Height-Based Measurement Report Settings for Aerial UE Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile networks are not optimized for aerial UEs, leading to signal drops and inefficient handovers due to varying altitude thresholds and interference, and lack standardization for preventing aerial UEs from entering restricted areas.
Innovation Solution
A height-based management platform adjusts altitude thresholds and customizes measurement report settings for aerial UEs, defining geofences by lowering thresholds for cells near restricted areas and blacklisting unsuitable handover targets, thereby optimizing network performance and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile networks use standard terrestrial height thresholds for all UEs, then network configuration is simple and standardized, but aerial UEs experience signal drops and inefficient handovers due to varying altitude conditions
Solution Approach 1:
The patent applies local quality by implementing height-specific measurement report configurations tailored to aerial UEs. Different measurement report settings are applied based on the UE's height category (terrestrial vs. aerial), allowing the network to optimize connectivity reliability for aerial UEs without affecting terrestrial UEs. This resolves the contradiction by making the network configuration adaptive to local conditions (altitude) rather than uniformly complex for all UEs.
2Productivity
If mobile networks implement customized height-based measurement report settings for aerial UEs, then network performance and connectivity are improved, but device and network complexity increases
Solution Approach 1:
The patent implements parameter changes by introducing height-based thresholds and measurement report configurations that vary according to UE altitude. The network configures different measurement report parameters (such as reporting thresholds, intervals, and criteria) based on whether the UE is terrestrial or aerial. This allows optimized network operation efficiency for aerial UEs while managing complexity through systematic parameter differentiation rather than ad-hoc configurations.
Solution Approach 2:
The patent applies dynamics by making measurement report configurations adaptive to the UE's current height state. The network can dynamically adjust measurement report settings as UEs transition between height categories, enabling efficient network operation for aerial UEs while maintaining flexibility to respond to changing conditions rather than requiring static complex configurations.
3Use of energy by moving object
If mobile networks use uniform handover thresholds, then network management is simplified, but aerial UEs experience unnecessary handovers and increased energy consumption
Solution Approach 1:
The patent applies local quality by implementing height-specific handover thresholds and measurement report configurations that differentiate between terrestrial and aerial UEs. Aerial UEs receive customized handover parameters optimized for their altitude conditions, reducing unnecessary handovers and energy consumption. This resolves the contradiction by making handover management adaptive to local altitude conditions rather than requiring uniformly simplified management for all UEs.
4Reliability
If mobile networks implement geofencing for restricted areas, then aerial UE safety and security are improved, but network configuration and enforcement complexity increases
Solution Approach 1:
The patent implements parameter changes by using height-based thresholds and measurement report configurations as the mechanism for geofencing enforcement. Rather than implementing complex geographic boundary systems, the network uses configurable height parameters to define restricted zones (e.g., preventing handovers above certain altitudes near sensitive areas). This approach improves aerial UE operational safety while managing complexity through parameter-based control rather than complex spatial enforcement mechanisms.

AI summary
Aspects of the subject disclosure may include, for example, receiving information regarding an aerial UE that is communicatively coupled with a network node, obtaining data associated with the network node that correlates altitude values with signal quality levels and/or probabilities of connectivity disruption, determining a conservative height threshold and an aggressive height threshold for the network node based on the data, wherein the conservative threshold is lower than the aggressive threshold, analyzing the information regarding the aerial UE, based on the analyzing, selecting either the conservative threshold or the aggressive threshold for the network node to use for the aerial UE, resulting in a selected height threshold, wherein the selected height threshold affects a frequency or likelihood of height-based trigger events for the aerial UE, and causing the network node to include the selected threshold in height-based measurement report settings for the aerial UE.
