Fast AP Transition Pre-Negotiation for TWT and Link Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, stations transitioning from a serving access point to a target access point often fail to pre-negotiate information prior to association, leading to prolonged resumption of communication after the transition.
Innovation Solution
Implementing Fast Basic Service Set Transition Protocol and Fast Transition Resource Request Protocol for pre-negotiating information such as Target Wake Time (TWT), Restricted TWT (R-TWT), or Traffic Identifier (TID)-to-link mapping to facilitate faster access point transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If pre-negotiation is performed using Fast Basic Service Set Transition Protocol or Fast Transition Resource Request Protocol, then the communication resumption time is reduced, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by performing pre-negotiation of TWT, R-TWT, and TID-to-link mapping information before the actual access point transition occurs. The station and target access point exchange and agree upon these parameters in advance during the association process, so that when transition happens, the communication can be rapidly resumed without needing to negotiate these parameters afterward, thus reducing communication resumption time despite adding negotiation steps beforehand
2Speed
If multiple negotiation protocols are implemented for fast transition, then the transition speed is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements universality by designing the negotiation mechanism to handle multiple types of information (TWT, R-TWT, and TID-to-link mapping) within a unified negotiation framework. The Fast Basic Service Set Transition Protocol and Fast Transition Resource Request Protocol are designed to carry various negotiation elements in a standardized manner, allowing the system to handle different transition scenarios and information types through a common multi-functional negotiation process, thereby improving transition speed while maintaining operational ease

AI summary
The present application belongs to the field of communications. Disclosed are a negotiation method and apparatus based on a fast-transition access point, and a device, a medium and a program product. The method is executed by a station, and comprises: by means of a fast basic service set transition protocol and/or a fast-transition resource request protocol, performing advanced negotiation with a target access point regarding first information, wherein the first information comprises at least one of a TWT, an R-TWT, and mapping from a flow identifier to a link. In the method, advanced negotiation regarding first information is performed with a target access point by means of a fast basic service set transition protocol and/or a fast-transition resource request protocol, such that advanced negotiation regarding at least one of a TWT, an R-TWT, and the mapping from a flow identifier to a link can be implemented, thereby resuming communication faster, which communication is interrupted due to transition.
