A METHOD AND AN APPARATUS FOR NON-ACCESS STRATUM MESSAGE PROCESSING DURING HANDOVER IN EVOLVED NETWORK |
摘要 |
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. |
