[0058] To make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the specific technical solutions of the embodiments of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0059] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0060] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0062] The present invention provides a device interaction method, as shown in FIG1A , including:

[0063] Step S110: In response to the first device being in the external device scanning phase, obtaining a first network protocol detection frame sent by a third device, wherein the first network protocol detection frame carries second information of at least one second device;

[0064] Here, the first device can be any type of terminal device with external device scanning capabilities. The external device scanning phase involves real-time, automatically triggered device scanning by the first device, with a very high frequency of location-triggered scanning. The third device can be capable of periodically broadcasting a first network protocol probe frame, or sending a probe response frame to the first device in response to a probe request frame sent by the first device during the external device scanning phase. The first network protocol can be a protocol that enables the third device to broadcast probe frames or send probe response frames.

[0065] The first network protocol may be a wireless communication protocol, i.e., a protocol used for inter-device communication in a wireless communication environment, responsible for networking and communication between devices within the network, such as Wireless Fidelity (WIFI), IPv6 Ethernet (6Ethernet), Radio Frequency Identification (RFID), Near Field Communication (NFC), Zigbee, IPv6 Low-Speed ​​Wireless Version (6LoWPAN), Global System for Mobile Communications (GSM), General Packet Radio Service (GPS), Bluetooth (BT), 3G, 4G, 5G, etc. These protocols can ensure the security and reliability of data transmitted on the network.

[0066] For example, the first network protocol may be a WIFI network protocol, the third device may be a WIFI routing device, and the first device and the second device may be terminal devices that can connect to the WIFI routing device. Here, the WIFI driver can be automatically loaded when the first device is turned on, and the WIFI driver is always active, even if the WIFI function is turned off. It is the most basic capability of electronic devices and does not incur additional overhead. Since the coverage of WIFI routers and WIFI is much greater than that of BT or NFC, electronic devices connected to the cluster router can achieve fast connections across floors, buildings, and the entire campus.

[0067] In some embodiments, the first network protocol detection frame may be a detection frame of a WIFI MAC. Figure 1B is a MAC frame structure provided in an embodiment of the present application. As shown in Figure 1B, the frame header (MAC Header) of the MAC frame includes a Frame Control. Figure 1C is a structural diagram of a Frame Control provided in an embodiment of the present application. As shown in Figure 1C, the Frame Control includes a Type byte and a Subtype byte. Figure 1D is a table of Type bytes and Subtype bytes provided in an embodiment of the present application. As shown in Figure 1D, the table includes a Beacon frame, a Probe Request frame, and a Probe Response frame.

[0068] Here, beacon frames, probe request frames and probe response frames are management frames of WIFI MAC, which can be sent and received regardless of whether a router is connected. Among them, Beacon frame and Probe Request are broadcast frames, Probe Response is a unicast frame, and the data in the frame body is filled by Element. Figure 1E is a structural diagram of an Element provided in an embodiment of the present application, and Figure 1F is an Element ID filling table provided in an embodiment of the present application. As shown in Figure 1F, some Element IDs are reserved (Reserved), that is, they have not been used. During the implementation process, these IDs can be used, or the customizable field of Vendor Specific 221 can be used directly to carry the second information. Figure 1G is a schematic diagram of the frame structure of Vendor Specific 221 provided in an embodiment of the present application. As shown in Figure 1G, the Vendor Specific 221 includes an element ID (Element ID), length (Length), organization identifier (Organization Identifier) ​​and vendor-specific content (Vender-specific content). Figure 1H is a schematic diagram of the Vendor Specific 221 frame filling content provided in an embodiment of the present application. As shown in Figure 1H , the code (Number) is Vendor Specific 221, the length (Length) is 7, and the vendor identifier (OUI) is 00:0C:43, which is the vendor code. The vendor filling content includes Type (Type): 7 and Data (Data): 07000000. During implementation, users can fill in the OUI, Type, and Data fields with the second information as needed.

[0069] Beacon frames, Probe Request frames, and Probe Response frames all contain one or more Element IDs 221, Vendor Specific. Currently, most devices use independent Wi-Fi scanning, independent of the Wi-Fi switch. This allows the Vendor Specific field to be used to discover the desired device and share information before connecting, without requiring any additional effort.

[0070] During implementation, the first device can automatically trigger a device scan in real time. Each time the first device triggers an external device scan, it can obtain a first network protocol detection frame sent by the third device to update the surrounding connectable devices (the second device). Here, the discovery and information sharing of the second device is almost real-time because the first device's automatic scanning and positioning triggering scan frequency is very high, which is equivalent to updating the surrounding connectable devices with each scan.

[0071] Step S120: parsing the first network protocol detection frame to obtain second connection information included in the second information for establishing a connection with an external device;

[0072] Here, the second connection information includes at least one of the following: a service set identifier (SSID) of the connection, a local area network address of a wireless access point, a device tag, an application identifier of the connection, a device name, and an attribute feature of the device.

[0073] The attribute characteristics of the device include at least one of the following: screen size, resolution, audio codec, video codec and transmission rate.

[0074] In some embodiments, the second connection information also includes a Basic Service Set Identifier (BSSID). For example, a company is relatively large and has installed several wireless access points (APs) or wireless routers. Company employees only need to know one SSID to access the wireless network anywhere within the company. The BSSID can be the MAC address of each wireless access point. When employees move within the company, the SSID remains unchanged. However, the BSSID changes continuously as you switch to different wireless access points.

[0075] In some embodiments, the second connection information further includes a TCP / UDP port, wherein the TCP protocol is the Transmission Control Protocol (TCP), and the UDP protocol is the User Datagram Protocol (UDP), both of which belong to the transport layer protocol.

[0076] During implementation, the first device may parse the first network protocol detection frame to obtain at least one of the above second connection information. For example, the first device may obtain the service set identifier of the connection of the second device, the local area network address of the wireless access point, and the device name.

[0077] Step S130: Determine that the first device requests to connect to the second device, and establish a connection with the second device based on the second connection information.

[0078] For example, the first device may establish a connection based on the second connection information when the first device requests to establish a WIFI point-to-point (WIFIp2p), BT, or NFC connection with the second device.

[0079] In an embodiment of the present application, first, in response to the first device being in the external device scanning phase, a first network protocol detection frame sent by a third device is obtained, wherein the first network protocol detection frame carries the second information of at least one second device; then, the first network protocol detection frame is parsed to obtain the second connection information included in the second information for establishing a connection with the external device; finally, it is determined that the first device requests to connect to the second device, and a connection is established with the second device based on the second connection information. In this way, the first device can obtain the second information during the external device scanning phase, so that when requesting to connect to the second device, it can quickly and accurately connect to the second device without the need for a preliminary negotiation process, thereby effectively improving the connection efficiency between devices. Both one-to-one and one-to-many connections are equally efficient, and have great advantages in the Internet of Things (IOT) scenario where everything is connected.

[0080] In some embodiments, the above step S110 “obtaining the first network protocol detection frame sent by the third device in response to the first device being in the external device scanning phase” can be implemented by one of the following steps:

[0081] Step 111: In response to the probe request frame sent by the first device during the external device scanning phase, the first device receives the probe response frame of the third device as the first network protocol probe frame;

[0082] During the implementation process, during the external device scanning phase, the first device sends a probe request frame to the third device, and the third device sends a probe response frame to the first device in response to the acquired probe request frame. The probe response frame may include the device information of other devices acquired by the third device. For example, during the WIFI scanning phase, the terminal as the first device may send a Probe Request frame to the routing device as the third device. After receiving the Probe Request frame, the routing device returns a Probe Response frame to the terminal. The Probe Response frame may carry information about other connected terminals scanned by the routing device. In some embodiments, the information about the other connected terminals may be stored in a preset information table in the routing device. The information table may be updated in real time based on changes in the terminal connected to the routing device. In this way, the terminal device can obtain the latest information table in real time.

[0083] or,

[0084] Step 112: During the external device scanning phase, the first device listens for and receives a beacon frame broadcasted by the third device as the first network protocol detection frame.

[0085] During the implementation process, the third device can send a beacon frame by broadcasting at a fixed time, and the first device listens to the broadcast to obtain a first network protocol frame. For example, in the WIFI scanning phase, the routing device as the third device sends a Beacon frame by broadcasting, and the terminal as the first device can receive the Beacon frame. The Beacon frame can carry the information of the connection terminal scanned by the routing device, wherein the connection terminal can be the first device and the second device, that is, the first device and the second device are both devices connected to the third device, and their positions in the network can be equivalent. In some embodiments, the information of the connection terminal can be stored in a preset information table in the routing device. The information table can be updated in real time based on changes in the terminal connected to the routing device. In this way, the terminal devices (the first device and the second device) can obtain the latest information table in real time.

[0086] In this embodiment of the present application, in response to a probe request frame sent by the first device during the external device scanning phase, the first device receives a probe response frame from the third device as the first network protocol probe frame; or, in the external device scanning phase, the first device intercepts and receives a beacon frame broadcast and sent by the third device as the first network protocol probe frame. In this way, the first device can obtain the probe response frame or the beacon frame as the first network protocol probe frame.

[0087] In some embodiments, before the step 111 in which "the first device receives the probe response frame of the third device as the first network protocol probe frame", the following steps are also included:

[0088] Step 113: The first device is in the external device scanning phase, and in response to the first device sending a probe request frame to the third device, wherein the probe request frame carries first information of the first device, and the first information includes first connection information for establishing a connection with the external device.

[0089] During implementation, the first device is equivalent to the second device, that is, the first device and / or the second device both send a probe request frame to the third device during the external device scanning phase, wherein the probe request frame sent by the first device carries the first information, and the probe request frame sent by the second device carries the second information. The third device can obtain the device information of any device that sends a probe request frame to it. For example, a routing device, as the third device, can obtain the terminal information of any terminal that sends a probe request frame to it during the external device scanning phase, and the terminal information includes connection information of the terminal establishing a connection with other terminals, and the connection can be a BT connection or an NFC connection.

[0090] In the embodiment of the present application, the first device is in the external device scanning phase, and in response to the first device sending a probe request frame to the third device, the third device can receive the device information of the device that sent the probe request frame to it.

[0091] In some embodiments, as shown in FIG2 , in step 113 above, “in response to the first device being in the external device scanning phase, the first device sending a probe request frame to the third device” may be implemented by the following steps:

[0092] Step S210: The first device uses a target application to obtain first attribute information of the first device, where the first attribute information is used for device grouping.

[0093] Here, the target application may be an application provided in the first device or the second device, and the target application may be used to obtain the first attribute information of the first device or the second attribute information of the second device.

[0094] The first attribute information includes at least one of the following information: connection capability, location information, and an identifier set by the user. During implementation, the first attribute information can be used to group devices. For example, based on the connection capability, devices can be divided into a group with BT connection capability and a group with NFC connection capability; based on the location information, devices within the same location range can be divided into the same group, and the location range can be the same room, the same building, or the same work park; based on the identifier set by the user, devices with the same identifier can be divided into the same group, and users can set the same identifier for the devices they manage to divide the devices they manage into the same group.

[0095] Step S220: add the first attribute information of the first device to the first information and send the first information to the third device, so that the third device groups the first device and the second device based on the first information and the second information including the second attribute information of the second device to obtain a target device group belonging to the same attribute.

[0096] During implementation, the target application may be used to add the first attribute information to the first information and send the first information to the third device, so that the third device can group the first device and the second device based on the first attribute information and the second attribute information.

[0097] In some embodiments, when the third device broadcasts a Beacon frame or returns a Probe Response frame to the first device or the second device, it only sends or returns information about devices with a target application identifier. This allows electronic devices that have the target application configured to efficiently obtain information about electronic devices that have also configured the target application, thereby improving connection efficiency.

[0098] In an embodiment of the present application, the first device uses a target application to obtain first attribute information of the first device, and the first attribute information is used for device grouping. The first attribute information of the first device is added to the first information, so that the third device groups the first and second devices based on the first information and second information including the second attribute information of the second device, thereby obtaining a target group of devices with the same attribute. In this way, by setting a target application on the first device to obtain the first attribute information for device grouping, the third device can group the first and second devices, and then send information after grouping, which can effectively improve connection efficiency.

[0099] In some embodiments, the above step S110 “obtaining the first network protocol detection frame sent by the third device in response to the first device being in the external device scanning phase” can be implemented by the following process:

[0100] In response to the first device being in the external device scanning phase, second connection information of at least one second device belonging to the same target device group as the first device and sent by the third device is obtained.

[0101] During implementation, since the third device can group the second device and the first device based on the second attribute information and the first attribute, when the third device sends the first network protocol detection frame to the first device, it can send the second connection information of at least one second device that belongs to the same target device group as the first device. For example, based on the connection capability, the third device divides the devices into a group with BT connection capability and a group with NFC connection capability, and then can send the second connection information of the second device that also has BT connection capability as the first device to the first device; the third device can divide the devices within the same location range into the same group based on location information, and the location range can be the same room, the same building, or the same work park, and then can send the second connection information of the second device that belongs to the same room as the first device to the first device; the third device can divide the devices with the same identifier into the same group based on the identifier set by the user. The user can set the same identifier for the devices under his / her management to divide the devices under his / her management into the same group, and then the third device can send the second connection information of the second device with the same identifier as the first device to the first device.

[0102] In this embodiment of the present application, during the external device scanning phase, the first device receives second connection information from the third device for at least one second device belonging to the same target device group as the first device. Thus, by sending device information belonging to the same group to the first device, the first device can efficiently connect to the desired device.

[0103] In conjunction with the description of the content executed by the third device, the device interaction method provided in the embodiment of the present application includes:

[0104] During the external device scanning phase, the third device receives a probe request frame sent by the second device. The probe request frame carries second information about the second device, including second connection information for establishing a connection with the external device. The third device then adds the second connection information to a beacon frame and broadcasts it, allowing the first device to obtain the second connection information. Alternatively, in response to the probe request frame sent by the first device, the third device adds the second connection information to a probe response frame and sends it to the first device. The first device's subsequent processing can refer to the description of the corresponding portion of the above embodiment.

[0105] In some embodiments, during the external device scanning phase, a third device receives a probe request frame sent by the first device. The probe request frame carries first information of the first device, wherein the first information includes first connection information and first attribute information, and the second information includes second connection information and second attribute information. The first attribute information and the second attribute information are used for device grouping. The third device groups all first and second devices based on the first and second attribute information to obtain a target group of devices with the same attributes. The third device then adds the second connection information of the same group as the first device to a beacon frame for broadcast or to a probe response frame sent to the first device. The first device's subsequent processing may refer to the description of the corresponding section above.

[0106] An embodiment of the present application provides a first device, which is capable of connecting to a third device. As shown in FIG3A , the first device includes:

[0107] The first receiving device 301 is configured to obtain, in response to the first device being in an external device scanning phase, a first network protocol detection frame sent by the third device, wherein the first network protocol detection frame carries second information of at least one second device;

[0108] The first processing means 302 is configured to parse the first network protocol detection frame and obtain second connection information included in the second information for establishing a connection with an external device;

[0109] The first connecting means 303 is configured to determine that the first device requests to connect to the second device, and to establish a connection with the second device based on the second connection information.

[0110] In an embodiment of the present application, first, the first receiving device responds to the first device being in the external device scanning phase, and obtains the first network protocol detection frame sent by the third device, wherein the first network protocol detection frame carries the second information of at least one second device; then the first processing device parses the first network protocol detection frame, and obtains the second connection information included in the second information for establishing a connection with the external device; finally, the first connection device determines that the first device requests to connect to the second device, and establishes a connection with the second device based on the second connection information. In this way, the first device can obtain the second information during the external device scanning phase, so that when requesting to connect to the second device, it can quickly and accurately connect to the second device without the need for a preliminary negotiation process, thereby effectively improving the connection efficiency between devices. Both one-to-one and one-to-many connections are equally efficient, and have great advantages in the scenario of interconnecting everything in the Internet of Things.
