技术领域
本申请涉及通信技术领域，具体涉及一种获取天线组合的方法、电子设备和计算机可读存储介质。
背景技术
随着网络通信技术的快速发展，无线路由器被人们广泛的应用在工作和生活的场景中。无线路由器能够为覆盖范围内的终端设备提供无线保真(wireless fidelity，WIFI)网络，使得下挂的终端设备能够接入互联网。
常用的WIFI网络通常采用2.4G和5G两个频段进行通信。而WIFI-5G由于具有带宽大、速率高的特性，成为一些高速率场景下的首选，例如游戏场景、或者具有高速率要求的网络直播的场景等。但是，WIFI-5G相比WIFI-2.4G来说，由于频率高，绕射能力差，传播或者穿墙过程中，信号损耗较大，导致覆盖范围小。为了增大WIFI-5G的信号覆盖范围，通常在无线路由器中，除了设置全向天线之外，还会增设多个定向天线来增大WIFI-5G信号的覆盖范围，每个定向天线的高增益波束的指向不同，因此多个定向天线相互结合就能够使得高增益波束的覆盖范围更全面，使得无论下挂的终端设备位于无线路由器的哪个方向，都能够处于定线天线的高增益波束所覆盖的区域内，以此来保证WIFI-5G的通信质量。
但是当终端设备的使用状态发生变化时，例如终端设备的位置发生移动等情况，WIFI-5G的信号覆盖较弱无法正常通信的情况下，终端设备和无线路由器之间的网络连接可能会从WIFI-5G回退至WIFI-2.4G。在终端设备的高速率场景的需求下，无线路由器则可以在下一个扫描周期来临时，选择不同于上次的定向天线来和终端设备重新建立WIFI-5G的通信。但如果此时终端设备并不在所选择的定向天线的高增益波束所覆盖的扇区内，则建立WIFI-5G的通信可能会失败，那么网络连接就会被重新切换回WIFI-2.4G。无线路由器则在下一个扫描周期来临时，继续采用另外的定向天线来尝试建立WIFI-5G的通信，直至WIFI-5G的通信建立成功或者轮巡完所有的定向天线为止。
然而，无线路由器不断尝试采用不同的定向天线来建立WIFI-5G的通信的方式，使得网络连接不断地在WIFI-5G和WIFI-2.4G之间切换，无法及时选择合适的定向天线来建立WIFI-5G的网络连接进行通信，影响用户的体验。
发明内容

该方法中，无线路由器无需毫无依据地选择天线组合来将网络连接切换至第一连接，而是通过频率低的第二连接获取表征频率高的第一连接的通信质量的第一信号质量数据，然后根据第一信号质量数据来确定目标天线组合。之后无线路由器可以采用所确定的目标天线组合中的天线来收发第一频段的信号并建立第一连接进行通信。该方法能够避免由于天线组合选择不当导致的网络连接直接向第一连接进行切换时，连接失败导致的网络中断的问题，也进一步避免了网络连接在第一连接和第二连接之间来回跳转，无法及时对准高增益波束以及无法及时建立第一连接的问题，在网络连接切换至第一连接之前就先确定好符合通信要求的目标天线组合，能够使得网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。
在一些可能的实现方式中，第一信号质量数据用于表征通过第一天线组合采用第一连接通信时的通信质量，根据第一信号质量数据确定目标天线组合，包括：若第一信号质量数据满足预设通信要求，则确定第一天线组合为目标天线组合。

无线路由器可以通过第一天线组合发射信号所获取的第一信号质量数据满足预设通信要求时，确定第一信号质量数据对应的第一天线组合为目标天线组合，并依据第一信号质量数据所表征第一天线组合在第一频段通信时的通信质量满足通信需求，才确定第一信号质量数据对应的第一天线组合为目标天线组合。如果第一信号质量数据不能满足预设通信需求，则继续获取第二天线组合对应的第二信号质量数据，直至获取到满足预设通信需求的信号质量数据，并将满足预设通信需求的信号质量数据对应的天线组合作为目标天线组合，因此无需毫无依据地选择天线组合来建立新的网络连接，能够避免由于天线组合选择不当导致的网络连接直接向第一连接进行切换时，连接失败导致的网络中断的问题，也进一步避免了网络连接在第一连接和第二连接之间来回跳转，无法及时对准高增益波束以及无法及时建立第一连接的问题，在网络连接切换至第一连接之前就先选择好符合通信要求的目标天线组合，能够使得网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。
在一些可能的实现方式中，第一信号质量数据包括多组信号质量子数据，多组信 号质量子数据和多种天线组合一一对应，每组信号质量子数据表征通过对应的天线组合采用第一连接通信时的通信质量，根据第一信号质量数据确定目标天线组合，包括：从多组第一信号质量子数据中选出满足预设通信要求的目标信号质量子数据，目标信号质量子数据对应的天线组合为目标天线组合。
该方法可以获取多个天线组合对应的多组信号质量子数据，然后从中筛选符合要求的一组，并根据所选定的符合要求的目标信号质量子数据来指示目标天线组合，无需毫无依据地选择天线组合来建立新的网络连接，能够避免由于天线组合选择不当导致的网络连接直接向第一连接进行切换时，连接失败导致的网络中断的问题，也进一步避免了网络连接在第一连接和第二连接之间来回跳转，无法及时对准高增益波束以及无法及时建立第一连接的问题，在网络连接切换至第一连接之前就先选择好符合通信要求的目标天线组合，能够使得网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。
在一些可能的实现方式中，从多组第一信号质量子数据中选出满足预设通信要求的目标信号质量子数据，包括：从多组信号质量子数据中选出表征通信速率最高的一组作为目标信号质量子数据。
该方法可以多组信号质量子数据选择出最优的一组作为目标信号质量子数据，使得所确定的目标天线组合为最优的天线组合，确保通信质量最佳。
在一些可能的实现方式中，预设通信要求包括：通信速率大于或等于预设速率阈值，从多组第一信号质量子数据中选出满足预设通信要求的目标信号质量子数据，包括：从多组信号质量子数据中选出任一表征通信速率大于或等于预设速率阈值的一组作为目标信号质量子数据。
该方法可以在遍历判别信号质量子数据时，以最快的速度查找到满足预设通信要求的数据，相比全部查找能够节约时间，提高了天线切换的效率。
在一些可能的实现方式中，通过第二连接获取第一信号质量数据，包括：当通过第二连接所连接的设备为核心设备时，通过第二连接获取第一信号质量数据，核心设备为具有高增益波束需求的设备。
无线路由器先判断通过第二连接所连接的设备是否为核心设备，如果是核心设备，则表明该设备为具有高增益波束需求的终端设备，例如终端设备当前的使用场景为运行低延迟的游戏应用程序、或者网络直播应用程序，无线路由器可以确定此时需要在高增益波束对准的状态下切换至高频率的第一连接来建立高速率、低延迟的通信通道，就启动获取第一信号质量数据的步骤。如果终端设备并非核心设备，没有高增益波束需求，则无线路由器和终端设备之间使用低频率的第二频段，例如WIFI-2.4G的频率进行通信也能够满足通信需求，因此无需执行获取第一信号质量数据的步骤，也就无需切换网络连接，可以节约系统开销。
在一些可能的实现方式中，通过第二连接获取第一信号质量数据，包括：接收来自所连接的设备的天线切换请求；响应于天线切换请求，通过第二连接获取第一信号质量数据。
该方式可以在高增益波束没对准的时候通过所连接的设备主动发起流程这样的闭环反馈的模式，不用等待无线路由器周期性的触发流程才能切换至第二连接的网络， 减少了等待时间，使得网络切换更高效，提高了用户体验。
在一些可能的实现方式中，第一频段为WIFI的5G频段，第二频段为WIFI的2.4G频段。该方法能够在网络连接切换至WIFI-5G之前，通过WIFI-2.4G的网络先回传表征WIFI-5G的通信质量的信号质量数据，并预先确定好符合通信要求的目标天线组合，然后才进行网络连接的切换，使得网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表 示A或B；本文中的“和/或”仅仅是一种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这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括一个或者更多个该特征。
随着网络通信技术的快速发展，无线路由器被人们广泛的应用在工作和生活的场景中。无线路由器能够为覆盖范围内的终端设备提供WIFI网络，使得下挂的终端设备能够接入互联网。
常用的WIFI网络通常采用2.4G和5G两个频段进行通信。WIFI-2.4G的频率低，绕射能力强，在传播过程中或穿墙时，信号损失较少，覆盖范围交大。而WIFI-5G由于频率较高，电磁环境较为干净，因此在空间中受到的干扰较少，同时具有信道多、带宽大、速率高的特性，成为一些高速率场景下的首选，例如游戏场景，或者具有高速率要求的网络直播的场景等。但是，WIFI-5G相比WIFI-2.4G来说，由于频率高，绕射能力差，传播或者穿墙过程中，信号损耗较大，导致覆盖范围小。本申请中的WIFI-5G并不单指5GHz这个频点的频率，而是包括WIFI-5G的所有信道的对应的频率；WIFI-2.4G并不单指2.4GHz这个频点的频率，是包括了WIFI-2.4G的所有信道的对应的频率。
为了增大WIFI-5G的信号的覆盖范围，通常在无线路由器中除了设置全向天线之外，还会增设多个定向天线来增大WIFI-5G信号的覆盖范围。其中，全向天线为天线四周的增益较为均匀的天线，定向天线为固定的方向增益高、而其他方向增益低的天线。无线路由器中的每个定向天线的高增益波束的方向不同，因此多个定向天线相互结合就可以使得高增益波束的方向覆盖更全面。
图1为一例包括定向天线和全向天线的无线路由器100的示意图。图1中的无线路由器100以包括四个全向天线和三个定向天线为例示出，具体包括：全向天线101、全向天线102、全向天线103和全向天线104，定向天线105、定向天线106和定向天线107。通常，这四个全向天线可以用来收发WIFI-2.4G的信号，也可以用来收发WIFI-5G的信号。四个全向天线和三个定向天线都可以用来收发WIFI-5G的信号，并且三个定向天线在设置的时候，通常将不同的定向天线的高增益波束分别朝向不同的方向，能够使得高增益波束覆盖无线路由器100四周360度的范围。从而使得无论无线路由器100下挂的终端设备200位于无线路由器100的哪个方向，都能够处于一个定线天线的高增益波束所覆盖的区域内，以此来保证WIFI-5G的通信质量。无线路由器100可以自由选择使用哪几个全向天线和哪几个定向天线进行组合，来进行WIFI-5G的通信。
如图2所示，定向天线和全向天线各自的方向图如虚线所示，每个定向天线的高增益波束能够覆盖一个扇区(扇形的区域，图2中以将无线路由器周围的区域划分为扇区1、扇区2和扇区3为例)。当终端设备200的位置处于定向天线106的高增益波束所覆盖的扇区2时，无线路由器100可以选择全向天线103、全向天线104和定向天线106来收发WIFI-5G的信号。当终端设备200的位置发生变化，WIFI-5G的信号 变得很弱的时候，终端设备200和无线路由器100之间的网络连接可能会从WIFI-5G回退WIFI-2.4G，来保证不断连。但是基于高速率场景的需求，无线路由器100和终端设备200之间还是希望继续使用WIFI-5G进行通信。因此，无线路由器100可以在下一个扫描周期来临时，切换不同的定向天线来和终端设备200重新建立WIFI-5G的通信，例如选择全向天线103、全向天线104和定向天线105的组合来收发WIFI-5G的信号。但如果此时终端设备200并没有移动至定向天线105的高增益波束对应的扇区1内，那么无线路由器100选择全向天线103、全向天线104和定向天线105来收发WIFI-5G的信号时，则有可能由于信号弱无法建立WIFI-5G的通信，网络就会中断。此时，终端设备200和无线路由器100之间的网络连接会重新切换回WIFI-2.4G。无线路由器100则在下一个扫描周期来临时，继续切换其他的定向天线，例如将定向天线切换为定向天线107来尝试建立WIFI-5G的通信，由于终端设备200正好移动到定向天线107的高增益波束对应的扇区3内，WIFI-5G的通信可以建立成功。本申请中，我们将终端设备200位于一个定向天线的高增益波束对应的扇区内且选择这个定向天线来收发信号的过程，称为高增益波束对准的过程。可选地，上述定向天线可以采用包括水平极化和垂直极化方式的双极化天线。
然而，无线路由器100不断尝试采用不同的定向天线来建立WIFI-5G的通信的方式，使得网络连接不断地在WIFI-5G和WIFI-2.4G之间切换，无法及时选择合适的定向天线来建立WIFI-5G的网络连接进行通信，影响用户的体验。
本申请实施例提供的获取天线组合的方法可以应用于路由器、手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等设备，还可以应用在前文所述的无线路由器等网络设备上，本申请实施例对设备的具体类型不作任何限制。
可以理解的是，本申请实施例示意的无线路由器100的结构并不构成对网络设备的具体限定。在本申请另一些实施例中，无线路由器100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
为了便于理解，本申请以下实施例将以具有图1所示结构的无线路由器为例，结合附图和应用场景，对本申请实施例提供的获取天线组合的方法进行具体阐述。
图3为本申请实施例提供的一例无线路由器获取天线组合的方法的流程示意图。该方法包括：
S301、当网络连接为第二连接时，通过第二连接获取第一信号质量数据，第一信号质量数据用于表征采用第一连接通信时的通信质量，第一连接为采用第一频段进行通信的网络连接，第二连接为采用第二频段进行通信的网络连接，第一频段的频率高于第二频段的频率。
可选地，第一频段的频率高于第二频段的频率，可以是第一频段的所有频率高于第二频段的所有频率；也可以是第一频段的一部分频率高于第二频段的所有频率，第一频段的另一部分频率和第二频段的一部分频率重合，对此不做限定。
通常，当无线路由器接入互联网后，附近的终端设备，例如智能手机可以通过连 接无线路由器来访问互联网。无线路由器和智能手机之间可以采用WIFI-5G或者WIFI-2.4G的网络进行通信。本申请实施例中，以第一频段为WIFI-5G的频段，第二频段为WIFI-2.4G的频段为例，对无线路由器获取天线组合的方法进行描述。
在无线路由器和智能手机之间使用WIFI-5G的频段进行通信的过程中，如果智能手机的使用场景发生变化，例如位置发生快速移动导致多径环境发生变化，使得WIFI-5G的信号暂时覆盖较弱，无法正常使用WIFI-5G的网络进行通信时，无线路由器和智能手机之间会由频率高的WIFI-5G的网络连接切换为频率低的WIFI-2.4G的网络连接，保持通信连接。
在一些场景下，智能手机需要高速率通信，无线路由器需要重新和智能手机建立WIFI-5G的网络连接。本申请的实施例中，无线路由器并不直接从WIFI-2.4G向WIFI-5G的网络连接进行切换，而是继续保持WIFI-2.4G的网络连接的状态，同时挑选一组天线组合来测试这组天线进行WIFI-5G通信时的信号质量。
具体可以包括：无线路由器可以采用一组天线组合，以广播的形式发送WIFI-5G的频段的训练数据包，当智能手机接收到训练数据包后，可以获取这个训练数据包对应的第一信号质量数据，然后通过WIFI-2.4G的网络连接将本次测量的信号质量数据回传至无线路由器。当然，如果智能手机接收不到对应的训练数据包，则可以通过WIFI-2.4G的网络连接返回空值(null)。
本申请实施例中，无线路由器采用一组天线组合，通过WIFI-5G的频率广播训练数据包后，再通过WIFI-2.4G的网络连接回传表征WIFI-5G的信号质量优劣的信号质量数据，称作这组天线组合对应的信号质量数据。
可选地，该步骤S301可以是在终端设备需要和无线路由器建立高速率的第二连接、例如WIFI-5G的网络连接时触发，也可以是在网络连接由高速率的第一连接切换为低速率的第二连接时触发，例如WIFI-5G断开连接、网络连接切换至WIFI-2.4G时触发WIFI-5G的重连流程，即执行S301的步骤。
需要说明的是，上述信号质量数据能够反映通信质量的优劣。可选地，信号质量数据可以包括但不限于：CSI、RSSI、误码率(BER)、丢包率(PER)、通信速率和时延等等的数据中的任意一种或多种的结合，只要是能够反映采用所选的天线组合收发WIFI-5G信号时的通信质量即可。
在一些实施例中，无线路由器的存储器中可以预先存储多个天线组合的列表，每个天线组合均可以用来同时收发WIFI-5G的信号。例如每组天线组合中包括一个或多个全向天线和一个或多个定向天线。每组天线组合中的天线的个数可以根据无线路由器的产品规格来确定，本申请实施例对此并不做限定。例如，无线路由器的射频通路最多支持四路信号的收发时，则天线组合中的天线的个数最多可以为四个。
无线路由器可以从上述多个天线组合的列表中选择任一组天线组合来广播训练数据包，然后通过WIFI-2.4G的网络连接来接收智能手机反馈的训练数据包的信号质量数据。
S302、根据第一信号质量数据确定目标天线组合；其中，目标天线组合为网络连接由第二连接切换为第一连接进行通信时，收发第一频段的信号所调用的天线的组合形式。
当无线路由器获取到某一组天线组合对应的第一信号质量数据满足预设通信要求时，无线路由器则可以使用这一组天线组合进行WIFI-5G的通信能够满足通信速率、时延等要求，则可以将第一信号质量数据对应的这组天线组合作为目标天线组合。
无线路由器还可以将目标天线组合更新至天线的配置参数。之后，无线路由器可以调用这个目标天线组合对应的配置参数，然后控制相应的射频通路的开关进行切换，例如通过通用输入输出接口(general purpose input/output，GPIO)将控制指令发送至各射频通路上的开关，使得射频通路进行切换，打开这个目标天线组合中的各个天线所对应的射频通路，实现使用目标天线组合中的各个天线来收发第一频段的信号。例如图2所示的无线路由器确定出目标天线组合中包括全向天线101、全向天线103和定向天线107，则可以通过GPIO控制射频通路的开关逻辑，打开全向天线101、全向天线103和定向天线107的通路，采用全向天线101、全向天线103和定向天线107来收发第一频段的信号。例如图4所示，无线路由器通过GPIO控制开关切换，开关1为1-1和3-3导通、开关2为1-3导通。
图4中，WIFI芯片用于对WIFI信号进行调制解调，功率放大器(power amplifier，PA)为用于放大来自WIFI芯片的发射信号，低噪放(low noise amplifier，LNA)用于将来自天线的接收信号放大后，输入至WIFI芯片，PA所在的发射通路和LNA所在的接收通路通过单刀双掷开关(single pole double throw，SPDT)来切换。其中，PA1、PA3、PA5、PA7分别为2.4G通路1、2.4G通路2、2.4G通路3、2.4G通路4的发射通路上的PA，LNA1、LNA3、LNA5、LNA7分别为2.4G通路1、2.4G通路2、2.4G通路3、2.4G通路4的接收通路上的LNA；PA2、PA4、PA6、PA8、PA9分别为5G通路1、5G通路2、5G通路3、5G通路4和5G通路5的发射通路上的PA，LNA2、LNA4、LNA6、LNA8和LNA9分别为5G通路1、5G通路2、5G通路3、5G通路4和5G通路5的接收通路上的LNA；SPDT1用于切换2.4G通路1和5G通路1，SPDT2用于切换2.4G通路2和5G通路2，SPDT3用于切换2.4G通路3和5G通路3，SPDT4用于切换2.4G通路4和5G通路4，SPDT5用于切换2.4G通路1的收发通路，SPDT6用于切换5G通路1的收发通路，SPDT7用于切换2.4G通路2的收发通路，SPDT8用于切换5G通路2的收发通路，SPDT9用于切换2.4G通路3的收发通路，SPDT10用于切换5G通路3的收发通路，SPDT11用于切换2.4G通路4的收发通路，SPDT12用于切换5G通路4的收发通路，SPDT13用于切换5G通路5的收发通路。
可选地，S302的其他的实现方式还可以参见图5和图6所示的实施例，此处暂不赘述。
在图3所示的实施例中，无线路由器无需毫无依据地选择天线组合来将网络连接切换至第一连接，而是通过频率低的第二连接获取表征频率高的第一连接的通信质量的第一信号质量数据，然后根据第一信号质量数据来确定目标天线组合。之后无线路由器可以采用所确定的目标天线组合中的天线来收发第一频段的信号并建立第一连接进行通信。该方法能够避免由于天线组合选择不当导致的网络连接直接向第一连接进行切换时，连接失败导致的网络中断的问题，也进一步避免了网络连接在第一连接和第二连接之间来回跳转，无法及时对准高增益波束以及无法及时建立第一连接的问题，在网络连接切换至第一连接之前就先确定好符合通信要求的目标天线组合，能够使得 网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。
可选地，上述第一信号质量数据可以表征通过第一天线组合采用第一连接通信时的通信质量时，该方法具体如图5所示，包括：
S501、通过第二连接获取第一信号质量数据。其中，第一信号质量数据表征采用第一天线组合通过第一连接通信时的通信质量时，第一天线组合为第一连接能够使用的多个天线组合形式中的一种，该第一天线组合中可以包括至少一个定向天线。
S502A、若第一信号质量数据满足预设通信要求，则确定第一天线组合为所述目标天线组合。
无线路由器可以判断第一信号质量数据是否满足预设通信要求，如果满足，则表示第一天线组合采用第一天线组合进行通信时，通信质量能够满足通信需求，则可以确定将第一天线组合作为目标天线组合，来收发第一频段的信号。
例如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的CSI，则无线路由器如果判断第一天线组合中的每个天线对应的CSI的信号幅度均大于或等于预设的幅度阈值，则无线路由器可以确定第一天线组合为目标天线组合。
再如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的误码率或丢包率，则无线路由器如果判断误码率或丢包率低于百分之十，例如为5％，就可以确定第一天线组合为目标天线组合。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的时延，且时延小于预设的时延阈值，则确定第一天线组合为目标天线组合。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的通信速率，且通信速率大于或等于预设的速率阈值，则确定第一天线组合为目标天线组合。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的误码率、丢包率和CSI中的两种或三种时，则无线路由器如果判断误码率、丢包率、CSI、RSSI、通信速率和时延中的多种的组合全部都能够满足对应的通信需求，例如第一天线组合中的每个天线对应的CSI的信号幅度均大于或等于预设的幅度阈值、误码率和丢包率低于百分之十、时延低于预设的时延阈值、且RSSI大于或等于预设的接收信号强度阈值、通信速率大于或等于预设的速率阈值，就可以确定第一天线组合为目标天线组合。
在一些实施例中，图5的实施例还可以包括：
S502B、若第一信号质量数据不满足预设通信要求，则通过第二连接获取第二信号质量数据，第二信号质量数据用于表征通过第二天线组合采用第一连接通信时的通信质量，第二天线组合和第一天线组合为不同的天线的组合形式。
第一天线组合和第二天线不同可以为第一天线组合中的天线和第二天线组合中的天线均不同，也可以是第一天线组合中的天线和第二天线组合中的天线部分相同部分不同，对此不做限定，两个天线组合中只要有一个不同的天线即为不同的天线组合。
具体的，如果第一信号质量数据不满足预设通信要求，则无线路由器可以继续通过下一组天线组合、例如第二天线组合，发送第一频段的信号，并通过第二连接获取对端的终端设备反馈的第二信号质量数据。上述第二天线组合和第一天线组合为不同的天线的组合形式，是指第二天线组合中所包括的天线和第一天线组合中所包括的天 线并不完全相同，可以是部分相同部分不同，也可以是完全不相同，对此并不做限定。
例如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的CSI，则无线路由器如果判断第一天线组合中的每个天线对应的CSI的信号幅度均小于预设的幅度阈值，则无线路由器可以确定采用第一天线组合并不能满足通信需求，因此可以继续获取下一组天线组合并获取对应的第二信号质量数据。
再如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的误码率或丢包率，则无线路由器如果判断误码率或丢包率大于或等于百分之十，例如为15％，就可以确定第一天线组合并不能满足通信需求，因此可以继续获取下一组天线组合并获取对应的第二信号质量数据。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的时延，且时延大雨或等于预设的时延阈值，则可以继续获取下一组天线组合并获取对应的第二信号质量数据。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的通信速率，且通信速率小于预设的速率阈值，则确定第一天线组合为目标天线组合。
又如，当第一信号质量数据为使用第一天线组合发送第一频段的信号的误码率、丢包率和CSI中的多种时，则无线路由器如果判断误码率、丢包率、CSI、RSSI、通信速率和时延中的多种的组合全部都能够满足对应的通信需求，例如第一天线组合中的每个天线对应的CSI的信号幅度存在小于预设的幅度阈值的数据、误码率和丢包率高于百分之十、时延大于或等于预设的时延阈值、且RSSI小于预设的接收信号强度阈值、通信速率小于预设的速率阈值，就可以确定第一天线组合并不能满足通信需求，因此可以继续获取下一组天线组合并获取对应的第二信号质量数据。
可选地，如果无线路由器在预设的时段内未接收到终端设备反馈的第一信号质量数据、或获取到的数据为空值(null)、或者获取到的第一信号质量数据(例如CSI)不完整时，则有可能是无线路由器广播的测试信号有误或信号太弱等原因，此时可以保持第二连接并重新返回执行步骤S501以便重新开始流程，避免流程中断导致无法切换至高速网络进行高速率通信的问题。
S503A、若第二信号质量数据满足预设通信要求，则确定第二天线组合为目标天线组合。
S503B、若第二信号质量数据不满足预设通信要求，则根据其他信号质量数据确定目标天线组合，其他信号质量数据用于表征采用其他天线组合通过第一连接通信时的通信质量，其他天线组合包括除第一天线组合和第二天线组合之外的天线的组合形式。
无线路由器继续判断第二信号质量数据是否满足预设通信要求，如果满足，则确定第二天线组合为目标天线组合。如果不满足则继续采用再下一组天线组合来发送测试信号并获取对应的信号质量数据，然后重复执行上述判断信号质量数据是否满足预设通信要求的过程，直至获取的信号质量数据满足预设通信要求为止，并可以将满足预设通信要求的信号数据质量对应的天线组合作为目标天线组合。
可选地，在此之前无线路由器还可以先判断连接的终端设备是否为核心设备，如果是核心设备，则表明该终端设备为具有高增益波束需求的终端设备，例如终端设备 当前的使用场景为运行低延迟的游戏应用程序、或者网络直播应用程序，无线路由器可以确定此时需要在高增益波束对准的状态下切换至高频率的第一连接来建立高速率、低延迟的通信通道，就启动获取第一信号质量数据的步骤。如果终端设备并非核心设备，没有高增益波束需求，则无线路由器和终端设备之间使用低频率的第二频段，例如WIFI-2.4G的频率进行通信也能够满足通信需求，因此无需执行获取第一信号质量数据的步骤，也就无需切换网络连接，可以节约系统开销。
可选地，上述核心设备也可以是具有特殊标识的终端设备，例如该终端设备的用户为重要客户，该特殊标识表征需要该终端设备通过高增益波束对准来优先保证通信的高速率和低延迟，本申请对核心设备的具体形式不做限定，只要是具有高增益波束需求的终端设备即可。
在上述图5所示的实施例中，无线路由器可以通过第一天线组合发射信号所获取的第一信号质量数据满足预设通信要求时，确定第一信号质量数据对应的第一天线组合为目标天线组合，并依据第一信号质量数据所表征第一天线组合在第一频段通信时的通信质量满足通信需求，才确定第一信号质量数据对应的第一天线组合为目标天线组合。如果第一信号质量数据不能满足预设通信需求，则继续获取第二天线组合对应的第二信号质量数据，直至获取到满足预设通信需求的信号质量数据，并将满足预设通信需求的信号质量数据对应的天线组合作为目标天线组合，因此无需毫无依据地选择天线组合来建立新的网络连接，能够避免由于天线组合选择不当导致的网络连接直接向第一连接进行切换时，连接失败导致的网络中断的问题，也进一步避免了网络连接在第一连接和第二连接之间来回跳转，无法及时对准高增益波束以及无法及时建立第一连接的问题，在网络连接切换至第一连接之前就先选择好符合通信要求的目标天线组合，能够使得网络连接一次性切换成功，实现高增益波束的快速对准，提高了天线切换的效率，也避免了网络中断，提升了用户体验。
在一个具体的实施例中，图5所示的实施例的具体的流程还可以参见图6的实施例，以无线路由器下挂一台终端设备，二者之间采用WIFI-2.4G或WIFI-5G进行通信，且信号质量数据为CSI为例，该方法具体包括：
S601、无线路由器监测到和终端设备之间的网络连接由WIFI-5G切换为WIFI-2.4G。
当终端设备的使用场景发生变化时，例如位置发生快速移动，离开当前所使用的定向天线覆盖的扇区，无线路由器和终端设备都能够检测到二者之间的网络连接由WIFI-5G切换为WIFI-2.4G。
在一些实施例中，无线路由器可能是周期性的监控网络连接的切换状态或者周期性的触发高增益波束指向遍历测试程序，则无线路由器获取信号质量数据也可以是相应于终端设备的请求所触发。例如终端设备监控到和无线路由器之间的网络连接由WIFI-5G切换为WIFI-2.4G，则可以通过WIFI-2.4G向无线路由器发送激活高增益波束指向遍历测试程序的请求或者天线切换请求，无线路由器基于这样的请求激活高增益波束指向遍历测试程序，从而实现高增益波束对准。这样可以在高增益波束没对准的时候通过终端设备主动发起流程这样的闭环反馈的模式，不用等待无线路由器周期性的触发流程才能切换至WIFI-5G的网络，减少了等待时间，使得网络切换更高效，提高了用户体验。
S602、无线路由器确定通过WIFI-2.4G的网络连接的设备是否为核心设备。
若是，则执行S603，若否，则结束流程。
即无线路由器下挂的终端设备为具有高速率需求的核心设备，例如核心设备此时正在运行低延迟的游戏应用程序，或者正在运行网络直播的应用程序。
S603、无线路由器激活高增益波束指向遍历测试程序，通过WIFI-2.4G的网络来获取WIFI-5G的频段对应的CSI。
高增益波束指向遍历测试程序包括：依次通过每一组天线组合发送WIFI-5G频段的训练数据包进行碰撞测试，并获取终端设备反馈的每一组天线组合对应的CSI。
例如，无线路由器选定一组天线组合并采用广播的方式发送WIFI-5G频段的训练数据包，终端设备则可以获取这个训练数据包对应的CSI，并将CSI通过WIFI-2.4G的网络连接回传至无线路由器。此时无线路由器获取到这组天线组合发送的训练数据包对应的CSI，则可以根据反馈的CSI来判决采用这组天线组合收发信号时，信号质量是否能够满足核心设备的通信需要。
在S603的执行过程中，WIFI-2.4G一直处于驻网状态。
S604、无线路由器判定CSI是否完整。
如果无线路由器获取到的CSI为空值或不完整，返回执行S603。如果CSI完整，则继续执行S605。
可选地，如果无线路由器获取到的CSI为空值(null)或不完整，则有可能是无线路由器广播的测试信号有误等原因，此时可以保持驻网在WIFI-2.4G的频率并重新返回执行步骤S602或S603以便重新开始流程，避免流程中断导致无法切换至高速网络进行高速率通信的问题。
S605、无线路由器判定CSI是否满足网络连接由WIFI-2.4G向WIFI-5G切换的条件。
若满足，则执行S606；若不满足，则返回执行S603。
S606、确定满足网络连接由WIFI-2.4G向WIFI-5G切换的条件的CSI对应的天线组合为目标天线组合。
例如，如果一个天线组合中的每个天线对应的CSI的信号幅度均大于或等于预设的幅度阈值，则无线路由器可以判定满足网络连接由WIFI-2.4G向WIFI-5G切换的条件，则可以将满足切换条件的CSI对应的天线组合为目标天线组合，并及时切换天线。
如果一个天线组合中的每个天线对应的CSI的信号幅度存在小于预设的幅度阈值的数据，则无线路由器可以判定不满足网络连接由WIFI-2.4G向WIFI-5G切换的条件，则有可能是当前终端设备距离无线路由器过远，如果终端设备的位置还在移动，可以继续返回执行S603，获取终端设备在新的场景下(例如新位置)对应的CSI并继续流程，直至网络切换成功。
图6所示的实施例的实现原理和有益效果可以参见前述实施例的描述，此处不再赘述。
在一些实施例中，无线路由器还可以是通过第二连接获取多组天线组合一一对应的多组信号质量子数据，然后在多组信号质量子数据中筛选出满足预设通信要求的目标信号质量子数据，并将目标信号质量子数据对应的天线组合作为目标天线组合。换 句话说，这多组信号质量子数据可以作为上述第一信号质量数据，以此来确定目标天线组合。
例如，无线路由器的存储器中存储有天线组合1、天线组合2和天线组合3，无线路由器先通过天线组合1中的天线发送训练数据包，并接收对应的第一CSI；然后通过天线组合2中的天线发送训练数据包，并接收对应的第二CSI；最后通过天线组合3中的天线发送训练数据包，并接收对应的第三CSI，然后从第一CSI、第二CSI和第三CSI中选出满足预设通信要求的一个，例如是第一CSI，将第一CSI对应的天线组合1作为最终的目标天线组合。
可选地，无线路由器可以是从多组信号质量子数据中任选一组满足预设通信要求的数据，例如从第一CSI、第二CSI和第三CSI中选出任意一组满足预设通信要求的数据，例如是选择出的CSI所表征通信速率大于或等于预设速率阈值，并将这个数据对应的天线组合作为最终的目标天线组合，可以在遍历判别信号质量子数据时，以最快的速度查找到满足预设通信要求的数据，相比全部查找能够节约时间，提高了天线切换的效率。
可选地，无线路由器也可以是将多组信号质量子数据进行比较，例如将第一CSI、第二CSI和第三CSI进行比较，从中选择出表征通信速率最高的一组对应的天线组合作为目标天线组合，并将这个CSI对应的天线组合作为目标天线组合。该方式可以选择出使得通信质量最优的天线组合，最大化的确保通信质量。
可选地，上述信号质量数据还可以包括CSI，关于如何根据CSI判断通信质量的过程，此处进行示例性的描述：
CSI能够描述信号在每条传输路径上的衰弱因子，即CSI可以包括信道增益矩阵中每个元素的值，如信号散射(scattering)、环境衰弱((fading)，包括多径衰弱和阴影衰弱(multipath fading or shadowing fading))、距离衰减(power decay of distance)等信息。CSI所携带的信息可以使通信系统调整来适应当前的信道条件，在多天线系统中为高可靠性高速率的通信提供了保障。
通常直接采集到的信道信息为信道频率响应(CFR，channel frequency response)，CFR的时域表现为信道脉冲响应(CIR，channel impulse response)，二者可以通过傅里叶变换和反变换实现互换。CSI是CFR的采样版本。
得到CFR数据后，可以通过数字信号处理方法，识别出特征信息。以多入多出(multiple-input multiple-output，MIMO)4*4的无线路由器为例，每个天线都具有各自的标记。图7中的a图和b图中的纵轴为幅度，横轴为偏离信号的中心频点的频偏量。图7中的a图中的四条曲线为四个天线分别对应的CRF的实部的数据，图7中的b图中的四条曲线为四个天线分别对应的CRF的虚部的数值。需要说明的是，将上述图7中的a图中的四条曲线进行采样，可以得到四个天线分别对应的CSI的实部的数据，例如图7中的a图中的四条曲线上的圆圈所示；将上述图7中的b图中的四条曲线进行采样，可以得到四个天线分别对应的CSI的虚部的数据，例如图7中的b图中的四条曲线上的圆圈所示。可选地，可以将图7中的a图中的CSI的数据取绝对值后，得到图8中的a图所示的四条曲线上的圆圈所示的CSI的实部的绝对值，之后就可以根据图8中的a图中的曲线的纵轴数值的大小来判断通信质量，哪个天线对应的数值 越大，则表明信号越好，哪个天线对应的数值越小，则表明信号越差。以图8中的a图为例，可以将CSI的幅度阈值设置为1000，大于或等于该幅度阈值的表示通信质量满足通信要求，小于该幅度阈值的表示通信质量不满足通信要求。可选的，还可以将CFR数据进行傅里叶反变换，得到如上述图7中的a图中的四条曲线在时域的数据，如图8中的b图所示，图8中的b图中纵轴数值越大表示信号的功率越强，信号质量越好，图8中的b图中纵轴数值越小表示信号的功率越弱，信号质量越差。以图8中的b图为例，可以将CIR的功率阈值设置为0.5×105，CIR大于或等于该功率阈值，表示通信质量满足通信要求，小于该功率阈值的表示通信质量不满足通信要求。
需要说明的是，上述图7和图8中，纵轴所表征的幅度和功率的数值并非幅度和功率的实际值，而是表示幅度大小和功率大小的归一化的数值，可以用来比较大小即可。
对于本申请来说，无线路由器可以通过综合判断天线组合中的多个天线的CSI的实部绝对值的大小来确定这个天线组合是否满足通信需求；或者是单独判断天线组合中定向天线对应的CSI的实部的绝对值的大小来确定这个天线组合是否满足通信需求；还可以是首先判断定向天线对应的CSI的实部绝对值的大小，再判断天线组合中其他的全向天线对应的CSI的实部绝对值的大小，对此本申请不做限定。需要说明的是，CSI的实部绝对值的大小比较时，可以是取一段频率内的平均值，也可以是取一段频率内的最大值，也可以取一段时间内连续多次获取的CSI的实部绝对值的累加后取平均值，具体不做限定。
