The invention discloses a control method of base station interface establishment. UE (user equipment) discovers and reports a new cell to an eNB, the eNB acquires a TNL (transport network layer) address of HeNB by an MME (mobility management entity) and a HeNB GW (home eNodeB gateway), the eNB sends an X2 interface establishment request message to the HeNB, the HeNB judges the access mode of the HeNB is a mixed mode, an open mode or a close mode, if the access mode is a mixed mode or an open mode, the HeNB feeds back an X2 interface establishment response message to the eNB, wherein the X2 interface establishment response message comprises a C S G ID of the HeNB and access mode information; if the access mode is a close mode, the HeNB feeds back an X2 interface establishment failure information to the eNB. The invention discloses a communication system. By adopting the control method of base station interface establishment and the communication system provided by the invention, the X2 interface can be preferentially selected for switching the base station of the UE, thus the singling flow of the core network can be reduced.
