具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。举例来说，在不脱离本申请的范围的情况下，可以将第一资源组称为第二资源组，且类似地，可将第二资源组称为第一资源组。第一资源组和第二资源组两者都是资源组，但其不是同一资源组。
图1为一个实施例中移动终端的框图。如图1所示，该移动终端包括通过系统总线连接的处理器、存储器、显示屏和输入装置。其中，存储器可包括非易失性存储介质及处理器。移动终端的非易失性存储介质存储有操作系统及计算机程序，该计算机程序被处理器执行时以实现本申请实施例中提供的一种信息处理方法。该处理器用于提供计算和控制能力，支撑整个移动终端的运行。移动终端中的内存储器为非易失性存储介质中的计算机程序的运行提供环境。移动终端的显示屏可以是液晶显示屏或者电子墨水显示屏等，输入装置可以是显示屏上覆盖的触摸层，也可以是移动终端外壳上设置的按键、轨迹球或触控板，也可以是外接的键盘、触控板或鼠标等。该移动终端可以是手机、平板电脑或者个人数字助理或穿戴式设备等。本领域技术人员可以理解，图1中示出的结构，仅仅是与本申请方案相关的部分结构的框图，并不构成对本申请方案所应用于其上的移动终端的限定，具体的移动终端可以包括比图中所示更多或更少的部件，或者组合某些部件，或者具有不同的部件布置。
图2为一个实施例中信息处理方法的系统架构图。如图2所示，该系统架构中包括JAVA空间层210、本地框架层220以及内核(Kernel)空间层230。JAVA空间层210上可包含冻结管理模块212，移动终端可通过该冻结管理模块212来实现对运行的各个应用的冻结策略，对后台耗电较多或是抢占大量系统资源的相关应用进行冻结操作。本地框架层220中包含资源优先级和限制管理器222和平台冻结管理器224。移动终端可通过资源优先级和限制管理器222实时维护不同的应用处于不同的资源使用优先级和不同的资源组别中，并根据上层的需求来调整应用程序的资源组别从而达到优化性能，节省功耗的作用。移动终端可通过平台冻结管理器224将后台可以冻结的应用按照进入冻结时间的长短，分配到对应预设的不同层次的冻结层。可选地，该冻结层可包括三个，分别是：CPU限制睡眠模式、CPU冻结睡眠模式、进程深度冻结模式。其中，CPU限制睡眠模式是指对相关进程所占用的CPU资源进行限制，使相关进程占用较少的CPU资源，将空余的CPU资源向其它未被冻结的进程倾斜，限制了对CPU资源的占用，也相应限制了进程对网络资源以及I/O接口资源的占用；CPU冻结睡眠模式是指禁止相关进程使用CPU，而保留对内存的占用，当禁止使用CPU资源时，相应的网络资源以及I/O接口资源也被禁止使用；进程深度冻结模式是指除禁止使用CPU资源之外，进一步对相关进程所占用的内存资源进行回收，回收的内存可供其它进程使用。可选地，本地框架层220还可包括接口模块，该接口模块包含开发给上层的binder接口，上层的框架或者应用通过提供的binder接口来发送资源限制或者冻结的指令给资源优先级和限制管理器222和平台冻结管理器224。
内核空间层230中可包括UID管理模块231、Cgroup模块233、Binder管控模块235、进程内存回收模块237以及冻结超时退出模块239。其中，UID管理模块231用于实现基于应用的用户身份标识(User Identifier，UID)来管理第三方应用的资源或进行冻结。相比较于基于进程身份标识(Process Identifier，PID)来进行进程管控，通过UID更便于统一管理一个用户的应用的资源。Cgroup模块233用于提供一套完善的CPU、CPUSET、内存(memory)、输入/输出(input/output，I/O)和Net相关的资源限制机制。Binder管控模块235用于实现后台binder通信的优先级的控制。进程内存回收模块237用于实现进程深度冻结模式，这样能当某个第三方应用长期处于冻结状态的时候，会主要释放掉进程的文件区，从而达到节省内存的模块，也加快该应用在下次启动时的速度。冻结超时退出模块239可用于解决出现冻结超时场景产生的异常。通过上述的系统架构，可实现本申请各个实施例中的信息处理方法。

可选地，移动终端可通过活动管理器对正在运行的应用程序进行监听，获取各个正在运行的应用程序的运行状态。在一个实施例中，移动终端可每隔一段时间通过活动管理器的RunningAppProcessInfo类获取正在运行的应用列表，该应用列表中可记录有移动终端当前运行的各个应用的应用标识，其中，应用标识可以由数字、字母及符号等中的一种或多种组成。移动终端可将本次获取的应用列表中的应用标识与上一次获取的应用列表中的应用标识进行比对。当应用的应用标识仅存在于本次获取的应用列表中，不存在于上一次获取的应用列表时，则可确定该应用为新启动的应用。移动终端可获取新启动的应用，并判断该新启动的应用是在前台运行还是后台运行，当该新启动的应用在前台运行时，则可 确定该应用为启动的前台运用。
操作320，当运行时间达到预设时间阈值时，则获取与前台应用具备关联关系的后台进程。
进程(Process)是计算机中的程序关于某数据集合上的一次运行活动，是系统进行资源分配和调度的基本单位，是操作系统结构的基础。移动终端上通常可运行有多个进程，不同的进程可用于分别执行不同的任务。当移动终端监听到前台应用启动时，可记录该前台应用启动后在前台运行的时间。当该前台应用启动后在前台运行的时间达到预设时间阈值时，移动终端可获取当前在后台运行的与前台应用具备关联关系的后台进程。可选地，移动终端可通过活动管理器获取当前在后台运行的各个进程，并根据前台应用的应用标识在当前在后台运行的各个进程中查询与前台应用具备关联关系的后台进程。移动终端可预先存储应用及进程的关联关系，当监听到前台应用启动，且该前台应用启动后在前台的运行时间达到预设时间阈值时，可根据前台应用的应用标识获取与该前台应用具备关联关系的后台进程。
可选地，与前台应用具备关联关系的后台进程可以是与前台应用具备通信机制的后台进程、与前台应用具备调用关系的后台进程，或是与前台应用属于同一系发布商的后台进程等，但不限于此。通信机制指的是在不同的进程和/或应用之间进行传播或交换信息。可选地，通信机制可包括socket、binder、共享内存等，其中，网络上的两个程序通过一个双向的通信连接实现数据的交换，这个连接的一端称为一个socket；binder是一种进程间通信机制，提供远程过程调用功能；共享内存就是允许两个不相关的进程访问同一个逻辑内存，共享内存是在两个正在运行的进程之间共享和传递数据的一种非常有效的方式，不同进程之间共享的内存通常安排为同一段物理内存。调用关系指的是前台应用可调用后台进程执行相应的任务，比如调用后台进程存储的登录信息进行登录操作，其中，登录信息指的是可用于登录的账户信息、密码等信息，或是调用后台进程进行定位等，但不限于此。与前台应用属于同一系发布商的后台进程可携带有与前台应用相同的发布标签，该发布标签可用于标识发布应用程序的发布商。
操作330，确定与前台应用具备关联关系的后台进程的状态。
移动终端可获取生成的与前台应用具备关联关系的各个后台进程的状态，可选地，后台进程的状态可包括但不限于冻结状态及解冻状态等。冻结状态指的是后台进程无法使用CPU、/O及网络等资源，处于无法继续运行的状态，但是该后台进程依然会占据内存资源、硬盘资源等；解冻状态指的是后台进程可使用CPU、I/O、内存及网络等系统资源，处于可运行执行任务的状态。
在一个实施例中，移动终端可获取与前台应用具备关联关系的处于冻结状态的后台进程。可选地，移动终端可获取与前台应用具备关联关系的各个后台进程的状态标签，不同的状态可用不同的状态标签进行表示，例如，冻结状态对应的状态标签为0，解冻状态对应的状态标签为1等，但不限于此。移动终端可根据与前台应用具备关联关系的各个后台进程的状态标签获取处于冻结状态的后台进程。
可选地，移动终端也可分别向与前台应用具备关联关系的各个后台进程发送通信信号，并检测是否在预定时间段内接收到响应信号。当没有在预定时间段内接收到进程返回的响应信号时，则可确定没有发送响应信号的后台进程的状态为冻结状态。可以理解地，也可采用其他方式获取与前台应用具备关联关系的处于冻结状态的后台进程，并不仅限于上述几种方式。
操作340，当后台进程的状态为冻结状态时，则对后台进程进行解冻。
移动终端获取与前台应用具备关联关系的处于冻结状态的后台进程后，可将该处于冻结状态的后台进程进行解冻。移动终端可向与前台应用具备关联关系的处于冻结状态的后台进程发送解冻信息，通过解冻信号使后台进程进入解冻状态，可以使用CPU、I/O、内 存及网络等系统资源，可正常进行运行并执行任务。当前台应用在运行中需要使用具备关联关系的后台进程时，无需重新对后台进程进行解冻，可提高响应速率。此外，仅解冻与前台应用具备关联关系的后台进程，而不解调冻后台进程所属的整个应用，可以减少系统消耗。
可选地，移动终端可获取与前台应用具备通信机制的后台进程，并确定与前台应用具备通信机制的后台进程的状态。移动终端可对处于冻结状态的与前台应用具备通信机制的后台进程进行解冻，解冻后的后台进程可正常与前台应用进行通信。可以保证前台应用与后台进程的正常通信，提高系统响应速率。
在本实施例中，当监听到前台应用启动时，记录前台应用启动后在前台的运行时间，当运行时间达到预设时间阈值时，获取与前台应用具备关联关系的后台进程，并对处于冻结状态的具备关联关系的后台进程进行解冻，可以对与前台应用具备关联关系的后台进程进行解冻，减少前台应用在运行中需要使用具备关联关系的后台进程再进行解冻的等待时间，加快系统响应速率。
如图4所示，在一个实施例中，在操作对后台进程进行解冻之后，还包括以下操作：
操作402，获取与前台应用具备关联关系的后台进程的运行特征。
移动终端对与前台应用具备关联关系的处于冻结状态的后台进程进行解冻后，可获取与前台应用具备关联关系的各个后台进程的运行特征。其中，运行特征可包括但不限于后台进程当前执行的任务、与其他进程和/或应用等的通信事件、当前占用的资源类型及比例等。
操作404，根据运行特征确定具备关联关系的后台进程的资源限制等级。
移动终端可对与前台应用具备关联关系的各个后台进程的运行特征进行分析，并根据运行特征确定对应后台进程的资源限制等级。可选地，移动终端可根据实际需求设定不同的资源限制等级，资源限制等级可用于表示使用资源被限制的程度，资源限制等级越高，受限制的程度可越大。受限制的资源可包括但不限于CPU资源、内存资源、I/O资源、网络资源等。不同的资源限制等级可对应不同的资源使用优先级，资源限制等级越高，对应的资源使用优先级可越小，资源限制等级越低，对应的资源使用优先级可越大。
在一个实施例中，移动终端设定的资源限制等级可包括无限制级别、普通限制级别、深度限制级别及冻结级别等。无限制级别可指的是进程使用的资源不受限制。普通限制级别可指的是进程可使用较少的资源，比如最多仅可使用50％的资源等，但不限于此。深度限制级别可指的是进程可使用极少的资源，比如最多仅可使用20％的资源等，但不限于此。冻结级别指的是进程无法使用任何的资源，停止进程的一切行为。比如，前台应用可对应无限制级别，前台应用使用的资源不受限制；当与前台应用具备关联关系的后台进程没有与前台应用进行通信时，则可对应深度限制级别，可使用极少的资源等，但不限于此。
操作406，将具备关联关系的后台进程分配到与资源限制等级对应的资源组别中，并配置与资源限制等级对应的资源使用优先级。
移动终端确定与前台应用具备关联关系的各个后台进程的资源限制等级后，可将与前台应用具备关联关系的各个后台进程分配到与确定的资源限制等级对应的资源组别中，并配置与资源限制等级对应的资源使用优先级。可选地，移动终端可基于内核Cgroup(control group)机制划分不同的资源组别，并可采用文件节点写配置的方式设置各个资源组别的资源使用优先级，对被分配到各个资源组别中的进程使用资源的时间或比例等进行管理，其中，Cgroup是内核中提供的一种可以限制、记录、隔离进程所使用的物理资源(比如：CPU、内存、I/O等资源)的机制。移动终端可加载Cgroup的配置文件，配置文件中可记录有划分的资源组别、各个资源组别的资源使用优先级及与资源使用优先级对应的资源调度策略。资源调度策略可包括但不限于被分配到资源组别中的进程使用资源的时间、占用资源比例、使用的资源标识等。例如，可配置普通限制级别对应的资源组别 的进程在1分钟内可使用30秒的CPU资源，且普通限制级别对应的资源组别的进程仅能使用编号为X的CPU资源等，但不限于此。当需要添加新的资源组别，或是修改资源组别的资源使用优先级及资源调度策略，可通过修改Cgroup的配置文件来实现。
移动终端将与前台应用具备关联关系的各个后台进程分配到与资源限制等级对应的资源组别中，并配置与资源限制等级对应的资源使用优先级后，与前台应用具备关联关系的后台进程可按照该资源组别对应的资源调度策略使用CPU、内存、I/O及网络等资源。在一个实施例中，移动终端可每隔一定时间段获取与前台应用具备关联关系的各个后台进程的运行特征，并根据运行特征确定具备关联关系的后台进程的资源限制等级。与前台应用具备关联关系的后台进程的资源限制等级可随着运行特征的变化而进行改变。比如，后台进程结束与前台应用的通信后，可提高该后台进程的资源限制等级等，但不限于此。
图5为一个实施例中资源组别的示意图。如图5所示，移动终端中可设定有四个不同的资源限制等级，并划分有四个资源组别，其中，第一资源组别对应无限制级别，第二资源组别对应普通限制级别，第三资源组别对应深度限制级别，第四资源组别对应冻结级别。四个资源组别可分别对应不同的资源使用优先级，第一资源组别的资源使用优先级可高于第二资源组别，第二资源组别的资源使用优先级可高于第三资源组别，第三资源组别的资源使用优先级可高于第四资源组别。无限制级别的第一资源组别不限制进程使用的CPU、内存、I/O及网络等资源。普通限制级别的第二资源组别限制进程可使用较少的CPU、内存、I/O及网络等资源。深度限制级别的第三资源组别限制进程可使用极少的CPU、内存、I/O及网络等资源。冻结级别的第四资源组别限制进程不可使用CPU、内存、I/O及网络等资源。移动终端根据与前台应用具备关联关系的各个后台进程的运行特征确定资源限制等级，并将与前台应用具备关联关系的各个后台进程添加到相应的资源组别中，配置与资源组别对应的资源使用优先级，对与前台应用具备关联关系的各个后台进程使用的资源进行管理。
在本实施例中，可根据与前台应用具备关联关系的后台进程的运行特征确定资源限制等级，对与前台应用具备关联关系的后台进程动态实现不同等级的资源限制，在对与前台应用具备关联关系的后台进程进行解冻，提高系统响应速率的同时，减少具备关联关系的后台进程抢占前台应用的资源，优化系统性能，节省功耗。
如图6所示，在一个实施例中，上述信息处理方法，还包括以下操作：
操作602，通过内核空间采集与前台应用具备关联关系的后台进程的运行特征，并将运行特征打包成数据包传送给用户空间。
移动终端的虚拟空间中可包括有内核空间及用户空间，内核空间可用于存放内核的代码和数据，用户空间可用于存放应用程序的代码和数据。内核空间拥有较高的特权级别，在内核空间中运行的进程可拥有访问移动终端的所有硬件的权限，用户空间的权限则较低，在用户空间中运行的进程仅可使用系统的部分资源。
移动终端可通过内核空间采集与前台应用具备关联关系的各个后台进程的事件数据，事件数据可包括但不限于事件类型、事件时间、事件内容、事件所属的进程标识等。事件类型可包括但不限于通信事件、创建事件、退出事件、更改标识事件、任务事件等。通信事件可指的是进程与其他应用和/或进程的通信事件，可包括binder通信事件及socket通信事件等。创建事件可指的是进程等被创建的事件。退出事件指的是进程退出的事件。更改标识事件可指的是进程更改自身的标识等。任务事件可指的是进程执行的任务等。

操作604，通过用户空间解析数据包，得到后台进程的运行特征。
操作606，通过用户空间对运行特征进行分析，确定具备关联关系的后台进程的资源限制等级。
用户空间接收到内核空间传输的数据包后，可对数据包进行解析，得到与前台应用具备关联关系的各个后台进程的运行特征。移动终端可通过用户空间对与前台应用具备关联关系的各个后台进程的运行特征进行分析，确定各个进程的资源限制等级。
在一个实施例中，移动终端通过用户空间对与前台应用具备关联关系的各个后台进程的运行特征进行分析，当具备关联关系的后台进程没有与前台应用进行通信时，则可确定没有进行通信的后台进程的资源限制等级为深度限制级别。移动终端可将没有与前台应用进行通信的具备关联关系的后台进程添加到与深度限制级别对应的资源组别中，并配置与深度限制级别对应的资源使用优先级，没有与前台应用进行通信的具备关联关系的后台进程可使用移动终端中极少的资源。当移运终端通过用户空间检测到具备关联关系的后台进程与前台应用进行通信时，可降低进行通信的后台进程的资源限制等级。例如，移动终端可确定与前台应用进行通信的具备关联关系的后台进程的资源限制等级为普通限制级别，并将与前台应用进行通信的具备关联关系的后台进程添加到与普通限制级别对应的资源组别中，配置与普通限制级别对应的资源使用优先级。当移运终端通过用户空间检测到具备关联关系的后台进程结束与前台应用的通信时，可提高结束通信的后台进程的资源限制等级。例如，移动终端可确定与前台应用结束通信的具备关联关系的后台进程的资源限制等级为深度限制级别等。
在本实施例中，可通过内核空间采集与前台应用具备关联关系的后台进程的运行特征，并将采集的运行特征传输至用户空间进行分析，可提供更多确定资源限制等级的线索依据，可使与前台应用具备关联关系的后台进程的资源限制等级调整更加准确，提高资源管理效果及系统性能。
在一个实施例中，上述信息处理方法，还包括：当满足预设条件时，将解冻的后台进程重新进行冻结，其中，预设条件包括解冻的后台进程在预设第一时间段内没有与前台应用进行通信、解冻的后台进程进入解冻状态超过预设第二时间段、前台应用结束在前台的运行状态中的一种或多种。
移动终端对与前台应用具备关联关系的各个后台进程进行解冻后，解冻后的后台进程可使用移动终端的CPU、内存、I/O及网络等资源，可正常运行并执行任务等。当满足预设条件时，移动终端可将解冻的与前台应用具备关联关系的后台进程重新进行冻结。可选地，预设条件可包括解冻的后台进程在预设第一时间段内没有与前台应用进行通信、解冻的后台进程进入解冻状态超过预设第二时间段、前台应用结束在前台的运行状态中的一种或多种。第一时间段及第二时间段可根据实际需求进行设定，比如第一时间段为10分钟，第二时间段为30分钟等，但不限于此。前台应用结束在前台的运行状态可以是前台应用从前台切换至后台运行，也可以是前台应用退出运行等。可以理解地，预设条件也可以是其他条件，并不仅限于上述几种。可选地，移动终端可将解冻的与前台应用具备关联关系的后台进程添加到与冻结级别对应的资源组别中，并配置与该资源组别对应的资源使用优先级，重新冻结该后台进程。
在本实施例中，当满足预设条件时，可重新将解冻的与前台应用具备关联关系的后台进程进行冻结，可以防止进程被唤醒后长期不进行冻结的情况，降低系统功耗。
如图7所示，在一个实施例中，上述信息处理方法，还包括以下操作：
操作702，通过用户空间发送终止信号。
当移动终端需要终止某个正在运行的进程时，可通过用户空间发送终止信号，该终止 信号可用于终止进程的运行，使进程退出运行并释放占用的CPU、内存等系统资源。
操作704，截获终止信号，当终止信号的目标进程处于冻结状态时，则解冻目标进程及目标进程下包含的各个线程。
移动终端可截获用户空间发送的终止信号，并判断该终止信号的目标进程是否处于冻结状态。当目标进程不处于冻结状态时，则移动终端可直接将终止信号发送给目标进程，目标进程可对该终止信号进行响应，终止目标进程的运行。当目标状态处于冻结状态时，由于处于冻结状态的进程无法正常接收其他进程发送的信号，因此不会对终止信号进行正常响应。而在传统的方式中，通常要编写两套不同的代码，分别用于终止冻结状态的进程及非冻结状态的进程，给系统的开发及维护造成了较大的障碍。移动终端截取终止信号后，当该终止信号的目标进程处于冻结状态时，则可先向目标进程发送解冻信号，对目标进程及目标进程下包含的各个线程进行解冻。线程也可被称为轻量级进程(Lightweight Process，LWP)，是程序执行流的最小单元，线程是进程中的一个实体，是被系统独立调度和分派的基本单位。解冻目标进程及目标进程下包含的所有线程，可防止出现僵尸进程，造成系统资源的浪费，其中，僵尸进程指的是进程虽然已经退出了，但是在系统进程表中还为它保留了一些退出状态的信息，占用进程表项。
操作706，设置目标进程为不可冻结状态，并将终止信号发送给目标进程，终止信号用于终止目标进程。
移动终端解冻目标进程及目标进程下包含的各个线程后，可设置目标进程为不可冻结状态，不可冻结状态指的是无法重新对目标进程进行冻结。移动终端可将终止信号发送给目标进程，由于目标进程此时处于不可冻结状态，则可正常对终止信号进行响应，终止目标进程的运行，使目标进程退出运行并释放占用的CPU、内存等系统资源。
在本实施例中，可安全终止处于冻结状态的进程，不会出现如僵尸进程的情况。此外，用户空间对于冻结状态和非冻结状态的进程终止，均可发送统一的终止信号，无需编写两套不同的代码，可减少系统开发和维护成本。
