Abstract

The present invention provides a method and device for optimizing and analyzing an LTE network structure, by constructing a downlink interference matrix and an uplink interference matrix, wherein the downlink interference matrix includes elements for analyzing the weak coverage of a cell, based on the downlink interference matrix and the uplink interference matrix The weak coverage degree of each cell, the downlink interference coefficient and uplink interference coefficient of mutual interference between each two cells are respectively obtained, and the network problems are analyzed based on the above parameters, so that the downlink network structure and the uplink network are considered in the analysis process Structure problems, and at the same time combine the coverage of inter-cell signals and the interference of inter-cell signals to formulate network optimization strategies, without multiple rounds of optimization and adjustment, and can more accurately analyze the real cause and root cause of network problems, improving the network Optimized quality and efficiency.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more particularly, to a method and device for optimizing and analyzing an LTE network structure. Background technique [0002] The quality of 4G network coverage is directly related to user experience, and is the most concerned issue for operators in the process of network construction and optimization. The ideal network coverage goal is seamless coverage, that is, the overlapping area between cells can be at a lower level under the premise of ensuring user mobility. However, when the network structure is unreasonable, network structure problems such as overlapping coverage, over-coverage or weak coverage are prone to occur. Therefore, it is necessary to use scientific means to evaluate the network structure and find out the problem cells for optimization and adjustment. [0003] The existing network structure evaluation and optimization methods generally evaluate and score...

Problems solved by technology

[0004] However, the current optimization is often optimized and adjusted for a single coverage or interference, and this adjustment may have a negative impact on other indicators of the network structure. To achieve a balance between multiple optimization objectives, usually through multiple rounds of adjustments In order to achieve the purpose of optimization; and the current optimization only considers the problem of the downlink network structure or only the uplink network structure, and cannot accurately analyze the real cause and root cause of the network problem
