Communication Apparatus Preventing Wireless LAN Resource Shortage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless LAN communication systems, devices incompatible with P2P communication can unintentionally reconnect after cutting communication, leading to a shortage of wireless LAN resources due to automatic reconnection, which existing technologies fail to prevent effectively.
Innovation Solution
A communication apparatus with a system-control unit that manages connection information and changes it when a request is received from a non-P2P compatible device, disabling automatic reconnection and preventing unintended requests by storing and deleting request-having information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection information is maintained for automatic reconnection, then ease of operation is improved, but wireless LAN resources are depleted due to unintended reconnections from non-P2P compatible devices
Solution Approach 1:
The system performs preliminary classification of connection requests to identify whether they come from P2P-compatible or non-P2P-compatible devices before allowing reconnection. By proactively managing connection information based on device compatibility type, the system prevents unintended automatic reconnections from non-P2P devices while maintaining automatic reconnection functionality for P2P-compatible devices, thus resolving the contradiction between ease of operation and resource conservation
2Reliability
If connection information is changed frequently, then security is improved by preventing unintended requests, but reliability deteriorates due to connection instability
Solution Approach 1:
The system applies different connection management strategies to different device types: P2P-compatible devices receive standard connection management with stable connection information, while non-P2P-compatible devices have their connection information changed or deleted. This localized differentiation ensures security against unintended requests from non-P2P devices without disrupting the connection stability required by P2P-compatible devices
3Ease of operation
If automatic reconnection is enabled, then ease of operation is improved, but device complexity increases due to need for compatibility detection
Solution Approach 1:
The system introduces a connection information management unit that acts as an intermediary between connection requests and the actual connection process. This unit automatically detects device compatibility type and manages connection information accordingly, shielding users from the complexity of compatibility detection while maintaining automatic reconnection functionality. The intermediary handles the complexity internally, allowing users to benefit from automatic reconnection without needing to understand or configure compatibility settings

AI summary
Provided is a communication apparatus for preventing a shortage of wireless LAN resources. A communication-control unit controls wireless communication via an access point and P2P type communication (P2P communication); a connection-information-managing unit manages connection information of the access point, and request-having information that indicates there is a connection request from a portable terminal using the wireless communication; and a system-control unit causes the connection-information-managing unit to change the connection information when the connection-information-managing unit is managing the request-having information. By changing the connection information of the access point when there is a connection request from a portable terminal using wireless communication, automatic connection that is executed after cutting communication is selected on the portable terminal side is disabled so that unintended connection requests are not received from the portable terminal side.
