DSL Connection Profile Selection via Customer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DSL connection management systems fail to effectively identify and cater to different customer segments with varying requirements, leading to suboptimal trade-offs between data rate and stability in xDSL connections.
Innovation Solution
A method and device that automatically select a DSL connection profile based on predefined usage profiles, using a controlling device to analyze stored parameter values and adjust parameters such as data rate, power spectral density, and error correction to match specific customer segment requirements, optimizing bandwidth, stability, and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a higher data rate is configured for a DSL connection, then the bandwidth is improved, but the stability of the connection deteriorates
Solution Approach 1:
The invention segments DSL connections into different customer segments (e.g., residential, business, gaming, VoIP) based on their specific requirements. Each segment is assigned appropriate connection parameters that optimize both data rate and stability for that particular segment, rather than using a single configuration for all connections.
Solution Approach 2:
The invention applies local quality by configuring different parameter sets (bit loading, FEC, interleaving) tailored to specific local conditions of each customer segment. Each segment receives customized parameters that match its specific needs, allowing high data rates for segments that prioritize speed while maintaining stability for segments that prioritize reliability.
2Device complexity
If a single DSL connection profile is used for all connections, then the device complexity is reduced, but the adaptability to different customer requirements deteriorates
Solution Approach 1:
The invention creates a universal customer segment identification mechanism that can handle multiple customer types and requirements through a single standardized approach. The system identifies customer segments and applies appropriate profiles, making the system adaptable to various needs while maintaining manageable complexity through automation.
Solution Approach 2:
The system automatically identifies customer segments and selects appropriate connection profiles without requiring manual configuration. The automated identification and profile selection processes enable the system to serve diverse customer segments independently, reducing the need for complex manual management while maintaining high adaptability.

AI summary
As an improved or alternative way for selection of operating parameters of individual xDSL connections, the invention proposes a method of selecting a DSL connection profile for a DSL connection (201, 202) by a controlling device (100), comprising the steps of a) storing (510, 610) parameter values of predefined parameters associated with the DSL connection (201, 202) in at least one storage unit (330), b) selecting (520, 620), by the controlling device (100), at least one DSL usage profile from a number of predefined DSL usage profiles as a matching DSL usage profile depending on the stored parameter values, wherein the at least one matching usage profile matches the stored parameter values, c) selecting (530, 630), by the controlling device (100), a DSL connection profile for the DSL connection (201, 202) from a number of predefined DSL connection profiles depending on the selected at least one DSL usage profile, and d) operating (540, 640) the DSL connection (201, 202), wherein connection parameters of the DSL connection (201, 202) are controlled using the selected DSL connection profile. Further, the invention is directed to a controlling device and a system for performing the method.
