Claim Text:
1. A method for changing an access mode of a second node B (NB), by a core network (CN), in a wireless communication system, the method comprising: receiving, from a first NB, a request to change the access mode of the second NB from a first mode into a second mode or from the second mode into the first mode; determining, by the CN, to change the access mode of the second NB; transmitting, to the second NB, a request message requesting to change the access mode of the second NB; and receiving, from the second NB, a response message informing of an access mode control result, wherein the first mode allows access only to users or terminals having a registration in the second NB, and the second mode allows access to users or terminals, regardless of the registration in the second NB, wherein, if the access mode of the second NB is changed from the first mode to the second mode, the second NB further grants access to at least one user or terminal not registered in the second NB, and wherein, if the access mode of the second NB is changed from the second mode to the first mode, the second NB controls at least one user or terminal not registered in the second NB to handover to a neighbor NB.
