Distributed TSN Scheduler for 5G Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated Time-Sensitive Network (TSN) and 5G wireless communication systems face limitations in flexibility and redundancy, particularly in industrial automation and manufacturing, where deterministic communication with stringent quality of service parameters is required, as existing configurations do not allow for decentralized setup of 5G components or flexible data transmission paths.
Innovation Solution
The system is configured as a set of discrete 5G components, each acting as a TSN block, with distributed configuration modules that interconnect in various topologies, enabling individual scheduling of TSN flows and supporting time-sensitive interconnection communication across domains through waypoints that connect schedules between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized TSN configuration is used, then scheduling control is simplified, but system flexibility and adaptability are reduced
Solution Approach 1:
The patent segments the centralized TSN configuration into distributed configuration modules deployed across multiple network components. Each module can independently configure and schedule TSN flows within its local domain, enabling decentralized control while maintaining overall system coordination. This segmentation resolves the contradiction by providing both operational simplicity at the local level and system-wide flexibility through modular architecture.
Solution Approach 2:
The patent introduces a multi-dimensional architecture where configuration modules operate at different hierarchical levels - local domain level for immediate scheduling decisions and cross-domain level for end-to-end flow management. This dimensional expansion allows the system to maintain simplified control within each dimension while achieving high adaptability across multiple dimensions simultaneously.
2Device complexity
If fixed data transmission paths are used, then network configuration is simplified, but redundancy and flexibility are reduced
Solution Approach 1:
The patent implements dynamic path selection capabilities where the TSN scheduler can adaptively choose between multiple transmission paths based on real-time network conditions, flow requirements, and quality of service parameters. This dynamic approach maintains simple base configuration while enabling complex redundant path management when needed, resolving the contradiction between configuration simplicity and system reliability.
3Measurement precision
If individual TSN flow scheduling is implemented across multiple domains, then communication precision is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary scheduling actions where configuration modules pre-calculate and establish TSN flow schedules before actual data transmission. By performing scheduling decisions in advance based on predicted traffic patterns and requirements, the system achieves precise timing control without requiring complex real-time calculations, thus resolving the contradiction between timing precision and system complexity.
