The invention relates to a method and apparatus for obtaining a PCI (physical-layer Cell identity) total interference value on the basis of a same-frequency cell detection ratio. The method comprises the steps of: according to MR (Measurement Report) data, obtaining a same-frequency cell MR detection ratio; according to frequency-sweep data of a road, determining a main service road coverage cell; according to a total sampling point of the main service road coverage cell and a sub sampling point of a first RSRP (Reference Signal Receiving Power) difference in a preset range, obtaining a same-frequency cell road detection ratio; determining the maximum value of the same-frequency cell MR detection ratio and the same-frequency cell road detection ratio as a same-frequency cell detection ratio of a same-frequency adjacent cell of a service cell, which is detected by the service cell; according to the same-frequency cell detection ratio and a PCI interference coefficient, obtaining the PCI total interference value of the service cell. The method and apparatus disclosed by the invention can effectively overcome the defect that an exiting PCI quality evaluation method is excessively mechanical and one-sided.
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 detection ratio of same-frequency cells and a method for obtaining PCI interference values based on the detection ratio of same-frequency cells. 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 all adjacent cel...
