<p>A mobile communication method comprises: a step in which a NAS function transmits a NAS-PDU to an S1-AP function; a step in which after the S1-AP function has received, from a handover source radio base station (eNB), an S1-AP response message notifying that the transfer of the NAS-PDU to a mobile station (UE) through a radio interface has been failed, when receiving, from a handover target radio base station (eNB), a notification indicating that the handover of the mobile station (UE) has been completed, the S1-AP function transmits a retransmission request of the NAS-PDU to an NAS protocol function; and a step in which, in response to the retransmission request, the NAS function retransmits the NAS-PDU to an S1-AP protocol function.</p> |
