摘要： PROBLEM TO BE SOLVED: To execute sequence control of downlink data in a wireless access device of a handover destination when Inter-RAT handover is executed. SOLUTION: A mobile communication method has: a step in which, when a gateway device S-GW is switched from a first state of transmitting downlink data to a first wireless access device into a second state of transmitting the downlink data to a second wireless access device, the first wireless access device imparts specific information to the downlink data received from the gateway device S-GW so as to transfer the data to the second wireless access device; and a step in which the second wireless access device transmits the downlink data to be transferred, which is transferred from the first wireless access device and imparted with the specific information, to a mobile station UE prior to transmission of the new downlink data transmitted from the gateway device S-GW.

摘要： PROBLEM TO BE SOLVED: To allow sequence control of downlink data in a radio access device of a handover destination, when Inter-RAT handover is to be carried out.
SOLUTION: This mobile communication method includes a step in which when a gateway device S-GW is switched, from a first state of sending the downlink data to a first radio access device to a second state of sending the downlink data to a second radio access device, and the first radio access device provides specific information to the downlink data received from the gateway device S-GW to transfer it to the second radio access device; and a step in which the second radio access device sends transfer downlink data provided with the specific information transferred from the first radio access device to a mobile station UE, prior to new downlink data being sent from the gateway device S-GW.
