A method for obtaining information of a neighbor cell, comprising: a donor base station sending to a relay node an X2 interface signaling carrying indication information representing whether a cell is administered by a relay node which is administered by the donor base station or information representing whether the donor base station already sets up an X2 interface with another base station to which the cell belongs, and wherein, the relay node receiving the X2 interface signaling is a relay node administered by the donor base station or a relay node administered by said another base station, characterized in that: when the X2 interface signaling carries cell attribute information which comprises the indication information representing whether the cell is administered by a relay node which is administered by the donor base station, if the relay node receiving the X2 interface signalling is a relay node administered by the donor base station, then the step of the donor base station sending to the relay node the X2 interface signaling comprises: the donor base station, after receiving an X2 setup request sent by the relay node administered by the donor base station, replying an X2 setup response to the relay node administered by the donor base station, wherein the X2 setup response carries configuration information of a cell administered by another relay node which is administered by the donor base station and indication information indicating that the cell administered by the another relay node is administered by the another relay node which is administered by the donor base station; and the relay node administered by the donor base station, after receiving the cell attribute information, updating corresponding cell attribute. a donor base station sending to a relay node an X2 interface signaling carrying indication information representing whether a cell is administered by a relay node which is administered by the donor base station or information representing whether the donor base station already sets up an X2 interface with another base station to which the cell belongs, and wherein, the relay node receiving the X2 interface signaling is a relay node administered by the donor base station or a relay node administered by said another base station, characterized in that: when the X2 interface signaling carries cell attribute information which comprises the indication information representing whether the cell is administered by a relay node which is administered by the donor base station, if the relay node receiving the X2 interface signalling is a relay node administered by the donor base station, then the step of the donor base station sending to the relay node the X2 interface signaling comprises: the donor base station, after receiving an X2 setup request sent by the relay node administered by the donor base station, replying an X2 setup response to the relay node administered by the donor base station, wherein the X2 setup response carries configuration information of a cell administered by another relay node which is administered by the donor base station and indication information indicating that the cell administered by the another relay node is administered by the another relay node which is administered by the donor base station; and the relay node administered by the donor base station, after receiving the cell attribute information, updating corresponding cell attribute. when the X2 interface signaling carries cell attribute information which comprises the indication information representing whether the cell is administered by a relay node which is administered by the donor base station, if the relay node receiving the X2 interface signalling is a relay node administered by the donor base station, then the step of the donor base station sending to the relay node the X2 interface signaling comprises: the donor base station, after receiving an X2 setup request sent by the relay node administered by the donor base station, replying an X2 setup response to the relay node administered by the donor base station, wherein the X2 setup response carries configuration information of a cell administered by another relay node which is administered by the donor base station and indication information indicating that the cell administered by the another relay node is administered by the another relay node which is administered by the donor base station; and the relay node administered by the donor base station, after receiving the cell attribute information, updating corresponding cell attribute. the donor base station, after receiving an X2 setup request sent by the relay node administered by the donor base station, replying an X2 setup response to the relay node administered by the donor base station, wherein the X2 setup response carries configuration information of a cell administered by another relay node which is administered by the donor base station and indication information indicating that the cell administered by the another relay node is administered by the another relay node which is administered by the donor base station; and the relay node administered by the donor base station, after receiving the cell attribute information, updating corresponding cell attribute.
