TERMIANL, METHOD FOR HANDOVER OF THEREOF AND SUPPORTING METHOD FOR HANDOVER OF BASE STATION

摘要

PURPOSE: A terminal, a method for handover thereof, and a supporting method for the handover of a base station are provided to efficiently generate and manage a neighboring base station list including femto cell information in order for a terminal to perform a handover process in a condition in which a plurality of femto cells and macro cells are superimposed. CONSTITUTION: A macro base station(100) manages a macro cell(10). The macro cell includes a plurality of femto cells(21,22,23) managed by the plurality of femto base stations(210,220,230). The macro cell represents a cell that is larger than the femto cell. The femto base stations represent very small base stations for providing a wireless communication service to small areas and manage the femto cell. For example, they are installed in a blanket area where propagation of other cells is degraded such as a house or a building to acquire a high quality mobile communication service. A terminal(300) represents the end terminal of a radio channel and accesses the femto base stations or the macro base station to transmit/receive data. The terminal performs a scan process based on the neighboring base station list broadcast by the macro base station. The terminal acquires measurement information on the neighboring macro base stations through the scan process. The measurement information includes information that can influence the handover such as RSSSI(Received Signal Strength Indicator), CNR(Carrier to Noise Ratio), and SINR(Signal to Interference Noise Ratio).
