Description

一种数据传输方法及终端 技术领域
本发明涉及通信领域的通用串行总线(USB，Universal Serial Bus)抗干扰技术，尤其涉及一种数据传输方法及终端。
背景技术
近年来，随着通信技术的发展，无线网络设备在家庭中的应用越来越广泛，而且人们也希望无线网络设备能够支持多种通信方式，以便于人们在生活中随意选用。
现有技术中，为了满足用户需求，无线网络设备通常会同时兼容USB 3.0和无线保真(Wi-Fi，Wireless-Fidelity)。所述Wi-Fi的工作频段有两种，一种是2.4GHz(千兆赫兹)，即2412MHz-2472MHz频段，另一种是5GHz，即5150-5250MHz，5250-5350MHz，5470-5725MHz以及5725-5825MHz频段，所述USB3.0超高速数据传输时的工作频段主要在2.4-2.5频段范围。
由于USB 3.0在进行超高速数据传输时会产生一种宽频噪音，如果当前终端Wi-Fi正工作在2.4GHz频段，可能会对Wi-Fi信号产生干扰，降低Wi-Fi信号接收的灵敏度，进而缩减Wi-Fi信号的通信范围。
发明内容
为解决现有存在的技术问题，本发明实施例提供一种数据传输方法及终端，能够避免终端USB模块对Wi-Fi信号产生干扰，提高Wi-Fi信号的灵敏度，进而提高Wi-Fi信号的通信质量。
为达到上述目的，本发明实施例的技术方案是这样实现的：
本发明实施例提供了一种数据传输方法，包括：
若终端接入的无线访问接入点(Wi-Fi AP，Wireless Access Point)的工作频段为第一频段，确定终端当前是否正在通过第一USB模式进行数据传输；所述第一USB模式为所述第一频段的干扰模式；
若终端当前正在通过第一USB模式进行数据传输，切换至第二USB模式进行数据传输。
上述方案中，在所述确定终端当前是否正在通过第一USB模式进行数据传输之前，所述方法还包括：

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明实施例提供一种数据传输方法，应用于手机，平板电脑，笔记本电脑，路由器等同时支持USB3.0和Wi-Fi的终端，如图1所示，所述数据传输方法包括：
步骤101、若终端接入的Wi-Fi AP的工作频段为第一频段，确定终端当前是否正在通过第一USB模式进行数据传输；所述第一USB模式为所述第一频段的干扰模式。
示例的，通常终端的Wi-Fi模块默认支持2.4GHz和/或5GHz频段，即终端可以接入支持2.4GHz和/或5GHz频段的Wi-Fi AP进行工作，且所述Wi-Fi模块作为Wi-Fi station(站点)可以工作在2.4G或5G频段。所述2.4GHz频段指的是Wi-Fi联盟规定的ch1-ch13，即2412MHz-2472MHz频段。所述5GHz频段指的是Wi-Fi联盟规定的5150-5250MHz，5250-5350MHz，5470-5725MHz以及5725-5825MHz。
所述第一频段可以为2.4GHz频段，当终端当前接入的Wi-Fi AP的工作频段为2.4GHz频段时，说明终端当前的Wi-Fi可能会被USB3.0模式干扰，但是如果此时终端并没有通过USB3.0模式进行数据传输，即便终端当前USB模块的设置为USB3.0模式，也不会对Wi-Fi信号造成干扰，此时对USB模块传输模式的切换是无意义的。因此在当前终端接入的Wi-Fi AP的工作频段为2.4G Hz时，可以确定终端USB模块是否正在通过USB3.0模式进行超高速数据传输。
步骤102、若终端当前正在通过第一USB模式进行数据传输，切换至第二USB模式进行数据传输。
示例的，终端的USB模块默认的通信模式为USB3.0模式，所述USB3.0具有传统USB技术的易用性和即插即用功能，其实际传输速率平均是3.2Gbps(即320MB/S)，且具有后向兼容标准，即同时兼容USB1.1模式和USB2.0模式。
可选的，所述第一USB模式为USB3.0模式，所述第二USB模式为USB2.0模式或USB1.1模式。若终端当前正在通过USB3.0模式进行数据传输，则2.4GHz的Wi-Fi信号肯定会受到 USB3.0模式的干扰，为了避免干扰，可以将USB的通讯模式从USB3.0模式切换至USB2.0模式，由于USB 2.0模式的数据传输速率较小，因此不会对2.4GHz的Wi-Fi产生干扰。
这样一来，可以根据终端当前Wi-Fi的工作频段和USB的工作状态切换USB的工作模式，避免终端USB模块对Wi-Fi信号产生干扰，提高了Wi-Fi信号的灵敏度，进而提高了Wi-Fi信号的通信质量。
进一步的，在所述确定终端当前是否正在通过第一USB模式进行数据传输之前，终端还可以根据预设Wi-Fi AP列表中每个Wi-Fi AP的工作频段，选择接入的Wi-Fi AP，所述预设Wi-Fi AP列表包括多个Wi-Fi AP。
可选的，终端可以根据预设Wi-Fi AP列表中每个Wi-Fi AP的工作频段和预设策略，选择接入的Wi-Fi AP，所述预设策略可以为终端优先接入5G频段的Wi-Fi AP。具体的，如果当前存在2.4G和5G频段多个可连接的Wi-Fi AP，终端优先连接5G频段的Wi-Fi AP，如果所有5G频段的Wi-Fi AP连接失败，则继续连接2.4G频段的Wi-Fi AP；如果终端仅支持2.4G频段，不支持5G频段，则连接外部2.4G频段Wi-Fi AP。终端还可以根据Wi-Fi AP优先级或信号强度选择接入的Wi-Fi AP，本发明在此不做赘述。
进一步的，在所述根据预设Wi-Fi AP列表中每个Wi-Fi AP的工作频段，选择接入的Wi-Fi AP之前，终端还可以获取所述预设Wi-Fi AP列表中每个Wi-Fi AP的工作信道，然后根据所述每个Wi-Fi AP的工作信道，获取每个Wi-Fi AP的工作频段。
示例的，终端可以通过判断当前Wi-Fi AP的工作信道属于哪个频段区间获取Wi-Fi AP的工作频段。具体地，如果Wi-Fi AP的工作信道属于2412MHz-2472MHz频段，则Wi-Fi AP的工作频段是2.4GHz；如果AP的工作信道属于5150-5250MHz、5250-5350MHz、5470-5725MHz或5725-5825MHz，则Wi-Fi AP的工作频段是5GHz；如果当前外部Wi-Fi AP的工作信道属于其他频段，则Wi-Fi AP的工作频段是非法的，不在本发明的处理范围。
可选的，在获取所述预设Wi-Fi AP列表中每个Wi-Fi AP的工作信道时，可以根据每个Wi-Fi AP发送的Beacon(信标)报文，获取所述预设Wi-Fi AP列表中每个Wi-Fi AP的工作信道。
示例的，终端可以通过监听预设Wi-Fi AP列表中每个Wi-Fi AP发送的Beacon报文，对Wi-Fi AP进行扫描并获取工作信道，所述Beacon报文中携带有Wi-Fi AP的SSID以及Wi-Fi AP的工作信道信息，终端可以根据所述Beacon报文获取所述Wi-Fi AP的工作信道。如果所述Wi-Fi AP列表为空，终端可以监听外部所有Wi-Fi AP发送的报文，并获取能够接收到报文的每个Wi-Fi AP的工作信道。
可选的，在获取所述预设Wi-Fi AP列表中每个Wi-Fi AP的工作信道时，还可以接收每个Wi-Fi AP根据探测请求Probe request报文发送的探测响应Probe response报文，然后根据每个Wi-Fi AP的所述Probe response报文，获取预设Wi-Fi AP列表中每个Wi-Fi AP的工作信道。
示例的，终端也可以通过802.11协议的Probe request(探测请求)报文主动扫描所述Wi-Fi AP。终端向外发送Probe request报文，所述Probe request报文携带有所述Wi-Fi AP 的SSID，Wi-Fi AP接收到该Probe request报文，会向终端发送Probe response(探测响应)报文，所述Probe response报文携带有所述Wi-Fi AP的工作信道信息，终端可以根据所述Probe response报文获取所述Wi-Fi AP的工作信道。
本发明实施例提供了一种数据传输方法，所述方法包括：若终端接入的Wi-Fi AP的工作频段为第一频段，确定终端当前是否正在通过第一USB模式进行数据传输；所述第一USB模式为所述第一频段的干扰模式；若终端当前正在通过第一USB模式进行数据传输，切换至第二USB模式进行数据传输。相较于现有技术，可以根据终端当前Wi-Fi的工作频段和USB的工作状态切换USB的工作模式，避免终端USB模块对Wi-Fi信号产生干扰，提高了Wi-Fi信号的灵敏度，进而提高了Wi-Fi信号的通信质量。
本发明实施例提供一种数据传输方法，应用于手机，平板电脑，笔记本电脑，路由器等同时支持USB3.0和Wi-Fi的终端，如图2所示，所述数据传输方法包括：
步骤201、终端开机并加载Wi-Fi模块和USB模块，执行步骤202。
示例的，通常终端的Wi-Fi模块默认支持2.4GHz和/或5GHz频段，且所述Wi-Fi模块作为Wi-Fi station(站点)可以工作在2.4G或5G频段。所述2.4GHz频段指的是Wi-Fi联盟规定的ch1-ch13，即2412MHz-2472MHz频段。所述5GHz频段指的是Wi-Fi联盟规定的5150-5250MHz，5250-5350MHz，5470-5725MHz以及5725-5825MHz。
所述终端的USB模块默认的通信模式为USB3.0模式，所述USB3.0具有传统USB技术的易用性和即插即用功能，其实际传输速率大约是3.2Gbps(即320MB/S)，且具有后向兼容标准，即同时兼容USB1.1模式和USB2.0模式。
所述USB3.0模式表示终端硬件和软件支持USB3.0规范，终端在超高速(2.4G-2.5GHz)传输的最大传输带宽高达5.0Gbps(500MB/s)。USB2.0模式表示终端硬件和软件支持USB3.0规范，但仅采用低频传输最大传输带宽为480Mbps(即60MB/s)，所以USB2.0模式不会对Wi-Fi的2.4G频段产生干扰。同理，USB1.1模式也不会对Wi-Fi的2.4G频段产生干扰。
步骤202、终端扫描Wi-Fi AP列表中的每个Wi-Fi AP，获取每个Wi-Fi AP的工作信道，执行步骤203。
示例的，所述Wi-Fi AP列表包括多个Wi-Fi AP，所述多个Wi-Fi AP可以是初始化时预设的Wi-Fi AP，也可以是终端接入Wi-Fi的历史记录中的多个Wi-Fi AP。
可选的，终端可以通过监听Wi-Fi AP列表中每个Wi-Fi AP发送的Beacon报文，对Wi-Fi AP进行扫描并获取工作信道。以第一Wi-Fi AP为例进行说明，所述第一Wi-Fi AP为Wi-Fi AP列表中任意一个Wi-Fi AP。第一Wi-Fi AP在工作的过程中，会定时向外发送Beacon报文，所述Beacon报文中携带有第一Wi-Fi AP的SSID以及第一Wi-Fi AP的工作信道信息，终端可以根据所述Beacon报文获取所述第一Wi-Fi AP的工作信道。如果所述Wi-Fi AP列表为空，终端可以监听外部所有Wi-Fi AP发送的报文，并获取能够接收到报文的每个Wi-Fi AP的工作信道。
可选的，终端也可以通过802.11协议的Probe request(探测请求)报文主动扫描所述Wi-Fi AP。以第二Wi-Fi AP为例进行说明，所述第二Wi-Fi AP为终端搜索到的任意一个 Wi-Fi AP。终端向外发送Probe request报文，所述Probe request报文携带有所述第二Wi-Fi AP的SSID，若是其他Wi-Fi AP接收到该Probe request报文，则丢弃该报文，若是所述第二Wi-Fi AP接收到该Probe request报文，会向终端发送Probe response(探测响应)报文，所述Probe response报文携带有所述第二Wi-Fi AP的工作信道信息，终端可以根据所述Probe response报文获取所述第二Wi-Fi AP的工作信道。
这里介绍一下IEEE 802.11协议中的报文格式，如图3所示，IEEE 802.11协议规定802.11帧分为三个部分：Mac header 301(帧头)、Frame body 302(帧实体)、FCS(Frame Check Sequence，帧校验序列)域303。
所述帧头301包括五个部分，分别为Frame Control(帧控制)，Duration(持续时间)，Address 1(地址)，SA(Server Agent，服务代理商)，BSSID(Basic Service Set Identifier，基本服务集标识符)，Sequence Control(序列控制)。其中，如图4所示。所述Frame Control包括多个字段，分别为Protocol Version(协议版本)401、Type(类型)402、Subtype(子类型)403、To DS(上行帧)404、From DS(下行帧)405、More fragments(分段标志)406、Retry(重传)407、Power management(电源管理)408、More data(更多数据)409、Protected Frame(保护框架)410、Order(秩序)411。通常所述Type 402与Subtype 403字段用来指定使用的帧类型。
实际应用中，802.11无线局域网的报文分为三种：管理帧、控制帧和数据帧。以管理帧为例进行说明，所述管理帧包括多个报文，如表1所示，表1列举了所有涉及到管理帧的报文。
表1与管理帧相关的报文
Figure PCTCN2017079849-appb-000001
所述第二Wi-Fi AP的SSID和工作信道信息存储在管理帧的Beacon报文和Probe request或Probe response报文中，终端通过解析Beacon报文或Probe response报文获取第二Wi-Fi AP 的SSID和工作信道信息。
步骤203、终端根据每个Wi-Fi AP的工作信道，获取每个Wi-Fi AP的工作频段，执行步骤204。
示例的，终端可以通过判断当前Wi-Fi AP的工作信道属于哪个频段区间获取Wi-Fi AP的工作频段。具体地，如果AP的工作信道属于2412MHz-2472MHz频段，则Wi-Fi AP的工作频段是2.4GHz；如果AP的工作信道属于5150-5250MHz、5250-5350MHz、5470-5725MHz或5725-5825MHz，则Wi-Fi AP的工作频段是5GHz；如果当前外部Wi-Fi AP的工作信道属于其他频段，则Wi-Fi AP的工作频段是非法的，不在本发明的处理范围。
步骤204、终端根据每个Wi-Fi AP的工作频段，选择接入的Wi-Fi AP，执行步骤205。
可选的，终端可以根据每个Wi-Fi AP的工作频段和预设策略，选择接入的Wi-Fi AP，所述预设策略可以为终端优先接入5G频段的Wi-Fi AP。具体的，如果当前存在2.4G和5G频段多个可连接的Wi-Fi AP，终端优先连接5G频段的Wi-Fi AP，如果所有5G频段的Wi-Fi AP连接失败，则继续连接2.4G频段的Wi-Fi AP；如果终端仅支持2.4G频段，不支持5G频段，则连接外部2.4G频段Wi-Fi AP。终端还可以根据Wi-Fi AP优先级或信号强度选择接入的Wi-Fi AP，本发明在此不做赘述。
步骤205、若终端接入的Wi-Fi AP的工作频段为2.4GHz，确定终端当前是否正在通过USB3.0模式进行数据传输；若终端当前正在通过USB3.0模式进行数据传输，执行步骤206；若终端当前未通过USB3.0模式进行数据传输，执行步骤207。
示例的，如果当前终端接入的Wi-Fi AP的工作频段为2.4G Hz，说明终端当前的Wi-Fi可能会被USB3.0模式干扰，但是如果此时终端并没有通过USB3.0模式进行数据传输，即便终端当前USB模块的设置为USB3.0模式，也不会对Wi-Fi信号造成干扰，此时对USB模块传输模式的切换是无意义的。因此在当前终端接入的Wi-Fi AP的工作频段为2.4G Hz时，可以进一步判断终端USB模块是否正在通过USB3.0模式进行超高速数据传输。
可选的，可以通过判断外部USB设备是否支持USB3.0工作模式和外部USB设备是否与终端USB模块进行数据，判断当前终端USB模块是否进行超高速数据传输。
步骤206、终端将USB的通讯模式切换为USB2.0模式，本流程结束。
示例的，如果终端接入的Wi-Fi AP的工作频段为2.4GHz，且终端当前正在通过USB3.0模式进行数据传输，则Wi-Fi信号肯定会受到USB3.0模式的干扰，为了避免干扰，可以将USB的通讯模式从USB3.0模式切换为USB2.0模式，由于USB 2.0模式的数据传输速率较小，因此不会对Wi-Fi产生干扰。
较佳的，可以通过软件控制流程将USB的通讯模式切换为USB2.0模式，使得切换过程方便快捷，占用资源较少。
步骤207、终端保持当前USB的通讯模式不变。
示例的，如果终端接入的Wi-Fi AP的工作频段为2.4GHz，但终端当前并没有通过USB3.0模式进行数据传输，则无论终端的USB模块当前处于USB2.0模式还是USB3.0模式，终端均可以保持当前USB的通讯模式不变，避免做无意义的切换，造成处理资源的浪费。
具体的，如果当前终端Wi-Fi模块的工作频段为空或5G频段，则终端可以一直将USB模块设置为USB3.0模式。
需要说明的是，本发明实施例提供的数据传输方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本发明的保护范围之内，因此不再赘述。
