Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G systems face issues with transmission conflicts and poor port configuration during data transmission in time-sensitive networks (TSN), leading to inefficient and unreliable communication.
Innovation Solution
A method for implementing data transmission in TSN systems that involves reporting port management parameters to a centralized network controller (CNC) and using a session management function (SMF) device to manage port resources, ensuring timely and comprehensive port configuration for aperiodic and periodic services, thereby resolving transmission conflicts and optimizing port allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If port management parameters are not reported to CNC, then system complexity is reduced, but transmission reliability deteriorates due to transmission conflicts and poor port configuration
Solution Approach 1:
The patent introduces an intermediary mechanism where the SMF device acts as a mediator between the 5G system and TSN network. The SMF reports port management parameters to the CNC, enabling the CNC to make informed scheduling decisions. This intermediary approach resolves transmission conflicts by providing the CNC with necessary port configuration information without requiring direct complex interactions between all network elements.
Solution Approach 2:
The patent implements preliminary action by having the SMF device report port management parameters to the CNC in advance before data transmission occurs. This allows the CNC to pre-configure port resources and prepare scheduling decisions, preventing transmission conflicts before they happen. The port configuration information is made available beforehand, enabling proactive rather than reactive conflict resolution.
2Productivity
If port resources are not allocated for different service types, then device complexity is reduced, but productivity deteriorates due to transmission conflicts between aperiodic and periodic services
Solution Approach 1:
The patent applies segmentation by dividing port resources into different allocations for aperiodic services and periodic services. The SMF device reports separate port management parameters for different service types, and the CNC allocates specific port pairs for each service category. This segmentation prevents transmission conflicts between services with different timing requirements, improving overall data transmission efficiency.
Solution Approach 2:
The patent implements local quality by providing differentiated port configuration for different service types. Aperiodic services receive port allocations optimized for their specific timing characteristics, while periodic services receive port allocations optimized for their periodic nature. This localized optimization ensures each service type receives appropriate resource allocation without requiring complex global reconfiguration.
3Measurement precision
If port configuration is not optimized for different service types, then ease of operation is improved, but measurement precision deteriorates due to poor time synchronization
Solution Approach 1:
The patent enables self-service by allowing the SMF device to automatically report port management parameters to the CNC based on the service requirements. The system self-configures port allocations for different service types without requiring manual intervention. This automated approach maintains time synchronization accuracy while keeping the operation simple for network operators.
