Detailed ways

The Internet of Things (IoT), which can be understood as "the Internet where everything is connected", is an extended and expanded network based on the Internet. It is a huge network formed by combining various information sensing devices with the network. Realize the interconnection of people, machines and things at any time and any place.

Smart home is the basic application of the Internet of Things in the home. With the popularization of broadband services, smart products involve all aspects of users' lives. FIG. 1 is a schematic diagram of a smart home scene provided by an embodiment of the present application. Referring to FIG. 1 , the scene includes a routing device, a home hub device, at least one electronic device, and devices used by a user. The home hub device and at least one electronic device can be connected to the routing device to establish a network connection.

Wherein, the routing device may be a device having a routing function, such as a router. The electronic device may be a smart home device, such as an IoT device such as a smart doorbell, a smart door lock, a refrigerator, a washing machine, a smart speaker, and a smart TV. The home hub device can integrate home business services to control at least one electronic device in a smart home scene. The home hub device may be a long-term power device that is resident in the home, such as smart speakers, smart TVs, smart routing devices, set-top boxes, and other devices.

In the scenario shown in FIG. 1 , an IoT application can be installed on a device used by a user, and at least one electronic device can be bound to a user account in the IoT application. The user can operate the IoT application to configure the network for at least one electronic device. When the electronic device is bound to the user account and the network configuration is completed, the user can view information such as the status of the electronic device in the IoT application, and the user can control it through the IoT application. Electronic equipment. For example, after the smart speaker is bound to the user account and the network configuration is completed, the user can view the status of the smart speaker as "online" in the IoT application, and the user can click the shortcut command entry in the IoT application, and the device used by the user responds Based on the operation triggered by the user, control instructions are sent to the smart speaker, such as controlling the smart speaker to play music.

The IoT application installed on the device used by the user can be the client of the IoT application. Many electronic equipment manufacturers or IoT solution providers also provide smart home server platforms or IoT cloud servers. The information of the electronic devices bound to the user account is acquired on the application client, so as to perform data analysis and management on multiple electronic devices.

In some scenarios, the IoT application can synchronize information such as device identification and authentication credentials of at least one electronic device bound to the user account to the home hub device. Wherein, the authentication credential of the electronic device is information obtained by the IoT application for establishing a secure session with the electronic device. After the home hub device receives information such as the device identification and authentication credentials of at least one electronic device, it can be considered that the home hub device is associated with at least one electronic device. At this time, at least one electronic device can connect to the IoT application or IoT cloud server through the home hub device agent , so as to achieve unified control, unified data analysis, and cross-device intelligent linkage and other services through converging and connecting to the home central equipment. Optionally, the home hub device can be used as a control device to control the operation of at least one electronic device, and can also be controlled by an IoT application as a controlled device.

The smart home scene shown in Figure 1 can be realized in two ways: pre-installation and post-installation. The post-installation means that the user first decorates the house, and then purchases electronic equipment by himself and binds it to his user account; IoT solution providers cooperate with real estate companies to complete the installation and commissioning of electronic equipment during the decoration stage of real estate projects delivered to final residents. After users move in, they can directly bind electronic equipment to their user accounts.

Referring to FIG. 1, the home hub device and at least one electronic device can be connected to the routing device to establish a network connection. At this time, the home hub device and the at least one electronic device are connected to the same wireless local area network, and the home hub device can interact with the at least one electronic device. In some cases, the user may modify the configuration information of the current network. For example, when the whole house is installed smartly, the decoration personnel may have set up the network of the home routing equipment. For example, the decoration personnel have set the network name and password, and the user receives the house Afterwards, the network configuration information is generally changed for security reasons; or in the course of daily use, the user may also modify the network configuration information. When the user modifies the network configuration information, the home hub device and at least one electronic device will disconnect from the network, and the status of each device viewed by the user on the IoT application is, for example, "not online". At this time, the user cannot control it through the IoT application individual devices.

Currently, when the home hub device and at least one electronic device are disconnected from the network, the user is required to manually restore the network connection of each device through the IoT application. FIG. 2 is a schematic diagram of a user manually repairing a network connection of an electronic device. Referring to FIG. 2 , after the user modifies the network configuration information, electronic device A, electronic device B, and electronic device C all disconnect from the network. The user needs to repair the network connections of electronic device A, electronic device B, and electronic device C respectively. Taking the user manually repairing the network connection of electronic device A as an example, the user can press the network distribution button of electronic device A to trigger electronic device A to enter the network distribution mode, or after electronic device A disconnects from the network, if it reconnects to Wi- If Fi fails, it will automatically enter the network distribution mode. After electronic device A enters the network configuration mode, the user can scan the device in the IoT application, select electronic device A in the device list obtained by scanning the device, and perform network configuration for electronic device A. Similarly, the user also needs to manually configure the network for the electronic device B and the electronic device C, so as to repair the network connection of multiple electronic devices.

It can be seen that the current method for repairing the network connection of electronic devices is relatively complicated, and requires the user to manually repair the network connections of multiple devices, which is cumbersome to operate and poor in user experience.

Based on the above problems, an embodiment of the present application provides a network restoration method. In this method, after the user manually restores the network connection of the home hub device, the home hub device can be triggered to perform network repair for other electronic devices. The home hub device can establish a secure session with other electronic devices, and deliver network configuration information to other electronic devices through the secure session, so as to assist other electronic devices to restore network connections.

Wherein, the first electronic device may be a home hub device, the first electronic device stores an identifier of at least one electronic device associated with the first electronic device, and the second electronic device is an electronic device associated with the first electronic device. Optionally, this embodiment of the present application does not limit the number of second electronic devices, and there may be only one second electronic device, or there may be multiple second electronic devices. For example, FIG. 3 shows that the system includes three second electronic devices as an example. Further, the communication system shown in FIG. 3 may further include a third electronic device, the third electronic device is associated with the first electronic device, and the physical distance between the third electronic device and the first electronic device is relatively long.

Optionally, when the coverage of a single routing device cannot meet the network connection requirements of electronic devices in the whole house, sub-routing can be set to expand the coverage of the Wi-Fi network.
