摘要
Provided is a method performed in a small cell to avoid PCI collisions in a mobile communication network. The method comprises the steps of: (i) counting the number of suspected collisions based on RRC re-establishment messages (RRE messages) received from at least one terminal; and (ii) adding a physical cell identifier (PCI) of the small cell to a collision suspect PCI list when the number of suspected collisions is greater than a predetermined threshold and reselecting a PCI for the small cell, wherein step (i) of counting the number of suspected collisions includes increasing the number of suspected collisions by one when UE context about a UE which has transmitted each of the RRE messages does not exist in the small cell and a cause of the corresponding RRE message is other failure.
