The invention relates to a method and device used for acquiring a PCI total interference value based on a co-frequency cell correlation coefficient. The method comprises the steps that co-frequency cell MR detection ratio is acquired according to MR data; a main service road coverage cell is determined according to road sweep frequency data; according to the total sampling point of the main service path coverage cell and sub sampling points of a first RSRP difference value within a preset range, the co-frequency cell road detection ratio is acquired; the co-frequency cell MR detection ratio and the maximum value in the co-frequency cell road detection ratio are determined as the co-frequency cell detection ratio; the cut-off ratio is acquired; according to the co-frequency cell detection ratio and the cut-off ratio, the co-frequency cell correlation coefficient is acquired; and the service cell PCI total interference value is acquired according to the co-frequency cell correlation coefficient and a PCI interference coefficient. According to the invention, the defect of mechanical and one-sided PCI quality evaluating method in the prior art can be effectively solved.
Description
technical field [0001] The present invention relates to the field of LTE (Long Term Evolution, long-term evolution of general mobile communication technology) network technology, in particular to a method for obtaining a PCI total interference value based on the same-frequency cell correlation coefficient and a method for obtaining the PCI total interference value based on the same-frequency cell correlation coefficient. means of the total disturbance value. Background technique [0002] PCI (physical-layer Cell identity, physical cell identity) is used to distinguish wireless signals of different cells, and the value range is 0-503. Currently, PCI planning generally follows the following constraints: [0003] (1) The PCI modulus 3 of different cells under the same base station is different, that is, mod(PCI1,3)≠mod(PCI2,3); [0004] (2) The residual values of PCI modulo 6 in adjacent cells are different, that is, mod(PCI1,6)≠mod(PCI2,6); [0005] (3) The PCIs between a...
