DSL Line Stability via Dynamic MIB Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Dynamic Line Management (DLM) systems cannot effectively improve DSL line stability due to the lack of support for dynamically updating Forward Error Correction (FEC) capabilities with bit error ratios, as R and N parameters are not standard Management Information Base (MIB) parameters and thus not open to third-party adjustments.
Innovation Solution
A method and apparatus that collect, analyze, and adjust MIB parameters to determine an Operating Performance Value (OPV) and adjust Management Information Base (MIB) parameters when the OPV is below a Target Performance Value (TPV), using standard MIB parameters to enhance line stability by increasing the error correction capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ratio of R and N parameters in FEC code words is adjusted to improve line stability, then error correction capability is enhanced, but the adjustment is infeasible because R and N are not standard MIB parameters and not open to third-party applications
Solution Approach 1:
The patent changes the parameter representation from non-standard R and N values to standard MIB parameters (specifically adslLoopParamsErrorCorrectionCapability). This allows the error correction capability to be adjusted through standardized interfaces while maintaining the same functional effect, resolving the contradiction between reliability improvement and operational ease.
2Adaptability or versatility
If DLM systems use non-standard parameters for dynamic adjustment, then error correction can be updated adaptively, but the system complexity increases and compatibility with standard management interfaces is reduced
Solution Approach 1:
The patent makes the error correction capability adjustment universal by implementing it through standard MIB parameters that can be accessed by any third-party application using standard SNMP interfaces. This single standardized approach serves multiple functions: dynamic adaptation, standard compliance, and broad applicability, thereby reducing system complexity while maintaining adaptability.
3Ease of operation
If standard MIB parameters are used for adjustment, then compatibility and ease of operation are improved, but the ability to dynamically update error correction capability with bit error ratio is lost
Solution Approach 1:
The patent implements a feedback mechanism where the DLM system continuously monitors bit error ratios and automatically adjusts the adslLoopParamsErrorCorrectionCapability MIB parameter in response. This closed-loop feedback enables dynamic updates using standard parameters, simultaneously achieving ease of operation through standard interfaces and adaptability through real-time response to error conditions.

AI summary
A method for improving line stability, an adjusting apparatus and a system are provided. The method includes determining an Operating Performance Value (OPV) on a current Digital Subscriber Line (DSL); and if the OPV is below a preset Target Performance Value (TPV), adjusting Management Information Base (MIB) parameters in a line template. The apparatus includes a determining unit and an adjusting unit. With the provided method, apparatus, and system, the error correction capability of the DSL line can be updated with the actual bit error ratio to adapt to a complex environment and to improve the line stability.
