A communication network hotspot area capacity enhancement-oriented multi-air base station deployment method

Abstract

The invention provides a communication network hotspot area capacity enhancement-oriented multi-air base station deployment method, which comprises the following steps: obtaining the state information of a target area, wherein the state information of the target area comprises the current geographic position information of a user terminal in the target area and the current geographic position information of an air base station in the target area; dividing cooperative clusters for the air base stations based on an affinity propagation AP clustering algorithm, the interference intensity between the air base stations and the state information of the target area to obtain a first user air base station association set; calculating a first system capacity based on the first user air base station association set, and setting the first system capacity as a reward function of a multi-agent deep reinforcement learning DQN network; using the air base station as an independent agent, determining the action of each agent according to the DQN network, and moving the position of the air base station according to the action; through at least one time of position movement, obtaining the air base station deployment position of the target area, and improving the capacity performance of the system.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multi-air base station deployment method for capacity enhancement in communication network hotspot areas. Background technique [0002] With the development of the mobile Internet, people have higher and higher requirements for communication experience in various application scenarios.
