VLAN-QoS Mapping for Wireless Network Link Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless user devices often experience insufficient Quality-of-Service (QoS) when accessing the internet due to bandwidth and power limitations in wireless communication networks and Local Area Networks (LANs, which are not efficiently controlled to meet the specific needs of different types of user devices.
Innovation Solution
A wireless communication device determines Quality-of-Service (QoS) levels for wireless network links and associates them with Virtual Local Area Networks (VLANs), indicating these QoS levels to user devices and exchanging user data over VLANs using the associated QoS levels, thereby ensuring sufficient QoS despite network limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless user devices access the internet over wireless communication networks and LANs, then data connectivity is provided, but insufficient Quality-of-Service (QoS) is experienced due to bandwidth and power limitations
Solution Approach 1:
The patent segments the network traffic into different Virtual LANs (VLANs) based on QoS requirements. Each VLAN is assigned specific QoS levels, allowing high-priority traffic to be separated from low-priority traffic. This segmentation enables differential QoS handling despite overall bandwidth limitations, as critical applications receive guaranteed service levels while non-critical traffic uses remaining capacity.
Solution Approach 2:
The patent applies local quality by assigning different QoS characteristics to different VLANs and their corresponding wireless network links. Each VLAN can have customized QoS parameters (throughput, latency, reliability) matched to its specific requirements. This allows high-priority applications to receive enhanced local quality metrics even when overall network bandwidth is constrained.
2Ease of operation
If QoS levels are controlled for VLANs and wireless communication networks, then network management is improved, but the specific needs of different types of user devices are not effectively served
Solution Approach 1:
The patent creates a universal QoS mapping framework that works across multiple device types and network configurations. The system provides a standardized interface for defining QoS levels and VLAN associations that can accommodate diverse user devices (smartphones, tablets, laptops, IoT devices) with different requirements. This universal approach simplifies operation while maintaining adaptability through flexible VLAN-QoS mapping rules.
Solution Approach 2:
The patent enables parameter changes by allowing dynamic adjustment of QoS levels and their association with different VLANs based on device type and application requirements. The system can modify throughput, latency, and reliability parameters for specific VLANs to match the needs of different user devices. This flexibility allows the same QoS control mechanism to serve diverse device-specific needs without requiring separate control systems.
3Use of energy by moving object
If bandwidth and power limitations are imposed on user devices by wireless communication networks, then network resources are conserved, but sufficient QoS cannot be achieved
Solution Approach 1:
The patent applies dynamics by enabling flexible, adaptive QoS allocation that responds to changing network conditions and device requirements. Rather than imposing fixed bandwidth and power limitations, the system dynamically adjusts QoS levels for different VLANs based on current network capacity, device needs, and application priorities. This dynamic approach allows the network to conserve resources during low-demand periods while ensuring sufficient QoS during high-priority transmissions.

AI summary
A wireless communication device determines QoS levels for wireless network links. The wireless communication device associates the QoS levels for the wireless network links with a Virtual Local Area Network (VLAN). The wireless communication device indicates to a user communication device the association of the QoS levels for the wireless network links with the VLAN. The wireless communication device exchanges the user data with the user communication device over the VLAN using the QoS levels for the wireless network links that are associated with the VLAN. The wireless communication device wirelessly exchanges the user data over the wireless network links using the QoS levels for the wireless network links.
