Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a device network distribution method, apparatus, electronic device, storage medium and computer product. Background Technology
[0002] With the rapid development of communication technology and the widespread adoption of home Internet of Things (IoT) devices, connecting smart devices to the network has become the foundation of whole-house intelligence. Currently, smart devices can be configured for network access via a bootstrap hotspot, a process known as seamless configuration. A bootstrap hotspot is a hidden hotspot emitted by a home Wireless Fidelity (Wi-Fi) router or gateway after power-on initialization. Users bind this router or gateway using an application (APP). Once the device is powered on, it scans for and connects to this bootstrap hotspot to initiate a network access request. After verifying the device's legitimacy, the platform sends Wi-Fi hotspot information to the device. Upon receiving the Service Set Identifier (SSID) and password, the device connects to this hotspot to complete the device binding and network connection.
[0003] However, the method of configuring the network by guiding hotspot channels requires one scan and two hotspot connections during the entire configuration process. Furthermore, the devices access the network as STA nodes using a complete 7-layer Open Systems Interconnection (OSI) model. The configuration process requires starting services such as CoAP, MQTT, and HTTP, resulting in high power consumption during current device configuration. Here, STA (Station) refers to a terminal device connected to a wireless network in a wireless LAN. CoAP (Constrained Application Protocol) is a World Wide Web-like protocol in the Internet of Things (IoT) world. MQTT (Message Queuing Telemetry Transport) is a standards-based message passing protocol. HTTP (HyperText Transfer Protocol) is a protocol used for distributed, collaborative, hypermedia information systems. Summary of the Invention

This allows for the construction of broadcast data packets using the proprietary format, once the target channel of the network management device with the strongest received signal strength within a preset range is identified, and broadcast on the target channel. The target network management device can then be identified from the network management devices that respond to the broadcast data packet.

[0031] Step 140: Configure the network based on the target protocol and the device address of the target network management device.
[0032] It should be noted that the device network configuration method provided in this application embodiment can be executed by a smart device, which may include, but is not limited to, IoT smart devices such as cameras, robot vacuums, speakers, body fat scales, etc.
[0033] The smart device of this application can be equipped with or connected to a device distribution network device, thereby controlling the device distribution network device to execute the device distribution network method of this application.
[0034] In this application, the 7-layer OSI model can be simplified beforehand. Specifically, the network layer, transport layer, session layer, and presentation layer can be removed from the 7-layer OSI model, retaining the physical layer, data link layer, and application layer. Furthermore, the retained physical layer, data link layer, and application layer are reused to obtain a simplified 802.11 Wi-Fi protocol (which can also be referred to as a minimalist protocol in this application) as the target protocol.
[0035] The physical layer defines physical characteristics, such as 0 and 1 electrical signals; the data link layer includes device drivers in the operating system and corresponding network interfaces, and has functions such as establishing, maintaining, tearing down, frame packaging, transmission, synchronization and error recovery of data links; the application layer is responsible for establishing and managing the network topology, maintaining communication paths between devices, security management, control and reporting functions.
[0036] Furthermore, the data link layer of the simplified protocol in this application reuses the data link layer in the OSI model, but adjusts the data packet format according to the specific requirements of the simplified protocol to formulate a private data packet format, so that the application layer can receive and send private data through Wi-Fi management frames.
[0037] Figure 2 This is a schematic diagram of the privatized data packet format in the device network configuration method provided in this application embodiment, such as... Figure 2 As shown, the format of the link layer frame data in this application is as follows: 2-bit (Byte) Frame Control field, 2-bit Duration field, 6-bit Destination MAC (Media Access Control) address, 6-bit Source MAC address, 6-bit Basic Service Set Identifier (BSSID), 2-bit Sequence Number (Seq), n-bit Frame Body, and 4-bit Frame Check Sequence (FCS).
[0038] The message element in the frame body contains the following: ID (1 Byte): Identifier used to indicate the type of message element.
[0039] Len (1 Byte): Length, indicating the length of the Value field in this message element, i.e. how many bytes of data the Value field contains.
[0040] OUI (3 Bytes): Organizationally Unique Identifier, used to identify a manufacturer or organization.
[0041] Value (n Byte): This is the actual data carried in the message element, and its content and format depend on the type specified by the ID field.
[0042] Furthermore, in the management frame message body, the Value field of message element ID 221 is filled with communication data of the simplified protocol, and the Magic Num field in the data format is fixed. In this way, communication data can be sent and received through the link layer management frame.
[0043] Specifically, the Value can include: Magic Num (4 Bytes): a magic number used to identify the start and format of the datagram.
[0044] Source (6 Bytes): The source MAC address, which is the same as the source address in the link layer frame format.
[0045] Destination (6 Bytes): Destination MAC address, which is the same as the destination address in the link layer frame format.
[0046] Type (1 Byte): Type or service number, which may be used to distinguish different services or protocols.

[0053] Length (2 Byte): Length, indicating the length of the data portion.
[0054] Data (n Byte): Data, the actual data content transmitted.
[0055] The content of data in a Data application can include: Type (2 Bytes): Type, indicating the type or protocol of the data.
[0056] Len (1 Byte): Length, indicating the length of the data in this field.
[0057] Value (n Byte): The value, the actual data content.
[0058] Furthermore, the aforementioned simplified protocol and the established proprietary data packet format can be configured into smart devices, enabling all data interactions between smart devices and network management devices such as routers / gateways to be transmitted using Probe Request frames throughout the entire network configuration and management process. A Probe Request frame is a management frame in Wi-Fi networks, primarily used by devices during active scanning to broadcast the SSID of the wireless network they wish to connect to.
[0059] Understandably, the smart devices that require network distribution in this application can be referred to as devices to be distributed.
[0060] Therefore, after the device is powered on and initialized for the first time, it can enable STA mode. STA mode, short for Station mode, is the working mode in a Wi-Fi network where the device acts as a client connecting to an existing wireless network. In STA mode, the device can receive wireless signals from other devices or routers and access the network or other network resources through that wireless network.
[0061] Furthermore, the device to be configured on the network can scan for hotspot information emitted by network management devices such as routers or gateways within a preset range (specifically, a range where signals can be received). Based on the received signal strength indication in each hotspot information, the channel where the network management device with the highest received signal strength indication is located is determined as the target channel.
[0062] Furthermore, disable STA mode and enable Monitor promiscuous mode. Monitor mode is a special operating mode that allows the device to listen to all data packets passing through its wireless interface, regardless of whether these packets are intended for the device. This mode is typically used for network analysis and troubleshooting because it captures all traffic on the network, including non-broadcast and non-multicast packets. Promiscuous mode is a network monitoring mode that allows the device to capture and analyze all data packets passing through the wireless network, regardless of whether these packets are intended for the device. In promiscuous mode, the device can receive all data packets sent by other devices, including broadcast and multicast packets.
[0063] Disabling STA mode and enabling Monitor promiscuous mode means that the device will no longer connect to the wireless network as a client, but will instead become a listener that can capture all data packets passing through its wireless interface.
[0064] Furthermore, the device to be distributed can construct broadcast data packets using a proprietary data packet format and broadcast them single-channel in the target channel via a data link layer management frame, with a preset broadcast period. After the broadcast ends, obtain the Received Signal Strength Indication (RSSI) values from all broadcast responses within the threshold range. Response messages from candidate network management devices within the scope.
[0065] Furthermore, the device to be distributed can determine its distance from each candidate network management device based on its information receiving sensitivity and the corresponding transmit power and receive signal strength indications of each candidate network management device.
[0066] The target network management device is further determined from among the candidate network management devices based on the distance between them.
[0067] Furthermore, the device to be configured can initiate a network access request to the target network management device through a simplified protocol based on the device address of the target network management device, and complete the network configuration after the target network management device determines that the device to be configured has passed the verification based on the network access request.
[0068] According to the device network configuration method of this application embodiment, a target protocol is obtained by hierarchically simplifying and reusing the Open Systems Interconnection (OSI) model. A private data packet format is then formulated based on the target protocol. After determining the target channel where the network management device with the highest received signal strength indication within a preset range is located, a broadcast data packet can be constructed using the private data packet format and broadcast on the target channel. This allows the target network management device to be identified from network management devices that return response packets based on the broadcast data packet. Therefore, network configuration can be performed based on the target protocol and the device address of the target network management device. By simplifying the OSI model, the network configuration process does not require the initiation of services such as CoAP, MQTT, and HTTP, thus reducing service power consumption. Furthermore, the private data packet format formulated based on the target protocol enables communication technology based on link-layer management frames, allowing devices to communicate based on device addresses, significantly reducing the amount of data transmitted and lowering transmission power consumption. Therefore, device network configuration power consumption can be reduced.
[0069] In addition, this application adopts a three-layer simplified Wi-Fi protocol for communication, which has the security of data transmission. Besides reducing the power consumption of communication transmission, it also shortens the network configuration time and improves the success rate and reliability of correct device binding.
[0070] Based on the above embodiments, determining the target channel where the network management device with the highest received signal strength indication within a preset range is located includes: Scan for hotspot information emitted by network management devices within a preset range; The receiving signal strength indicator with the largest value among the receiving signal strength indicators corresponding to each hotspot information is determined as the target receiving signal strength indicator; The channel where the network management device corresponding to the target received signal strength indicator is located is determined as the target channel.
[0071] Specifically, in this application, the device to be configured on the network can scan for hotspot information with the service set identifier "CMCC-GUIDE-LINK" issued by network management devices such as routers / gateways within a preset range of the surrounding environment, with a preset scanning period. After the scan is completed, the receiver signal strength indicator with the highest RSSI value (i.e., the strongest signal) in each hotspot information is identified as the target receiver signal strength indicator. The channel of the router / mesh corresponding to the target receiver signal strength indicator is then determined as the target channel, i.e., the optimal channel. Simultaneously record the optimal RSSI value. .
[0072] This application selects the optimal channel based on the received signal strength indication, which can reduce interference with other wireless devices. It can then construct broadcast data packets using a proprietary data packet format and broadcast the broadcast data packets on the target channel. This allows the target network management device to be identified from the network management devices that return response packets based on the broadcast data packets. As a result, network allocation can be performed based on the target protocol and the device address of the target network management device, which helps to improve the accuracy of network allocation.
[0073] Based on the above embodiments, determining the target network management device from network management devices that return response messages based on broadcast data packets includes: Based on the received signal strength indication of each network management device that returns response messages based on broadcast data packets, candidate network management devices are determined from the network management devices that return response messages based on broadcast data packets; Obtain the transmit power of each candidate network management device from its response message; Based on the information receiving sensitivity and the corresponding transmit power and receive signal strength indications of each candidate network management device, the distance to the corresponding candidate network management device is determined. The target network management device is determined from among the candidate network management devices based on the distance between them.
[0074] Specifically, in this application, the device to be configured in the network can obtain the received signal strength indication when each network management device returns a response message based on a broadcast data message, and set the received signal strength indication at a threshold. Network management devices within the specified range are identified as candidate network management devices. Here, R is a value set according to actual needs, for example, it could be -10.
[0075] Meanwhile, the device to be distributed can obtain its sensitivity to receiving information, which is known after the device is initialized.
[0076] In this application, the device to be configured on the network can parse the received response message, extract the value of the PowerTx field of the private data packet format from the response message, and obtain the transmission power of the corresponding network management device, which is the transmission power of the transmission source (router / gateway).
[0077] Furthermore, based on the information receiving sensitivity and the corresponding transmit power and receive signal strength indications of each candidate network management device, combined with the location estimation algorithm, the distance to the corresponding candidate network management device can be determined.
[0078] Furthermore, based on the distance, one device can be selected from the candidate network management devices as the target network management device.
[0079] This application uses information such as the true RSSI value, transmit power, and receive sensitivity of different routers / gateways under optimal channel conditions, and employs an RSSI model-based location estimation algorithm to calculate the distance of the scanned router / gateway devices within a single period, thereby determining the target network management device. It fully considers the impact of spatial environment and multipath effects of wireless signal transmission, accurately obtains the distance between the device to be configured and the router / gateway, improves the reliability of the scanning and connection phases, and reduces the probability of the device to be configured being mistakenly bound to a neighbor's device.
[0080] Based on the above embodiments, when determining the distance to the corresponding candidate network management device based on the information receiving sensitivity and the corresponding transmit power and received signal strength indication of each candidate network management device, the following operations are performed for each candidate network management device: Add the transmit power of the current candidate network management device to the first constant to obtain the first result; Subtracting the first result from the information receiving sensitivity yields the second result; Subtract the second result from the received signal strength indication of the current candidate network management device to obtain the third result; The third result is compared with the fourth result to obtain the fifth result; the fourth result is the product of the preset threshold and the second constant. The preset power value of the fifth result is determined as the distance to the current candidate network management device.
[0081] Specifically, when determining the distance to a candidate network management device based on information receiving sensitivity and the corresponding transmit power and received signal strength indication for each candidate network management device, this application calculates the distance for each candidate network management device using the following expression based on the RSSI model position estimation algorithm: ; in, The known quantity is the received packet. , refers to the actual value of the signal strength indicator of the broadcast response received by the device in the distribution network after it sends a message via broadcast; To determine the transmission power of the transmitter, the register value of the PowerTx field in the data format is extracted after parsing the broadcast response message; The receiving sensitivity of the device to be distributed to the network is known after the device is initialized; is the distance between the device to be networked and the router / gateway; n is a constant, the path attenuation factor for wireless signal transmission, whose value varies due to multipath effects, temperature, humidity, light, etc., and is usually taken as . In the experiment, 2.5 was used; It is an environmental impact factor and is a constant.
[0082] Based on this, the distance to each candidate network management device can be determined separately.
[0083] This application uses information such as the true RSSI value, transmit power, and receive sensitivity of different routers / gateways under optimal channel conditions, and employs an RSSI model-based location estimation algorithm to calculate the distance of the scanned router / gateway devices within a single period, thereby determining the target network management device. It fully considers the impact of spatial environment and multipath effects of wireless signal transmission, accurately obtains the distance between the device to be configured and the router / gateway, improves the reliability of the scanning and connection phases, and reduces the probability of the device to be configured being mistakenly bound to a neighbor's device.
[0084] Based on the above embodiments, determining the target network management device from among the candidate network management devices based on the distance to each candidate network management device includes: The distance with the smallest value among the distances to each candidate network management device is determined as the target distance; The candidate network management device corresponding to the target distance is identified as the target network management device.
[0085] Specifically, in this application, the device to be configured in the network can determine the minimum distance among the distances between itself and each candidate network management device as the target distance, i.e., the shortest distance. Furthermore, the candidate network management device corresponding to the target distance is determined as the target network management device (i.e., the locally optimal router / gateway).
[0086] This application identifies the candidate network management device with the shortest distance as the target network management device. Since the closer the distance, the stronger the signal strength is usually, it helps to improve the stability of the network connection and the reliability of data transmission. In addition, close-range connection can reduce interference from other wireless devices or obstacles to the signal, thereby reducing the error rate in the data transmission process and improving the success rate of network distribution. Furthermore, for wireless devices, close-range communication can reduce transmission power, thereby reducing energy consumption.
[0087] Based on the above embodiments, network configuration is performed based on the target protocol and the device address of the target network management device, including: Based on the target protocol, a network access request is initiated to the target network management device using the device address of the target network management device; Receive the network access notification returned by the target network management device based on the network access request.
[0088] Specifically, the device to be configured in this application can obtain the device address (e.g., MAC address) corresponding to the target network management device, i.e., the optimal router / gateway.
[0089] Furthermore, a network access request can be initiated to the target network management device using the obtained device address via the target protocol (i.e., the simplified protocol).
[0090] Specifically, the device address of the target network management device can be filled into the message body of the simplified protocol, thereby initiating a network access request to the target network management device and receiving a network access notification returned by the target network management device based on the network access request.
[0091] After receiving a network access request, the target network management device verifies the legality of the device based on the information in the request. Once it confirms that the device to be configured has passed the legality verification, it notifies the device to complete the network access. At the same time, as the parent device of the device to be configured, it reports the attribute information of the device to the server platform for registration. After registration is completed, a data connection link is established, thereby completing the device configuration and going online. This enables the device to be configured to be identified and managed on the server platform, and realizes functions such as remote control.
[0092] In this application, communication between devices is based on MAC addressing, which greatly reduces the amount of data transmitted and lowers the power consumption. Furthermore, communication between devices based on MAC addressing also improves the efficiency and speed of data transmission, thereby shortening the network distribution time.
[0093] Figure 3 This is a schematic diagram of the overall process of the device network configuration method provided in the embodiments of this application, such as... Figure 3 As shown, after the process begins and the device to be configured is powered on and initialized, this application can determine whether it has been configured before. If so, it enters the simplified protocol data interaction process; otherwise, it enables STA mode and scans for hotspot information with the first service set identifier "CMCC-GUIDE-LINK" issued by the router / gateway, with a preset scanning cycle. After the scan is completed, the channel where the router with the strongest RSSI in the environment is located is determined, i.e., the optimal channel. Simultaneously record the optimal RSSI value. .
[0094] Furthermore, disable STA mode and enable Monitor promiscuous mode.
[0095] Furthermore, a broadcast data message is constructed and transmitted via a data link layer management frame (i.e., a Probe Request frame) on the optimal channel. Perform single-channel broadcasting with a preset broadcast period. After the broadcast ends, obtain the RSSI values of all broadcast responses within the threshold. Broadcast response messages within range (in the experiment) The received broadcast response message is parsed, and the value of the PowerTx field in the data format is extracted, which is the transmission power of the transmitting source (router / gateway).
[0096] Furthermore, based on the RSSI model, the location estimation algorithm is used to solve for the wireless signal transmission distance (i.e., the distance between the device to be configured and the router / gateway) obtained from the broadcast response.
[0097] Obtain the MAC address information of the router / gateway corresponding to the shortest distance as the optimal router / gateway information under the optimal channel.
[0098] Furthermore, the optimal router / gateway information is filled into the simplified protocol message body of the Probe Request frame to initiate a network access request.
[0099] Receive network access request notification information, connect to the server, complete network configuration and binding, and end the process.
[0100] This application requires no additional hardware. Building upon existing smart device network configuration solutions, it only requires modification of the Wi-Fi protocol driver layer, making it more compatible with low-power, resource-constrained devices. Furthermore, by employing a location estimation algorithm based on the RSSI model, it simplifies the user's network configuration process while improving the success rate of correctly associating devices with users in complex network environments, reducing the mis-binding rate. Compared to ordinary network configuration solutions, it offers greater reliability and stability, while also shortening configuration time and enhancing the user experience, thus contributing to the development of whole-house smart home solutions.

[0104] The device network distribution apparatus of this application simplifies the Open Systems Interconnection (OSI) model hierarchically and then reuses it to obtain the target protocol. Based on the target protocol, a proprietary data message format is formulated. This allows the network management device, after determining the target channel where the network management device with the highest received signal strength within a preset range is located, to construct a broadcast data message using the proprietary data message format and broadcast it on the target channel. The target network management device can then be identified from the network management devices that return response messages based on the broadcast data message. Thus, network distribution can be performed based on the target protocol and the device address of the target network management device. By simplifying the OSI model, the network distribution process does not require the initiation of services such as CoAP, MQTT, and HTTP, reducing service power consumption. Furthermore, the proprietary data message format based on the target protocol enables communication technology based on link-layer management frames, allowing devices to communicate based on device addresses, significantly reducing the amount of data transmitted and lowering transmission power consumption. Therefore, the device network distribution power consumption can be reduced.

The preset power value of the fifth result is determined as the distance to the current candidate network management device.
[0108] In one embodiment, the second determining module includes a second determining unit, the second determining unit being used for: The distance with the smallest value among the distances to each candidate network management device is determined as the target distance; The candidate network management device corresponding to the target distance is determined as the target network management device.
