Solution Overview
Problem
Current communication technologies do not provide an appropriate method for unmanned aerial vehicles (UAVs) to send their path information to base stations, limiting effective communication and resource allocation.
Innovation Solution
A method and apparatus for UAVs to send path information to base stations, involving the exchange of indication and configuration information to determine capability and permission, with optional preparation information for communication connection establishment, using signaling elements like RRCConnectionReconfiguration and UE-EUTRA-Capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UAV communication functions are added, then communication capability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by enabling UAVs to use existing base station communication infrastructure and signaling protocols (RRCConnectionReconfiguration, UE-EUTRA-Capability) already designed for terrestrial devices. The UAV communicates path information using standardization communication procedures, allowing the same communication system to serve both traditional user equipment and UAVs without requiring entirely new dedicated communication mechanisms.
Solution Approach 2:
The patent introduces an intermediary approach by using base stations as mediators between UAVs and the network core. The base station receives path information from UAVs, processes it through existing communication protocols, and forwards it to the network. This intermediary layer allows UAV communication to be achieved without directly modifying core network architecture, thereby reducing overall system complexity.
2Productivity
If path information transmission protocol is established, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The patent merges path information transmission with existing RRC (Radio Resource Control) signaling procedures. By combining the path information reporting function with established RRCConnectionReconfiguration and UE-AssistanceInformation signaling mechanisms, the system achieves efficient UAV communication without creating separate complex protocols. The path information is integrated into existing message structures, reducing the need for additional signaling overhead.
Solution Approach 2:
The patent makes existing communication signaling elements multi-functional by enabling them to carry both traditional communication data and UAV-specific path information. The UE-EUTRA-Capability signaling and RRCConnectionReconfiguration messages are extended to include path information fields, allowing a single signaling mechanism to serve multiple purposes: standard communication setup and UAV path reporting, thereby improving efficiency without proportionally increasing complexity.

AI summary
The present disclosure relates to a method of obtaining path information of an unmanned aerial vehicle (UAV). The method is applicable to a base station, and includes: receiving indication information from the UAV, where the indication information indicates whether the UAV has a capability of sending the path information; if the UAV has the capability of sending the path information according to the indication information, sending configuration information to the UAV, where the configuration information indicates whether the UAV is allowed to send the path information to the base station; and if the UAV is allowed to send the path information to the base station, receiving the path information from the UAV. According to examples of the present disclosure, the base station successfully receives the path information from the UAV.
