Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face a decrease in user convenience when switching frequency bands, leading to potential communication disruptions between devices operating as access points.
Innovation Solution
An information processing apparatus that operates as an access point, allowing frequency band changes without interrupting communication by maintaining the new setting until it restarts as an access point, ensuring seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the frequency band is changed while operating as an access point, then communication speed is improved, but communication between apparatuses may be cut off causing decrease in user convenience
Solution Approach 1:
The system performs preliminary actions by saving the current connection information (IP address, port number, protocol) before changing the frequency band. This allows the apparatus to quickly restore communication after the band change by reusing the saved connection information, thus maintaining user convenience while enabling frequency band switching for improved communication speed.
Solution Approach 2:
The connection information management unit acts as an intermediary that stores and manages connection information during the frequency band change process. This intermediary component ensures that connection data is preserved and can be restored after the frequency band switch, preventing communication cutoff and maintaining ease of operation.
2Reliability
If the frequency band is changed while operating as an access point, then communication quality is improved, but communication continuity deteriorates
Solution Approach 1:
The system performs preliminary actions by capturing and storing connection information (IP address, port number, protocol) before initiating frequency band change. This preliminary data preservation enables rapid restoration of communication after the band change, maintaining communication continuity while allowing quality improvement through frequency band optimization.
Solution Approach 2:
The system ensures continuity of useful action by immediately restoring communication using saved connection information after the frequency band change. The connection restoration process is seamless and maintains continuous communication, preventing interruptions while still allowing the system to switch to a better frequency band for improved communication quality.
3Speed
If the frequency band setting is changed, then communication performance is improved, but connection stability deteriorates
Solution Approach 1:
The system performs preliminary action by saving all necessary connection information (IP address, port number, protocol) before changing the frequency band setting. This pre-saved information acts as a stability anchor, allowing the system to switch frequency bands for improved performance while guaranteeing stable reconnection through the preserved connection parameters.
Solution Approach 2:
The system selectively changes only the frequency band parameter while keeping other connection parameters (IP address, port number, protocol) unchanged. This targeted parameter change approach improves communication performance by switching frequency bands while maintaining connection stability through preservation of other critical connection parameters.

AI summary
An information processing apparatus performs control such that, when a setting of a frequency band is changed while the information processing apparatus is operating as an access point, the frequency band is not changed before the information processing apparatus stops operating as the access point, and the information processing apparatus operates based on the changed setting of the frequency band when newly starting operating as the access point after stopping operating as the access point.
