具体实施方式
下面结合附图描述本申请实施例。
本申请实施例提供的数据发送方法，可以适用于终端设备同时与多个设备进行Wi-Fi通信的场景。示例性的，图1为本申请实施例适用的应用场景的一种示意图。如图1所示，手机A可以同时与路由器B和投屏设备C进行Wi-Fi通信。示例性的，手机A与路由器B进行Wi-Fi通信时，手机A可以工作在STA模式，路由器B工作在AP模式，AP通过管理控制STA从而组成无线网络，主要用于上网等应用场景。其中，AP模式可以提供无线接入服务，允许其它无线设备接入，提供数据访问，一般的无线路由/网桥工作在该模式下。AP和AP之间允许相互连接。STA模式类似于无线终端，STA本身并不接受无线的接入，它可以连接到AP，一般无线网卡即工作在该模式。手机A与投屏设备C可以进行Wi-Fi P2P通信，手机A和投屏设备C均工作在Wi-Fi P2P模式。Wi-Fi P2P也称为Wi-Fi Direct，可以在没有AP的情况下实现两个设备之间的直接通信，主要用于文件传输、数据传输等应用场景。常见的终端设备，例如手机可以在不同的场景下可以充当不同的角色，例如，在通过路由器等热点上网时，可以充当为STA；在热点分享的时候，也可以充当AP；在P2P通信的时候，可以充当其中一端。
需要说明，图1并不对手机A与多个设备同时进行Wi-Fi通信时的工作模式形成限定。
需要说明，本申请实施例对终端设备通过Wi-Fi通信实现的业务不做限定。例如，在图1中，手机A与路由器B无线连接后，手机A可以运行聊天应用程序(application，APP)、浏览器APP和邮件APP。手机A通过运行聊天APP可以实现发送或接收文字信息、或者实现用户的语音通话，或者实现用户的视频通话。手机A通过运行浏览器APP可以实现用户浏览网页或者观看视频。手机A通过运行邮件APP可以实现发送或接收邮件。手机A通过与投屏设备C进行Wi-Fi P2P通信可以实现投屏业务，手机A的屏幕显示的内容可以在投屏设备C上投屏显示。又例如，在另一种实现方式中，手机A与投屏设备C之间可以进行文件分享业务。
需要说明，本申请实施例对终端设备的名称和类型不做限定，对终端设备同时进行Wi-Fi通信的其他设备的数量和类型不做限定。终端设备也可以称为电子设备。目前，一些终端设备的举例为：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。
终端设备同时与多个设备进行Wi-Fi通信时，对终端设备的工作频段和工作信道不做限定。目前，终端设备可以工作在三种模式：单频单发(single band single concurrent，SBSC)、双频双发(dual band dual concurrent，DBDC)和双频自适应并发(dual band adaptive concurrent，DBAC)。下面结合图2～图4进行说明。
1、SBSC
在SBSC模式中，终端设备可以工作在单个频段的同一个信道上。示例性的，如图2所示，手机A与路由器B进行Wi-Fi通信时，使用5GHz频段中的信道149。手机A与投屏设备C进行Wi-Fi P2P通信时，也使用5GHz频段中的信道149。由于手机A工作在单个频段的同一个信道，因此，手机A可以通过时分复用射频资源，在某一时刻与路由器B通信或者与投屏设备C通信，时延性能较差。比如，手机A在T1时刻向路由器B发送聊天APP相关的报文，在T2时刻向投屏设备C发送投屏业务的报文。
2、DBDC
在DBDC模式中，终端设备可以工作在不同的频段上，或者工作在单个频段的不同信道上。手机A可以通过频分复用射频资源，在某一时刻，手机A可以同时与路由器B通信以及与投屏设备C通信，时延性能较好。
可选的，在一种实现方式中，如图3所示，手机A使用2.4GHz频段与路由器B进行Wi-Fi通信，使用5GHz频段与投屏设备C进行Wi-Fi P2P通信。
可选的，在另一种实现方式中，如图4所示，手机A使用5GHz频段的信道36与路由器B进行Wi-Fi通信，使用5GHz频段的信道149与投屏设备C进行Wi-Fi P2P通信。
3、DBAC
在DBAC模式中，终端设备可以工作在单个频段的不同信道上。示例性的，可以参见图4，手机A使用5GHz频段的信道36与路由器B进行Wi-Fi通信，使用5GHz频段的信道149与投屏设备C进行Wi-Fi P2P通信。手机A可以通过时分复用射频资源，在某一时刻与路由器B通信或者与投屏设备C通信。
下面结合图5～图7对终端设备工作在SBSC、DBDC或DBAC时适用的结构进行示例性说明。图5～图7的区别在于终端设备包括的Wi-Fi模块和射频模块的数量不同。如图5所示，终端设备可以包括应用程序处理模块11、Wi-Fi模块12和射频模块13。如图6所示，终端设备可以包括应用程序处理模块11、第一Wi-Fi模块121、第二Wi-Fi模块122、第一射频模块131和第二射频模块132。如图7所示，终端设备可以包括应用程序处理模块11、第一Wi-Fi模块121、第二Wi-Fi模块122和射频模块13。其中，应用程序处理模块可以用于对终端设备安装的上层应用程序相关的第一数据进行处理。Wi-Fi模块可以用于根据无线局域网(wireless local area networks，WLAN)协议对第二数据进行处理，本申请实施例对WLAN协议不做限定，例如，电气和电子工程师协会(institute of electrical and electronics engineers，IEEE)802系列协议。射频模块可以用于发送或接收第三数据。本申请实施例对第一数据、第二数据和第三数据的具体内容不做限定，例如，可以包括上层应用程序处理的业务报文。可以理解的是，终端设备包括的功能模块，可以为硬件和/或软件模块。
终端设备工作在SBSC模式时，结构可以参见图5～图7。结合图1，可选的，在一种实现方式中，手机A可以包括1个射频模块，例如图5或图7中的射频模块13，手机A时分复用射频模块13与路由器B通信或者与投屏设备C通信。如果Wi-Fi天线有多个，Wi-Fi天线被1个射频模块使用，可以实现多输入多输出(multi-input multi-output，MIMO)，提高信道容量和频谱效率，例如，2*2Wi-Fi MIMO。可选的，在另一种实现方式中，手机A可以包括2个射频模块，例如图6中的射频模块131和射频模块132，手机A时分复用 射频模块131和射频模块132，实现与路由器B通信或者与投屏设备C通信。此时，Wi-Fi天线被射频模块131和射频模块132分别使用，射频模块131和射频模块132可以共同实现2*2Wi-Fi MIMO。
可选的，在一种实现方式中，手机A可以包括1个Wi-Fi模块，例如图5中的Wi-Fi模块12，手机A与路由器B之间的业务以及手机A与投屏设备C之间的业务复用Wi-Fi模块12进行处理。可选的，在另一种实现方式中，手机A可以包括2个Wi-Fi模块，例如图6或图7中的第一Wi-Fi模块121和第二Wi-Fi模块122，手机A与路由器B之间的业务以及手机A与投屏设备C之间的业务可以分别通过一个Wi-Fi模块进行处理。比如，第一Wi-Fi模块121用于处理手机A与路由器B之间的业务，第二Wi-Fi模块122用于处理手机A与投屏设备C之间的业务。
终端设备工作在DBDC模式时，结构可以参见图6。可选的，在一种实现方式中，结合图1和图3，图6中的第一Wi-Fi模块121和第一射频模块131可以工作在2.4GHz频段，用于实现手机A与路由器B之间的业务。第二Wi-Fi模块122和第二射频模块132可以工作在5GHz频段，用于实现手机A与投屏设备C之间的业务。可选的，在另一种实现方式中，结合图1和图4，图6中的第一Wi-Fi模块121和第一射频模块131可以工作在5GHz低频段，用于实现手机A与路由器B之间的业务。第二Wi-Fi模块122和第二射频模块132可以工作在5GHz频段高频段，用于实现手机A与投屏设备C之间的业务。
在DBDC模式中，Wi-Fi天线被2个射频模块分别使用，SBSC中的2*2Wi-Fi MIMO模式会退化为2.4GHz 1*1+5GHz 1*1模式，或者，退化为5GHz 1*1+5GHz 1*1模式，或者，退化为2.4GHz 1*1+2.4GHz 1*1模式，损失了MIMO性能。
终端设备工作在DBAC模式时，结构可以参见图7。结合图1和图4，手机A可以时分复用射频模块13与路由器B通信或者与投屏设备C通信。图7中的第一Wi-Fi模块121可以工作在5GHz低频段，用于实现手机A与路由器B之间的业务。第二Wi-Fi模块122可以工作在5GHz频段高频段，用于实现手机A与投屏设备C之间的业务。
在实际应用中，终端设备可以采用SBSC、DBDC或DBAC中的至少一种。例如，终端设备可以根据终端设备的类型、终端设备的软硬件结构、终端设备预先配置的模式、终端设备实现的业务的类型等因素选择不同的模式。其中，对于SBSC模式，由于多个Wi-Fi天线可以工作在同频同信道实现MIMO，因此提高了信道容量和频谱效率。但是，也因为时分复用射频模块发送数据，导致高优先级的业务得不到及时的调度，数据发送时延增大，业务的服务质量(quality of service，QoS)无法得到保证。
下面结合图8，对终端设备工作在SBSC模式时发送业务报文进行示例性说明。
如图8所示，手机A工作在SBSC模式。手机A与路由器B无线连接后，手机A响应于用户的指令可以运行聊天APP、浏览器APP和邮件APP。聊天APP涉及语音业务报文和视频业务报文。例如，用户A使用聊天APP向用户B发送语音短消息，相应的，手机A获取用户A输入的音频信号，通过运行聊天APP可以生成语音业务报文。又例如，用户A使用聊天APP与用户B视频通话，相应的，手机A获取用户A通过麦克风输入的音频信号，通过摄像头可以获取用户A的图像，通过运行聊天APP可以生成视频业务报文。浏览器APP涉及网页业务报文。例如，用户A使用浏览器APP浏览网页，相应的， 手机A通过运行浏览器APP可以生成网页业务报文。邮件APP涉及邮件业务报文。例如，用户A使用邮件APP向用户C编辑发送邮件，相应的，手机A通过运行邮件APP可以生成邮件业务报文。手机A与投屏设备C进行Wi-Fi P2P连接后，手机A可以通过运行投屏APP或者手机系统自带的系统应用生成投屏业务报文。
手机A生成业务报文后，业务报文随机到达Wi-Fi芯片。手机A获取调度前的报文队列，并根据该报文队列发送业务报文。如图8所示，调度前的报文队列中包括的报文是按照报文到达顺序排列的。为了便于说明，对该报文队列中的各个报文进行编号，数字越小表示报文先到达，数字越大表示报文后到达。假设，调度前的报文队列中包括13个报文，编号为0～12，报文0最先到达，报文12最后到达。其中，报文0、9为视频业务报文，报文1、5、10为语音业务报文，报文4、7为网页业务报文，报文6为邮件业务报文，报文2、3、8、11、12为投屏业务报文。手机A根据调度前的报文队列中各个报文的排列顺序依次发送报文。报文发送顺序与调度前的报文队列中报文的排列顺序相同，即，先发送报文0，最后发送报文12。
可见，当终端设备工作在SBSC模式时，终端设备采用时分复用的方式发送数据，并根据报文到达顺序依次发送，导致高优先级的业务得不到及时的调度。例如，投屏业务报文的优先级较高，但是当到达时间晚于其他类型的报文时，无法及时发送，时延增大，导致业务的QoS无法得到保证。
本申请实施例提供一种数据发送方法，适用于终端设备同时与多个设备进行Wi-Fi通信且终端设备工作在SBSC模式的场景。终端设备可以获取业务报文的优先级，根据业务报文的优先级将业务报文划分至不同的队列中。其中，终端设备可以在运行上层应用程序时为业务报文添加优先级。每个队列对应有权重值，权重值用于确定终端设备每次发送该队列中业务报文的个数。终端设备根据多个队列分别对应的权重值依次发送每个队列中的业务报文。由于终端设备发送业务报文时考虑了业务报文的优先级，使得高优先级的业务报文得到了优先发送的机会，在SBSC模式中，既获得了Wi-Fi多天线同时工作的增益，又降低了高优先级业务的传输时延，保证了业务的QoS要求。
需要说明的是，本申请实施例中的业务报文可以通过Wi-Fi通信进行传输，对业务报文的名称不做限定，例如，也可以称为业务数据、业务数据包、报文等。为了便于说明，本申请实施例以业务报文为例进行说明。
需要说明的是，本申请实施例对队列的个数不做限定。队列的个数可以为大于1的任意整数。
需要说明的是，本申请实施例对每个队列的权重值的取值不做限定。不同队列的权重值的取值可以相同，也可以不同。所有队列对应的权重值中至少具有两种取值。举例说明。在一个示例中，队列为4个，标记为队列1～4，对应的权重值分别为4、2、1、1。权重值可以为终端设备每次发送该队列中业务报文的个数。那么，终端设备可以每次发送队列1中的4个报文、队列2中的2个报文、队列3中的1个报文或队列4中的1个报文。在另一个示例中，队列为3个，标记为队列1～3，对应的权重值分别为3、2、1。权重值可以为终端设备每次发送队列中业务报文的个数与预设个数之间的比值。例如，预设个数为1，那么，终端设备可以每次发送队列1中的3个报文、队列2中的2个报文或队列3中的1 个报文。又例如，预设个数为2，那么，终端设备可以每次发送队列1中的6(权重值3×预设个数2)个报文、队列2中的4(2×2)个报文或队列3中的2(1×2)个报文。
需要说明的是，终端设备每次发送队列中的业务报文的个数，是指可以发送的最大个数。在实际发送中，如果队列中剩余的业务报文的个数较多，大于或等于所述最大个数，则终端设备可以发送队列中该最大个数的业务报文。如果队列中剩余的业务报文的个数较少，小于所述最大个数，则终端设备可以发送队列中所有剩余的业务报文。例如，根据权重值确定终端设备每次发送队列1中业务报文的个数为6。那么，当队列1中剩余报文个数为7个时，终端设备可以发送6个报文，当队列1中剩余报文个数为5个时，终端设备可以发送5个报文。
需要说明的是，本申请实施例对队列与业务报文的优先级之间的对应关系不做限定。可选的，队列的个数与优先级的个数可以相同，队列与优先级之间可以一一对应。例如，队列为4个，标记为队列1～4。业务报文的优先级为4种，标记为优先级1～4，优先级1最高，优先级4最低。优先级1～4的业务报文可以分别划分至队列1～4中。可选的，队列的个数可以小于优先级的个数，存在至少1个队列，该队列与至少两种优先级对应。例如，队列为3个，标记为队列1～3。业务报文的优先级为5种，标记为优先级1～5，优先级1最高，优先级5最低。在一种实现方式中，优先级1的业务报文可以划分至队列1中、优先级2～3的业务报文可以划分至队列2中、优先级4～5的业务报文可以划分至队列3中。在另一种实现方式中，优先级1的业务报文可以划分至队列1中、优先级2的业务报文可以划分至队列2中、优先级3～5的业务报文可以划分至队列3中。其中，高优先级对应的队列的权重值大于或等于低优先级队列的权重值。
需要说明的是，本申请实施例对业务报文的类型与业务报文的优先级之间的对应关系不做限定。可选的，业务报文的类型的个数与优先级的个数可以相同，业务报文的类型与优先级之间可以一一对应。例如，业务报文的类型为4种，标记为类型1～4。业务报文的优先级为4种，标记为优先级1～4，优先级1最高，优先级4最低。业务报文的类型1～4与业务报文的优先级1～4一一对应，比如，业务报文的类型1与业务报文的优先级1相对应。可选的，业务报文的类型的个数大于优先级的个数，存在至少1种优先级，该优先级与至少两种业务报文的类型相对应。例如，业务报文的优先级为3个，标记为优先级1～3。业务报文的类型为5种，标记为类型1～5。在一种实现方式中，业务报文的类型1对应优先级1、业务报文的类型2～3对应优先级2、业务报文的类型4～5对应优先级3。在另一种实现方式中，业务报文的类型1对应优先级1、业务报文的类型2对应优先级2、业务报文的类型3～5对应优先级3。
需要说明的是，本申请实施例对业务报文的类型不做限定，根据终端设备的设置或者上层应用程序的类型可以有不同的实现方式。可选的，业务报文的类型可以包括但不限于下列中的至少一项：语音业务报文、视频业务报文、网页业务报文、邮件业务报文、游戏业务报文、投屏业务报文或文件共享业务报文。
需要说明的是，本申请实施例对上层应用程序与业务报文类型之间的对应关系不做限定。一个应用程序可以涉及至少一种类型的业务报文，例如，如图8所示，聊天APP可以涉及语音业务报文和视频业务报文。
需要说明的是，本申请实施例提供的数据发送方法，一种应用场景可以为：终端设备 上安装有多种类型的应用程序，还安装有系统自带的应用程序。由于应用程序的开发者不同、版本不同，有些应用程序支持为业务报文添加优先级，有些应用程序不支持为业务报文添加优先级。相应的，终端设备通过运行不同的应用程序，可能为业务报文添加优先级，也可能没有为业务报文添加优先级。在本申请实施例中，业务报文不具有优先级也可以理解为具有最低等级的优先级。例如，队列为3个，标记为队列1～3。业务报文的优先级为3种，标记为优先级1～3，优先级1最高，优先级3最低。在一种实现方式中，优先级1的业务报文可以划分至队列1中、优先级2的业务报文可以划分至队列2中、优先级3的业务报文以及不具有优先级的业务报文可以划分至队列3中。在另一种实现方式中，优先级1的业务报文可以划分至队列1中、优先级2～3的业务报文可以划分至队列2中、不具有优先级的业务报文可以划分至队列3中。
下面结合图9～图13，对终端设备采用本申请实施例提供的数据发送方法后发送业务报文进行示例性说明。在图9～图13中，业务报文的类型和调度前的报文队列参见图8中的相关描述，此处不再赘述。在各个示例中，队列的权重值直接指示终端设备每次发送队列中业务报文的个数。
可选的，在一个示例中，如图9所示，业务报文的优先级为5种，标记为优先级1～5，优先级1最高，优先级5最低。投屏业务报文、视频业务报文、语音业务报文、网页业务报文、邮件业务报文的优先级依次为优先级1～5。队列为5个，标记为队列1～5。手机A可以获取调度前的报文队列中各个报文的优先级，并根据业务报文的优先级将业务报文划分至不同的队列中。具体的，优先级1～5的业务报文分别划分至队列1～5中。队列1中包括报文2、3、8、11、12，均为投屏业务报文。队列2中包括报文0、9，均为视频业务报文。队列3中包括报文1、5、10，均为音频业务报文。队列4中包括报文4、7，均为网页业务报文。队列5中包括报文6，为邮件业务报文。队列1～5的权重值分别为5、4、3、2、1，即，手机A可以每次发送队列1中的5个报文、队列2中的4个报文、队列3中的3个报文、队列4中的2个报文或队列5中的1个报文。手机A根据多个队列分别对应的权重值依次发送每个队列中的业务报文，报文发送顺序(用数字编号表示)依次为：2、3、8、11、12、0、9、1、5、10、4、7、6。可见，由于终端设备发送业务报文时考虑了业务报文的优先级，使得高优先级的业务报文得到了优先发送的机会，比如，手机A优先发送投屏业务报文且每次发送5个，使得终端设备工作在SBSC模式时降低了高优先级业务的传输时延，保证了业务的QoS要求。而且，低优先级的业务报文虽然发送的占比少，比如，邮件业务报文位于队列5中，手机A每次发送1个邮件业务报文，但是，低优先级的业务报文也不会完全得不到发送的机会，低优先级业务的功能并不会受到影响。
可选的，在另一个示例中，如图10所示，业务报文的优先级为4种，标记为优先级1～4，优先级1最高，优先级4最低。队列为4个，标记为队列1～4。优先级1～4的业务报文分别划分至队列1～4中。本示例与图9所示示例的区别在于：在本示例中，1个优先级可以对应多种类型的业务报文，例如，网页业务报文和邮件业务报文的优先级均为优先级4。手机A对业务报文分类后，队列1～3与图9中的队列1～3相同，队列4中包括报文4、6、7，包括网页业务报文和邮件业务报文。队列1～4的权重值分别为4、2、1、1。手机A根据多个队列分别对应的权重值依次发送每个队列中的业务报文，第一轮发送的报文(用 数字编号表示)包括：2、3、8、11、0、9、1、4，各个队列中剩余的报文包括：队列1中的报文12，队列3中的报文5、10，以及队列4中的报文6、7。手机A根据多个队列分别对应的权重值继续发送每个队列中的业务报文，第二轮发送的报文包括：12、5、6，第三轮发送的报文包括：10、7。最终，报文发送顺序依次为：2、3、8、11、0、9、1、4、12、5、6、10、7。
可选的，在又一个示例中，如图11所示，业务报文的优先级为5种，标记为优先级1～5，优先级1最高，优先级5最低。队列为4个，标记为队列1～4。本示例与图9所示示例的区别在于：在本示例中，1个队列可以对应多种业务报文的优先级，例如，优先级4和5的业务报文可以划分至队列4中。手机A对业务报文分类后，队列1～3与图9中的队列1～3相同，队列4中包括报文4、6、7，包括网页业务报文和邮件业务报文。队列1～4的权重值分别为4、2、1、1。手机A根据多个队列分别对应的权重值依次发送每个队列中的业务报文，报文发送顺序与图10相同，此处不再赘述。
可选的，在又一个示例中，如图12所示，业务报文的优先级为3种，标记为优先级1～3，优先级1最高，优先级3最低。投屏业务报文的优先级为优先级1、视频业务报文和语音业务报文的优先级为优先级2、邮件业务报文的优先级为优先级3。队列为3个，标记为队列1～3。本示例与图9～11所示示例的区别在于：在本示例中，部分业务报文不具有优先级，例如，网页业务报文不具有优先级。在本示例中，优先级1的业务报文可以划分至队列1中，优先级2的业务报文可以划分至队列2中，优先级3和无优先级的业务报文可以划分至队列3中，队列3的权重值最小。手机A对业务报文分类后，队列1中包括报文2、3、8、11、12，均为投屏业务报文。队列2中包括报文0、1、5、9、10，包括语音业务报文和视频业务报文。队列3中包括报文4、6、7，包括网页业务报文和邮件业务报文。队列1～3的权重值分别为4、2、1。手机A根据多个队列分别对应的权重值依次发送每个队列中的业务报文，第一轮发送的报文(用数字编号表示)包括：2、3、8、11、0、1、4，第二轮发送的报文包括：12、5、9、6，第三轮发送的报文包括：10、7。
可选的，在又一个示例中，如图13所示，业务报文的优先级为4种，标记为优先级1～4，优先级1最高，优先级4最低。队列为4个，标记为队列1～4。本示例与图12所示示例的区别在于：在本示例中，将无优先级的业务报文单独划分至1个队列中，该队列的权重值为所有队列的权重值中的最小值，例如，划分至队列4中。手机A对业务报文分类后，队列1中包括报文2、3、8、11、12，均为投屏业务报文。队列2中包括报文0、9，均为视频业务报文。队列3中包括报文1、5、6、10，包括语音业务报文和邮件业务报文。队列4中包括报文4、7，包括网页业务报文，无优先级。队列1～4的权重值分别为4、2、2、1。手机A根据多个队列分别对应的权重值依次发送每个队列中的业务报文，第一轮发送的报文(用数字编号表示)包括：2、3、8、11、0、9、1、5、4，第二轮发送的报文包括：12、6、10、7。
下面以具体的实施例对本申请的技术方案进行详细说明。
图14为本申请实施例提供的数据发送方法的一种流程图。本实施例提供的数据发送方法，执行主体可以为终端设备。如图14所示，本实施例提供的数据发送方法，可以包括：
S1401、获取待发送的第一业务报文。
其中，第一业务报文为可以通过Wi-Fi通信传输的业务报文，可以为经过上层应用程序处理后传输至底层Wi-Fi芯片的业务报文。
本申请实施例对上层应用程序的开发者和功能不做限定。可选的，应用程序可以为终端设备系统自带的应用程序，例如：浏览器、邮件应用程序或智能家居类应用程序等，终端设备的类型不同，系统自带的应用程序可以不同。可选的，应用程序可以为用户在终端设备上安装的由第三方开发的应用程序，例如：浏览器、聊天类APP、视频类APP或文件分享类APP等。
S1402、判断第一业务报文是否具有优先级。
其中，第一业务报文可能具有优先级，也可能不具有优先级，与处理第一业务报文的上层应用程序相关。比如，终端设备系统自带的部分应用程序可能支持为业务报文添加优先级，第一业务报文具有优先级。由第三方开发的部分应用程序可能不支持为业务报文添加优先级，第一业务报文不具有优先级。
如果第一业务报文具有优先级，则执行S1403。如果第一业务报文不具有优先级，则执行S1404。
当第一业务报文具有优先级时，本申请实施例对第一业务报文携带优先级的方式不做限定。
可选的，在一种实现方式中，优先级可以携带在业务报文的字段中。可选的，该字段可以为业务报文中的原有字段，可选的，优先级可以复用该原有字段中的部分比特位，或者，占用该原有字段中的保留比特位。可选的，该字段可以为业务报文中的保留字段。可选的，该字段可以为业务报文中的新增字段。
下面通过表1对业务报文的格式和业务报文中携带优先级的字段进行示例性说明，但表1并不对此形成限定。表1示出了802.3协议中规定的报文格式，通过复用字段“Q-Tag”中的“用户优先级”部分，第一业务报文可以携带优先级。在本申请实施例中，预先建立有优先级与队列之间的对应关系。

S1403、若第一业务报文具有优先级，则根据预设的M个优先级与N个队列之间的对应关系，将第一业务报文划分至第一业务报文的优先级对应的目标队列中。
其中，M和N为大于1的整数，M大于等于N。队列设置有权重值，权重值用于确定终端设备每次发送该队列中业务报文的个数。M个优先级中第一优先级对应的队列的权重值大于或等于第二优先级对应的队列的权重值，第一优先级高于第二优先级。
其中，本申请实施例对M和N的具体取值不做限定，对M个优先级与N个队列之间的对应关系不做限定，对每个队列的权重值的具体取值不做限定。示例性的，可以参见上面图9～图13的相关描述，此处不再赘述。
在本申请实施例中，N个队列也具有优先级，高优先级队列的权重值大于或等于低优先级队列的权重值。对于M个优先级中高优先级对应的队列A和M个优先级中低优先级对应的队列B，队列A的优先级高于队列B的优先级。终端设备在发送业务报文时，将优先发送高优先级队列中的业务报文，后发送低优先级队列中的业务报文。举例说明。在一个示例中，如图9所示，M个优先级包括优先级1～5，优先级1～5分别对应队列1～5，队列1～5的优先级逐渐降低，队列1的优先级最高，队列5的优先级最低。队列1～5的权重值分别为5、4、3、2、1，高优先级队列的权重值大于低优先级队列的权重值。在另一个示例中，如图11所示，M个优先级包括优先级1～5。优先级1对应队列1、优先级2对应队列2、优先级3对应队列3、优先级4～5对应队列4，队列1～4的优先级逐渐降低，队列1的优先级最高，队列4的优先级最低。队列1～4的权重值分别为4、2、1、1。其中，队列3的优先级高于队列4的优先级，队列3的权重值与队列4的权重值相同，终端设备在发送业务报文时，将优先发送队列3中的业务报文，后发送队列4中的业务报文。
S1404、若第一业务报文不具有优先级，则将第一业务报文划分至第一队列中。其中，第一队列的权重值为N个队列的权重值中的最小值。
具体的，对于不具有优先级的业务报文，终端设备将该业务报文划分至优先级最低的第一队列中。
可选的，在一种实现方式中，第一队列中的业务报文可以包括不具有优先级的业务报文以及M个优先级中低优先级的业务报文。例如，如图12所示，优先级3和不具有优先级的业务报文都被划分至队列3中。
可选的，在另一种实现方式中，第一队列中的业务报文可以包括不具有优先级的业务 报文。例如，如图13所示，不具有优先级的业务报文都被划分至队列4中。
S1405、按照N个队列的优先级从高到低的顺序，依次根据每个队列的权重值发送该队列中的业务报文。
具体的，按照N个队列的优先级从高到低的顺序，对于优先级最高的第一个队列，根据该队列的权重值确定终端设备每次可以发送的业务报文的个数(标记为Q)，并判断该队列中当前业务报文的个数是否大于或等于Q。如果该队列中当前业务报文的个数大于或等于Q，则终端设备发送该队列中的Q个业务报文。如果该队列中当前业务报文的个数小于Q，则终端设备发送该队列中的所有业务报文。然后，对于优先级低于第一个队列的第二个队列，按照第一个队列的处理方式发送第二个队列中的业务报文，以此类推，直至发送优先级最低的最后一个队列中的业务报文。之后，终端设备按照N个队列的优先级从高到低的顺序循环发送N个队列中的业务报文。示例性的，业务报文的发送过程可以参见图9～图13中的相关描述。
可见，本实施例提供的数据发送方法，可以适用于终端设备同时与多个设备进行Wi-Fi通信且终端设备工作在SBSC模式的场景。终端设备获取待发送的第一业务报文后，判断第一业务报文是否具有优先级。当第一业务报文具有优先级时，可以根据优先级与队列之间的对应关系，将第一业务报文划分至第一业务报文的优先级对应的目标队列中。当第一业务报文不具有优先级时，可以将第一业务报文划分至最低优先级的队列中。每个队列对应有权重值。终端设备按照多个队列的优先级从高到低的顺序，根据多个队列分别对应的权重值依次发送每个队列中的业务报文。由于终端设备发送业务报文时考虑了业务报文的优先级，高优先级的业务报文得到了优先发送的机会，在SBSC模式中，降低了高优先级业务的传输时延，保证了高优先级业务的QoS要求。而且，低优先级的业务报文虽然发送的占比少，但也不会完全得不到发送的机会，低优先级业务的功能并不会受到影响。
可选的，本实施例提供的数据发送方法，还可以包括：

需要说明的是，本申请实施例对业务报文的类型与业务报文的优先级之间的对应关系不做限定。
