Wi-Fi Multi-Link Handover Reconfiguration for Data Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in maintaining data continuity during handover transitions between access point devices, as they require re-association and re-establishment of protocols, leading to connectivity disruptions.
Innovation Solution
A method and apparatus for enabling seamless transitions between access point multi-link devices (AP MLDs) by transmitting and receiving first frames for link reconfiguration, optimizing the link reconfiguration protocol to maintain data continuity during handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If re-association and re-establishment of protocols are performed during handover, then the handover transition can be completed, but data continuity is disrupted
Solution Approach 1:
The patent performs link reconfiguration and protocol re-establishment in advance during the handover process. The target AP MLD receives and processes reconfiguration frames before the actual handover occurs, preparing the data transmission paths and protocol contexts beforehand. This preliminary action ensures that when the handover is completed, data continuity is maintained without disruption.
2Reliability
If link reconfiguration is optimized, then data continuity can be maintained during handover, but the complexity of the handover protocol increases
Solution Approach 1:
The patent merges the link reconfiguration process with the existing handover protocol. Instead of treating them as separate operations, the reconfiguration frames are integrated into the handover message exchange between AP MLDs. This combining approach maintains data continuity while avoiding the need for entirely separate complex protocols, as the reconfiguration information is carried within the existing handover frame structure.

AI summary
The present application belongs to the field of Wi-Fi. Disclosed are a handover method, and an apparatus, a device, a medium and a program product. The method is executed by a non-AP MLD, and comprises: sending and/or receiving at least one first frame, which is used for implementing a handover between two AP MLDs at different positions on the basis of link reconfiguration. In the method, by means of sending and/or receiving at least one first frame, which is used for implementing a handover between two AP MLDs at different positions on the basis of link reconfiguration, a link reconfiguration protocol between the two AP MLDs at different positions is optimized, and the handover of the non-AP MLD between the two AP MLDs during a communication process is implemented.
