Solution Overview

Problem

Manual operations in existing methods for migrating ADSL/2/2+ services to VDSL2 are inefficient, leading to increased maintenance costs, service disruptions, and the need for extensive human intervention, which hampers the seamless transition and scalability of broadband services.

Innovation Solution

A method that automates the migration process by monitoring the VDSL2 port in Backward Compatibility mode, synchronizing the modem with the access multiplexer, and using specific identification parameters to verify and configure the modem, allowing for automatic switching to VDSL2 mode without manual intervention, utilizing protocols like SNMP and TL-1 for communication and configuration changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual operations are used for migrating ADSL/2/2+ services to VDSL2, then service migration can be performed, but maintenance costs increase and service disruptions occur

Engineering Contradiction:
Improveservice continuityVSAvoidmigration efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs automatic self-service migration by detecting modem identification parameters, verifying modem types, and changing port configurations without human intervention. The access multiplexer automatically retrieves modem parameters, verifies compatibility, and executes configuration changes, eliminating the need for manual operator intervention while maintaining service reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring modem identification parameters and transmission modes. The access multiplexer retrieves modem parameters, verifies them against required specifications, and uses this feedback information to automatically adjust port configurations and execute migration decisions based on real-time system state.

Inventive Principle:
Principle #23Feedback

2Extent of automation

If manual configuration changes are performed, then migration decisions can be made based on parameter verification, but extensive human intervention is required

Engineering Contradiction:
Improvemigration automationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The access multiplexer automatically performs configuration changes by retrieving modem identification parameters, verifying modem types, and executing port configuration modifications without human intervention. The system self-manages the entire migration process including parameter verification and configuration execution.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The access multiplexer serves multiple functions: it acts as a modem for communication with subscriber modems, a management system for retrieving and verifying modem parameters, and a configuration system for executing port configuration changes. This multi-functionality consolidates what would otherwise require separate systems into a single integrated device.

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

3Ease of operation

If existing management systems are used for migration, then parameter-based migration is possible, but operations must be performed manually

Engineering Contradiction:
Improveoperation simplicityVSAvoidmigration time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically executes migration operations by detecting modem parameters and executing configuration changes without requiring manual operator actions. The access multiplexer autonomously retrieves modem identification parameters, verifies compatibility, and performs configuration changes, eliminating manual operational steps.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary verification of modem identification parameters before executing migration. By pre-checking modem types and compatibility requirements, the system prepares migration decisions in advance, enabling automatic execution without manual intervention during the actual migration process.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a method for migrating VHBB services from ADSL/2/2+ technique to VDSL2 technique, with the use of management system. The server which monitors identification parameters verifies the type of modem and transmits, to the management system, a request to change configuration, and the system reconfigures VDSL2 port by leaving Backward Compatibility mode.
