Abstract: A method, apparatus and system for establishing S1 signaling connections in an evolved network are disclosed. A source evolved NodeB (eNodeB) sends a handover request message to a target eNodeB to initiate a handover procedure during that a user equipment (UE) is handed over from the source eNodeB to the target eNodeB. The handover request message includes information about an original S1 signaling connection parameter. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a handover complete message to an evolved packet core (EPC). The handover complete messages carries the original S1 signaling connection parameter received from the source eNodeB and the allocated new S1 signaling connection parameter about the target eNodeB. With the present disclosure, the inability of the target eNodeB to establish an S1 signaling connection with the EPC in the related art is effectively solved.
