具体实施方式
图1为本申请适用的一种系统架构的示意图。图1中以多个音箱构建音箱系统为例进行说明。参照图1，该系统架构中包括多个音箱，分别为左置音箱11、右置音箱12、左环绕音箱13、右环绕音箱14，以及低音炮音箱15。其中，左置音箱11、右置音箱12、左环绕音箱13、右环绕音箱14，以及低音炮音箱15可以通过无线连接组成音箱系统。应理解，图1中的音箱的类型以及个数为示例说明，并不构成对本申请实施例适用的系统架构的限定。
在音箱系统中，各音箱可以根据自身性能，输出不同声道的音频，使得音箱系统输出的音频可以达到立体声效果。示例性的，如左置音箱11可以输出左声道音频，右置音箱12可以输出右声道音频，左环绕音箱13可以输出左环绕音频，右环绕音箱14可以输出右环绕音频，以及低音炮音箱15可以输出低音声道音频，使得用户可以听到具有立体声效果的音频。
其中，多个音箱组成音箱系统的关键一步是：多个音箱通过无线连接组成一个网络。在一种实施例中，用户可以在终端上依次对多个音箱进行配网，让各音箱接入同一局域网，即多个音箱通过无线连接组成一个网络，多个音箱组成了音箱系统。如用户可以在终端的应用程序(application，APP)中先将第一个音箱配网，然后再添加第二个音箱，且将第二个音箱配网，直至完成多个音箱的配网。应理解，各音箱接入同一局域网可以理解为：将各音箱接入同一接入点(access point，AP)，如AP可以为路由器。
但该种方式需要用户依次对多个音箱进行配网，操作繁琐、配网时间长，效率低，且该多个音箱需要依赖同一AP接入同一局域网。
在一种实施例中，在音箱的生产制造过程中，可以预设每个音箱的角色，且在各音箱中预置密钥。其中，预设各音箱的角色如将左置音箱11设置为主音箱，将其他音箱设置为从音箱。在多音箱进行无线连接时，基于预设的角色，从音箱可以根据密钥，采用无线扬声器和音频(wireless speaker and audio，WISA)等连接方式，接入主音箱，实现多个音箱的无线连接。
该种实施例中，因为已预设每个音箱的角色以及密钥，因此该多个音箱需要成套售卖，维护成本高。
因此亟需一种适用范围广，且能够快速、安全的组网方法，实现多个音箱的无线连接。本申请实施例中提供一种组网方法，不依赖AP(如路由器)，无需预先设置各音箱的角色和密钥，而是由音箱之间协商建立无线连接，组网效率高，且任一个音箱出现故障即可替换，适用范围广、维护成本低。应理解，本申请实施例中的多设备组网表征：多设备进行无线连接组成一个网络。
图2为本申请实施例中音箱的一种结构示意图。应理解，图1所示的每个音箱的结构可以相同，均可以参照图2的描述。参照图2，音箱20可以包括：按键21、指示灯22、麦克风23、扬声器24、蓝牙芯片25、无线保真(wireless fidelity，Wi-Fi)芯片26、处理器27，以及天线28。
其中，音箱20可以通过蓝牙芯片25和天线28与其他设备建立蓝牙信道，以实现蓝牙通信。音箱20可以通过Wi-Fi芯片26和天线28与其他设备建立Wi-Fi信道，以实现Wi-Fi通信。在一种实施例中，蓝牙芯片25和Wi-Fi芯片26可以共用天线28，或者蓝牙芯片25和Wi-Fi芯片26分别对应单独的天线28。应理解，图2中以蓝牙芯片25和Wi-Fi芯片26共用天线28为例进行说明。
处理器27，可以用于执行下述实施例中S301-S314，完成多音箱组网。
在一种实施例中，处理器27中可以包括：超声检测模块、用户交互模块、设备发现模块、组网管理 模块、认证鉴权模块，以及连接管理模块。其中，处理器27中的各模块的名称为示例说明，其中部分模块(或全部模块)可以集成为一体设置。
用户交互模块，用于管理按键21、指示灯22、麦克风23，以及扬声器24。示例性的，用户交互模块可以检测用户对按键21的操作，以及通过麦克风23采集声音。另，用户交互模块可以控制指示灯23闪烁、显示不同颜色等，用户交互模块还可以控制扬声器24播放音频。
设备发现模块，用于发现其他音箱，发现其他音箱是与其他音箱进行组网的基础。在一种实施例中，设备发现模块可以采用蓝牙广播或者Wi-Fi广播的方式，发现其他音箱，以与其他音箱进行组网。示例性的，设备发现模块可以发送Wi-Fi探测帧(Wi-Fi probe)，以发现其他音箱。在一种实施例中，设备发现模块可以执行下述实施例中的S301-S308。
在一种实施例中，音箱20上还可以设置超宽带(ultra wide band，UWB)标签，设备发现模块可以采用UWB技术，发现其他音箱。
在一种实施例中，设备发现模块还可以采用WLAN感知概览(Wi-Fi aware)技术发现其他音箱，本申请实施例中对设备发现模块发现其他音箱采用的方法不做限制，下述实施例中以采用蓝牙广播的方式发现设备为例进行说明。
超声检测模块，用于发射超声波，以及检测其他音箱发射的超声波。
在一种实施例中，设备发现模块，还用于根据发射的超声波检测其他音箱是否与音箱处于同一房间(同室)，进而与处于同一房间的音箱进行组网。
认证鉴权模块，用于对其他音箱进行认证、鉴权。在一种实施例中，认证鉴权模块，可以执行下述实施例中的S309-S310。
在一种实施例中，音箱发现其他音箱之后，可以通过通信网络进行互联，以实现无线信号的交互。该通信网络可以但不限于为：Wi-Fi热点网络、Wi-Fi点对点(peer-to-peer，P2P)网络、WISA网络等。Wi-Fi点对点连接还可以称为Wi-Fi直连(Wi-Fi direct)。
下述实施例以音箱之间通过Wi-Fi点对点的连接方式进行连接为例进行说明。在该种实施例中，连接管理模块，用于管理Wi-Fi P2P层，如包括群组拥有者(group owner，GO)的启动和停止等。连接管理模块，还用于建立用于认证鉴权模块进行认证鉴权的物理通道、后续业务通道建立以及业务连接的管理。在一种实施例中，连接管理模块可以执行下述实施例中的S311-S314。
组网管理模块，可以理解为中心管理模块，用于对超声检测模块、用户交互模块、设备发现模块、认证鉴权模块，以及连接管理模块进行管理。示例性的，音箱发现其他音箱后，组网管理模块可以调用超声检测模块完成同室检测，筛选出处于同一房间的音箱。当筛选出的音箱满足组网要求时，可以触发用户交互模块提醒用户，让用户确认主音箱。用户确认主音箱后，组网管理模块根据用户确认的主设备，调用认证鉴权模块完成音箱的认证和鉴权。在认证和鉴权通过后，组网管理模块调用连接管理模块，完成各音箱的无线网络连接，即完成音箱组网。
在一种实施例中，音箱20还可以包括显示屏。显示屏，用于显示音箱的人机交互界面，图2中未示出显示屏。
可以理解的是，图2所示的结构并不构成对音箱的具体限定。在本申请另一些实施例中，音箱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。
应理解，本申请实施例提供的组网方法，不仅适用于多个音箱组网的场景中，还可以适用于其他设备进行组网的场景中。示例性的，本申请实施例提供的组网方法可以适用于家庭环境中智能家电的组网，还可以适用于工厂环境中工业无线终端的组网，本申请实施例对组网方法适用的场景不作限制。
下述实施例中以多个电子设备进行组网为例进行说明，该多个电子设备如可以包括：第一设备、第二设备，以及第三设备等，下述以第一设备、第二设备，以及第三设备的组网过程对本申请实施例提供的组网方法进行说明。
本申请实施例中的电子设备可以称为用户设备(user equipment，UE)、终端(terminal)等，例如，电子设备可以为手机、平板电脑(portable android device，PAD)、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备、车载设备或可穿戴设备，虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线 终端、智慧家庭(smart home)中的终端等，本申请实施例中对电子设备的形态不做具体限定。
下面结合具体的实施例对本申请实施例提供的组网方法进行说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本申请实施例提供的组网方法的一种实施例的流程示意图。参照图3，本申请实施例提供的组网方法可以包括：
S301，第一设备发送第一蓝牙广播。
在多个设备进行组网时，用户可以开启每个设备，且打开每个设备的蓝牙功能，以及无线局域网(wireless local area network，WLAN)功能。每个设备均可以执行步骤S301-S305，这里以第一设备为例说明每个设备执行的步骤。
第一设备打开蓝牙功能后，可以进行蓝牙扫描(如蓝牙低功耗(bluetooth low energy，BLE)扫描)，且监听来自其他设备的第一蓝牙广播。第一设备可以在询问扫描信道(inquiry scan channel)发送第一蓝牙广播。在一种实施例中，当第一设备发送Wi-Fi广播发现设备时，第一设备可以发送第一Wi-Fi广播。其中，第一广播包括：第一蓝牙广播或第一Wi-Fi广播，本申请实施例中以第一广播为第一蓝牙广播为例进行说明。
第一蓝牙广播用于发现第一设备周围的其他设备。示例性的，第一设备周围的其他设备在接收到该第一蓝牙广播时，可以响应该第一蓝牙广播。第一设备接收到其他设备的响应信号，可以确定第一设备的周围存在其他设备，即发现其他设备。
同理的，第一设备还可以在询问扫描信道监听来自其他设备的第一蓝牙广播，以响应于来自其他设备的第一蓝牙广播。
在一种实施例中，第一蓝牙广播中可以包括：第一设备的标识和第一设备的设备类型。第一设备的标识可以为第一设备的名称、型号等。如当第一设备为音箱时，第一设备的设备类型可以指示第一设备具体是那种类型的音箱，如低音炮音箱、左环绕音箱、左置音箱等。在一种实施例中，第一蓝牙广播可以为BLE广播、或传统蓝牙BR广播。
S302，第一设备发射超声波。
应理解，S302和S301可以同时执行，二者没有先后顺序的区分。
第一设备发射超声波的目的在于：筛选出与第一设备处于同室的设备。因为超声波在空气中传输时遇到障碍物会发生反射，因此超声波不能穿越墙体，与第一设备处于同室的设备可以接收到第一设备发射的超声波，但与第一设备未处于同室的设备不能接收到第一设备发射的超声波。
在一种实施例中，每个设备发射的超声波的频率可以不同，以便于接收到超声波的设备可以区分发射超声波的设备。示例性的，第一设备可以发射第一频率的超声波。
S303，第二设备向第一设备发送响应信号。
第二设备打开蓝牙功能后，可以进行蓝牙扫描，且监听来自其他设备的第一蓝牙广播。
在一种实施例中，第一蓝牙广播中还可以包括：第一设备发射的超声波的频率的标识，如该标识可以为第一频率。在该实施例中，若第二设备与第一设备处于同室，则第二设备可以接收到第一设备发射的超声波，且可以获取该超声波的频率。当第二设备监听到第一蓝牙广播，且接收到第一频率的超声波时，第二设备可以向第一设备发送响应信号。响应信号表征第二设备接收到来自第一设备的第一广播以及第一频率的超声波。该种实施例中，响应信号中可以包括：第二设备的标识和第二设备的设备类型。
其中，第二设备的标识可以为第二设备的名称、型号等。第二设备的设备类型如可以为：音箱、手机、手表等。示例性的，当第二设备的设备类型为音箱时，第二设备的设备类型还用于指示具体的音箱类别，如音箱的类型可以为左置音箱、右置音箱等。也就是说，当第二设备为其他类型的设备时，第二设备的设备类型也用于指示该设备的具体的类型。
在一种实施例中，第一蓝牙广播中可以不包括：第一设备发射的超声波的频率的标识，当第二设备监听到第一蓝牙广播，且接收到第一频率的超声波时，可以向第一设备发送响应信号，在该实施例中，响应信号中可以包括：第二设备的标识、第二设备的设备类型，以及用于指示第二设备接收到第一频率的超声波的标识。在一种实施例中，用于指示第二设备接收到第一频率的超声波的标识可以为：第一频率的标识，如第一频率。
在一种实施例中，第二设备在接收到第一蓝牙广播和第一频率的超声波时，可以分别向第一设备发送一个信号(例如，第一子信号和第二子信号)，以表征第二设备分别接收到第一蓝牙广播、第一频率的超声波。其中，响应信号可以包括第一子信号和第二子信号。在该种实施例中，第一蓝牙广播中可以包括第一频率的标识，或者不包括第一频率的标识。
在该种实施例中，当第二设备监听到第一蓝牙广播时，可以向第一设备发送第一子信号，第一子信号表征第二设备接收到第一蓝牙广播。该第一子信号中包括：第二设备的标识和第二设备的设备类型。第一设备响应于接收到来自第二设备的第一子信号，可以发射第一频率的超声波。若第二设备接收到第一频率的超声波，则可以向第一设备发送第二子信号，第二子信号用于表征第二设备接收到第一频率的超声波。
其中，当第一蓝牙广播中包括第一频率的标识时，第二子信号中可以包括第二设备的标识和第二设备的设备类型。当第一蓝牙广播中未包括第一频率的标识时，第二子信号中可以包括：第二设备的标识、第二设备的设备类型，以及用于指示第二设备接收到第一频率的超声波的标识。
在一种实施例中，若第二设备未与第一设备处于同室，则第二设备不能接收到第一设备发射的第一频率的超声波。在该实施例中，响应信号中可以包括：第二设备的标识和第二设备的设备类型。
在一种实施例中，第一设备还可以采用其他测距方式，测量第二设备与第一设备的距离，第一设备可以根据第二设备与第一设备的距离，检测第一设备和第二设备是否处于同室。其中，当第二设备与第一设备的距离小于或等于预设距离时，第一设备可以确定第二设备与第一设备同室。当第二设备与第一设备的距离大于预设距离时，第一设备可以确定第二设备未与第一设备同室。其中，测距方式可以包括但不限于：红外测距、蓝牙测距等方式。
下述实施例中以第二设备与第一设备处于同室为例进行说明。
应理解，图3中也示出了第一设备和第三设备之间的交互流程，第一设备和第三设备之间的交互流程可以参照第一设备和第二设备之间的交互流程。图3中以第三设备与第一设备处于同室为例进行说明。
S304，第一设备根据来自各设备的响应信号，确定待组网的设备。
第一设备发送第一蓝牙广播后，第一设备周围的其他打开蓝牙功能的设备均可以响应该第一蓝牙广播，因此第一设备可以接收到来自多个设备的响应信号。示例性的，如该多个设备可以包括第二设备、第三设备，以及第四设备，下述以第四设备与第一设备未处于同室为例进行说明。
第一设备根据来自各设备的响应信号，确定待组网的设备。在一种实施例中，第一设备可以将发送了响应信号、且与第一设备处于同室的设备，作为待组网的设备。
在一种实施例中，因为“既接收到来自第一设备的第一广播信号，且接收到第一频率的超声波”的设备可以向第一设备发送响应信号，因此第一设备可以确定发送响应信号的设备与第一设备处于同室，因此可以将发送响应信号的设备，作为待组网的设备。
在一种实施例中，因为检测到第一频率的超声波的设备，可以在响应信号中携带用于指示第二设备接收到第一频率的超声波的标识，在该种实施例中，第一设备还可以根据接收到的响应信号，确定待组网的设备。
示例性的，第一设备可以接收到来自第二设备、第三设备，以及第四设备的响应信号，因此可以确定第二设备、第三设备，以及第四设备均可以监听到第一广播信号。另，第一设备还可以检测来自第二设备的响应信号、第三设备的响应信号，以及第四设备的响应信号中是否包括“用于指示检测到第一频率的超声波的标识”，判断第二设备、第三设备，以及第四设备是否与第一设备处于同室。
示例性的，来自第二设备的响应信号和来自第三设备的响应信号中均包括“第一频率”，但第四设备的响应信号中未包括“第一频率”，第一设备可以确定第二设备和第三设备与第一设备处于同室，第四设备未与第一设备处于同室。如此，第一设备可以将第一设备、第二设备，以及第三设备作为待组网的设备。
本申请实施例中，第一设备将发送了响应信号、且与第一设备处于同室的设备，作为待组网的设备，可以避免第一设备与其他家庭或其他环境中的设备进行无线连接，可以避免误连接，提高组网准确性。
下述以第一设备、第二设备，以及第三设备作为待组网的设备为例进行说明。
S305，第一设备、第二设备，以及第三设备协商，确定出候选主设备。
第一设备、第二设备，以及第三设备协商，确定候选主设备的目的在于：确定第一设备、第二设备， 以及第三设备的角色，便于第一设备、第二设备以及第三设备根据自己的角色进行无线连接。角色可以包括主设备和从设备。主设备包含于待组网设备中，待组网设备中除了主设备之外的设备可以称为从设备。主设备，用于与从设备建立通信信道，以支持业务数据传输。在一种实施例中，候选主设备可以为待组网的设备中处理能力强的设备。
第一设备确定待组网的设备后，可以根据第一设备、第二设备，以及第三设备的设备类型，确定第一候选主设备，第一候选主设备可以为至少一个。示例性的，以第一设备为左置音箱、第二设备为右置音箱，以及第三设备为低音炮音箱为例进行说明，因为左置音箱和右置音箱的处理能力强，第一设备可以将左置音箱(第一设备)和右置音箱(第二设备)确定为第一候选主设备。
在一种实施例中，在第一设备确定第一候选主设备后，可以向第二设备、第三设备同步第一候选主设备的标识，如第一候选主设备的标识包括：左置音箱的标识，以及右置音箱的标识。同理的，第一设备也可以接收到第二设备确定的第二候选主设备的标识，以及第三设备确定的第三候选主设备的标识。也就是说，第一设备可以接收到其他设备确定的候选主设备的标识。
第一设备可以根据第一候选主设备、第二候选主设备，以及第三候选主设备，确定出候选主设备。
示例性的，第一设备可以将第一候选主设备、第二候选主设备，以及第三候选主设备中均包括的设备作为候选主设备。或者，第一设备可以将第一候选主设备、第二候选主设备，以及第三候选主设备中，出现次数最多的前N个设备作为候选主设备。N为大于或等于1的整数。
示例性的，如第一设备、第二设备，以及第三设备还可以采用相同的确定规则，确定候选主设备，因此第一设备、第二设备，以及第三设备确定出的候选主设备可以相同，如第一候选主设备、第二候选主设备，以及第三候选主设备相同，第一设备可以将第一候选主设备作为候选主设备。
下面以候选主设备包括第一设备和第二设备为例进行说明。
S306，候选主设备输出提示信息，提示信息用于提示用户选择主设备。
在一种实施例中，候选主设备输出的提示信息可以称为第一提示信息。
S305中讲述了第一设备可以确定出候选主设备，同理的，第二设备，以及第三设备也可以确定出候选主设备，因为采用相同的确定规则，第一设备、第二设备以及第三设备确定出的候选主设备相同。因为每个设备均可以确定候选主设备，因此被确定为候选主设备的设备可以输出提示信息，以表征自己是候选主设备。
在一种实施例中，在第一设备、第二设备以及第三设备确定出的候选主设备后，还可以相互同步自己确定的候选主设备，在候选主设备一致时，候选主设备可以输出提示信息。
图3中以候选主设备包括第一设备和第二设备为例说明，如第一设备、第二设备均可以确定候选主设备为第一设备和第二设备，则第一设备和第二设备均可以输出提示信息。其中，提示信息用于提示用户选择主设备。
在一种实施例中，以第一设备为例，第一设备可以采用语音方式输出提示信息，如第一设备可以播放“按压音箱上的按键，确定组网的主设备”。或者，为了便于用户更清楚的看到哪些设备输出了提示信息，第一设备还可以控制第一设备上的指示灯闪烁或显示不同颜色，以便用户快速确定候选主设备，以在候选主设备中选择主设备。
在一种实施例中，第一设备包括显示屏时，第一设备还可以在显示屏上显示提示信息。本申请实施例对候选主设备输出提示信息的方式不做限制。
在一种实施例中，第一设备、第二设备，以及第三设备可以协商确定出主设备，无需用户确认。
S307，响应于用户确认主设备的操作，主设备发送第二蓝牙广播，第二蓝牙广播中包括GO名称和Wi-Fi P2P信道的标识。
在一种实施例中，第一设备也可以通过发送Wi-Fi广播的方式广播GO名称和Wi-Fi P2P，在该种实施例中，响应于用户确认主设备的操作，主设备可以发送第二Wi-Fi广播。其中，第二蓝牙广播、第二Wi-Fi广播可以称为第二广播，本申请实施例中以第二广播为第二蓝牙广播为例进行说明。
图3中以用户确认第一设备为主设备为例进行说明。示例性的，用户可以在第一设备上按压按键，确认第一设备为主设备。
第一设备响应于用户确认主设备的操作，如第一设备检测到用户按压第一设备上的按键的操作，第一设备可以发送第二蓝牙广播。第二蓝牙广播用于与从设备建立Wi-Fi P2P连接。在一种实施例中，第 二蓝牙广播中可以包括：GO名称，以及Wi-Fi P2P信道的标识。GO为主设备，即第一设备，GO名称可以称为第一设备的标识。
其中，GO名称可以为：服务集标识(service set identifier，SSID)，或者主设备(第一设备)的媒体存取控制地址(media access control address，MAC)。待组网的设备中除了GO之外的第二设备、第三设备可以称为群组客户端(group client，GC)。Wi-Fi P2P信道的标识可以为：信道号，或信道所处的频段等。
S308，第二设备在Wi-Fi P2P信道与第一设备建立连接。
同理的，第三设备也可以在Wi-Fi P2P信道与第一设备建立连接。
其中，第二设备在询问扫描信道监听蓝牙广播，可以监听到第二蓝牙广播，进而可以得到GO名称和Wi-Fi P2P信道的标识。第二设备可以根据GO名称，在W-iFi P2P信道上与第一设备建立连接。
在一种实施例中，第二设备响应于监听到第二蓝牙广播，可以在Wi-Fi P2P信道中向第一设备反馈连接响应消息，表征第二设备在Wi-Fi P2P信道上与第一设备建立临时连接。应理解，Wi-Fi P2P信道可以简称为P2P信道。在一种实施例中，第二设备可以在Wi-Fi P2P信道上与第一设备建立连接的过程可以参照Wi-Fi P2P协议中的相关描述。
S309，第一设备对第二设备认证鉴权。
第一设备对第二设备认证鉴权时，可以并行对第三设备认证鉴权，进而提高认证鉴权的效率。
以第一设备对第二设备认证鉴权为例，第一设备认证第二设备可以理解为：第一设备确定第二设备是否为待组网设备中的设备，在确定第二设备为待组网设备中的设备时，认证通过，可以进行鉴权操作。
认证过程：在一种实施例中，第二设备响应于第二蓝牙广播，在Wi-Fi P2P信道中反馈连接响应消息时，该连接响应消息中可以包括：用于指示第二设备为待组网设备中的设备的标识。示例性的，该连接响应消息中可以包括第二设备的标识，或者其他用于指示第二设备包含于待组网设备的标识，如标志位的数值为1表征第二设备包含于待组网设备。第一设备可以根据该连接响应消息，确定第二设备是否包含于待组网设备。
鉴权过程：在一种实施例中，第一设备和第二设备中均存储有预设密钥，预设密钥如个人身份识别(personal identification number，PIN)码。第一设备对第二设备鉴权，可以理解为：第一设备确定第二设备中的预设PIN是否与第一设备中的预设PIN码相同。
示例性的，第二设备可以采用加密算法，向第一设备发送加密后的第二设备中的预设PIN码，在第一设备解密第二设备中的预设PIN码后，若确定第二设备中的预设PIN码与第一设备中的预设PIN码相同，则第二设备鉴权通过，若第二设备中的预设PIN码与第一设备中的预设PIN码不同，则第二设备鉴权不通过。
在一种实施例中，第一设备还可以采用简单密码指数密钥交换(simple password authenticated exponential key exchange，SPEKE)算法，确定第二设备中的预设PIN码是否与第一设备中的预设PIN码相同。
S310，在第二设备认证通过，以及鉴权通过时，第一设备和第二设备协商得到第一会话密钥。
会话密钥，用于加密以及解密两个设备之间传输的数据。应注意，第一设备和第二设备协商可以得到第一会话密钥，同理的，第一设备和第三设备协商可以得到第二会话密钥，第一会话密钥和第二会话密钥不同。这样，每个群组客户端GC和群组拥有者GO之间的会话密钥不同，可以提高数据安全性。
在一种实施例中，在第二设备认证通过，以及鉴权通过时，第一设备和第二设备可以采用SPEKE算法，协商得到第一会话密钥。其中，SPEKE算法包括两个阶段，密钥交换阶段和密钥认证阶段。在密钥交换阶段，第一设备和第二设备经协商得到会话密钥，在密钥认证阶段，第一设备和第二设备互相确认对方知道的会话密钥，在确认对方知道的会话密钥一致时，可以将该会话密钥作为第一会话密钥。
S311，第一设备采用第一会话密钥加密连接信息，得到第一连接信息。
连接信息可以包括：服务集标识(service set identifier，SSID)和密码。在一种实施例中，连接信息可以称为GO节点信息。
第一设备可以采用第一会话密钥加密连接信息，得到第一连接信息，以保证连接信息的安全。第一连接信息为加密后的连接信息。
本申请实施例中对加解密算法不做限制，加解密算法可以包括但不限于：哈希算法、信息摘要算法 (message-digest algorithm 5，MD5)。
S312，第一设备在Wi-Fi P2P信道上向第二设备发送第一连接信息。
S313，第二设备采用第一会话密钥，解密第一连接信息，得到连接信息。
第二设备解密第一连接信息，可以得SSID和密码。
S314，第二设备在Wi-Fi P2P信道上，采用SSID和密码，接入加密GO(第一设备)。
第二设备在Wi-Fi P2P信道上，采用SSID和密码，可以接入加密GO(第一设备)，即第二设备与第一设备建立加密连接。这样第一设备和第二设备可以在未加密的信道上传输加密的数据，保证数据传输的安全性。
同理的，第一设备可以采用第二会话密钥加密连接信息，得到第二连接信息，以及在Wi-Fi P2P信道上向第三设备发送第二连接信息。第三设备采用第二会话密钥，解密第二连接信息，得到连接信息，如第三设备解密可以得到SSID和密码。第三设备可以在Wi-Fi P2P信道上，采用SSID和密码，接入加密GO(第一设备)。这样第一设备和第三设备可以在未加密的信道上传输加密的数据，可以保证数据传输的安全性。
其中，第二设备、第三设备分别与第一设备建立加密连接，即第一设备、第二设备以及第三设备完成组网。在第一设备、第二设备以及第三设备组网后，第一设备可以通过Wi-Fi P2P信道分别向第二设备、第三设备传输业务数据，保证业务的顺利执行。示例性的，在图1所示的音箱组网后，第一设备(如左置音箱)可以在Wi-Fi P2P信道上向其他音箱发送音频数据，多个音箱可以播放音频，使得用户可以听到具有立体声效果的音频。
图4为本申请实施例提供的音箱组网的一种示意图。参照图4中的a，用户打开音箱，以及打开音箱的蓝牙功能和WLAN功能后，每个音箱可以发送第一蓝牙广播和超声波。应注意，不同音箱发送的超声波的频率不同，图4中的a中未示出超声波的频率。各音箱执行S301-S305后，如确定出的候选主设备为左置音箱和右置音箱，则左置音箱和右置音箱的指示灯闪烁或显示不同颜色，且播放如“按压音箱上的按键，确定组网的主设备”的提示信息，如图4中的b所示。参照图4中的b，若用户按压左置音箱上的按键，则左置音箱可以确定自己是主设备，执行S307-S314，以与各音箱进行无线连接完成组网。
图5为本申请实施例提供的音箱组网的另一种示意图。参照图5，音箱组网的过程可以分为四个阶段，分别为：设备发现阶段、临时连接阶段、认证鉴权阶段，以及业务网络建立阶段。
设备发现阶段，音箱启动BLE扫描，可以发送BLE广播、发射超声波，以及启动超声检测。设备发现阶段可以确定待组网的音箱，以及确定主音箱。主音箱可以通过蓝牙信道公开GO名称和Wi-Fi P2P信道的标识。在一种实施例中，设备发现阶段可以包括S301-S307。
临时连接阶段，从音箱通过Wi-Fi P2P信道与主音箱建立连接，完成Wi-Fi P2P物理链路的建立，即建立Wi-Fi P2P信道。在一种实施例中，临时连接阶段可以包括S308。
认证鉴权阶段，主音箱可以并行对各从音箱进行认证鉴权，以及协商会话密钥。在一种实施例中，临时连接阶段可以包括S309-S310。
业务网络建立阶段，主音箱可以加密连接信息，在非加密的Wi-Fi P2P信道上，将加密后的连接信息传输给各从音箱，各音箱可以与主音箱建立加密连接，完成组网。在一种实施例中，业务网络建立阶段可以包括S311-S314。
图3-图5所示的组网流程为多个设备第一次组网时的流程。以音箱为例，应理解，在各音箱第一次组网后，在下一次各音箱上电时，各从音箱可以在Wi-Fi P2P信道上，采用SSID和密码，直接接入加密主音箱，完成组网。
本申请实施例中，多个设备在组网时，设备可以通过设备发现结合超声检测的方式，确定待组网的设备，待组网的设备可以确定候选主设备，且借助用户的参与确定主设备。在确定主设备之后，主设备可以与从设备之间建立临时连接，在主设备并行认证和鉴权各从设备后，可以协商会话密钥，进而在无线信道上传输加密的数据，使得从设备与主设备建立加密连接，以完成组网。多个设备的组网过程仅需用户确认主设备，操作简单、组网效率高，且各设备之间可以相互连接，无需依赖同一路由器，应用范围广。另外，任一个设备故障，可以及时更换，维护成本低。
在一种实施例中，任一个音箱故障后，用户可以购买同类型的音箱，触发新的音箱和已组网的音箱 重新，或者触发新的音箱加入已组网的音箱中。
其中，若主音箱(如左置音箱)故障，则用户可以购买新的左置音箱，用户可以将其他音箱恢复出厂设置，如用户将低音炮音箱、右置音箱、左环绕音箱和右环绕音箱恢复出厂设置。或者，用户可以在其他音箱上操作(如按键)，以触发其他音箱重新进入组网状态。在其他音箱恢复出厂设置或重新进入组网状态后，其他音箱可以与新购买的左置音箱，按照图3中的流程，进行重新组网。
其中，若从音箱故障，以从音箱为低音炮音箱为例，用户可以购买新的低音炮音箱，且打开低音炮音箱的蓝牙功能和WLAN功能，这样低音炮音箱可以发送第一蓝牙广播和超声波。主音箱监听到来自低音炮音箱的第一蓝牙广播，可以输出第二提示信息，以提示用户是否将扫描到的低音炮音箱加入组网，即提示用户确认是否将低音炮音箱与主音箱连接。若主音箱检测到用户同意将低音炮音箱与主音箱连接的操作，可以执行S307-S314，以使新的低音炮音箱加入组网。在一种实施例中，可以将新的低音炮音箱称为第三设备，第三设备发射的超声波的频率为第三频率。
本申请实施例中，已组网的设备中任一设备故障，用户可以及时更换新的设备，且触发多设备重新组网，操作简便，不影响用户使用。
