Description

手机上WiHD传输的控制方法、装置及手机
本申请要求在2015年11月06日提交中国专利局、申请号为201510756753.X、申请名称为“手机上WiHD传输的控制方法、装置及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信技术领域，尤其涉及一种手机上无线高清WiHD传输的控制方法、装置及手机。
背景技术
无线高清(Wireless High Definition，WiHD)技术是一种高速无线传输技术，它运用了60千兆赫兹(GHz)频段(毫米波)的频谱，能够取得更大的数据传输速率，其最初的传输速率便高达4Gbps，从而能更可靠地提供传输高质量、高清晰度无压缩视频所必要的频宽。
WiHD技术可以作为其他所有无线局域网(Wireless Local Area Networks，WLAN)及局域网(Local Area Networks，LAN)技术的补充，WLAN或LAN被用来在家庭内传输数据，而当内容传送到室内进行无线显示时，WiHD将凭借其能够显示高质量的、高清晰度的、无压缩的、无损的视频的特点而成为最佳选择。
WiHD技术可以应用于手机上，手机在使用WiHD功能时，能够将手机屏幕上的内容投放到电视上。相关技术中，手机在亮屏的状态下，会通过WiHD技术将手机屏幕上的内容投放到电视上，而当手机灭屏时，WiHD功能就会被关闭，这主要是由于以下的两个原因：第一个原因是，手机灭屏时，手机屏幕上没有内容显示，所以此时不需要使用WiHD将手机内容继续投放到电视上；第二个原因是，手机灭屏时，为了降低功耗，需要将WiHD功能关闭。因此，在一般的应用场景下，当手机灭屏时，WiHD需要被关闭。
在应用中，用户使用手机播放音乐时，即使手机灭屏，此时用户依然希望将手机中的音乐继续利用WiHD投放到电视上，但是实际上却是，由 于手机灭屏导致直接关闭了WiHD功能，从而使手机中的音乐无法继续通过WiHD投放到电视上。
发明内容
本发明实施例的目的在于提供一种手机上WiHD传输的控制方法、装置及手机，在手机播放音乐时，即使手机灭屏，也能够将手机播放的音乐继续通过WiHD进行传输，提升用户体验。

根据监听结果处理所述手机上无线高清WiHD传输的状态转换。
进一步地，上述方法还可具有以下特点，还包括：
接收手机进入亮屏状态的消息；
在接收到手机进入亮屏状态的消息后，终止对所述内核通知“PM_SUSPEND_PREPARE”的监听。
进一步地，上述方法还可具有以下特点，所述根据监听结果处理所述手机上无线高清WiHD传输的状态转换包括：
在所述监听结果为监听到所述内核通知“PM_SUSPEND_PREPARE”时，关闭手机上的WiHD传输。
进一步地，上述方法还可具有以下特点，所述根据监听结果处理所述手机上无线高清WiHD传输的状态转换包括：

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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。
图1为本发明实施例一中手机上WiHD传输的控制方法的流程图。图1所示的手机上WiHD传输的控制方法应用于手机。如图1所示，本实施例中，手机上WiHD传输的控制方法可以包括如下步骤：
步骤S101，接收手机进入灭屏状态的消息；
其中，手机的灭屏状态是指手机屏幕关闭的状态。
在具体应用中，可以通过多种方式知道手机进入灭屏状态。例如，很多手机具有屏幕自动关闭的功能。当到达用户设置的屏幕自动关闭时长时，屏幕就会自动关闭，即进入灭屏状态。这种情况下，到达用户设置的屏幕自动关闭时长，即可认为是接收到了手机进入灭屏状态的消息。
再比如，手机灭屏时，屏幕亮度会突然降低，由一个较高的值变为一个较低的值，那么，当屏幕亮度值由高变低时即可认为接收到了手机进入灭屏状态的消息。
步骤S102，在接收到手机进入灭屏状态的消息后，监听该手机的内核通知“PM_SUSPEND_PREPARE”；
在手机后台没有播放音乐的情况下，手机灭屏后，手机即会试图进入睡眠，从而引发手机内核发送内核通知“PM_SUSPEND_PREPARE”。但是，如果手机灭屏后，后台仍然在播放音乐，手机就不会试图进入睡眠，所以手机内核就不会发送内核通知“PM_SUSPEND_PREPARE”。
基于这一机制，本步骤在手机灭屏后，先不立刻关闭WiHD，而是开始监听内核通知“PM_SUSPEND_PREPARE”。如果收到内核通知“PM_SUSPEND_PREPARE”，说明此时手机后台没有播放音乐，就关闭WiHD；如果没有收到此内核通知“PM_SUSPEND_PREPARE”，说明此时 手机后台正在播放音乐，由于此时用户仍然希望将手机后台播放的音乐通过WiHD传输到其他设备(比如电视)上，所以此时就保持WiHD的开启状态。
在本发明实施例中，可以通过在手机内核中注册监听函数来监听内核通知“PM_SUSPEND_PREPARE”。
步骤S103，根据监听结果处理该手机上WiHD传输的状态转换。
WiHD传输的状态指WiHD关闭和WiHD开启。
在本发明实施例中，根据监听结果处理该手机上WiHD传输的状态转换可以包括：
在监听结果为监听到内核通知“PM_SUSPEND_PREPARE”时，关闭手机上的WiHD传输。
在本发明实施例中，根据监听结果处理该手机上WiHD传输的状态转换还可以包括：
在监听结果为未监听到内核通知“PM_SUSPEND_PREPARE”时，保持手机上WiHD传输的开启状态。
本发明实施例的手机上WiHD传输的控制方法，在手机播放音乐时，即使手机灭屏，也能够保持WiHD传输的开启状态，从而能够将手机播放的音乐继续通过WiHD进行传输，提升用户体验。
图2为本发明实施例二中手机上WiHD传输的控制方法的流程图。图2所示的手机上WiHD传输的控制方法应用于手机。如图2所示，本实施例中，手机上WiHD传输的控制方法可以包括如下步骤：
步骤S201，接收手机进入灭屏状态的消息；
步骤S202，在接收到手机进入灭屏状态的消息后，监听该手机的内核通知“PM_SUSPEND_PREPARE”；
在本发明实施例中，可以通过在手机内核中注册监听函数来监听内核通知“PM_SUSPEND_PREPARE”。
步骤S203，根据监听结果处理该手机上WiHD传输的状态转换。
步骤S204，接收手机进入亮屏状态的消息；
其中，手机的亮屏状态是指手机屏幕开启的状态。
在具体应用中，也可以通过多种方式知道手机进入亮屏状态。例如，很多手机具有屏幕锁定功能，当用户解除屏幕锁定时，屏幕就会自动开启， 即进入亮屏状态。这种情况下，用户解除屏幕锁定时，即可认为是接收到了手机进入亮屏状态的消息。
再比如，同手机灭屏相反，手机亮屏时，屏幕亮度会突然升高，由一个较低的值变为一个较高的值，那么，当屏幕亮度值由低变高时即可认为接收到了手机进入亮屏状态的消息。
步骤S205，在接收到手机进入亮屏状态的消息后，终止对内核通知“PM_SUSPEND_PREPARE”的监听。
相应于步骤S202，在本发明实施例中，可以通过在手机内核中取消监听函数来终止监听内核通知“PM_SUSPEND_PREPARE”。
由于WiHD的功能就是在手机处于亮屏状态时，将手机屏幕上显示的内容传输到电视等其他设备上进行显示，因此在亮屏状态，WiHD会保持开启的状态，此时不需要再通过对内核通知“PM_SUSPEND_PREPARE”的监听来决定是否要继续保持WiHD传输的开启了。所以本步骤在接收到手机进入亮屏状态的消息后，就终止对内核通知“PM_SUSPEND_PREPARE”的监听。由于该终止操作会引起手机中相应程序的关闭，因此这可以节约手机的内存资源，提高手机的响应速度。
本发明实施例的手机上WiHD传输的控制方法，在手机播放音乐时，即使手机灭屏，也能够保持WiHD传输的开启状态，从而能够将手机播放的音乐继续通过WiHD进行传输，提升用户体验。并且，本发明实施例的手机上WiHD传输的控制方法，在手机亮屏状态时，会自动终止对内核通知“PM_SUSPEND_PREPARE”的监听，节约手机的内存资源，提高手机的响应速度。
