Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In communication service provider networks, it is difficult to flexibly change communication bands when a subscriber terminal transitions from one CPE to another, as existing methods require manual adjustments in transfer apparatus settings, which are inflexible and time-consuming.

Innovation Solution

A communication system with first and second virtual CPEs that include band acquisition and control units to dynamically adjust communication bands by subtracting or adding values from contract bands when a subscriber terminal transitions, allowing for seamless band management without requiring changes in transfer apparatus settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication band is set for each subscriber in line connection, then service provision is established, but flexibility to change communication band when subscriber terminal transitions between CPEs is poor

Engineering Contradiction:

Improveflexibility to change communication bandVSAvoidtime to change communication band

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic communication band allocation by enabling real-time detection of subscriber terminal transitions between CPEs and automatically adjusting band settings through virtual CPE coordination, replacing static per-subscriber band assignment with a flexible, event-driven band management system

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes feedback mechanisms where virtual CPEs monitor subscriber terminal connections and communicate transition events to trigger automatic band reallocation, creating a closed-loop control system that continuously adapts band settings based on actual network conditions and subscriber movements

Inventive Principle:

Principle #23Feedback

2Ease of operation

If manual adjustment of transfer apparatus settings is used, then communication band can be changed, but the process is time-consuming and inflexible

Engineering Contradiction:

Improveease of band adjustmentVSAvoidtime for manual adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system enables self-service band management where the network automatically detects subscriber terminal transitions and performs band reallocation without human intervention, with virtual CPEs autonomously coordinating band changes based on detected connection events and subscriber movements

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment of transfer apparatus settings with automated electronic band allocation through virtual CPE software control, eliminating the need for physical configuration changes and manual intervention in band management operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In a communication system including first virtual CPE and second virtual CPE, the first virtual CPE includes a band acquisition unit configured to acquire a first contract band set for a subscriber under control of the first CPE and acquire a value of decrease in the first contract band when at least one subscriber terminal of the subscriber transitions from being under control of the first CPE to being under control of the second CPE, and a band control unit configured to control a communication band for the first CPE, and the second virtual CPE includes a band acquisition unit configured to acquire a second contract band set for a subscriber under control of the second CPE and acquire a value of increase in the second contract band, and a band control unit configured to control a communication band for the second CPE.
