1. A method for user relocation, the method comprising steps of: receiving, by a Home NodeB (HNB) to which a User Equipment (UE) belongs, a relocation request message transmitted from a Home NodeB Gateway (HGW), the relocation request message including an indication that an access control list is to be updated or changed, where a relocation of the UE is triggered by an access control list update request transmitted to the HGW by an HNB configuration server; determining, by the HNB, whether or not the UE is currently using a service on the HNB when the relocation request message is received from the HGW; identifying, by the HNB, that the UE is capable of being relocated to a macro NodeB, if the UE is currently using the service on the HNB; performing, by the HNB, a relocation procedure to relocate the UE by configuring resources for the relocation with the macro NodeB, if the UE is capable of being relocated to the macro NodeB; and transmitting, by the HNB, a relocation response message corresponding to the relocation request message to the HGW, after performing the relocation procedure.
