Solution Overview

Problem

The integration of 5G Systems (5GS) and Deterministic Networking (DetNet) networks is hindered by disjoint configuration domains, leading to compatibility issues and the lack of seamless interworking, which is crucial for real-time applications with stringent data loss, jitter, and latency requirements.

Innovation Solution

A method for configuration mapping is introduced, where a DetNet controller translates configuration parameters using a YANG model to 3GPP models, enabling efficient interworking by mapping parameters like maximum latency, loss, and bandwidth requirements between DetNet and 3GPP domains through network nodes such as TSCTSF, PCF, and SMF.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If configuration parameters are transmitted between DetNet controller and 3GPP network nodes, then interworking between domains is enabled, but complexity of configuration mapping increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces intermediary configuration mapping functions at network nodes (TSCTSF, PCF, SMF) that translate between DetNet YANG model parameters and 3GPP configuration parameters. These intermediaries handle the complexity of parameter mapping, allowing seamless interworking between DetNet and 3GPP domains without requiring the controller to manage all mapping details directly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If configuration parameters are mapped between DetNet YANG model and 3GPP model, then compatibility between domains is achieved, but information loss may occur during translation

Engineering Contradiction:

Improvedomain compatibilityVSAvoidconfiguration information loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements feedback mechanisms where network nodes transmit success or failure information back to the DetNet controller regarding configuration parameter application. This feedback loop allows the controller to verify whether configuration parameters were successfully mapped and applied, enabling corrective actions if information loss or mapping failures occur during translation between domains.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If configuration parameters are transmitted and mapped across network nodes, then seamless interworking is enabled, but transmission time and delays increase

Engineering Contradiction:

Improveseamless interworkingVSAvoidconfiguration transmission time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs preliminary configuration mapping where network nodes pre-process and map configuration parameters before actual data transmission begins. By preparing the configuration mapping in advance, the system reduces real-time transmission delays and enables faster establishment of deterministic data paths while maintaining seamless interworking between domains.

AI summary

A method for configuration mapping in a communications network. The method includes transmitting from a controller entity to a first network node at least one first configuration parameter; mapping at the first network node the at least one first configuration parameter to at least one second configuration parameter; transmitting from the first network node to a second network node the at least one second configuration parameter; and initiating at the second network node modification actions in the communications network.
