Solution Overview

Problem

In 5G communication systems, existing methods fail to accurately manage and predict tree maps that change over time due to seasonal variations and tree growth, affecting signal propagation and network performance.

Innovation Solution

A server-based method and apparatus that analyze image data to determine whether to regenerate a tree map by comparing current and past tree region data, using techniques such as intersection over union (IOU) and color data differences, and generate a new tree map to account for changes in tree density and size, enabling more accurate propagation simulations.

VSEngineering Contradiction Analysis

1Measurement precision

If tree maps are continuously regenerated using image analysis, then the accuracy of signal propagation simulation is improved, but the computational complexity and processing time increase

Engineering Contradiction:

Improveaccuracy of signal propagation simulationVSAvoidcomputational complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system automatically determines whether tree map regeneration is needed by comparing current images with stored historical images and calculating IOU values, eliminating the need for manual intervention in deciding when to regenerate maps

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system changes the parameter of tree map update frequency from continuous to conditional based on IOU threshold comparison, reducing unnecessary regeneration operations while maintaining simulation accuracy when changes occur

Inventive Principle:

Principle #35Parameter changes

2Reliability

If tree maps are regenerated frequently to capture seasonal changes, then the reliability of propagation environment data is improved, but the loss of time and processing resources increases

Engineering Contradiction:

Improvereliability of propagation environment dataVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs periodic comparison operations between current and historical tree images at predetermined intervals, regenerating tree maps only when actual changes are detected through IOU threshold comparison, rather than continuously or manually

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses feedback from IOU value comparison to determine whether regeneration is necessary, creating a closed-loop control mechanism that adjusts regeneration frequency based on actual environmental changes

Inventive Principle:

Principle #23Feedback

AI summary

A pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE) is provided. The method for operating a server includes receiving a first image including at least one tree, determining whether to generate a tree map based on the first image, based on a difference between first tree region data of the first image and second tree region data of a second image which is prestored, and generating the tree map according to determining.
