Dynamic QoS Provisioning for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QoS implementations in wireless networks, such as those governed by 802.11 standards, lack dynamic assignment of QoS parameters, leading to static provisioning that does not accurately reflect the real-time needs of devices, potentially causing quality issues for applications requiring high priority access.
Innovation Solution
A technique for dynamically provisioning QoS parameters during authentication, allowing for per-client configuration of QoS features, which includes verifying if applications require high priority access before granting access to corresponding queues, ensuring that devices with high priority needs, like softphones, receive priority over those that do not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static QoS provisioning is used, then network configuration is simple, but QoS parameters do not reflect real-time device needs
Solution Approach 1:
The patent implements dynamic QoS provisioning by transitioning from static configuration to dynamic assignment during authentication. The system evaluates client devices in real-time and assigns QoS parameters dynamically based on detected application requirements, enabling the network to adapt to changing traffic needs while maintaining manageable complexity through automated decision-making.
2Reliability
If dynamic QoS assignment is implemented, then QoS quality improves, but authentication process complexity increases
Solution Approach 1:
The patent performs QoS parameter assignment during the authentication process itself, rather than requiring separate configuration steps. By incorporating QoS evaluation and assignment into the existing authentication flow, the system achieves reliable QoS delivery without adding significant complexity to the overall authentication procedure.
Solution Approach 2:
The system automatically detects application requirements and assigns appropriate QoS parameters without manual intervention. The authentication server evaluates client needs and autonomously determines QoS parameters, reducing the operational burden on network administrators while ensuring reliable QoS for priority applications.
3Ease of operation
If high priority access is granted to all clients, then ease of operation improves, but network resource efficiency decreases
Solution Approach 1:
The patent applies different QoS treatment to different client devices based on their specific needs. Rather than uniform high priority access for all clients, the system assigns high priority only to devices with priority applications (such as voice or video), while maintaining normal service for other traffic types. This localized quality differentiation ensures network resource efficiency while preserving ease of operation for critical applications.

AI summary
A technique for improving quality of service involves dynamically provisioning quality of service parameters. An example according to this technique is a system including a server and an access point. The server provisions quality of service parameters restricting the station's transmission of data through the access point to one or more access classes of varying priority.
