The method is simple in steps and convenient to operate and can efficiently and accurately optimize the base station antenna parameters so that the network coverage quality of the area of poor coverage quality can be improved and the method is suitable for popularization and application.

Description

technical field [0001] The invention relates to an optimization method, in particular to a multi-mode and multi-objective LTE base station antenna optimization method with limited parameter adjustment. Background technique [0002] Since LTE was formulated as a global standard by the 3GPP organization, the LTE network has developed rapidly. Up to now, the LTE network has covered a wide range of areas at home and abroad, and has become a vital part of the mobile communication network field. However, with the deepening of LTE's comprehensive commercial use, the increase of base station antennas, changes in the surrounding environment of base stations, and unreasonable planning and layout in the early stage have led to areas with poor coverage quality in the actual network. For areas with poor network coverage, the network is usually improved by adjusting base station antenna parameters. However, the traditional method of optimizing base station antenna parameters is mainly ba...

However, with the deepening of the comprehensive commercial use of LTE, the increase of base station antennas, changes in the surrounding environment of the base station, and unreasonable planning and layout in the early stage have led to areas with poor coverage quality in the actual network.

For areas with poor network coverage, the network is usually improved by adjusting the antenna parameters of the base station. However, the traditional method of optimizing the antenna parameters of the base station is mainly based on the experience of engineers. This solution has low efficiency and low accuracy. Poor, it is obviously difficult to meet the requirements of current base station antenna optimization
