Virtual Wireless Channel Routing for Secondary Network QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network architectures based on WiFi or WiMax standards fail to guarantee a sufficient quality of service for data transmission between a primary and a secondary network, especially when the secondary network's transmission capacities are lower than those of the primary network, leading to unreliable communication, particularly for applications like video transmission.
Innovation Solution
The creation of virtual wireless channels with configurable parameters, specifically point-to-point links between a base station and remote stations in the secondary network, ensures guaranteed quality of service by routing data through these channels, which are managed using protocols like IEEE 802.16, and includes steps for identifying data recipients, verifying available bitrate, and authorizing or rejecting transmissions based on sufficient bitrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared wireless medium is used for communication between primary and secondary networks, then the device complexity is reduced and ease of operation is improved, but the quality of service cannot be guaranteed when transmission capacities are mismatched
Solution Approach 1:
The shared wireless medium is segmented into multiple virtual channels, each dedicated to specific point-to-point links between base station and remote stations. This segmentation allows independent quality of service management for each channel while maintaining the simplicity of a single physical medium, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
Virtual channels act as intermediaries between the primary and secondary networks, providing a layer of abstraction that enables quality of service guarantee without requiring complex changes to the underlying physical infrastructure. The virtual channel layer mediates resource allocation and traffic management, ensuring reliable communication while keeping the network architecture relatively simple.
2Reliability
If virtual wireless channels with configurable parameters are created for each point-to-point link, then the quality of service is guaranteed, but the device complexity increases
Solution Approach 1:
The base station implements a universal virtual channel management mechanism that handles multiple virtual channels through a standardized process. This multi-functional approach allows the same management logic to be applied across all virtual channels, reducing the effective complexity despite the presence of multiple configured channels. The system provides quality of service guarantee through this universal management framework.
3Reliability
If the secondary network uses standard WiFi or WiMax protocols, then the ease of manufacture and adaptability are improved, but the quality of service for applications like video transmission cannot be ensured
Solution Approach 1:
The invention changes the parameters of the communication protocol by introducing configurable virtual channel parameters such as bandwidth allocation, priority levels, and quality of service metrics. This allows the system to adapt standard WiFi or WiMax protocols to provide guaranteed quality of service for real-time applications like video transmission, while maintaining compatibility with existing standards through parameter configuration rather than fundamental protocol changes.

AI summary
Communication method between a primary network (110) and a secondary network (24), the secondary network comprising a plurality of remote stations (210 to 230) and having transmission capacities lower than the transmission capacities of the primary network, a base station (20) enabling data transmissions between the primary and secondary networks. In order to guarantee a quality of service, the method comprises: - a creation of at least one virtual wireless channel (21 to 23), associated with the secondary network with configurable channel parameters, and - a routing of the data that transits by said base station to be transmitted to the secondary network according to the virtual channel or channels created. each virtual channel enabling a point-to-point link between the base station and a station of said plurality.
