Solution Overview
Problem
Existing communication systems face challenges in efficiently mapping uplink data streams from Time Sensitive Networks (TSN) to protocol data unit sessions or quality of service flows, especially in integrated wired and wireless networks.
Innovation Solution
An apparatus and method for determining mapping rules by receiving forwarding tables from a centralized network configuration entity of a TSN, and using this information to map uplink data streams to protocol data unit sessions or quality of service flows, while also managing uplink classifiers and branching points to optimize network traffic routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mapping rules are determined based on forwarding tables from a centralized network configuration entity, then the mapping accuracy and network traffic routing optimization is improved, but the system complexity and configuration management difficulty increase
Solution Approach 1:
The system segments the mapping rule determination process by separating the centralized network configuration entity that generates forwarding tables from the user equipment that applies mapping rules. This segmentation allows centralized management of mapping accuracy while reducing the complexity burden on individual user equipment devices.
Solution Approach 2:
The patent introduces forwarding tables as an intermediary data structure between the centralized network configuration entity and the user equipment. These forwarding tables serve as a mediator that contains pre-processed mapping information, enabling accurate mapping rules to be derived without requiring user equipment to directly manage complex network configuration details.
2Adaptability or versatility
If uplink classifiers and branching points are inserted or removed based on entry information, then network traffic routing flexibility is improved, but the operational complexity and control difficulty increase
Solution Approach 1:
The system dynamically inserts or removes uplink classifiers and branching points based on entry information from forwarding tables. This dynamic adjustment capability provides routing flexibility to adapt to changing network conditions while the automated decision-making process reduces operational complexity by eliminating manual configuration requirements.
Solution Approach 2:
The user equipment autonomously determines mapping rules and manages uplink classifiers based on received forwarding tables, without requiring manual network configuration or complex operational control. This self-service capability enables routing flexibility while simplifying operations by allowing devices to automatically adapt to network changes.
3Productivity
If mapping rules are determined using entry information from forwarding tables, then data stream mapping efficiency is improved, but the processing time and computational resources increase
Solution Approach 1:
The centralized network configuration entity performs preliminary action by pre-processing and generating forwarding tables that contain essential mapping information before it reaches user equipment. This preliminary preparation reduces the processing time and computational resources required at the user equipment level, as they only need to apply pre-processed rules rather than perform complex real-time analysis.
