Wireless Stream Classification With Dynamic QoS Tier Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stream classification service (SCS) protocols support only a single level of quality of service (QoS), which is insufficient for modern applications like streaming video and augmented/virtual reality, as they do not allow for signaling of multiple QoS tiers, making it difficult for networks to balance the needs of different flows.
Innovation Solution
Implementing a method and system that enable multiple quality tiers for wireless communication by allowing wireless stations (STAs) to signal multiple QoS levels and profiles, enabling the wireless access point (AP) to dynamically switch between these tiers based on network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single level of QoS is supported for an SCS flow, then the protocol complexity is reduced and implementation is simpler, but the ability to accommodate modern applications with multiple quality tiers (video streaming, AR, VR) is insufficient
Solution Approach 1:
The QoS characteristics element is segmented to include multiple quality tiers, each with its own QoS parameters. This allows the protocol to handle multiple quality levels (e.g., different resolutions, frame rates, audio codecs) within a single flow, resolving the contradiction between simplicity and adaptability by organizing complexity in a structured, manageable way
Solution Approach 2:
The QoS characteristics element is designed to be universal by supporting both single-tier and multi-tier QoS configurations. The element can adapt its structure based on whether one or multiple quality tiers are needed, making the protocol versatile enough to handle both simple and complex application requirements without requiring separate protocols
2Adaptability or versatility
If multiple QoS tiers are signaled for the same flow, then the network can better balance the needs of different flows and accommodate varying application demands, but the signaling overhead and protocol complexity increase
Solution Approach 1:
Multiple QoS tiers are merged into a single QoS characteristics element rather than requiring separate elements for each tier. This consolidation reduces signaling overhead by encoding multiple quality level specifications in one structured data element, allowing the network to balance different flow needs without proportionally increasing signaling traffic
Solution Approach 2:
The protocol uses parameter changes within the QoS characteristics element to indicate different quality tiers. By modifying specific parameters (such as quality tier indicators, resolution levels, frame rate specifications) within the same element structure, the protocol can signal multiple QoS levels efficiently without requiring complete re-signaling of all parameters

AI summary
Techniques for modifying quality of service (QOS) for wireless communication. These techniques include identifying a plurality of QoS levels for an application flow between a wireless access point (AP) and a wireless station (STA), each of the QoS levels defining a plurality of QoS characteristics for the application flow. The techniques further include establishing a first QoS level, of the plurality of QoS levels, for the application flow, based on the identified plurality of QoS levels. The techniques further include modifying the QoS level for the application flow from the first QoS level to a second QoS level, of the plurality of QoS levels, based on selecting between the identified plurality of QoS levels.
