Summary:PURPOSE: A method for controlling indoor handover in a mobile internet system made of indoor/outdoor base stations is provided to limit a candidate handover object base station as an indoor base station during handover between indoor base stations. CONSTITUTION: When a terminal moves outdoor, an indoor serving base station performs handover to an indoor target base station having signal intensity which is stronger than a handover reference value among indoor candidate base stations based on signal intensity measured by searching an adjacent base station in the terminal. The indoor serving base station sends a MOB HO-IND message to finally notify handover(909). Immediately, the handover is performed(910~916).
