Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G mobile communication systems face challenges in effectively integrating time-sensitive networking (TSN) and deterministic networking (DetNet) technologies to provide latency-guaranteed services, as they struggle with converting end-to-end routing information between different network architectures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G mobile communication systems integrate TSN and DetNet technologies to provide latency-guaranteed services, then service reliability is improved, but device complexity increases due to the need for routing information conversion between different network architectures
Solution Approach 1:
The patent introduces a TSCTSF (Time-Sensitive Communication and Time Synchronization Function) entity as an intermediary component that performs routing information conversion between DetNet and 5GS networks. This mediator handles the complexity of converting end-to-end routing information from DetNet format into 5G-compatible routing information, thereby enabling reliable latency-guaranteed services without exposing the overall system complexity to end users or requiring manual configuration of conversion rules.
2Adaptability or versatility
If the system converts end-to-end routing information from DetNet to 5G format, then network adaptability is improved, but processing time increases due to the conversion operation
Solution Approach 1:
The patent implements preliminary action by pre-configuring the TSCTSF entity with conversion parameters and routing rules before actual data transmission occurs. The entity maintains predefined mapping relationships between DetNet routing information and 5G routing information, enabling rapid conversion during operation without requiring real-time analysis or complex processing, thus minimizing time loss while maintaining high network adaptability.
3Adaptability or versatility
If the TSCTSF entity receives and converts routing information from multiple network functions, then system integration is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the TSCTSF entity as a multi-functional component that performs multiple tasks: receiving routing information from various network functions (SMF, UPF), converting routing information between different network formats, and forwarding processed information to appropriate destinations. This universal entity handles diverse routing conversion requirements through a unified architecture, improving system integration capability while managing complexity through functional consolidation rather than proliferation of specialized components.

AI summary
The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. A method performed by a time sensitive communications and time synchronization function (TSCTSF) entity in a wireless communication system may comprise receiving internet protocol (IP) information on a user equipment (UE) from a session management function (SMF) entity, receiving IP information on a user plane function (UPF) entity from the UPF entity, receiving, from a deterministic networking (DetNet) controller, end-to-end (E2E) routing-related information for routing of a fifth generation system (5GS) including the TSCTSF entity, and identifying information on a parameter for the routing of the 5GS on the basis of the E2E routing-related information, wherein the routing of the 5GS may be based on the IP information on the UE and the IP information on the UPF entity.
