Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a WiFi connection method, a router, and a storage medium. Background Art

[0002] WiFi (Wireless Fidelity) is based on wireless communication technology to connect electronic devices such as computers to a network through a wireless access point. When the password of the shared WiFi network is changed by the device user, all devices that have already connected to the WiFi network need to use the updated password to reconnect to the WiFi network.

[0003] In the prior art, when a single device encounters a wrong WiFi password, the device only automatically disconnects, and does not provide a clear password error prompt until the user himself / herself notices the network interruption and enters the device for settings. The user's setting process is generally as follows: find the list of connected networks, manually select and delete the WiFi network with the wrong password, and then the user needs to re-search for the WiFi network and enter the new password to re-establish the connection.

[0004] The current technical solutions require the user to perform multiple confirmations and operations, and cannot completely automatically retrieve the new password and reconnect. The user has more operation steps, reducing the user experience. Summary of the Invention

[0005] The present invention provides a WiFi connection method, a router, and a storage medium, which can monitor the WiFi network status in real time and respond quickly after the WiFi password is modified, simplify the network connection recovery steps, and improve the user experience.

[0006] According to one aspect of the present invention, there is provided a WiFi connection method, which is cooperatively executed by a connecting device and a router, including:

[0007] Through the connecting device, when it is determined that the connection to the target WiFi network is disconnected, a first request is generated and sent to the router providing the target WiFi network;

[0008] Through the router, according to the first request and a pre-established device connection information table, a password update notification is sent to the connecting device;

[0009] Through the connecting device, after receiving the password update notification, in response to the user's password acquisition operation, a second request is generated and sent to the router;

[0010] Through the router, when it is determined that the connecting device is an authorized device according to the second request and the device connection information table, an encrypted password is sent to the connecting device;

[0011] Reconnect to the WiFi network via the connection device according to the encrypted password.

[0012] According to another aspect of the present invention, there is provided a router, which includes:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can execute the WiFi connection method described in any embodiment of the present invention.

[0016] According to another aspect of the present invention, there is provided a computer-readable storage medium storing computer instructions for causing a processor to implement the WiFi connection method described in any embodiment of the present invention when executed.

[0017] In the technical solution of the embodiment of the present invention, by using a connection device, when it is determined that the connection to the target WiFi network is disconnected, a first request is generated and sent to the router providing the target WiFi network. Using the router, according to the first request and the device connection information table, a password update notification is sent to the connection device. Using the connection device, after receiving the password update notification, in response to the user's password acquisition operation, a second request is generated and sent to the router. Using the router, when it is determined that the connection device is an authorized device, an encrypted password is sent to the connection device. Using the connection device, according to the encrypted password, the way to reconnect to the WiFi network enables the connection device to automatically start the processing flow after the WiFi password is modified, without the need for the user to perform a manual reconnection operation. The connection device system can monitor the WiFi network status in real time. Once it detects that the password is modified, it can quickly start the processing flow and timely reconnect the device to the network, reducing the impact of network interruption on the user and improving the user experience. Moreover, it can prevent unauthorized devices from obtaining the new password, effectively enhancing the security of the network.

[0025] Embodiment 1

[0026] Figure 1 is a flowchart of a WiFi connection method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where after the password of the target WiFi network is updated, the connecting device automatically obtains the new password and reconnects. This method can be executed in cooperation by the connecting device and the router, and the connecting device and the router have data processing functions. As Figure 1 shown, this method includes:

[0027] S110. When it is determined that the connection to the target WiFi network is disconnected through the connection device, a first request is generated and sent to the router providing the target WiFi network.

[0028] Optionally, the present invention is designed based on the OpenHarmony system. The connection device can be various electronic devices installed with the OpenHarmony system and having a wireless connection function, capable of communicating with the WiFi network, including but not limited to mobile phones, smart communication devices, computers, in-vehicle devices, smart home devices, etc.

[0029] Optionally, in the prior art, a router can be used to create and manage a WiFi network, provide network access services for connection devices. The router connects multiple connection devices together through wireless signals and connects these devices to the Internet or other networks to achieve data forwarding and sharing. In this application, the router refers to the router providing the target WiFi network. However, only for explaining the WiFi reconnection process through this router, the WiFi connection method of the present invention is applicable to other routers and is not limited thereto.

[0030] Optionally, the connection device and the router are within the coverage range of the same frequency band of the WiFi signal and both support the standard protocols of WiFi communication, such as IEEE 802.11b / g / n / ac and other protocols.

[0031] Optionally, the connection device can subscribe to the network status change event notification in advance. When it is detected that the connection status of the connection device to the target WiFi network changes from connected to disconnected, the connection device will receive the network disconnection event notification. The connection device will obtain the network handle and the callback function. According to the network handle, the identifier of the currently disconnected target WiFi network can be determined, and then the router receiving the first request can be determined. The callback function can be used to generate the first request according to the preset logic.

[0032] The advantage of such a setting is that the connection device system can monitor the WiFi network status in real time. Once it detects that the password is modified, it can quickly start the processing flow and timely reconnect the device to the network, reducing the impact of network interruption on users.

[0033] Optionally, the first request includes the device identifier of the connection device, the router identifier, and the password acquisition request identifier. The device identifier may include the MAC (Media Access Control) address and IMEI (International Mobile Equipment Identity) code of the device, or may only include the MAC address; the router identifier may refer to the SSID (Service Set Identifier) of the router, that is, the name of the target WiFi network; the password acquisition request identifier is a preset request type identifier, and the identifier content can be customized. For example, "0x01" is used to represent the request for obtaining the password. The password acquisition request is used to request the password from the router. When sending the first request, the connection device does not know that the target WiFi has updated the password. The first request is only a password acquisition request sent for reconnecting to the target WiFi, and does not specify to obtain the updated password.

[0034] S120. Through the router, according to the first request and the pre-established device connection information table, send a password update notification to the connection device.

[0035] Wherein, the device connection information table may include the device identifiers, connection statuses, and authorization identifiers of the connection devices connected to the target WiFi network.

[0036] Wherein, the method may further include any one of the following:

[0037] Through the router, whenever it is determined that a new device is connected to the target WiFi network, determine the device identifier of the new device according to the network protocol, and store the device identifier of the new device in the device connection information table maintained by the router;

[0038] Through the router, real-time monitor the connection statuses of the connection devices in the device connection information table, and in the device connection information table, store the connection statuses of the connection devices corresponding to the device identifiers of the connection devices respectively; and

[0039] Through the router, when receiving a permission change request sent by the router management program, determine the device identifier of the target connection device for which the permission is being changed according to the permission change request, and in the device connection information table, modify the authorization identifier corresponding to the device identifier of the target connection device.

[0040] Optionally, whenever a new device successfully connects to the target WiFi network provided by the router, the router obtains the device's MAC address and IMEI code (if the device supports providing the IMEI code) through the network protocol, marks the status as "connected", changes the status to "not connected" after disconnection, and stores the device's MAC address, IMEI code, and connection status in the device connection information table maintained in the router's storage database. The storage format can be to record the information of one device per line, separating the MAC address, IMEI code, and connection status with a specific delimiter (such as a comma). When the connection status of the device is updated, read the device connection information table, find the corresponding device information line, modify the connection status field, and then write it back to the device connection information table.

[0041] Optionally, the user can find the connected device and perform authorization settings through the user management interface of the application. The application is an application for network management. The application can send a permission change request to the router using the HTTP protocol. The permission change request can be a POST request, encapsulating the device information of the connected device for which the permission is changed in JSON format in the request body. The permission change request also includes authorization or cancellation of authorization information. The router parses the permission change request and records the authorization information in the is_authorized field of the device corresponding to the MAC address in the device information table.

[0042] Optionally, the device identifier of the connected device in the device connection information table can include only the MAC address, or can also include the MAC address and IMEI code; the connection status includes connected and not connected; the authorization identifier can be represented by different identifier values, respectively indicating authorized and unauthorized. For example, it can be represented by 0 for unauthorized and 1 for authorized.

[0043] Optionally, the router can determine whether there is a data row with this device identifier recorded in the device connection information table based on the device identifier and the device connection information table. If it exists, it is determined that the connected device is a device that has historically connected to the target WiFi network. If the request type identifier in the first request is recognized as obtaining the password 0x01, that is, the first request includes a password acquisition request, the router can send a password modification notification message to the connected device through the TCP protocol.

[0044] Optionally, on the connected device side, a TCP server is pre-started to listen on a specified port to receive notification messages from the router.

[0045] S130: Through the connected device, after receiving the password update notification, in response to the user's password acquisition operation, generate a second request and send it to the router.

[0046] Optionally, after receiving the password update notification through the connection device, in response to a user's password acquisition operation, and generating a second request to be sent to the router, it may include:

[0047] After receiving the password update notification through the connection device, generating a password update prompt box and presenting it to the user; wherein, the password update prompt box includes password update inquiry information and operation options;

[0048] When the connection device responds to a user's password acquisition operation, generating a second request to be sent to the router; wherein, the second request includes a request for obtaining a new password and the device identifier of the connection device.

[0049] Optionally, the password update notification is a message sent by the router through the TCP protocol, which may be in the form of a data packet, and the password update notification is used to notify the connection device that the password of the router has been changed.

[0050] Optionally, the password update prompt box may contain password update inquiry information, which is in text form, and the password update inquiry information may be used to ask the user whether they wish to obtain a new password; the operation options may include an OK option and a Cancel option.

[0051] Optionally, when the user clicks the OK option through the connection device, it is determined that the user's password acquisition operation is responded to; when the user clicks the Cancel option through the connection device, reconnecting to the target WiFi network is cancelled.

[0052] Optionally, the request for obtaining a new password in the second request is used to obtain the updated password.

[0053] S140. When the router determines that the connection device is an authorized device according to the second request and the device connection information table, sending an encrypted password to the connection device.

[0054] Optionally, after receiving the second request sent by the connection device, the router parses the MAC address of the device from the second request, queries the authorization identifier corresponding to the MAC address in the device connection information table through an SQL query statement, and determines whether the device is authorized to obtain the password.

[0055] Optionally, when it is determined that the connection device is an authorized device, the new password is encrypted by the AES (Advanced Encryption Standard) algorithm and sent to the connection device.

[0056] The advantage of such a setting is that by using the unique identification information of the device for device identification, it is ensured that only authorized connected devices can interact with the router, thereby preventing unauthorized devices from obtaining the new password and effectively improving the network security.

[0057] S150. Reconnect to the WiFi network according to the encrypted password by connecting the device.

[0058] Optionally, after receiving the encrypted password by connecting the device, use the same key and AES algorithm for decryption. The decryption result is the updated new password. Use the new password to reconnect to the target WiFi network and store the new password.

[0059] The technical solution of the embodiment of the present invention, by using the connected device, when it is determined that the connection to the target WiFi network is disconnected, generates a first request and sends it to the router providing the target WiFi network. Using the router, according to the first request and the device connection information table, sends a password update notification to the connected device. Using the connected device, after receiving the password update notification, in response to the user's password acquisition operation, generates a second request and sends it to the router. Using the router, when it is determined that the connected device is an authorized device, sends the encrypted password to the connected device. Using the connected device, according to the encrypted password, reconnects to the WiFi network. In this way, after the WiFi password is modified, the connected device can automatically start the processing flow without the user performing a manual reconnection operation. The connected device system can monitor the WiFi network status in real time. Once it detects that the password is modified, it can quickly start the processing flow and timely reconnect the device to the network, reducing the impact of network interruption on the user and improving the user experience. Moreover, it can prevent unauthorized devices from obtaining the new password and effectively improve the network security.

[0060] Embodiment 2

[0061] Figure 2 The flowchart of a WiFi connection method provided for the second embodiment of the present invention. Based on the above embodiment, this embodiment specifically describes the WiFi connection method. As Figure 2 shown, the method includes:

[0062] S210. When the connected device receives a network disconnection event notification, determine the currently disconnected target WiFi network according to the network handle and call the callback function to generate a first request.

[0063] Wherein, the first request includes the device identifier of the connected device, the router identifier, and the password acquisition request identifier.

[0064] Wherein, the connected device subscribes to the network status change event notification in advance by calling the target method in the OpenHarmony system.

[0065] Optionally, in the OpenHarmony system, the subscribeNetworkStateChanged method in the ohos.net.NetManager class can be called to subscribe to network state change event notifications. This method requires two parameters to be passed in. The first parameter is of the NetHandle type and can be obtained through ohos.net.NetManager.getNetHandle(), which represents the network handle. The second parameter is a callback function of the NetStateCallback type, which is used to handle network state change events.

[0066] Optionally, the ohos.net.NetManager.getNetHandle() method can return a valid network handle based on the current network connection status of the system. The network handle can be used to identify an object of a specific network connection. In the OpenHarmony system, a device may be connected to multiple different types of networks simultaneously, and each network connection has a unique NetHandle corresponding to it. Through the network handle, the system can accurately identify and manage different network connections.

[0067] Optionally, a callback function of the NetStateCallback type can be used to handle network state change events. When the network state changes, the system will call the callback function and pass the relevant network state information to the callback function. The connected device can implement the preset processing logic in the callback function. That is, after determining that the network state has changed from the connected state to the disconnected state, a first request is generated.

[0068] S220: Through the router, determine the device identifier of the connected device according to the first request, and when it is determined that the device identifier of the connected device is already stored in the device connection information table, send a password update notification to the connected device.

[0069] Optionally, through the router, determine the device identifier of the connected device according to the first request, and when it is determined that the device identifier of the connected device is not stored in the device connection information table, the first request is ignored.

[0070] S230: Through the connected device, after receiving the password update notification, generate a password update prompt box and display it to the user.

[0071] Among them, the password update prompt box includes password update inquiry information and operation options.

[0072] S240: Through the connected device, when responding to the user's password acquisition operation, generate a second request and send it to the router.

[0073] Among them, the second request includes a request for obtaining a new password and the device identifier of the connected device.

[0074] Optionally, a method for displaying a dialog box is pre-created in the AbilitySlice component of OpenHarmony on the device, and a Dialog object is created in this method. The basic properties of the Dialog object are pre-set, and the basic properties may include the custom layout, text information, OK button, and cancel button of the password update prompt box. The text information is used to ask the user whether they wish to obtain a new password. In addition, the processing logic of the OK button and the cancel button in the Dialog object is included in this method. After receiving the password update notification, the Dialog object is called to display the password update prompt box to the user. After the user clicks the OK or cancel button, the corresponding operation is executed according to the logic corresponding to the button. The logic corresponding to the OK button is to generate a second request and send it to the router in response to the user's password acquisition operation. The logic corresponding to the cancel button is to cancel the password update and close the password update prompt box.

[0075] S250: Through the router, determine the device identifier of the connected device according to the second request, and obtain the authorization identifier of the connected device according to the device connection information table and the device identifier of the connected device.

[0076] In an optional example, the router can query the authorization identifier corresponding to the MAC address through an SQL statement. For example, the SQL statement for finding the device with the MAC address '00:11:22:33:44:55' and checking the authorization status can be: SELECT * FROM device_info WHERE mac_address = '00:11:22:33:44:55' AND is_authorized = '1'.

[0077] S260: Through the router, when it is determined that the connected device is an authorized device according to the authorization identifier, encrypt the updated new password and send it to the connected device.

[0078] Optionally, through the router, when it is determined that the connected device is an unauthorized device according to the authorization identifier, send an unauthorized notification to the connected device.

[0079] S270: Through the connected device, decrypt the encrypted password and determine the new password of the target WiFi network according to the decryption result.

[0080] S280: Through the connected device, reconnect to the target WiFi network using the new password and store the new password.

[0081] Optionally, after the connected device obtains the decrypted new password, it can call the API (Application Programming Interface) related to WiFi connection in the OpenHarmony system, such as the method in the ohos.net.wifi.WifiManager class, to automatically connect to the WiFi network.

[0082] In the technical solution of the embodiment of the present invention, by using the connected device, when it is determined that the connection to the target WiFi network is disconnected, a first request is generated and sent to the router providing the target WiFi network. The router, according to the first request and the device connection information table, sends a password update notification to the connected device. The connected device, after receiving the password update notification, in response to the user's password acquisition operation, generates a second request and sends it to the router. When the router determines that the connected device is an authorized device, it sends the encrypted password to the connected device. The connected device reconnects to the WiFi network according to the encrypted password. In this way, after the WiFi password is modified, the connected device can automatically start the processing flow without the user having to perform a manual reconnection operation. The connected device system can monitor the WiFi network status in real time. Once it detects that the password has been modified, it can quickly start the processing flow and promptly reconnect the device to the network, reducing the impact of network interruption on the user and improving the user experience. Moreover, it can prevent unauthorized devices from obtaining the new password, effectively enhancing the security of the network.
