Step 320, if runing time reaches preset time threshold, the backstage for having incidence relation with foreground application is obtained Process.

Process (Process) is program in computer about the primary operation activity on certain data acquisition system, be system into The basic unit of row Resource Distribution and Schedule is the basis of operating system configuration.Can usually have been run on mobile terminal it is multiple into Journey, different processes can be used for executing different tasks respectively.When mobile terminal listens to foreground application starting, can record should In the time of front stage operation after foreground application starting.If reaching preset time in the time of front stage operation after foreground application starting Threshold value, mobile terminal can obtain the currently background process for having incidence relation with foreground application in running background.Optionally, it moves Dynamic terminal can be obtained by active manager currently to exist in each process of running background, and according to the application identities of foreground application The background process for having incidence relation with foreground application is currently inquired in each process of running background.Mobile terminal can be preparatory The incidence relation of storage application and process starts when listening to foreground application, and in the operation on foreground after foreground application starting When time reaches preset time threshold, it can be obtained according to the application identities of foreground application and have incidence relation with the foreground application Background process.

Optionally, the background process for having incidence relation with foreground application, which can be, has communication mechanism with foreground application Background process has the background process of call relation with foreground application, or after belonging to same system's publisher with foreground application Platform process etc., but not limited to this.Communication mechanism refers to being propagated or exchanged letter between different processes and/or application Breath.Optionally, communication mechanism may include socket, binder, shared drive etc., wherein two programs on network pass through one The exchange of data is realized in a two-way communication connection, and one end of this connection is known as a socket；Binder is a kind of process Between communication mechanism, remote procedure call function is provided；Shared drive is exactly to allow two incoherent process access are same to patrol Memory is collected, shared drive is a kind of very effective mode that data are shared and transmitted between the process being currently running at two, The memory shared between different processes is usually arranged for same section of physical memory.After call relation refers to that foreground application can be called Platform process executes corresponding task, for example the log-on message of background process storage is called to carry out register, wherein log-on message It refers to the information such as the account information, the password that can be used for logging in, or background process is called to position etc., but not limited to this. Publication label identical with foreground application can be carried with the background process that foreground application belongs to same system's publisher, the publication mark Label can be used for identifying the publisher of release application program.

Step 330, the state of the determining background process for having incidence relation with foreground application.

Mobile terminal can obtain the state of each background process for having incidence relation with foreground application of generation, optional Ground, the state of background process may include but be not limited to frozen state and thawed state etc..Frozen state refer to background process without Method is using resources such as CPU ,/O and networks, and in the state that can not be continued to run, but the background process can still occupy memory Resource, hard disk resources etc.；Thawed state refers to that the system resources such as CPU, I/O, memory and network can be used in background process, is in The state of execution task can be run.

In one embodiment, mobile terminal can obtain with foreground application have incidence relation after the frozen state Platform process.Optionally, mobile terminal can obtain the state tag for each background process for having incidence relation with foreground application, no Same state can be indicated with different state tags, for example, the corresponding state tag of frozen state is 0, thawed state pair The state tag answered is 1 etc., but not limited to this.Mobile terminal can according to each backstage for having incidence relation with foreground application into The state tag of journey obtains the background process for being in frozen state.

Optionally, mobile terminal can also be communicated to each background process transmission for having incidence relation with foreground application respectively Signal, and detect whether to receive response signal within a predetermined period of time.If not receiving process within a predetermined period of time to return The response signal returned then can determine that the state for not sending the background process of response signal is frozen state.It is to be appreciated that Other modes can be used and obtain and have the background process in frozen state of incidence relation with foreground application, be not limited on State several ways.

Step 340, it if the state of background process is frozen state, thaws to background process.

It, can will be at this after acquisition for mobile terminal and foreground application have the background process in frozen state of incidence relation It thaws in the background process of frozen state.Mobile terminal can to foreground application have incidence relation in frozen state Background process send defrosting information, so that background process is entered thawed state by defrosting signal, CPU, I/O, interior can be used It deposits and the system resources such as network, operation can be normally carried out and execute task.When foreground application need in operation using have close When the background process of connection relationship, without thawing again to background process, the speed of response can be improved.In addition, only thawing with before Platform application has the background process of incidence relation, freezes entire application belonging to background process without demodulating, it is possible to reduce system disappears Consumption.

Optionally, mobile terminal can obtain the background process for having communication mechanism with foreground application, and determination is answered with foreground With the state for the background process for having communication mechanism.Mobile terminal can have communication equipment with foreground application in frozen state The background process of system thaws, and the background process after defrosting can be communicated normally with foreground application.It can guarantee that foreground is answered With the normal communication with background process, the system speed of response is improved.

In the present embodiment, when listening to foreground application starting, after record foreground application starting in the operation on foreground Between, if runing time reaches preset time threshold, the background process for having incidence relation with foreground application is obtained, and in jelly The background process for having incidence relation of knot state thaws, can be to the background process for having incidence relation with foreground application It thaws, when reducing the waiting that foreground application needs to thaw again using the background process for having incidence relation in operation Between, accelerate the system speed of response.

As shown in figure 4, in one embodiment, it is further comprising the steps of after step thaws to background process:

Step 402, the operation characteristic for the background process for having incidence relation with foreground application is obtained.

It, can after mobile terminal pair thaws with the background process in frozen state that foreground application has incidence relation The operation characteristic for each background process for having incidence relation with foreground application is obtained, operation characteristic may include but be not limited to backstage The currently performed task of process, with the communication event of other processes and/or application etc., the resource type and ratio that currently occupy Deng.

Step 404, the resource constraint grade for having the background process of incidence relation is determined according to operation characteristic.

Mobile terminal can analyze the operation characteristic for each background process for having incidence relation with foreground application, and The resource constraint grade of corresponding background process is determined according to operation characteristic.Optionally, mobile terminal can be set according to actual needs Different resource constraint grades, resource constraint grade can be used for indicating that, using the confined degree of resource, resource constraint grade is got over Height, restricted degree can be bigger.Restricted resource may include but be not limited to cpu resource, memory source, I/O resource, network Resource etc..Different resource constraint grades can correspond to different resource use priorities, and resource constraint higher grade, corresponding money Source use priority can be smaller, and resource constraint lower grade, and corresponding resource use priority can be bigger.

In one embodiment, the resource constraint grade of mobile terminal setting may include without limitation rank, common limiter stage Not, depth limit rank and freeze rank etc..It is unrestricted to may refer to the resource that process uses without limitation rank.Common limitation Rank, which may refer to process, can be used less resource, for example 50% resource etc. at most only can be used, but not limited to this.Depth Limitation rank, which may refer to process, can be used few resource, for example 20% resource etc. at most only can be used, but not limited to this. Freeze rank and refer to that process is not available any resource, stops all behaviors of process.For example, foreground application can correspond to nothing Rank is limited, the resource that foreground application uses is unrestricted；If with foreground application have the background process of incidence relation not with Foreground application is communicated, then can correspond to depth limit rank, and few resource etc. can be used, but not limited to this.

Step 406, the background process that will be provided with incidence relation is assigned in resource group corresponding with resource constraint grade, And configure resource use priority corresponding with resource constraint grade.

After mobile terminal determines the resource constraint grade for each background process for having incidence relation with foreground application, it can incite somebody to action And each background process that foreground application has incidence relation is assigned to resource group corresponding with the resource constraint grade determined In, and configure resource use priority corresponding with resource constraint grade.Optionally, mobile terminal can be based on kernel Cgroup (control group) mechanism divides different resource groups, and file node can be used writes the mode of configuration and each money is arranged The other resource use priority of source group, to the process being assigned in each resource group using resource time or ratio etc. into Row management, wherein Cgroup is that the one kind provided in kernel can be limited, be recorded, physical resource used in isolated process (compares Mechanism such as: CPU, memory, I/O resource).Mobile terminal can load the configuration file of Cgroup, can record in configuration file There are the resource group, the other resource use priority of each resource group and scheduling of resource corresponding with resource use priority of division Strategy.Resource dispatching strategy may include but be not limited to the process being assigned in resource group and be provided using the time of resource, occupancy Source ratio, the resource identification used etc., for example, the corresponding other process of resource group of configurable common limitation rank is in 1 minute 30 seconds cpu resources can be used, and the corresponding other process of resource group of common limitation rank is only capable of providing using the CPU that number is X Source etc., but not limited to this.When needing to add new resource group, or the other resource use priority of modification resource group and resource Scheduling strategy can pass through the configuration file of modification Cgroup.

Mobile terminal will be assigned to and resource constraint grade pair with each background process that foreground application has incidence relation In the resource group answered, and after configuration resource use priority corresponding with resource constraint grade, has with foreground application and be associated with The background process of relationship can use the resources such as CPU, memory, I/O and network according to the corresponding resource dispatching strategy of resource group. In one embodiment, mobile terminal can at regular intervals section obtain with foreground application have each backstage of incidence relation into The operation characteristic of journey, and the resource constraint grade for having the background process of incidence relation is determined according to operation characteristic.It is answered with foreground It can be changed with the variation of operation characteristic with the resource constraint grade for the background process for having incidence relation.After for example, After platform process terminates the communication with foreground application, resource constraint grade of the background process etc. can be improved, but not limited to this.

Fig. 5 is the other schematic diagram of resource group in one embodiment.As shown in figure 5, can set in mobile terminal, there are four not Same resource constraint grade, and there are four resource groups for division, wherein first resource group is corresponding to be provided without limitation rank, second The corresponding common limitation rank of source group, information resources group correspond to depth limit rank, and the 4th resource group correspondence freezes rank. Four resource groups can respectively correspond different resource use priorities, and the other resource use priority of first resource group can be higher than Secondary resource group, the other resource use priority of Secondary resource group can be higher than information resources group, the other money of information resources group Source use priority can be higher than the 4th resource group.The first resource group CPU that limiting process does not use, interior without limitation rank It deposits, the resources such as I/O and network.Less CPU, memory, I/O can be used in the common other Secondary resource group limiting process of limiter stage And the resources such as network.Few CPU, memory, I/O and network can be used in the information resources group limiting process of depth limit rank Etc. resources.Freeze the resources such as the unusable CPU of the 4th resource group limiting process, memory, I/O and the network of rank.It is mobile whole End determines resource constraint grade according to the operation characteristic of each background process for having incidence relation with foreground application, and will with it is preceding Each background process that platform application has incidence relation is added in corresponding resource group, configures money corresponding with resource group Source use priority is managed to the resource that each background process that foreground application has incidence relation uses.

In the present embodiment, resource can be determined according to the operation characteristic for the background process for having incidence relation with foreground application Limit grade, to the different grades of resource constraint of background process dynamic implement for having incidence relation with foreground application, to The background process that foreground application has incidence relation thaws, and while improving the system speed of response, reduction has association and closes The background process of system seizes the resource of foreground application, and optimization system performance saves power consumption.

As shown in fig. 6, in one embodiment, above- mentioned information processing method is further comprising the steps of:

Step 602, have the operation characteristic of the background process of incidence relation with foreground application by kernel spacing acquisition, and Operation characteristic is packaged into data packet and sends user's space to.

It may include having kernel spacing and user's space in the Virtual Space of mobile terminal, kernel spacing can be used for storing kernel Code and data, user's space can be used for storing the code and data of application program.Kernel spacing possesses higher level of privilege Not, the process run in kernel spacing can possess the permission of all hardware of access mobile terminal, and the permission of user's space is then Lower, the part resource of system only can be used in the process run in the user space.

Mobile terminal can acquire the event for each background process for having incidence relation with foreground application by kernel spacing Data, event data may include but be not limited to event type, event time, event content, process identification (PID) belonging to event etc..Thing Part type may include but be not limited to communication event, creation event, exit event, change identified event, task events etc..Communicate thing Part may refer to the communication event of process and other application and/or process, it may include binder communication event and socket communication Event etc..Creation event may refer to the event that process etc. is created.The event of exiting refers to the event that process exits.Change mark Knowledge event may refer to the mark etc. that process changes itself.Task events may refer to the task dispatching of process execution.

Mobile terminal has the event number of each background process of incidence relation by kernel spacing acquisition with foreground application According to the operation characteristic for each background process for having incidence relation with foreground application can be extracted from event data, and can be according to Operation characteristic is packaged into data packet and sends user's space to by the packet format of agreement.Optionally, kernel spacing and user's space can It is communicated by the way of asynchronous netlink, netlink is that a kind of consumer process that may be implemented is communicated with kernel process A kind of special interprocess communication.Kernel spacing is by way of asynchronous communication by the fortune for each process for including in invocation list Row feature is transferred to user's space, more efficient and convenient compared to the mode for playing user's space active inquiry, and operation characteristic can be improved Efficiency of transmission.

Step 604, data packet is parsed by user's space, obtains the operation characteristic of background process.

Step 606, operation characteristic is analyzed by user's space, determines have the money of the background process of incidence relation Source limit grade.

After user's space receives the data packet of kernel spacing transmission, data packet can be parsed, obtain answering with foreground With the operation characteristic for each background process for having incidence relation.Mobile terminal can have by user's space pair and foreground application The operation characteristic of each background process of incidence relation is analyzed, and determines the resource constraint grade of each process.

In one embodiment, mobile terminal has each backstage of incidence relation by user's space pair with foreground application The operation characteristic of process is analyzed, can be true if the background process for having incidence relation is not communicated with foreground application The resource constraint grade of the fixed background process not communicated is depth limit rank.Mobile terminal can will not answered with foreground It is added in resource group corresponding with depth limit rank with the background process for having incidence relation communicated, and is configured Resource use priority corresponding with depth limit rank, what is do not communicated with foreground application has the backstage of incidence relation Resource few in mobile terminal can be used in process.When movement terminal detects the backstage for having incidence relation by user's space When process is communicated with foreground application, the resource constraint grade of the background process communicated can be reduced.For example, mobile terminal The resource constraint grade for the background process of incidence relation that can determine that is communicated with foreground application have is common limitation rank, And by and the background process for having incidence relation that communicates of foreground application be added to resource corresponding with commonly limitation rank In group, configuration resource use priority corresponding with common limitation rank.When movement terminal detects tool by user's space When the background process of standby incidence relation terminates the communication with foreground application, the resource constraint for terminating the background process of communication can be improved Grade.For example, mobile terminal can determine the resource constraint for the background process for having incidence relation for terminating to communicate with foreground application Grade is depth limit rank etc..

In the present embodiment, the operation for the background process for having incidence relation with foreground application can be acquired by kernel spacing Feature, and the operation characteristic of acquisition is transmitted to user's space and is analyzed, it is possible to provide more lines for determining resource constraint grade Rope foundation can make the resource constraint level adjustment for having the background process of incidence relation with foreground application more accurate, improve money Source control effect and system performance.

In one embodiment, above- mentioned information processing method, further includes: when meeting preset condition, by the backstage of defrosting Process, which re-starts, to be freezed, wherein preset condition includes that the background process to thaw is presetting no and foreground in first time period Entering thawed state using the background process for being communicated, being thawed terminates more than default second time period, foreground application on foreground One of operating status or a variety of.

Backstage after mobile terminal pair thaws with each background process that foreground application has incidence relation, after defrosting The resources such as CPU, memory, I/O and the network of mobile terminal can be used in process, can operate normally and execute task dispatching.It is pre- when meeting If when condition, mobile terminal, which can re-start defrosting with background process that foreground application has incidence relation, to be freezed.It is optional Ground, preset condition may include that the background process to thaw is not communicated with foreground application in default first time period, thawed Background process to enter thawed state be more than that default second time period, foreground application terminate in one of the operating status on foreground Or it is a variety of.First time period and second time period can be set according to actual needs, for example first time period is 10 minutes, the Two periods were 30 minutes etc., but not limited to this.Foreground application terminates to can be foreground application in the past in the operating status on foreground Platform switches to running background, and it is out of service etc. to be also possible to foreground application.It is to be appreciated that preset condition is also possible to other Part is not limited in above-mentioned several.Optionally, mobile terminal defrosting and foreground application can be had the backstage of incidence relation into Journey is added in resource group corresponding with rank is freezed, and configures resource use priority corresponding with the resource group, weight Newly freeze the background process.

In the present embodiment, when meeting preset condition, defrosting can be had into incidence relation with foreground application again Background process is freezed, after process being prevented to be waken up for a long time without freezing the case where, reduce system power dissipation.

As shown in fig. 7, in one embodiment, above- mentioned information processing method is further comprising the steps of:

Step 702, termination signal is sent by user's space.

When mobile terminal needs to terminate the process that some is currently running, termination signal can be sent by user's space, it should Termination signal can be used for terminating the operation of process, keep process out of service and the system resources such as the CPU of release busy, memory.

Step 704, termination signal is intercepted and captured, if the target process of termination signal is in frozen state, thaw target process And each thread under target process including.

Mobile terminal can intercept and capture the termination signal of user's space transmission, and judge whether the target process of the termination signal is located In frozen state.If target process is not at frozen state, termination signal directly can be sent to target process by mobile terminal, Target process can respond the termination signal, terminate the operation of target process.If dbjective state is in frozen state, due to Process in frozen state can not normally receive the signal of other processes transmission, therefore will not normally be rung to termination signal It answers.And in traditional mode, two sets of different codes are usually write, are respectively used to terminate the process of frozen state and non-jelly The process of knot state, exploitation and maintenance to system cause biggish obstacle.After mobile terminal intercepts termination signal, if the end The target process of stop signal is in frozen state, then first can send defrosting signal to target process, to target process and target into The each thread for including under journey thaws.Thread is also referred to as Lightweight Process (LightweightProcess, LWP), Be program execute stream minimum unit, thread is an entity in process, be independently is dispatched and assigned by system substantially singly Position.All threads for including under defrosting target process and target process, can prevent zombie process, cause the wave of system resource Take, wherein zombie process refers to although process has logged out, but also remains some move back in system process table for it The information to do well occupies process list item.

Step 706, setting target process be can not frozen state, and termination signal is sent to target process, terminates letter Number for terminating target process.

After each thread for including under mobile terminal defrosting target process and target process, settable target process is can not Frozen state, can not frozen state refer to again freezing target process.Mobile terminal can send out termination signal Give target process, due to target process be now in can not frozen state, then normally termination signal can be responded, terminate The operation of target process keeps target process out of service and the system resources such as the CPU of release busy, memory.

In the present embodiment, the process in frozen state can be terminated safely, be not in such as the case where zombie process.This Outside, user's space terminates the process of frozen state and non-frozen state, unified termination signal can be transmitted, without writing Two sets of different codes, can reduce system development and maintenance cost.
