步骤11，在目标无线连接的扫描过程中，接收第一设备基于所述目标无线连接发送的链路信息。
在具体实施中，对于用户设备之间建立无线连接时，需要先进行扫描和发现过程，才能启动后续的连接流程的用户设备，在目标无线连接的扫描过程中，可以接收第一设备基于目标无线连接发送的链路信息。
在具体实施中，链路信息中可以包括第一设备的目标无线连接子设备信息以及第一设备的其他无线连接子设备信息，其中，目标无线连接子设备信息用于建立用户设备间的目标无线连接，其他无线连接子设备信息用于建立用户设备间的其他无线连接。
在具体实施中，目标无线连接子设备信息可以包括目标无线连接子设备的设备名称，也可以包括媒体存取控制位址(Media Access Control Address，MAC)地址、无线能力、工作频段等中的一种或多种。目标无线连接子设备信息所包括的具体内容，可以根据实际需求进行设定。其他无线连接子设备信息可以包括其他无线连接子设备的设备名称，也可以包括MAC地址、无线能力、工作频段等中的一种 或多种。
在本发明一实施例中，目标无线连接为WIFI，其他无线连接可以包括蓝牙，也可以包括其他在建立连接时需要先进行扫描及发现过程，才能连接的无线连接，此处不再一一举例说明。
在本发明另一实施例中，目标无线连接为蓝牙，其他无线连接可以包括WIFI，也可以包括其他在建立连接时需要先进行扫描及发现过程，才能连接的无线连接，此处不再一一举例说明。
在具体实施中，目标无线连接子设备与其他无线连接子设备可以位于第一设备的同一个无线通信芯片中，也可以位于不同的无线通信芯片中。当目标无线连接子设备与其他无线连接子设备位于不同的无线通信芯片中时，不同的无线通信芯片之间可以进行信息交互。
步骤12，从所述链路信息中，获取所述第一设备的所述目标无线连接子设备信息以及所述第一设备的其他无线连接子设备信息。
在具体实施中，当接收到链路信息后，可以从所述第一链路信息中获取目标无线连接子设备信息以及所述第一设备的其他无线连接子设备信息。
由上述方案可知，在目标无线连接扫描过程中，接收到的链路信息不仅包括目标无线连接子设备信息，还包括第一设备的其他无线连接子设备信息，其他无线连接子设备信息用于建立其他无线连接。从第一设备基于所述目标无线连接发送的链路信息，可以一并获取到第一设备的目标无线连接子设备信息以及其他无线连接子设备信息，以实现在完成目标无线连接扫描的过程中，可以一并获取到第一设备的目标无线连接子设备信息和其他无线连接子设备信息，而无需像现有技术一样再通过其他无线连接扫描来获取其他无线连接子设备信息。因此，相比现有技术中，完成同样种类的无线连接，本发明实施例提供的无线扫描方法可以减少扫描时间。其中，目标无线连接和其他无线连接是不同的无线连接，例如一个是蓝牙，另一个是WIFI。
在具体实施中，链路信息可以存在多种类型，例如，链路信息包括扫描请求响应帧，也即链路信息携带于扫描请求响应帧中。又如，当目标无线连接为WIFI时，链路信息包括信标管理帧，也即将链路信息携带于信标管理帧。链路信息的存在方式或携带方式与目标无线连接的类型相关。
参照图2，给出了本发明实施例中的另一种无线连接扫描方法的流程图。图2示出的无线连接扫描方法与图1所示出的无线连接扫描方法的基础上，当链路信息包括扫描请求响应帧时，在执行步骤11之前，无线连接扫描方法还可以包括如下步骤21。
步骤21，发送目标无线连接扫描请求。
在具体实施中，目标无线连接扫描请求中，可以包括第二设备的目标无线连接子设备信息以及第二设备的其他无线连接子设备信息。当第一设备接收到目标无线连接扫描请求时，向第二设备反馈链路信息，其中反馈的链路信息具体包括的信息可以根据目标无线连接扫描请求中携带的信息确定。当第一设备存在对应的其他无线连接时，第一设备则在向第二设备反馈的链路信息中携带目标无线连接子设备信息的同时，携带其他无线连接子设备信息。
例如，当目标无线连接为WIFI，WIFI扫描请求包括第二设备的WIFI子设备信息以及蓝牙子设备信息，当第一设备接收到WIFI扫描请求后，根据WIFI扫描请求中的蓝牙子设备信息，在链路信息中携带WIFI子设备信息的同时，也携带蓝牙子设备信息。
又如，目标无线连接为蓝牙，蓝牙扫描请求包括第二设备的蓝牙子设备信息以及第二设备的WIFI子设备信息，当第一设备接收到蓝牙扫描请求后，由于蓝牙扫描请求中的WIFI子设备信息，在链路信息中携带蓝牙子设备信息的同时，也携带WIFI子设备信息。
在本发明一实施例中，目标无线连接为WIFI，链路信息为信标管理帧。具体而言，两个WIFI设备连接前需要启动扫描过程，一个 WIFI设备作为WIFI无线接入点(Acess Point，AP)角色，另一个WIFI设备作为站点(station，STA)角色，AP定期广播信标管理帧(Beacon Frame)，其中Beacon Frame携带了AP中WIFI子设备信息，如无线AP节点名称(ssid)，无线能力(capability)等。STA也主动发起WIFI扫描请求(probe request)，WIFI扫描请求中包括WIFI子设备信息以及BT子设备信息。AP收到扫描请求后将AP的WIFI子设备信息(SSID、capability等)以及BT子设备信息(如，BT子设备名称、MAC地址等中的一种或多种)携带在请求响应帧(probe response)中，并将请求响应帧回复给STA。
对于可以作为热点或路由器的具有WIFI功能的用户设备，AP在定期广播信标管理帧携带WIFI子设备信息以及所支持的其他无线连接子设备信息(如BT子设备信息)。STA接收到AP定期广播的信标管理帧之后，可以获取AP的WIFI子设备信息以及BT子设备信息，从而实现在一次无线连接扫描过程中，同时发现多个无线连接子设备。
参照图3，给出了本发明实施例中的又一种无线连接扫描方法，具体可以包括如下步骤：
步骤33，在目标无线连接的扫描过程中，基于所述目标无线连接发送链路信息。
在具体实施中，链路信息可以包括：第一设备的目标无线连接子设备信息以及所述第一设备的其他无线连接子设备信息。第二设备接收到链路信息后，从链路信息中，获取第一设备的目标无线连接子设备信息以及第一设备的其他无线连接子设备信息。
在本发明一实施例中，目标无线连接为WIFI，其他无线连接包括蓝牙等无线连接。
在本发明另一实施例中，目标无线连接为蓝牙，其他无线连接包括WIFI等无线连接。
在具体实施中，当目标无线连接为WIFI时，基于目标无线连接发送的链路信息可以包括信标管理帧，也即链路信息携带于信标管理帧中。第一设备可以将信标管理帧通过定期广播的方式发送出去。
在具体实施中，无线连接扫描方法还可以包括如下步骤31及步骤32。
步骤31，接收目标无线连接扫描请求。
在具体实施中，目标无线连接扫描请求由第二设备发送，且所述目标无线连接扫描请求包括所述第二设备的目标无线连接子设备信息以及所述第二设备的其他无线连接子设备信息。
步骤32，根据所述目标无线连接扫描请求，生成所述链路信息。
在具体实施中，根据目标无线连接扫描请求中的其他无线连接子设备信息，当自身设备存在对应的其他无线连接子设备信息时，获取其他无线连接子设备信息。根据目标无线连接子设备信息以及其他无线连接子设备信息，生成链路信息。
由上可知，在目标无线连接扫描过程中，接收到的链路信息不仅包括目标无线连接子设备信息，还包括第一设备的其他无线连接子设备信息，其他无线连接子设备信息用于建立其他无线连接。从第一设备基于所述目标无线连接发送的链路信息，可以一并获取到第一设备的目标无线连接子设备信息以及其他无线连接子设备信息，以实现在完成目标无线连接扫描的过程中，可以一并获取到第一设备的目标无线连接子设备信息和其他无线连接子设备信息，而无需像现有技术一样再通过其他无线连接扫描来获取其他无线连接子设备信息。因此，相比现有技术中，完成同样种类的无线连接，本发明实施例提供的无线扫描方法可以减少扫描时间。其中，目标无线连接和其他无线连接是不同的无线连接，例如一个是蓝牙，另一个是WIFI。
