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.
Claims24
A method for operating a base station (BS) in a mobile communication system, the method comprising:
- transmitting a setup request message to another BS, wherein the setup request message includes a closed subscriber group (CSG) identifier (ID) and neighbor information of the BS;
- receiving a setup response message from the another BS, wherein the setup response message includes a CSG ID and neighbor information of the another BS;
- and
- transmitting a handover request message to the another BS, wherein the handover request message includes a group membership state of a user equipment (UE).
