Communication Apparatus Code-Based Authentication Wireless Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication techniques that add information necessary for setting communication parameters to wireless frames can limit wireless resources, as multiple devices transmitting frames with added information elements consume bandwidth, particularly during searches for connection partners.
Innovation Solution
A communication apparatus that captures and processes code information to authenticate and mediate wireless connections, using a smaller amount of information for search signals, thereby reducing the load on wireless resources by transmitting search identification information in a broadcast frame and certification information via unicast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information necessary to set a communication parameter is added to a communication frame, then it is possible to transmit information for setting communication parameters, but the wireless resource becomes limited
Solution Approach 1:
The patent segments the communication parameter information into two parts: certification information (smaller size) and detailed communication parameters (larger size). The certification information is transmitted in broadcast frames to all devices, while the detailed parameters are transmitted only to authenticated devices through unicast communication. This segmentation reduces the amount of information that needs to be broadcast to all devices, thereby conserving wireless resources.
Solution Approach 2:
The patent introduces a certification mechanism as an intermediary. Instead of transmitting all communication parameters directly, the system first transmits a compact certification token that serves as proof of authentication. This intermediary certification information enables subsequent secure transmission of detailed parameters through unicast channels, reducing broadcast overhead while maintaining security.
2Adaptability or versatility
If multiple apparatuses transmit response signals with added information elements, then each apparatus can respond to the search, but the wireless resource becomes more limited
Solution Approach 1:
The patent segments the response transmission into two phases: first, multiple devices respond with compact certification information in broadcast frames; second, detailed parameter exchange occurs through targeted unicast communication. This segmentation allows multiple devices to participate in the authentication process efficiently while minimizing the wireless resource consumption associated with broadcasting large amounts of information from each device.
Solution Approach 2:
The patent implements partial action by having devices transmit only the necessary certification token in broadcast responses rather than complete parameter sets. The full parameter exchange is performed selectively through unicast channels based on authentication results. This partial transmission approach enables multiple devices to respond efficiently without exhausting wireless resources.

AI summary
A communication apparatus executes an authentication process with a first other communication apparatus based on information acquired from an image obtained by capturing code information of the communication apparatus and receives, from the first other communication apparatus, first information shared between the first other communication apparatus and a second other communication apparatus. The communication apparatus transmits a search signal including second information based on the received first information and has a smaller amount of information than the first information, and transmits the first information to the second other communication apparatus in a case where a response signal in response to the search signal is received from the second other communication apparatus, and then executes a setting process for setting a communication parameter for communicating with the second other communication apparatus.
