Abstract
A mobile communication method according to the present invention includes: the steps of: (A) transferring, from a first radio base station (S-eNB) to an upper level node (S-GW), consecutive uplink data received from a mobile station (UE) with their sequence numbers being consecutive, by use of a resource allocated by the upper level node (S-GW), when the first radio base station (S-eNB) determines that the mobile station (UE) is to perform a handover; (B) transmitting, from the first radio base station (S-eNB) to the upper level node (S-GW) transfer completion notification data after the transfer of the consecutive uplink data to the upper level node (S-GW) is completed; and (C) releasing, at the upper level node (S-GW), the resource when receiving the transfer completion notification data.
