Communication Apparatus Log Management via Parameter Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as those using NFC for handover to wireless LAN, face challenges in managing communication parameters effectively, leading to cluttered logs and hindering the selection of desired parameters due to random generation and storage of communication parameters.
Innovation Solution
A communication apparatus with sharing, holding, retrieval, connection, disconnection, and deletion means to manage wireless communication logs by sharing communication parameters, retrieving beacons, establishing connections, disconnecting, and deleting unused parameters to maintain a clean log.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication parameters are randomly generated every time a network is generated to improve security, then security is improved, but the log becomes cluttered with unused parameters making parameter selection difficult
Solution Approach 1:
The patent applies the discarding principle by automatically deleting communication parameters from the log after they are used for handover connection. When a parameter is used to establish a wireless LAN connection via NFC handover, the system removes that parameter from the log to prevent clutter. This maintains security through random generation while improving ease of operation by keeping the log clean and manageable.
2Ease of operation
If communication parameters are stored in the log to simplify connection procedure, then ease of operation is improved, but the log becomes cluttered and security is compromised
Solution Approach 1:
The patent applies dynamics by making the log contents dynamic rather than static. Parameters are added to the log when generated and automatically removed after use. This dynamic management allows the log to serve its purpose of simplifying connection procedures while preventing security issues and clutter from accumulated unused parameters.
3Ease of operation
If NFC handover is used to share communication parameters to wireless LAN to simplify connection, then ease of operation is improved, but more parameters are left in the log creating clutter
Solution Approach 1:
The patent specifically addresses the NFC handover scenario by implementing automatic deletion of parameters that were used for handover connections. When a parameter is shared via NFC and used to establish a wireless LAN connection, the system identifies and deletes that parameter from the log. This maintains the convenience of NFC handover while preventing log clutter from accumulating.

AI summary
A communication parameter is shared with an external apparatus and is held via second communication different from first communication. In the case where a connection with the external apparatus, which is started in response to sharing of the communication parameter, is disconnected, a communication parameter used in the disconnected connection is deleted.
