<p>The present invention relates to a system and a method for detecting a physical cell identifier (PCI) collision, which can detect the PCI collision regardless of establishment of X2 link and can extract a cell causing a collision according to the collision between cells using different frequencies and the necessity of taking an emergency measure, thereby providing the high-efficiency stabilization of a system and a reliable service by allowing a user to take a measure in advance for a cell requiring a quick measure by the user. The method for detecting a PCI collision according to the present invention comprises: a step of collecting neighbor relation information of multiple cells; a confusion detection step of checking a reference cell which is a cell of the multiple cells recorded on the neighbor relation information and whether there exists a cell using an identical physical cell ID within a coverage of the reference cell; a collision detection step of determining whether there exists a cell being in neighbor relationship, which uses the identical physical cell ID, among the cells; and a step of extracting the cells detected in the confusion detection step or collision detection step and providing information on the extracted cells to a user.</p> |
