Solution Overview

Problem

Existing methods for migrating VHBB services from ADSL/2/2+ to VDSL2 techniques are inefficient and require manual intervention, leading to increased maintenance costs, service disruptions, and complexity in managing network hardware.

Innovation Solution

A method that automates the migration process by monitoring the VDSL2 port with a server, synchronizing the modem with the access multiplexer, and using specific identification parameters to verify and switch the modem type, allowing seamless transition from ADSL/2/2+ to VDSL2 mode without manual intervention, utilizing communication protocols like SNMP and EoC.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual migration method is used, then service migration can be performed, but maintenance costs increase and service downtime increases

Engineering Contradiction:

Improvemigration automationVSAvoidservice downtime

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs self-service by automatically detecting modem type changes and triggering migration procedures without human intervention. The server monitors modem identification parameters, verifies modem type changes, and executes port configuration changes autonomously, eliminating the need for manual operator intervention and reducing service downtime.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring modem identification parameters and automatically responding to detected changes. When a modem type change is detected, the system receives feedback about the change, verifies it through parameter comparison, and triggers appropriate migration actions, creating a closed-loop control system that reduces manual intervention.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If manual migration method is used, then service migration can be performed, but device complexity increases

Engineering Contradiction:

Improvemigration operationVSAvoidhardware management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The server acts as an intermediary between the modem and access multiplexer, automatically managing the complex migration process. It monitors modem parameters, verifies changes, and coordinates configuration updates, simplifying the operation for network operators while handling the complexity of hardware management and protocol coordination in the background.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If automated monitoring is implemented, then migration speed increases, but system complexity increases

Engineering Contradiction:

Improvemigration speedVSAvoidsystem architecture

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The server implements multi-functionality by combining monitoring, detection, verification, and migration execution functions in a single system. It simultaneously performs parameter monitoring, modem type verification, and automated migration orchestration, reducing the need for separate dedicated systems and managing complexity through functional integration rather than multiplication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a method for migrating VHBB services from ADSL/2/2+ technique to VDSL2 technique, in which ADSL/2/2+ modem, connected to VDSL2 port in BC mode, is replaced with VDSL2 modem. The server which monitors identification parameters verifies the type of modem and changes the operating mode of VDSL2 port by leaving Backward Compatibility mode.
