TSN Bridge Virtual Topology for UE-to-UE 5G Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5GS TSN models fail to effectively depict UE-to-UE communication through base stations, leading to high jitter and poor performance due to structural issues when attempting to add connections for such communication, and do not optimize wireless performance and capacity, especially when packets are transmitted in TDMA fashion.
Innovation Solution
A method for determining a virtual topology of a wireless bridge in a time-sensitive network, comprising a user plane function (UPF) ring bridge connected to separate sides for uplink and downlink communication, utilizing multiplexers and demultiplexers to optimize performance and capacity, allowing UE-to-UE communication through base stations while minimizing transmission jitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connections are added between specific ports to enable UE-to-UE communication, then communication capability is improved, but transmission jitter increases and performance deteriorates
Solution Approach 1:
The bridge model is segmented into separate functional components: a first side for uplink communication, a second side for downlink communication, and a UPF ring bridge connecting them. This segmentation allows independent optimization of each communication direction and enables UE-to-UE communication without creating direct connections that cause jitter, instead routing traffic through the segmented UPF ring structure.
Solution Approach 2:
The UPF ring bridge acts as an intermediary component between the first side (uplink) and second side (downlink). It mediates the communication between UEs by routing packets through the user plane function, enabling UE-to-UE communication while maintaining controlled transmission paths that reduce jitter and improve reliability.
2Adaptability or versatility
If a traditional bridge model is modified to support UE-to-UE communication, then communication functionality is improved, but wireless performance and capacity optimization is compromised
Solution Approach 1:
The bridge model segments communication into separate uplink and downlink paths with dedicated handling. The first side handles uplink traffic from UEs to the network, while the second side handles downlink traffic from the network to UEs. This segmentation enables independent optimization of each direction and allows the system to achieve both UE-to-UE communication functionality and optimized wireless performance through proper resource allocation and scheduling on each side.
Solution Approach 2:
The UPF ring bridge serves multiple functions: it enables UE-to-UE communication, optimizes wireless performance, manages capacity, and handles both uplink and downlink traffic. This multi-functional design allows a single component to address multiple requirements simultaneously, improving both communication functionality and wireless performance without compromising either aspect.
3Productivity
If multiplexing capabilities are utilized for TDMA packet transmission, then capacity is improved, but transmission complexity increases
Solution Approach 1:
The multiplexer and demultiplexer components automatically manage packet routing and resource allocation based on the virtual topology configuration. The system self-adjusts to optimize capacity utilization for TDMA transmission without requiring complex manual configuration or control, thereby improving wireless capacity while keeping the operational complexity manageable through automated mechanisms.
