TSN Translator for 3GPP Network Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack seamless integration of 3GPP wireless networks with Time Sensitive Networking (TSN) networks, which is essential for providing deterministic communication in industrial environments, as they are managed independently without overarching entities to handle interactions between these domains.
Innovation Solution
The integration is achieved through a TSN Translator and TSN Translator Client that map TSN protocols to 3GPP commands, enabling transparent integration by treating the 3GPP network as a TSN bridge, with a Management & Orchestration entity intercepting messages between TSN CNC and CUC to optimize resource allocation and QoS management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3GPP wireless networks and TSN networks are managed independently without integration, then each network can maintain its own management simplicity, but seamless integration and deterministic communication in industrial environments cannot be achieved
Solution Approach 1:
The patent introduces a TSN Translator as an intermediary device that bridges the 3GPP wireless network and TSN network domains. The translator maps 3GPP QoS parameters to TSN delay parameters and protocols, enabling seamless integration without requiring modifications to existing networks. This intermediary handles the complexity of inter-domain communication while presenting simple interfaces to both networks.
2Adaptability or versatility
If wireless transmission mechanisms are used to connect sensors and actuators to TSN network, then mobility and scalability are improved, but deterministic delay requirements become harder to guarantee
Solution Approach 1:
The patent transforms the wireless network's QoS parameters (through the TSN Translator) into TSN-compatible delay parameters. By mapping 3GPP QoS parameters to deterministic TSN delay budgets and scheduling parameters, the system guarantees deterministic delay performance over wireless links while maintaining mobility and scalability benefits.
3Reliability
If TSN protocols are directly applied to 3GPP wireless networks, then deterministic communication can be achieved, but existing networks require modifications
Solution Approach 1:
The TSN Translator serves as a protocol translation intermediary that converts TSN protocols into 3GPP-compatible commands and parameters. This allows deterministic TSN communication to be achieved over 3GPP wireless networks without modifying the core 3GPP network infrastructure, as the translator handles all protocol adaptations.
Solution Approach 2:
The patent creates a virtual representation of TSN network behavior within the 3GPP domain through the translator. It copies TSN protocol functions and mappings into the 3GPP network environment, allowing deterministic communication without direct implementation of TSN protocols in the wireless network core.
