Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, and in particular to an automatic relay method and device, a storage medium and a WiFi relay device. BACKGROUND

[0002] In today's increasingly popular wireless local area network (WLAN) technology, the wireless access point (AP) as an important part of the network infrastructure, plays a bridge role in connecting wireless stations (STA) and wired networks or other wireless networks. However, in the actual deployment and application process, the performance of the AP and the communication quality between the AP and the STA are often affected by various factors.

[0003] One of the significant problems is that due to the physical obstruction of the AP or its own small transmission power, the signal coverage range is limited, so that some STAs in certain locations cannot establish stable and reliable connections with the AP. This not only affects the data transmission efficiency and quality between the STA and the AP, but also may further hinder the data transmission between different STAs communicating through the AP, seriously affecting the overall performance and user experience of the wireless network.

[0004] In order to solve the above problems, a common method in the prior art is to introduce a relay device. The relay device can receive wireless signals from the AP or the STA, amplify them and then forward them to the target device, thereby effectively expanding the coverage of the wireless network, enhancing the signal strength and improving the communication quality. However, to realize this function of the relay device, a series of complex network parameter configurations are required, including but not limited to operating frequency band, channel selection, encryption method, network authentication information, etc.

[0005] Currently, these network parameter configurations are mostly completed manually by the user, and the user is required to have certain professional knowledge and operating skills of wireless networks. This is undoubtedly a great challenge for ordinary users, not only increasing the operation difficulty and complexity, but also possibly causing the relay device to malfunction due to improper configuration, and even causing interference or security risks to the entire wireless network.

[0006] Therefore, how to simplify the configuration process of the relay device, reduce the requirement for professional knowledge of the user, and at the same time ensure that the relay device can stably and efficiently realize its function of expanding the network coverage range and enhancing the signal strength, has become a technical problem to be solved in the current wireless local area network technology field.

[0036] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0037] Reference Figure 1 , Figure 1 is a network architecture diagram of a wireless fidelity communication system. The wireless fidelity communication system includes a wireless station 10, a WiFi relay device 11, a WiFi relay device 13, a wireless access point 12 and a wireless station 14. The above-mentioned devices communicate with each other through wireless WiFi protocol

[0038] The WiFi relay device 11 and the WiFi relay device 13 have the functions of both STA and AP, and the WiFi relay device of a non-root node can be connected to one or more subordinate WiFi relay devices or to a STA.

[0039] In the embodiments of the present application, the wireless station can be a smartphone, a tablet computer, a game device, an AR (Augmented Reality) device, a car, a data storage device, an audio playback device, a video playback device, a notebook computer, a desktop computing device, etc.

[0040] The embodiments of the present application will be described below in conjunction with the accompanying drawings. Figure 2 The automatic relay method provided by the embodiments of the present application will be described in detail. The automatic relay method in the embodiments of the present application can be a method for automatically determining whether a WiFi relay device is a root node or a non-root node. Figure 1 The station in the embodiments of the present application can be a WiFi relay device.

[0041] Please refer to Figure 2 The flowchart of the automatic relay method provided by the embodiments of the present application is shown in FIG. 1. The method provided by the present application can include the following steps:

[0042] S201, after the first WiFi relay device is powered on, the STA function and the AP function are started simultaneously, and the relay deep value is initialized to 0.

[0043] After the first WiFi relay device is powered on, the first WiFi relay device first performs initialization operations at the hardware and software levels. The hardware initialization can include checking network interfaces (wired and wireless), power status, etc.; the software initialization involves loading the operating system, the driver program, and the WiFi relay related application program.

[0044] After the initialization is completed, the device starts the STA function and the AP function simultaneously. The STA function allows the device to scan and attempt to connect to the surrounding WiFi network as a client, while the AP function enables the device to provide a WiFi signal for other devices to connect as a hotspot. The start of these two functions usually involves configuring network interface parameters (such as SSID, password), starting network listening services, etc.

[0045] In addition, the device also initializes an internal variable named "relay deep" to 0. This variable is used to identify the hierarchical position of the device in the entire WiFi relay network. A relay deep value of 0 indicates that the device has not been connected to any superior relay device or wired network and is an independent node.

[0046] S202, the first WiFi relay device detects whether it is connected to a wired network through a network cable.

[0047] Wherein, the device detects wired network connection by checking the physical connection status of the network interface and attempting to communicate through a wired network protocol (such as Ethernet). The physical connection status can be obtained by reading the status register of the network interface, while the communication attempt can involve sending and receiving test packets.

[0048] If the device detects that a wired network connection exists and is stable, it will proceed to the next operation S203; otherwise, it will perform S204 to attempt a wireless connection.

[0049] Further, the first WiFi relay device detects the physical connection status by reading the status register of the network interface (such as the Ethernet interface). These status registers usually contain information about the connection status of the network interface, such as whether the link is established, the connection speed, the duplex mode, etc. Or the first WiFi relay device can also detect whether the network cable is connected and the connection is stable by detecting physical layer signals (such as voltage, current, etc.). For example, the Ethernet interface will detect a specific voltage change when the connection is established, thereby confirming the existence of the physical connection.

[0050] S203, if yes, update the relay depth value of the first WiFi relay device to 1, and broadcast the relay information of the first WiFi relay device through Beacon Frame and Probe Response Frame, the relay information including the relay depth value and the network quality parameter value; the WiFi relay device with relay depth value equal to 1 is the root node.

[0051] Wherein, once the device detects a wired network connection, the following operations will be performed:

[0052] Update the relay depth value to 1, indicating that the device is now the root node (i.e. the starting point of the entire relay network).

[0053] Generate a relay information packet containing the relay depth value and the network quality parameter value (such as signal strength, link delay, etc.). These parameters can be obtained through network diagnostic tools or protocols.

[0054] Broadcast its relay information through Beacon Frame and Probe Response Frame. Beacon Frame is sent periodically to inform surrounding devices of the existence of the hotspot; Probe Response Frame is sent when the device receives Probe Request Frame.

[0055] S204, if no, scanning the surrounding AP to get the AP list, selecting an AP with the best network quality in the AP list to connect; after successfully connecting to the selected AP, updating the relay depth value of the first WiFi relay device to 1; or the first WiFi relay device scans the surrounding WiFi relay device to get the relay device list; selecting a superior WiFi relay device with a relay depth value greater than 0 and the best network quality in the relay device list, and sending a connection request frame carrying the relay information of the first WiFi relay device to the superior WiFi relay device; when the first WiFi relay device receives the connection permission frame returned by the superior WiFi relay device based on the connection request frame, the first WiFi relay device updates its relay depth value to the relay depth value of the superior WiFi relay device + 1; and sending the relay information of the first WiFi relay device to the outside through the beacon frame and the scan response frame.

[0056] If the device does not detect a wired network connection, one of the following steps will be performed to attempt a wireless connection:

[0057] 1. Scan and connect to the optimal AP:

[0058] The device starts the wireless scanning function, scans the surrounding APs and generates an AP list.

[0059] Sort the AP list according to network quality parameters (such as signal strength, stability, whether it supports the required security protocol, etc.).

[0060] Select an optimal AP and try to connect using the configured SSID and password.

[0061] If the connection is successful, the device updates the relay depth value to 1 and prepares to broadcast its relay information (if configured to allow relay).

[0062] 2. Scan and connect to the optimal superior relay device:

[0063] If the device is configured to support relay-to-relay connection, it will start the wireless scanning function, scan the surrounding WiFi relay devices and generate a relay device list.

[0064] Sort the relay device list according to the relay depth value and network quality parameters. Note that in order to avoid forming a relay link loop, the device may select a relay device with a relay depth value greater than 0 and not its own as the superior relay.

[0065] Select an optimal superior relay device and send a connection request frame carrying its own relay information to it. The connection request frame may contain the device's SSID, password (if required by the superior relay), relay depth value, network quality parameters, etc.

[0066] Wait for the response of the superior relay device. If a connection permission frame is received, the device updates its relay depth value to the relay depth value of the superior relay device plus 1, and starts broadcasting its relay information (if configured to allow relay).

[0067] For example: The first WiFi relay device does not detect a wired network connection, so it starts scanning for APs and relay devices around it. It finds two APs (AP1 and AP2) and one relay device (Relay-A). According to the signal strength and stability, it chooses to connect to AP1 (signal strength -65dBm, high stability). After a successful connection, it updates the relay depth value to 1 and prepares to broadcast its relay information.

[0068] In another case, if the first WiFi relay device is configured to support relay-to-relay connection, and finds that Relay-A is a better choice (relay depth value 1, signal strength -60dBm), it will send a connection request frame to Relay-A. After receiving the connection permission frame from Relay-A, it updates its relay depth value to 2 (the relay depth value of Relay-A plus 1), and starts broadcasting its relay information.

[0069] S205, the first WiFi relay device receives a connection request frame from the second WiFi relay device, the connection request frame carrying the relay information of the second WiFi relay device.

[0070] Among them, as an AP or relay device, the first WiFi relay device can receive connection request frames from other WiFi relay devices (such as the second WiFi relay device). These request frames usually contain the SSID, password (if applicable), relay depth value, network quality parameters, etc. of the relay device requesting connection.

[0071] The device first verifies the legitimacy of the connection request frame (such as checking whether the SSID and password match). If it is legitimate, it will proceed to the next step; otherwise, it will ignore the request frame.

[0072] S206, after parsing the received connection request frame, the relay information of the second WiFi relay device is obtained, and whether to allow the access of the second WiFi relay device is judged according to the network quality parameters in the parsed relay information. If yes, a connection permission frame is sent to the second WiFi relay device, so that the second WiFi relay device updates its relay depth value to the relay depth value of the first WiFi relay device plus 1 based on the received connection permission frame.

[0073] Wherein, the device parses the received connection request frame, obtaining the relay information of the second WiFi relay device (including the relay depth value and network quality parameters, etc.). Then, it decides whether to allow the second WiFi relay device to access according to these information and its own configuration and network state.

[0074] The decision process may involve the following factors:

[0075] Relay depth limit: The device may be configured with a maximum relay depth value. If the relay depth value of the second WiFi relay device plus its own relay depth value exceeds this limit, the device will reject the access request.

[0076] Network quality: The device may evaluate the feasibility of the connection according to the network quality parameters of the second WiFi relay device (such as signal strength, stability, etc.). If the network quality is poor, the device may reject the access request or require the second WiFi relay device to adjust its transmission power or position.

[0077] Avoiding loopback: The device needs to check whether the second WiFi relay device is already its subordinate device or whether it will cause a relay link loopback. If so, the device will reject the access request.

[0078] If the device decides to allow access, it will send a connection permission frame to the second WiFi relay device, which may contain some additional configuration information (such as specified channel, transmission power, etc.). At the same time, it instructs the second WiFi relay device to update its relay depth value to the device's relay depth value plus 1.

[0079] Wherein, the first WiFi relay device needs to periodically detect the connection status with the upper-level relay device or wired network. This can be achieved by sending heartbeat packets, monitoring network interface status, or checking routing tables, etc.

[0080] If the device detects that the connection is disconnected (i.e. broken), it will perform the following operations: reset its own relay depth value to 0, indicating that it is no longer a relay node. Disconnect all subordinate relay WiFi devices. This can be achieved by sending a disconnect instruction or stopping broadcasting relay information. Note that in order to avoid affecting the connection of STAs, the device may need to first notify the subordinate relay devices that they need to handle the disconnection operation themselves. Keep all STA connections unchanged. This means that the device will continue to serve as an AP for STAs even if it is no longer a relay node.

[0081] It should be noted that the first WiFi relay device can try to re-establish the connection with the upper-level relay device or wired network. If successful, it will update the relay depth value and restore the relay function.

[0082] In summary, the beneficial effects of implementing the embodiments of the present application include:

[0083] Automatic relay configuration and deployment: After the relay device is powered on, it automatically starts the STA and AP functions, and intelligently selects the working mode according to whether it is connected to a wired network through a network cable. If connected to a wired network, it broadcasts its relay information as a root node (relay depth value is 1); if there is no network cable connection, it automatically scans and connects to the optimal AP or upper relay device, and automatically updates the relay depth value according to the connection situation. This process does not require manual configuration by the user, greatly simplifying the deployment process of the relay device.

[0084] Dynamic network quality evaluation and selection: When selecting a connected AP or upper relay device, the relay device makes the optimal selection based on network quality parameters (such as signal strength, delay, etc.), ensuring the stability and efficiency of the relay link. At the same time, when receiving a connection request from a lower relay device, the relay device also determines whether to allow access based on network quality parameters, further ensuring the performance of the entire relay network.

[0085] Avoidance of relay loop and broken line processing: The technical solution designs a broken line detection mechanism. When the relay device detects a broken line, it resets the relay depth value and disconnects all lower relay devices, but maintains the connection of the STA, effectively avoiding the formation of a relay loop and ensuring that the basic network connection of the STA is not affected.

[0086] Extensibility and flexibility: The technical solution allows hierarchical connection of relay devices, and each relay device can automatically adjust its role (root node, intermediate node or leaf node) according to the current network environment. This dynamic adjustment mechanism makes the relay network have good extensibility and flexibility, and can adapt to wireless network environments of different scales and complexities.
