Multi-Link Wi-Fi TID Mapping Using AI Network Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The negotiation efficiency for TID-to-link mapping in multi-link devices is low due to the lack of knowledge of the receiving end's requirements, hindering quick establishment of accurate mapping, and existing mechanisms struggle to prioritize delay-sensitive traffic streams in dynamic network environments.
Innovation Solution
An AP MLD determines TID-to-link mapping information using a first network model, such as AI/ML, to predict optimal link sets for delay-sensitive and non-delay-sensitive traffic streams, broadcasting this information to associated Non-AP MLDs, ensuring timely and efficient mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a negotiation mechanism is used to establish TID-to-link mapping between multi-link devices, then the mapping can be established through request-response processes, but the negotiation efficiency is low because the sending end does not know the receiving end's requirements
Solution Approach 1:
The receiving end pre-generates multiple candidate TID-to-link mapping relationships and sends them to the sending end in advance. This preliminary action eliminates the need for iterative negotiation, as the sending end can directly select from the pre-prepared options based on its own requirements, thereby improving negotiation efficiency and ensuring the receiving end's requirements are met.
2Adaptability or versatility
If traditional mapping mechanisms are used, then the system can maintain simplicity, but it cannot prioritize delay-sensitive traffic streams in dynamic network environments
Solution Approach 1:
The patent applies different mapping strategies to different traffic types. Delay-sensitive traffic is assigned to links with lower latency characteristics, while non-delay-sensitive traffic uses other links. This local differentiation in mapping quality enables priority handling of delay-sensitive traffic without requiring complete redesign of the entire mapping mechanism.
Solution Approach 2:
The TID-to-link mapping relationships are dynamically adjusted based on real-time network conditions. The receiving end generates updated candidate mappings when network state changes, allowing the system to adapt to dynamic environments and prioritize delay-sensitive traffic according to current link qualities and conditions.
