5G Virtual Bridge Mapping Across Multiple TSN Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in adapting 5G systems to support and interact with multiple TSC/TSN domains, leading to scalability and flexibility issues due to a one-to-one mapping between 5GS virtual bridges and UPFs, which hinders network management and communication across different TSN domains.
Innovation Solution
A method and network node that dynamically model 5G virtual bridges based on port grouping, allowing interaction with multiple TSN domains by instantiating virtual bridges and user plane functions as needed, decoupling the one-to-one mapping with UPFs, and enabling interaction with non-3GPP network controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 5G network slices are established for different TSN domains, then service customization and QoS differentiation are improved, but network complexity and management overhead increase
Solution Approach 1:
The patent introduces a centralized network slice manager as an intermediary component that coordinates slice establishment, configuration, and management across multiple TSN domains. This mediator abstracts the complexity of multi-domain slice management, allowing customized service configurations without directly increasing operational complexity at network elements.
Solution Approach 2:
The patent develops a universal network slicing framework that can accommodate multiple TSN domains and different service requirements through a common architecture. This multi-functional approach enables the same infrastructure to support diverse services (industrial control, augmented reality, autonomous driving) while maintaining manageable complexity through standardized procedures.
2Adaptability or versatility
If multiple TSN domains are integrated with 5G network, then service coverage and functionality are improved, but synchronization difficulty and management overhead increase
Solution Approach 1:
The patent merges multiple TSN domain management functions into a unified 5G network slicing architecture. By combining domain-specific management with network-wide coordination through the slice manager, the system achieves broad service coverage while reducing management overhead through consolidation and standardization of control functions.
3Reliability
If network slicing is implemented for TSN services, then QoS guarantee and service reliability are improved, but processing overhead and system complexity increase
Solution Approach 1:
The patent implements preliminary configuration of network slice parameters, QoS policies, and resource allocations before actual service deployment. By pre-establishing slice templates and quality-of-service profiles, the system ensures reliable service delivery while reducing real-time processing complexity through advance preparation of configuration data.
