Description

WiFi网络中的数据传输方法、装置及设备
本申请要求于2018年10月22日提交中国国家知识产权局、申请号为201811232110.5、申请名称为“一种WiFi网络中数据传输的方法”的中国专利申请的优先权，以及于2019年6月24日提交中国国家知识产权局、申请号为201910547973.X、申请名称为“WiFi网络中的数据传输方法、装置及设备”的中国专利申请的优先权，它们的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，尤其涉及一种无线保真(wireless fidelity，WiFi)网络中数据传输方法、装置及设备。
背景技术
在现有的无线保真(wireless fidelity，WiFi)系统中，同一接入点(access point，AP，又称为家庭路由器或家庭网关)下的不同终端，如站点(station，STA)，通常采用竞争方式抢占网络资源，以完成各种业务，如语音、视频、网页浏览、下载、游戏等的数据传输。因此，当通信环境较差，如干扰较强、信号较弱、资源不足、负载较大时，一部分终端的数据传输可能对另一部分终端的数据传输产生不良影响。例如，终端A的视频播放业务占用带宽较大，可能会挤占终端B的游戏业务的可用带宽，从而导致终端B的游戏业务的下行传输时延增大，进而造成游戏卡顿。
为此，现有无线服务质量(quality of service，QoS)协议，如WiFi多媒体(WiFi multimedia，WMM)协议，按照优先级从高到低顺序依次定义了4种接入类型(access category，AC)的优先级队列：语音(voice，VO)流、视频(video，VI)流、尽力而为(best-effort，BE)流、背景(back-ground，BK)流。AP可以据此优先转发具有高优先级接入类型的业务的数据，以针对不同业务类型，分别提供差异化数据传输服务。
然而，在实际的数据传输过程中，尤其在下行数据传输过程中，上述优先级往往不能有效执行，如忽略(如不支持或不解析或不执行)已设置的优先级、篡改(如随意降低、抬高)已设置的优先级、滥用优先级设置权限(如所有类型业务均设置为最高优先级)等，从而导致现有WiFi网络提供差异化数据传输服务的可靠性较差。
发明内容

上述网络接入设备为位于上述通信系统网络侧，且具有无线收发功能的设备或可设置于该设备的芯片。该网络接入设备包括但不限于：WiFi系统中的接入点(access point，AP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，新空口(new radio，NR)系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
上述终端为接入上述通信系统，且具有无线收发功能的终端设备或可设置于该终 端设备的芯片。该终端设备也可以称为用户设备(user equipment，UE)、用户装置、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)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、智慧家庭(smart home)中的无线终端等。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
下面结合附图，详细描述本申请实施例提供的WiFi网络中的数据传输方法、装置及设备。
图2示出了本申请实施例提供的一种WiFi网络中的数据传输方法的流程示意图，以适用于图1所示的通信系统中终端与网络接入设备之间的通信。如图2所示，该WiFi网络中的数据传输方法包括如下步骤：
S201，网络接入设备接收上行报文。
示例性地，网络接入设备可以通过与终端之间的无线连接，如WiFi系统中的无线连接或蜂窝网中的上行(uplink)链路接收终端发送的上行报文。其中，上行报文可以携带上行五元组信息。示例性地，该上行五元组信息可以包括：上行源互联网协议(internet protocol，IP)地址、上行目的IP地址、上行源端口、上行目的端口和上行传输协议类型。其中，上行源IP地址和上行源端口可以是终端的IP地址和端口号，上行目的IP地址和上行目的端口可以是服务器的IP地址和端口号，上行传输协议类型可以是上行报文采用的传输协议类型，如用户数据报协议(user data gram protocol，UDP)、传输控制协议(transmission control protocol，TCP)等。
可选地，上行报文还可以携带用户设置的实时传输指示。该实时传输指示用于指示网络接入设备优先转发该用户设置的一种或多种业务类型的下行报文。
表1示出了现有WMM协议规定的一种转发优先级的映射关系示例。如表1所示，第2列至第4列依次为：差异化服务代码点(differentiated services codepoint，DSCP)、802.11e中定义的用户优先级(user priority，UP)、接入类型AC。例如，参考接入类型AC，视频流和音频流为需要优先转发的业务类型，其中，音频流的转发优先级要高于视频流。相对应的，视频流和音频流分别对应用户优先级取值为4-5和6-7，且分别对应DSCP取值为32-47和48-63。容易理解，网络接入设备可以解析报文中携带的DSCP值、UP值和AC值中的一种或多种，为不同用户或业务类型提供差异化的数据传输服务。
示例性地，在现有的WMM协议中，游戏业务被视为视频流，其转发优先级低于音频流。因此，对于游戏用户而言，当语音流的下行报文的数量较多，或者除游戏之外的其他视频流，如视频播放的下行带宽占用率较高时，鉴于游戏业务的转发优先级低于语音流，且与其他视频流相同，网络接入设备可能不会优先转发游戏报文，导致 游戏报文的传输时延较大，从而导致游戏卡顿等问题，体验较差。
在本申请实施例中，可以手动设置预设业务类型，如上述用户最为感兴趣的游戏业务的实时传输指示，也就是为预设业务类型设置较高的转发优先级。示例性地，用户可以在预设业务类型的上行报文中设置上述实时传输指示。具体地，可以在上述上行报文中头部的DSCP字段或者ToS字段中设置如下一项或多项实时传输指示：与最高转发优先级对应的差异化服务代码点DSCP值、与最高转发优先级对应的用户优先级UP值、与最高转发优先级对应的接入类型AC或最低传输延时等。
例如，上述游戏用户可以通过终端的游戏界面，为该游戏的下行报文的转发优先级设置为最高优先级，如高于或等于语音流的转发优先级。具体地，游戏用户可以通过终端提供的输入接口，如该游戏软件的图形用户界面或命令行输入窗口，输入的实时传输指示。其中，实时传输指示可以为一个数值较小的最大转发时延，如10毫秒(millisecond，ms)、20ms等，也可以为最高转发优先级所对应的优先级取值，本申请实施例对此不作限定。

Figure PCTCN2019112391-appb-000001
此外，上行报文还可以携带上行报文的包长、发送时间等信息。
S202，网络接入设备记录上行报文携带的实时传输指示和上行五元组信息。
示例性地，网络接入设备可以将上述实时传输指示和上行五元组信息记录在接入网本地的存储空间中，如记录在网络接入设备的报文转发表中，或者可由接入网的控制程序调用的配置文件中，本申请实施例对此不作限定。
此外，网络接入设备还可以获取来自指定终端的上行报文的统计信息。示例性地，网络接入设备可以解析上行报文携带的发送时间，并结合该网络接入设备接收该上行报文的接收时间，计算该上行报文从终端到网络接入设备的传输延时。容易理解，网络接入设备还可以统计指定时间段内来自指定终端的上行报文的包长和数量，计算该 指定终端占用的传输带宽。
S203，网络接入设备接收下行报文。其中，下行报文携带有下行五元组信息。
示例性地，网络接入设备可以通过与外部网络，如外部网络中的服务器之间的通信连接，如包括光纤、网线等通信线缆，和/或中间节点的网络路由，接收外部网络发送的下行报文。其中，上述下行五元组信息可以包括：下行源互联网协议IP地址、下行目的IP地址、下行源端口、下行目的端口和下行传输协议类型。其中，下行源IP地址和下行源端口可以是外部网络中的某台设备，如服务器的IP地址和端口号，下行目的IP地址和下行目的端口可以是终端的IP地址和端口号，下行传输协议类型可以是下行报文采用的网络传输协议类型，如UDP协议、TCP协议等。
需要说明的是，上行报文和下行报文可以采用相同的传输协议类型，也可以采用不同的传输协议类型，本申请实施例对此不做限定。
此外，网络接入设备还可以获取来自外部网络，如指定服务器的下行报文的统计信息。示例性地，网络接入设备可以解析下行报文携带的发送时间，并结合该网络接入设备接收该信息报文的接收时间，计算该信息报文从外部网络到网络接入设备的传输延时。容易理解，网络接入设备还可以统计指定时间段内来自指定服务器的下行报文的包长和数量，计算该下行报文占用的传输带宽。
S204，网络接入设备确定下行报文的业务类型为预设业务类型，且下行五元组信息与上行五元组信息匹配。
本申请实施例中，预设业务类型可以由用户手动设置。例如，游戏用户通过终端中安装的网络游戏的用户图形界面中的设置按钮，将该网络游戏设置为预设业务类型。再例如，网络小说用户可以通过终端中安装的网络小说应用程序的用户图形界面中的设置按钮，将该网络小说设置为预设业务类型。
具体地，可以根据如下至少一项参数，设置预设业务类型：如提供该预设业务类型的服务的网络设备的IP地址、端口号、采用的传输协议类型、占用的上/下行带宽、包长、到达时间偏差等。相应地，网络接入设备可以接收终端设置的预设业务类型的上述参数，并依据上述参数和网络接入设备的统计信息，下行报文占用带宽、传输时延、QoS信息等，确定接收的下行报文的业务类型是否为预设业务类型。
示例性地，以游戏为例，上述确定下行报文的业务类型为预设业务类型，可以包括如下步骤：
若下行报文满足如下至少一项条件，则确定下行报文的业务类型为预设业务类型：
下行源IP地址为提供实时传输业务的源IP地址，如游戏服务器的IP地址；
下行源端口为提供实时传输业务的源端口，如游戏服务器的发送端口号；
下行传输协议类型为实时传输业务采用的传输协议类型，如该游戏报文采用的传输协议类型，可以为UDP协议或TCP协议；
下行报文占用的带宽小于下行带宽阈值，其中，下行带宽阈值为一个较小值，如小于0.5兆比特每秒(mega bits per second，Mbps)、1Mbps等；
下行报文的包长小于下行包长阈值，如100字节(bytes，B)等；
任意两个相邻的下行报文的到达时间之间的偏差小于下行时间偏差阈值，如50ms，或100ms等，也就是下行报文的到达时间间隔比较平稳。
容易理解，对于不同预设业务类型的下行报文，如视频播放，上述判断条件可能不同。例如，上述下行报文占用的带宽小于下行带宽阈值可能替换为：下行报文占用的带宽大于或等于另一个下行带宽阈值，其中，该另一个下行带宽阈值通常为一个较大值，如1Mbps。再例如，下行报文的包长大于或等于下行包长阈值，其中，下行包长阈值可以为200字节、500字节等。
鉴于下行报文的传输方向与上行报文的传输方向相反，对于同一终端与外部网络中的同一网络设备，如游戏服务器之间预设业务类型，其下行报文的源IP地址、源端口、目的IP地址、目的端口是分别与S202中记录的上行报文的目的IP地址、目的端口、源IP地址、源端口相对应的。因此，可选地，上述下行五元组信息与上行五元组信息匹配，可以包括：
下行源IP地址与上行目的IP地址相同；
下行目的IP地址与上行源IP地址相同；
下行源端口与上行目的端口相同；
下行目的端口与上行源端口相同；
下行传输协议类型与上行传输协议类型相同。
S205，网络接入设备按照实时传输指示，优先转发下行报文。
示例性地，若在S204中确定下行报文为预设业务类型的报文，且在S204中确定下行五元组信息与S202中记录的上行五元组信息匹配，则可确定该下行报文为需要优先转发的预设业务类型的下行报文，并根据S202中记录的实时传输指示，优先向终端转发该下行报文。
可选地，网络接入设备可以根据S202中记录的上行报文携带的实时传输指示，将该上行报文携带的上行五元组下行，或者与该上行五元组信息匹配的下行五元组信息添加到网络接入设备本地的路由转发表中。当网络接入设备确定接收到下行报文为预设业务类型，和/或，接收到下行报文携带的下行五元组信息与上述路由转发表中的上行五元组信息或下行五元组信息匹配时，立即转发该下行报文。
可选地，网络接入设备也可以不修改路由转发表，而是将上述优先转发相关操作嵌入式地写入该接入设备的控制程序中，或者写入可由该网络接入设备的控制程序能够调用的配置文件中，本申请实施例对此不做限定。
容易理解，当网络接入设备需要转发的下行报文的数据量较小时，或者下行报文占用的带宽较小时，并不会对预设业务类型的下行报文的转发造成不良影响，如传输延时仍然可以在可接受范围内，不会影响用户体验。因此，为了降低网络接入设备的控制复杂度，在一种可能的设计方法中，在执行上述S204网络接入设备确定下行报文的业务类型为预设业务类型之前，图2所示的WiFi网络中的数据传输方法，还可以包括如下一项或多项：
确定下行数据量大于下行数据量阈值；
确定下行带宽大于下行带宽阈值。
此外，为了进一步降低接入设备的控制复杂度，也可以为图2所示的WiFi网络中的数据传输方法设置退出机制。因此，在一种可能的设计方法中，图2所示WiFi网络中的数据传输方法，还可以包括如下步骤：
不再优先转发指定时间段内未出现的上行五元组信息和/或下行五元组信息对应的下行报文。其中，所述指定时间段可以由终端设置，也可以由网络接入设备默认设置，如可以设置为30分钟、1小时等。
容易理解，当网络接入设备的现有资源不能保证所有下行报文的转发需求时，还可以通过限制一部分下行报文的转发，以保证另一部分下行报文的转发需求。因此，在另一种可能的设计方法中，图2所示的WiFi网络中的数据传输方法，还可以包括如下步骤：
限制第一指定站点STA的下行报文带宽。
示例性地，上述限制第一指定站点STA的下行报文带宽，可以包括如下至少一项：
限制为第一指定站点STA优先转发的下行报文对应的上行五元组信息和/或下行五元组信息的数量；
限制为第一指定站点STA优先转发的下行报文的数量；
限制为第一指定站点STA优先转发的下行报文占用的连续传输时间；
在为第二指定站点STA优先转发下行报文的同时，限制第一指定站点STA的下行报文带宽。
本申请提供的WiFi网络中的数据传输方法，网络接入设备记录上行报文携带的实时传输指示和上行五元组信息，当下行报文的业务类型为预设业务类型时，网络接入设备可以按照上行报文的实时传输指示，优先转发下行五元组信息与上行五元组信息匹配的下行报文，能够在外部网络设备，如服务器，为预设业务类型的下行报文设置的高转发优先级被忽略或被篡改或被滥用的情况下，仍然能够根据上行报文的实时传输指示，优先转发与上行五元组匹配的下行报文，从而实现了优先转发预设业务类型的下行报文的目的，能够提高网络接入设备提供差异化数据传输服务的可靠性。
图3示出了本申请实施例提供的另一种WiFi网络中的数据传输方法的流程示意图，以适用于图1所示的通信系统中终端与网络接入设备之间的通信。如图3所示，该WiFi网络中的数据传输方法包括如下步骤：
S301，网络接入设备接收上行报文。其中，上行报文携带有实时传输指示和上行五元组信息。
S302，网络接入设备记录上行报文携带的实时传输指示和上行五元组信息。
S303，网络接入设备接收下行报文。其中，下行报文携带有下行五元组信息。
S301-S303的具体实现方式可以分别参考S201-S203，此处不再赘述。
S304，网络接入设备确定上行报文的业务类型为预设业务类型，且下行五元组信息与上行五元组信息匹配。
其中，预设业务类型的设置方式可以参考S204，此处不再赘述。
示例性地，以游戏为例，上述确定上行报文的业务类型为预设业务类型，可以包括如下步骤：
若上行报文满足如下至少一项条件，则确定上行报文的业务类型为预设业务类型：
上行目的IP地址为提供实时传输业务的目的IP地址，如游戏服务器的IP地址；
上行目的端口为提供实时传输业务的目的端口，如游戏服务器的发送端口号；
上行传输协议类型为实时传输业务采用的传输协议类型，如该游戏报文采用的传输协议类型，可以为UDP协议或TCP协议；
上行报文占用的带宽小于上行带宽阈值，其中，上行带宽阈值为一个较小值，如小于0.5Mbps、1Mbps等；
上行报文的包长小于上行包长阈值，如100字节等。
容易理解，对于不同预设业务类型的上行报文，上述判断条件可能不同，具体可以根据该不同预设业务类型的上行报文的业务特征进行设置，此处不再赘述。
需要说明的是，S304可以理解为包括了两个步骤：步骤A“确定上行报文的业务类型为预设业务类型”和步骤B“确定下行五元组信息与上行五元组信息匹配”。其中，S304中的步骤A“确定上行报文的业务类型为预设业务类型”可以在S301之后、S305之前的任一个时间点发生，所述步骤A与其他步骤之间的执行先后顺序可以有多种。在一种可能的实现中，所述步骤A可以在S301接收到上行报文之后立即执行，也就是可以在执行S302之前执行，或者在执行S302的过程中执行；这样的话，在S302中“记录的上行报文携带的实时传输指示和上行五元组信息”，就可以是已确定为预设业务类型的上行报文携带的实时传输指示和上行五元组信息，在此情况下，S302中记录的上行报文携带的实时传输指示和上行五元组信息的数量通常较小，从而可以节省网络接入设备的存储空间。
判断下行五元组信息与上行五元组信息匹配的实现方式，具体可以参考S204中的相关描述，此处不再赘述。
S305，网络接入设备按照实时传输指示，优先转发下行报文。
S305的具体实现方式可以参考S205，此处不再赘述。
容易理解，当网络接入设备需要转发的下行报文的数据量较小时，或者下行报文占用的带宽较小时，并不会对预设业务类型的下行报文的转发造成不良影响，如传输延时仍然可以在可接受范围内，不会影响用户体验。因此，为了降低网络接入设备的控制复杂度，在一种可能的设计方法中，在执行上述按照实时传输指示，优先转发下行报文之前，图3所示的WiFi网络中的数据传输方法，还可以包括如下一项或多项：
确定下行数据量大于下行数据量阈值；
确定下行带宽大于下行带宽阈值。
此外，为了进一步降低接入设备的控制复杂度，也可以为图3所示的WiFi网络中的数据传输方法设置退出机制。因此，在一种可能的设计方法中，图3所示的WiFi网络中的数据传输方法，还可以包括如下步骤：
不再优先转发指定时间段内未出现的上行五元组信息和/或下行五元组信息对应的下行报文。其中，所述指定时间段可以由终端设置，也可以由网络接入设备默认设置，如可以设置为30分钟、1小时等。
容易理解，当网络接入设备的现有资源不能保证所有下行报文的转发需求时，还可以通过限制一部分下行报文的转发，以保证另一部分下行报文的转发需求。因此，在另一种可能的设计方法中，图3所示的WiFi网络中的数据传输方法，还可以包括：
限制第一指定站点STA的下行报文带宽。
可选地，上述限制第一指定站点STA的下行报文带宽，可以包括如下至少一项：
限制为第一指定站点STA优先转发的下行报文对应的上行五元组信息和/或下行五元组信息的数量；
限制为第一指定站点STA优先转发的下行报文的数量；
限制为第一指定站点STA优先转发的下行报文占用的连续传输时间；
在为第二指定站点STA优先转发下行报文的同时，限制第一指定站点STA的下行报文带宽。
本申请提供的WiFi网络中的数据传输方法，网络接入设备确定上行报文的业务类型为预设业务类型，并记录该上行报文携带的实时传输指示和上行五元组信息，然后网络接入设备可以按照该上行报文的实时传输指示，优先转发下行五元组信息与上行五元组信息匹配的下行报文，能够在外部网络设备，如服务器，为下行报文设置的高优先级被忽略或被篡改或被滥用的情况下，仍然能够根据上行报文的实时传输指示，优先转发与上行五元组匹配的下行报文，从而实现了优先转发预设业务类型的下行报文的目的，能够提高网络接入设备提供差异化数据传输服务的可靠性。
需要说明的是，图2所示的WiFi网络中的数据传输方法和图3所示的WiFi网络中的数据传输方法也可以结合使用。例如，可以在上行报文的业务类型和下行报文的业务类型均为预设业务类型，且上行五元组与下行五元组匹配的情况下，才会根据上行报文的实时传输指示，优先转发下行报文，以进一步提高识别和转发高优先级下行报文的准确性和效率。
上述图2和图3所示的WiFi网络中的数据传输方法均为采用如下方式实现优先转发预设业务类型的下行报文的，即根据上行报文携带的实时传输指示，优先转发携带的下行五元组信息与该上行报文携带的上行五元组信息匹配的下行报文。为了进一步简化网络接入设备的设计复杂度，也可以只根据下行报文的流量特征，优先转发预设业务类型的下行报文。下面结合图4详细说明。
图4示出了本申请实施例提供的又一种WiFi网络中的数据传输方法的流程示意图，以适用于图1所示的通信系统中终端与网络接入设备之间的通信。如图4所示，该WiFi网络中的数据传输方法包括如下步骤：
S401，网络接入设备接收下行报文。
具体实现方式可以参考S203，此处不再赘述。
S402，网络接入设备确定下行报文的业务类型为预设业务类型。
具体实现方式可以参考S204，此处不再赘述。
S403，网络接入设备优先转发该下行报文。
具体地，若在S402中确定下行报文为预设业务类型的报文，即可优先向终端转发该下行报文。示例性地，可以将上述预设业务类型的判断和优先转发相关操作嵌入式地写入该接入设备的控制程序中，或者写入可由该网络接入设备的控制程序能够调用的配置文件中，本申请实施例对此不做限定。
本申请提供的WiFi网络中的数据传输方法，网络接入设备可以识别并优先转发预设业务类型的下行报文，可以解决在外部网络设备，如服务器，为下行报文设置的高优先级被忽略或被篡改或被滥用的情况下，网络接入设备不能优先转发预设业务类型 的下行报文的问题，能够提高网络接入设备提供差异化数据传输服务的可靠性。
