Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If 5G-based positioning technologies are used with LMF in end-to-end network topology, then positioning capability is achieved, but data packet transmission jitter causes delays in data reporting, resulting in decreased accuracy and response speed

Engineering Contradiction:
Improvepositioning accuracyVSAvoiddata reporting delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the positioning data collection and processing functions from the centralized LMF and distributes them to individual base stations. Each base station independently collects performance indicators from user equipment and performs local positioning calculations, eliminating the need for data to traverse the entire end-to-end network topology and reducing transmission delays.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the positioning system into independent base station units, where each base station autonomously performs positioning tasks for user equipment in its coverage area. This segmentation allows parallel processing of positioning data across multiple base stations, improving both response speed and accuracy while reducing network transmission burden.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If multiple base stations are deployed to improve positioning accuracy, then measurement precision increases, but device complexity and deployment cost increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent enables each base station to independently perform positioning calculations using locally collected performance indicators without requiring complex centralized processing or coordination with other base stations. This self-service approach simplifies the overall system architecture while maintaining high positioning accuracy through the use of advanced signal processing algorithms at each base station.

Inventive Principle:
Principle #25Self-service

AI summary

An indoor occupancy distribution analysis system is provided, which includes a base station and a network management device that communicate with each other. The base station is configured to collect performance indicators corresponding to each user equipment from the base station. The performance indicators are associated with the communication between the user equipment and the base station. The network management device is configured to receive these performance indicators, input them into a classifier, obtain the inference result output by the classifier, and derive occupancy distribution from the inference result.
