QoS Frame Handover Parameters for Seamless AP Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting Quality of Service (QoS) data frames in Ultra High Reliability (UHR) Wi-Fi networks fail to support seamless transitions of stations (STAs) between access points (APs), leading to inefficiencies and potential data loss during handovers.
Innovation Solution
A method for transmitting QoS data frames that accumulates or restarts transmission parameters, such as retry counts, MSDU timers, and lifetime, upon transitions between APs, ensuring uninterrupted data transmission by buffering or discarding frames based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the STA transitions from one AP to another AP in UHR Wi-Fi networks, then the STA can maintain connection and continue communication, but the existing QoS data frame transmission methods fail to support seamless transitions leading to data loss and transmission interruptions
Solution Approach 1:
The patent applies preliminary action by having the source AP send the transmission parameter (such as retry count, MSDU timer value, or lifetime) to the target AP before the STA completes its transition. This allows the target AP to have the necessary parameter information ready, ensuring seamless continuation of QoS data frame transmission without interruption or data loss during the handover process
Solution Approach 2:
The patent uses the source AP as an intermediary to transfer the transmission parameter from the source AP to the target AP. This intermediary mechanism ensures that the critical transmission parameter is accurately conveyed during the transition, enabling the target AP to maintain the same QoS transmission characteristics as the source AP, thus resolving the contradiction between reliability and adaptability
2Reliability
If transmission parameters are not accumulated or restarted during STA transition, then the transmission process can be simplified, but data loss occurs and transmission integrity cannot be maintained
Solution Approach 1:
The patent applies parameter changes by having the target AP either accumulate the transmission parameter from the source AP or restart counting based on the received parameter. This dynamic parameter management ensures that the transmission characteristics (retry count, timer values, lifetime) are properly maintained across the transition, achieving reliability while the complexity is managed through standardized parameter handling procedures

AI summary
Embodiments of the present disclosure relate to the technical field of mobile communications, and provide a quality of service (QoS) data frame transmission method, an electronic device and a storage medium. The QoS data frame transmission method is applied to a receiving end. The method comprises: determining transmission parameters of a QoS data frame, wherein the transmission parameters are accumulated transmission parameters of a station device STA before switching from a first AP to a second AP, or the transmission parameters are re-counted after switching from the first AP to the second AP; and receiving the QoS data frame according to the transmission parameters. The embodiments of the present disclosure provide a transmission mode of a QoS data frame.
