Wireless Terminal Auto-Adapting WPS Setting Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in ad-hoc modes, setting up network settings without manual inputs is complex, and existing Wi-Fi Protected Setup (WPS) methods often fail to find compatible terminals for setup, requiring users to repeatedly change settings methods.
Innovation Solution
A wireless communication terminal equipped with a communication unit, receiving unit, setting unit, processor, and controller that automatically detects and changes setting methods to match those of other terminals, ensuring successful encrypted communication by transmitting reports and changing settings as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WPS setup methods (PBC or PIN) are used for ad-hoc mode wireless communication, then encrypted communication can be established between terminals, but the setup process fails when setting methods differ between terminals, requiring users to manually change settings
Solution Approach 1:
The terminal dynamically changes its setting method based on the setting method of the other terminal detected during the setup process. The terminal includes a changing unit that switches between PBC method and PIN method settings automatically, allowing the setup to proceed without requiring users to manually change settings multiple times.
Solution Approach 2:
The terminal uses feedback from the other terminal's setting method information to adjust its own setting method. By detecting whether the other terminal is using PBC or PIN method and receiving corresponding setting method information, the terminal can adapt its settings to match, ensuring successful setup.
2Reliability
If manual input of network setting information is required for wireless terminal setup, then secure network configuration can be achieved, but the setup process becomes time-consuming and complex
Solution Approach 1:
The terminal performs automatic setting method determination and switching without requiring manual user input. The terminal autonomously detects the other terminal's setting method, determines its own setting method accordingly, and completes the setup process automatically, eliminating time-consuming manual operations while maintaining security through encrypted communication.
Solution Approach 2:
The terminal pre-configures multiple setting methods (both PBC and PIN methods) and automatically selects the appropriate one based on the other terminal's configuration. This preliminary preparation of multiple setting options enables the terminal to quickly adapt to different scenarios without requiring users to manually reconfigure settings during setup.
3Device complexity
If a terminal uses a fixed setting method for WPS setup, then the terminal configuration remains simple, but compatibility with other terminals using different setting methods is poor
Solution Approach 1:
The terminal is designed to support multiple setting methods (both PBC and PIN methods) simultaneously and can automatically switch between them. By incorporating both setting method capabilities in one terminal, the system achieves universal compatibility with other terminals regardless of which setting method they use, without significantly increasing configuration complexity.

AI summary
A first wireless communication terminal includes: a receiver configured to receive an instruction to initiate a setting process of setting unique information to be used for a first encrypted communication with a second wireless communication terminal; a setting unit configured to set based on the instruction, a first setting method to be used for the setting process; and a processor configured to, if a first report is received from the second wireless communication terminal after the instruction is received, the first report including information indicating a second setting method to be used for the second wireless communication terminal to perform the first encrypted communication, and the first and second setting methods being identical, perform the setting process using the first setting method, and perform a set-up process of specifying an authentication method and an encryption method to be used for a second encrypted communication performed after the first encrypted communication.
