A base station selection method for UAV cellular communication based on sliding window counting

Abstract

The invention belongs to the technical field of UAV communication, and discloses a method for selecting a UAV cellular communication base station based on sliding window counting, comprising the following steps: S1, building a hybrid base station; S2, using the hybrid base station to construct a cellular communication network; S3, The drone sends telemetry frames to the communication base station; S4, each communication base station counts the number of telemetry frames received in the time slice; S5, the communication base station sends the telemetry counting frames of the drone to the console; S6, the console counts according to the sliding window, Mark the active base stations and inactive base stations of all drones; S7, the console notifies the active base station to switch to the current active base station of the drone; S8, enter the next time slice for the next round of sliding window counting. The invention uses hybrid base station cellular communication, which has a wide communication range and low use cost; at the same time, it uses the sliding window counting method to solve the problem of unmanned aerial vehicles selecting the most suitable base station, and greatly improves the measurement and control quality of unmanned aerial vehicles.

Description

technical field [0001] The invention belongs to the technical field of UAV communication, and in particular relates to a method for selecting a UAV cellular communication base station based on sliding window counting. 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 include satellite communication mode and rad...

Problems solved by technology

[0004] In order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a method for selecting a UAV cellular communication base station based on sliding window counting, and to use a hybrid base station cellular communication architecture to solve the problem that the UAV measurement and control range is too small in the radio communication mode solve the problem of high cost of satellite terminals in the satellite communication mode; UAVs can choose the most suitable base station for communication during flight, which solves the problem of handover during UAV flight and avoids the base station to control The station repeatedly transmits a large amount of invalid information, avoids traffic waste, and ensures the quality and efficiency of information transmission
