Multi-Link Shared Access Point Handover Without Link Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face instantaneous interruptions during handover operations when switching access points in multi-link communication, necessitating a solution to seamlessly transition between access points without disrupting the wireless connection.
Innovation Solution
A sharing access point with a management unit that designates an anchor link and manages the handover process to maintain wireless connections during transitions, ensuring seamless switching between access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handover operation is performed to switch access point for one or more links, then connection destination switching is achieved, but instantaneous interruption occurs where wireless connection is cut off in all links
Solution Approach 1:
The handover operation is segmented into two phases: first, the access point is switched for links other than the anchor link while maintaining the anchor link connection; second, the anchor link is switched after ensuring all other links have been switched. This segmentation prevents simultaneous disconnection of all links, thereby avoiding instantaneous interruption.
Solution Approach 2:
The management unit performs preliminary actions by first switching the access point for links other than the anchor link before switching the anchor link. This preliminary switching of non-anchor links ensures that at least one link (the anchor link) maintains continuous connection during the handover process, preventing instantaneous interruption.
2Loss of time
If access point is switched for all links simultaneously, then handover is completed quickly, but wireless connection is cut off in all links causing instantaneous interruption
Solution Approach 1:
The handover process is divided into sequential steps: first switching non-anchor links, then switching the anchor link. This segmentation extends the handover time slightly but ensures continuous connection, avoiding the harmful effect of instantaneous interruption that would occur with simultaneous switching of all links.
Solution Approach 2:
The management unit ensures continuous useful action by maintaining the anchor link connection during the handover process. While the anchor link remains connected, data transmission continues without interruption. The anchor link is switched only after all other links have been successfully switched, ensuring continuous connectivity throughout the handover operation.

AI summary
In a sharing access point according to an embodiment, a management unit sets one of a plurality of links from a terminal as an anchor link, corresponding to reception of a handover request for requesting switching of a shared access point to serve as a connection destination for one or more of the plurality of links from the terminal. The management unit switches the shared access point to serve as the connection destination for a switching target link among the links other than the anchor link in a state of maintaining wireless connection with the shared access point to serve as the connection destination in the anchor link.
