Abstract: PURPOSE: A handover method between the femtocell base stations is provided to minimize data delay in handover. CONSTITUTION: A data transmission channel is formed between an S-FGW(Source-Femto cell GateWay)(210) and a T-FGW(Target-FGW)(220)(S213). The S-FGW manages S-FBS(Source-Femto cell Base Station). The T-FGW manages T-FBS. Data communication is executed between the S-FGW and the T-FGW through the data transmission channel. After the S-FGW receives a handover response message from the T-FGW, the data transmission channel is executed.

Abstract: PURPOSE: A closed base station and operation method of non-subscribers are provided to increase the utilization ratio of wireless resources by avoiding interference states of a non-subscriber terminal for an adjacent closed mode minimum base station. CONSTITUTION: A closed BS establishes interference preamble for interference state notification through system information broadcast(S61). When the interference preamble appointed by a non-subscriber terminal within a service area is transmitted, the closed base station inspects a current service state(S66). The closed base station avoids interference situations by controlling power and by inducing the non-subscriber to execute handover according to the inspected current service state(S613,S614).
