Abstract

In order to manage a neighbor list of neighboring base stations based on the location of a terminal communicating with a base station of a macrocell with femtocell deployments, the base station divides the macrocell in accordance with a predetermined standard of division, and generates a mobile neighbor advertisement message so as to periodically transmit the generated message to the terminal. At this time, the terminal identifies the current location thereof in the macrocell upon receipt of the pilot signals periodically transmitted from the base station of the macrocell. The terminal obtains information regarding the location of the terminal from the information regarding the femtocells deployed within the respective divided regions and information regarding macrocells neighboring the macrocell through using the mobile neighbor advertisement message to scan base stations.
