A wireless communication system and handover method for the wireless
communication system are provided. A handover method for a wireless
communication system including a plurality of femto cells and at least
one macro cell within which the femto cells are disposed includes
determining, at a Radio Network Controller (RNC), a handover of a
terminal to a femto base station based on a measurement report of the
terminal and preset handover parameters, sending a radio link setup
request message to a femto base station gateway, the radio link setup
request message including a uplink scrambling code and an International
Mobile Subscriber Identity (IMSI) of the terminal and a Logical Cell
Identifier (LCID) of femto base stations reusing frequency of a macro
base station, searching, at the femto base station gateway, for femto
base stations of which LCIDs match the LCID contained in the radio link
setup request message, and performing, when only one LCID-matched femto
base station is discovered, the handover of the terminal to the
LCID-matched femto base station.
