Solution Overview

Problem

Current methods for configuring ADSL terminal parameters are either unstable due to the need for continuous network management server availability or complicated due to varying DSLAM command formats and maintenance interfaces, leading to difficulties in operation and maintenance.

Innovation Solution

A method where network management sends configuration parameters to a DSLAM, which converts and stores them for the ADSL terminal to download, allowing the terminal to request parameters upon startup or operation, simplifying the process and reducing network involvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the network management server continuously monitors and responds to terminal configuration requests, then the terminal can acquire configuration parameters, but the system stability deteriorates when the server is unavailable

Engineering Contradiction:
Improveterminal configuration acquisitionVSAvoidsystem stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The DSLAM pre-stores terminal configuration parameters locally before being needed. When a terminal requests configuration, the DSLAM can immediately provide the parameters from its local storage without requiring real-time connection to the network management server, thus ensuring system reliability while maintaining ease of operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The DSLAM acts as an intermediary between the network management server and the terminal. It receives configuration parameters from the server and stores them locally, then serves as a local configuration source for terminals, reducing direct dependency on the server and improving system stability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If different DSLAMs maintain configuration parameters locally with their own command formats, then terminal configuration can be performed locally, but maintenance complexity increases

Engineering Contradiction:
Improvelocal configuration capabilityVSAvoidmaintenance complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The DSLAM is designed with a universal configuration management capability that can serve multiple terminals with different types using a standardized local storage format. This allows local configuration capability while maintaining uniform interfaces that simplify maintenance across different DSLAM devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If configuration parameters are stored centrally at the network management server, then centralized control is achieved, but operational complexity increases due to multiple device involvement

Engineering Contradiction:
Improvecentralized controlVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The configuration management function is segmented into two parts: centralized parameter generation at the network management server and localized parameter storage at the DSLAM. This segmentation allows centralized control for adaptability while local execution reduces operational complexity by eliminating the need for multiple devices to be involved in each configuration operation

Inventive Principle:
Principle #1Segmentation

AI summary

This invention relates to access technologies in the communication field and discloses a method for configuring parameters of a broadband access terminal, which is stable, simple in operation, convenient in maintenance and easy to implement. Configuration parameters are generated at the network management side and are sent to a DSLAM, the DSLAM stores the configuration parameters, and a terminal downloads the configuration parameters through interacting with the DSLAM. In addition, the terminal can request for download upon start-up or in operation, and the download can be implemented by the terminal or the DSLAM.
