Problems solved by technology

This method is based on the topology method divided into different time slots, and the flight path is determined in sections during signal transmission. In this way, the calculation of the path is affected by the signal transmission quality in the first and second time slots, and the real-time calculation of the path cannot be guaranteed.
[0004] In addition, when UAVs and ground users use TDMA (Time division multiple access, time division multiple access) access method, the longer the TDMA access cycle, the UAVs have enough time to get close to ground communication users to obtain better communication channels And higher throughput, but on the other hand, the larger the period, the longer the waiting time for each ground user, the greater the delay of the system

Abstract

The invention discloses a control method of an unmanned aerial vehicle base station communication system and a storage medium. The method comprises steps of establishing a communication model of an unmanned aerial vehicle and a user terminal, wherein the communication model comprises a flight path shown in the description in a flight period of the unmanned aerial vehicle and a communication time sequence shown in the description of the user terminal and the unmanned aerial vehicle in the flight period; by use of the communication model, acquiring the biggest communication speed corresponding to the user terminal in the flight period, wherein the biggest communication speed corresponding to the ith user terminal; and establishing a target function shown in the description, wherein a formulais shown in the description, and calculating the target function so as to obtain an optimal solution of the target function. According to the invention, the optimal solution of the target function isfinally obtained and comprises an optimal selection of the flight path of the unmanned aerial vehicle and the communication time sequence; the target function is used for controlling the unmanned aerial vehicle base station; according to the flight routes of the unmanned aerial vehicle, the accessing sequence and duration of the user can be flexibly dispatched; and performance of the communication system can be optimized by use of the mobility of the unmanned aerial vehicle.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicle communication, in particular to a control method, system, device and storage medium of an unmanned aerial vehicle base station communication system. Background technique [0002] Unmanned Aerial Vehicles (UAVs, unmanned aerial vehicles) are widely used in military and civilian fields because of their low cost, good maneuverability, and convenient use. In recent years, they have played an increasingly important role in these fields. Among them, the UAV base station communication system established around the UAV as the air mobile base station can provide better communication services for ground communication terminals, which not only expands the communication coverage, but also improves the performance of the communication system. [0003] Patent CN201710276185.7 "Track Optimization Method for UAV Relay Broadcast Communication System" proposes a UAV segment topology method for communi...
