Abstract
A radio communication system includes a user device, a first base station, a second base station, a third base station, a gateway device, and a switching center. A user-plane path is established between the user device and the gateway device via the third base station. When the user device is handed over from the first base station to the second base station, the first base station adds an identifier of the third base station to a handover request message and transmits the handover request message to the second base station. The second base station transmits, to the third base station, a base station switch notification message that indicates that a radio connection destination for the user device has been switched to the second base station.
