Description

一种传输控制方法及设备 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种传输控制方法及设备。
背景技术
无线局域网技术使得用户可以便捷的以无线方式随时随地的访问网络资源。无线保真(Wireless Fidelity，Wi-Fi)作为无线局域网(wireless local area network，WLAN)技术中的一种得到了广泛应用。其中，设备在连接至Wi-Fi热点后，便可以通过Wi-Fi热点提供的Wi-Fi网络传输数据。
但是，在设备与Wi-Fi热点建立Wi-Fi连接的过程中，如果Wi-Fi连接出错，那么，设备只能在进行错误提示后，响应于用户的操作重新连接Wi-Fi热点。在Wi-Fi连接出错后，需要用户介入，设备才可以重新建立Wi-Fi连接。设备建立Wi-Fi连接的效率较低。
另外，设备通过Wi-Fi网络传输文件的过程中，传输双方只要一方的Wi-Fi连接出现问题，就会导致文件传输错误。而另一方无法及时感知到文件传输错误，需要用户介入，双方设备才可以重新建立Wi-Fi连接，从而继续传输文件。

操作系统等。
触摸屏204可以包括触敏表面204-1和显示器204-2。其中，触敏表面204-1(例如触控面板)可采集手机200的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触敏表面204-1上或在触敏表面204-1附近的操作)，并将采集到的触摸信息发送给其他器件例如处理器201。其中，用户在触敏表面204-1附近的触摸事件可以称之为悬浮触控。悬浮触控可以是指，用户无需为了选择、移动或拖动目标(例如图标等)而直接接触触控板，而只需用户位于终端附近以便执行所想要的功能。在悬浮触控的应用场景下，术语“触摸”、“接触”等不会暗示用于直接接触触摸屏，而是在其附近或接近的接触。能够进行悬浮触控的触敏表面204-1可以采用电容式、红外光感以及超声波等实现。触敏表面204-1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，再发送给处理器201，触摸控制器还可以接收处理器201发送的指令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触敏表面204-1。显示器(也称为显示屏)204-2可用于显示由用户输入的信息或提供给用户的信息以及手机200的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器204-2。触敏表面204-1可以覆盖在显示器204-2之上，当触敏表面204-1检测到在其上或附近的触摸事件后，传送给处理器201以确定触摸事件的 类型，随后处理器201可以根据触摸事件的类型在显示器204-2上提供相应的视觉输出。虽然在图2中，触敏表面204-1与显示屏204-2是作为两个独立的部件来实现手机200的输入和输出功能，但是在某些实施例中，可以将触敏表面204-1与显示屏204-2集成而实现手机200的输入和输出功能。可以理解的是，触摸屏204是由多层材料堆叠而成，本申请实施例中只展示出了触敏表面(层)和显示屏(层)，其他层在本申请实施例中不予记载。另外，在本申请其他一些实施例中，触敏表面204-1可以覆盖在显示器204-2之上，并且触敏表面204-1的尺寸大于显示屏204-2的尺寸，使得显示屏204-2全部覆盖在触敏表面204-1下面，或者，上述触敏表面204-1可以以全面板的形式配置在手机200的正面，也即用户在手机200正面的触摸均能被手机200感知，这样就可以实现手机200正面的全触控体验。在其他一些实施例中，触敏表面204-1以全面板的形式配置在手机200的正面，显示屏204-2也可以以全面板的形式配置在手机200的正面，这样在手机200的正面就能够实现无边框的结构。

定位装置208，用于为手机200提供地理位置。可以理解的是，该定位装置208具体可以是全球定位系统(Global Positioning System，GPS)、北斗卫星导航系统等定位系统的接收器。定位装置208在接收到上述定位系统发送的地理位置后，将该信息发送给处理器201处理，或者发送给存储器203保存。在另外的一些实施例中，该定位装置208可以是辅助全球卫星定位系统(Assisted Global Positioning System，AGPS)的接收器。AGPS是一种在一定辅助配合下进行GPS定位的运行方式，它可以利用基站的信号，配合GPS卫星信号，可以让手机200定位的速度更快；在AGPS系统中，该定位装置208可通过与辅助定位服务器(例如手机200定位服务器)的通信而获得定位辅助。AGPS系统通过作为辅助服务器来协助定位装置208完成测距和定位服务，在这种情况下，辅助定位服务器通过无线通信网络与终端例如手机200的定位装置208(即GPS接收器)通信而提供定位协助。
音频电路209、扬声器213、麦克风214可提供用户与手机200之间的音频接口。音频电路209可将接收到的音频数据转换后的电信号，传输到扬声器214，由扬声器213转换为声音信号输出；另一方面，麦克风214将收集的声音信号转换为电信号，由音频电路209接收后转换为音频数据，再将音频数据输出至RF电路202以发送给比如另一手机，或者将音频数据输出至存储器203以便进一步处理。

手机200还可以包括给各个部件供电的电源装置211(比如电池和电源管理芯片)，电池可以通过电源管理芯片与处理器201逻辑相连，从而通过电源装置211实现管理充电、放电、以及功耗管理等功能。
尽管图2未示出，手机200还可以包括摄像头(前置摄像头和/或后置摄像头)、闪光灯、微型投影装置、近场通信(Near Field Communication，NFC)装置等，在此不予赘述。
以下实施例中的方法均可以在具有上述硬件结构的手机200中实现。
在本申请实施例的第一种应用场景中，本申请实施例的方法可以应用于STA 102或者STA 103与AP 101(即Wi-Fi热点)建立Wi-Fi连接的过程中。本申请实施例这里以STA 102与AP 101建立Wi-Fi连接为例，对本申请实施例的方法进行说明：
其中，STA 102与AP 101建立Wi-Fi连接的过程，具体可以包括图3所示的扫描过程S301-S302、认证过程S303-S304，以及关联过程S305-S306：
S301、STA 102向AP 101发送探测请求(Probe Request)帧。
其中，STA 102可以使用Scanning来搜索AP，即STA搜索AP发射的SSID。当STA漫游时搜索并连接一个新的AP，STA可以在每个可用的信道上进行搜索。其中，STA搜索AP的方式有Active/Passive两种。
本申请实施例S301这里以Active Scanning搜索方式为例。STA可以依次在每个可用的信道(如13个信道)发出Probe Request帧。该Probe Request帧中携带AP的SSID。该Probe Request帧用于搜索具有上述SSID的AP。
在Passive Scanning搜索方式中，STA可以通过侦听AP定期发送的信标(Beacon)帧来发现AP。该Beacon帧可以提供AP以及AP所在本服务集(Basic Service Set，BSS)的相关信息。
S302、AP 101向STA 102返回探测响应(Probe Response)帧。
AP 101可以接收到STA 102发送的携带一个SSID的Probe Request帧。当该Probe Request帧携带的SSID与AP的SSID相同时，AP对该Probe Request帧进行应答，向STA返回Probe Response帧。
S303、STA 102向AP 101发送认证请求(Authentication Request)帧。
STA 102接收到AP 101发送的Probe Response帧后，则可以向AP 101发送Authentication Request帧，以进行STA 102的身份认证。
S304、AP 101向STA 102返回认证响应(Authentication Response)帧。
AP 101接收到Authentication Request帧后，可以对STA 102进行身份认证。在身份认证通过后，向第二设备1002返回Authentication Response帧，以指示身份认证通过。
S305、STA 102向AP 101发送关联请求(Association Request)帧。
STA 102的身份认证通过后，Wi-Fi连接的所有的准备工作就绪。此时，STA 102可以向AP 101发起正式连接请求，即Association Request帧，请求接入AP 101提供的Wi-Fi网络。
S306、AP 101向STA 102返回关联响应(Association Response)帧。
AP 101接收到Association Request帧后，可以回应Association Request帧，向STA 102发送Association Response帧。至此，Wi-Fi连接完成，STA 102可以通过AP 101提供的Wi-Fi网络进行数据传输。
可以理解，在上述建立Wi-Fi连接的过程中，可能会因为上述扫描过程、认证过程或者关联过程中任一过程出现Wi-Fi连接出错，导致Wi-Fi连接失败。本申请实施例提供一种传输控制方法，可以及时发现Wi-Fi连接出错，并进行容错处理。

在另一些实施例中，在S1504之后，第一设备与第二设备可以直接通过第二通信连接继续传输第一数据。在这种情况下，在S1504之后，本申请实施例的方第一设备与第二设备可以不执行S1505-S1507，而是直接执行S1601。具体的，如图16B所示，在S1504之后，本申请实施例的方法还可以包括S1601。
本申请实施例提供的传输控制方法，第一设备可以在发现第一通信连接出错后，通过第二通信连接向第二设备发送第一通信连接的错误信息。第一设备及时向第二设备发送第一通信连接的错误信息，可以使得第二设备可以及时感知到第一通信连接出错。并且，第一设备与第二设备可以在第一通信连接出错后，直接根据第一数据的第一断点信息，通过第二通信连接继续传输第一数据。
以第一通信连接是Wi-Fi连接，第二通信连接是蓝牙连接为例。可以理解，在第一设备与第二设备已建立了蓝牙连接的情况下，由于第一设备与第二设备重新建立Wi-Fi连接需要时间；因此，第一设备与第二设备之间通过蓝牙连接传输第一数据，可以快速完成第一数据的传输，提高第一数据的传输效率。在第一设备与第二设备未建立了蓝牙连接的情况下，由于第一设备与第二设备重新建立Wi-Fi连接需要时间，并且建立蓝牙连接所需要的时间小于建立Wi-Fi连接需要时间；因此，第一设备与第二设备之间通过蓝牙连接传输第一数据，可以快速完成第一数据的传输，提高第一数据的传输效率。
可选的，本申请实施例中，在S1504之后，第一设备或者第二设备可以根据预设策略，确定继续执行S1505-S1507，或者继续执行S1601，或者继续执行S1505-S1506和S1601。其中，第一设备或者第二设备根据预设策略，确定执行上述步骤的方法可以包括：第一设备或者第二设备根据第一数据的业务类型、第一数据的数据量和可用资源中的至少一项，确定执行上述步骤。其中，上述可用资源可以包括第一设备与第二设备可用的通信连接。
第一数据的业务类型可以指示第一数据是视频类数据、音频类数据或者文本类数据等。不同业务类型的数据对时延的要求不同。例如，当用户使用Wi-Fi网络观看视频的过程中，上述第一数据是视频类数据。为了保证用户观看视频时的用户体验，视频类数据对时延的要求一般较高。例如，视频类数据对时延的要求高于文本类数据对时延的要求。因此，当第一数据是视频类数据时，为了保证视频类数据的连续不中断传输，在S1504之后，第一设备与第二设备可以直接执行S1601，根据第一数据的第一断点信息，通过第二通信连接继续传输第一数据。
或者，当第一数据是视频类数据时，为了保证视频类数据的连续不中断传输，在S1504之后，第一设备与第二设备可以执行S1505-S1506和S1601。即第一设备与第二设备可以在重新建立Wi-Fi连接的同时，通过蓝牙连接传输该视频类数据。
当第一数据对时延的要求较低时，第一设备与第二设备则可以在重新建立Wi-Fi连接后，再通过重新建立的Wi-Fi连接继续传输该第一数据。即在S1504之后，第一设备与第二设备可以执行S1505-S1507。
可选的，考虑到第一通信连接的传输速率可能大于第二通信连接的传输速率。第 一设备和第二设备可以在第一通信连接建立成功之后，重新通过第一通信连接传输第一数据。即如图17所示，图16A所示的S1505-S1506和S1601之后，本申请实施例的方法还可以包括S1701：
S1701、在第一通信连接建立成功时，如果第一数据还未传输完，第一设备与第二设备停止通过第二通信连接继续传输第一数据，并根据第一数据的第二断点信息，通过第一通信连接继续传输第一数据。
可选的，S1701可以替换为：在第一通信连接建立成功时，如果第一数据还未传输完，且第一通信连接的传输速率高于第二通信连接的传输速率，第一设备与第二设备停止通过第二通信连接继续传输第一数据，并根据第一数据的第二断点信息，通过第一通信连接继续传输第一数据。
其中，上述第二断点信息可以是第一设备与第二设备通过上述第二通信连接传输的。第二断点信息用于指示在通过第二通信连接传输第一数据的过程中，第一设备与第二设备已经正确传输的数据的截止位置。
例如，基于上述实例，当第一设备与第二设备重新建立Wi-Fi连接后，上述视频类数据还未传输完，第一设备与第二设备则可以停止通过蓝牙连接传输该视频类数据。并且，第一设备与第二设备可以根据该视频类数据的第二断点信息，通过Wi-Fi连接继续传输视频类数据。
可选的，在第一通信连接建立成功时，如果第一数据还未传输完，终端可以判断第一数据中、还未传输完的数据量是否大于预设数据量阈值。当还未传输完的数据量大于预设数据量阈值时，终端可以停止通过第二通信连接继续传输第一数据，并通过第一通信连接继续传输第一数据。当还未传输完的数据量小于或者等于预设数据量阈值时，终端可以继续通过第二通信连接传输第一数据。其中，第一数据的数据量可以指示第一数据的大小。当第一数据的数据量较小时，第一设备和第二设备可以通过上述蓝牙设备传输该第一数据，直至第一数据传输完。即使Wi-Fi连接重新建立，也不需要通过重新建立的Wi-Fi连接传输该第一数据。
上述可用资源可以包括第一设备与第二设备可用的通信连接。例如，当第一设备与第二设备除上述第一通信连接(如Wi-Fi连接)之外，没有其他的可用通信连接，或者无法建立其他的可用通信连接时，第一设备与第二设备则可以在重新建立Wi-Fi连接后，再通过重新建立的Wi-Fi连接继续传输该第一数据。即在S1504之后，第一设备与第二设备可以执行S1505-S1507。
可选的，本申请实施例中，还可以由用户决定在S1504之后，第一设备与第二设备继续执行S1505-S1507、S1601或者S1505-S1506和S1601。
在一种实现方式中，可以由第一设备的用户决定在S1503之后，第一设备与第二设备继续执行S1505-S1507、S1601或者S1505-S1506和S1601。第一设备响应于发现第一通信连接出错，可以在执行S1503的同时，显示第二界面。第二界面中包括第一确认信息。第一确认信息用于指示第一通信连接出错，并请求用户确认“重新建立第一通信连接，然后通过重新建立的第一通信连接传输第一数据”或者“通过第二通信连接传输第一数据”。
例如，假设第一设备是手机400，第一通信连接是Wi-Fi连接，第二通信连接是 蓝牙连接。手机400响应于发现Wi-Fi连接出错，可以在执行S1503的同时，显示图18所示的第二界面1801。第二界面1801中包括第一确认信息1802。第一确认信息1802可以为“Wi-Fi连接出错！请确认在重新建立Wi-Fi连接后，通过重新建立的Wi-Fi连接传输第一数据，还是通过蓝牙连接传输第一数据？”。
在另一种实现方式中，可以由第二设备的用户决定在S1504之后，第一设备与第二设备继续执行S1505-S1507、S1601或者S1505-S1506和S1601。第二设备响应于接收到第一通信连接的错误信息，可以显示第二界面。第二界面中包括第一确认信息。第一确认信息用于指示第一通信连接出错，并请求用户确认“重新建立第一通信连接，然后通过重新建立的第一通信连接传输第一数据”或者“通过第二通信连接传输第一数据”。例如，假设第二设备是手机400，第一通信连接是Wi-Fi连接，第二通信连接是蓝牙连接。手机400接收到Wi-Fi连接的错误信息，可以显示图18所示的第二界面1801。第二界面1801中包括第一确认信息1802。第一确认信息1802可以为“Wi-Fi连接出错！请确认在重新建立Wi-Fi连接后，通过重新建立的Wi-Fi连接传输第一数据，还是通过蓝牙连接传输第一数据？”。手机400响应于用户对图18所示的“重新建立Wi-Fi连接，然后通过重新建立的Wi-Fi连接传输第一数据”选项的选择操作，可以执行S1505-S1507。手机400响应于用户对图18所示的“通过蓝牙连接传输第一数据”选项的选择操作，可以执行S1505-S1506和S1601，或者，可以执行S1601。
可选的，如果用户选择了“通过蓝牙连接传输第一数据”，那么在Wi-Fi连接重新建立成功时，如果第一数据还未传输完，手机400还可以显示第四界面1901。第四界面1901中包括第二确认信息1902。第二确认信息1902用于指示Wi-Fi连接重新建立成功，是否通过重新建立的Wi-Fi连接继续传输数据。手机400响应于用户对图19所示的“是”按钮的点击操作，可以停止通过蓝牙连接传输第一数据，并根据第一数据的第二断点信息，通过Wi-Fi连接继续传输第一数据。手机400响应于用户对图19所示的“否”按钮的点击操作，可以继续通过蓝牙连接传输第一数据。
需要说明的是，第一设备和第二设备可以基于蓝牙协议，通过第一设备与第二设备之间的蓝牙连接，传输上述第一数据。其中，第一设备和第二设备基于蓝牙协议，通过蓝牙连接传输第一数据的具体方式，可以参考第一设备和第二设备基于蓝牙协议，通过蓝牙连接传输Wi-Fi连接的错误信息的方法，本申请实施例这里不予赘述。
本申请实施例提供一种传输控制方法，不仅可以提高建立第一通信连接的效率，还可以提高第一数据的传输效率。并且，第一设备或者第二设备还可以响应于用户对第一数据的传输方式的选择，通过用户选择的通信连接完成第一数据的传输。这样，可以提高设备与用户的交互性能。
