Solution Overview

Problem

Existing wireless communication systems fail to support time-sensitive data transmission due to shared network resources and delays, particularly in time-sensitive networks where bridge-related information control and management are not adequately addressed.

Innovation Solution

Implementing a method and device for information transmission that includes obtaining and sending bridge-related information between ports of time-sensitive network translators (TSN translators), determining port pairs, and managing bridge delays through port-associated tunnels or preconfigured communications, ensuring efficient data transmission in time-sensitive networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network transmission resources are shared, then network resource utilization is improved, but transmission delays and jitters occur that cannot support time-sensitive data

Engineering Contradiction:

Improvenetwork resource utilizationVSAvoidtransmission delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments network resources by introducing dedicated time-sensitive network resources separate from shared resources. Time-sensitive data is transmitted through dedicated channels while other data uses shared resources, eliminating the conflict between resource utilization and transmission delay requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a time-sensitive network translator (TSN translator) as an intermediary device that bridges traditional shared network resources and time-sensitive communication requirements. The translator manages packet prioritization, timing synchronization, and resource allocation to ensure deterministic transmission while maintaining overall network resource efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If bridge-related information is not properly managed, then network complexity is reduced, but time-sensitive data transmission cannot be supported

Engineering Contradiction:

Improvenetwork management complexityVSAvoidtime-sensitive data transmission reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements preliminary configuration of bridge-related information including port pair associations, delay budgets, and priority levels before time-sensitive data transmission begins. This pre-configuration enables deterministic handling of time-sensitive packets without requiring complex real-time management decisions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent establishes feedback mechanisms where the TSN translator monitors transmission delays, packet timing, and resource utilization, then adjusts bridge management parameters dynamically. This closed-loop control ensures time-sensitive transmission reliability while maintaining manageable network complexity through automated adaptation.

Inventive Principle:

Principle #23Feedback
