Cellular Aerial Vehicle Identification for Unauthorized Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial vehicles in cellular networks can cause interference and are often unauthorized, posing a challenge for network management and security.
Innovation Solution
A system and method for aerial vehicle identification that includes transmitting a request for information to remote units to determine unauthorized aerial vehicles, using location and certification data to assess authorization, and handling unauthorized units by limiting access or behavior within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aerial vehicles are allowed to access the cellular network freely, then network coverage and service availability are improved, but network interference increases and security deteriorates
Solution Approach 1:
The system performs preliminary identification of aerial vehicles by analyzing uplink signals before granting network access. Base units detect and identify aerial remote units through signal characteristics, and the network proactively establishes rules to restrict unauthorized aerial vehicles before they can cause interference, rather than reacting after interference occurs
Solution Approach 2:
The patent introduces an intermediary identification mechanism between aerial vehicles and the cellular network. Base units act as intermediaries that detect aerial remote units, analyze their signals, and determine whether they are authorized before allowing network access. This intermediary layer filters out unauthorized aerial vehicles that would otherwise cause interference
2Adaptability or versatility
If all remote units are granted network access, then service coverage is improved, but unauthorized aerial vehicle identification becomes more difficult
Solution Approach 1:
The system applies different quality levels of access control to different remote units. Authorized aerial vehicles receive full network access with appropriate services, while unauthorized aerial vehicles are identified and restricted. The base units analyze local signal characteristics of each remote unit to determine authorization status, applying differentiated access policies rather than uniform treatment
Solution Approach 2:
The system implements feedback mechanisms where base units continuously monitor uplink signals from remote units, identify aerial vehicles based on signal characteristics, and provide feedback by granting or restricting access. The network receives information about aerial vehicle presence and responds by applying appropriate access control policies, creating a closed-loop identification and management system
3Reliability
If network access is restricted for aerial vehicles, then interference is reduced and security is improved, but network coverage and service availability deteriorate
Solution Approach 1:
The system establishes access control rules preliminarily for authorized aerial vehicles before they attempt to access the network. By pre-identifying and authorizing legitimate aerial remote units, the system ensures they can access network services without restriction, while simultaneously preparing restrictions for unauthorized vehicles. This preliminary authorization process maintains service availability for legitimate users while ensuring security
Solution Approach 2:
The patent segments remote units into different categories: authorized aerial vehicles, unauthorized aerial vehicles, and ground-based remote units. Each segment receives appropriate network access treatment. Authorized aerial vehicles are segmented into a privileged group that receives full access, while unauthorized aerial vehicles are segmented into a restricted group. This segmentation allows the network to maintain high service availability for authorized users while enforcing security restrictions on unauthorized users

AI summary
Apparatuses, methods, and systems are disclosed for aerial vehicle identification. One apparatus (300) includes a transmitter (310) that transmits (502) a request for information to a remote unit (102), wherein the information aids in identifying an unauthorized aerial vehicle. The apparatus (300) includes a receiver (312) that receives (504) a response to the request for information from the remote unit (102). The apparatus (300) includes a processor (302) that determines (506), based on the information, whether the remote unit (102) is part of an unauthorized aerial vehicle. In response to determining that the remote unit (102) is part of an unauthorized aerial vehicle, the transmitter (310) transmits (508) an indication to a base unit indicating that the remote unit is part of an unauthorized aerial vehicle.
