图1示出了一种无线数据传输方法的应用场景示意图。
参考图1，在本场景中，包括服务端(Server)11、根无线接入点(Root AP)12、中继无线接入点1(Repeater AP1)13、中继无线接入点2(Repeater AP2)14、中继无线接入点3(Repeater AP3)15，无线工作站(Wi-Fi Station，STA1)16。根无线接入点12与服务端11连接，服务端11可以是提供业务的服务器、主机或者核心网等。根无线接入点(Root AP)12、中继无线接入点1(Repeater AP1)13、中继无线接入点2(Repeater AP2)14、中继无线接入点3(Repeater AP3)15则可以是无线网络设备，如无线路由器、无线交换机、无线信号放大器等。本申请实施例对无线网络设备的具体类型不作任何限制。无线工作站16可以是能够通过无线网络联网的用户设备，如智能手机、笔记本电脑、平板电脑等，也可以是支持无线联网终端设备等，在此不做限制。
图2示出了一种现有技术中多级Wi-Fi组网的架构。
在图1示出的场景中，STA1与AP0进行数据交互时，可以参考图2示出的架构。参考图，根无线接入点下包括一个无线接入模块(AP0)，中继无线接入点1下包括一个无线接入模块(AP1)和一个虚拟无线工作站(VSTA1)、中继无线接入点2下包括一个无线接入模块(AP2)和一个虚拟无线工作站(VSTA2)、中继无线接入点3下包括一个无线接入模块(AP3)和一个虚拟无线工作站(VSTA3)。AP0与VSTA1连接、AP1与VSTA2连接、AP2与VSTA3连接，AP3与STA1连接。
当AP0与STA1进行数据交互时，下行方向需经过：
AP0→中继无线接入点1(VSTA1→AP1)→中继无线接入点2(VSTA2→AP2)→中继无线接入点3(VSTA3→AP3)→STA1。这个过程中，至少需要经过四次空口交互。
相应的，上行方向需经过：
STA1→中继无线接入点3(AP3→VSTA3)→中继无线接入点2(AP2→VSTA2)→中继 无线接入点1(AP1→VSTA1)→AP0。这个过程中，也至少需要经过四次空口交互。
当所有设备均处于一个冲突域中时，每个设备获取空口的几率相同，则Server与STA1的一次交互平均需要经历64次空口交互。STA所在级联层级越深、冲突域内设备数目越多，需要经历的空口交互的次数越多，空口交互的时延开销越大，低时延业务的质量越难保障。
为此，本申请提供了一种无线数据传输方法，可以应用于多个依次级联的无线接入点设备中的一个。无线接入点设备包括无线接入模块、第一虚拟传输模块和第二虚拟传输模块。无线接入点设备的无线接入模块同时向上一级无线接入点设备的第二虚拟传输模块发送上行数据，以及向下一级无线接入点的第一虚拟传输模块发送下行数据。
通过无线接入点设备中的第一虚拟传输模块接收来自上一级无线接入点设备的下行数据，通过第二虚拟传输模块接收来自下一级无线接入点设备的上行数据，并通过无线接入模块将接收到上行数据和下行数据转发。由于无线接入模块同时发送上行数据和下行数据，可以合并上行和下行的空口，有效减少空口交互的次数，进而降低空口交互时延开销，保证低时延业务的质量。

图4是本申请实施例的无线网络设备的软件结构示意图。无线网络设备中的操作系统可以是林纳斯(Linux)系统、安卓(Android)系统或者鸿蒙系统(Harmony OS)等。在此，以无线网络设备的操作系统为鸿蒙系统为例进行说明。
在一些实施例中，可将鸿蒙系统分为四层，包括内核层、系统服务层、框架层以及应用层，层与层之间通过软件接口通信。
如图4所示，内核层包括内核抽象层(Kernel Abstract Layer，KAL)和驱动子系统。KAL下包括多个内核，如Linux系统的内核Linux Kernel、轻量级物联网系统内核LiteOS等。驱动子系统则可以包括硬件驱动框架(Hardware Driver Foundation，HDF)。硬件驱动框架能够提供统一外设访问能力和驱动开发、管理框架。多内核的内核层可以根据系统的需求选择相应的内核进行处理。

S302、无线接入点设备的第二虚拟传输模块接收来自下一级无线接入点设备的无线接入模块发送的上行数据。
S303、无线接入点设备的无线接入模块同时向上一级无线接入点设备的第二虚拟传输模块发送上行数据，以及向下一级无线接入点的第一虚拟传输模块发送下行数据。
一些实施方式中，第一虚拟传输模块为虚拟前传STA(Virtual fronthaul STA，VFSTA)，用于接收上一级无线接入点设备发送的下行数据。第二虚拟传输模块为虚拟回传STA(Virtual backhaul STA，VBSTA)，用于接收下一级无线接入点设备发送的上行数据。无线接入(Access Point，AP)模块用于与其他无线接入点设备以及STA进行无线连接。当AP模块与VFSTA和VBSTA连接时，可以向VFSTA和VBSTA发送下行数据、以及向VBSTA发送上行数据。
在本实施例中，参考图6，多个无线接入点设备依次级联，当无线接入点设备的级联层级为最低级时，无线接入点设备为Root AP。Root AP与服务端设备连接。Root AP的VBSTA接收来自下一级无线接入点设备(Repeater AP1)的AP模块(AP1)发送的上行数据，并将上行数据转发给Root AP的AP模块(AP0)。
当无线接入点设备的级联层级为最高级时，无线接入点设备为Repeater AP3，且与客户端设备(STA1)连接。
Repeater AP3的AP模块(AP3)接收来自STA1的上行数据。AP3向上一级无线接入点设备(Repeater AP2)的第二虚拟传输模块(VBSTA2)发送来自STA1的上行数据。
Repeater AP3的VFSTA接收来自AP2发送的下行数据。AP3将下行数据发送至客户端设备。
图7示出了一种无线接入点设备中各个模块数据转发的示意图。
需要说明的是，VFSTA和VBSTA在将接收到的上行数据和下行数据转发给AP时，可以参考图7示出的数据流向。其中，VBSTA和VFSTA不会主动占用空口发送数据，而是将接收到的数据通过桥接(Bridge)转发至AP。然后，通过AP同时将上行数据和下行数据进行发送。发送时，可以通过正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)将上行数据和下行数据集成在一个信号中，同时向上一级的VFSTA以及下一级的VBSTA发送。
一些实施方式中，可以参照表1示出的桥接转发表对桥接进行配置。
表1
目的地址 源端口 目的端口
- VFSTA AP
- VBSTA AP
其中，上行数据的目的地址可以为服务端的ip地址，下行数据的目的地址可以为客户端的ip地址，具体的目的地址以应用时的配置为准。
当桥接根据表1配置后，若桥接接收到的报文的源端口为VFSTA或VBSTA时，则直接将报文转发至AP。

- VBSTA1’ AP1
当桥接根据表2配置后，若桥接接收到的报文的源端口为VFSTA1、VBSTA1以及VBSTA1’时，则直接将报文转发至AP1。
在本实施例中，由于使用AP同时发送上行数据和下行数据，当所有设备在同一冲突域中时，Server与STA1进行一次交互平均需要经历25次空口交互。与现有技术相比，空口交互的次数明显降低，能够有效减少空口交互的时延开销，保证了低时延业务的质量。
本申请还提供了一种无线数据传输系统，参考图6示出的架构。无线数据传输系统包括服务端设备(Server)、第一无线接入点设备(Root AP)、一个或多个第二无线接入点设备(Repeater AP1和Repeater AP2)、第三无线接入点设备(Repeater AP3)以及客户端设备(Wi-Fi Station)。服务端设备与第一无线接入点设备连接。第一无线接入点设备、一个或多个第二无线接入点设备、以及第三无线接入点设备依次级联。第三无线接入点设备与客户端连接，第一无线接入点设备、第二无线接入点设备以及第三无线接入点设备均包括无线接入模块(AP)、第一虚拟传输模块(VFSTA)和第二虚拟传输模块(VBSTA)。
无线数据传输系统在运行时，服务端设备向第一无线接入点设备发送下行数据。第一无线接入点设备接收下行数据，并通过无线接入模块向第二无线接入点设备发送下行数据。第二无线接入点设备通过第一虚拟传输模块接收下行数据，并通过无线接入模块向第三无线接入点设备发送下行数据。第三无线接入点设备通过第一虚拟传输模块接收下行数据，并向客户端发送下行数据。
客户端设备向第三无线接入点设备的无线接入模块发送上行数据。第三无线接入点设备通过无线接入模块接收上行数据，并通过无线接入模块向第二无线接入点设备的第二虚拟模块发送上行数据。第二无线接入点设备通过接收上行数据，并通过无线接入模块向第一无线接入点设备的第二虚拟传输模块发送上行数据。第一无线接入点设备通过第二虚拟传输模块接收上行数据，并向服务端发送上行数据。
运行时的具体实现方式可以参考上述无线数据传输方法中的示例，在此不做赘述。
一些实施方式中，参考图6，当第二无线接入点设备为多个时(Repeater AP1和Repeater AP2)，级联层级最低的第二无线接入点设备(Repeater AP1)与第一无线接入点(Root AP)设备连接。级联层级最高的第二无线接入点设备(Repeater AP2)与第三无线接入点设备(Repeater AP3)连接。
Repeater AP1和Repeater AP2之间进行数据传输时，VBSTA1接收AP2发送的上行数据，AP1向VFSTA2发送下行数据。
一些实施方式中，可以向无线数据传输系统中增加新的无线接入点设备。在新增无线接入点设备时，新增的无线接入点设备根据配置的第一接入信息确定新增的无线接入点设备的接入位置。新增的无线接入点设备的第一虚拟传输模块根据配置的第一接入信息与接入位置对应的无线接入点设备的无线接入模块连接，并将新增的无线接入点设备的第二接入信息发 送给接入位置对应的无线接入点设备。接入位置对应的无线接入点设备的第二虚拟传输模块根据第二接入信息与新增的无线接入点设备的无线接入模块连接。
图9示出了本申请提供的向无线数据传输系统中新增无线接入点设备时的流程示意图。
作为示例，参考图9，当通过预设的级联选路算法为新增的无线接入点设备(Repeater AP1)配置Root AP中AP0的接入信息(第一接入信息)，Repeater AP1确定接入位置为Root AP后。可以通过以下步骤将Repeater AP1接入Root AP。其中，Repeater AP1包括AP1和VFSTA1，Root AP包括AP0。
S401、Repeater AP1的VFSTA1在AP0认证上线。
在本实施例中，AP0的接入信息包括AP0的服务集标识(Service Set Identifier，SSID)，VFSTA1可以根据AP0的SSID与AP0认证连接，当VFSTA1与AP0完成认证并连接成功后，VFSTA1即在AP0上认证上线。
S402、Repeater AP1将AP1的接入信息发送给AP0。
在本实施例中，可以通过VFSTA1将AP1的接入信息(第二接入信息)发送给AP0。例如，VFSTA1可以通过VBSTA_Notify_Action帧记录AP1的接入信息。AP1的接入信息可以包括AP1的SSID或基本服务集标识(Basic Service Set Identifier，BSSID)。
表3
类别 组织标识 特定供应商上下文
1 j variable
表3示出了供应商框架(Vendor Specific Frame)的结构，其中，类别(category)和组织标识(organization identifier)可根据Repeater AP1的实际情况确定，例如，参考表3，类别可以为1，组织标识可以为j。特定供应商上下文(Vendor Specific Content)的内容为变量(variable)，因此，VFSTA1可以将VBSTA_Notify_Action帧通过Vendor Specific Frame中的Vendor Specific Content进行记录。
S403、Root AP创建VBSTA0，设置VBSTA0与AP0的转发路径。
一些实施方式中，VBSTA0与AP0的转发路径的设置方式可以参照表1示出的桥接转发表进行设置，在此不做赘述。
S404、AP0将AP1的接入信息发送给VBSTA0。
一些实施方式中，AP0可以通过Root AP的内部消息发送给VBSTA0，内部消息可以通过Root AP内部的总线进行传递，在此不对内部消息的类型进行限制。
S405、VFSTA0在AP1认证上线。
一些实施方式中，S405的实现方式与S401类似，在此不做赘述。
一些实施方式中，当无线接入点设备接入多个新增的无线接入点设备时，为每个新增的无线接入点设备创建一个对应的第一虚拟传输模块。为每个新增的无线接入点设备创建对应的第一虚拟模块的步骤可参考S401-S405，在此不做赘述。应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
