本申请涉及通信技术领域，尤其涉及一种Wi-Fi Aware的建链方法、系统、电子设
备和存储介质。
背景技术
Wi-Fi Aware(Wi-Fi Neighborhood Aware Network，Wi-Fi邻居发现网络，又称为Wi-Fi Neighborhood Aware Network，简称NAN)是一种新型的低功耗点对点互连互通的Wi-Fi Mesh通信技术，该技术能够绕开网络基础设施(如AP(Access Point，接入点)或蜂窝网)，实现一对一、一对多或多对多的设备间的连接通信。
在Wi-Fi Aware建链过程中，Wi-Fi Aware规定每间隔512TU(Time Unit，时间单位，1TU＝1024微秒)，会有一个16TU的活动时间窗DW(Discovery Window)。在该活动时间窗期限内，各个Wi-Fi Aware设备方可进行Service Discovery Frame(服务发现帧)、NDP Request Frame(NAN数据通路请求帧，或称为Wi-Fi Aware数据通路请求帧，其中，NDP为NAN Data Path，表示NAN数据传输通路)、NDP Response Frame(NAN数据通路回复帧)、NDP Confirm Frame(NAN数据通路确认帧)、NDP Key Installment Frame(NAN数据通路秘钥安装帧)等Wi-Fi Aware协议中数据帧的交互。两台Wi-Fi Aware设备间若要建链成功，起码要经历4个活动时间窗，间隔耗时在1536TU以上，设备间建链所需的时长较长。

现有技术中，Wi-Fi Aware设备之间进行的数据通信，一般包括如下四步：
步骤一：集群发现。
对于Wi-Fi Aware设备(包括但不限于手机、智能手表、平板电脑和服务器等设备)发现可及范围内的其他Wi-Fi Aware设备，在两个Wi-Fi Aware设备完成建链之前，采用“发现信标帧(Discovery Beacon Frame)”来交互信息，确认可及范围内的其他Wi-Fi Aware设备的存在。
步骤二：时钟同步。
Wi-Fi Aware设备加入其他Wi-Fi Aware设备组成的设备群(集群)，同步发现信标所携带的时间戳。然后，根据该时间戳，计算出活动时间窗发生的具体时间，并在该活动时间窗期间，采用Wi-Fi Aware数据传输通路进行通信。
步骤三：服务发现。
Wi-Fi Aware设备上的应用程序(application，简称APP)利用“发布型(Publish)”和“订阅型(Subscribe)”的Wi-Fi Aware(NAN)服务发现帧(包括服务发现发布帧和服务发现订阅帧)交换信息。Wi-Fi Aware设备可以通过在活动时间窗时期内订阅(搜 索)发现服务，Wi-Fi Aware设备也可以通过在活动时间窗时期内发布(发送)广播表示其存在的信息以及可提供的服务内容。
步骤四：数据建链。
当Wi-Fi Aware设备搜索所需的Wi-Fi Aware服务时，发出搜索的设备可在活动时间窗时期内向检测到的Wi-Fi Aware设备发送数据建链请求，具体可采用Wi-Fi Aware数据通路请求帧的信息交互实现。收到服务请求帧的设备，将在下一活动时间窗期限内回复Wi-Fi Aware数据通路回复帧。其中，若数据建链涉及安全加密，则还需额外在活动时间窗期限内进行Wi-Fi Aware数据通路确认帧和Wi-Fi Aware数据通路秘钥安装帧的信息交互。
Wi-Fi Aware规定每间隔512TU，都会有一个16TU的活动时间窗，在该活动时间窗期限内，各个Wi-Fi Aware设备才可进行服务发现帧、Wi-Fi Aware(NAN)数据通路请求帧、Wi-Fi Aware数据通路回复帧、Wi-Fi Aware数据通路确认帧、Wi-Fi Aware数据通路秘钥安装帧等Wi-Fi Aware协议中数据帧的交互。
如图3所示：主设备将在预定信道上通过广播发现信标帧来让其他设备能够发现其已经创建完成的集群。从设备唤醒并在预定信道上监听发现信标帧，当监听到发现信标帧后，同步自身的Wi-Fi Aware时钟为发现信标帧所携带的Wi-Fi Aware时间戳。
需要说明的是，每个Wi-Fi Aware设备都持有一个精度为“1微秒”的时钟，每微秒该时间戳都自增1。主设备在其发出的发现信标帧时携带自身的时间戳，从设备在收到该主设备发出的发现信标帧后，将自身时钟的时间戳改为与主设备发出的发现信标帧所携带的时间戳一致，可达到主设备和从设备的时钟同步。
可以理解地，每个活动时间窗的开始时间，都是时间戳整除512TU为零的时刻，即每次Value(时间戳)mod512*1024＝0的时刻，都是一个活动时间窗的开始时间，其中，每个活动时间窗持续16TU。进一步地，从设备在活动时间窗期限内，通过发送服务发现帧中的Service Discovery Subscribe Frame(服务发现订阅帧)，主动查询能够提供所需的Wi-Fi Aware服务的设备。主设备在接收从设备发出的服务发现订阅帧后，若判断自身可以提供从设备所需的Wi-Fi Aware服务，则将在下一个活动时间窗回复发送服务发现帧中的Service Discovery Publish Frame(服务发现发布帧)。之后，主设备和从设备之间，将在下两个活动时间窗通过依次交互Wi-Fi Aware数据通路请求帧、Wi-Fi Aware数据通路回复帧、Wi-Fi Aware数据通路确认帧和Wi-Fi Aware数据通路秘钥安装帧完成数据建链。
可以理解地，尽管Wi-Fi Aware进行了低功耗方面的设计，但是如果从设备期望订阅某个Wi-Fi Aware服务，而周边并没有可以提供相应服务的主设备时，将导致从设备定期唤醒自身的Wi-Fi模块，来进行被动监听、发送服务发现订阅帧等操作。显然，频繁唤醒Wi-Fi模块来进行Wi-Fi Aware设备发现，会消耗较多的电池资源。
同时，因为Wi-Fi Aware规定每512TU才有16TU可以进行Wi-Fi Aware数据通路请求帧、Wi-Fi Aware数据通路回复帧、Wi-Fi Aware数据通路确认帧和Wi-Fi Aware数据通路秘钥安装帧等的信息交互，使得两台Wi-Fi Aware设备若要建链成功，起码需要经历4个活动时间窗，间隔耗时在512TU*3＝1536TU以上。
现有技术中，为了解决从设备频繁唤醒Wi-Fi模块来进行Wi-Fi Aware设备发现，会消耗较多电池资源的这个问题，可利用BLE(Bluetooth Low Energy，低功耗蓝牙)实现Wi-Fi Aware设备间的相互发现。具体地，利用BLE具有低功耗、吞吐量较低的特点，Wi-Fi Aware设备间通过BLE广播的方式进行通信。若主设备发送的第一连接信息中包括从设备所需的Wi-Fi Aware服务名，则从设备将唤醒自身的Wi-Fi模块来与主设备进行数据建链。
具体地，如图4所示，从设备在唤醒Wi-Fi模块进行被动监听前，先使用BLE定期广播，在第一连接信息中携带所需Wi-Fi Aware服务的Wi-Fi Aware服务名；若主设备能够提供该Wi-Fi Aware服务，则主设备在接收到该BLE第一连接信息后，也通过BLE广播的方式，告知从设备其能够提供该服务。接着，从设备再唤醒Wi-Fi模块进行被动监听，以监听主设备发出的发现信标帧，然后与图3的步骤相同，完成与主设备的数据建链。
其中，上述BLE是由蓝牙特别兴趣小组于2016年推出的一种超低功耗的用于移动终端的近距离无线通信方案，从下表1中可以看出，无论是在睡眠期间、还是在接收、传输消息时，BLE的工作功耗均小于Wi-Fi，按每天交互10条消息所消耗的功耗来看，BLE的工作功耗仅是Wi-Fi的工作功耗的十分之一，其工作功耗远小于Wi-Fi。
鉴于BLE具有超低功耗，但吞吐量较低的特点，可利用该BLE用于设备间的相互发现。
Figure PCTCN2021080097-appb-000001
表1
可以理解地，尽管采用BLE解决了从设备频繁唤醒Wi-Fi模块来进行Wi-Fi Aware设备发现，会消耗较多电池资源的问题。但是从设备在唤醒Wi-Fi模块后，还是要经过一段时间的被动监听来接收主设备发出的发现信标帧，才能同步到主设备所在集群的时钟，然后再正确地进入活动时间窗来进行Wi-Fi Aware设备发现和数据建链。
可以理解地，采用该BLE也尚未解决Wi-Fi Aware设备发现和数据建链时间较长，超过1536TU的问题。
具体地，可采用如下实施方式解决上述存在的问题。
首先，进行主设备与从设备之间的设备发现。
S11：从设备基于BLE蓝牙模块广播的功能，向主设备发送第一连接信息，其中，第一连接信息包括从设备所需的Wi-Fi Aware服务名，第一连接信息还包括从设备预配置的Wi-Fi Aware参数，其中，从设备预配置的Wi-Fi Aware参数包括Wi-Fi Aware协议中在服务发现订阅帧交互的参数。
S12：主设备基于BLE蓝牙模块广播的功能，接收从设备发送的第一连接信息。
S13：主设备根据从设备所需的Wi-Fi Aware服务名，发送第二连接信息给从设备，其中，第二连接信息包括确认信息，确认信息为主设备确认存在从设备所需的Wi-Fi Aware 服务名的通知信息，从设备根据该确认信息确认主设备存在从设备所需的Wi-Fi Aware服务名，该第二连接信息还包括主设备预配置的Wi-Fi Aware参数，其中，主设备预配置的Wi-Fi Aware参数包括Wi-Fi Aware协议中在服务发现发布帧交互的参数。
在主设备与从设备之间的设备发现完后，通过利用第一连接信息的从设备预配置的Wi-Fi Aware参数、第二连接信息的主设备预配置的Wi-Fi Aware参数，跳过现有技术中服务发现订阅和服务发现推送的步骤，直接执行以下步骤：
S14：主设备获取从设备发送的Wi-Fi Aware数据通路请求帧；
S15：主设备基于Wi-Fi Aware数据通路请求帧与从设备完成建链。
可以理解地，在步骤S11-S13的主设备和从设备间进行Wi-Fi Aware设备发现的交互过程，可采用蓝牙模块实现，具体地，可以采用低功耗蓝牙的蓝牙模块来实现，该低功耗蓝牙具有功耗低、吞吐量低的特点，无论是在休眠期间、还是在接收、传输消息时，低功耗蓝牙的工作功耗远小于Wi-Fi。
其中，主设备和从设备对于设备而言并不是固定不变的，同一台设备既可以作为主设备，也可以作为从设备，具体地，时钟被同步的设备为从设备。
其中，Wi-Fi Aware服务具体可以是指文件共享、照片互传、提供游戏战局加入等服务。
在一实施例中，从设备采用低功耗蓝牙的蓝牙模块与主设备进行Wi-Fi Aware设备发现的交互，相比于原有的唤醒Wi-Fi模块进行被动监听，其消耗的功率更低，且无需Wi-Fi模块不间断地唤醒，能够有效降低设备消耗的电池资源。
其中，BLE蓝牙模块进行广播的第一连接信息通过报文携带。具体地，包括两类报文：广播报文和数据报文。可以理解地，设备利用广播报文发现、连接其它设备。一旦设备连接建立之后，则开始使用数据报文，在一实施例中，从设备所需的Wi-Fi Aware服务名通过数据报文携带。进一步地，数据报文的数据结构为报头结构、数据负载结构(payload)和消息完整性检查结构(Messages Integrity Check，检测MIC)，Wi-Fi Aware服务名具体存储在数据负载结构中。
其中，Wi-Fi Aware服务名是指服务的标识，通过该Wi-Fi Aware服务名能够唯一确定Wi-Fi Aware服务，例如Wi-Fi Aware服务名可以是与文件分享、照片互传或者加入游戏战局相关的名称，其他可唯一确定Wi-Fi Aware服务的标识均可称为Wi-Fi Aware服务名，在这里不仅是对展示的名称的限定，也可以是其他能够唯一确定Wi-Fi Aware服务的标识。
在一实施例中，从设备在广播时已将所需的Wi-Fi Aware服务名携带在第一连接信息中，以让主设备能够通过BLE蓝牙模块接收，获知携带在第一连接信息中的Wi-Fi Aware服务名。
可以理解地，主设备与从设备在进行设备建链之前，将先确定主设备是否能够提供给从设备所需的Wi-Fi Aware服务，若主设备不存在能够提供的Wi-Fi Aware服务，则从设备也不必采用每隔一段时间便唤醒Wi-Fi模块一次的方式实现来被动监听，可以在确定主设备存在从设备所需的Wi-Fi Aware服务时再唤醒Wi-Fi模块进行被动监听，从而有效地减少电源的消耗。
在一实施例中，在主设备接收从设备的第一连接信息后，将根据第一连接信息中的Wi-Fi Aware服务名来确定自身是否能够为从设备提供所需的第一连接信息服务，若不能，BLE蓝牙模块可选择进入休眠状态，减少设备电池资源的消耗。
具体地，主设备将通过字符串比对的方式确定是否能够为从设备提供所需的第一连接信息服务。可以理解地，Wi-Fi Aware服务名是指Wi-Fi Aware服务的标识，通过该Wi-Fi Aware服务名能够唯一确定Wi-Fi Aware服务，例如在加入游戏战局的场景中，Wi-Fi Aware服务名包括游戏名称、游戏版本号和用于表示提供Wi-Fi Aware服务的服务标识，从设备将根据所需的第一连接信息服务发送Wi-Fi Aware服务名，若主设备通过字符串比对发现自身能够提供的Wi-Fi Aware服务与从设备所需的Wi-Fi Aware服务能够匹配上的，则主设备存在从设备所需的Wi-Fi Aware服务。
在步骤S11-S13中，通过利用BLE蓝牙模块进行主设备和从设备间Wi-Fi Aware设备发现的交互，能够有效降低设备消耗的电池资源，并在设备进行建链之前，预先确定主设备是否存在从设备所需的Wi-Fi Aware服务，可让BLE蓝牙模块无需一直处于激活的状态，有效降低设备消耗的电池资源。
其中，在Wi-Fi Aware设备发现的交互过程中(步骤S11-S13)，第一连接信息还包括从设备预配置的Wi-Fi Aware参数，其中，从设备预配置的Wi-Fi Aware参数包括Wi-Fi Aware协议中在服务发现订阅帧交互的参数；第二连接信息还包括主设备预配置的Wi-Fi Aware参数，其中，主设备预配置的Wi-Fi Aware参数包括Wi-Fi Aware协议中在服务发现发布帧交互的参数。
进一步地，Wi-Fi Aware协议中在服务发现订阅帧交互的参数包括从设备的Wi-Fi Aware管理口MAC地址、从设备的Wi-Fi Aware标识，以及从设备的数据加密预配置信息，Wi-Fi Aware协议中在服务发现发布帧交互的参数包括主设备的Wi-Fi Aware管理口MAC地址、主设备的Wi-Fi Aware标识，以及主设备的数据加密预配置信息。
其中MAC地址(Media Access Control Address)称为局域网地址或物理地址(Physical Address)，是一个用来确认网络设备位置的位址。Wi-Fi Aware标识是指能够唯一识别Wi-Fi Aware使用对象的标识，例如可以采用ID的方式表示。数据加密预配置信息是指预先配置的数据加密方式(如数据的加密算法)，如主设备获知从设备的数据加密预配置信息，则可根据该数据加密预配置信息解密从从设备获取得到的数据。
可以理解地，主设备和从设备均可包括Wi-Fi Aware管理口MAC地址、Wi-Fi Aware标识、以及数据加密预配置信息等的信息。主设备和从设备可根据这些信息进行数据建链，实现信息交互。
进一步地，第二连接信息还包括主设备的Wi-Fi Aware时间戳，用于同步从设备的时钟。
其中，Wi-Fi Aware时间戳的长度具体可以是8字节长度。每过1微秒，时间戳将自增1。
从图4中可以看出，在从设备确定主设备能够提供所需的Wi-Fi Aware服务后，仍需经历被动监听的过程，来实现时钟同步。在一实施例中，在主设备和从设备间进行Wi-Fi Aware设备发现的交互过程中，其交互的第二连接信息还包括主设备的Wi-Fi Aware时间 戳，从设备可根据该Wi-Fi Aware时间戳将自身的时钟同步为主设备的时钟。可以理解地，当主设备和从设备的时钟一致后，才能够在相同的活动时间窗内进行信息交互。
可以理解地，在现有技术中设备进行Wi-Fi Aware建链的协议时，包括固定的以下步骤：从设备的服务发现订阅和主设备的服务发现发布(服务发现订阅采用服务发现订阅帧的方式传输数据，服务发现发布采用服务发现发布帧的方式传输数据)，该两个步骤是为了主设备和从设备建立起信息交互的基础，通过如设备的Wi-Fi Aware管理口MAC地址、Wi-Fi Aware标识等确定与连接设备的信息，使得设备之间能够根据这些信息进行信息交互。需要说明的是，该服务发现订阅和服务发现发布与Wi-Fi Aware设备发现不同，Wi-Fi Aware设备发现是为了确认主设备是否存在从设备所需的Wi-Fi Aware服务，仅是为了预先确定可提供的Wi-Fi Aware服务，以及对应的提供服务的设备是否存在。
可以理解地，在现有技术中由于建链过程采用服务发现订阅和服务发现发布步骤的缘故，使得建链的时长较长，需要经历至少两个活动时间窗才能完成。
在一实施例中，在Wi-Fi Aware设备发现的交互过程中，将主设备和从设备建链的Wi-Fi Aware协议中在服务发现订阅帧交互的参数、Wi-Fi Aware协议中在服务发现发布帧交互的参数也进行了交互，使得从设备在确定主设备是否能提供所需的Wi-Fi Aware服务时，已预先进行Wi-Fi Aware协议中在服务发现订阅帧交互的参数、Wi-Fi Aware协议中在服务发现发布帧交互的参数的交互，可跳过服务发现订阅和服务发现发布的步骤，直接进行后续的建链步骤(步骤S14-S15)，从而提高设备间的建链效率。
可以理解地，当主设备存在从设备所需的Wi-Fi Aware服务时，主设备可与从设备直接根据第一连接信息和第二连接信息进行后续的建链操作，无需再间隔至少两个活动时间窗来交互Wi-Fi Aware协议中在服务发现订阅帧交互的参数、Wi-Fi Aware协议中在服务发现发布帧交互的参数。主设备可与从设备，根据如Wi-Fi Aware管理口MAC地址、Wi-Fi Aware标识等的信息完成建链，省去服务发现订阅和服务发现发布的步骤。
进一步地，本方法还具体包括如下步骤：
根据主设备发送到从设备的Wi-Fi Aware时间戳，将从设备时钟的时间戳调整为和主设备的Wi-Fi Aware时间戳一致。
在一实施例中，同步时钟的方式具体可以是将从设备的Wi-Fi Aware时间戳与主设备的Wi-Fi Aware时间戳同步更新，使得从设备的Wi-Fi Aware时间戳和主设备的Wi-Fi Aware时间戳一致。
进一步地，在步骤S15中，即主设备基于Wi-Fi Aware数据通路请求帧与从设备完成建链，具体包括：
S211：主设备根据从设备预配置的Wi-Fi Aware参数判断Wi-Fi Aware数据通路请求帧是否来自从设备，若是，在下一个活动时间窗，向从设备发送Wi-Fi Aware数据通路回复帧。
S212：从设备接收Wi-Fi Aware数据通路回复帧后，主设备与从设备完成建链。
在一实施例中，主设备需要对Wi-Fi Aware数据通路请求帧的来源进行判断，若判断通过，则回复从设备，具体为向从设备发送Wi-Fi Aware数据通路回复帧。
进一步地，主设备在判断Wi-Fi Aware数据通路请求帧来自从设备之后，还可以根据预设的处理方式，拒绝回复从设备，例如，主设备预先设置了“拒绝与任何设备进行 Wi-Fi Aware建链”的处理方式，则即使确认Wi-Fi Aware数据通路请求帧来自从设备，也不会回复从设备。
S211-S212中，提供了一种主设备基于Wi-Fi Aware数据通路请求帧与从设备完成建链的具体实施方式，通过Wi-Fi Aware数据通路请求帧和Wi-Fi Aware数据通路回复帧完成数据建链。
进一步地，如果建链后数据交互的过程中要求进行数据加密，则主设备基于Wi-Fi Aware数据通路请求帧与从设备完成建链，具体包括：
S221：主设备根据从设备预配置的Wi-Fi Aware参数判断Wi-Fi Aware数据通路请求帧是否来自从设备，若是，在下一个活动时间窗，向从设备发送Wi-Fi Aware数据通路回复帧。
S222：主设备判断从设备预配置的Wi-Fi Aware参数中是否包括从设备的数据加密预配置信息，若存在，主设备等待获取从设备发送的Wi-Fi Aware数据通路确认帧。
S223：从设备判断主设备预配置的Wi-Fi Aware参数中是否包括数据加密预配置信息，若存在，从设备向主设备发送Wi-Fi Aware数据通路确认帧。
S224：主设备根据从设备预配置的Wi-Fi Aware参数判断Wi-Fi Aware数据通路确认帧是否来自从设备，若是，主设备向从设备发送Wi-Fi Aware数据通路秘钥安装帧。
S225：从设备接收Wi-Fi Aware数据通路秘钥安装帧，与主设备完成建链。
可以理解地，如果建链后数据交互的过程中要求进行数据加密，则在建链过程中主设备将为从设备提供秘钥安装，具体采用发送Wi-Fi Aware数据通路秘钥安装帧实现，以使从设备能够根据该Wi-Fi Aware数据通路秘钥安装帧完成秘钥安装，主设备和从设备之间可按照两者约定的加密方式进行数据交互。
在步骤S221-S225中，提供了一种主设备基于Wi-Fi Aware数据通路请求帧与从设备完成建链的具体实施方式，通过Wi-Fi Aware数据通路请求帧、Wi-Fi Aware数据通路回复帧、Wi-Fi Aware数据通路确认帧和Wi-Fi Aware数据通路秘钥安装帧完成数据建链。
在一实施例中，图5示出了Wi-Fi Aware通过应用程序完成建链的一流程图。
从图5可以看出，本申请通过在Wi-Fi Aware设备发现的过程中，预先交互了主设备和从设备预配置的Wi-Fi Aware参数(先在Wi-Fi模块获取Wi-Fi Aware接口参数，再将接口参数、和设备本身具有的Wi-Fi Aware参数作为第一连接信息或者第二连接信息下发到BLE模块)，跳过了虚线框中服务发现订阅和服务发现发布的步骤，直接进行Wi-Fi Aware数据通路请求帧、Wi-Fi Aware数据通路回复帧、Wi-Fi Aware数据通路确认帧、Wi-Fi Aware数据通路秘钥安装帧等Wi-Fi Aware协议中数据帧的交互，完成数据建链，有效提高了的建链效率。
在一实施例中，图6示出了Wi-Fi Aware通过应用程序完成建链的又一流程图，图6中示出的步骤具体如下：
其中，由于本申请涉及的具体技术为Wi-Fi Aware，为简便表示，例如Wi-Fi Aware(NAN)数据通路请求帧可简洁表示为数据通路请求帧，省去前缀。

S307：主设备的BLE模块接收到从设备在步骤S306发出的广播BLE报文，匹配到双方的Wi-Fi Aware服务名相同，将从设备消息携带的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址、Wi-Fi Aware安全预配置参数上报到主设备的Wi-Fi Aware APK，主设备的Wi-Fi Aware APK将根据自身策略决定是否响应收到的BLE报文。如果决定响应，则进行步骤S308，否则，返回步骤S303。
其中，主设备的Wi-Fi Aware APK的自身策略包括对黑名单的拒绝响应，以及白名单的响应，若从设备消息携带的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址中任一项存在黑名单中，则主设备决定不响应，返回步骤S303；若从设备消息携带的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址中均存在白名单中，将决定响应，进行步骤S308。

在一实施例中，具有Wi-Fi Aware功能的设备可以在没有Wi-Fi、AP或蜂窝网的情况下完成数据交互。
具体地，如图7所示，移动终端A和移动终端B在有限距离内可通过Wi-Fi Aware功能实现设备之间的通信，其中，该Wi-Fi Aware功能的使用包括但不限于以下的方式：
文件分享：可以理解地，用户可以通过移动终端A与移动终端B完成Wi-Fi Aware的数据建链，使得用户可将移动终端B所要获取的文档文件、图片文件、视频文件等通过移动终端A发送过去。具体地，在没有Wi-Fi或者Wi-Fi信号差的地方、如演唱会现场、篮球馆、音乐厅等可采用该Wi-Fi Aware完成建链，实现设备间的连接通信。此外，设备间建链的时长较快，且电池资源消耗较低。
具体地，包括如下步骤：
移动终端A在开启文件分享的相关应用程序后，从Wi-Fi模块中获取Wi-Fi Aware参数，包括：Wi-Fi Aware管理口MAC地址，Wi-Fi Aware时间戳。
移动终端A下发如下预配置的Wi-Fi Aware参数到BLE蓝牙模块：文件分享(文档、图片和视频等)的Wi-Fi Aware服务名、Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址，Wi-Fi Aware安全预配置参数，Wi-Fi Aware时间戳。
移动终端A的BLE蓝牙模块，根据下发的预配置的Wi-Fi Aware参数，被动监听周边的广播BLE消息，识别是否有匹配可进行服务的Wi-Fi Aware设备。

移动终端A的BLE模块接收到移动终端B发出的广播BLE报文，匹配到双方文件分享的服务名相同，将移动终端B消息携带的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址、Wi-Fi Aware安全预配置参数上报到移动终端A，移动终端A将根据自身策略决定是 否响应收到的BLE报文。如果决定响应，则继续执行以下剩余步骤，否则，返回被动监听周边的广播BLE消息，识别是否有匹配可进行服务的Wi-Fi Aware设备的步骤。
移动终端A通过BLE蓝牙模块回复移动终端B的广播，同时携带自身的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址、Wi-Fi Aware安全预配置参数、Wi-Fi Aware时间戳。
移动终端B收到移动终端A通过BLE广播回复的报文，然后将报文携带的移动终端A的Wi-Fi Aware ID、Wi-Fi Aware管理口MAC地址、Wi-Fi Aware安全预配置参数、Wi-Fi Aware时间戳上报到移动终端B。

移动终端B的Wi-Fi模块根据Wi-Fi Aware时钟，在计算出的下一个活动时间窗唤醒，发送数据通路请求帧到移动终端A，进行数据建链请求。
移动终端A收到移动终端B的数据通路请求帧后，判断该数据通路请求帧发出者是否为移动终端B，如果是，则回复数据通路回复帧，否则移动终端A的Wi-Fi模块根据Wi-Fi Aware时钟，在计算出的下一个活动时间窗唤醒，进行被动监听的步骤。
如果移动终端B接收到移动终端A回复的数据通路回复帧，则继续发送数据通路确认帧。
如果移动终端A接收到移动终端B发来的数据通路确认帧，同时移动终端B确认匹配成功，则回复数据通路秘钥安装帧，此时完成Wi-Fi Aware数据建链。
进一步地，Wi-Fi Aware功能的使用还包括如加入游戏战局的方式。可以理解地，有些游戏是需要联网对战的，在没有Wi-Fi等网络的情况下，可以采用Wi-Fi Aware功能实现联网。具体地，提供游戏战局加入也是一种可提供的服务，而加入游戏战局则为一种设备所期望的Wi-Fi Aware服务。例如，移动终端A通过Wi-Fi Aware提供了加入游戏战局的服务，则移动终端B的用户若要与移动终端A的用户一同联网玩游戏，则可通过Wi-Fi Aware表明移动终端B所期望的服务-加入游戏战局。具体Wi-Fi Aware建链的步骤与上述文件分享的Wi-Fi Aware建链步骤类似，在此不再赘述。同样地，在本实施例中可在服务发现的过程中便获取原本服务发现订阅和服务发现发布步骤交互的信息、时钟同步信息，使得在实现Wi-Fi Aware建链的过程中，设备间建链的时长较快，且电池资源消耗较低。
在本申请实施例中，主设备与从设备进行设备发现的交互，以确定主设备是否能提供从设备所需的Wi-Fi Aware服务，当主设备能够提供从设备所需的Wi-Fi Aware服务时，从设备才会与主设备进行下一步的建链步骤；其中，在Wi-Fi Aware设备发现的交互过程中，利用第一连接信息和第二连接信息的交互，在设备发现过程中便得到主设备和从设备 在现有技术建链步骤中，Wi-Fi Aware协议中在服务发现订阅帧和服务发现发布帧交互的参数。在Wi-Fi Aware设备发现阶段已得到Wi-Fi Aware协议中在服务发现订阅帧和服务发现发布帧交互的参数的情况下，主设备和从设备能够跳过服务发现订阅和服务发现发布的步骤，更快地完成Wi-Fi Aware的建链，有效提高Wi-Fi Aware设备间建链的速度。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。

可以理解地，在现有技术中，Wi-Fi Aware协议中在服务发现订阅帧交互的参数、Wi-Fi Aware协议中在服务发现发布帧交互的参数需通过Wi-Fi Aware协议中服务发现订阅和服务发现发布交互的步骤得到，而在本申请实施例中，将Wi-Fi Aware协议中在服务发现订阅帧交互的参数、Wi-Fi Aware协议中在服务发现发布帧交互的参数在Wi-Fi Aware设备发现的过程中便进行交互，可令主设备和从设备跳过服务发现订阅和服务发现发布交互的步骤，直接根据第一连接信息和第二连接信息进行数据建链，有效提高了建链的速度。
