Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of maintaining good communication performance between drones and network devices, such as base stations, is critical due to the increasing use of drones, which often experience signal interference and handover failures.
Innovation Solution
Generating and reporting flight path information by drones to network devices, including location information of target nodes, enables network devices to plan optimal handovers and improve communication success rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detailed flight path information with multiple target nodes is reported, then handover success rate is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential location information of target nodes from complete flight path data. Instead of reporting all flight path details, the terminal device identifies and reports only the critical target nodes that affect handover decisions, thereby reducing signaling overhead while maintaining handover success rate.
Solution Approach 2:
The patent applies partial action by reporting a subset of flight path information rather than complete data. The terminal device determines a reduced set of target nodes based on predefined criteria (such as signal strength thresholds or geographic boundaries), providing just enough information for effective handover without excessive signaling.
2Reliability
If flight path information is reported frequently, then communication performance is improved, but network resource consumption increases
Solution Approach 1:
The patent implements periodic reporting where the terminal device sends flight path information at predetermined intervals or when specific conditions are met (such as entering predefined geographic areas or detecting signal threshold changes). This periodic action ensures communication performance is maintained while avoiding excessive network resource consumption from continuous reporting.
3Reliability
If complete flight path information is reported, then network device can optimize handover, but processing complexity increases
Solution Approach 1:
The patent extracts only the necessary target node location information from complete flight path data. The terminal device identifies key target nodes based on criteria such as signal strength, geographic boundaries, or handover thresholds, and reports only these essential points to the network device, reducing processing complexity while enabling effective handover optimization.

AI summary
This application provides a wireless communications method and apparatus, to implement good performance of communication between a terminal device and a network device. The wireless communication method includes: generating flight path information, where the flight path information includes location information of at least one target node on a flight path; and sending the flight path information. Therefore, a target network device can determine, based on flight path information reported by the terminal device, a flight path along which the terminal device is to fly, and the target network device may determine, based on the future flight path, at least one network device serving the terminal device. Based on this, a success rate of handover of the terminal device in a network is improved; in this way, good performance of communication between the terminal device and the network device is implemented.
