Description

Technical Field

[0001] This disclosure relates to the field of computer technology, specifically to information synchronization methods, central access node devices, signal extension devices, and computer-readable storage media. Background Technology

[0002] With the development of wireless communication technology, home wireless networks are rapidly becoming more widespread. Currently, due to factors such as signal attenuation and wireless interference, wireless mesh networks have become the preferred network solution for large homes. Wireless mesh networks, through the cooperation of a main AP (Access Point) and Wi-Fi signal extenders, provide wireless coverage anywhere in the user's home. However, current wireless mesh networks require establishing a Wi-Fi WPS-PIN or WPS-PBC connection between the main AP and the Wi-Fi signal extenders. (WPS-PIN stands for Wi-Fi Protected Setup Personal Information Number, a password-required setting in Wi-Fi settings; WPS-PBC stands for Wi-Fi Protected Setup Push Button Configuration, a passwordless setting in Wi-Fi settings.) Configuration information is then synchronized based on this WPS-PIN or WPS-PBC connection. This requires users to operate each Wi-Fi signal extender individually and requires some Wi-Fi background knowledge, making the process cumbersome and inconvenient. Summary of the Invention

[0024] In some embodiments, the peer-to-peer connection is a Wi-Fi peer-to-peer connection.

[0025] In some embodiments, after the step of receiving configuration information sent by the central access node based on the established peer-to-peer connection, the method further includes:

[0026] Disconnect the point-to-point connection from the central access node.

[0027] In some embodiments, after the step of receiving configuration information sent by the central access node based on the established peer-to-peer connection, the method further includes:

[0035] Perform point-to-point scanning;

[0036] The system negotiates point-to-point with the central access node and establishes a point-to-point connection.

[0037] Thirdly, this disclosure also provides a central access node device, comprising:

[0038] One or more first processors;

[0053] To enable those skilled in the art to better understand the technical solutions of the present invention, the information synchronization method, central access node device, signal extension device, and computer-readable storage medium provided by the present invention will be described in detail below with reference to the accompanying drawings.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0055] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0056] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, the singular forms “a” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the said feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded.

[0057] The embodiments described herein can be described with reference to plan views and / or cross-sectional views using the ideal schematic diagrams of this disclosure. Therefore, the example illustrations can be modified according to manufacturing techniques and / or tolerances. Therefore, the embodiments are not limited to those shown in the drawings, but include modifications to configurations formed based on manufacturing processes. Therefore, the areas illustrated in the drawings are schematic in nature, and the shapes of the areas shown in the figures illustrate specific shapes of areas of an element, but are not intended to be limiting.

[0058] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning, unless expressly so defined herein.

[0059] The information synchronization method provided in this disclosure is applicable to wireless mesh network scenarios. Figure 1 This is a schematic diagram of the structure of a Mesh network, such as... Figure 1 As shown, the Mesh network includes a central access node 1 and at least one signal extension device 2. The central access node 1 is used to modify configuration information, that is, users can set and change configuration information on the central access node 1, such as modifying passwords and encryption methods. The signal extension devices 2 are distributed in various locations in the scene and synchronize with the same configuration information to expand the network and ultimately achieve network coverage of the entire scene.

[0060] The information synchronization method provided in this disclosure is particularly suitable for large-sized homes, such as duplexes and villas, in Mesh networking scenarios.

[0061] Figure 2 This is a flowchart of an information synchronization method provided in an embodiment of the present disclosure. The method uses a central access node 1 as the execution entity, such as... Figure 2 As shown, the method includes:

[0062] Step S101: Establish a point-to-point connection with the target signal extension device based on the device information of the target signal extension device.

[0063] The device information of the target signal extension device can be the MAC address of the signal extension device. After obtaining the MAC address of the target signal extension device, the central access node automatically establishes a point-to-point network connection with the target signal extension device to facilitate the subsequent synchronization of configuration information. In practical applications, there are various point-to-point connection methods. This embodiment does not specifically limit the point-to-point connection method.

[0064] Step S102: Based on the established point-to-point connection, the configuration information is sent to the target signal extension device so that the target signal extension device can reconfigure the WIFI according to the configuration information.

[0065] The configuration information sent by the central access node to the target signal extender is the information required to configure the Mesh network. This configuration information may include parameters such as SSID, password, encryption method, and country code. After receiving this configuration information, the target signal extender can subsequently restart its Wi-Fi network to make the received configuration information effective.

[0066] The information synchronization method provided in this disclosure allows the central access node to automatically establish a point-to-point connection with the signal extension device based on the device information of the signal extension device, and to automatically send configuration information to the signal extension device based on the point-to-point connection. This enables the signal extension device to automatically synchronize configuration information with the central access node. Compared with the prior art, the information synchronization method provided in this disclosure reduces the amount of operation required by the user on the signal extension device during the configuration information synchronization process, thereby making the configuration information synchronization process simpler and improving the user experience.

[0067] In some embodiments, the point-to-point connection may be a WIFI point-to-point connection, which is a common working mode of WIFI modules. Compared with other point-to-point connection methods (such as Bluetooth connection), it has a wider transmission bandwidth and a longer transmission distance. Of course, the point-to-point connection method in this disclosure may also adopt other methods, and this disclosure does not make specific limitations.

[0068] Figure 3 A flowchart of another information synchronization method provided in this disclosure embodiment is shown below. Figure 3 As shown, in some embodiments, after step S102, the following step is further included:

[0069] Step S103: Disconnect the point-to-point connection with the target signal extension device.

[0070] In some embodiments, the point-to-point connection can be a one-to-one point-to-point connection. Therefore, when the central access node synchronizes multiple signal extension devices, after synchronizing the configuration information with a certain signal extension device through the point-to-point connection, it needs to disconnect the point-to-point connection with that extension device so that the central access node can subsequently synchronize the configuration information of other signal extension devices.

[0071] Of course, in some embodiments, the point-to-point connection can also be a one-to-many point-to-point connection. In this case, after the central access node completes the synchronization of the configuration information with a certain signal extension device through the point-to-point connection, the step of disconnecting the point-to-point connection with that extension device is not necessary, that is, the above step S103 does not need to be executed.

[0072] In some embodiments, when multiple target signal extension devices need to synchronize configuration information, the method further includes the following before step S101:

[0073] Step S100: Determine the first signal extension device to be synchronized from the pre-configured extension device database as the target signal extension device.

[0074] In this disclosure, the extension device database records device information of multiple signal extension devices to be synchronized and the synchronization order of the multiple signal extension devices to be synchronized. The device information of the signal extension devices includes the MAC address of the signal extension devices. The synchronization order of the signal extension devices to be synchronized refers to the order in which the signal extension devices to be synchronized are synchronized. For example, the extension device database can store the MAC addresses of the signal extension devices to be synchronized in this synchronization order.

[0075] In some embodiments, after step S102, the method further includes:

[0076] Step S104: Determine whether the target signal extension device is the last signal extension device to be synchronized according to the synchronization sequence.

[0077] When it is determined that the target signal extension device is not the last signal extension device to be synchronized, it means that there are still signal extension devices to be synchronized that have not yet had their configuration information synchronized. At this time, the configuration information synchronization should continue, and thus the following step S105 is executed. When it is determined that the target signal extension device is the last signal extension device to be synchronized, it means that all signal extension devices to be synchronized have completed the synchronization of their configuration information. At this time, the configuration information synchronization process can be ended, and the following step S106 is executed.

[0078] Step S105: Select the next signal extension device to be synchronized in the synchronization sequence as the new target signal extension device, and return to continue executing step S101.

[0079] Select a new target signal extension device and return to step S101 to synchronize the configuration information of the new target signal extension device.

[0080] Step S106: Broadcast configuration completion information to all signal extension devices so that the signal extension devices can reconfigure WIFI according to the configuration information in response to the configuration completion information.

[0081] Once all signal extension devices to be synchronized have completed the synchronization of their configuration information, the central access node broadcasts the configuration completion information to the entire network. Upon receiving this configuration completion information, each signal extension device automatically restarts its Wi-Fi to make the received configuration information effective.

[0082] In this embodiment of the disclosure, when multiple signal extension devices need to synchronize their configuration information, the central access node can sequentially establish point-to-point connections with each signal extension device according to a preset synchronization order and synchronize their configuration information. This enables all signal extension devices to automatically synchronize their configuration information, avoiding manual operation by the user and thus improving configuration efficiency and user experience.

[0083] It should be noted that this disclosure does not impose any restrictions on the execution order of steps S103 and S104, as long as both are executed after step S102. Figure 3 Only one execution order is shown and is not intended to limit this disclosure.

[0084] Figure 4 A flowchart of another information synchronization method provided in this disclosure is shown below. Figure 4 As shown, in some embodiments, step S101 may specifically include:

[0085] Step S1011: Broadcast beacon.

[0086] The beacon includes device information of the target signal extender, including the MAC address of the target signal extender. In addition, the beacon also includes point-to-point status information of the central access node, which is used to identify the current point-to-point connection status of the central access node. Furthermore, the point-to-point status information contained in the beacon is in an idle state. When the point-to-point connection status is in an idle state, it indicates that the central access node can currently perform point-to-point connections.

[0087] After receiving the beacon, each signal extender determines whether its own device information is consistent with the device information contained in the beacon. When the device information is consistent, it can be confirmed that it is the target signal extender. At this time, the target signal extender broadcasts a detection request, which includes its own device information.

[0088] Step S1012: Receive the detection request fed back by the target signal extension device.

[0089] The detection request includes device information for the target signal extension device.

[0090] Step S1013: Verify the device information of the target signal extension device in the detection request.

[0091] After receiving the detection request from the target signal extender, the central access node verifies whether the device information contained in the detection request is consistent with the device information of the target signal extender it has identified. If the verification result is consistent, it means that the signal extender broadcasting the detection request is the correct target signal extender, and step S1014 can be executed to start the point-to-point connection process. If the verification fails, the process ends.

[0092] Step S1014: Broadcast point-to-point connection startup information.

[0093] After verifying the authenticity of the target signal extender, the central access node broadcasts a point-to-point connection initiation message. Upon receiving this message, the target signal extender performs a point-to-point scan to establish a point-to-point connection.

[0094] Step S1015: Conduct point-to-point negotiation with the target signal extension device and establish a point-to-point connection.

[0095] After the target signal extender finishes scanning, the central access node negotiates point-to-point with the target signal extender and establishes a point-to-point connection.

[0096] This disclosure also provides an information synchronization method, applied to the signal extension device side, such as... Figure 5 As shown, the method includes:

[0097] Step S201: Establish a point-to-point connection with the central access node.

[0098] Step S202: Based on the established point-to-point connection, receive the configuration information sent by the central access node. The configuration information is used for subsequent WIFI reconfiguration.

[0099] Steps S201 and S202 correspond to steps S101 and S102 in the above embodiments, respectively. Please refer to the description of steps S101 and S102 for details, which will not be repeated here.

[0100] The information synchronization method provided in this disclosure allows the signal extension device to automatically establish a point-to-point connection with the central access node and automatically obtain configuration information from the central access node based on this point-to-point connection. This enables the signal extension device to automatically synchronize configuration information with the central access node. Compared with the prior art, the information synchronization method provided in this disclosure reduces the amount of operation required by the user on the signal extension device during the configuration information synchronization process, thereby making the configuration information synchronization process simpler and improving the user experience.

[0101] In some embodiments, the point-to-point connection is a WIFI point-to-point connection, which is a common working mode of WIFI modules. Compared with other point-to-point connection methods (such as Bluetooth connection), it has the advantages of wider transmission bandwidth and longer transmission distance.

[0102] Figure 6 Another information synchronization method provided in the embodiments of this disclosure, such as Figure 6 As shown, in some embodiments, after step S202, the following steps are further included:

[0103] Step S203: Disconnect the point-to-point connection with the central access node.

[0104] Step S203 corresponds to step S103 in the above embodiment, and will not be repeated here. Please refer to the description of step S103 for details.

[0105] In some embodiments, after step S202, the method further includes:

[0106] Step S204: Receive the configuration completion information broadcast by the central access node.

[0107] Step S205: In response to the configuration completion information, reconfigure the WIFI according to the configuration information.

[0108] Steps S204 and S205 correspond to step S106 in the above embodiment, and will not be repeated here. Please refer to the description of step S106 for details.

[0109] In some embodiments, step S201 specifically includes:

[0110] Step S2011: Receive the beacon broadcast by the central access node.

[0111] The beacon includes device information for the target signal extender, which includes the MAC address of the target signal extender.

[0112] Step S2012: Determine whether you are a target signal extender based on the device information of the target signal extender contained in the beacon.

[0113] If it is determined that it is a target signal extension device, then step S2023 is executed; if it is determined that it is not a target signal extension device, then a broadcast is performed.

[0114] Step S2013: Broadcast a detection request, which includes the device's own information;

[0115] Step S2014: Receive the point-to-point connection start information broadcast by the central access node.

[0116] Step S2015: Perform point-to-point scanning.

[0117] Step S2016: Conduct point-to-point negotiation with the central access node and establish a point-to-point connection.

[0118] In this embodiment of the disclosure, steps S2011 to S2026 correspond to steps S1011 to S1015 in the above embodiment. Please refer to the description of steps S1011 to S1015 for details, which will not be repeated here.

Then, click "One-click Networking" on the extension management page of the operable interface to start this process. During the process, a progress bar will prompt the user. After the network synchronization is completed, the user will be prompted that "Synchronization Complete".

[0124] If a user purchases and adds an expansion device separately, an input field needs to be added to the expansion management interface of the operable interface. The user will be prompted to enter the MAC address on the expansion device label. After the user clicks "Save", network synchronization will begin. During the network setup process, a progress bar and the corresponding device being synchronized will be displayed. Once synchronization is complete, the user will be prompted that "Synchronization Complete".

They can also set timed on / off functions and manage the configuration of individual extended devices in certain scenarios.

If the target signal extender is not the last signal extender to be synchronized, the next signal extender to be synchronized in the synchronization order is taken as the new target signal extender, and the process of establishing a point-to-point connection with the target signal extender based on its device information continues. Based on the device information of the target signal extender contained in the beacon, determine whether it is the target signal extender; When it determines that it is the target signal extension device, it broadcasts a detection request, which includes its own device information; Establish a point-to-point connection with the central access node; Based on the established point-to-point connection, the configuration information sent by the central access node is received. The configuration information is used for subsequent WIFI reconfiguration. In response to receiving the configuration completion information broadcast by the central access node, WIFI reconfiguration is performed according to the configuration information; wherein, the configuration completion information is broadcast by the central access node to all signal extension devices when it determines that the target signal extension device is the last signal extension device to be synchronized.
