Cellular Network Performance Assessment by Filtering Indoor UE Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular network performance data collected by UEs in indoor environments is not a reliable indicator of true network quality, leading to incorrect decisions on cell site deployment and resource allocation, which can result in sub-optimal network performance and overloading of computing systems.
Innovation Solution
A system and method that uses UEs to collect performance indicators, discards data collected during indoor operations, and generates graphs based on outdoor data to accurately assess network quality, ensuring decisions are made on accurate performance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If network performance data is collected from all UEs including those in indoor environments, then the quantity of performance data is increased, but the reliability of network quality assessment deteriorates
Solution Approach 1:
The patent extracts and removes indoor-collected performance data from the overall dataset. The performance server identifies data collected by UEs in indoor environments using indoor/outdoor indicators and excludes this data from network quality assessment, retaining only outdoor-collected data to ensure reliability of the assessment.
2Productivity
If network performance data from indoor environments is used for decision-making, then the productivity of deployment decisions is improved, but the precision of network quality measurement deteriorates
Solution Approach 1:
The patent extracts indoor-collected data from the performance dataset using indoor/outdoor indicators, separating it from outdoor data. This ensures that only precise outdoor measurements are used for deployment decisions, maintaining measurement precision while enabling timely decision-making based on reliable data.
3Ease of operation
If cell site deployment decisions are made based on inaccurate indoor performance data, then the ease of operation in making decisions is improved, but the loss of information about true network quality increases
Solution Approach 1:
The patent removes indoor-collected performance data from the decision-making dataset, ensuring that only accurate outdoor data informs deployment decisions. This prevents loss of true network quality information while maintaining ease of operation through automated data filtering and analysis.
Data Source
AI summary
A database stores data relating to a plurality of performance indicators associated with performance of a cellular network as experienced by a first UE. The data includes data relating to a first set of the performance indicators that indicate a quality of cellular coverage associated with the cellular network as experienced by the first UE and data relating to a second set of the performance indicators that indicate whether the first UE was operating in an indoor environment. It is determined based on the second set of performance indicators whether the UE was operating in an indoor environment for a particular time period. If yes, a portion of the data relating to the first set of performance indicators collected during the particular time period is discarded and the remaining data is plotted on a graph to represent a quality of the cellular network.
