eNB Geographic Bin Data Collection and Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in efficiently collecting, filtering, and transmitting large amounts of geographic bin data, which can cause congestion and hinder the processing of useful data, especially in busy areas.
Innovation Solution
An Evolved Node-B (eNB) is configured to measure the angle of arrival and propagation delay of mobile devices to select geographic bins and send performance data to a Trace Collection Entity (TCE) only when a threshold number of devices are within a bin, using a Minimization of Drive Testing (MDT) control message that includes a geographic bin information element (IE) to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If geographic bin data is collected from all mobile devices in busy areas, then data completeness is improved, but network congestion increases and processing efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating data collection strategies based on geographic location characteristics. Geographic bins are classified into different types (e.g., high-traffic vs. low-traffic areas), and data collection is intensified only in bins where it provides value. This selective approach maintains data completeness in critical areas while reducing overall data volume to improve processing efficiency.
Solution Approach 2:
The patent segments the geographic coverage area into discrete bins, allowing independent data collection decisions for each bin. This segmentation enables the system to apply different collection thresholds and strategies to different bins, collecting detailed data only where necessary while aggregating or skipping data in less critical bins, thus resolving the contradiction between completeness and processing efficiency.
2Loss of information
If geographic bin data is transmitted over backhaul from base station, then data availability for processing is improved, but network congestion increases
Solution Approach 1:
The patent extracts only the essential and useful geographic bin data for transmission over the backhaul, leaving non-critical data at the base station or filtering it out entirely. By taking out only the necessary subset of data (those bins meeting collection criteria, aggregated statistics, or anomaly-detected bins), the system maintains data availability for processing while minimizing the harmful effect of network congestion.
Solution Approach 2:
The patent applies partial action by transmitting a subset of geographic bin data rather than all collected data. The system uses thresholds and filtering criteria to determine which bins warrant transmission, sending only partial data that is sufficient for network optimization purposes while avoiding the excessive data transmission that would cause congestion.
3Object-generated harmful factors
If data filtering is applied to reduce transmission volume, then network congestion is reduced, but data processing complexity at base station increases
Solution Approach 1:
The patent applies preliminary action by performing data filtering, aggregation, and preliminary analysis at the base station before transmission. The base station pre-processes the geographic bin data, applying filters and selection criteria in advance, so that only pre-processed and filtered data needs to be transmitted. This shifts processing complexity to the base station but reduces network congestion and simplifies downstream processing.

AI summary
Embodiments of an Evolved Node-B (eNB) and method for collecting and reporting data related to a coverage area in a wireless network are generally described herein. The eNB may be configured to track geographic bin information for one or more User Equipment (UEs). The eNB may comprise hardware processing circuitry configured to, for each of the UEs, measure an angle of arrival for the UE and a propagation delay for the UE, and to select a geographic bin for the UE from a set of candidate geographic bins. The hardware processing circuitry may be further configured to send, for each of the candidate geographic bins, performance data for the candidate geographic bin to the TCE when a number of UEs for which the candidate geographic bin is selected is not less than a UE distribution threshold.
