Claim:
1. An apparatus for selectively providing system information in a heterogeneous network environment including a first network overlaid on a second network, the apparatus comprising: a location determination unit configured to receive an uplink signal transmitted from user equipment and to determine a first network base station in the first network, which is closer to the user equipment, as compared to other first network base stations in the first network; a mapping table configured to store information on at least one second network cell in a second network, which is overlaid on a first network cell of the determined first network base station, and is spatially in a comparatively close distance to the determined first network base station in the first network among, as comparted to other second network cells overlaid on the first network cell of the determined first network base station; and a signal processor configured to determine, among the entire second network cells overlaid on the first network cell of the determined first network base station, at least one second network cell spatially close to the determined first network base station based on the mapping table, to obtain system information of the determined at least one second network cell.
