Abstract

The invention discloses a method and a system for configuring antenna parameters. In the network plan period, the method comprises the following steps of: setting the initial value of the antenna parameters of a network cell, the target threshold of the antenna parameters of the cell and the optimal constraint condition; building a simulation platform, using the simulation platform for carrying out simulation on the initial value of the antenna parameters and obtaining the simulation results; configuring the initial value of the antenna parameters into the antenna parameters of the cell when the simulation results meet the target threshold; adopting the genetic algorithm for carrying out the optimization in the constraint condition on the antenna parameters when the simulation results do not meet the target threshold until the simulation results meet the target threshold or reach the maximum iteration number of the genetic algorithm; and configuring the antenna parameters obtained through the optimization into the antenna parameters of the cell. Compared with the manual plan adopted in the conventional method, the method and the system have the advantages that the work cost of the wireless network plan can be greatly saved, and the efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of network planning and management, in particular to a method and system for configuring antenna parameters. Background technique [0002] Antenna parameters (also called radio frequency parameters or RF parameters) include downtilt, azimuth and pilot power. Antenna parameters have an important impact on network performance, mainly in the following aspects: [0003] 1. Network coverage [0004] Operators always hope to provide sufficient coverage area under a given site scale. For base stations using directional antennas, the azimuth angle of the antenna determines the radiation direction of its main lobe radio waves. dense places, while minimizing the interference to adjacent cells; and the antenna downtilt of a cell has a direct impact on the coverage area of ​​the cell, the smaller the downtilt, the larger the coverage area, but at the same time it will cause The interference to other adjacent c...
