具体实施方式
本发明实施例提一种操作***热切换的方法，能一定程度上保证多个操作***对硬件资源的互斥访问和协调使用，从而保证了操作***切换后硬件资源使用的可靠性。本发明实施例还提供了相应的装置及移动终端。以下分别进行详细说明。
为了使本技术领域的人员更好地理解本发明方案，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的实施例，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做出创造性劳动前提下所获得的所 有其他实施例，都应当属于本发明保护的范围。
参阅图1，为本发明实施例提供的移动终端的操作***和硬件资源架构的原理示意图，其中：
移动终端同时可以运行多个操作***，如：操作***1、操作***2，直至操作***n，n为大于2的整数，移动终端中包含的多个操作***是分时复用的，在一个时间段内只能有一个操作***在前台运行，其他操作***都在后台运行。如图1中，操作***1为前台操作***，操作***2，直至操作***n都为后台操作***。
本发明实施例中的前台操作***为运行在前台的操作***，可以与用户交互的操作***，后台操作***为运行在后台的操作***，不能与用户进行交互。
移动终端的硬件资源包括移动终端的内部硬件资源，以及与移动终端通过热插拔接口建立连接的热插拔硬件资源，本发明实施例中的硬件资源为所述移动终端中用于与外部交互的硬件资源，内部硬件资源可以包括移动终端wifi模块、蓝牙模块、近距离无线通信(NFC，Near Field Communication)模块、音频模块、视频模块、显示屏、摄像头等可与外部交互的硬件资源，热插拔硬件资源可以包括通过通用串行总线(Universal Serial Bus，USB)接口连接的USB设备、安全数码(Secure Digital，SD)卡，通过在线直传(OTG，On-The-Go)接口连接的OTG设备等都属于热插拔硬件资源。
参阅图2，为本发明实施例提供的移动终端的操作***和硬件资源架构的另一原理示意图，其中：
针对每个操作***对应的硬件资源，在软件层面会维护一个针对该操作***的内部资源管理服务，如针对操作***1至操作***n都对应有wifi、NFC、蓝牙等资源管理服务程序，在操作***1为当前的前台操作***时，与该操作***1对应的内部资源管理服务启动，在操作***2至操作***n都只在后台运行时，与操作***2至操作***n对应的内部资源管理服务阻塞，同时，针对每个内部资源管理服务都有其对应的资源管理线程组，如：操作***1为当前的前台操作***时，则与操作***1对应的内部资源管理服务和资源管理线程都处于启动状态，其他操作***都只在后台运行，则与其他操作***对应的内部 资源管理服务和资源管理线程都处于阻塞状态。
在内核中会维护每个操作***各自对应的资源管理命名空间，在每个资源管理命名空间包括与其对应的操作***的运行状态信息，所述运行状态信息用于指示所述操作***为前台操作***或后台操作***，并用于指示所述移动终端中的硬件开放对前台操作***的使用或屏蔽对后台操作***的使用，例如：图2中操作***1的资源管理命名空间中操作***1的状态：前台，则表示该操作***1为前台操作***，内部硬件资源使用状态：可用，则表示操作***1可以使用内部硬件资源。图2中操作***2的资源管理命名空间中操作***2的状态：后台，则表示该操作***2为后台操作***，内部硬件资源使用状态：禁用，则表示操作***2不可以使用内部硬件资源。
这样，各资源管理线程读取到资源管理命名空间1中的操作***1的状态为前台后，与操作***1对应的资源管理线程就会启动，与其他操作***对应的资源管理线程都会阻塞，与操作***1对应的内部资源管理服务也会启动，与其他操作***对应的内部资源管理服务都会阻塞。
在操作***1为前台操作***时，资源管理线程会允许操作***1调用内部硬件资源，其他操作***运行在后台，资源管理线程会阻塞其他操作***对内部硬件资源的调用。则实现了多个操作***对硬件资源的互斥使用。
在操作***热切换时，可以参阅图3理解本发明实施例的操作***热切换过程：
本发明实施例以基于Linux内核的Android手机上运用的实施方案为例进行说明，android手机操作***是一个基于Linux Kernel的分层智能手机操作***，其分为5层，从上到下分别是应用层(Java Application)、框架层(Frameworks)、***运行库层(User Libraries)、内核层(Linux Kernel)和硬件层。
在本发明实施例中，在应用层设置了操作***切换接口(SystemSwitch)，为操作***切换的入口，以安卓安装包(AndroidPackage，APK)的形式存在于移动终端的桌面上，点击APK后可以为用户提供操作***切换的界面。
在框架层，针对内部资源服务设置内部资源管理线程(Resource  management thread)，操作***启动时跟随各个内部资源管理器而启动，一方面通过内核记录资源管理命名空间的前台操作***的标识来获取当前的前台操作***，使当前的前台操作***能够正常使用内部硬件资源，后台操作***无法使用内部硬件资源，另一方面监控操作***切换APK发送的切换事件，当当前的前台操作***收到切换事件时，首先释放本操作***占用的内部硬件资源并通知内核，内核确保所有内部硬件资源释放完成后再进行操作***切换。
在框架层，针对热插拔硬件资源，设置外部资源管理服务，对服务进行修改，当有热插拔设备***移动终端时，对kernel发送的热插拔设备***Uevent消息进行截取，接收到热插拔设备***消息时读取当前的前台操作***，当前的前台操作***绑定***的热插拔设备，后台的操作***进行屏蔽，对内核发送的热插拔设备拔出Uevent消息进行截取，对未绑定该热插拔设备的操作***进行屏蔽。
在内核层建立多操作***需要使用的节点，并对外提供相应的节点接口，如用于获取当前的前台操作***的接口、用于判断当前是否正在切换操作***的接口等。
本发明运用在基于Linux内核的Android手机上多个操作***切换时，对内部硬件资源管理的过程可以参阅图4进行理解：
步骤1：移动终端开机后，会自动启动一个前台操作***，例如：操作***1，操作***1启动之后，与操作***1对应的各个资源管理线程读取操作***1的资源管理空间的操作***状态信息和内部硬件资源使用细腻系，开放操作***1对于内部硬件资源的调用，资源管理线程调用kernel的开始切换节点，此时没有切换事件输入，开始切换节点为阻塞节点。
步骤2：用户通过桌面上的System Switch，选择将操作***2切换到前台，这个动作会调用内核提供的切换接口，通知内核操作***切换事件发生。
步骤3：内核接收到上层APK发下来的切换事件，将所有资源管理线程的开始切换节点释放。
步骤4：内核通知完各个线程操作***切换开始后，进入等待状态，等待各个资源管理线程反馈资源释放情况。
步骤5：资源管理线程阻塞解除，开始工作，开始释放当前占用的内部硬件资源。
步骤6：硬件资源释放完成后，调用内核提供的接口，如NFC资源释放完成接口，通知内核当前线程监控的资源已经释放完毕。
步骤7：当资源管理线程向内核反馈资源已释放完成之后再次进入阻塞状态，等待内核通知***切换完成。
步骤8：当内核检测到所有资源管理线程全部反馈其所监控的内部硬件资源释放完毕之后，解除当前等待状态，通知各个管理线程操作***切换完成。
步骤9：资源管理线程阻塞解除，开始工作，开放切换到前台的操作***2对于内部资源的调用，并重新进入阻塞状态，等待下一次切换的到来。
在操作***1到操作***2的切换过程中，将操作***1的资源管理命名空间中的操作***1状态修改为后台，将操作***1的内部硬件资源使用状态修改为禁用。将操作***2的资源管理命名空间中的操作***2状态修改为前台，将操作***2的内部硬件资源使用状态修改为可用。
本发明以运行在基于Linux内核的Android手机上多个操作***对内部硬件资源管理的过程为例进行说明，可以参阅图5进行理解：
热插拔设备的***流程如下：
步骤1：用户将热插拔设备A***手机。
步骤2：内核检测到热插拔设备A已***，发送Uevent消息给各个操作***的热插拔设备A管理器(图3中框架层的外部资源管理服务)。
步骤3：热插拔设备A管理器接收到内核发送的热插拔设备A***的Uevent消息之后，判断当前热插拔设备A管理器所在的操作***前台操作***还是后台操作***：如果是后台操作***，则直接返回，屏蔽这个Uevent消息；如果是后台操作***，则进入步骤4。
步骤4：前台操作***接收到热插拔设备A的***消息后，添加当前热插拔设备A的在位状态，然后允许外设A的管理器继续处理这条Uevent消息，之后热插拔设备A与当前处于激活状态的操作***绑定了，可以被当前***正常使用，即使发生了***切换也不会与绑定的***解除绑定。
热插拔设备的拔出流程如下：
步骤5：用户将热插拔设备A拔出手机。
步骤6：内核检测到热插拔设备A已拔出，发送Uevent消息给各个操作***的热插拔设备A的管理器。
步骤7：热插拔设备A的管理器接收到内核发送的热插拔设备A拔出Uevent消息之后，判断当前管理器所在的操作***的热插拔设备A是否在位：如果不在位，则直接返回，屏蔽这个Uevent消息；如果在位，则进入步骤8。
步骤8：热插拔设备A在位的操作***接收到热插拔设备A的拔出消息后，将热插拔设备A的在位标记清除，然后允许热插拔设备A的管理器继续处理这条Uevent消息，之后热插拔设备A的管理器与原来绑定的***解除绑定了，重新***后就可以与当前的前台操作***绑定了，并供当前的前台操作***正常使用。
本发明实施例中，在位标记可以维护在各个操作***的资源管理空间中。与现有技术中经常会出现多个操作***同时对同一硬件资源进行使用的情况，导致硬件资源使用异常相比，本发明实施例提供的操作***热切换的方法，可以在操作***热切换时，先释放掉当前的前台操作***所占用的硬件资源，并通过资源管理命名空间中的运行状态信息指示硬件资源屏蔽后台操作***对硬件资源的访问，一定程度上保证多个操作***对硬件资源的互斥访问和协调使用，从而保证了操作***切换后硬件资源使用的可靠性。
本发明实施例提供的操作***热切换的方法，移动终端运行的多套***热切换时，能确保切换前的前台操作***所占用的内部硬件资源释放完成，在切换到前台操作***后可以保证内部硬件资源被切换后的操作***的正常使用，防止出现概率性个别资源由于抢占使用导致功能异常。
