Abstract: PURPOSE: An admission control method of a hybrid femto cell is provided to effectively control interference between MS terminals by utilizing the acceptance control method of a hybrid femto cell. CONSTITUTION: When an MS(Mobile Station) terminal is not belong to CSG(Closed Subscriber Group), a core network determines speed information for the MS terminal(S410, S430). When the speed information is not included, the core network gives the lowest set probability value to the MS terminal(S450). When the speed information is included, the core network gives a probability value in a range between the lowest set probability value and the highest probability value to the MS terminal(S440). The core network finally determines acceptance for a portable terminal(S460).
