Wireless Network Identifier Uniqueness for Ad-Hoc Parameter Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly those adhering to the IEEE802.11 standard, manually setting communication parameters such as SSID, encryption methods, and authentication keys is cumbersome, and existing automatic setting methods face challenges in interoperability between devices from different manufacturers, making it difficult to find and connect with a provider for communication parameters in ad-hoc networks.
Innovation Solution
A communication apparatus and method that determine a unique network identifier and create a network with this identifier, allowing for easy setting of communication parameters by broadcasting a Probe_Request signal to verify uniqueness and establish a network, ensuring only the intended provider responds, facilitating automatic parameter setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a probe request is transmitted to search for a provider in an ad-hoc network, then other apparatuses may respond to the signal, but it becomes impossible to easily search for a provider of communication parameters
Solution Approach 1:
The patent applies preliminary action by having the provider apparatus create a network with a unique network identifier before the search process begins. This pre-established network structure allows the searching apparatus to reliably identify the provider through the unique identifier, preventing other apparatuses from responding ambiguously. The network creation happens in advance, so when the probe request is transmitted, the provider is already positioned in a distinguishable state.
Solution Approach 2:
The patent uses network identifier as a distinguishing characteristic (analogous to color changes) that makes the provider apparatus visually distinguishable from other apparatuses in the network. By assigning a unique network identifier to the provider's network, the searching apparatus can easily identify and connect to the correct provider without confusion from other apparatus responses.
2Manufacturing precision
If manual input is used for setting communication parameters such as SSID, encryption method, and authentication key, then precise parameter configuration is achieved, but it becomes very troublesome for users
Solution Approach 1:
The patent implements self-service by enabling apparatuses to automatically obtain and configure communication parameters without user intervention. The searching apparatus automatically searches for a provider, receives communication parameters, and configures itself. This eliminates the need for users to manually input parameters while maintaining accurate configuration through the automatic parameter acquisition process.
Solution Approach 2:
The provider apparatus performs preliminary action by pre-configuring communication parameters and making them available for automatic acquisition. This allows the searching apparatus to automatically obtain pre-prepared parameters, eliminating manual input requirements while ensuring precise parameter configuration is achieved through the automated transfer process.
3Ease of operation
If proprietary automatic setting methods are employed by different manufacturers, then easy parameter setting is achieved within the same manufacturer's apparatuses, but interoperability between different manufacturers' apparatuses becomes impossible
Solution Approach 1:
The patent applies universality by creating a standardized network identifier-based search and connection mechanism that works across different manufacturers' apparatuses. Instead of proprietary methods, the invention uses a universal approach where any apparatus can search for providers using probe requests and connect through unique network identifiers, enabling interoperability while maintaining ease of automatic parameter setting.
Solution Approach 2:
The patent uses network identifier as an intermediary that mediates between different manufacturers' apparatuses. This intermediary mechanism allows apparatuses from different manufacturers to communicate and exchange parameters through a common protocol, bridging the gap between proprietary systems and enabling universal interoperability while preserving automatic setting functionality.

AI summary
In order to make it possible for a communication apparatus to readily detect a provider of communication parameters, the provider of communication parameters creates a network for which a network identifier that is unique among networks in the vicinity has been set, and provides a receiver, which has joined this network and requests receipt of communication parameters, with these communication parameters.
