TSN Network Slicing for Deterministic 5G Service Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G network slicing does not adequately meet timing requirements for different services, necessitating a time-sensitive solution to ensure deterministic communication and synchronization across network slices.
Innovation Solution
Integrate time-sensitive networking (TSN) into 5G network slicing by implementing separate and distinct TSN streams for individual network slices, utilizing centralized SDN-based management and control to configure and manage network resources, ensuring deterministic communication and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 5G network slicing is implemented without TSN integration, then network virtualization and service customization are enabled, but timing requirements and synchronization for different services cannot be met
Solution Approach 1:
The patent segments the network into multiple virtual network slices, each dedicated to specific services with distinct timing requirements. By creating separate logical networks over the shared physical infrastructure, each slice can be independently configured with appropriate TSN policies to meet its specific timing and synchronization needs, thus resolving the contradiction between network versatility and timing reliability.
2Reliability
If separate TSN streams are implemented for each network slice, then deterministic communication and synchronization are achieved, but network complexity and management overhead increase
Solution Approach 1:
The patent introduces a centralized SDN controller as an intermediary that automatically manages TSN stream configuration, mapping, and policy enforcement across network slices. This intermediary abstracts the complex TSN management tasks from individual network elements, enabling deterministic communication through automated stream allocation and synchronization while reducing overall network management complexity.
3Extent of automation
If centralized SDN-based management is used to configure TSN streams, then automated resource allocation and policy enforcement are achieved, but control system complexity increases
Solution Approach 1:
The patent designs the centralized SDN controller to perform multiple functions including TSN stream configuration, network slice management, policy enforcement, and synchronization coordination. By consolidating these diverse functions into a single multi-functional control system, the patent achieves high automation for TSN stream configuration while avoiding the need for multiple specialized control systems, thus balancing automation extent with control system complexity.
