但是，上述无线投屏技术和文件分享功能实现的过程中，需要先建立蓝牙连接，再基于蓝牙连接建立两个电子设备之间的无线保真(wireless fidelity，Wi-Fi)直连，以进行数据交互。由于蓝牙连接性能及稳定性差的问题，会导致电子设备间建链时延较大，影响用户使用体验。
发明内容
本申请实施例提供的连接建立方法及电子设备，能够直接利用Wi-Fi网络实现在电子设备间建链，提高建链性能，提升用户使用体验。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种连接建立方法，应用于第一电子设备，该方法可以包括：获取第二电子设备的近场通信NFC标签中的第二电子设备无线保真Wi-Fi接口的媒体访问控制MAC地址。利用Wi-Fi接口的MAC地址，查询第二电子设备是否具有Wi-Fi参数协商能力。若第二电子设备具有Wi-Fi参数协商能力，则与第二电子设备进行Wi-Fi参数协商，获得目标射频参数。利用目标射频参数与第二电子设备建立Wi-Fi直连通道。
在一些实施例中，Wi-Fi参数协商能力例如包括Wi-Fi热点参数协商能力。电子设备具有Wi-Fi热点参数协商能力，能够进行无线投屏和/或跨设备文件分享。
在一些实施例中，第一电子设备和第二电子设备完成Wi-Fi参数协商后，利用目标射频参数建立Wi-Fi直连通道。其中，Wi-Fi直连通道例如包括Wi-Fi点对点连接通道或Wi-Fi二层网络连接通道。
在一些实施例中，NFC标签中包含NFC参数信息，通过扩展NFC标签，在NFC参数信息中直接指示Wi-Fi接口的MAC地址。
如此，基于NFC功能，第一电子设备能够直接在第二电子设备的NFC标签中获取第二电子设备Wi-Fi接口的MAC地址。第一电子设备利用该Wi-Fi接口的MAC地址与第二电子设备进行Wi-Fi参数协商，建立Wi-Fi直连通道，进行数据传输。相对于现有技术中的连接方法，不必先进行蓝牙连接，再基于蓝牙连接建立Wi-Fi直连通道。 避免出现由于蓝牙连接的性能及稳定性差造成的建链时延较大的问题，提高交互性能。
在一种可能的实现方式中，在获取第二电子设备的近场通信NFC标签中的第二电子设备无线保真Wi-Fi接口的媒体访问控制MAC地址之前，方法还包括：向AP设备发送注册请求，注册请求用于请求注册第一电子设备的第二能力信息，第二能力信息包含Wi-Fi参数协商能力。
在一种可能的实现方式中，第一电子设备和第二电子设备接入同一个无线访问接入点AP设备提供的Wi-Fi网络，利用Wi-Fi接口的MAC地址，查询第二电子设备是否具有Wi-Fi参数协商能力，包括：接收AP设备发送的设备列表信息，设备列表信息中包含接入AP设备的电子设备的能力信息。在设备列表信息中，查询Wi-Fi接口的MAC地址对应的第二电子设备的第一能力信息，确定第一能力信息中是否包含Wi-Fi参数协商能力。
在一种可能的实现方式中，第一电子设备和第二电子设备接入同一个无线访问接入点AP设备提供的Wi-Fi网络，利用Wi-Fi接口的MAC地址，查询第二电子设备是否具有Wi-Fi参数协商能力，包括：向AP设备发送能力查询请求，能力查询请求中携带Wi-Fi接口的MAC地址，能力查询请求用于请求查询第二电子设备是否具有Wi-Fi参数协商能力。接收AP设备发送的能力查询响应，能力查询响应用于指示第二电子设备是否具有Wi-Fi参数协商能力。
也就是说，第一电子设备和第二电子设备在接入AP设备提供的网络后，会向AP设备注册自身支持的能力。AP设备基于本地安全策略，将接入的电子设备在注册过程中注册的设备信息进行广播，同步给局域网内连接的各个电子设备。进而第一电子设备监听广播后，可以保存接入该AP设备的设备列表信息，基于该设备列表信息能够发现局域网内的邻设备。从而第一电子设备在接收到Wi-Fi接口的MAC地址后，能够发现邻设备中支持Wi-Fi参数协商能力的第二电子设备。或者，若第一电子设备在本地设备列表中未查询到该Wi-Fi接口的MAC地址对应的电子设备，则可以向AP设备发送查询请求，由AP设备进行查询，并接收AP设备发送的查询结果，进而获得第二电子设备的能力信息。
如此，第一电子设备通过上述方法，确定第二电子设备是否具备Wi-Fi参数协商能力，以确定第二电子设备是否支持进行无线投屏和/或跨设备文件分享。在确定第二电子设备支持Wi-Fi参数协商能力后，才请求进行Wi-Fi参数协商，建立Wi-Fi通信通道。
在一种可能的实现方式中，若第二电子设备具有Wi-Fi参数协商能力，则与第二电子设备进行Wi-Fi参数协商，获得目标射频参数；包括：向AP设备发送Wi-Fi参数协商请求，Wi-Fi参数协商请求中携带第二电子设备的标识以及第一射频参数；第一射频参数包括第一电子设备支持的射频频段中空闲的射频频段，以及第一电子设备支持的信道中空闲的信道。接收AP设备转发的第二电子设备发送的Wi-Fi参数协商响应，Wi-Fi参数协商响应中携带目标射频参数，目标射频参数包括第二电子设备从空闲的射频频段中选择的目标射频频段以及从空闲的信道中选择的目标信道。
在一些实施例中，第一电子设备确定与第二电子设备建立连接，则需要协商 Wi-Fi通道连接参数，以建立Wi-Fi直连通道，第一电子设备需要将自身支持且可用的射频参数发送至第二电子设备。但是，为了保证网络安全，AP设备设置了二层隔离，不允许第一电子设备与第二电子设备之间直接通信，而是由AP设备对第一电子设备与第二电子设备之间的信号进行转发，从而实现对接入AP设备网络的电子设备的权限和流量审计。因此，第一电子设备将自身可用的射频参数发送至AP设备，由AP设备基于Wi-Fi参数协商请求中携带的目标设备标识，将接收到的射频参数转发至相应的目标设备(即第二电子设备)。
在一些实施例中，第二电子设备在接收到第一电子设备发送的第一射频参数后，根据第一射频参数以及自身支持且当前可用的射频参数，选择最佳射频频段和信道，作为目标射频参数。比如，第二电子设备在自身和第一电子设备均支持且可用的射频频段和信道中选择预期信号质量最好的射频频段和信道。又比如，第二电子设备在自身和第一电子设备均支持且可用的射频频段和信道中选择时延最小的射频频段和信道。
在一种可能的实现方式中，若第二电子设备具有Wi-Fi参数协商能力，则与第二电子设备进行Wi-Fi参数协商，获得目标射频参数；包括：向第二电子设备发送Wi-Fi参数协商请求，Wi-Fi参数协商请求中携带第一射频参数；第一射频参数包括第一电子设备支持的射频频段中空闲的射频频段，以及第一电子设备支持的信道中空闲的信道。接收第二电子设备发送的Wi-Fi参数协商响应，Wi-Fi参数协商响应中携带目标射频参数，目标射频参数包括第二电子设备从空闲的射频频段中选择的目标射频频段以及从空闲的信道中选择的目标信道。
在一些实施中，AP设备在局域网内未设置二层隔离，第一电子设备与第二电子设备之间能够直接进行通信。那么，在第一电子设备与第二电子设备进行Wi-Fi参数协商的过程中，则不需要利用AP设备转发用于协商的射频参数。
在一种可能的实现方式中，利用目标射频参数与第二电子设备建立Wi-Fi直连通道，包括：在目标射频频段和目标信道上发送连接建立请求，连接建立请求用于请求与第二电子设备建立Wi-Fi直连通道。接收第二电子设备发送的连接建立响应，完成Wi-Fi直连通道的建立。
在一些实施例中，第二电子设备在确定目标射频参数后，创建热点，将自身作为软接入点(soft AP)设备，配置射频接口的射频参数，以便后续第一电子设备能够接入该射频接口，传输数据。进一步的，第二电子设备作为soft AP设备基于目标射频参数，按照预设周期发送信标(beacon)帧。
相应的，第一电子设备接收到Wi-Fi参数协商响应后，确定Wi-Fi参数协商成功。按照协商确定的目标射频参数中指定的射频频段和信道，基于802.11协议发送探测请求(probe request)管理帧，用于搜索第二电子设备发送的beacon帧。在搜索到第二电子设备后，自动触发认证和关联流程，与第二电子设备创建Wi-Fi直连通道，进而开始进行数据的传输。
第二方面，本申请实施例提供一种连接建立方法，应用于第一电子设备，该方法可以包括：响应于第一操作，向无线接入点AP设备发送设备查询请求，设备查询请求用于请求查询具有Wi-Fi参数协商能力的设备。接收AP设备发送的设备 查询响应，设备查询响应携带第二电子设备无线保真Wi-Fi接口的MAC地址，第二电子设备具有Wi-Fi参数协商能力。利用Wi-Fi接口的MAC地址，与第二电子设备进行Wi-Fi参数协商，获得目标射频参数。利用目标射频参数与第二电子设备建立Wi-Fi直连通道。
在一种可能的实现方式中，在响应于第一操作，向无线接入点AP设备发送设备查询请求之前，方法还包括：向AP设备发送注册请求，注册请求用于请求注册第一电子设备的第二能力信息，第二能力信息包含Wi-Fi参数协商能力。
在一些实施中，第一电子设备和第二电子设备接入同一个AP设备提供的Wi-Fi网络中。在接入AP设备后，直接向AP设备注册自身支持的能力，及接口信息。如蓝牙接口信息，Wi-Fi接口信息等。进而后续，第一电子设备能够直接向AP设备查询具有Wi-Fi参数协商能力的设备以及该设备的Wi-Fi接口的MAC地址。
由此，不利用NFC参数信息，第一电子设备也可以获得第二电子设备的Wi-Fi接口的MAC地址，与第二电子设备基于Wi-Fi接口的MAC地址直接建立Wi-Fi直连通道，提高建链性能及稳定性，提升用户使用体验。
在一种可能的实现方式中，利用Wi-Fi接口的MAC地址，与第二电子设备进行Wi-Fi参数协商，获得目标射频参数；包括：向AP设备发送Wi-Fi参数协商请求，Wi-Fi参数协商请求中携带第二电子设备的标识以及第一射频参数；第一射频参数包括第一电子设备支持的射频频段中空闲的射频频段，以及第一电子设备支持的信道中空闲的信道。接收AP设备转发第二电子设备发送的Wi-Fi参数协商响应，Wi-Fi参数协商响应中携带目标射频参数，目标射频参数包括第二电子设备从空闲的射频频段中选择的目标射频频段以及从空闲的信道中选择的目标信道。

首先，为了便于理解，下面先对本申请实施例可能涉及的相关术语和概念进行介绍。
(1)Huawei Hilink
Huawei Hilink为一种智能硬件开放生态，电子设备能够通过硬件接入或云接入等方式加入到Huawei Hilink生态中，实现电子设备互联互通。
在一些实施例中，Hilink生态也可以描述为智联网络，智联网络包括一个用于提供无线网络的无线访问接入点(access point，AP)设备，以及至少一个接入AP设备的电子设备。其中，AP设备例如为

在一些实施例中，PC中包括射频识别(radio frequency identification，RFID)模块，手机开启NFC功能，靠近PC的NFC感应区域，可读取PC的NFC参数信息，如NFC标签中的参数信息，获得PC Wi-Fi接口的MAC地址。其中，NFC参数信息中的Wi-Fi接口的MAC地址可以预配置于PC的NFC标签中。或者，在PC开机启动某应用程序激活Wi-Fi接口时，再将Wi-Fi接口的MAC地址写入NFC标签。
示例性的，NFC标签中的数据以NFC数据交换格式(NFC data exchange format，NDEF)报文(message)形式保存。其中，每条报文可由多条记录(Record)(也可以描述为多个子包)构成。例如，如图8所示，示例性的给出一种报文格式。其中，NDEF报文包括包头子包，NDEF Record 0子包以及NDEF Record 1子包。
其中，NDEF Record 0子包，用于保存统一资源定位系统(uniform resource locator，URL)。该URL可以打开当前使用NFC功能的应用的网站，进而获得该应用的介绍。例如，假设手机通过碰触PC NFC感应区域待传输数据，且手机不支持“一碰传”功能。该URL指向介绍一碰传功能的网站，手机在触碰PC NFC感应区域时，手机通过该URL显示对应网站，以便用户查看相关介绍。
NDEF Record 1子包，用于保存NFC参数信息。如图8所示，NDEF Record 1子包包括位标记(bit flag)字段、类型长度(type length)字段、净荷长度(payload length)字段、ID长度(ID length)字段、净荷类型(payload type)字段、净荷ID(payload ID)字段、以及净荷数据(payload data)字段。
其中，净荷数据字段，占用的字节数量为变量，可以根据子字段数据长度变化。净荷数据字段包括版本号子字段、蓝牙接口MAC地址子字段、Wi-Fi接口MAC地址子字段、随机数子字段、型号子字段、以及子型号子字段。
蓝牙接口MAC地址子字段，占用6个字节(byte)，用于指示PC的蓝牙接口的MAC地址。手机可以基于该MAC地址与PC建立蓝牙连接。
Wi-Fi接口MAC地址子字段，占用6个字节，用于指示PC的Wi-Fi接口的MAC地址。手机可以基于该MAC地址与PC建立Wi-Fi连接。如此，通过扩展NFC标签，在NFC参数信息中直接指示Wi-Fi接口的MAC地址，从而使得手机和PC不必再建立蓝牙连接的基础上才能够建立Wi-Fi连接，而是能够直接基于Wi-Fi接口的MAC地址建立Wi-Fi连接。
随机数子字段，占用32个字节，其取值为根据PC的产品序列号(serial number，SN)进行哈希(hash)运算后获得的hash值。其中，SN号为PC身份识别码，为PC的唯一机器编码。
S702、手机确定该Wi-Fi接口的MAC地址对应的设备是支持Wi-Fi参数协商能力的邻设备。
在一些实施例中，路由器基于本地安全策略，将接入设备在注册过程中注册 的设备信息进行广播，同步给局域网内连接的各个设备。进而手机监听广播后，可以保存接入该路由器的设备列表信息，基于该设备列表信息能够发现局域网内的邻设备。从而接收到Wi-Fi接口的MAC地址后，能够发现邻设备中支持Wi-Fi参数协商能力的PC。可选的，Wi-Fi参数协商能力例如包括Wi-Fi热点参数协商能力。
在一些实施例中，手机在获得PC Wi-Fi接口的MAC地址后，需要确定PC是否为支持Wi-Fi热点参数协商能力的设备，具备Wi-Fi热点参数协商能力的PC设备，能够与手机与PC之间进行无线投屏和/或跨设备文件分享。其中，手机可以利用本地缓存的设备列表信息，查询该Wi-Fi接口的MAC地址对应的设备是否支持Wi-Fi热点参数协商能力。若在本地设备列表中未查询到该Wi-Fi接口的MAC地址对应的设备，则可以向路由器发送查询请求，由路由器进行查询，并接收路由器发送的查询结果。
示例性的，手机可以向路由器发送查询请求报文，用于向路由器查询指定设备标识，指定MAC地址，或指定能力的设备列表。
比如，该查询请求报文例如为“GET/cord？st＝WifiCfg”。其中，“st”字段用于指示过滤筛选条件，“WifiCfg”字段用于指示查询具有Wi-Fi热点参数协商能力的设备。具体的，若设备支持无线投屏和/或跨设备文件分享，则需要支持Wi-Fi热点参数协商能力，因此，利用该报文，可以查询支持投屏能力的设备。
相应的，路由器在接收到查询请求报文后，会向手机发送查询响应报文，该查询响应报文中携带查询结果。如下示出一种查询响应报文示例。
Figure PCTCN2021136692-appb-000011
Figure PCTCN2021136692-appb-000012
上述查询响应报文中，“sn”字段用于指示具有Wi-Fi热点参数协商能力的设备的SN号。例如为00E0FC018008。手机根据SN号可以确定对应的设备。进一步的，该SN号字段还可以利用MAC地址进行填充，MAC地址也可以用于指示唯一对应的设备。
需要说明的是，在上述步骤S701中，手机还可以获取PC的NFC参数信息中包含的蓝牙接口的MAC地址。那么，在步骤S702中，若手机自身以及路由器查询支持Wi-Fi热点参数协商能力的邻设备的过程均失败，即未能查询到相应的PC，则手机利用蓝牙接口的MAC地址，与PC建立蓝牙连接，再建立Wi-Fi P2P工作组。其中，基于蓝牙连接建立Wi-Fi P2P工作组可以参照图3-图5所示的方法，在此不再赘述。
S703、手机显示确认界面，检测确认操作，确认与PC建立连接。
在一些实施例中，手机在通过上述步骤S702查询到可投屏的PC后，需要再由用户确认该PC是否为目标投屏设备。若是，则执行下述投屏参数协商过程。若不是，则需要再次重复上述步骤S701和步骤S702，重新查找PC，或放弃投屏操作。
示例性的，如图9所示界面901，手机显示通知栏91，用于提示用户当前正在建立投屏连接，由用户确认是否允许在该PC上进行投屏。其中，当前可能存在多个PC，则可以利用PC的SN码，或者利用用户自定义的PC名称等方式提示用户当前待连接的目标PC为多个PC中的哪一个PC，便于用户区分，如界面901中提示用户“PC(XXX)”中XXX即表示提示方式对应的内容。检测到用户点击控件92的操作，确认用户允许利用目标PC进行投屏，则需要与目标PC间建立投屏连接，用于传输投屏数据。
S704a、手机向路由器发送参数协商请求，参数协商请求中携带PC标识以及第一射频参数。
其中，第一射频参数包括手机支持的射频频段和信道中当前能够应用的射频频段和信道。PC标识例如包括PC的MAC地址，或预定义的PC标识等，路由器根据PC标识确定发送参数协商请求的目标PC，后续手机利用目标PC进行无线投屏。可选的，手机作为投屏源设备，PC作为投屏目标设备。在参数协商请求中携带目标设备标识和/或源设备标识，用于识别对端设备。
在一些实施例中，手机确定与PC建立连接，则需要协商Wi-Fi P2P连接参数，以建立Wi-Fi P2P工作组，手机需要将自身支持且可用的射频参数发送至PC。但是，为了保证网络安全，路由器设置了二层隔离，不允许手机和PC之间直接通信，而是由路由器对手机和PC之间的信号进行转发，从而实现对接入路由器网络的设备的权限和流量进行审计。因此，手机将自身支持且可用的射频参数发送至路由器，由路由器基于参数协商请求中携带的目标PC标识，将接收到的射频参数转发至相应的目标PC。进而目标PC基于该射频参数选择确定需要应用的射频参数。
示例性的，请求报文如下所示：

在一些实施例中，PC在接收到手机发送的第一射频参数后，根据第一射频参数以及自身支持且当前可用的射频参数，选择最佳射频频段和信道，作为目标射频参数。比如，PC在自身和手机均支持且可用的射频频段和信道中选择预期信号质量最好的射频频段和信道。又比如，PC在自身和手机均支持且可用的射频频段和信道中选择时延最小的射频频段和信道。
在一些实施例中，PC在确定目标射频参数后，创建热点，将自身作为软接入点(soft AP)设备，配置射频接口的Wi-Fi P2P工作组的射频参数，以便后续手机能够接入该射频接口，传输投屏数据。进一步的，PC作为soft AP设备基于目标射频参数，按照预设周期发送信标(beacon)帧，使得手机可以发现该soft AP设备。
在一些实施例中，PC还可以配置热点的SSID，后续手机利用该SSID接入PC热点。可选的，PC可以单独配置生成热点的SSID，并将该SSID发送至手机。或者，预配置热点的SSID，将该SSID配置于PC和手机中，在PC需要配置热点的SSID时，直接获取预置的SSID进行配置。那么，PC则不必向手机发送SSID，手机根据预配置的SSID即可确定对应热点的SSID。
S706a、PC向路由器发送参数协商响应，参数协商响应中携带目标射频参数。
在一些实施例中，PC在确定目标射频参数后，沿接收参数协商请求的路径，将目标射频参数发送至路由器，由路由器转发至手机，实现PC与手机建立Wi-Fi P2P工作组。可选的，参数协商响应中还可以携带热点的SSID，功率值。
示例性的，如下示出一种参数协商响应报文。
HTTP/1.1 200 OK
[BODY]
其中，“200 OK”字段，用于表示对应请求已经被成功地处理在服务器上。即已经进行目标射频参数选择。“BODY”字段，用于承载报文的有效载荷，如目标射频参数。BODY字段都采用JSON报文格式，编码为UTF-8方式。BODY字段中包含PC选择创建热点的频段和对应信道信息，和/或SSID，和/或源设备标识和目标设备标识。其中，设备标识例如为设备SN。
S706b、路由器向手机转发参数协商响应。
在一些实施例中，路由器在接收到参数协商响应后，将参数协商响应转发至相应的发送参数协商请求的手机。可选的，在上述步骤S704a中，参数协商请求中还可以携带手机标识。相应的，PC发送的参数协商响应中携带该手机标识，那 么路由器在接收到参数协商响应后，能够根据手机标识，将该参数协商响应发送至目标手机。
由此，手机基于Hilink生态相关协议，新增用于传输Wi-Fi协商参数的协议接口。如在本申请实施例中，手机利用与路由器之间通过如图6所示方法建立的Hilink会话通道，传输第一射频参数，并接收PC确定的目标射频参数，实现与PC之间的射频参数协商。相对于图5所示的PC与手机基于链路层协议进行Wi-Fi参数协商，本申请实施例能够基于应用层协议(即Hilink生态相关协议)执行参数协商过程，不必受限于蓝牙连接。
S707、手机与PC创建Wi-Fi P2P socket连接，并开始传输数据。
在一些实施例中，手机接收到参数协商响应后，确定参数协商成功。按照协商确定的目标射频参数中指定的射频频段和信道，基于802.11协议发送探测请求(probe request)管理帧，用于搜索PC发送的beacon帧。在搜索到PC后，自动触发认证和关联流程，与PC创建Wi-Fi P2P socket连接，进而开始进行投屏数据的传输。其中，传输的投屏数据例如包括视频图像信息，键鼠信息等。手机与PC的Wi-Fi认证和关联流程可以参考现有技术，在此不再赘述。
在一些场景中，路由器在局域网内未设置二层隔离，手机和PC之间能够直接进行通信。那么，在手机和PC进行参数协商的过程中，则不需要利用路由器转发用于协商的参数。
示例性的，在手机和PC直接进行参数协商场景中，如图10所示，参数协商过程包括S704c-S706c。
S704c、手机向PC发送参数协商请求，参数协商请求中携带第一射频参数。
在一些实施例中，手机和PC支持特定的表述性状态传递(representational state transfer，REST)接口，手机和PC能够基于该REST接口直接进行通信。可选的，手机接收路由器广播的设备列表信息，在设备列表信息中获取PC的IP地址。或者，手机根据在上述步骤S701中获取的MAC地址查找地址解析协议(address resolution protocol，ARP)表，根据ARP表中MAC地址与IP地址的对应关系，确定PC的IP地址。之后，手机利用该IP地址，向PC发送参数协商请求。
其中，REST用于指示数据传输过程中客户端和服务端的数据交互规则。PC作为REST接口的服务端，手机作为REST接口的客户端。
可选的，参数协商请求报文基于UPnP协议或CoAP，以HTTP(s)GET或HTTP(s)POST的方式进行传输。其中，参数协商请求报文的格式可以参考上述步骤S704a所述的请求报文的格式，在此不再赘述。

可选的，步骤S705-步骤S706c的其余内容，可以参考上述图7所示的步骤S705-步骤S706b中的相关内容，在此不再赘述。
由此，本申请实施例提供的连接建立方法，基于NFC功能，手机能够直接在PC的NFC模块中获取其Wi-Fi接口的MAC地址，利用该Wi-Fi接口的MAC地址与PC建立Wi-Fi P2P工作组，进行数据传输。相对于现有技术中的连接方法，不必先进行蓝牙连接，再基于蓝牙连接建立Wi-Fi P2P工作组。避免出现由于蓝牙连接的性能及稳定性差造成的建链时延较大的问题，提高交互性能。
在一些场景中，手机也可以不通过NFC碰一碰发现PC，那么手机可以直接接收用户选择的PC，确定对应的Wi-Fi接口的MAC地址，建立Wi-Fi P2P工作组。
示例性的，图11为本申请实施例提供的又一种连接建立方法。如图11所示，该方法包括S1101-S1108。
S1101、PC接入路由器，并向路由器注册。
S1102、手机接入路由器，并向路由器注册。

可选的，步骤S1101-步骤S1102的其余内容，可以参考上述步骤S601-步骤S610中的相关内容，在此不再赘述。
S1103、手机显示待投屏界面，检测到用户搜索投屏设备的操作，搜索投屏设备。
S1104、手机向路由器发送投屏设备查询请求。
S1105、路由器向手机发送投屏设备查询结果。
S1106、手机显示投屏设备选择界面，检测到用户选择投屏设备的操作，确定投屏设备为PC。
在一些实施例中，在步骤S1103-步骤S1106中，手机在检测到用户的投屏操作后，开始查找能够用于投屏的邻设备。比如，向路由器发送查询请求。路由器接收到查询请求后，基于接入路由器的设备的注册信息，查询支持Wi-Fi热点参数协商能力设备，并将查询结果发送至手机。可选的，该查询结果中包含设备的Wi-Fi接口的MAC地址。手机接收到查询结果后，由用户确认是否利用查询到的设备进行投屏。若是，则基于用户选中的投屏设备的Wi-Fi接口的MAC地址，与该投屏设备进行Wi-Fi热点参数协商，进而建立Wi-Fi P2P工作组，开始进行投屏。又比如，手机监听路由器变更同步的邻居设备信息，获取设备列表信息。进而手机根据设备列表信息，直接查询支持Wi-Fi热点参数协商能力的投屏设备，以及对应的Wi-Fi接口的MAC地址。
示例性的，如图12中(a)所示界面1201，手机检测到用户点击控件121的操作，确定用户需要将当前显示的视频画面进行投屏。手机显示如图12中(b)所示界面1202，开始搜索可用于投屏的投屏设备，并显示提示内容122，用于提示用户当前手机正在搜索设备。之后，手机显示如图12中(c)所示界面1203，用于接收用户选中投屏设备的操作。例如，手机在界面1203上检测到用户点击设 备名称123的操作，确定投屏设备为PC。
S1107、手机与PC进行射频参数协商。
S1108、手机与PC创建Wi-Fi P2P socket连接，并开始传输数据。
