APPARATUS AND METHOD FOR HANDOVER BETWEEN MACRO CELL AND HOME CELL IN MOBILE COMMUNICATION SYSTEM

摘要

A handover apparatus between a macro cell and a home cell in a mobile communication system and a method thereof are provided to enable a user terminal to determine whether a home base station exists around itself in a 3GPP LTE system, and perform gap assisted measurement only when the user terminal enters the coverage of the home base station. A user terminal(330) can move into the coverage of home base stations(310,320) while receiving a call service from a base station(300). For the above step, the user terminal performs gap assisted measurement for the handover from the macro base station to the home base station. When the user terminal enters the coverage of the home base station, to sense the entry fact, the home base station is switched to an FA of the base station to transmit an advertisement signal. When the home base station is driven, it receives the resource allocation information for the advertisement from a base station to which the home base station belongs.
