Solution Overview

Problem

In inverse multiplexing, determining the assignment of partial signals to transmission paths is challenging, especially in optical transport networks, as existing methods require significant effort and do not provide knowledge of signal allocation, affecting transmission quality and performance.

Innovation Solution

The method involves interrupting transmission paths to identify partial signals by examining the reassembled received signal, utilizing frame structures and rolling systems to determine which partial signals are present or missing, allowing for efficient assignment without additional communication overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If training data pattern is transmitted over all sections during configuration process, then automatic configuration of transmission link is achieved, but no user data can be transmitted during this phase

Engineering Contradiction:
Improveautomatic configurationVSAvoiddata transmission capability
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The transmission link is divided into multiple sections, and the training process is segmented to occur only on selected sections rather than all sections simultaneously. This allows other sections to continue transmitting user data without interruption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of applying the training data pattern to all transmission sections (excessive action), the method applies it only to selected sections where configuration is needed (partial action), thereby maintaining data transmission capability on other sections.

Inventive Principle:
Principle #16Partial or excessive action

2Reliability

If signal transmission is interrupted to determine partial signal assignment, then transmission path performance is improved, but transmission continuity is affected

Engineering Contradiction:
Improvetransmission path performanceVSAvoidtransmission continuity
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The transmission link is segmented into multiple sections, and the interruption for assignment determination is applied only to selected sections rather than the entire link. This minimizes the impact on overall transmission continuity while still enabling performance optimization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The method interrupts signal transmission only partially (in selected sections) rather than completely across the entire transmission link, thereby maintaining transmission continuity on unaffected sections while still achieving assignment determination.

Inventive Principle:
Principle #16Partial or excessive action

3Device complexity

If partial signals are assembled without knowledge of signal allocation, then device complexity is reduced, but transmission quality optimization is limited

Engineering Contradiction:
Improvesignal processing complexityVSAvoidtransmission quality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs self-diagnosis by automatically determining the assignment of partial signals to transmission sections through monitoring and analysis, without requiring external configuration or complex pre-programming. This maintains low device complexity while enabling quality optimization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The method implements a feedback mechanism where the receiver monitors the transmitted signals, determines their assignment to transmission sections, and uses this information to optimize transmission quality. This feedback loop enables quality improvement without increasing fundamental system complexity.

Inventive Principle:
Principle #23Feedback

AI summary

The method involves interrupting a signal transmission over transmission links (5a-5d) for a detection process after synchronizing partial signals (S1-S4) to a digital reception signal (E) at a receiver side. Features in the reception signal are detected during the detection process, where the features contain the partial signals incorporated in the reception signal or partial signals not incorporated in the reception signal. The interruption step and the detection step are executed until information is provided for determining the partial signals transmitted over the respective link. An independent claim is also included for a receiver comprising reception units.
