Claim of US Patent No. 10,560,913

1. A method for acquisition of information of a control node, comprising:receiving, by a relay node (RN) that needs to acquire information of an MME to which one UE under the relay node accesses for judging a handover type and/or MME correct addressing but the relay node is not informed of the information of the MME to which the one UE under the relay node accesses, through wireless network, a message sent by a base station and acquiring, by the relay node, information of one control node to which the one UE under the relay node accesses, wherein the information of the one control node is carried in the message and the information of the one control node is the information of the MME to which the one UE under the relay node accesses; and
determining a handover type and/or addressing the one control node to which the one UE under the relay node accesses according to the information of the one control node to which the one UE under the relay node accesses;
wherein the receiving, by the relay node through wireless network, the message sent by the base station further comprising:
receiving, by the relay node, a predefined S1 or X2 message carrying the information of the one control node to which the one UE under the relay node accesses.
