Selecting a candidate neighbor method and system

The invention discloses a method and system for selecting candidate neighbor cells, belonging to the field of network communication. The method comprises the steps of: 101, determining a candidate cell set of a master cell; 102, obtaining a base station closest to the master cell from the candidate cell set, adding all cells within the base station into a neighbor cell set; 103, deleting the cells shielded by the base station in the candidate cell set and the cells included in the neighbor cell set; 104, judging whether the candidate cell set is empty or not, if not, repeating the steps 102, 103 and 104; and 105, if the candidate cell set is empty, taking the cells in the neighbor cell set as a first-layer neighbor cell of the master cell. According to the technical scheme disclosed by the invention, neighbor cell planning efficiency and accuracy can be increased, neighbor cell resources can be saved and the adaptivity of candidate neighbor cells can be increased.
