Radio LAN Base Station Tunnel Segmentation for Control Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems face challenges in applying path control and Quality of Service (QoS) within a single data tunnel between AP control apparatus and wireless LAN base station apparatus, leading to congestion and instability in communication systems.
Innovation Solution
The system forms multiple data tunnels and uses different tunnels based on the type of transmission data, separating control frames and data frames to ensure reliable communication and improve stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control frames and data frames are transmitted through the same data tunnel, then device complexity is reduced, but communication reliability deteriorates due to congestion and inability to apply QoS
Solution Approach 1:
The patent segments the single data tunnel into multiple tunnels based on frame types. Control frames are transmitted through a dedicated control tunnel, while data frames use separate data tunnels. This segmentation allows independent QoS management and path control for each tunnel type, ensuring control frame reliability while maintaining manageable system complexity through structured organization.
2Ease of operation
If a single data tunnel is used for all transmissions, then ease of operation is improved, but productivity deteriorates due to congestion affecting control frame delivery
Solution Approach 1:
The system segments traffic into control and data planes with separate tunnels. Control frames use a dedicated tunnel with guaranteed delivery, while data frames use separate tunnels that can be managed independently. This segmentation improves productivity by ensuring control frames are never delayed by data traffic congestion, while ease of operation is maintained through automated tunnel management and clear separation of concerns.
Solution Approach 2:
The patent introduces an intermediary mechanism (the tunnel formation management section) that automatically manages multiple tunnels based on frame type. This intermediary handles the complexity of tunnel selection and management, presenting a simplified interface to upper layers while ensuring efficient control frame delivery through dedicated pathways.
3Device complexity
If path control and QoS are applied to a single data tunnel, then device complexity is reduced, but adaptability deteriorates due to inability to differentiate control and data traffic requirements
Solution Approach 1:
The patent segments the network into distinct tunnels for control and data traffic. Each tunnel type can have its own QoS parameters and path control settings. This segmentation provides adaptability by allowing different QoS policies for control frames (high priority, guaranteed delivery) versus data frames (best effort or configurable), while keeping device complexity manageable through standardized tunnel management procedures.
Solution Approach 2:
The system applies local quality by configuring QoS parameters specific to each tunnel type. Control tunnels receive special QoS treatment with higher priorities and guaranteed bandwidth, while data tunnels can be configured with appropriate QoS based on application requirements. This local quality approach enables frame-specific path control without requiring complex global QoS management.

AI summary
There are provided a communication system, a radio LAN base station control device, and a radio LAN base station device capable of increasing the control reliability and improving communication stability and safety between the radio LAN base station control device and the radio LAN base station device. In this communication system (10), a plurality of data tunnels are formed between an AP control device (100) and the radio LAN base station device (200) and the data tunnels are used according to the frame type (control data frame, data frame, etc.) so as to increase the reliability that the AP control frame reaches the radio LAN base station device (200). As a result, control reliability between the AP control device (100) and the radio LAN base station device (200) is increased. Thus, it is possible to improve the communication stability and safety in the communication system (10).
