This invention reduces the signaling overhead when starting a bearer split in inter-eNB carrier aggregation. This mobile communication method has the following steps: a step in which, if, with one bearer (bearer #1) set between one wireless base station (eNB #1) and a mobile station (UE), a decision to set another bearer (bearer #2) between said mobile station (UE) and another wireless base station (eNB #2) is made, a "Config copy indication" message that instructs the mobile station (UE) to copy an identifier for the other wireless base station (eNB #2) and the configuration of the one bearer (bearer #1) is transmitted to the mobile station (UE); and a step in which, in accordance with the identifier for the other wireless base station (eNB #2) and the "Config copy indication" message, the mobile station (UE) sets the other bearer (bearer #2) between said mobile station (UE) and the other wireless base station (eNB #2) with the same configuration as the one bearer (bearer #1). |
