Communication Apparatus Resolving Network Identifier Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with little knowledge find it difficult to set up wireless communication systems without access points, as overlapping SSID and IP addresses can lead to communication failures, and existing solutions do not effectively address this issue across various communication standards.
Innovation Solution
The communication apparatus automatically generates and manages SSID and IP addresses, and changes frequency channels to prevent overlap, using a CPU-controlled system with specific units for detection and avoidance of setting conflicts, allowing for seamless wireless communication setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually set SSID and IP addresses for wireless communication, then communication can be established, but users with little knowledge cannot perform the setting correctly and overlap occurs
Solution Approach 1:
The communication apparatus automatically generates its own SSID by incorporating its IP address and terminal identifier, and autonomously detects and resolves overlaps with other apparatuses. This self-service mechanism eliminates the need for manual user configuration while ensuring reliable communication through automatic conflict resolution.
Solution Approach 2:
The system dynamically changes the SSID parameter by incorporating the IP address and terminal identifier into the SSID generation process. When overlap is detected, the system automatically modifies the SSID by changing the IP address or terminal identifier, thereby resolving the conflict without user intervention.
2Ease of operation
If automatic SSID generation using IP address and terminal identifier is implemented, then ease of setup is improved, but communication failure occurs when overlap with other apparatuses happens
Solution Approach 1:
The communication apparatus continuously monitors the wireless environment by detecting beacon signals from other apparatuses. When overlap is detected through this feedback mechanism, the system automatically changes its IP address or terminal identifier to eliminate the conflict, ensuring continuous reliable communication.
Solution Approach 2:
Before establishing communication, the apparatus performs preliminary detection of the wireless environment to identify potential overlaps. By detecting and resolving conflicts before communication begins, the system prevents communication failures rather than reacting to them afterward.
3Adaptability or versatility
If multiple communication apparatuses use the same frequency channel, then wireless communication can occur, but overlap of frequency channel causes communication failure
Solution Approach 1:
The system dynamically changes the frequency channel parameter when overlap is detected. By automatically selecting a different frequency channel that does not conflict with other apparatuses, the system maintains communication stability while adapting to the wireless environment.

AI summary
A communication apparatus (100) is capable of making wireless communication without using an access point, by using a network identifier having communication identification information identifying a class of communication setting containing an IP address and frequency information. The communication apparatus (100) includes: a detecting unit (117) that detects another communication apparatus causing failure of the wireless communication due to overlap of the network identifier; and a changing unit (118) that changes the network identifier when the detecting unit (117) detects another communication apparatus causing failure of the wireless communication. The changing unit (118) changes the network identifier so as to change the IP address of the communication apparatus (100) or a frequency that the communication apparatus (100) uses.
