The Wireless fidelity proximity sensing network (Wi-Fi NAN) is also called Wireless fidelity (Wireless-FIDELITY AWARE, wi-Fi Aware), which is a proximity sensing network standard formulated by Wi-Fi alliance, and can perform proximity device discovery without Wi-Fi access point. Wi-Fi Aware exchanges information via "Publish" and "Subscribe" messages, and once a device and a desired service are detected, the device that sent the detection may send a hint to those detected devices.

Fig. 1 is a schematic diagram of a Cluster formed by a plurality of internet of things devices according to an embodiment of the present application, as shown in fig. 1, there are a plurality of internet of things devices in a Cluster (also referred to as a proximity sensing network), and any one of the internet of things devices in the Cluster can discover other internet of things devices and/or be discovered by other internet of things devices, so as to establish connection between the any one of the internet of things devices and the other internet of things devices. In the embodiment of the application, the Internet of things equipment supporting the Matter standard can find each other and establish connection. For example, the first device and the second device within the Cluster may establish a connection based on the Matter standard or the Matter protocol.

The Matter protocol is an application layer protocol. The Wireless-Fidelity (Wi-Fi), thread, bluetooth (Bluetooth), cellular, ethernet, etc., zigbee, Z-Wave may be used as the network layer/transport layer protocol communication protocol, and the embodiment of the present application does not limit the network layer/transport layer protocol corresponding to the Wireless-Fidelity (Wi-Fi), bluetooth, ethernet, etc., and Zigbee, Z-Wave may be used as the network layer/transport layer protocol communication protocol. In some embodiments, at least two devices may join the Matter network via Bluetooth, wi-Fi, or Thread, among others.

A brief introduction is made here to the proximity-aware network (Neighbor Awareness Network, NAN) mechanism: the NAN mechanism is a standard formulated by the Wi-Fi alliance of wireless fidelity, and the function of this standard is to synchronize all devices participating in the NAN mechanism (i.e., NAN devices) without a central node, and perform maintenance work and service Discovery work of the NAN mechanism in Discovery Windows (DWs) agreed by the NAN mechanism.

In the standard specified by Wi-Fi alliance, the 6 th channel may be used as a discovery channel in the NAN mechanism, on the 6 th channel, the duration of the discovery window DW is fixed for each cluster, and the time interval between any two adjacent DWs of the cluster is also fixed.

NAN mechanisms typically have one DW per 512 TUs (time units), where one TU has a duration of about 1024 μs and DW has a duration of typically 16 TUs, i.e., in NAN mechanisms, one DW is typically set every 496 TUs. In the NAN mechanism, one or more NAN devices form a Cluster, and when entering a DW, a NAN device in the Cluster, which is in a Master node (Master), an Anchor Master (AM), and a Master node (Non-Master Synchronization, non-MASTER SYNC) state responsible for synchronization, sends a synchronization Beacon (Sync Beacon) message, where the message carries information of an AM in the Cluster, and the NAN device for receiving the message synchronizes with the AM in the Cluster.

In the DW, NAN devices in the cluster may send a service discovery frame (Service Discovery Frames, SDF) message in the DW to conduct service discovery, and in times other than the DW, NAN devices in the cluster may send a discovery beacon (discovery beacon) message to announce the existence of the cluster.

The procedure of NAN device service discovery is as follows:

1. After a device activates the NAN function (i.e., becomes a NAN device), it may set itself to AM, create a Cluster, and set a Cluster Identity (ID) value of the Cluster based on its own media access Control (MEDIA ACCESS Control, MAC) address, and set the time synchronization function (Time Synchronization Function, TSF) to an integer multiple of 512 TU.

2. Once the NAN device receives a Beacon frame (i.e., a sync Beacon, hereinafter collectively referred to as a Beacon frame) sent by the NAN device from one or more other Cluster devices, it can determine whether to join the Cluster of the other party.

In Beacon frames, information of a corresponding Cluster is generally carried, and may specifically be information of an AM in the corresponding Cluster, which may include, for example, one or more of an Anchor master node level (Anchor MASTER RANK, AMR), a master node level (MASTER RANK, MR), a master node priority (MASTER PREFERENCE, MP), an Anchor master node priority (Anchor MASTER PREFERENCE, AMP), a Random Factor (RF), an Anchor master node signal transmission time (Anchor Master Beacon Transmission Time, AMBTT), a time synchronization function TSF, a Cluster identity (Cluster ID), and a Cluster level (Cluster grade, CG).

One NAN device may send information of AM of its own Cluster to other NAN devices by sending Beacon frames, and likewise, one NAN device may receive Beacon frames sent by the NAN devices in the present Cluster or other clusters.

After the NAN device receives a Beacon frame, it can determine whether the Beacon frame is from a NAN device in a Cluster to which the NAN device belongs or from a NAN device in another Cluster, if so, the NAN device can determine whether the value of the Cluster level CG in the received Beacon frame is greater than the value of the Cluster level CG of the NAN device, if so, the NAN device joins the Cluster corresponding to the received Beacon frame, otherwise, the NAN device does not process. This completes the aggregation of NAN devices, i.e., the NAN device will join the Cluster with a higher value for Cluster level CG (e.g., highest value for Cluster level CG).

3. If it is determined that the Cluster of the other party is to be added, synchronization with the AM in the added Cluster is implemented after the Cluster of the other party is added, for example, each item of parameter information in the AM of the other party may be synchronized with the AM in the added Cluster, for example, the TSF of the original time synchronization function of the other party is updated to the TSF of the AM in the added Cluster.

4. After synchronization, when the DW of the joining Cluster arrives, the NAN device sends an SDF message in the DW to perform Service discovery, where the SDF message may, for example, carry Service publishing (Service publishing) information corresponding to a Service that can be provided by the NAN device, and after receiving the SDF message sent by the NAN device, other NAN devices may reply to the NAN device in the DW if it is determined that the SDF message is satisfied, that is, service matching can be performed.

Similarly, in the DW, the NAN device may also receive SDF messages sent by other NAN devices for service discovery, and if the NAN device determines that the received SDF message is satisfied, the NAN device replies an SDF message to the corresponding NAN device in the DW.

The various information contained in the AM is explained below.

The anchor master level AMR, which is typically 8 bytes (byte) at maximum, is the value of the MR of AM.

The master node level MR, which is typically 8 bytes in maximum, is calculated from the MP value, the RF value, and the MAC address of the NAN device, and indicates the willingness of the NAN device to function as a master. The larger the value of MR, the higher the NAN device wants to be as master. MR can also be seen as an additional expression of MP.

The master node priority MP, which is typically 1 byte at maximum, indicates the willingness of the present NAN device to function as a master. The larger the MP value, the higher the NAN device wants to be when master.

The anchor master node priority AMP is typically 1 byte maximum and is the value of MP of AM.

The random factor RF, which is typically 1 byte at maximum, is a random number selected by the NAN device.

The anchor master node signal transmission time AMBTT, which is typically a maximum of 4 bytes, indicates the time of transmission of the Beacon frame of the AM. Generally, the NAN device sending the Beacon frame will carry AMBTT for synchronizing other NAN devices with the time of the AM corresponding to AMBTT.

The time synchronization function TSF, which is typically 8 bytes at maximum, indicates the synchronization function of the NAN device, so that a timer (timer) of the NAN device that receives the TSF is synchronized with the time of the AM corresponding to the NAN device that transmits the TSF. TSF may also represent time information.

The Cluster ID, which is typically a maximum of 6 bytes, is carried in the Address 3 field of the Beacon frame.

Cluster level CG, which is typically 8 bytes at maximum, represents the level of a Cluster, and is used for comparing different clusters when merging, where clusters with smaller CG values are merged into clusters with larger CG values.

The service discovery frame SDF message is introduced below.

SDF messages are a type of Action Frame (Action Frame) specifically defined for service discovery, and can be roughly divided into three types according to functions: the SDF issues a Publish message, the SDF subscribes to a Subscribe message, and the SDF replies to the Follow-Up message, typically including an indicator bit in the SDF message to indicate which SDF message the SDF message is.

SDF Publish message: the SDF subscore message is used for publishing services which can be provided by the NAN equipment or replying to SDF subscore messages sent by other NAN equipment;

SDF Subscribe message: for searching for a service to be used;

SDF Follow-Up message: for replying to received SDF Publish messages, or for negotiating more information.

According to the embodiment of the application, the first Internet of things service information and the second Internet of things service information can both support the Matter, so that the first equipment can establish connection based on the Matter protocol with the second equipment according to the first Internet of things service information which is sent by the second equipment and comprises or indicates the identifier or the name of the Matter protocol.

In some embodiments, the connection based on the Matter protocol may include one of the following: bluetooth connection based on the Matter protocol, wi-Fi connection based on the Matter protocol, thread connection based on the Matter protocol, cellular connection based on the Matter protocol, ethernet connection based on the Matter protocol, other network layer/transport layer protocol connection based on the Matter protocol, etc. The application is not limited to the network layer/transport layer protocol corresponding to the Matter protocol, as long as the connection based on the Matter protocol can be established between the first device and the second device.

The internet of things standard of Matter is an intelligent home connection standard based on internet protocol (Internet Protocol, IP) formulated by the connection standard alliance (Connectivity STANDARDS ALLIANCE, CSA), and solves the problems of compatibility, security, connectivity and the like existing in the intelligent home market. The device Discovery currently adopted by the Matter standard is multicast Domain name system (multicast Domain NAME SYSTEM, MDNS) based device Discovery, which is also called multicast Domain name system/Domain name system service Discovery (DNS SERVICE Discovery, DNS-SD), which is a manner of obtaining Matter devices and service information thereof by means of DNS/DNS-SD query based on a Domain name system.

For example, the data device mDNS record includes data related to the data such as mDNS Service (SRV), pointer (PTR), and text (TXT) record. An SRV record is a resource record that may be used to specify information about services available in a domain. In the SRV record, a name field may be used to indicate identification information of the service, such as the name of the service, a protocol used by the service, such as a universal datagram protocol (User Datagram Protocol, UDP) or a transmission control protocol (Transmission Control Protocol, TCP). PTR records are resource records for pointing to locations in the domain name space. In a PTR record, the RDATA field may be used to store the pointed location. The TXT record may be used to retain descriptive text. In the TXT record, descriptive text may be included in the RDATA field.

The data discovery mechanism needs the internet of things equipment to support IP, the internet of things equipment which does not support IP cannot carry out data discovery, in addition, the data discovery mechanism needs to create and maintain information such as the data related mDNS/DNS-SD SRV, PTR, TXT records and the like, and for the internet of things equipment with low power consumption and limited storage and calculation resources, the possibility exists that the equipment discovery mechanism based on the mDNS/DNS-SD cannot be borne.

In the embodiment of the application, the service information of the Internet of things is indicated through the SDF message, so that the discovery of the Matter equipment can be realized through the SDF message, and the connection between the Matter equipment is further realized.

The embodiment of the application adopts an SDF public message or an SDF subscore message in the SDF message to describe the communication method in the embodiment of the application.

The first device and/or the second device in the embodiment of the present application may be the above-mentioned internet of things device, NAN device or Matter device.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 2 is a flow chart of a communication method according to an embodiment of the present application, where the method may be applied to a first device or a processor of the first device, and the method includes:

S201, a first device receives a release message sent by a second device; the published message includes or indicates first internet of things service information, the published message being a neighbor awareness networking service discovery frame (NAN SDF).

In some embodiments, the first device and/or the second device may be not only found but also found internet of things devices. In the embodiment of the application, the first equipment is used as the found internet of things equipment, and the second equipment is used as the found internet of things equipment for illustration.

In the implementation process, the discovered internet of things devices can broadcast a release message, and the release message broadcast by each discovered internet of things device includes or indicates internet of things service information, which can be internet of things service information supported by each discovered internet of things device.

The publish (Pulish) message in an embodiment of the present application may also be referred to as SDF Pulish quench or NAN SDF Pulish message in other embodiments. The message type of the published message may be a neighbor awareness network service discovery frame (NAN SDF).

In some embodiments, the published message may be sent once within the DW. In other embodiments, the published message may be sent multiple times within the DW. In still other embodiments, the published message may be sent once within multiple DWs. For example, the published message may be sent every other multiple DWs.

The first internet of things service information may include one or more internet of things service information. The first internet of things service information may be service information that the second device may provide to the outside. In some embodiments, the one or more service information included in the first internet of things service information may be all service information that the second device is capable of supporting. For example, in the case where all the service information supported by the second device includes service information 1, service information 2, and service information 3, the one or more service information included in the first internet of things service information may include service information 1, service information 2, and service information 3. In other embodiments, the one or more pieces of service information included in the first internet of things service information may be part of all pieces of service information that the second device is able to support. For example, in the case where all the service information supported by the second device includes service information 1, service information 2, and service information 3, the one or more service information included in the first internet of things service information may include service information 1. The second device may determine to send out service information 1, service information 2, and service information 1 out of service information 3 according to configuration information generated by a user's configuration of the second device or configuration information sent by other devices received. For example, the configuration information may indicate that the service information 1 is outwardly-transmittable information and/or that the service information 2 and the service information 3 are non-outwardly-transmittable information.

In some embodiments, the one internet of things service information may be service information corresponding to an internet of things communication standard. For example, certain service information of the internet of things may include at least one of the following information: service information corresponding to the Matter, service information corresponding to the Bluetooth, service information corresponding to the Wi-Fi, service information corresponding to the zigbee, service information corresponding to the Z-Wave, and service information corresponding to the Cellular. The cell includes a narrowband Internet of things (Narrow Band-Internet of Things, NB-IOT) or a long term evolution Internet of things (LTE-MachinetoMachine, LTE-M). For example, the service information of a certain internet of things may include: the service information corresponding to the Matter and the service information corresponding to the bluetooth, so that a bluetooth connection based on the Matter protocol can be established in case that both the first device and the second device support the Matter and the bluetooth. For another example, the service information of a certain internet of things may include: service information corresponding to the Matter so that a connection based on a Matter protocol can be established in the case that both the first device and the second device support the Matter; the network layer protocol to which the Matter protocol corresponds may be preconfigured.

In other embodiments, one piece of internet of things service information may be service information corresponding to a service type. For example, the service information of a certain internet of things may include one of the following: service information corresponding to temperature monitoring, service information corresponding to humidity monitoring, and the like.

S202, the first device establishes connection with the second device based on the first Internet of things service information.

In some embodiments, where the first internet of things service information includes one internet of things service information, S202 may include: and the first equipment establishes connection with the second equipment under the condition that the first equipment supports the service corresponding to the first Internet of things service information. In this case, the connection established by the first device and the second device may be a connection corresponding to the first internet of things service information. For example, the connection established by the first device with the second device may be a connection based on the Matter protocol, a Wi-Fi connection, a Zigbee connection, or the like. In this way, the first device may transmit Matter information, wi-Fi information, zigbee information, or the like between the second device and the first device. For another example, the connection established by the first device and the second device may be a connection corresponding to temperature monitoring, a connection corresponding to humidity monitoring. In this way, the first device may receive temperature information or humidity information or the like transmitted by the second device.

In other embodiments, where the first internet of things service information includes a plurality of internet of things service information, S202 may include: the first device may determine at least one internet of things service information supported by the first device from the plurality of internet of things service information, and establish a connection with the second device based on the supported at least one internet of things service information. In this case, the connection established by the first device and the second device may be a connection corresponding to at least one internet of things service information. For example, the connection established by the first device with the second device may be a connection based on the Matter protocol and/or a bluetooth connection. Illustratively, the connection that the first device and the second device may establish may be a Wi-Fi connection and/or a bluetooth connection based on the Matter protocol, or the connection that the first device and the second device may establish may be a bluetooth connection based on the Matter protocol. For another example, the connection established by the first device and the second device may be a connection based on a Matter protocol corresponding to the temperature monitoring. In this way, temperature information may be transmitted between the first device and the second device based on the Matter protocol.

In some embodiments, the published message is broadcast by the second device.

The first internet of things service information that the different published messages include or indicate may be different. For example, the second device may determine, based on configuration information generated by a user's setting or configuration information sent by another device, that, in a case where the service that the second device may currently broadcast or propagate outwards increases, decreases, or changes, the first internet of things service information that the release message includes or indicates will also change accordingly. For example, before time t, the first internet of things service information included or indicated by the published message includes service information 1, service information 2, and service information 3. the configuration information is acquired at the time t, and the configuration information indicates that the service information which can be broadcast or spread outwards comprises the service information 1 and the service information 2, or the first internet of things service information which is included or indicated by the release message after the time t comprises the service information 1 and the service information 2 when the configuration information indicates that the broadcast or spread outwards of the service information 3 is stopped.

In some embodiments, before the first device receives the published message sent by the second device, the method further comprises: the first device subscribes to at least one first service; each first service comprises or indicates Internet of things service information; the at least one first service comprises or indicates internet of things service information, and part or all of the first internet of things service information is included. In this way, the first device and the second device both have the service corresponding to part or all of the first internet of things service information, so that the first device and the second device can establish the service connection corresponding to part or all of the first internet of things service information. For example, if some or all of the first internet of things service information includes an identifier or name of the Matter protocol, the first device and the second device may establish a connection based on the Matter protocol.

In some embodiments, the at least one first service includes or indicates internet of things service information, and may include second internet of things service information. In this way, the subscription message broadcast by the first device includes or indicates the second internet of things service information, selected from the at least one first service to which the first device subscribes including or indicating the internet of things service information.

In some embodiments, each of the first services includes or indicates service information of the internet of things, which may be service information corresponding to a communication standard of the internet of things. In other embodiments, each of the first services includes or indicates service information of the internet of things, which may be service information corresponding to a service type.

In some embodiments, the first internet of things service information includes or indicates an identity or name of a Matter protocol.

In this case, the first internet of things service information in the published message broadcast by the second device includes or indicates an identity or name of the Matter protocol, and the first device supports the Matter service, for example, at least one first service subscribed to by the first device includes or indicates the internet of things service information and also includes or indicates the identity or name of the Matter protocol, so that the first device and the second device both support the Matter service, and the first device may establish a connection based on the Matter protocol with the second device. It can be appreciated that if the third device receives the identifier or name of the Zigbee and/or the Matter protocol indicated by the internet of things service information broadcast by the second device, the third device may establish a Zigbee connection with the second device and/or a Zigbee or other network layer protocol connection based on the Matter protocol if the third device also supports the Zigbee and/or Matter service.

In some embodiments, the first internet of things service information includes one or more internet of things service information; each piece of internet of things service information in the one or more pieces of internet of things service information comprises at least one of the following information: the service identifier of the Internet of things and the service name of the Internet of things.

The service identifiers of the internet of things can be in one-to-one correspondence with service names of the internet of things. Thus, different service identifiers of the internet of things can correspond to different service names of the internet of things.
