A location information-based selection method for UAV cellular communication base stations

Abstract

The invention belongs to the technical field of unmanned aerial vehicle communication, and discloses an unmanned aerial vehicle cellular communication base station selection method based on position information, which comprises the following steps: S1, building a hybrid base station; s2, constructing a cellular communication network; s3, the unmanned aerial vehicle obtains the longitude, latitude,height and timestamp of the unmanned aerial vehicle in each time slice; s4, taking the hybrid base station in the communication range of the unmanned aerial vehicle as a communication base station, and sending a telemetry frame to the communication base station by the unmanned aerial vehicle; s5, counting the distance by the communication base station; s6, the communication base station sends a distance statistics frame to the console in each time slice; s7, the console marks an active base station and an inactive base station of the unmanned aerial vehicle according to the accumulated distance of the sliding window; s8, the console notifies the movable base station to switch to the current movable base station; and S9, entering the next time slice to accumulate the distance of the next round of sliding window. The method is wide in communication range, and solves the problem of selection of the most suitable base station by the unmanned aerial vehicle in a sliding window distance accumulation mode.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication, and in particular relates to a method for selecting a base station for unmanned aerial vehicle cellular communication based on position information. Background technique [0002] With the development of drone technology, drones are no longer simply used in film and television shooting, miniature selfies, etc., in agriculture, logistics, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, etc. There are applications in various fields, and the problem of medium and long-distance UAV measurement and control has also attracted more and more attention. [0003] Due to the limitations of the communication system, ground communication networks (such as 4G, WiFi, etc.) cannot be applied to the field of UAV measurement and control. The channel modes currently used for UAV measurement and control inc...
