Abstract

The invention provides a site selection optimization method for 5G base stations in urban space considering the signal blocking effect, constructs an artificial immune intelligent optimization model of 5G communication base stations, and optimizes the number of communication base stations under the premise of considering the blocking effect of urban buildings on communication signals and spatial layout to achieve reasonable control of the number of base stations and the maximization of their signal coverage. The present invention adopts the CSA algorithm as the optimal decision-making algorithm, and aims at the basic characteristics and solution requirements of the spatial layout optimization problem of the 5G communication base station, and proposes a space layout optimization technology with high calculation efficiency and strong result feasibility, and realizes the automation of the 5G communication base station and intelligent spatial layout and site selection; the present invention effectively improves the service quality of 5G signals by using GIS technology to couple multi-source geographic data and spatial optimization decision-making methods, reduces the cost of base station deployment and construction and the economic cost of base station operation, and provides future 5G communications Base station planning and construction provide decision-making basis and technical support.

Description

technical field [0001] The invention belongs to the technical field of space deployment of communication base stations, and in particular relates to a site selection optimization method for 5G base stations in urban space considering the signal blocking effect. Background technique [0002] 5G communication technology, also known as the fifth generation mobile communication technology (5th generation mobile networks or 5th generation wireless systems, 5th-Generation, referred to as 5G or 5G technology), is the latest generation of cellular mobile communication technology. Compared with the existing 2G, 3G and 4G communication technologies, 5G communication technology has made a qualitative leap in terms of data transmission rate, reduced data delay, energy saving, and improved system capacity. Therefore, the development of 5G technology is of great significance to the development of Internet of Vehicles, autonomous driving, and artificial intelligence technology. In recent ...
