodiment of the present application, the target application is used to refer to an application program with a changed application state at the current time.

In one possible implementation, step 401 may specifically include the following steps:

step 401A, if the terminal detects that the application state of the target application in the multiple applications changes, a notification data sending instruction is triggered, where the notification data sending instruction may carry application state information of the target application. And after receiving the trigger notification data sending instruction, the terminal executes the step of sending the notification data indicated by the trigger notification data sending instruction, and then performs subsequent operation of determining the application state according to the notification data.

Step 401B, the terminal determines the application state of the target application according to the application state information carried in the notification data sending instruction.

Optionally, the terminal may add the embedded point code for detecting the application state to the code for triggering detection in a manner of embedding the point code, so as to implement a function of detecting the application states of multiple applications.

It should be noted that step 401A may be implemented by a system framework unit in the system architecture, and step 401B may be implemented by a freezing management central control unit in the system architecture. Fig. 5 is a flow chart of a system for process freezing according to an embodiment of the present application, and as shown in fig. 5, after performing application exit background detection, a system framework unit triggers a notification data sending instruction, and sends notification data to a freezing management control unit. And the freezing management central control unit can determine the application state of the target application according to the application state information carried in the notification data.

In step 402, if a target application in the plurality of applications has an exit event, it is determined whether the target application is a third-party application program, and if the target application is the third-party application program, a process freeze instruction is triggered, where the third-party application program is a non-system-owned program.

In the embodiment of the application, the process freezing instruction is used for indicating a freezing processing mode of the query target application and freezing the process of the target application. The exit event may be an application interface shutdown or a switch to a background run.

In one possible implementation, the operating system of the terminal may store a list of programs that the system has, which may include names of the programs that the system has. If the target application exits, the terminal can query in a program list of the system according to the name of the target application, and judge whether a name matched with the name of the target application exists in the program list, if so, the target application is a non-third-party application program, and if not, the target application is a third-party application program. And if the target application is a third-party application program, triggering a process freezing instruction, and performing the freezing processing mode query operation indicated by the subsequent process freezing triggering instruction.

In order to ensure the normal operation of the system, when the exit event occurs to the application of the system, the process of the application does not need to be frozen, so that if the target application is a non-third-party application program, the step of triggering the process freezing instruction is not executed, and the corresponding operation of the subsequent target application is directly carried out. In the embodiment of the application, the normal operation of the system can be ensured by judging whether the target application is the third-party application program.

For example, the target application may be a music application, and when the application state of the music application is detected to be changed, the application state of the music application is determined, and if an exit event occurs to the music application, the step of triggering a process freeze instruction is performed. For another example, the target application may be an application provided by the system itself, such as a setting function, when detecting that an application state of the setting function changes, the application state of the setting function is determined, and if an exit event occurs in the setting function, the target application directly exits from the system background, and the step of triggering the process freeze instruction is not performed.

Optionally, the user may also preset a freeze blacklist, where the freeze blacklist is used to store an application that the user wants to perform a subsequent freeze process operation after exiting the application, for example, the video application may be placed in the freeze blacklist. When the terminal detects that the target application has an exit event, judging whether the target application is in a frozen blacklist, if so, executing a step of triggering a process freezing instruction, and if not, not executing a step of triggering the process freezing instruction. In another possible implementation manner, the user may also preset a frozen white list, where the frozen white list is used to store an application that the user does not want to perform a subsequent frozen process operation after exiting the application, for example, the chat-type application may be placed in the frozen white list. When the terminal detects that the target application has an exit event, judging whether the target application is in a frozen white list, if so, not executing the step of triggering the process freezing instruction, and if not, executing the step of triggering the process freezing instruction.

Optionally, if the target application is a third-party application program, the process of the target application may be added to the list of processes to be frozen, and used for subsequent query during operation of the frozen process.

In the embodiment of the present application, it is described as an example that if the target application has an exit event, it is determined whether the target application is a third-party application program. In another possible implementation manner, the terminal may not determine whether the target application is a third-party application program, and if the target application has an exit event, directly trigger the process freezing instruction, and then perform the subsequent operation. In addition, the step of determining, by the terminal, whether the target application is the third-party application program may be performed before determining the application state of the target application, that is, after the terminal receives the notification data that the application state of the target application changes, it may be determined first whether the target application is the third-party application program, and then the step of subsequently determining the application state may be performed. Or, the step of determining, by the terminal, whether the target application is the third-party application program may be after determining the application state of the target application, that is, after the terminal receives the notification data that the application state of the target application changes, the application state of the target application may be determined first, and then the subsequent determination step is performed. The order of the determination steps is not limited in the embodiments of the present application. In the embodiment of the application, whether the target application is the third-party application program or not is judged, the application needing to be frozen for operation can be quickly determined, and then the subsequent freezing process operation is carried out, so that the efficiency of the freezing process is improved.

It should be noted that step 402 can be implemented by the freezing management central control unit in the system architecture described above. If the target application has an exit event, as shown in fig. 5, the freezing management central control unit determines whether the target application is a third-party application program, and if so, triggers a process freezing instruction, and then the freezing management central control unit sends a freezing processing mode query request to the freezing policy management module.

In step 403, the terminal acquires the application type of the target application in response to the process freeze instruction for the target application.

In the embodiment of the present application, the application type refers to a type of a target application, such as a music-type application, a game-type application, a video-type application, a sports-type application, a navigation-type application, and the like. The Process freeze instruction may carry a name of the target application and a Process identifier, where the name may be a packet name of the target application, the packet name may be a segment of identifier code of the target application, and the Process identifier may be a PID (Process Identification, Process Identification number).

In a possible implementation manner, the process of the terminal obtaining the application type of the target application may include: after receiving the process freezing instruction of the target application, the terminal analyzes the process freezing instruction, and can obtain the name of the target application carried in the process freezing instruction. Based on the name of the target application carried in the process freezing instruction, the corresponding relation between the name and the application type is inquired, and the application type corresponding to the name can be obtained and used as the application type of the target application.

For example, the package name of the target application may be the media, and the correspondence between the name and the application type may be as shown in table 1.

TABLE 1

Name (R)	Identification	Application type
			mediacenter	A	Music (Music)
hwcamera	M	Camera (Camera)
			BaiduMap	N	Navigate (navigation)
mtxx	M	Camera (Camera)

According to the packet name of the target application, the corresponding relation between the name and the application type is inquired, the application type corresponding to the media can be Music, and the identifier can be A, so that the application type of the target application is determined to be Music application.

It should be noted that step 403 may be implemented by the freezing policy management unit in the system architecture described above. As shown in fig. 5, the freezing policy management unit receives the freezing processing mode query request, and queries the application classification identification unit according to the name of the target application carried in the freezing processing mode query request, so as to obtain the application type a of the target application, where the application classification identification unit may store a corresponding relationship between the name and the application type.

In step 404, the terminal responds to the process freezing instruction of the target application, and obtains the application running behavior of the target application.

In the embodiment of the present application, the application running behavior refers to a running behavior of the target application at the current time, such as playing music, downloading data, navigating, and the like. The target application may have one or more application running behaviors, and the target application may have multiple application running behaviors at the current time, for example, a music application may play music and download data at the same time.

In a possible implementation manner, the process of acquiring, by the terminal, the application running behavior of the target application may include: the process of the terminal acquiring the application running behavior of the target application may be as follows: and after the terminal acquires the name of the target application carried in the process freezing instruction, detecting according to the name to obtain the application running behavior of the target application corresponding to the name. According to the name of the target application, the application running behavior of the target application is detected, the application running behavior of the target application can be directly obtained, and the efficiency of obtaining the application running behavior of the target application is improved.

For example, the package name of the target application may be a media, and the application running behavior of the target application may be obtained by performing detection according to the package name, and may be stored in a table form, as shown in table 2.

TABLE 2

Name (R)	First application run behavior (identification)	Second application run behavior (identification)
			mediacenter	Is downloading data (B)	Music being played (C)

In table 2, according to the packet name query of the target application, two application running behaviors corresponding to the name media can be found, where a first application running behavior of the target application is downloading data, a flag may be B, a second application running behavior of the target application is playing music, and a flag may be C.

It should be noted that step 404 can be implemented by the freezing policy management unit in the system architecture described above. As shown in fig. 5, the freezing policy management unit queries the application behavior identification unit according to the name of the target application carried in the process freezing instruction, and may obtain the application running behavior B + C of the target application.

In step 405, the terminal determines importance information of the target application based on the application type and the application running behavior.

In the embodiment of the present application, the importance level information is used to indicate the possibility that the target application is used continuously, and the importance level information may be represented in a numerical form.

In one possible implementation, step 405 may specifically include the following steps:

in step 405A, the application configuration table may store application types of multiple applications and behavior weights of various corresponding behaviors. After the terminal obtains the application type and the application running behavior of the target application, based on the application type, the terminal queries in an application configuration table, and the behavior weights of various behaviors corresponding to the application type can be obtained. Based on the application running behavior of the target application, the behavior weight corresponding to the application running behavior can be determined in the behavior weights of various behaviors.

Step 405B, after the terminal obtains the application type, the application running behavior and the corresponding behavior weight of the target application, the terminal may calculate the application type, the application running behavior and the behavior weight corresponding to the application running behavior to obtain the importance information of the target application.

The behavior weight is a weight set for the application running behavior based on the user type, the behavior weight can be a numerical value, and the behavior weight can reflect the sustainability of the subsequent application use of the user. For example, the application running behavior may include navigation, downloading data, playing voice, and the like, for a navigation application, the behavior weight corresponding to the navigation may be set to a larger value, and the behavior weight corresponding to the playing voice may be set to a smaller value.

For example, the application type of the target application may be a music-like application, and the identifier may be a. The target application may correspond to one or more application execution behaviors, for example, a first application execution behavior of the target application may be data being downloaded, and the identifier may be B, and a second application execution behavior of the target application may be music being played, and the identifier may be C. The behavior weight of each type of behavior corresponding to the application type a in the application configuration table may be (x, y, z), then the behavior weight corresponding to the first application running behavior B may be x, and the behavior weight corresponding to the second application running behavior C may be y.

According to the above example, when the target application corresponds to two application running behaviors, the process of determining the importance information by the terminal may include: the terminal can obtain the importance information of the target application according to the application type, the application running behavior, the behavior weight corresponding to the application running behavior and the algorithm I ═ G (A, (B x + C y)). The method comprises the steps of obtaining importance degree information of a target application, obtaining importance degree information of the target application, obtaining importance degree.

It should be noted that step 405A and step 405B may be implemented by the freezing policy management unit in the system architecture. As shown in fig. 5, the freezing policy management unit queries the application configuration table in the freezing policy configuration unit according to the application type and the application running behavior, and may obtain the behavior weight (x, y) corresponding to the application running behavior B + C of the target application. The freezing strategy management unit calculates according to the application type of the target application, the application running behavior and the behavior weight corresponding to the application running behavior, and can obtain the importance degree information of the target application.

In step 406, the terminal determines a target freeze parameter matching the importance level information based on the importance level information.

In the embodiment of the application, the target freezing parameter is a freezing parameter of the target application and is used for indicating a freezing processing mode of the target application, and the target freezing parameter is matched with the application type and the application running behavior.

In a possible implementation manner, the process of determining, by the terminal, the target freeze parameter may include: after the terminal obtains the importance degree information of the target application, normalization (normalization) processing is carried out on the importance degree information, so that a freezing parameter identifier of the target freezing parameter can be obtained, and the freezing parameter identifier corresponds to the freezing processing mode of the target application. The terminal may store a correspondence between the freezing parameter identifier and the freezing parameter, and according to the freezing parameter identifier, the target freezing parameter may be obtained from the correspondence between the freezing parameter identifier and the freezing parameter, and the target freezing parameter may carry a freezing processing mode of the target application.

For example, the freezing parameter identifier of the target freezing parameter obtained by the terminal may be N, the target freezing parameter may be-1, 0, or 1, the freezing processing mode may be unfreezing when N is-1, the freezing processing mode may be immediate freezing when N is 0, and the freezing processing mode may be freezing with a delay of a preset time duration when N > is 1.

It should be noted that step 406 may be implemented by the freezing policy management unit in the system architecture described above. As shown in fig. 5, the freezing policy management unit performs normalization processing on the importance degree information to obtain a freezing parameter identifier of the target freezing parameter, and further obtains the target freezing parameter. And the freezing strategy management unit inquires an application configuration table in the freezing strategy configuration unit, can obtain a freezing processing mode matched with the target freezing parameter, and sends the target freezing parameter to the freezing bottom layer implementation unit.

In step 407, the terminal, in response to the target freezing parameter, freezes the process of the target application according to the freezing mode.

In this embodiment of the application, the freezing processing mode may include unfreezing, immediate freezing, and delaying freezing for a preset time duration, where the preset time duration may be a fixed time preset by a user, such as 3s, 4s, and the like.

In a possible implementation manner, after receiving the target freezing parameter, the terminal may determine a freezing processing manner matched with the target freezing parameter according to the target freezing parameter. And the terminal responds to the target freezing parameter indication to not execute the freezing processing, and then does not execute the freezing processing on the process of the target application. And the terminal responds to the target freezing parameter indication to immediately execute the freezing processing, and then the freezing processing is carried out on the process of the target application. And the terminal responds to the target freezing parameter indication to delay the preset time length to execute the freezing processing, and after the preset time length, the process of the target application is frozen.

For example, if the target freezing parameter of the target application indicates that the freezing process is not to be performed, after the target application exits the system background, the freezing process is not performed on the process of the target application, so that the process of the target application continues to occupy system resources and continues to run in the system background.

For another example, if the target freezing parameter indicates that the freezing process is to be executed immediately, according to the process identifier of the target application carried in the process freezing instruction, the process corresponding to the process identifier is queried in the process list to be frozen. Based on a linux group mechanism, the process is immediately migrated (migrate) to a Frozen group (freezing control process) group, so as to realize the freezing process of the process.

For another example, if the target freezing parameter indicates that the freezing process is executed with a delay of a preset time length, according to the process identifier of the target application carried in the process freezing instruction, the process corresponding to the process identifier is inquired in the process list to be frozen. Based on a linux group mechanism, after a preset time length, the process is migrated to a Frozen group, so that the freezing processing of the process is realized.

It should be noted that step 407 can be implemented by freezing the bottom-layer implementation unit in the system architecture described above. As shown in fig. 5, after the freezing bottom layer implementation unit receives the target freezing parameter, the freezing process is performed on the process of the target application according to the freezing processing mode indicated by the target freezing parameter.

It should be noted that, in the embodiment of the present application, multiple units may cooperate to complete, and in order to reduce code coupling between the units, the units such as the freezing management control unit and the freezing policy management unit may all separately implement corresponding tasks. As shown in fig. 5, the solid lines in fig. 5 indicate that the units individually implement the corresponding tasks, and the dotted lines indicate cross-process communication between the units.

In the above steps 401 to 407, the target application is taken as an example to generate an exit event and then perform the subsequent process freezing operation. In another possible implementation manner, if the target application has a starting event, whether the process of the target application is in a frozen state or not is detected, and if the process of the target application is in the frozen state, the process of the target application is unfrozen.
