1. A Physical Cell Identifier (PCI) collision detection method in a first network node, comprising:
receiving cell information of a second cell generated by a second network node, wherein the cell information comprises PCI of the second cell and position information of the second network node; and
when it is judged that the second network node is within a zone around the first network node based on the position information, determining whether a PCI of a first cell generated by the first network node is same as the PCI of the second cell.
