Claim:
A method for transmitting a neighbor cell identification of a neighbor cell in a mobile communication system, the method comprising: transmitting a neighbor cell identifier comprising information regarding a type of the neighbor cell to a user equipment (UE); and performing access control for the UE based on an identification result of the UE for the neighbor cell, the neighbor cell comprising one of a macro cell and a femtocell, the femtocell configured to selectively operate in a plurality of access modes, the plurality of access modes comprising a closed access mode in which the femtocell serves only registered UEs, an open access mode in which the femtocell serves both registered UEs and non-registered UEs, and a hybrid access mode in which the femtocell can be operated in either of the closed access mode and open access mode, wherein transmitting the neighbor cell identifier comprises: determining, when the femtocell operates in the hybrid access mode, whether a registered user equipment is present in a service area; transmitting, when a registered user equipment is not present in the service area, by the femtocell, a neighbor cell identifier indicating the open access mode; and activating, when a registered user equipment is present in the service area, by the femtocell, the closed access mode and transmitting a neighbor cell identifier indicating the closed access mode.
