DSL Router Auto-Authentication via Line Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DSL user authentication methods require user interaction, leading to potential errors and increased effort for both users and providers, as they need to manually input authentication data and configure settings.
Innovation Solution
An automatic authentication method where a line identifier or hardware identifier is transmitted to the authentication unit, enabling auto-configuration of DSL routers and connected components, such as WLAN or VoIP systems, without user intervention, allowing for configuration updates and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual authentication and configuration is used, then user control and customization are improved, but user effort and potential for errors increase
Solution Approach 1:
The system performs self-service authentication by automatically transmitting the identifier from the DSL router through the DSLAM to the authentication unit without requiring user intervention. The DSL router autonomously participates in the authentication process, eliminating the need for manual user input while maintaining secure access control.
Solution Approach 2:
The identifier is pre-configured in the DSL router before authentication is needed. This preliminary preparation allows the authentication process to proceed automatically without requiring user input at the moment of authentication, thereby reducing user effort while maintaining security.
2Ease of operation
If automatic authentication is implemented, then user effort is reduced, but system complexity increases
Solution Approach 1:
The DSLAM serves as an intermediary component that facilitates automatic authentication by relaying the identifier from the DSL router to the authentication unit. This intermediary approach distributes system complexity across existing infrastructure components rather than concentrating it in a single complex module, making the overall system more manageable.
Solution Approach 2:
The authentication mechanism leverages existing multi-functional components in the DSL infrastructure (DSL router, DSLAM, authentication unit) that already perform multiple functions. By repurposing these existing components for authentication rather than adding dedicated new hardware, the system achieves automatic authentication without proportionally increasing overall system complexity.
3Manufacturing precision
If manual configuration is required, then configuration accuracy is improved, but setup time and user frustration increase
Solution Approach 1:
The DSL router autonomously performs configuration tasks by automatically transmitting its identifier and receiving authentication results without requiring user input. This self-service approach eliminates configuration errors caused by manual user input while maintaining the precision needed for proper system setup.
Solution Approach 2:
The authentication unit provides feedback to the DSL router regarding authentication success or failure. This automated feedback mechanism ensures configuration accuracy by immediately identifying and correcting issues without requiring user interpretation or manual adjustment, thereby reducing both setup time and configuration errors.
4Ease of operation
If user interaction is eliminated, then ease of setup is improved, but ability to handle unique user cases deteriorates
Solution Approach 1:
The system accommodates unique user cases by allowing the identifier parameter to vary between different DSL routers and configurations. The automatic authentication mechanism remains general while adapting to specific user needs through parameter variation, maintaining both simplicity and versatility.

AI summary
The invention relates to a method for authenticating a DSL user, where an identifier identifying the connection to the DSL router is automatically transmitted, for the purpose of authentication, to an authentication unit in which the identifier is taken as a basis for authenticating the user, and an auto-configuration unit is used or can be used for automatically configuring the DSL router, and/or components connected to it, via the connection to the DSL router.
