Server-Based Wireless LAN Connection Setup via Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless LAN spot systems are cumbersome for setting connections between communication devices due to complex procedures and the inability to dynamically change or increase setting information, leading to potential leakage of confidential data when embedded in images.
Innovation Solution
A system comprising a server that manages and distributes setting information upon request, and a communication apparatus that reads and converts code information into setting information, allowing for dynamic changes and secure transmission, using a URI-based approach to separate the data path from the image encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If setting information is embedded in bar code or image, then connection setting can be automated, but the setting information cannot change once generated and confidential information may be leaked
Solution Approach 1:
The patent divides the setting information into two parts: a static code portion embedded in the bar code/image that can be automatically read, and a dynamic server portion that contains the actual connection settings. This segmentation allows the bar code to remain simple and scannable while the server stores and manages the flexible, updatable connection information.
Solution Approach 2:
The patent introduces a server as an intermediary between the bar code and the connection settings. The bar code contains only a reference to the server, not the actual settings. This intermediary allows automatic retrieval of setting information while enabling centralized management, updates, and security control of the connection parameters.
2Extent of automation
If setting information is embedded in bar code, then connection can be established automatically, but large amounts of setting information cannot be embedded
Solution Approach 1:
The patent extracts the actual connection setting information from the bar code and stores it on the server. The bar code contains only a minimal reference (server address and identifier), while the complete setting information is retrieved dynamically from the server. This extraction solves the limitation of bar code storage capacity.
Solution Approach 2:
The patent moves the storage dimension from the two-dimensional bar code to the network dimension. Instead of embedding all settings in the bar code, the system uses the network to store and retrieve the setting information, effectively adding a new dimension for information storage and access.
3Reliability
If wireless LAN connection setting is performed manually, then connection information can be customized, but the setting procedure becomes complex and time-consuming
Solution Approach 1:
The patent performs preliminary action by pre-configuring all connection settings on the server before the actual connection process. When a user scans the bar code, the settings are automatically retrieved and applied without requiring manual configuration. This preliminary setup on the server eliminates time-consuming manual operations while maintaining accurate, customized settings.

AI summary
A system for setting a connection between information processing devices, according to the present invention includes: a server apparatus which is arranged on a network, collectively manages setting information necessary for a connection between other devices, and distributes requested setting information according to a request from another apparatus; and a communication apparatus which transmits information to the server apparatus. The communication apparatus includes: a first reading unit which makes displayed or printed code information readable, the code information indicating a location of setting information necessary for a connection to another device; a second reading unit which reads the code information; a converting unit which converts the code information into the location of the setting information; an acquiring unit which acquires the setting information from the location of the setting information; and a connection setting unit which performs a connection setting based on the setting information.
