Solution Overview
Problem
Current cellular network technologies lack a solution for obtaining and transmitting UAV flight path information, which hinders the provision of effective network services to unmanned aerial vehicles (UAVs).
Innovation Solution
A method and apparatus that enable a source base station to obtain and transmit UAV flight path information to a target base station via X2 or S1 interfaces, allowing the target base station to predict UAV movement and provide improved network services by integrating flight path information into handover signaling protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight path information is not transmitted between base stations, then the network service provision for UAV is simplified, but the service quality and prediction capability are degraded
Solution Approach 1:
The source base station performs preliminary action by obtaining and preparing the flight path information before the handover occurs. This information is then transmitted to the target base station in advance, enabling the target base station to predict UAV movement and prepare appropriate network resources, thereby improving service quality without adding complex real-time processing requirements during handover.
Solution Approach 2:
The patent introduces flight path information as an intermediary element that mediates between the source base station and target base station during handover. This intermediary carries essential UAV movement predictions, allowing both base stations to coordinate network resources effectively without requiring complex direct communication protocols or real-time processing during the handover event.
2Measurement precision
If flight path information is obtained and transmitted between base stations, then the prediction capability of UAV movement is improved, but the system complexity increases
Solution Approach 1:
The patent makes the handover signaling protocol universal by integrating flight path information transmission into the existing handover procedure. The same signaling mechanisms used for traditional handover are reused to also carry flight path information, allowing the system to gain improved UAV movement prediction capability without creating separate complex signaling protocols or additional dedicated communication channels.

AI summary
The present disclosure provides an information transmission method and apparatus. The method is applicable to a source base station that currently provides network service to an UAV and the method includes: obtaining flight path information on the UAV; sending the flight path information to a target base station for the target base station to provide network service to the UAV according to the flight path information. In this way, the present disclosure can realize the transmission of the flight path information on the UAV between base stations, and can also improve the service quality of the target base station.
