Method and device for user access and content caching of unmanned aerial vehicle communication network

Abstract

The invention provides a method and a device for user access and content caching of an unmanned aerial vehicle communication network. The method comprises the following steps: randomly initializing user access and caching deployment; calculating optimal user access information under the current cache deployment condition according to the initialized cache deployment; calculating the optimal cachedeployment information under the current user access condition; taking the calculated cache deployment information as the input of a new round of iteration to calculate and obtain the optimal user access and cache deployment information of the next iteration period; repeating iteration until a preset iteration frequency threshold value is reached to obtain final optimal user access and cache deployment information; and calculating optimal backhaul link bandwidth allocation information according to the obtained optimal user access and cache deployment information, and finally obtaining an optimal access and cache scheme in the current unmanned aerial vehicle communication network. According to the method and device, the content acquisition time delay of the user in the unmanned aerial vehicle communication network can be reduced.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicle communication technology, and in particular to a method and device for user access and content caching of an unmanned aerial vehicle communication network. Background technique [0002] With the rapid development of mobile Internet and intelligent terminals, great opportunities have been brought to the network communication control of unmanned aerial vehicle (UAV), and the smoothness and flexibility of the network environment in the process of UAV control Waiting is even more important. The capacity pressure of the cellular network and the unprecedented increase of traffic congestion, especially in areas with highly dense user distribution (such as sports fields, etc.), the introduction of drones into the traditional cellular network can enable users to get closer to the base station than the ground base station. Therefore, capacity expansion can be flexibly realized and...
