Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Minimization of Drive Tests (MDT) technology in wireless communication systems is limited in data collection, allowing only parameters related to signal coverage, which reduces the accuracy of network optimization due to the limited data collection ability of common terminals.
Innovation Solution
A method and system where a base station receives drive test instructions with multiple types of data information, acquiring corresponding data itself and instructing terminals to collect additional data types, thereby increasing the variety of drive test data collected and improving network optimization accuracy.

Engineering Contradiction Analysis
1Loss of energy
If common terminals are configured to participate in drive test work, then resource cost on drive test is decreased, but data collection ability is limited to only signal coverage parameters
Solution Approach 1:
The patent segments the drive test data collection function into two parts: common terminals collect basic signal coverage parameters, while base stations collect additional parameters (throughput, delay, packet loss rate) that require more sophisticated measurement capabilities. This segmentation allows resource-efficient terminal participation while maintaining comprehensive data collection through base station supplementation.
Solution Approach 2:
The base station acts as an intermediary that receives drive test instructions from the OAM system, determines which parameters to collect, and coordinates with terminals to gather both terminal-collected and base-station-collected parameters. The base station consolidates these data sources to provide comprehensive drive test results to the OAM system.
2Device complexity
If only signal coverage parameters are collected by common terminals, then device complexity is reduced, but measurement precision for network optimization is reduced
Solution Approach 1:
The patent merges data collection from two sources: common terminals providing signal coverage parameters and base stations providing additional parameters (throughput, delay, packet loss rate). The base station combines these diverse data sources to create a comprehensive drive test dataset that achieves high measurement precision for network optimization without requiring enhanced terminal capabilities.
