Solution Overview

Problem

Current DCCF and NWDAF frameworks in telecommunications infrastructure lack a standardized interface for integrating sensing data, which is crucial for applications like IoT, autonomous vehicles, and smart cities, limiting their effectiveness in data collection and analytics.

Innovation Solution

A framework is introduced that includes a Sensing Service Management Function (SSMF) to interface with DCCF and NWDAF, defining sensing data identifiers, event IDs, and metadata to facilitate the collection, processing, and retrieval of sensing data through new interfaces NS5, NS6, and NS7, enabling seamless integration of sensing data into existing models.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the current DCCF and NWDAF framework is used, then network performance data and UE behavior data can be collected and analyzed, but sensing data cannot be integrated due to lack of standardized interface

Engineering Contradiction:

Improvedata integration capabilityVSAvoidsensing data

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent extends the existing DCCF and NWDAF framework to handle multiple data types (network performance data, UE behavior data, and sensing data) through a universal standardized interface. The SSMF acts as a multi-functional component that can collect and manage different categories of data, allowing the system to serve both traditional network analytics and emerging sensing applications through the same infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a new SSMF component that segments the data collection functionality specifically for sensing data, while maintaining the existing DCCF and NWDAF components for network performance and UE behavior data. This segmentation allows sensing data to be handled through a dedicated interface (NS7) while integrating with the overall framework through standardized connections (NS5, NS6).

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If sensing data integration is added to the existing framework, then sensing data can be collected and analyzed, but the framework complexity increases

Engineering Contradiction:

Improvesensing data integrationVSAvoidframework structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The SSMF serves as an intermediary component between the sensing services and the existing DCCF/NWDAF framework. It provides a standardized interface (NS7) for sensing data collection and uses standardized interfaces (NS5, NS6) to communicate with existing components, thereby integrating sensing data functionality without requiring modifications to the core DCCF and NWDAF structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds sensing data integration as a new dimension to the existing framework by introducing a vertical interface layer (NS7) that connects sensing services to the horizontal data flow between DCCF and NWDAF. This dimensional addition allows sensing data to flow through the framework without disrupting the existing data collection and analytics pathways.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

This disclosure describes systems, methods, and devices related to sensing service coordination. A device may discover a Network Data Analytics Function (NWDAF) via a Network Function Repository Function (NRF). The device may send an Analytics request or subscribe to the selected NWDAF with a criteria based on a sensing data analytics ID, event ID, and event parameters. The device may select a Data Collection Coordination Function (DCCF) instance when DCCF is used for data collection, based on DCCF Serving Area Information. The device may receive sensing data or data analytics from the NWDAF after NWDAF has processed the data collected from DCCF.
