Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network devices face challenges in providing optimal Giga Internet services due to interference and misconnection issues caused by varying cable characteristics, line lengths, and simultaneous usage in bundled access networks, leading to suboptimal communication service quality.
Innovation Solution
A network management apparatus that distinguishes direct signals from interference signals by analyzing signal strength and channel frequency response, selecting the best-connected lines, and establishing links with customer premises equipment using a unique frequency, thereby minimizing interference and ensuring optimal link establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a bundle of wiring is used to connect customer premises equipment in dense buildings, then the network can serve multiple subscribers through a main distribution frame, but interference signals (crosstalk) between adjacent lines cause misconnection to adjacent ports or modems
Solution Approach 1:
The patent applies preliminary action by performing channel estimation and signal analysis before final link establishment. The network management apparatus pre-analyzes registration response signals to identify direct signals versus interference signals, and determines the optimal port-customer premises equipment correspondence in advance before establishing the actual communication link. This prevents misconnection caused by crosstalk in bundled wiring environments.
2Ease of operation
If link establishment is performed without distinguishing direct signals from interference signals, then the process is simple, but the initial link may be incorrectly established with suboptimal modems resulting in low service quality
Solution Approach 1:
The patent replaces simple signal detection with advanced signal processing techniques. Instead of relying on basic connection attempts, the system uses channel frequency response analysis and signal strength measurement to automatically distinguish direct signals from interference signals. This substitution of mechanical/simple operations with sophisticated signal processing enables accurate link establishment while maintaining operational simplicity through automation.
3Power
If large transmission power or channel bandwidth is allocated to a specific cable, then that cable can provide better service, but it acts as interference for adjacent cables resulting in quality problems
Solution Approach 1:
The patent implements feedback through channel estimation and signal quality monitoring. The network management apparatus continuously analyzes registration response signals and channel frequency responses to detect interference conditions. Based on this feedback, the system can identify when a cable is causing excessive interference to adjacent cables and adjust port assignments or transmission parameters to mitigate the harmful effects, ensuring optimal service quality for all subscribers in the bundled wiring environment.
