Method, system and equipment for indicating transmission in start stage and selecting gateway node

The embodiment of the invention discloses a method, a system and equipment for indicating transmission in a start stage and selecting a gateway node, relates to the technical scheme of wireless communication, and is used for solving the problem that how mobile management equipment (MME) selects the gateway node for a relay node (RN). In the Attach process of the RN and the MME, the MME determines whether information used for indicating the current start stage of the RN is received, and if so, the current start stage of the RN is determined according to the information, otherwise, the current start stage of the RN is determined according to a preset RN start stage decision rule; and the gateway node is selected for the RN according to the current start stage of the RN. By the invention, the MME can select the gateway node for the RN according to the start stage of the RN.
