Air base station data transmission method, device, equipment and system

Abstract

The embodiment of the invention provides an air base station data transmission method, device, equipment and system, applied to a first air base station. The method includes the following steps: acquiring the air link quality of the first air base station; when determining that the air link quality of the first air base station is lower than the preset air link quality, obtaining the air link quality of each air base station in a preset air base station set; determining whether effective air base stations exist in the air base stations adjacent to the first air base station according to the air link quality of each air base station in the preset air base station set; and if yes, determining a target air base station in the effective air base stations of the adjacent air base stations according to a first preset selection rule, and transmitting a first data return request to the target air base station, wherein the first data return request is used for enabling the target air base station to send target data to a ground station within the communication range of the target air base station. Thereby, the reliability of data transmission of the air base station can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data transmission method, device, device, and system for an air base station. Background technique [0002] Aerial base stations refer to base stations built in the air from several thousand meters to tens of kilometers. Air base stations are usually set up on platforms that can stay in the air. The platforms that stay in the air can be balloons, airships, airplanes, etc. [0003] There are multiple ground stations on the ground, and the air base station can communicate with the core network through the ground stations within its communication range. Specifically, the base station in the air determines a ground station within its communication range, sends data to a ground station within its communication range, and sends the data to the core network through the ground station. Since there is wireless communication between the air base sta...

Problems solved by technology

However, the size of high-frequency wireless wavelengths and airborne particles (for example, fog droplets, raindrops, etc.) is relatively close. There is a large attenuation in the air base station, resulting in poor data transmission quality of the base station in the air

[0004] In the prior art, when the air base station fails to send data to a ground station within its communication range, the air base station sends data to other ground stations within its communication range. However, due to different ground stations within the communication range of the same air base station The distance between stations is usually small (up to tens of kilometers), and the correlation of weather space is high, so that the channel quality between the same air base station and different ground stations within its communication range is relatively similar

Therefore, when the air base station fails to transmit data to a ground station within its communication range, the success rate of data transmission to another ground station within its communication range is not high, so that the data transmission quality of the air base station is still poor, resulting in The reliability of air base station transmission data is poor
