Wireless LAN QoS Control via Authentication Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoS control technologies in wireless LAN networks lack versatility and do not provide consistent QoS services across different terminals, as they require special user information in data packets and focus primarily on IP network QoS control, neglecting QoS control between wireless LAN access points and terminals.
Innovation Solution
A system that includes a wireless LAN base station and terminal capable of receiving authentication and QoS service information from a server, allowing for priority control based on user authentication and stored user information, ensuring consistent QoS service across different terminals by using an authentication server and a policy server to manage and notify QoS settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special user information is added into data packets for QoS control, then QoS service can be offered for each terminal, but versatility is reduced and QoS control cannot be maintained across different terminals
Solution Approach 1:
The patent introduces a server as an intermediary component that stores user information and QoS policies separately from the data packets. The server acts as a mediator between terminals and the QoS control mechanism, providing user identification information and QoS parameters without requiring special fields in the data packets themselves. This resolves the contradiction by maintaining QoS service consistency through the server while preserving terminal compatibility.
Solution Approach 2:
The patent extracts user identification and QoS control information from the data packets and stores them separately in a server database. By taking out these elements from the packet structure, the system maintains standard packet formats for compatibility while enabling consistent QoS control through external server-based user information management.
2Reliability
If QoS control is implemented within IP network only, then IP network QoS can be managed, but QoS control between wireless LAN access point and terminal is not addressed
Solution Approach 1:
The patent creates a universal QoS control system that functions across multiple network types (wireless LAN and IP network). The server-based architecture provides multi-functionality by handling user authentication, QoS policy management, and priority control in a unified manner that works regardless of whether the terminal is connected via wireless LAN or IP network, thus expanding network scope while maintaining reliable QoS control.
3Ease of operation
If QoS service is offered for each terminal individually, then terminal-specific control is achieved, but service consistency across different terminals for the same user cannot be ensured
Solution Approach 1:
The server serves as an intermediary that links terminal-specific operations with user-level consistency. When a terminal connects, the server identifies the user and retrieves the appropriate QoS policy, ensuring that the same user receives consistent service across different terminals while still allowing terminal-specific control mechanisms to operate.
Solution Approach 2:
The system changes the parameter of QoS control from terminal-based to user-based by using user identification information stored in the server. This parameter change enables the system to maintain terminal-specific control capabilities while ensuring service consistency by applying QoS policies based on user identity rather than terminal identity.

AI summary
In the QoS control system of the wireless LAN network including the wireless LAN access points, and the wireless LAN terminals to be connected thereto, the wireless LAN access point authenticates the user on the basis of the recorded user's authentication information when the user carries out the authentication request from the wireless LAN terminal. The wireless LAN access point is connected to the servers to notify the wireless LAN access point of the information for identifying the wireless LAN terminal and the recorded user's QoS service content through the communication network. The wireless LAN access point and the wireless LAN terminal carry out the priority control in accordance with the priority information of the QoS service from the server. Even when the terminal to be used is changed, if the same user logs onto the certificate server by using the same authentication information, the same QoS service can be offered consistently.
