WLAN QoS Parameter Configuration via Unicast Beacon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WLAN systems cannot dynamically adjust QoS parameter sets on a per terminal basis, leading to low data transmission efficiency and poor user experience.
Innovation Solution
A method and system where a network device sends a default QoS parameter set to a terminal and then modifies it using a unicast beacon frame or active probe response frame, allowing for dynamic adjustment of QoS parameters based on the terminal's specific requirements, such as access category and priority of data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a network device uses a default QoS parameter set for all terminals, then the configuration process is simple and uniform, but data transmission efficiency and user experience deteriorate due to inability to dynamically adjust parameters per terminal
Solution Approach 1:
The patent applies local quality by transitioning from a uniform default QoS parameter set applied to all terminals to terminal-specific customized QoS parameter sets. The network device determines each terminal's access category based on data packet priorities and protocols, then assigns tailored QoS parameters (such as contention window sizes, transmission opportunity limits) specific to that terminal's needs, thereby optimizing data transmission efficiency for each terminal individually while maintaining configuration manageability through automated determination rules.
2Ease of operation
If a network device cannot dynamically adjust QoS parameter sets on a per terminal basis, then the system operation is simple, but user experience and data transmission efficiency worsen
Solution Approach 1:
The patent implements self-service by enabling the network device to automatically determine each terminal's access category and generate appropriate QoS parameter sets without manual intervention. The system autonomously monitors data packet characteristics, applies predetermined determination rules to classify access categories, and dynamically adjusts QoS parameters for each terminal based on real-time network conditions and terminal requirements, thereby maintaining operational simplicity while significantly improving user experience quality through automated adaptive optimization.
3Productivity
If a network device sends customized QoS parameter sets to each terminal, then data transmission efficiency and user experience improve, but the complexity of parameter management increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting QoS parameter values based on terminal-specific access categories. The network device modifies key parameters such as minimum and maximum contention window sizes, transmission opportunity limits, and interframe space values according to each terminal's determined access category. These parameter changes are automated through predetermined determination rules that map data packet characteristics to appropriate QoS parameter configurations, thereby achieving optimized data transmission efficiency while managing complexity through systematic parameter adjustment protocols.

AI summary
A method, an apparatus, and a system for quality of service (QoS) parameter configuration in a wireless local area network (WLAN), where the method includes sending, by a network device, a default first QoS parameter set to a terminal, sending, by the network device, a QoS parameter set modification message including a second QoS parameter set to the terminal, where the second QoS parameter set is different from the first QoS parameter set, and the QoS parameter set modification message is a unicast beacon frame or an active probe response frame. In this way, the second QoS parameter set different from the first QoS parameter set is sent to the terminal using the unicast beacon frame or the active probe response frame, which ensures that the network device dynamically adjusts a QoS parameter set of the terminal on a per terminal basis, thereby improving data transmission efficiency and user experience.
