摘要

A first base station (1) is configured so as to transmit, to a second base station (2), first setting information that is necessary for establishing a data bearer and a data radio bearer in the second base station (2) for a C/U-plane split scenario (S105). Also, the first base station (1) is configured so as to continue to keep the first setting information in the first base station (1) (S109), even after the establishment of the data bearer and the data radio bearer in the second base station (2). Thus, for example, it is possible to contribute to the reduction of path-switching delays at the time when a UE moves between cells in a C/U-plane split scenario.
