Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G cellular wireless standards lack a deterministic Quality of Service (QoS) model to support real-time, deterministic communication, and there is a need for seamless integration with time-sensitive Ethernet networks to enable the replacement of wired TSN-compliant Ethernet links with wireless 5G links.
Innovation Solution
A QoS framework for 5G networks that includes a Time Sensitive Application Function (TS AF) to interact with the 5G Core Network, define a Time-Sensitive QoS Profile, and establish procedures for end-to-end time-sensitive traffic flows, enabling translation between deterministic and mobile communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional QoS mechanisms are used in mobile networks, then basic service quality is maintained, but deterministic timing requirements and ultra-reliable low-latency communication cannot be satisfied
Solution Approach 1:
The patent introduces a network slice selection function and QoS translation mechanism as an intermediary layer between the deterministic communication network and the mobile network. This intermediary translates QoS parameters from the deterministic network into mobile network QoS parameters, enabling deterministic timing requirements to be satisfied while maintaining compatibility with the existing mobile network architecture.
Solution Approach 2:
The patent segments the mobile network into multiple network slices, each with specific QoS characteristics. By creating dedicated network slices for deterministic communication requirements, the system can provide deterministic timing behavior for specific services while other network slices continue to operate with conventional QoS mechanisms, thus maintaining overall system versatility.
2Adaptability or versatility
If existing QoS parameter sets are used, then compatibility with current networks is maintained, but time-aware QoS requirements for industrial applications cannot be met
Solution Approach 1:
The QoS translation function acts as an intermediary that automatically maps deterministic network QoS parameters to mobile network QoS parameters. This translation mechanism adds time-aware QoS support without requiring complex manual configuration, as the translation is performed automatically by the network function.
Solution Approach 2:
The patent creates a universal QoS framework that can handle both conventional mobile network QoS requirements and deterministic time-aware QoS requirements through a single translation mechanism. This multi-functional approach allows the system to support diverse applications without requiring separate complex parameter sets for each use case.
3Reliability
If deterministic communication requirements are implemented, then ultra-reliable low-latency communication is achieved, but integration with mobile network infrastructure becomes difficult
Solution Approach 1:
The patent implements network slicing to create dedicated virtual networks within the mobile infrastructure that can satisfy deterministic communication requirements. By segmenting the network into slices with specific QoS guarantees, ultra-reliable low-latency communication is achieved for industrial applications while the rest of the mobile network continues to operate independently, reducing integration complexity.
Solution Approach 2:
The QoS translation function and network slice selection function serve as intermediaries that bridge deterministic communication requirements with mobile network infrastructure. These intermediaries handle the complexity of integration by automatically translating parameters and selecting appropriate network slices, thereby achieving reliable low-latency communication without requiring complex manual integration efforts.
