  • Patent number: 9215624
    Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.

  • Patent number: 8363619
    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 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.
