Description

移动终端与显示设备之间的一键连接方法及系统 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种移动终端与显示设备之间的一键连接方法及系统。
背景技术
Miracast是Wi-Fi Alliance于2012年9月19日宣布启动的Wi-Fi CERTIFIED MiracastTM认证项目。Miracast设备提供简化发现和设置，用户可以迅速在设备间传输视频。用户能把通过Miracast认证的手机、平板电脑或笔记本显示的视频内容以无线方式投射到支持Miracast技术的接收装置上，例如电视机、投影仪或显示器。用户在手机、平板电脑或笔记本上看到的视频内容与电视机、投影仪或显示器上的视频内容是一模一样的。很多智能设备上把Miracast功能称为无线显示。
Miracast通过Wi-Fi CERTIFIED Wi-Fi DirectTM形成连接，它允许无线网络中的设备无需通过无线路由器而以点对点形式互连。但是两个Miracast设备比如手机和电视进行Miracast连接实际操作过程显得比较复杂，以手机和电视为例：电视作为视频内容接收端，需要在设置界面中找到Miracast(无线显示)界面，然后开启Miracast功能，等待手机连接；同样，手机端需要到设置里面找到无线显示设置界面并开启无线显示功能，然后选择电视设备进行Miracast连接，操作非常繁琐。
发明内容
本发明实施例提供一种移动终端与显示设备之间的一键连接方法及系统，用以解决移动终端与显示设备之间的Miracast连接操作繁琐的问题。
本发明实施例提供了一种移动终端与显示设备之间的一键连接方法，包括：
显示设备接收到移动终端广播的无线保真探测请求帧，并判断所述无线保真探测请求帧中携带的身份标识字段的内容与预置的标识内容是否相同；
若相同，则所述显示设备在接收到用户确认Miracast连接的指示命令之后，向所述移动终端发送无线保真探测响应帧，以令所述移动终端触发与所述显示设备之间的Miracast连接。
相应地，本发明实施例还提供了一种移动终端与显示设备之间的一键连接方法，包括：
移动终端通过广播发送无线保真探测请求帧后，接收来自显示设备的无线保真探测响应帧，并根据所述无线保真探测响应帧确定所述显示设备接受Miracast连接；所述无线保真探测请求帧和无线保真探测响应帧均携带有身份标识字段；
所述移动终端将携带身份标识字段的无线保真直接帧发送至所述显示设备，完成所述移动终端与所述显示设备之间的一键Miracast连接。
相应地，本发明实施例还提供了一种显示设备，所述显示设备包括：
判断模块，用于接收所述移动终端广播的无线保真探测请求帧，并判断所述无线保真探测请求帧中携带的身份标识字段的内容与预置的标识内容是否相同；
发送模块，用于若相同，则在接收到用户确认Miracast连接的指示命令之后，向所述移动终端发送无线保真探测响应帧，以令所述移动终端触发与所述显示设备之间的Miracast连接。
相应地，本发明实施例还提供了一种移动终端，所述移动终端包括：
接收并确定模块，用于在移动终端通过广播发送无线保真探测请求帧后，接收来自显示设备的无线保真探测响应帧，并根据所述无线保真探测请求帧确定所述显示设备接受Miracast连接；所述无线保真探测请求帧和无线保真探测响应帧均携带有身份标识字段；
直接帧发送模块，用于将携带身份标识字段的无线保真直接帧发送至所述显示设备，完成所述移动终端与所述显示设备之间的一键Miracast连接。
相应地，本发明实施例还提供了一种连接系统，所述系统包括如本发明实施例所述显示设备，和，如本发明实施例所述移动设备。
相应地，本发明实施例还提供了一种在其上记录有用于执行本发明实施例所述方法的程序的计算机可读存储介质。
本发明实施例提供的一种移动终端与显示设备之间的一键连接方法及系 统，在移动终端上设置Miracast键，不需要在设置界面中开启无线显示功能搜索对方设备、选择设备进行Miracast连接，只需要按下Miracast键即可自动寻找到对端Miracast设备(以显示设备为例)并触发Miracast连接；在移动终端按下Miracast键后，移动终端开启Miracast连接功能，向外广播携带身份标识字段的无线保真探测请求帧，显示设备接收到移动终端广播的无线保真探测请求帧，确定其中的身份标识字段的内容与预置的标识内容相同，则会弹出对话框让用户确认是否要进行Miracast连接，用户确认后，显示设备发送同样携带身份标识字段的无线保真探测响应帧至移动终端，移动终端收到无线保真探测响应帧后，确认显示设备接受Miracast连接，触发与显示设备之间的Miracast连接。在上述过程中，移动终端和显示设备均不需要在设置界面中开启无线显示功能并等待连接，减少了用户的操作步骤，降低了Miracast连接的实现难度，提升了用户体验。

步骤100，移动终端将无线保真探测请求帧广播出去。
移动终端的Miracast键被按下或被点击之后，移动终端的框架将开启无线保真指示(wifi direct)功能，在无线保真探测请求帧中添加无线保真对等网络字段和身份标识字段，然后通过广播(Broadcas)方式发送无线保真探测请求帧。
其中，无线保真对等网络字段为移动终端开启Miracast功能默认存在的。
在本发明的一个优选的实施例中，身份标识字段可以包括组织唯一识别符(Organizationally unique identifier，OUI)和定义(Value)，在OUI和Value中填写独有的辨识信息。
步骤102，显示设备接收到移动终端广播的无线保真探测请求帧，并判断所述无线保真探测请求帧中携带的身份标识字段的内容与预置的标识内容是否相同，若相同，则执行步骤104；若不同，则流程结束。
在本发明的一个优选的实施例中，显示设备接收到无线保真探测请求帧后，汇报给用户界面(User Interface，UI)，UI弹出提示框提示用户是否接受Miracast连接。
步骤104，所述显示设备在接收到用户确认Miracast连接的指示命令之后，向所述移动终端发送无线保真探测响应帧。
用户确认接受Miracast连接，触发显示设备的框架开启wifi direct功能，向所述移动终端发送无线保真探测响应帧。
在本发明的一个优选的实施例中，无线保真探测响应帧包括无线保真对等网络字段和身份标识字段。
需要说明的是，所述无线保真探测响应帧中的身份标识字段的内容与所述无线保真探测请求帧中的身份标识字段的内容相同。
步骤106，移动终端根据所述无线保真探测响应帧确定所述显示设备接受Miracast连接。
在本发明的一个优选的实施例中，移动终端将所述无线保真探测响应帧传输至所述移动终端的框架，通过所述框架确定所述无线保真探测响应帧中的身份标识字段的内容与所述无线保真探测请求帧中的身份标识字段的内容相同，确定所述显示设备接受Miracast连接。
步骤108，所述移动终端将携带身份标识字段的无线保真直接帧发送至所述显示设备，完成所述移动终端与所述显示设备之间的一键Miracast连接。
无线保真直接(wifi direct)帧可以包括：供应发现(provision discovery)、协商请求(egotiation request)和协商确认(egotiation confirm)帧。
综上所述，本发明实施例提供的一种移动终端与显示设备之间的一键连接方法，在移动终端上设置Miracast键，不需要在设置界面中开启无线显示功能搜索对方设备、选择设备进行Miracast连接，只需要按下Miracast键即可自动寻找到对端Miracast设备(以显示设备为例)并触发Miracast连接；在移动终端按下Miracast键后，移动终端开启Miracast连接功能，向外广播携带身份标识字段的无线保真探测请求帧，显示设备接收到移动终端广播的无线保真探测请求帧，确定其中的身份标识字段的内容与预置的标识内容相同，则会弹出对话框让用户确认是否要进行Miracast连接，用户确认后，显示设备发送同样携带身份标识字段的无线保真探测响应帧至移动终端，移动终端收到无线保真探测响应帧后，确认显示设备接受Miracast连接，触发与显示设备之间的Miracast连接。在上述过程中，移动终端和显示设备均不需要在设置界面中开启无线显示功能并等待连接，减少了用户的操作步骤，降低了Miracast连接的实现难度，提升了用户体验。
