Description

一种终端后台应用程序的管理方法及装置 技术领域
本发明涉及终端技术领域，尤其涉及一种终端后台应用程序的管理方法及装置。
背景技术
当前随着手机或者平板电脑等终端的软硬件技术的发展，现有的终端操作系统中包含越来越多具备多任务运行能力的操作系统。操作系统的多任务运行功能可支持多个应用程序在同一时间处于启动状态，处于启动状态的应用程序可在操作系统的前台和后台之间切换运行。操作系统同时支撑多个应用程序的运行的操作过程中，每个应用程序被称为一个任务，在后台运行的任务会占用终端的处理器资源。若与前台任务争抢处理器资源的后台任务较多，则将导致操作系统对前台任务的响应不及时，使得前台应用程序出现卡顿丢帧等问题，影响了应用程序的用户体验。
现有技术将前台任务和后台任务分为前台分组和后台分组，并为不同的分组分配不同的处理器资源，通过这种方式来缓解前台任务和后台任务争抢处理器资源的问题。然而，现有技术将后台任务全部放入后台分组，后台分组只分配少部分处理器资源，很大程度上限制了后台任务对处理器资源的占用。此时，若后台任务中包含用户可明显感知的任务，例如音乐播放等，后台任务可用的处理器资源较少则将导致音乐播放的后台任务运行不顺畅，比如声音卡顿等。用户可明显感知到后台任务运行不顺畅，降低了终端的用户体验，适用性低。

其中，所述第一处理资源大于预先分配给所述终端操作系统后台中的应用程序的第二处理资源。
本申请可将终端操作系统后台中运行的各个应用程序中处于预设运行状态的应用程序确定为目标应用程序，进而可为目标应用程序分配更多的处理资源。通过为后台应用程序中的目标应用程序分配更多的处理资源，使得目标应用程序的可占用资源多于原来分配给后台所有应用程序共享的处理资源，可保障目标应用程序的运行更顺畅，增强应用程序的运行状态的可控性，提高终端的用户体验。
结合第一方面，在第一种可能的实现方式中，所述为所述第一目标应用程序分配终端的第一处理资源包括：

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供的终端后台应用程序的管理方法主要应用于终端设备，该终端设备也可称之为用户设备英文：(User Equipment，UE)、移动台(英文：Mobile Station，MS)、移动终端(英文：Mobile Terminal)等。可选的，该终端设备(以下简称终端)可以具备经无线接入网(英文：Radio Access Network，RAN)与一个或多个核心网进行通信的能力。例如，终端可以是移动电话(或称为“蜂窝”电话)、或具有移动性质的计算机等。例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。应理解的是，除了终端设备以外，本发明实施例提供的终端后台应用程序的管理方法也可以应用于其他类型的计算机系统。
请参考图1，为本发明实施例提供的终端设备的结构示意图。如图1所示，终端设备100包括存储器180、处理器150以及显示设备140。存储器180存储计算机程序(或称程序代码)，该计算机程序包括操作系统程序182和应用程序181等。处理器150用于读取存 储器180中的计算机程序，然后执行计算机程序定义的方法，例如处理器150读取操作系统程序182从而在该终端设备100上运行操作系统以及实现操作系统的各种功能，或读取一种或多种应用程序181，从而在该终端设备上运行应用。
处理器150可以包括一个或多个处理器，例如，处理器150可以包括一个或多个中央处理器，或者包括一个或者多个中央处理器和一个或者多个应用处理器。当处理器150包括多个处理器时，这多个处理器可以集成在同一块芯片上，也可以各自为独立的芯片。一个处理器可以包括一个或多个处理器核(或称处理核)，以下实施例均以多核为例来介绍，但是本发明实施例提供的终端后台应用程序的管理方法也可以应用于单核处理器，利用单核处理器的分时工作原理执行多个应用程序的并行运行。
另外，存储器180还存储有除计算机程序之外的其他数据183，其他数据183可包括操作系统182或应用程序181被运行后产生的数据，该数据包括系统数据(例如操作系统的配置参数)和用户数据，例如用户下载的一首网络歌曲就是典型的用户数据，下载网络歌曲的应用程序也是本发明实施例提供的方法的管理的对象之一。
存储器180一般包括内存和外存。内存可以为随机存储器(RAM)，只读存储器(ROM)，以及高速缓存(CACHE)等。外存可以为硬盘、光盘、USB盘、软盘或磁带机等。计算机程序通常被存储在外存上，处理器在执行处理前会将计算机程序从外存加载到内存。
操作系统程序182中包含了可实现本发明实施例提供的终端后台应用程序的管理方法的计算机程序，从而使得处理器150读取到该操作系统程序182并运行该操作系统后，该操作系统可具备本发明实施例提供的后台应用程序的管理功能。
终端设备100还可以包括输入设备130，用于接收输入的数字信息、字符信息或接触式触摸操作/非接触式手势，以及产生与终端设备100的用户设置以及功能控制有关的信号输入等。具体地，本发明实施例中，该输入设备130可以包括触控面板131。触控面板131，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板131上或在触控面板131的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板131可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给该处理器150，并能接收处理器150发来的命令并加以执行。例如，用户在触控面板131上用手指双击一个应用程序的图标，触摸检测装置检测到此次双击带来的这个信号，然后将该信号传送给触摸控制器，触摸控制器再将这个信号转换成坐标发送给处理器150，处理器150根据该坐标和该信号的类型(如双击)执行启动该应用程序等操作，最后将该应用程序的操作界面显示在显示面板141上，从而实现“打开”应用程序。
触控面板131可以采用电阻式、电容式、红外线以及表面声波等多种类型实现。除了触控面板131，输入设备130还可以包括其他输入设备132，其他输入设备132可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆等中的一种或多种。
终端设备100还可以包括显示设备140，显示设备140，包括显示面板141，用于显示由用户输入的信息或提供给用户的信息以及终端设备100的各种菜单界面等，在本发明实 施例中主要用于显示应用程序的用户操作界面等信息。该显示设备140可包括显示面板141，可选的，可以采用液晶显示器(英文：Liquid Crystal Display，LED)或有机发光二极管(英文：Organic Light-Emitting Diode，OLED)等形式来配置显示面板141。在其他一些实施例中，触控面板131可覆盖显示面板141上，形成触摸显示屏。
除以上之外，终端设备100还可以包括用于给其他模块供电的电源190以及用于拍摄照片或视频的摄像头160。终端设备100还可以包括一个或多个传感器120，例如重力传感器、加速度传感器、光传感器等。终端设备100还可以包括无线射频(英文：Radio Frequency,RF)电路110，用于与无线网络设备进行网络通信，还可以包括WiFi模块170，用于与其他设备进行WiFi通信等。
下面的实施例将以终端为执行主体对本发明实施例提供的终端后台应用程序的管理方法及装置进行描述。本发明实施例提供的管理方法可以实现在图1所示的操作系统程序182中。
具体实现中，终端启动应用程序(英文：application，APP)1并在终端的操作系统的前台执行完某个任务之后，若终端启动APP2，则APP1将切换至终端的操作系统的后台(下面简称后台)。APP1切换至后台之后还处于启动状态，还可继续在后台运行相关任务，此时APP1运行任务还会占用处理器资源。APP1和APP2的运行过程中会存在争抢处理器资源的现象，若APP1占用的处理器资源较多则将导致APP2在前台运行出现卡顿等现象。其中，上述处理器资源具体可为中央处理器(英文：Central Process Unit，CPU)资源或者应用处理器(英文：Application Processor，AP)资源等。上述应用处理器资源具体可为arm公司生产是一款精简指令集(英文：Reduced Instruction Set Computer，RISC)微处理器(英文：Advanced RISC Machines，ARM)，也可为其他应用于手机等终端设备上的处理器。具体可根据实际应用场景需求确定，在此不做限制。下面将以CPU资源为处理器资源为例对本发明实施例提供的终端后台应用程序的管理方法及装置进行说明。
具体实现中，解决前后台任务争抢CPU资源的问题可采用基于控制组(英文：Control Group，CGroup)的前后台控制机制。参见图2，图2是本发明实施例提供的一应用程序管理操作示意图。如图2所示，前后台控制机制通过把前台APP放到前台控制组(英文：Foreground CGroup，FG CGroup)(或称前台分组)，将所有后台APP放到后台控制组(英文：Background CGroup，BG CGroup)(或称后台分组)，并分别为前台控制组和后台控制组分配CPU资源。其中，为前台控制组分配的CPU资源包括终端中包含的所有处理器核(如CPU核或者ARM核，下面以CPU核为例)中的大部分CPU核，如图2中的编号0-7的8个CPU核。其中，上述编号0-7的8个CPU核为终端包含的CPU核。此外，终端将每个CPU核的大部分比例资源分配给前台控制组。例如，将终端中包含的所有CPU核(编号0-7的8个CPU核)分配给前台控制组，即前台控制组可使用所有CPU核上的资源。此外，还可将每个CPU核的可占用资源(例如CPU核的可占用时间)中的95％分配给前台控制组等。具体的，还可为后台控制组还可分为后台控制分组和系统后台控制组，其中，系统后台控制组中包含的APP为终端系统运行必不可少的系统APP或者终端出厂配置的APP等，后台控制分组为后台应用程序中除去系统后台控制组中包含的APP之外的后台APP。上述实现方式为后台控制分组分配较少的CPU资源，比如一个CPU核(编号为3 的CPU核)，为系统后台控制分组分配3个CPU核，如图2中编号0-2的3个CPU核，并且后台控制组中包含的所有APP只能共享该CPU核中的5％的可占用时间等。通过为前台控制组中包含的APP分配更多的资源来保障前台控制组的APP运行顺畅，提高终端的前台APP运行的用户体验。
然而，上述实现方式没有考虑到前后台任务之间可能存在相互依赖的情况，以及后台任务的输出结果对用户体验的影响等现象。具体实现中，某些任务即使处于后台，其输出结果也是用户可实时感知的，包括语音播放等。若处于后台的任务(假设为任务A)的输出结果是用户可实时感知的，系统则需要保障任务A的运行顺畅。在该场景中，上述实现方式中后台任务所拥有的CPU资源较少，难以保障任务A的运行顺畅。若前台任务的执行需要依赖后台任务的运行结果或者后台任务持有前台任务所需的资源，即前台任务和后台任务之间存在关联，则后台任务的运行不顺畅也将导致前台任务的执行受到阻碍，前台任务可能出现卡顿丢帧的现象。
为了上述现有实现方式中存在的CPU资源分配形式单一，操作不灵活以及终端的APP管理方法的适用性差等问题，本发明实施例提供了一种终端后台应用程序的管理方法及装置，可增强终端后台应用程序的运行状态的可控性，提高终端后台应用程序的管理的适用性，增强终端的用户体验。
参见图3，是本发明实施例提供的终端后台应用程序的管理方法的流程示意图。本发明实施例提供的管理方法，包括步骤：
S201，检测终端操作系统后台中运行的应用程序中各个应用程序的运行状态。
在一些可行的实施方式中，本发明实施例可根据后台APP的运行状态对后台APP中的关键APP进行区别化管理，以保证关键APP的运行顺畅，进而可提高终端的用户体验。具体实现中，终端可对后台中运行的应用程序进行检测，确定各个应用程序的运行状态。其中，上述应用程序的运行状态包括应用程序的输出结果对前台应用程序的运行是否造成影响，即后台应用程序中是否存在与前台应用程序关联的应用程序。此外，上述应用程序的运行状态还可包括应用程序的输出结果用户是否可以明显感知，即应用程序是否为需要保障运行顺畅的应用程序等。具体的，终端可在某个APP(例如上述APP1)切换到后台时检测APP1与前台APP(例如上述APP2)的运行状态，判断上述APP1与APP2是否存在关联关系。或者，终端可将APP1与预设的APP类别进行比对，判断上述APP1是否为需要保障运行顺畅的APP。进一步的，终端也可使用周期性(例如10秒一个周期等)检测的方式，在指定时间对系统后台中运行的所有应用程序中每个应用程序的运行状态进行检测，以确定后台应用程序中是否存在与前台应用程序关联的目标应用程序或者需要保障运行顺畅的目标应用程序等。其中，上述与前台应用程序关联的目标应用程序或者需要保障运行顺畅的目标应用程序则为本发明实施例中描述的关键应用程序。
S202，从所述各个应用程序中选取第一目标应用程序。
在一些可行的实施方式中，终端可通过对后台应用程序的检测获取后台应用程序中的目标应用程序(即第一目标应用程序)。其中，上述第一目标应用程序为运行状态为预设运行状态的应用程序。具体的，第一目标应用程序可包括上述与前台应用程序关联的目标应用程序或者需要保障运行顺畅的目标应用程序等。其中，上述预设运行状态可包括语音播 放状态、文件传输状态、使用传感器状态、视频通话状态以及语音通话状态等，处于上述预设运行状态的应用程序可设定为需要保障运行顺畅的目标应用程序。上述预设运行状态也可为与前台应用程序关联的状态，处于上述与前台应用程序关联的状态的应用程序可设定为与前台关联的目标应用程序。下面将结合步骤S203对处于预设运行状态的应用程序进行CPU资源分配等区别性管理。
S203，为所述第一目标应用程序分配终端的第一处理资源，并将所述第一目标应用程序设置在所述第一处理资源上运行。
在一些可行的实施方式中，终端的操作系统前台运行的应用程序(例如上述APP2)可设定为第二目标应用程序，即上述前台控制组中包含的应用程序可设定为第二目标应用程序。上述后台中运行的所有应用程序可为上述后台控制组中包含的应用程序，即，上述第一目标应用程序可为现有技术中分在后台控制组中的一个或者多个应用程序。本发明实施例提供的前台控制组可占用终端的一部分资源，比如上述终端的所有CPU核，以及每个CPU核的95％的可占用时长等。本发明实施例提供的后台控制组也可占用终端的一部分资源(设为第二处理资源)，比如上述终端的所有CPU核中的一个以及该CPU核的5％的可占用时长。其中，上述后台控制组所占用的CPU核的另外95％的可占用时长也为上述前台控制组所拥有的资源，也可为本发明实施例提供的关键应用程序所拥有的资源，具体可根据实际应用场景确定，在此不做限制。
在一些可行的实施方式中，终端可将后台APP中处于语音播放状态、文件传输状态、使用传感器状态、视频通话状态或者语音通话状态等运行状态中的APP确定为第一目标APP，以对处于上述运行状态中的第一目标APP进行CPU资源分配，保证上述第一目标APP的运行顺畅。具体实现中，终端可创建一个关键后台控制组(英文：key background CGroup，Kbg CGroup)，将上述第一目标APP放入关键后台控制组(即目标应用程序组)中，并为关键后台控制组分配CPU资源。具体实现中，上述第一目标APP可为处于上述语音播放状态、文件传输状态、使用传感器状态、视频通话状态或者语音通话状态等运行状态的一个或者多个APP，具体可根据各个APP的具体工作状态确定，在此不做限制。相应的，上述关键后台控制组中可包含一个或者多个APP，并且上述关键后台控制组中包含的APP可为上述第一目标APP。
具体实现中，终端确定了后台APP中包含的第一目标APP之后，则可为第一目标APP分配CPU资源。具体的，终端可根据已分配给前台控制组的CPU资源的情况，以及已分配给后台控制组的CPU资源的情况为关键后台控制组分配终端的第一处理资源(具体可为第一CPU资源)。在本发明实施例中，终端拥有的CPU核可为多个。其中，分配给前台控制组的CPU资源可为终端所拥有的所有CPU核并且每个CPU核的预设比例1(例如95％)的可占用时长等，分配给后台控制组的CPU资源可为终端所拥有的CPU核中的一个(或者多个)并且为每个CPU核的预设比例2(例如5％)的可占用时长等。终端为关键后台控制组分配的第一CPU资源少于前台控制组所拥有的CPU资源，多于后台控制组所拥有的CPU资源。具体实现中，由于前台控制组的APP运行顺畅的保障优先级最高，因此，关键后台控制组所占用的第一CPU资源的分配方式既可保证关键后台控制组的APP运行顺畅，也可避免关键后台控制组的APP与前台控制组的APP抢占资源，影响前台控制组的 APP的运行。需要说明的是，具体实现中，终端也可为关键后台控制组分配与前台控制组相同的CPU资源，具体可根据实际应用场景需求确定，在此不做限制。
例如，若终端为后台控制组分配1个CPU核，终端则可为关键后台控制组分配2个或者3个等多于1个的CPU核。具体实现中，终端还可为系统APP分配CPU资源。如图4，图4是本发明实施例提供的CPU资源的一分配示意图。例如，终端将其系统中包含的APP分为前台控制组、系统后台控制组(其中包含终端的系统APP，例如系统运行必不可少的APP或者终端出厂配置的APP等)、关键后台控制组和后台控制分组等APP分组。若终端中包含编号为0到7的8个CPU核，终端则可将8个CPU核分配给前台控制组，将编号为0到2的3个CPU核分配给系统后台控制组，将编号为1、2和7的3个CPU核分配给关键后台控制组，并将编号为3的1个CPU核分配给后台控制分组。其中，上述CPU核的数量与编号等CPU核的分配方式仅是举例，而非穷举。其中，前台控制组所拥有的CPU核数量最多，系统后台控制组所拥有的CPU核数量少于前台控制组，关键后台控制组所拥有的CPU核数量少于前台控制组，后台控制组所拥有的CPU核数量最少。系统后台控制组与关键后台控制组之间的CPU核的数量大小关系在此不做限制，具体可根据实际应用场景确定。
进一步的，如图4，在一些可行的实施方式中，终端为各个APP控制组分配CPU核资源之后，若各个APP控制组中包含的APP在同一个CPU核上运行，则可进一步为各个APP控制组中包含的APP分配该CPU核的资源。例如，终端可将系统后台控制组中包含的APP记入前台控制组，并为前台控制组和系统后台控制组分配CPU核的预设比例1(例如95％)的可占用时长。终端还可将关键后台控制组合后台控制分组记为后台控制组，并将CPU核的预设比例2(例如5％)的可占用时长分配给关键后台控制组和后台控制分组。其中，后台控制分组中包含的APP为终端后台的所有APP中除去系统后台控制组和关键后台控制组中包含的APP之后的APP。例如，假设终端系统后台的所有APP有5个，其中放入系统后台控制组的APP为2个，放入关键后台控制组的APP为1个，则剩下的2个APP则为后台控制组中包含的APP。
进一步的，在一些可行的实施方式中，若上述选取的第一目标APP为与前台APP(即第二目标APP)关联的APP，则可将上述第一目标APP添加至前台控制组。终端将上述第一目标APP添加至前台控制组之后，上述第一目标APP则可与前台控制组中包含的其他APP共享前台控制组所拥有的CPU资源。其中，第一目标APP与前台控制组中包含的其他APP共享的前台控制组所用的CPU资源包括前台控制组所拥有的CPU核以及每个CPU核的可占用时长等资源，在此不再赘述。由于第一目标APP与前台APP关联，第一目标APP的运行顺畅与否将较大程度地影响着前台APP的运行，因此，第一目标APP运行顺畅的保障优先级应该等于前台APP或者略低于前台APP。终端设置第一目标APP则可与前台控制组中包含的其他APP共享前台控制组所拥有的CPU资源，保障第一目标APP的运行顺畅的同时保障着前台APP的运行顺畅，提高了终端的用户体验。需要说明的是，在一些可行的实施方式中，第一目标APP与前台APP关联时终端也可为第一目标APP单独建立一个分组(如关键后台控制组)，并按照上述关键后台控制组的资源分配方式为第一目标APP分配资源，具体可根据实际应用场景需求确定，在此不做限制。
在一些可行的实施方式中，上述终端的前台APP与后台APP之间的关联关系可通过进程之间的关联关系确定。具体的，终端可在活动管理服务(英文：activity manager service，AMS)中采集系统中运行的各个进程之间的关联关系，并通过系统服务的实时处理子系统对各个进程之间的关联关系进行分析、确定。其中，上述各个进程之间的关联关系可使用getContentProvider，startActivity，bindService、unbindService，startService、stopService等关联关系采集函数来确定，具体可根据实际应用场景确定，在此不做限制。
具体实现中，若上述第一目标APP运行完处于上述预设运行状态的任务，则可将上述第一目标APP放入后台控制组中，以避免占用CPU资源。例如，APP4处于语音通话状态时，可将其放入关键后台控制组，此时，APP4的可占用CPU资源为关键后台控制组所拥有的CPU资源。若APP4语音通话结束，则可将其放入后台控制分组中，此时APP4的可占用CPU资源则为后台控制分组所拥有的CPU资源。
在一些可行的实施方式中，终端还可在系统的各个APP运行过程中，对系统中的异常APP进行检测和管理。具体实现中，终端可以以一定的周期(例如10秒一个周期)检测终端中包含的所有CPU核中每个CPU核的负载状态，以判别终端中是否存在负载异常的CPU核(设为异常CPU核)。若检测得到某个CPU核的负载超过第一预设负载阈值(例如80％等)，则可将该CPU核确定为异常CPU核。进一步的，终端可获取异常CPU核上运行的APP的负载状态，获取上述异常CPU核上的异常APP，其中，上述异常APP的负载占异常CPU核的总负载的比例大于预设比例阈值的APP。进一步的，上述异常APP还可为网络输入输出(英文：input/output，IO)速率小于预设速率阈值的APP。比如，终端可将连续3个周期的负载占异常CPU的总负载比例超过50％，并且网络IO速率小于10Kbits/s的APP确定为异常APP。具体实现中，上述异常APP也可为存在被攻击等风险的APP，具体可根据终端的实际应用场景或者软硬件配置等情况确定，在此不做限制。
在一些可行的实施方式中，终端检测得到终端中的异常APP之后，则可对上述异常APP运行可占用的CPU资源进行管制。具体的，终端可将上述异常APP所能占用的CPU资源设定为第三CPU资源。其中，上述第三CPU资源可为空，也可为异常CPU核上的预设比例3的可占用时长。例如，终端可将上述异常APP占用异常CPU核的时长设定为第一时长，异常CPU核上的其他APP占用异常CPU核的时长设定为第二时长，进而可设定第一时长占CPU核的可占用时长的5％，第二时长占CPU核的可占用时长的95％等。
具体实现中，终端检测得到异常APP之后，可直接对异常APP进行冻结或者直接结束异常APP，此时，异常APP所占用的第三CPU资源为空。此外，若上述异常APP需要收发消息，并且也为用户常用的APP，则可将异常APP设置在上述第一时长上运行，通过可占用时长的限制来控制异常APP的运行对其他APP的运行造成影响。如图5，图5为本发明实施例提供的CPU资源的另一分配示意图。若上述异常APP为用户常用的APP，或者上述异常APP需要收发信息，则可将上述异常APP的可占用CPU资源设定为CPU核的5％的可占用时间。若异常APP在异常CPU核上运行的时间超过CPU核在一个运行周期内的可占用时间的5％，则需要退出将CPU核让给其他APP，等待下一个运行周期。
参见图6，图6是本发明实施例提供的另一应用程序管理操作示意图。如图6，在本发明实施例中，终端可在原有的后台控制组中包含的后台控制分组和系统后台控制组之外建 立关键后台控制组，将后台APP中的关键APP放入关键后台控制组中，并为关键后台控制组分配资源，关键后台控制组所拥有的资源比后台控制分组多，进而可保障关键后台控制组中包含的APP的运行顺畅，增强了终端APP的运行状态的可控性。进一步的，终端可对后台控制组中包含的异常APP进行CPU资源的限额管制(单个CPU核的可占资源5％等)或者对异常APP的运行进行冻结或者结束(占用的CPU资源为空)等管理，避免异常APP占用太多CPU资源，影响其他APP的正常运行，提高了终端APP的管理的适用性，增强了终端的用户体验。
以上主要介绍了本发明实施例提供的方法的具体流程，下面结合图7并以Android操作系统为例，介绍本发明实施例提供的方法的实现位置和运行时状态，更具体的方法流程可参考前述实施例。
请参阅图7，为本发明实施例提供的计算机系统的结构示意图。该计算机系统可以是上述本发明实施例提供的终端设备，也可以是其他类型的计算机设备。该计算机系统包括应用层710、操作系统层700和硬件层750。
其中，上述操作系统可以为Android操作系统，也可为其他适用于本发明实施例提供的方法的操作系统，在此不做限制。操作系统层450又分为系统服务层720、核心库层730和内核层740。其中，图7中的操作系统层700可以认为是图1中操作系统182的一种具体实现。系统服务层720包括业务状态信息采集、CPU调度决策和CPU调度执行器等。需要说明的是，图7是以CPU这种处理器为例的示意图，具体实现中，CPU也可替换为ARM，具体可根据实际应用程序确定，在此不做限制。核心库层730包括CPU信息采集库、CPU分组管理和CPU分组任务管理库等。内核层740可包括CPU资源调度、CPU控制组合CPUSET控制组等。
在一些可行的实施方式中，系统服务器层720中的业务状态信息采集用于采集应用层710中各个应用的业务状态信息。其中，各个应用的业务状态信息包括应用在前台运行和后台运行的前后台属性变化，或者应用的运行或者结束等运行状态变化等。本发明实施例可通过系统服务层720中的业务状态信息采集获取系统后台应用程序中处于预设运行状态的第一目标应用程序，进而可通过系统服务层720中的CPU调度决策确定为第一目标应用程序分配的第一处理资源。系统服务层720中的CPU调度决策用于根据应用状态信息采集模块采集到的应用状态信息确定分配给第一目标应用程序的CPU资源。系统服务层720中的CPU调度执行器用于根据CPU调度决策模块确定的分配给第一目标应用程序的CPU资源，设置第一目标应用程序对应的应用进程的可占用CPU资源，包括可占用的CPU核以及单个的可占用时长等。进一步的，CPU调度执行器设置好第一目标应用程序对应的应用进程的可占用CPU资源之后，则可通过核心库层730和内核层740中各个模块执行CPU资源的分配和调度。
具体实现中，核心库层730中包含的CPU信息采集库用于为系统服务层720提供的CPU的负载状态等CPU信息。CPU调度决策模块确定分配给第一目标应用程序的CPU资源时可根据CPU信息采集库提供的各个CPU核的负载状态确定分配给第一目标应用程序的CPU核(具体可为某一个或者多个CPU核)，进而可通过CPU调度执行器进行CPU决策的执行。核心库层730中的CPU分组管理可根据CPU调度执行器设置的CPU资源的分 配方式对系统中包含的CPU核进行分组管理，进而可通过CPU分组任务管理库对各个CPU分组(具体可为CPU核的分组)中的CPU核进行任务管理。其中，CPU分组管理用于为前台控制组分配CPU核(即系统包含的所有CPU核)，或者为后台控制组分配系统中包含的某一个CPU核，或者为关键后台控制组分配系统包含的CPU核中的一个或者多个等，进而可实现CPU核的分组。上述CPU核的任务管理包括各个CPU核上运行的应用进程的添加与减少等应用进程管理。
进一步的，内核层740中的CPU控制组可根据CPU分组任务管理库对各个CPU核的任务管理情况对各个CPU核的可占用时间进行控制管理。例如，前台控制组中包含的应用程序可占用每个CPU核的95％的可占用时长，后台控制组中包含的应用程序可占用其可占用的CPU核的5％的可占用时长等。若CPU分组任务管理库对各个CPU核的任务管理过程中出现了任务分配异常的CPU核(如上述异常CPU核)，CPU控制组可将异常应用程序占用异常CPU核的可占用时长控制在5％等。CPUSET控制组用于对CPU分组管理分配的各个CPU分组包含的CPU核进行控制。CPU调度执行器确定的CPU资源的调度执行可通过CPUSET控制组进行控制，最后通过CPU资源调度进行硬件层750上的CPU的调度。CPU资源调度用于执行根据CPU控制组和CPUSET控制组的控制指令，进而实现对硬件层750中的中央处理器的调度。
进一步的，如图7，终端的应用层710可包括电话、联系人(即通讯录)、即时通讯、图库、音乐、媒体播放器、地图导航、以及浏览器等。其中，图7中的应用层710可以认为是图1中应用程序181的一种具体实现，在此不做限制。终端的硬件层750包括中央处理器(即CPU)、图形处理器、存储器、输入设备和显示设备等。其中，中央处理器和图形处理器可相当于图1中的处理器150的一种具体实现)存储器可相当于图1中的存储器180，包括内存和外存。图7中的输入设备可相当于图1中的输入设备132，图7中的显示设备455可相当于图1中的显示设备140，例如液晶显示器(英文：Liquid Crystal Display，LCD)、全息成像(英文：Holographic)、投影(英文：Projector)等。当然除此之外，硬件层750还可以包括一个或多个传感器(相当于图1中的传感器120)。硬件层750还可以包括图1中示出的电源、摄像头、RF电路和WiFi模块，还可以包括图1中也没有示出的其他硬件模块，例如内存控制器和显示控制器等，在此不做限制。
