A method for selecting a donor cell, carried out at a relay node, the method comprising: establishing (501, 901) a radio resource control, RRC, connection between the relay node and a donor cell; acquiring (507, 907), from an operation and maintenance system, donor cell configuration information for the relay node, wherein the donor cell configuration information indicates donor cells for the relay node; determining (508, 908) whether a cell to which the relay node currently connects is comprised in the donor cells indicated in the donor cell configuration information, based on the donor cell configuration information; if the relay node determines that the cell to which the relay node currently connects is comprised in the donor cells indicated in the donor cell configuration information, continuing working in the cell to which the relay node currently connects; if the relay node determines that the cell to which the relay node currently connects is not comprised in the donor cells indicated in the donor cell configuration information, performing a procedure, characterized in that, the procedure is a cell reselection procedure, which comprises: releasing (508, 909, 910) the RRC connection; reselecting (508, 910) one of the donor cells indicated in the donor cell configuration information according to the donor cell configuration information; requesting (509, 911) activation or establishment of an evolved packet system EPS bearer; accessing (509, 911) the one of the donor cells. establishing (501, 901) a radio resource control, RRC, connection between the relay node and a donor cell; acquiring (507, 907), from an operation and maintenance system, donor cell configuration information for the relay node, wherein the donor cell configuration information indicates donor cells for the relay node; determining (508, 908) whether a cell to which the relay node currently connects is comprised in the donor cells indicated in the donor cell configuration information, based on the donor cell configuration information; if the relay node determines that the cell to which the relay node currently connects is comprised in the donor cells indicated in the donor cell configuration information, continuing working in the cell to which the relay node currently connects; if the relay node determines that the cell to which the relay node currently connects is not comprised in the donor cells indicated in the donor cell configuration information, performing a procedure, characterized in that, the procedure is a cell reselection procedure, which comprises: releasing (508, 909, 910) the RRC connection; reselecting (508, 910) one of the donor cells indicated in the donor cell configuration information according to the donor cell configuration information; requesting (509, 911) activation or establishment of an evolved packet system EPS bearer; accessing (509, 911) the one of the donor cells. releasing (508, 909, 910) the RRC connection; reselecting (508, 910) one of the donor cells indicated in the donor cell configuration information according to the donor cell configuration information; requesting (509, 911) activation or establishment of an evolved packet system EPS bearer; accessing (509, 911) the one of the donor cells.
