Solution Overview
Problem
The existing Wi-Fi configuration process for devices without input/output devices is inefficient, requiring a switch in access points, leading to prolonged configuration times and poor user experience due to network disconnections.
Innovation Solution
A method where a Wi-Fi mobile terminal constructs an information string with networking parameters and adds it to multicast packets, allowing the Wi-Fi device to parse and connect to a wireless router without switching access points, thereby streamlining the configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing Wi-Fi configuration process using AP mode is used, then Wi-Fi networking parameters can be configured on the Wi-Fi device, but the configuration process consumes a long time and has low efficiency
Solution Approach 1:
The patent introduces a Wi-Fi mobile terminal as an intermediary device to facilitate parameter transmission. Instead of the Wi-Fi device actively connecting to a router in AP mode, the mobile terminal acts as a mediator that receives parameters from the router and transmits them to the Wi-Fi device through multicast packets, significantly streamlining the configuration process
Solution Approach 2:
The patent implements preliminary action by having the Wi-Fi mobile terminal obtain Wi-Fi networking parameters (such as SSID and password) before the actual configuration transmission. The terminal prepares multicast packets containing configuration information in advance, allowing the Wi-Fi device to receive and apply parameters without entering time-consuming AP mode
2Ease of operation
If the AP configuration process is used, then Wi-Fi networking parameters can be configured, but the AP to which the Wi-Fi mobile terminal is connected needs to be switched, causing network disconnection
Solution Approach 1:
The Wi-Fi mobile terminal serves as a stable intermediary that maintains continuous connection to the router throughout the configuration process. The terminal receives configuration parameters and transmits them via multicast without requiring AP switching, ensuring uninterrupted network connectivity for both the terminal and router
Solution Approach 2:
The patent uses multicast packet technology to copy and transmit configuration information from the mobile terminal to the Wi-Fi device. This copying mechanism allows the configuration data to be propagated through the network without requiring the mobile terminal to disconnect or switch access points, maintaining network stability
3Ease of operation
If the existing configuration process is used, then Wi-Fi parameters can be configured, but user experience is poor due to service interruption
Solution Approach 1:
The patent ensures continuity of useful action by maintaining the mobile terminal's network connection throughout the entire configuration process. The terminal continuously remains connected to the router while performing parameter acquisition and transmission, ensuring that network services remain available and uninterrupted for the user

AI summary
This application provides a Wi-Fi configuration method, a Wi-Fi mobile terminal, and a Wi-Fi device. The Wi-Fi mobile terminal constructs an information string according to obtained Wi-Fi networking parameters, adds information of the information string to a plurality of multicast packets, and sends the plurality of multicast packets to the Wi-Fi device. The Wi-Fi device parses the plurality of received multicast packets according to a method for carrying the information string by the multicast packets, decapsulates the information string according to a method for constructing the information string, to obtain the Wi-Fi networking parameters, and further sends a connection request to a wireless router according to the obtained Wi-Fi networking parameters, to establish a connection to the wireless router. An AP to which the Wi-Fi mobile terminal is connected does not need to be switched, so that initial networking configuration of the Wi-Fi device can be quickly completed.
