具体实施方式
下面结合说明书附图对本申请实施例做详细描述。
本申请实施例可以适用于局域网(local area networks，LAN)，特别是无线局域网(wireless local area networks，WLAN)，比如可以适用于采用电气电子工程师协会(institute of electrical and electronics engineers，IEEE)802.11系列协议中的任意一种协议的WLAN。其中，WLAN可以包括一个或多个基本服务集(basic service set，BSS)，基本服务集中的网络节点包括接入点(access point，AP)和站点(station，STA)。此外，IEEE 802.11ad在原有的BSS基础上，引入个人基本服务集(personal basic service set，PBSS)和个人基本服务集控制节点(PBSS control point，PCP)，个人基本服务集可以包含一个AP/PCP和多个关联于该AP/PCP的非(non)AP/PCP，本申请实施例中non AP/PCP可以称为STA，PCP可以理解为AP在PBSS里的角色的称呼。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例也可以适用于物联网(internet of things，IoT)网络或车联网(vehicle to X，V2X)网络等无线局域网中。当然，本申请实施例还可以适用于其它可能的通信系统，例如长期演进(long term evolution，LTE)通信系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、第五代(5th generation，5G)通信系统以及未来演进的通信系统等。
本申请中，AP可以为终端设备(如手机)进入有线(或无线)网络的接入点。AP相当于一个连接有线网络和无线网络的桥梁，主要作用是将各个无线网络客户端连接到一起，然后将无线网络接入以太网。比如，AP可以是带有无线保真(wireless-fidelity，Wi-Fi)芯片的终端设备(如手机)或者网络设备(如路由器)。本申请实施例中，AP可以为支持802.11be制式的设备，或者也可以为支持802.11ax、802.11ay、802.11ac、802.11n、802.11g、802.11b、802.11a以及802.11be下一代等802.11系列的多种WLAN制式的设备。
STA可以为无线通讯芯片、无线传感器或终端设备等。例如，STA可以为支持Wi-Fi通讯功能的终端设备、支持Wi-Fi通讯功能的IoT设备、支持Wi-Fi通讯功能的移动电话、支持Wi-Fi通讯功能的平板电脑、支持Wi-Fi通讯功能的机顶盒、支持Wi-Fi通讯功能的智能电视、支持Wi-Fi通讯功能的智能可穿戴设备、支持Wi-Fi通讯功能的车载通信设备和支持Wi-Fi通讯功能的计算机等。可选地，STA可以支持802.11be制式，或者也可以支持802.11ax、802.11ay、802.11ac、802.11n、802.11g、802.11b、802.11a、802.11be下一代等802.11系列的多种WLAN制式。
本申请中，智能设备或IoT设备可以包括但不限于智能灯具、智能插座、智能开关、智能摄像头、智能家电、智能机顶盒、智能窗帘、智能门等支持Wi-Fi通讯功能的设备。
下文以本申请实施例适用于WLAN为例。参见图1，示出了本申请实施例适用的一种WLAN的网络架构图，图1是以该WLAN包括1个AP和2个STA为例。其中，与AP关联的STA，能够接收该AP发送的无线帧，也能够向该AP发送无线帧。本申请实施例将以AP和STA之间的通信为例进行描述，可以理解的是，本申请实施例也可以适用于AP与AP之间的通信，例如各个AP之间可通过分布式系统(distributed system，DS)相互通信，也可以适用于STA与STA之间的通信。
其中，STA1可以为终端设备，STA2可以为IoT设备的等智能设备，本申请对此并不限定。
可以理解的是，图1中所示意的AP和STA的数量仅是举例，还可以更多或者更少。
对于IoT设备等设备，在第一次与AP连接之前，由于无法获得AP建立的网络的服务集标识(service set identifier，SSID)以及接入密码，因此需要进行配网。配网是指通信设备获取AP的网络信息(例如 SSID以及接入密码等)，并根据该网络信息连接AP的过程。
目前，对于IoT设备等不具备丰富人机交互界面的设备，可以通过手机等终端设备为这些设备完成配网，这种配网方式也可以称为软(soft)AP配网方式。在soft AP配网方式中，待配网的IoT设备通过软件在IoT设备上实现AP功能，使得IoT设备能够像AP一样工作，终端设备从而能够与该IoT设备建立连接。终端设备与IoT设备建立连接之后，可以将SSID以及该SSID对应的接入密码发送至IoT设备，其中，SSID以及接入密码可以采用加密方式传输。IoT设备可以根据获取到SSID以及接入密码接入网络，从而完成配网。
在soft AP配网方式中，需要用户在终端设备中输入接入密码等操作，对于用户来说，流程复杂且耗时较长。为此，本申请提供一种配网方式，可以减少用户在终端设备中的操作，方便快捷的完成设备的配网过程，提高配网效率，特别适用于同时为多个设备进行配网的批量配网场景。
下面结合具体实施例对本申请实施例提供的方法进行详细描述。在具体实施例中，将以本申请实施例所提供的方法应用于图1所示的网络架构为例。本申请中以网络设备、第一终端设备以及第二终端设备之间的交互为例进行描述。网络设备可以为AP，也可以替换为能够支持AP实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片或芯片系统。第一终端设备以及第二终端设备可以为STA，也可以替换为能够支持STA实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片或芯片系统。其中，第二终端设备可以为待配网的设备，例如可以为待配网的IoT设备。
在描述本申请提供的方法之前，本申请提供一种设备发现方法，可以使得第一终端设备获取到第二终端设备(即待配网的设备)的相关信息，下面将详细描述。
图2为本申请实施例提供的一种设备发现方法流程示意图。在该流程之前，第一终端设备已经与网络设备建立连接，第二终端设备没有与网络设备建立连接，该流程可以包括：
S201：第一终端设备向网络设备发送第一消息，第一消息用于指示网络设备启动配网模式。
举例来说，第一终端设备中可以安装与网络设备相关的应用程序(application，APP)，用户可以在该APP中对网络设备执行相关操作。例如，用户可以在第一终端设备的APP中触发将网络设备配置为配网模式的指令，此时第一终端设备可以根据用户的指令网络设备发送第一消息。
S202：网络设备建立第一网络。
一种实现方式中，第一网络可以称为预连接网络或专门用于配网的网络，即其它设备(例如第二终端设备)可以接入第一网络，可以访问第一网络内的网络设备，但不具有通过该网络设备访问外网的权限。这样，第二终端设备等智能设备通过接入第一网络，实现建立了与网络设备之间的通信通道。
一种实现方式中，第一网络的SSID可以为随机的SSID，也可以为预设的SSID。示例性的，第一网络的SSID可以标识其为预连接网络或专门用于配网的网络，以表明该第一网络与其它网络相区别。
一种实现方式中，第一网络为无接入密码的网络或第一网络为开放性网络，这样所有智能设备都可以快速接入第一网络。另一种实现方式中，第一网络可以为有接入密码的网络，该接入网密码可以是预先配置的，第二设备等智能设备可以预先获取到第一网络的接入密码。
本申请中，对第一网络所在的信道并不限定，可以为网络设备在建立第一网络之前，工作的网络的信道；网络设备也可以根据实际情况，为第一网络选择合适的工作信道，本申请对此并不限定。
S203：网络设备发送探测请求(probe request)消息。
其中，探测请求消息可以用于指示待配网的设备上报设备信息。
一种实现方式中，探测请求消息中包括第二指示信息，该第二指示信息用于指示网络设备支持的配网方式。举例来说，探测请求消息中包括专属IoT配网方式的信息元素(information element，IE)，第二指示信息位于该IE中。例如，专属IoT配网方式的IE可以如表1所示。表1所示的IE包括IE标识(identification，ID)字段、长度(length，len)字段、组织唯一标志符(organizationally unique identifier，OUI)字段、类型(type)字段以及扩展信息字段。其中第二指示信息可以位于扩展信息字段。
表1
表1中，IE ID字段、OUI字段以及type字段对应的内容，只是示例，不代表对上述各个字段的限制。len字段用于指示该IE的长度，具体取值根据实际情况确定。
以上只是示例，专属IoT配网方式的IE还可能存在其他实现方式，本申请对此并不限定。
本申请中，网络设备可以支持多种配网方式，例如可以支持传统的soft AP配网方式，还可以支持本申请提供的配网方式。为了描述方便，将本申请提供的配网方式称为批量配网方式，也可以采用其他名称对本申请提供的配网方式进行命名，本申请对此并不限定。
由于第二终端设备还没有与网络设备建立连接，此时的探测请求消息可以是网络设备广播的消息。网络设备可以在多个信道发送探测请求消息，每个信道可以发送多次探测请求消息，本申请对此并不限定。
假设第二终端设备为待配网的设备，第二终端设备接收到探测请求消息，则可以执行以下步骤。
S204：第二终端设备向网络设备发送探测响应(probe response)消息。
其中，探测响应消息包括第二终端设备的设备信息。其中，设备信息可以包括以下至少一项信息：第二终端设备的设备标识；第二终端设备的设备类型；第三指示信息。
其中，第三指示信息用于指示第二终端设备支持的配网方式。例如，第三指示信息指示第二终端设备支持soft AP配网方式以及本申请提供的批量配网方式等。
举例来说，探测响应消息中包括专属IoT配网方式的IE，第三指示信息位于该IE中。例如，专属IoT配网方式的IE可以如表2所示，其中设备信息可以位于扩展信息字段。
表2
同样的，表2中，IE ID字段、OUI字段以及type字段对应的内容，只是示例，不代表对上述各个字段的限制。len字段用于指示该IE的长度，具体取值根据实际情况确定。
S205：网络设备向第一终端设备发送第二终端设备的设备信息。
第一终端设备接收到第二终端设备的设备信息之后，可以显示第二终端设备对应的设备图标等信息。举例来说，如图3所示，第一终端设备从网络设备获取到多个待配网的第二终端设备，例如包括智能电视、智能摄像头、智能音箱、智能手环、智能扫地机、智能灯泡以及智能体脂称。第一终端设备可以在界面显示每个待配网设备的图标以及对应的名称等信息，其中不同设备类型可以对应不同的图标，从而可以方便用户识别第二终端设备的设备类型。
一种可能的实现方式中，如果第二终端设备支持本申请提供的批量配网方式，第一终端设备还可以在界面中对第二终端设备的图标进行标记，使得用户可以通过每个设备的图标确定该设备是否支持批量配网方式。举例来说，如图4所示，假设智能电视、智能音箱、智能手环以及智能体脂称支持批量配网方式，那么第一终端设备可以在上述设备的图标旁边显示一个五角星，而不支持批量配网方式的图标不显示五角星，那么用户就可以根据五角星确定哪些设备支持批量配网方式。
以上只是示例，第一终端设备还可以通过其他方式对支持批量配网方式的设备进行标记，在此不再赘述。
一种可能的实现方式中，如果用户认为有些第二终端设备不是属于自己的，那么还可以在第一终端设备中进行删除操作，从而删除那些不属于自己的设备。例如，结合前面的图3，如图5所示，假设智能电视不属于用户，用户可以选定智能电视，第一终端设备中出现“删除”的选项，当用户点击“删除”时，可以将智能电视相关的信息删除。
以上只是示例，还可能存在其他方式发现待配网的设备。例如，用户可以手动操作获取待配网设备的设备信息。例如，如图6所示，用户可以使用第一终端设备扫描第二终端设备的机身、包装盒或使用手册中的二维码或二维条形码等，从而可以发现待配网的设备。
本申请中，用户可以通过第一终端设备向网络设备指示将哪些设备接入网络，即对哪些设备进行配网，下面将详细描述。
图7为本申请实施例提供的一种网络连接方法所对应的流程示意图，该流程可以包括：
S701：第一终端设备向网络设备发送第一指示信息；相应的，网络设备接收来自第一终端设备的第一指示信息，第一指示信息用于指示将第二终端设备接入网络。
举例来说，用户可以在第一终端设备的用户界面中选择第二终端设备，第一终端设备从而可以根据用户的操作发送第一指示信息。
本申请中，用户可以同时指示将多个第二终端设备接入网络，即第一指示信息可以指示将多个第二 终端设备接入网络，这里只是以一个第二终端设备为例进行描述。
举例来说，如图8所示，用户在第一终端设备的用户界面中可以选择多个第二终端设备，例如选择智能摄像头、智能音箱、智能扫地机、智能灯泡以及智能体脂称，图中被标记“√”的设备为用户选择的设备。当用户选中这些设备后，点击用户界面中的“确定”，就可以实现触发第一终端设备发送第一指示信息。此时的第一指示信息用于指示将智能摄像头、智能音箱、智能扫地机、智能灯泡以及智能体脂称接入网络。
S702：网络设备根据第一指示信息发送第一探测请求消息；相应的，第二终端设备接收来自网络设备的第一探测请求消息。
其中，第一探测请求消息用于指示第二终端设备接入网络设备的第一网络。由于第二终端设备还没有与网络设备建立连接，此时的第一探测请求消息可以是网络设备广播的消息。
本申请中，第一探测请求消息包括以下至少一项信息：
第二终端设备的设备标识；第一网络的信道的信道标识；有效时间信息，有效时间信息用于指示第一探测请求消息有效的时间或者配网启动剩余时间。
其中，如果有多个第二终端设备需要接入网络，第一探测请求消息可以包括多个第二终端设备的设备标识。信道标识可以指示第一网络所在的信道，使得第二终端设备能够快速接入第一网络。有效时间信息可以指示网络设备在哪个时间段内将第二终端设备接入网络。
举例来说，第一探测请求消息中包括IoT配网IE，上述信息位于该IE中。例如，IoT配网IE可以如表3所示，其中第二终端设备的标识等信息可以位于扩展信息字段。
表3
表3中，IE ID字段、OUI字段以及type字段对应的内容，只是示例，不代表对上述各个字段的限制。len字段用于指示该IE的长度，具体取值根据实际情况确定。
第一探测请求消息还可以包括第一网络的SSID等信息，第一探测请求消息具体携带的内容，本申请并不限定。
S703：第二终端设备向网络设备发送第一探测响应消息；相应的，网络设备接收来自第二终端设备的第一探测响应消息。
S703为可选步骤，第二终端设备也可以不反馈第一探测响应消息。
第一探测响应消息可以包括第二终端设备的标识等信息。第一探测响应消息也可以包括IoT配网IE，具体可以参考前面的描述，在此不再赘述。
S704：第二终端设备接入第一网络。
第二终端设备接收到第一探测请求消息之后，如果确定第一探测请求消息包括该第二终端设备的标识，则可以将工作信道切换到第一网络所处的信道，并接入第一网络。第二终端设备接入第一网络的具体过程，本申请对此并不限定，在此不再赘述。
一种实现方式中，第二终端设备接入第一网络时，可以与网络设备建立连接。例如第二终端设备可以与网络设备建立传输控制协议(transmission control protocol，TCP)连接。第二终端设备与网络设备之间，可以通过TCP连接进行互联网协议(internet protocol，IP)层非对称秘钥协商，从而获得IP层非对称秘钥。第二终端设备与网络设备之间的消息可以通过该IP层非对称秘钥进行加密。其中，该IP层非对称秘钥协商的具体过程，本申请对此并不限定。
S705：网络设备在第一网络中向第二终端设备发送第二网络的网络标识和第二网络的接入密码；相应的，在第一网络中接收来自网络设备的网络标识和接入密码。
其中，第二网络的网络标识和第二网络的接入密码用于第二终端设备接入第二网络。
一种实现方式中，第二网络的网络标识和/或第二网络的接入密码通过IP层加密传输，例如通过IP层非对称秘钥加密后传输。通过对接入密码等信息加密，可以保证通信的安全性，提高网络安全。
一种实现方式中，接入密码可以是为第二终端设备生成的随机密码。在该情况下，对于同一个第二 网络，不同终端设备可以对应不同的接入密码，从而提高网络安全。
S706：第二终端设备根据第二网络的网络标识和第二网络的接入密码接入第二网络。
其中，第二终端设备在接入第二网络之前，断开与第一网络的连接。
一种实现方式中，第二网络为网络设备建立的无线局域网。网络设备可以先释放第一网络，再建立第二网络。第二网络也可以为其它网络设备建立的无线局域网，本申请对此并不限定。
本申请中，第二终端设备接入网络设备的关联入网流程包括三个阶段：认证阶段，关联阶段，以及基于局域网的扩展认证协议(extensible authentication protocol over LAN，EAPOL)四步握手阶段。上述各个阶段的具体过程，本申请并不限定，在此不再赘述。
一种实现方式中，第二终端设备接入第二网络之后，可以通过网络设备与其它设备进行通信，例如与第一终端设备进行通信。第二终端设备接入第二网络之后，可以通过网络设备与第二网络之内的设备进行通信，也可以与第二网络之外的设备进行通信，本申请对此并不限定。
一种实现方式中，第二终端设备接入第二网络之后，可以向用户发送提示信息，从而使得用户根据该提示信息确定第二终端设备成功接入网络。例如第二终端设备可以通过扬声器发出“成功接入网络”的音频信息，用户从而确定第二终端设备成功接入网络。
通过上述方法，在为第二终端设备配网时，第一终端设备只需要向网络设备发送第一指示信息即可，可以减少用户在第一终端设备中的操作，方便快捷的完成第二终端设备的配网过程，提高配网效率，特别适用于同时为多个设备进行配网的批量配网场景。
