Wireless LAN QoS Management Table Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complex operations and manual QoS setting challenges when connecting to various wireless LAN environments, including homes, offices, and public hotspots, as existing techniques do not efficiently manage QoS settings across different networks and require manual configuration, lacking automatic management of QoS and security settings.
Innovation Solution
A wireless LAN system with a communication terminal and LAN control apparatus that exchanges QoS management tables to automatically set and update QoS settings, allowing terminals to request and analyze QoS policies, and distribute updated settings to all connected devices, enabling seamless QoS control across different networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual QoS setting is performed for each LAN environment, then QoS control can be implemented, but the operation becomes complicated and time-consuming
Solution Approach 1:
The terminal device automatically obtains QoS management tables from access points and performs self-configuration of QoS parameters without user intervention. The system enables automatic QoS setting by having the terminal request and process QoS management information from the network side, eliminating manual configuration requirements while maintaining reliable QoS control.
2Reliability
If QoS settings are manually configured for each LAN, then QoS policy can be established, but the process becomes troublesome especially when moving between different LANs
Solution Approach 1:
QoS management tables are pre-configured in access points for different LAN environments. When a terminal connects to an access point, it automatically requests and obtains the appropriate pre-prepared QoS management table, eliminating the need for users to manually configure QoS settings when moving between different LANs such as home, office, and public hotspots.
3Ease of operation
If automatic QoS management is implemented, then operation is simplified, but compatibility with existing LAN control apparatus must be ensured
Solution Approach 1:
The system maintains compatibility with existing LAN control apparatus by using standard IEEE 802.11 communication protocols while adding universal QoS management table exchange functionality. The terminal device can operate in both automatic QoS management mode and traditional manual configuration mode, ensuring broad compatibility across different network environments and devices.

AI summary
Disclosed is a wireless LAN (Local Area Network) system which overcomes a troublesome operation and process of setting QoS needed for each LAN at the time of using various LANs in a home, an office, countless Hotspots and so forth. The wireless LAN system has a terminal and LAN control section. The terminal has a QoS (Quality of Service) analyzing/setting section which requests of the LAN control section for a QoS management table as a QoS policy to manage QoS of communication data at the time of establishing connection to a wireless LAN, analyzes the table sent from the LAN control section in response to the request, sets QoS setting data based on the result of that analysis, and sends the data to the LAN control section. The LAN control section has a QoS setting DB (Data Base) which holds the table in an updatable manner, and a QoS communication control section which sends the table in response to the request from the terminal, updates the QoS setting data from the communication terminal on the table, and executes QoS control on the communication data with the communication terminal in accordance with the QoS policy.
