Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

Embodiment 1 A wireless channel reallocation method. The method of this embodiment will be described below with reference to FIG. 1.

In FIG. 1, S100, the wireless routing device receives a command for selecting an optimal wireless channel transmitted by the control device.

Specifically, the wireless routing device in this embodiment corresponds to a control device, which is a terminal device capable of triggering a wireless routing device to reallocate its wireless channel, such as a terminal device installed with a wireless routing device management application. The control device may be specifically a smart terminal device such as a smart mobile phone, a notebook computer or a tablet computer, and the control device is usually a smart mobile terminal device.

The wireless routing device may store identification information of the control device, such as a media access control (MAC) address of the control device or a mobile phone number or an account of an instant message stored in the wireless routing device. The identification information of the above control device should be able to uniquely identify the control device.

The command for selecting the optimal wireless channel may be that the control device actively sends the message to the wireless routing device. In a specific example, when the user finds that the network speed is slow and cannot meet the requirements of the Internet access, the user may click on the control device. The corresponding application (such as a wireless routing device management application that can provide wireless channel reallocation function) enables the corresponding application to be in operation, and the user can actively send the control device to the wireless routing device by activating the reallocation of the wireless channel function in the application. The command to select the optimal wireless channel; another specific example, when the user finds that the network speed is slow and cannot meet the requirements of the Internet access, by clicking on the corresponding application in the control device (such as wireless that can provide wireless channel reallocation function) The routing device management application is configured to enable the corresponding application to be in a running state, and the user can enable the control device to send a detection current working channel request to the wireless routing device by activating the function of detecting the current working channel in the application, and the wireless routing device receives the control device transmission. The current test After the working channel is requested, the channel quality of the current working channel is detected, and the channel quality information of the current working channel obtained by the detection is transmitted to the control device, and the control device displays the channel quality information of the current working channel transmitted by the wireless routing device to the control device. If the user finds that the channel quality of the current working channel is poor or poor according to the information displayed by the control device, the user can enable the control device to actively send the optimal selection to the wireless routing device by activating the function of reallocating the wireless channel in the application. The command of the wireless channel.

In the above description, after receiving the channel quality information of the current working channel from the wireless routing device, the control device may prompt the user to control the channel quality information of the current working channel transmitted by the wireless routing device, such as on the control device. Wireless routing device management application icon flashing or graph The identifier of the received new information is displayed on the label; after the user clicks the application icon, the wireless routing device management application provides a display screen for the user, and the display screen includes channel quality information of the current working channel that is newly received by the control device.

The device management application can correspondingly generate a command to select an optimal wireless channel, and the control device transmits the command for selecting the optimal wireless channel to the wireless routing device.

The command for selecting the optimal wireless channel may also be sent by the control device to the wireless routing device according to the request of the wireless routing device, that is, the control device passively sends the selection of the optimal wireless channel to the wireless routing device according to the request of the wireless routing device. Command; a specific example, the wireless routing device periodically detects the channel quality of its current working channel, and the wireless routing device actively sends the selection optimal wireless to the control device when determining that the channel quality of its current working channel is lower than the channel quality threshold. The channel request, after receiving the selection of the optimal wireless channel request transmitted by the wireless routing device, the control device prompts the user whether to interrupt the wireless network and perform wireless channel reallocation. If the control device receives the characterization of the user input, the wireless network needs to be interrupted. After the information of the wireless channel reallocation is performed, the control device generates a command for selecting an optimal wireless channel, and sends the command for selecting the optimal wireless channel to the wireless routing device, and if the control device receives the characterization of the user input, the wireless network does not need to be interrupted. of After the message, the control device may generate no selection radio channel carrying the optimal wireless channel reallocation response, and sends the response to the wireless routing device.
