Apparatus and method for managing an access mode of a node B in a wireless communication system

A method for changing an access mode by a node B (NB) of a wireless communication system, the method comprising:

• receiving, from a core network or another NB, a request message requesting to change the access mode of the NB from a first mode into a second mode or from the second mode into the first mode, wherein the first mode allows access only to users or terminals having a registration in the NB, and the second mode allows access to users or terminals regardless of the registration in the NB;
• determining to change the access mode;
• transmitting, to the core network or the another NB, a response message informing of an access mode control result;
• if the access mode of the NB is changed from the first mode to the second mode, further granting access to at least one user or terminal not registered in the NB;
• and
• if the access mode of the NB is changed from the second mode to the first mode, controlling at least one user or terminal not registered in the NB to handover to a neighbor NB.
