Wireless Network Access Reconfiguration for Elevated Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network configuration methods for terminal devices require hardware capabilities such as physical buttons or a camera for inputting characters or scanning QR codes, and reconfiguration is inconvenient, especially for devices installed at high positions.
Innovation Solution
A network access method involving a network access device that broadcasts messages to terminal devices, allowing authentication and secure network access without direct input of network details, eliminating the need for physical buttons or a camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device uses traditional network configuration methods (manual input or QR code scanning), then network access can be established, but the terminal device requires specific hardware (physical buttons, touch screen, or camera) and the reconfiguration process becomes inconvenient when the device is installed at high positions
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the user and the terminal device. The mobile terminal displays authentication information and transmits network configuration data wirelessly to the terminal device, eliminating the need for the terminal device to have input hardware. This mediator approach allows configuration without requiring buttons, screens, or cameras on the terminal device itself.
Solution Approach 2:
The patent replaces mechanical input methods (physical buttons, touch screens) and optical scanning (camera-based QR code reading) with wireless communication. Network configuration data is transmitted through wireless signals from the mobile terminal to the terminal device, substituting mechanical and optical systems with electromagnetic field-based communication.
2Reliability
If the terminal device is installed at an elevated position for security monitoring, then effective area monitoring is achieved, but direct operation for reconfiguration becomes impossible without dismantling the device
Solution Approach 1:
The mobile terminal serves as a mediator that allows users to configure the terminal device remotely without physical contact. The user operates the mobile terminal to transmit authentication information and network configuration data wirelessly to the elevated terminal device, making reconfiguration possible without dismantling or physically accessing the device at its installation location.
Solution Approach 2:
The terminal device automatically receives and processes network configuration data through its wireless communication module without requiring manual intervention. The device can autonomously complete the configuration process by receiving data packets from the mobile terminal, reducing the need for physical access and manual setup operations.

AI summary
A network access method, a system and a terminal device are provided by present application. The method includes broadcasting first network message of the network access device, the first network message is used for a terminal device to access a first network of the network access device; receiving authentication information sent by the terminal device through the first network; determining whether the terminal device has passed network access authentication based on the authentication information; and in response that the terminal device passes the network access authentication, sending a second network message to the terminal device through the first network, the second network message is used for the terminal device to access a second network. The method may reduce hardware requirements for terminal devices requiring network configuration and facilitates the reconfiguration of terminal devices.
