Code-Based Wireless Network Registration for Authorized Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face usability issues due to the need for multiple devices to execute similar authentication processes to set communication parameters, complicating the operation and potentially allowing unauthorized devices to connect to a network.
Innovation Solution
A communication apparatus is equipped with an authentication unit to set communication parameters and execute authentication processing, allowing only authorized devices to register as management apparatuses by capturing and decoding code information, thereby simplifying the registration process and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all apparatuses with image-capturing function can set communication parameters, then ease of operation is improved, but security deteriorates due to unauthorized apparatus connection
Solution Approach 1:
The patent introduces a base station as an intermediary between the mobile terminal and the access point. The base station verifies whether the mobile terminal has the authority to set communication parameters before allowing it to do so. This mediator resolves the contradiction by enabling easy parameter setting through the mobile terminal while preventing unauthorized apparatuses from connecting, as the base station filters out unauthenticated devices.
2Reliability
If multiple devices execute authentication processing to set communication parameters, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the authentication and parameter-setting functions into a unified process coordinated by the base station. Instead of requiring separate authentication steps for each device pair, the base station centralizes the authentication process and manages parameter distribution. This reduces device complexity while maintaining security, as the base station handles the complex authentication logic rather than distributing it across multiple devices.

AI summary
A communication apparatus includes an authentication unit that sets a communication parameter for connecting to a wireless network, and executes authentication processing, with a base station, for registering the communication apparatus to the base station that forms the wireless network, as a management apparatus that is allowed to connect another apparatus to the wireless network, a setting unit that, based on information acquired from code information captured through imaging, sets the communication parameter to another communication apparatus corresponding to the code information, and a registration unit that executes registration processing for registering the other communication apparatus to the base station as the management apparatus, based on at least a condition that the communication parameter is set to the other communication apparatus by the setting unit.
