Solution Overview

Problem

Existing systems face challenges in determining optimal auxiliary Radio Access Networks (RANs) for terminal devices to assist in sensing tasks, as the currently camped RAN may not be suitable for specific sensing requirements.

Innovation Solution

A communication method is implemented to query attribute information of multiple RANs, enabling the determination of auxiliary RANs for terminal devices by sending request information to query and associate measurement and attribute information, facilitating effective sensing task assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device uses the currently camped RAN as an auxiliary RAN for sensing, then the system can achieve simple operation and quick deployment, but the sensing accuracy and effectiveness may be insufficient when the camped RAN is not suitable for specific sensing tasks

Engineering Contradiction:
Improvesensing effectivenessVSAvoidauxiliary RAN selection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The terminal device autonomously performs sensing measurements on multiple RANs and autonomously determines which RANs are suitable as auxiliary RANs based on measurement results and attribute information, without requiring complex network-side coordination for selection

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The terminal device reports measurement information and attribute information of detected RANs to the network device, enabling the network to make informed decisions about auxiliary RAN selection based on actual sensing capabilities and conditions

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system queries and associates measurement information and attribute information of multiple RANs to determine optimal auxiliary RANs, then the sensing accuracy is improved, but the information processing complexity and time consumption increase

Engineering Contradiction:
Improvesensing measurement accuracyVSAvoidauxiliary RAN determination time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

RANs pre-store and manage their own attribute information (such as sensing capabilities, frequency support, etc.), so that when the terminal device needs to determine auxiliary RANs, the information is already prepared and readily available, reducing query and processing time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system divides the auxiliary RAN determination process into independent components: terminal device performs measurements, collects attribute information, and reports to the network device, which then makes the final determination. This segmentation allows parallel processing and reduces overall time consumption

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the terminal device requires multiple auxiliary RANs besides the currently camped RAN for sensing tasks, then the sensing capability and coverage are enhanced, but the device complexity and resource management difficulty increase

Engineering Contradiction:
Improvesensing task adaptabilityVSAvoidmultiple RAN management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The network device serves as a universal coordinator that manages multiple auxiliary RANs for different terminal devices and different sensing tasks, providing a standardized interface and management mechanism that simplifies the complexity of managing multiple RAN connections

Inventive Principle:
Principle #6Universality (Multi-functionality)
