Abstract: An apparatus and a method for a terminal handover between systems using different Frequency Allocations (FAs) are provided. The method includes broadcasting an indication signal to inform of existence of the terminal in a coverage of a macro base station to which an indoor base station is registered; and when receiving a handover command message of the indoor base station, from the macro base station, performing a handover procedure to the indoor base station. The base station can efficiently utilize the control channel resource and the user terminal needs not to conduct the unnecessary scanning procedure. Thus, the time and the power required for the scanning can be spared.
