Patent number: 8363619Abstract: 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 that carries original S1 signaling connection parameter information to a target eNodeB to initiate a process that a user equipment (UE) is handed over to the target eNodeB. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a HANDOVER COMPLETE message that carries the original S1 signaling connection parameter and the new S1 signaling connection parameter of the new eNodeB to an evolved packet core (EPC). The EPC receives the HANDOVER COMPLETE message that carries the new S1 signaling connection parameter and the original S1 signaling connection parameter. 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.Type: GrantFiled: May 15, 2009Date of Patent: January 29, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Hongzhuo Zhang, Yong Qiu
