Wireless Parameter Sharing with Split Notifications and Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication parameter sharing methods, such as using two-dimensional codes, are vulnerable to unauthorized access and result in significant time delays due to channel scanning for wireless communication.
Innovation Solution
A communication apparatus with a first notification unit providing unique information and channel details, a second notification unit without channel information, and a reception unit that waits for signals on a predetermined or multiple channels to securely and efficiently share communication parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access point displays a two-dimensional code containing information on the communication parameters, then the communication parameters can be easily set by capturing and decoding the code, but the communication parameters could be acquired by an unintended apparatus
Solution Approach 1:
The patent extracts the channel information from the two-dimensional code and handles it separately through notification units. The QR code contains only unique device information, while channel information is transmitted through dedicated notification channels, preventing unauthorized apparatus from obtaining both pieces of information simultaneously.
Solution Approach 2:
The patent introduces notification units as intermediaries between the access point and communication apparatus. These notification units securely transmit channel information and establish communication channels before the actual parameter sharing occurs, adding a security layer that prevents unauthorized access.
2Reliability
If the communication apparatus searches for a channel that the different apparatus uses to share parameters by wireless communication, then the parameters can be shared securely, but there is a significant time delay
Solution Approach 1:
The patent performs preliminary actions by including channel information in the notification units and establishing communication channels before the actual parameter sharing process. This allows the communication apparatus to know in advance which channel to use, eliminating the need for time-consuming channel scanning during parameter sharing.
3Productivity
If the first notification unit provides information on a predetermined channel for sharing parameters, then the parameter sharing process is faster, but the system requires more complex notification mechanisms
Solution Approach 1:
The patent segments the information transmission into two distinct notification units: one for unique device information and another for channel information. This segmentation allows each unit to have a specific, simplified function while collectively achieving fast and secure parameter sharing.

AI summary
A communication apparatus includes a first notification unit, a second notification unit, a reception unit, and a sharing unit. The first notification unit provides first information containing information unique to the communication apparatus and information on a predetermined channel for use in sharing a communication parameter for wireless communication with a different communication apparatus. The second notification unit provides second information containing the information unique to the communication apparatus but not containing information on the predetermined channel. When the first information is provided, the reception unit waits to receive a predetermined signal containing information corresponding to the information unique to the communication apparatus without shifting to another channel. When the second information is provided, the reception unit waits to receive the predetermined signal using a plurality of channels. When the predetermined signal is provided, the sharing unit shares the communication parameter with the different communication apparatus.
