Wireless Bridge TSN Capability Estimation for Variable Throughput

Solution Overview

Problem

The integration of wireless bridges, such as 5G systems, into Time Sensitive Networking (TSN) networks faces challenges due to variable throughput capacity and unpredictable radio resource allocation, leading to inefficiencies in determining TSN capabilities and causing additional delays and jitter in data streams.

Innovation Solution

A method for calculating the TSN capabilities of wireless bridges by estimating performance capacity based on intended network usage, using quality-of-service templates and adjusting radio resource allocation to match anticipated traffic loads, allowing for more accurate and reliable TSN capability calculations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless bridges are integrated into TSN networks to provide mobility and scalability, then network adaptability is improved, but throughput capacity becomes variable and unpredictable

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by estimating the performance capacity of wireless connections before actual data transmission based on intended network usage. The wireless bridge calculates TSN capabilities in advance using quality-of-service templates that predict radio resource allocation, allowing the system to prepare appropriate resource reservations and scheduling configurations before time-sensitive traffic arrives, thereby ensuring reliable throughput despite the variable nature of wireless media.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If radio resource allocation is adjusted dynamically to match traffic load, then network productivity is improved, but calculation complexity of TSN capabilities increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by introducing quality-of-service templates that define performance capacity parameters based on intended network usage. Instead of performing complex real-time calculations of TSN capabilities under varying traffic loads, the system pre-defines parameter sets (latency, jitter, throughput) corresponding to different usage scenarios. The wireless bridge selects and applies the appropriate parameter set based on current traffic conditions, simplifying the calculation process while maintaining high network efficiency.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If TSN capabilities are calculated without considering intended network usage, then ease of operation is improved, but measurement precision of performance capacity deteriorates

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies self-service by enabling the wireless bridge to autonomously estimate its performance capacity based on intended network usage information. The system automatically generates quality-of-service templates and calculates TSN capabilities without requiring manual configuration or external intervention. This self-service approach maintains ease of operation while achieving precise performance capacity estimation by leveraging the bridge's own knowledge of its wireless connections and intended usage patterns.

Inventive Principle:
Principle #25Self-service
