Abstract

A method and device for establishing an X2 link are disclosed in the invention. The method includes that: a first base station sends an X2 link establishment request message to a second base station, for requesting to establish an X2 link between the first base station and the second base station(101); wherein the X2 link establishment request message includes an identifier of a first MME and an identifier of a first SGW corresponding to the first base station; the first base station receives an X2 link establishment response message returned based on the X2 link establishment request message by the second base station, so as to establish the X2 link(102); the X2 link establishment response message includes an identifier of a second MME and an identifier of a second SGW corresponding to the second base station. In the embodiments of the invention, the first base station and the second base station can obtain the MME and the SGW corresponding to the opposite end respectively in the course of the X2 link establishment, therefore, when a UE hands off between the first base station and the second base station, the first station or the second station can make an accurate handoff decision.
