一种数据传输方法及装置
本申请要求于2021年10月12日提交国家知识产权局、申请号为202111187778.4、发明名称为“一种数据传输方法及装置”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
本申请涉及通信技术领域，尤其涉及一种数据传输方法及装置。
背景技术
由于资费更低，网速更快，使得Wi-Fi上网成为很多用户的上网首选方式。Wi-Fi上网中会使用到Wi-Fi设备，Wi-Fi设备可以是接入点(access point，AP)、站点(station，STA)等包括Wi-Fi芯片的设备。
Wi-Fi网络可包括邻居感知网络(neighbor awareness networking，NAN)。NAN为设备划分了专用于传输控制信息的资源以及专用于传输数据信息的资源，设备可以使用相应资源进行通信。但是，由于现有的资源划分方式中，系统为设备划分的资源固定，导致资源利用率不高，数据传输性能低。
发明内容
本申请提供一种数据传输方法及装置，可以在邻居感知网络中提升数据传输性能。
为了实现上述目的，本申请实施例提供了以下技术方案：
第一方面，提供数据传输方法，应用于第一电子设备或能够实现第一电子设备功能的组件(比如芯片系统)，第一电子设备加入到第一集群中，第一集群所在的网络为第一网络，方法包括：确定发现窗口内存在待发送的数据帧，并在发现窗口内发送数据帧。可见，集群内的设备(比如第一电子设备)除了可以在发现窗口内交互管理帧，还可以根据业务需求，在发现窗口内交互数据帧。如此一来，一方面，能够利用发现窗口中闲置的时域资源来传输数据帧，进而能够提升时域资源的利用率，避免空闲时域资源的浪费。另一方面，由于不再局限于发现窗口结束后才能传输数据帧，则数据帧的传输时机可以提前至发现窗口内，如此，能够降低业务的时延。综上，本申请实施例的技术方案，能够综合提高数据传输性能。
在一种可能的设计中，在发现窗口内发送数据帧之前，方法还包括：确定是否满足允许第一电子设备在发现窗口内发送数据帧的第一条件；

具体实施方式
如图1所示，为本申请实施例提供的一种通信系统的结构示意图。该通信系统包括电子设备100-电子设备700。在本申请实施例中，电子设备100-电子设备700可以是支持WLAN感知协议(或称NAN协议)的设备。
支持WLAN感知协议的设备可以开启WLAN感知功能。在开启WLAN感知功能后，电子设备可以发现(discover)与其临近的邻居设备，并可以加入到邻居设备所在集群内。如图1所示，电子设备100-电子设备700可以组成集群。作为一种可能的实现方式，同一集群中的各设备共享一组NAN参数。可选的，NAN参数包括但不限于NAN集群标识(ID)。
需要说明的是，集群中的设备可以作为主(master)设备或从(non-master)设备。作为一种可能的实现方式，在该集群中，各设备之间可以通过选举，确定集群中的主设备。可选的，确定主角等级(master ranking level)值最大的设备为主设备。可以理解，对于同一个设备来说，在某些情况下，其可以是主设备，在某些情况下，其可以是从设备，设备在某个集群的角色并非固定不变。并且，可选的，主设备可以是诸如接入点一类的设备，也可以是站点一类的设备。类似的，从设备可以是诸如接入点一类的设备，也可以是站点一类的设备。
可选的，设备的主角等级值，与电量、设备的类型等一个或多个参数有关。
通常，在确定集群中的主设备后，该主设备可执行主设备对应的一系列操作。集群中的从设备，则执行从设备对应的操作。示例性的，主设备对应的操作包括但不限于：发送beacon(信标)帧，并可以在该beacon帧中携带时间同步功能(time synchronization function，TSF)时钟信息。从设备对应的操作包括但不限于：接收到来自主设备的beacon帧后，提取TSF时钟信息，并且根据TSF时钟信息，完成与主设备之间的时间同步。可选的，从设备可以根据TSF时钟信息以及本地估算的延迟(比如从天线端口接收到最后处理的本地延迟)，实现与主设备之间的时间同步。当然，从设备同步时间的方式还可以为其他，这里不做限定。
后续，图1所示集群之外的设备可以发现并加入图1所示集群。作为一种可能的实现方式，电子设备800(未在图1中示出)开启WLAN感知功能后，可搜索beacon帧，若电子设备800搜索到来自图1所示集群中主设备(比如电子设备)的beacon帧，则电子设备800可以根据该beacon帧同步到电子设备，如此一来，电子设备800加入了图1所示集群。
在本申请实施例中，诸如图1所示的集群还可以称为一个域(cluster)。其中，该集群中的设备可以包括已经和其他设备建立数据连接的设备，没有和其他设备建立 数据连接的设备。通常，建立数据连接的设备之间，可以交互数据帧和管理帧。未建立数据连接的设备之间，可以交互管理帧，不可以交互数据帧。
可选的，已建立数据连接的设备之间可组成一个岛(NAN协议中称为data cluster)。示例性的，如图1所示集群中，假设电子设备300-700同步到同一个电子设备，则电子设备300-700组成一个集群。其中，集群中的设备100和设备300之间建立了数据连接，则称设备100和设备300组成一个岛(后续，其他设备也可以加入该岛)。设备400和设备500建立数据连接，设备400和设备600建立数据连接，则设备400、设备500以及设备600可组成一个岛。设备700、设备200没有与其他设备之间建立数据连接，设备700、200并未在岛中。
通常，在时域上，同一集群内的设备根据相同的调度周期以及相同的发现窗口进行调度。其中，如图2A所示，一个调度周期通常包含一个发现窗口(discovery window，DW)，不同调度周期的发现窗口之间存在间隔GAP，GAP可用来传输数据，可称为业务时隙或工作时隙。在一些方案中，集群内的设备可以在调度周期的发现窗口内交互管理帧(数据帧之外的帧统称管理帧)，在调度周期的发现窗口之外交互数据帧。也就是说，发现窗口通常用来交互数据帧之外的管理帧，管理帧包括但不限于如下任一种或多种帧：beacon帧、周期宣告帧(period notification frame，PNF)。
作为一种可能的实现方式，主设备可以广播窗口参数。窗口参数包括发现窗口长度、调度周期、业务时隙长度中的任意两者。集群内的其他设备与主设备同步之后，按照窗口参数周期地切换到发现窗口交互管理帧。可选的，在调度周期的发现窗口内，集群内的设备可以在相同的信道上交互管理帧。在调度周期的发现窗口外，同一岛内的设备可以在相同信道上交互数据帧，不同岛的设备可以在不同信道上交互数据帧。示例性的，如图2B示出了图1所示集群中各设备的管理帧的时域位置和频域位置。其中，图1所示集群中的各设备均可以在调度周期内的发现窗口，在相同的公共信道36上传输管理帧。图2B还示出了图1所示集群中部分设备的数据帧的时域位置和频域位置。图2B是以图1所示岛1中的设备100和设备300使用信道40交互数据帧，图1所示岛2中的设备400、500、600使用信道149交互数据帧为例进行说明。
在一些方案中，集群内设备之间交互的数据帧和管理帧的时域位置和/或频域位置还可以为其他，并不局限于上述所列方式。比如，对于不同岛的设备，可以使用相同的信道交互数据帧。示例性的，岛1使用channel10交互数据帧，岛2也使用channel10交互数据帧。
上述方案中，数据帧的最快发送时机是本调度周期的非发现窗口内，仍以图2B为例，对于集群内设备来说，数据帧的最快发送时机是第一个调度周期的发现窗口结束时，即t1时刻。这样一来，有可能导致业务延迟，对于时延要较高的业务来说，业务迟延将严重影响WLAN性能，进而降低用户体验。
为了提升终端的WLAN性能，本申请实施例中，集群内的设备除了可以在发现窗口内交互管理帧，还可以根据业务需求，在发现窗口内交互数据帧。如此一来，一方面，能够利用发现窗口中闲置的时域资源来传输数据帧，进而能够提升时域资源的利用率，避免WLAN空闲时域资源的浪费。另一方面，由于不再局限于发现窗口结束后才能传输数据帧，则数据帧的传输时机可以提前至发现窗口内，如此，能够降低业务 的时延。综上，本申请实施例的技术方案，能够综合提高WLAN的传输性能。
示例性的，本申请中的电子设备可以为手机、平板电脑、个人计算机(personal computer，PC)、个人数字助理(personal digital assistant，PDA)、智能手表、上网本、可穿戴电子设备、增强现实技术(augmented reality，AR)设备、虚拟现实(virtual reality，VR)设备、车载设备、智能汽车、智能音响、机器人等，本申请对该电子设备的具体形式不做特殊限制。
本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理。“第一”、“第二”等字样可以对功能和作用基本相同的相同项或相似项进行区分。例如，第一设备和第二设备仅仅是为了区分不同的设备，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
“至少一个”是指一个或者多个，
“多个”是指两个或两个以上。
“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请的说明书以及附图中“的(英文：of)”，相应的“(英文corresponding，relevant)”和“对应的(英文：corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。

示例性的，如图5所示，示出了本申请实施例的传输方法的一个应用示例。集群内的设备除了可以在业务时隙(即GAP)交互数据帧，还可以在发现窗口内交互数据帧。与图2B所示传输方法相比，图5所示传输方法中，一方面，能够利用发现窗口中闲置的部分时域资源来传输数据帧，进而能够提升WLAN时域资源的利用率。另一方面，数据帧的传输时机可以由发现窗口结束时刻(比如图2B所示t1)提前至发现窗口内(比如图5所示t2)，如此，能够降低WLAN业务的时延。可见，本申请实施例的技术方案，能够综合提高WLAN的传输性能。
在本申请的一些实施例中，可以默认电子设备一直开WLAN传输性能增强的功能。WLAN传输性能增强，可以指在WLAN传输过程中，允许在发现窗口内传输数据帧。
或者，在另一些实施例中，电子设备中可以设置开关，用户可以通过该开关手动开启或关闭本申请实施例提供的提升电子设备WLAN传输性能的功能。例如，如图6A的(1)和图6A的(2)所示，可以在“设置”应用501的设置页面中设置有开关控件501，用于用户开启或关闭本申请实施例提供的WLAN传输增强功能(即提升数据传输性能的第一功能)。又例如，如图6B的(1)所示，响应于用户对设置应用501诸如点击操作，电子设备显示如图6B的(2)所示的设置界面，响应于用户在设置界面对WLAN开关503的诸如点击操作，电子设备显示如图6B的(3)所示的WLAN设置界面，该WLAN设置界面包括开关504，可用于开启或关闭本申请实施例的提升WLAN传输性能的功能。在接收用户的打开开关504的指令(第一指令)之后，可开启WLAN传输增强功能，

可选的，预设应用程序为低时延业务的应用，例如即时通信类应用程序、游戏应用。预设应用程序可以由电子设备设置，或由用户设置。比如，电子设备默认将某些业务类型的应用程序的WLAN传输增强功能开启。
如此一来，在检测到打开预设应用(比如视频直播软件)后，可以通过在发现窗口内及时发送该预设应用的数据帧，无需等待发现窗口结束再发送数据帧，能够保证业务的低时延，避免由于等待发现窗口结束导致的时域资源的浪费。
可选的，预设应用的预设功能包括但不限于低时延业务的功能。低时延业务的功能包括但不限于语音通话功能、视频通话功能、投屏等功能。
在本申请实施例中，第一电子设备在检测到预设场景后，可以自动开启WLAN传输性能增强功能，或提示用户开启。对于开启WLAN传输增强功能的应用程序来说，可以使用本申请实施例提供的WLAN中传输数据的方法提升该应用程序传输(比如发送和/或接收)数据帧过程中的传输性能。
示例性的，参见图7的(3)所示，用户可以通过诸如点击控件601的操作，触发手机弹出控件603。该控件可用来选择开启目标应用时，如何设置对应的WLAN传输增强功能。其中，若用户选择“开启目标应用时，自动使用WLAN传输增强功能”，则后续在手机检测到目标应用被启动后，可以使用本申请实施例的技术方案，即，若该目标应用有待发送数据帧，则可以允许在发现窗口内发送该数据帧。
可选的，电子设备还可以提供设置目标应用(或称预设应用)的入口。仍以图7的(3)为例，手机可显示控件602，若检测到用户的诸如点击控件602的操作，则手机可跳转到图7的(4)所示界面604。通过界面604，用户可接收用户输入的第二指令，设置目标应用。后续，目标应用的数据帧可在发现窗口内发送，能够降低目标应用的业务延迟。
需要说明的是，电子设备提供给用户的用于设置开启WLAN传输增强功能的应用的上述设置入口，仅是举例，设置入口(包括但不限于通过界面设置)还可以是其他。
在另一些实施例中，还可以是第一电子设备在检测到用于开启Wi-Fi功能的操作(比如打开Wi-Fi开关)后，自动开启或提示用户开启提升WLAN传输性能的功能。

实施例一
如下对本申请实施例提供的WLAN中传输数据的方法进行详细介绍，如图8所示， 该方法可以包括如下步骤：
S101、第一电子设备确定发现窗口内存在待发送数据帧。
其中，第一电子设备可以是第一集群中的主设备或从设备，这里不做限制。第一集群所在的网络为第一网络。
作为一种可能的实现方式，第一电子设备可以将上层应用程序产生的数据，存储在诸如队列等存储区域中，并在需要发送时，从队列中取出相应数据并发送。以队列为存储帧的区域为例，可选的，本申请实施例中，数据帧和管理帧可以存储在不同队列。可选的，队列可包括软件队列和硬件队列。示例性的，如图9示出了本申请实施例所使用的队列的示例。其中，第一电子设备可以将上层应用程序产生的数据帧存储到数据帧的硬件队列，在一些示例中，当硬件队列已填满数据帧，则第一电子设备将上层应用程序产生的数据帧存储到数据帧的软件队列。在一些示例中，当数据帧的软件队列也被填满，后续产生的数据帧将可能被丢弃。类似的，第一电子设备也可以将待发送的管理帧存储在管理帧对应的队列中。管理帧对应的队列也可以划分为软件队列和硬件队列，管理帧的软件队列和硬件队列的工作原理可参考数据帧的软件队列和硬件队列。
需要说明的是，发现窗口内存在待发送数据帧，可以指发现窗口对应的时间段内，数据帧队列中已存在待发送数据帧，或者，在发现窗口对应的时间段内，有新到达数据帧队列的待发送数据帧。此种情况下，第一电子设备可以执行步骤S102，即在发现窗口内发送待发送数据帧，以便提示资源利用率以及降低业务时延。
S102、第一电子设备在发现窗口内发送该待发送数据帧。
示例性的，如图10的(2)示出了本申请实施例中队列调度与发现窗口之间的关系。其中，图10中的帧1、帧2、帧3指的是数据帧。可以看出，在发现窗口内，数据帧队列的调度处理并未暂停。可选的，切换到发现窗口时不暂停数据帧的软件队列和硬件队列的调度处理。也就是说，软件队列或硬件队列中有需要发送的数据帧时，可以直接在发现窗口内调度发送该待发送数据帧。而图10的(1)所示方案(现有技术方案)中，在发现窗口内，数据帧队列被暂停调度处理，在发现窗口结束后，才恢复数据帧队列的调度处理，使得不能及时在发现窗口内发送数据帧，导致业务的时延，且浪费了发现窗口内的闲置资源。可见，相比于现有技术，本申请实施例的数据传输方法，通过允许在发现窗口中发送数据帧，不仅能够尽可能降低业务时延，还能够提升资源利用率，进而获得更高的WLAN性能。
此外，与现有技术中在发现窗口暂停队列调度处理，极大概率可能导致队列溢出，数据帧被丢弃相比，本申请实施例中，由于并未暂停数据帧的调度处理，也可以视为数据帧的调度处理没有被中断，因此，能够及时将待发送数据帧从队列中取出并发送，为队列提供更多的存储区域，进而能够降低队列溢出的概率，降低因队列溢出导致的数据帧丢弃。
示例性的，以图1中的设备200为主设备，且第一电子设备为设备200为例，若设备200确定当前的数据帧队列中有待发送的数据帧，且当前处于发现窗口内，则可以在该发现窗口及时发送该数据帧，如此，能够提升资源利用率以及降低业务时延。而现有技术中，若设备200确定当前的数据帧队列中有待发送的数据帧，且当前处于 发现窗口内，则设备200需等待该发现窗口结束后才能发送该数据帧，资源利用率较低，业务时延较大。
再示例性的，以图1中的设备100为从设备，且第一电子设备为设备100为例，若设备100确定当前的数据帧队列中有待发送的数据帧，且当前处于发现窗口(比如图10的(2)所示的发现窗口1内，则可以在该发现窗口发送待发送数据帧。若设备100确定当前的数据帧队列中有待发送的数据帧，且当前处于发现窗口之外(比如图10的(2)所示GAP1)，则可以在该GAP1内发送待发送数据帧。也就是说，设备在确定数据帧队列中存在待发送数据帧的情况下，可根据预设策略直接发送待发送数据帧，无需根据当前是否处于发现窗口内判断是否允许发送数据帧。
可选的，可以通过Wi-Fi MAC帧格式中的2bit Type字段区分数据帧和管理帧。可选的，10表示数据帧(Data frame)、00表示Management frame、01表示Control frame、11表示Extension frame(扩展帧)。Management frame、Control frame、Extension frame可统称为管理帧。图11示例性的示出了一种MAC帧格式。其中，加粗方框中的类型字段可用来区分数据帧和管理帧。可以理解，这里仅是用于区分数据帧和管理帧的一种举例方式，在实际实现时，还可以利用其他帧格式的其他任意比特的字段，限于篇幅，本申请实施例不再穷举所有可能情况。
实施例二
本申请实施例还提供一种数据传输方法，图12示出了实施例二的示例性流程。如图12所示，在实施例一的步骤S102之前，可以执行步骤S201、判断是否允许在发现窗口发送数据帧，若允许在发现窗口内发送数据帧，则第一电子设备执行步骤S102，若不允许(禁止)在发现窗口内发送数据帧，则第一电子设备执行步骤S202、在发现窗口结束后发送数据帧。
可选的，第一电子设备判断是否允许在发现窗口内发送数据帧，可以实现为：第一电子设备判断是否满足允许第一电子设备在发现窗口内发送数据帧的第一条件，若满足第一条件，则允许在发现窗口内发送数据帧，若不满足第一条件，则不允许在发现窗口内发送数据帧。或者，第一电子设备判断是否允许在发现窗口内发送数据帧，可以实现为：由其他电子设备(比如集群内的第二电子设备)判断是否允许第一电子设备在发现窗口内发送数据帧，若允许，则该第二电子设备通知第一电子设备允许在发现窗口内发送数据帧(第一指示信息)，若不允许，则该第二电子设备通知第一电子设备不允许在发现窗口内发送数据帧。
可选的，第二电子设备判断是否允许第一电子设备在发现窗口内发送数据帧，可以实现为：第二电子设备判断是否满足第一条件，若满足第一条件，则该第二电子设备通知第一电子设备允许在发现窗口内发送数据帧，若不满足第一条件，则该第二电子设备通知第一电子设备不允许在发现窗口内发送数据帧。
可选的，第一条件包括如下任一项或多项条件的组合：发现窗口的信道繁忙度小于第一阈值，集群所在网络的丢包率小于第二阈值，集群所在网络的重传率小于第三阈值，集群内的设备数目小于第五阈值，接收信号强度指示(received signal strength indication，RSSI)高于第六阈值，待发送数据帧的业务优先级高于第四阈值。
可选的，上述各阈值可以是预先设置的，比如出厂设置好的，也可以是后续通信 过程中设置的。本申请实施例不限制阈值的设置方式以及阈值的具体数值。
通常，集群内的设备数目较少时，设备之间在发现窗口内交互的管理帧也较少，这些管理帧可能仅占用发现窗口的一小部分时域资源，此种情况下，发现窗口中很可能存在大量闲置时域资源。本申请实施例中，若第一电子设备确定有待发送的数据帧，且集群内的设备数目小于第五阈值，则可以通过发现窗口的空闲时域资源发送数据帧。比如，基于Wi-Fi的载波侦听机制，在侦听到信道空闲时，在发现窗口内发送数据帧。如此一来，可以提升发现窗口内时域资源的利用率，避免空口资源浪费，并且，通过在发现窗口内及时发送数据帧，能够降低数据帧的时延，进而降低业务时延。
反之，若第一电子设备确定有待发送的数据帧，且集群内的设备数目大于或等于第五阈值(说明空口竞争强)，则不允许在发现窗口内发送数据帧，也就是，需要在当前发现窗口结束后发送该待发送数据帧。如此一来，可避免空口竞争导致的管理帧丢失。
在一些场景中，网络的丢包率较小，说明网络状况较好，在发现窗口内，设备之间的竞争程度较小。此种情况下，发现窗口中很可能存在较多闲置的时域资源。考虑到该情况，本申请实施例中，若第一电子设备确定网络的丢包率小于第二阈值，则允许在发现窗口内发送数据帧，以便高效利用闲置的时域资源。反之，若第一电子设备确定网络的丢包率大于或等于第二阈值，则不允许在发现窗口内发送数据帧，以避免过多设备竞争发现窗口的资源。
在一些场景中，待发送数据帧的业务优先级较高的情况下，往往需要优先发送该待发送数据帧，以满足业务指标需求。可选的，优先级高的业务，可以包括但不限于是低时延业务。示例性的，低时延业务包括但不限于如下任一项或多项：游戏、网课、即时通信、直播、抢红包、投屏、物联网业务、工业物联网业务。
本申请实施例中，若第一电子设备确定有待发送数据帧，且待发送数据帧的业务优先级高于(大于)第四阈值，则允许第一电子设备在发现窗口内发送该待发送数据帧，以尽可能满足业务需求。反之，若第一电子设备确定有待发送数据帧，且待发送数据帧的业务优先级小于或等于第四阈值，则不允许第一电子设备在发现窗口内发送该待发送数据帧。
在一些场景中，设备的接收信号强度指示(received signal strength indication，RSSI)表征信号强度较强，说明网络状况较好，这种情况下，在发现窗口内，设备之间的竞争程度往往较小，发现窗口中很可能存在较多闲置的时域资源。考虑到该情况，本申请实施例中，若第一电子设备确定存在待发送数据帧，且检测到RSSI高于第六阈值，则允许在发现窗口内发送该待发送数据帧。反之，若第一电子设备确定存在待发送数据帧，且检测到RSSI小于或等于第六阈值，则不允许在发现窗口内发送该待发送数据帧。
可选的，第一电子设备或集群内其他设备可按周期或其他策略统计上述第一条件中各参数的值，第一电子设备可根据统计值确定是否允许在发现窗口内发送数据帧。
以统计丢包率为例，第一电子设备可检测发现窗口的前一段时间内网络的丢包率，比如发现窗口的前半个窗口内网络的丢包率，若前半个发现窗口内的丢包率小于阈值，则可推测后半个发现窗口内的丢包率也较小，那么，第一电子设备允许在后半个发现 窗口内发送数据帧。反之，若前半个发现窗口内的丢包率大于或等于阈值，则不允许在后半个发现窗口内发送数据帧。
或者，第一电子设备通过判断前N(N为正整数)个调度周期的发现窗口内的丢包率，来确定在当前调度周期的发现窗口内是否发送数据帧。比如，前一个调度周期的发现窗口内的丢包率小于阈值，则可推测后当前发现窗口内的丢包率也较小，那么，第一电子设备允许在当前发现窗口内发送数据帧。反之，若上个发现窗口内的丢包率大于或等于阈值，则不允许在当前发现窗口内发送数据帧。
或者，第一电子设备基于其他方式确定发现窗口网络的丢包率。本申请实施例不限制确定发现窗口内丢包率的具体实现方式。
示例性的，手机确定在发现窗口内存在待发送数据帧(需要在发现窗口内发送的数据帧)，并且，手机所在集群网络当前的丢包率较小，那么，手机可以在发现窗口内发送数据帧。
再示例性的，手机确定在发现窗口内存在待发送数据帧(需要在发现窗口内发送的数据帧)，并且，手机所在集群网络当前的重传率较小，那么，手机可以在发现窗口内发送数据帧。
再示例性的，手机确定在发现窗口内存在待发送数据帧，并且，该数据帧的业务优先级较高(比如为抢红包业务)，那么，手机可以在发现窗口内发送数据帧。
再示例性的，手机确定在发现窗口内存在待发送数据帧，并且，手机所在集群网络当前的RSSI较大，那么，手机可以在发现窗口内发送数据帧。
再示例性的，手机确定在发现窗口内存在待发送数据帧，并且，该数据帧的业务优先级较高(比如为抢红包业务)，集群内当前的设备数目较少，那么，手机可以在发现窗口内发送数据帧。
再示例性的，若畅连通话应用开启了本申请实施的WLAN传输增强功能，那么，后续在集群内的设备数较少时，畅连通话的数据可在发现窗口内发送。
再示例性的，若畅连通话应用开启了本申请实施的WLAN传输增强功能，且假设语音通话为高优先级业务，那么，后续用户在通过畅连通话应用进行语音通话时，电子设备可以在发现窗口内发送语音数据。
可以理解，除了上述列举的几种条件之外，第一条件还可以是其他任何可以表明发现窗口有闲置时域资源的条件。本申请实施例并不限制第一条件的具体内容。
示例性的，如图13所示，在发现窗口1期间，数据帧队列中存在待发送的数据帧1、2、3，此时，若满足第一条件(比如集群内的设备数目较少)，则第一电子设备可以在发现窗口1内及时调度发送数据帧，比如调度发送数据帧1。在发现窗口2期间，数据帧队列中存在待发送的数据帧3、4、5，此时，若不满足第一条件(比如集群内的设备数目较多)，则第一电子设备不可以在发现窗口2内调度发送数据帧，需等待发现窗口2结束后才能调度发送数据帧。
与实施例一中默认允许在发现窗口内发送数据帧相比，实施例二的技术方案中，可以根据第一条件动态调整是否允许在发现窗口发送数据帧，使得能够在适合的条件下允许在发现窗口内发送数据帧。
可选的，上述第一条件(用于判断是否允许在发现窗口内发送数据帧的条件)可 以由第一电子设备自行判断，也可以由集群内的其他设备判断第一条件，并将第一条件的判断结果，比如指示是否允许第一电子设备在发现窗口内发送数据帧的指示消息发给第一电子设备，如此，第一电子设备能够确定是否允许在发现窗口内发送数据帧。如下分别这两种判断第一条件的方式。
可选的，第一电子设备，或集群内的其他设备可以按周期或其他策略判断第一条件。示例性的，可以每个调度周期判断一次是否满足第一条件。如图13所示，两个调度周期内，第一个调度周期内，满足第一条件，那么，第一电子设备可以在发现窗口内发送数据帧。第二个调度周期内，不满足第一条件，那么，第一电子设备需等待发现窗口结束才能发送数据帧。当检测周期较短时，可以及时调整不同发现窗口内的调度策略，能够进一步降低业务时延，及时调整资源利用率。
再示例性的，可以每L(L为正整数)个调度周期判断一次是否满足第一条件。本申请实施例并不限制判断第一条件的具体周期以及方式。当检测周期较长时，可以降低检测第一条件的复杂度。

实施例五
本申请实施例还提供一种数据传输方法，可以允许集群内的部分设备在发现窗口内发送数据帧。如图23所示，该方法包括：
S701、第二电子设备确定允许在发现窗口内发送数据帧的设备。
可选的，第二电子设备是主设备。在另一些实施例中，第二电子设备也可以是从设备。本申请实施例不限制第二电子设备的角色。

示例性的，第一电子设备接收到图24所示的信标帧后，解析该信标帧，读取Mac地址字段，若Mac地址字段所指示的Mac地址不包括自身的Mac地址，说明自身不被允许在发现窗口发送数据帧，第一电子设备需要执行S202。
S202、第一电子设备在发现窗口结束后发送数据帧。
在另一些实施中，第一电子设备在发现窗口内发送的数据帧满足如下任一项或多项条件：数据量小于第七阈值、发送速率小于第八阈值、发送次数小于第九阈值。如此一来，能避免第一电子设备在发现窗口发送过多数据导致的发现窗口拥塞的问题，维持网络性能的稳定性。
可选的，第七阈值、第八阈值、第九阈值可以是预先设置的，比如设备出厂是预设的，也可以是设备之间动态交互的。可选的，第七阈值、第八阈值、第九阈值可以根据当前网络的状况确定，比如，集群内的设备数目较多时，第七阈值相应较小，集群内的设备数目较多时，第七阈值相应较大。该方式中，可以通过调整各阈值的值， 动态调整设备在发现窗口发送的数据量、发送速率、发送次数，使得数据量、发送速率、发送次数与当前的网络状况相匹配，获得更高的数据传输性能。
