5G TSC QoS Flow Configuration for Deterministic Low-Latency Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integration models for 5G systems with Time Sensitive Networks (TSN) face challenges such as multi-vendor integration issues, protocol conversion needs, mismatched support for QoS, dynamic vs. static configuration mismatches, and complex synchronization requirements, making it difficult to provide low-latency, deterministic data transmission.
Innovation Solution
A standalone 5G Time Sensitive Communication (TSC) network is implemented, using a TSC configurator to configure 5G nodes with quality of service parameters for scheduled gate times, eliminating the need for an external TSN network and ensuring deterministic, low-delay communication paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G systems are integrated with external TSN networks using existing integration models, then Time Sensitive Network functionality can be achieved, but multi-vendor integration issues, protocol conversion needs, and complex synchronization requirements increase system complexity and reduce reliability
Solution Approach 1:
The patent extracts the TSN functionality from external networks and integrates it directly into the 5G system core. The TSC configurator is embedded within the 5G core network, allowing 5G nodes to natively support TSC requirements without relying on external TSN network infrastructure, thereby eliminating multi-vendor integration issues and protocol conversion needs
Solution Approach 2:
The patent merges TSN configuration capabilities with the 5G core network by introducing a TSC configurator that works in conjunction with existing 5G network functions. This combination allows the 5G system to simultaneously provide mobile connectivity and deterministic time-sensitive communication services through a unified network architecture
2Adaptability or versatility
If quality of service parameters are dynamically configured for 5G nodes, then adaptability to different communication requirements is improved, but synchronization complexity and configuration overhead increase
Solution Approach 1:
The TSC configurator performs preliminary configuration of quality of service parameters and scheduled gate times before time-sensitive communication begins. By pre-configuring QoS parameters based on anticipated communication requirements, the system achieves adaptability without requiring complex real-time synchronization during actual data transmission
Solution Approach 2:
The TSC configurator acts as an intermediary between network administrators and 5G nodes, translating high-level TSC requirements into specific QoS parameter configurations. This intermediary function simplifies the configuration process by automating the translation of communication requirements into technical parameters, reducing synchronization complexity
3Loss of time
If scheduled gate times are configured at 5G nodes for deterministic transmission, then low-latency communication is achieved, but network configuration complexity increases
Solution Approach 1:
The TSC configurator enables 5G nodes to self-configure their scheduled gate times and QoS parameters automatically. The configurator provides a standardized interface that allows nodes to autonomously determine their transmission schedules based on network conditions and service requirements, reducing the need for manual configuration and lowering overall network configuration complexity
