Abstract

A method and an apparatus for setting up an X2 interface setup are provided. The method includes transmitting, by a first Base Station (BS), an X2 interface setup request to a second BS, wherein the X2 interface setup request comprises an access mode of a Closed Subscriber Group (CSG) supported by a cell in the first BS, and transmitting, by the second BS, an X2 interface response message to the first BS, wherein the X2 interface response message comprises the access mode of the CSG supported by the cell in the second BS.

Claims

1. A method for setting up an X2 interface in a mobile communication system, the method comprising:

transmitting, by a first Base Station (BS), an X2 setup request message to a second BS, wherein the X2 setup request message includes a Closed Subscriber Group (CSG) Identifier (ID) and neighbor information of the first BS; and

receiving, by the first BS, an X2 setup response message from the second BS, wherein the X2 setup response message includes a CSG ID and neighbor information of the second BS.

2. A method for setting up an X2 interface in a mobile communication system, the method comprising:

receiving, by a first Base Station (BS), an X2 setup request message from a second BS, wherein the X2 setup request message comprises a Closed Subscriber Group (CSG) Identifier (ID) and neighbor information of the second BS; and

transmitting, by the first BS, an X2 setup response message to the second BS, wherein the X2 setup response message comprises the CSG ID and neighbor information of the first BS.

3. An apparatus for a first Base Station (BS) in a mobile communication system, the apparatus comprising:

a communication unit configured to receive an X2 setup request message from a second BS, wherein the X2 setup request message comprises a Closed Subscriber Group (CSG) Identifier (ID) and neighbor information of the second BS, and configured to transmit an X2 setup response message to the second BS, wherein the X2 setup response message comprises the CSG ID and neighbor information of the first BS.
