为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
无线保真临近感知网络(Wireless-Fidelity Neighborhood Aware Network，Wi-Fi NAN)又称无线保真感知(Wireless-Fidelity Aware，Wi-Fi Aware)，Wi-Fi Aware是Wi-Fi联盟制定的临近感知网络标准，可以在没有Wi-Fi接入点的情况下，可以进行临近设备发现。Wi-Fi Aware通过“发布(Publish)”和“订阅(Subscribe)”消息交换信息，一旦检测到设备和想要的服务，发出检测的设备就可向这些检测到的设备发送提示信息。
图1为本申请实施例提供的一种由多个物联网设备组成的簇的示意图，如图1所示，在簇Cluster(又称为邻近感知网络)中存在多个物联网设备，Cluster内的任一个物联网设备能够发现其它物联网设备和/或被其它物联网设备发现，以建立该任一个物联网设备与其它物联网设备的连接。在本申请实施例中，可以实现支持Matter标准的物联网设备能够发现彼此并建立连接。例如，Cluster内的第一设备和第二设备可以基于Matter标准或者Matter协议建立连接。
Matter协议是一个应用层协议。Matter可以以无线保真(Wireless-Fidelity，Wi-Fi)、 Thread、蓝牙(Bluetooth)、Cellular，Ethernet、以太网等、紫蜂(Zigbee)、Z-Wave作为网络层/传输层协议通信协议，本申请实施例并不限制Matter对应的网络层/传输层协议。在一些实施例中，至少两个设备间可以通过蓝牙、Wi-Fi或Thread等加入到Matter网络。
此处对临近感知网络(Neighbor Awareness Network，NAN)机制进行简要的介绍：NAN机制是无线保真Wi-Fi联盟制订的一个标准，这个标准的作用是在没有中心节点的情况下，使得所有参与NAN机制的设备(即NAN设备)同步起来，在NAN机制约定的发现窗口(Discovery Window，DW)中进行NAN机制的维持工作和服务发现工作。
在Wi-Fi联盟指定的标准中，在NAN机制中可以以第6信道为发现信道，在第6信道上，对于每个簇而言，发现窗口DW的时长是固定的，且该簇的任意相邻的两个DW之间的时间间隔也是固定的。
NAN机制一般每512个TU(time unit，时间单元)内设置有一个DW，其中一个TU的持续时长大约为1024μs，DW的持续时长一般为16TU，即在NAN机制中，一般每隔496个TU设置一个DW。在NAN机制中，一个或多个NAN设备形成一个簇Cluster，一个Cluster在进入DW时，由该Cluster中处于主节点(Master)、锚主节点(Anchor Master，AM)、以及负责同步的主节点(Non-Master Synchronization，Non-Master Sync)状态等的NAN设备发送同步信标帧(Sync Beacon)消息，该消息中携带有该Cluster中的AM的信息，用于接收到该消息的NAN设备与该Cluster中的AM实现同步。
在DW中，该簇中的NAN设备可以在DW中发送服务发现帧(Service Discovery Frames，SDF)消息，进行服务发现，在DW以外的时间中，该簇中的NAN设备可以发送发现信标(discovery beacon)消息，以宣告该簇的存在。
NAN设备服务发现的流程如下：
1、一个设备激活NAN功能后(即成为NAN设备后)，可以将自身设置为AM，创建一个Cluster，并基于自身的介质访问控制(Media Access Control，MAC)地址设定该Cluster的Cluster身份标识(Identity，ID)值，将时间同步功能(Time Synchronization Function，TSF)设置为512TU的整数倍。
2、一旦该NAN设备接收到来自一个或多个其他Cluster的NAN设备发送的Beacon帧(即sync beacon，以下统一称为Beacon帧)时，就可以判断自己是否要加入对方的Cluster。
在Beacon帧中，一般携带有相应的Cluster的信息，具体可以是相应的Cluster中的AM的信息，例如可以包括锚主节点等级(Anchor Master Rank，AMR)、主节点等级(Master Rank，MR)、主节点优先权(Master Preference，MP)、锚主节点优先权(Anchor Master Preference，AMP)、随机因素(Random Factor，RF)、锚主节点信号传输时间(Anchor Master Beacon Transmission Time，AMBTT)、时间同步功能TSF、簇身份标识(Cluster ID)、以及簇等级(Cluster grade，CG)中的一种或多种。
一个NAN设备可以通过发送Beacon帧将自己所属的Cluster的AM的信息发送给其他的NAN设备，同样，一个NAN设备也可以接收本Cluster或其他Cluster中的NAN设备发送的Beacon帧。
在NAN设备接收到一个Beacon帧后，可以判断该Beacon帧是来自自身所属的Cluster中的NAN设备还是来自其他Cluster中的NAN设备，若是来自其他Cluster中的NAN设备，则该NAN设备可以判断接收的Beacon帧中的簇等级CG的值是否大于自身的簇等级CG的值，若大于，则该NAN设备加入该接收的Beacon帧对应的Cluster，否则，该NAN设备不做处理。这就完成了NAN设备的聚合，即，NAN设备会加入簇 等级CG的值较高(例如，簇等级CG的值最高)的Cluster。
3、若判断确定要加入对方的Cluster，则在加入对方的Cluster之后与加入的Cluster中的AM实现同步，例如可以是将自身的AM中的各项参数信息与加入的Cluster中的AM同步，例如将自身原有的时间同步功能TSF更新为加入的Cluster中的AM的TSF等。
4、在同步后，当加入的Cluster的DW到来时，该NAN设备在DW中发送SDF消息以进行服务发现，该SDF消息中例如可以携带有用于发布该NAN设备所能够提供的服务对应的服务发布(Service Publish)信息，其他NAN设备在接收到该NAN设备发送的SDF消息后，若确定满足该SDF消息，即能够进行服务匹配，则可以在DW中向该NAN设备回复SDF消息。
同样的，在DW中，该NAN设备也可能会接收到其他NAN设备发送的用于进行服务发现的SDF消息，若该NAN设备确定满足所接收的SDF消息，则该NAN设备也会在DW中向相应的NAN设备回复SDF消息。
以下对AM中包含的各类信息进行解释。
锚主节点等级AMR，一般最大取值为8个字节(byte)，是AM的MR的值。
主节点等级MR，一般最大取值为8个字节，是根据MP值、RF值以及本NAN设备的MAC地址计算得出，表示该NAN设备想当master的意愿。MR的值越大，表明该NAN设备想当master意愿越高。MR也可以看做是MP的另外表达形式。
主节点优先权MP，一般最大取值为1个字节，表明本NAN设备想当master的意愿。MP的值越大，表明该NAN设备想当master意愿越高。
锚主节点优先权AMP，一般最大取值为1个字节，是AM的MP的值。
随机因素RF，一般最大取值为1个字节，是NAN设备选择的随机数。
锚主节点信号传输时间AMBTT，一般最大取值为4个字节，表明AM的Beacon帧的发送时间。一般来说，发送Beacon帧的NAN设备会携带有AMBTT，用于其他NAN设备与该AMBTT对应的AM的时间实现同步。
时间同步功能TSF，一般最大取值为8个字节，表明NAN设备的同步功能，使得接收到该TSF的NAN设备的计时器(timer)与发送该TSF的NAN设备对应的AM的时间实现同步。TSF也可以表示时间信息。
簇身份标识Cluster ID，一般最大取值为6个字节，将其携带在Beacon帧中的Address(地址)3的字段中。
簇等级CG，一般最大取值为8个字节，表示Cluster的等级，用于不同的Cluster在合并时进行比较，CG的值小的Cluster合并到CG的值大的Cluster中。
以下介绍服务发现帧SDF消息。
SDF消息是一种专门定义用来做服务发现的动作帧(Action Frame)，根据功能不同，SDF消息大致可以分为三种：SDF发布Publish消息、SDF订阅Subscribe消息、SDF回复Follow-Up消息，一般来说，在SDF消息中包括一个指示位，用于指示该SDF消息是哪种SDF消息。
SDF Publish消息：用于发布NAN设备所能提供的服务，或用于回复收到的其他NAN设备发送的SDF Subscribe消息；
SDF Subscribe消息：用于查找需要使用的服务；
SDF Follow-Up消息：用于回复收到的SDF Publish消息，或者用于协商更多的信息。
本申请实施例中的第一物联网服务信息和第二物联网服务信息可以都支持Matter，从而第一设备可以根据第二设备发送的包括或指示Matter协议的标识或名称的第一物 联网服务信息，与第二设备建立基于Matter协议的连接。
在一些实施例中，基于Matter协议的连接，可以包括以下之一：基于Matter协议的蓝牙连接、基于Matter协议的Wi-Fi连接、基于Matter协议的Thread连接、基于Matter协议的Cellular连接、基于Matter协议的Ethernet连接、基于Matter协议的以太网连接、基于Matter协议的其它网络层/传输层协议连接等等。本申请并不限定Matter协议所对应的网络层/传输层协议，只要第一设备和第二设备之间能够建立基于Matter协议的连接即可。
Matter物联网标准是连接标准联盟(Connectivity Standards Alliance，CSA)制定的基于网际互连协议(Internet Protocol，IP)的智能家居连接标准，解决智能家居市场存在的兼容性、安全性和连接性等问题。Matter标准目前采用的设备发现为基于组播域名系统(multicast Domain Name System，mDNS)，组播域名系统又称多播域名系统/域名系统服务发现(DNS Service Discovery，DNS-SD)的设备发现，其是通过基于域名系统的mDNS/DNS-SD查询的方式以获得Matter设备及其服务信息。
例如，Matter设备mDNS记录中包括Matter相关的mDNS服务(SRV)、指针(PTR)和文本(TXT)记录等信息。SRV记录是可用于指定关于域中可用的服务的信息的资源记录。在SRV记录中，名称字段可用于指示服务的标识信息，诸如服务的名称、服务所使用的协议(诸如通用数据报协议(User Datagram Protocol，UDP)或传输控制协议(Transmission Control Protocol，TCP))。PTR记录是用于指向域名空间中的位置的资源记录。在PTR记录中，可以使用RDATA字段来存储所指向的位置。TXT记录可用于保留描述性文本。在TXT记录中，描述性文本可包括在RDATA字段中。
Matter设备发现机制需要物联网设备支持IP，不支持IP的物联网设备则无法进行Matter设备发现，另外Matter设备发现需要创建并维护Matter相关的mDNS/DNS-SD SRV、PTR和TXT记录等信息，对于低功耗、存储和计算资源受限的物联网设备，存在无法负担基于mDNS/DNS-SD的设备发现机制的可能性。
在本申请实施例中，通过SDF消息进行物联网服务信息的指示，从而能够通过SDF消息实现Matter设备的发现，进而实现Matter设备之间的连接。
本申请实施例采用SDF消息中的SDF Publish消息或者SDF Subscribe消息，对本申请实施例中的通信方法进行说明。
本申请实施例中的第一设备和/或第二设备可以是上述提到的的物联网设备、NAN设备或Matter设备。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
