Embodiment Construction

[0110] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0111] It should be noted that when the grid is performed, the geographical location of a cell is located in a grid, which does not mean that the signal of the cell must also be located in a grid. If the signal of a cell is not completely located in a grid, when calculating the sampling value of the cell, it is necessary to calculate the sampling value of the cell as the main cell and the sampling value of the cell as the neighboring cell in each grid, and then divide each The sum of the sampled values ​​of the cell as the main cell in each grid is taken as the sampled value of the cell ...

Abstract

The embodiment of the invention relates to the technical field of communication, and particularly relates to a method and apparatus for screening a site location of an FDD-LTE base station. The method comprises the following steps: collecting MR data generated by m main cells of an existing base station of an existing network, performing equivalence or prediction on a common-address base station or a newly added base station to obtain MR of the m main cells after the FDD-LTE base station is constructed, determining the interference contribution coefficients of the m main cells in the simulative FDD-LTE base station according to the MR of the m main cells after the FDD-LTE base station is constructed, and determining whether to set the FDD-LTE base station within the m main cells according to the interference contribution coefficients of the m main cells in the simulative FDD-LTE base station. As the MR data are measurement reports reported by the terminal in a communication process, the actual wireless environment of the user can be reflected, thereby having certain superiority to serve as evaluation data sources, and accordingly the cost of network optimization and transformation after the construction of the base station can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and device for screening FDD-LTE base station sites. Background technique [0002] Traditional LTE (Long Term Evolution, Long Term Evolution) site planning mainly starts with coverage planning and capacity planning. On the one hand, the cell radius of the selected standard and frequency band in the corresponding wireless scenario is calculated through the uplink and downlink budget. The demand forecasts the number of base stations and carrier sectors required to obtain the site size of the base station, and then conducts detailed base station site planning through coverage and business simulation. [0003] From the traditional LTE network construction and optimization experience, LTE is a co-frequency system, and the overlapping coverage caused by interference has a great impact on network performance. In addition, interference is also the main rea...
