Automatic WLAN Connection Setup Using Random Parameter Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and complexity when setting up Wireless Local Area Network (WLAN) connections between digital devices, particularly in Ad-hoc mode, as they need to manually input Service Set Identifier (SSID), security keys, and IP addresses, which is time-consuming and requires knowledge of WLAN and IP address management software.
Innovation Solution
A method for automatically connecting digital devices using random information to generate and set SSID, security keys, and IP addresses, allowing for WLAN communication without user input, with one device displaying a random number for the other to input, enabling connection without requiring input means other than for initiating the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of SSID, security key, and IP address is required for WLAN connection, then connection security and configurability are maintained, but user operation complexity and setup time increase significantly
Solution Approach 1:
The system automatically generates and configures SSID, security key, and IP address without requiring manual user input. The first digital device autonomously performs the connection setup by generating random information and configuring all necessary WLAN parameters, enabling self-service connection establishment.
Solution Approach 2:
The first digital device generates random information and pre-configures all connection parameters (SSID, security key, IP address) before the second device attempts to connect. This preliminary configuration eliminates the need for manual setup during the actual connection process.
2Reliability
If manual WLAN configuration is required, then connection security is maintained through user-defined parameters, but device complexity and user knowledge requirements increase
Solution Approach 1:
The system automatically generates and configures SSID, security key, and IP address without requiring manual user input. The first digital device autonomously performs the connection setup by generating random information and configuring all necessary WLAN parameters, enabling self-service connection establishment.
3Ease of operation
If random information is used for automatic connection, then setup time is reduced and ease of operation improves, but information security may be compromised through display requirements
Solution Approach 1:
The random information is extracted and displayed only on the first digital device's display unit, eliminating the need for physical keyboards or input devices. This extraction of the input function to a display-only interface reduces security risks associated with physical input devices while maintaining automatic connection capabilities.

AI summary
A method and apparatus for performing an automatic wireless connection with a second digital device by a first digital device is provided. The method includes acquiring, by the first input device, random information used for the wireless connection; checking a status of a Wireless Local Area Network (WLAN); storing the checked status; setting the WLAN to an Ad-hoc mode; setting a Service Set Identifier (SSID) of the WLAN using the random information; setting a security key of the WLAN using the random information; and setting an Internet Protocol (IP) address of the WLAN using the random information.
