Wireless Parameter Configuration via Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of manually configuring wireless communication parameters in IEEE 802.11 networks, such as channel, SSID, encryption methods, and keys, leads to usability issues and operability problems, especially when common parameters are not recognized between devices, causing inefficient configuration processes and potential communication failures.
Innovation Solution
A communication apparatus with a storage unit for parameters and a configuration processing identifier, an acquisition unit to retrieve identifiers from other devices, and a determination unit to decide whether to use stored or acquired parameters based on matching identifiers, facilitating automatic configuration and reducing redundant parameter exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic configuration method is used to supply wireless parameters from providing apparatus to reception apparatus, then configuration work is automated and usability is improved, but encryption key exchange processing and wireless parameter encryption processing require long time
Solution Approach 1:
The providing apparatus performs encryption key exchange processing and wireless parameter encryption processing in advance before the user needs to configure parameters. The processed parameters are stored in a parameter storage unit with associated identifiers, so when configuration is needed, the pre-processed parameters can be quickly retrieved and supplied without repeating the time-consuming encryption operations.
2Adaptability or versatility
If a providing apparatus supplies different wireless parameters to a plurality of reception apparatuses, then each apparatus can be configured individually, but these apparatuses may not be capable of performing wireless communication with each other
Solution Approach 1:
A parameter management server acts as an intermediary between the providing apparatus and multiple reception apparatuses. The server stores wireless parameters and their associated identifiers, and manages the distribution of parameters to ensure that apparatuses receiving parameters can communicate with each other. The server coordinates parameter allocation to maintain network compatibility while allowing individual configuration.
3Productivity
If common wireless parameters are available between two or more wireless communication apparatuses, then communication efficiency is improved, but the operability deteriorates if a user is required to determine whether to use wireless parameters already stored or newly perform wireless parameter configuration processing
Solution Approach 1:
The reception apparatus automatically determines whether to use stored parameters or acquire new parameters by comparing configuration processing identifiers without requiring user intervention. The apparatus autonomously queries the providing apparatus for identifiers, compares them with stored identifiers, and selects the appropriate parameters automatically, eliminating the need for users to manually decide between stored and new parameters.
4Manufacturing precision
If manual input method is used to configure wireless parameters, then configuration accuracy can be controlled, but the work is complicated and time-consuming
Solution Approach 1:
The system uses automatic copying of wireless parameters from a providing apparatus to reception apparatuses through identifier matching. Instead of manual input, the parameters are copied and transferred automatically with their associated configuration processing identifiers, maintaining accuracy while eliminating the complexity and time-consuming nature of manual configuration.

AI summary
An apparatus includes a storage unit to store communication parameters and a configuration processing identifier allocated to the communication parameters and an acquisition unit to acquire a configuration processing identifier from another apparatus. The apparatus determines whether to use communication parameters stored in the storage unit or acquire communication parameters from other communication apparatus, based on the configuration processing identifier stored in the storage unit and the configuration processing identifier acquired by the acquisition unit.
