Drone Session Connectivity for Aerial State Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial UAVs face communication range restrictions due to direct line-of-sight signal transmission and introduce interference to ground UEs when using cellular connections, while uncertified or unauthorized drones may also cause interference, and existing methods struggle to accurately detect aerial states for applying appropriate radio protocols.
Innovation Solution
Implementing session connectivity to trigger appropriate radio protocols for drone-coupled wireless devices by establishing an aerial state session within the network, using triggers such as operational, flight, or communication state changes, and managing bearers and protocols accordingly.

1Length of stationary object
If UAVs use cellular connections for communication, then communication range is extended beyond direct line-of-sight, but interference is introduced to ground UEs
Solution Approach 1:
The system dynamically switches communication modes based on UAV flight state. When the UAV is on the ground, it uses standard cellular connections. When the UAV takes off, it transitions to a different communication mode (such as direct connection or specialized aerial protocol) to reduce interference to ground UEs while maintaining communication capability.
Solution Approach 2:
The network changes communication parameters based on UAV detection. When an aerial state session is detected, the network applies different radio protocols, power control schemes, and resource allocation parameters specifically optimized for aerial vehicles, thereby reducing interference to ground-based user equipments while maintaining extended communication range.
2Object-generated harmful factors
If appropriate radio protocols are applied for aerial state, then interference to ground UEs is reduced, but complexity of detecting and measuring aerial state increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the UAV itself reports its flight status to the network. The UAV-coupled wireless device detects its own aerial state (using sensors or communication state indicators) and informs the network, which then applies appropriate radio protocols. This shifts the detection complexity from the network to the UAV device.
Solution Approach 2:
The system uses feedback from the UAV about its operational state (aerial or ground-based) to trigger appropriate radio protocols. The UAV continuously reports its status, and the network responds by applying the correct communication mode, creating a closed-loop system that adapts to the UAV's state without requiring complex network-side detection.
3Productivity
If session connectivity is established for aerial state, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The system establishes session connectivity in advance based on predicted aerial state. When the UAV indicates it is about to take off or enters aerial mode, the network pre-establishes the appropriate communication session and parameters, so that when the UAV needs to communicate efficiently in aerial mode, the session is already ready, reducing latency and improving efficiency without requiring complex real-time decisions.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) configured as a drone-coupled wireless device may be configured to transmit a message indicating information relating to the drone-coupled wireless device (e.g., aerial state, non-aerial state, airborne status, drone capability, quality of service (QoS) requirements of a drone service) to a base station. The message may also carry a session connectivity request, which the base station may use to determine that the UE is a drone-coupled wireless device, establish a bearer appropriate for a subscription service of the UE (e.g., as indicated by the drone capability), and apply appropriate protocols for the UE.
