Solution Overview

Problem

Existing AI/ML models for terminal device positioning suffer from low accuracy due to unreliable label information, especially in scenarios with large Non-Line of Sight diameters, leading to positioning errors greater than 10 meters.

Innovation Solution

A method for acquiring label information involves a first network device determining a correction parameter to refine the label information of a data set, using actual information from terminal devices to correct initial label information, thereby improving the reliability of the data set for training an AI/ML model.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional positioning methods are used, then the system is simple to implement, but the positioning accuracy deteriorates with large Non-Line of Sight diameters

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-collecting actual positioning information from terminal devices and pre-calculating correction parameters before the AI/ML model training process. The network device obtains actual position information through traditional positioning methods or GPS, then calculates correction parameters in advance to improve the reliability of label information for model training, thereby enhancing positioning accuracy without increasing real-time system complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary element - the correction parameter - that mediates between traditional positioning methods and AI/ML model training. The correction parameter acts as a bridge to refine label information by comparing initial label information with actual positioning information, thereby improving positioning accuracy without requiring fundamental changes to the system architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements feedback by using actual positioning information to calculate correction parameters that refine label information. The network device obtains actual position information, compares it with initial label information, and uses the difference as feedback to generate correction parameters. This feedback mechanism improves the reliability of label information for AI/ML model training, thereby enhancing positioning accuracy

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies parameter changes by modifying label information through correction parameters. The correction parameters adjust the initial label information based on the difference between initial and actual positioning information. This parameter transformation improves the accuracy of label information without requiring complex reprocessing of the entire dataset

Inventive Principle:
Principle #35Parameter changes
