The purpose of the invention is to realize an optimum architecture from the viewpoint of connectivity and mobility and the viewpoint of increasing system capacity and dispersing load, while minimizing the impact on the core network. In this mobile communication method, when a wireless base station (eNB#1) senses that a cell (#10) is in the vicinity of the mobile station (UE) when communication by the mobile station (UE) via an EPS bearer comprising a U-plane bearer between the mobile station (UE) in an RRC connected state and the wireless base station (eNB#1) and an S1-U bearer between the wireless base station (eNB#1) and the gateway device (S-GW) is being performed in a cell (#1) under the control of the wireless base station (eNB#1), an "RRC Connection Reconfiguration" including information associating identification information for the EPS bearer and the identification information for the cell (#10) is transmitted to the mobile station (UE). |
