Abstract:
A mobile communication system includes a first radio control device that manages a first cell, a second radio control device that manages a second cell, and a third radio control device. The second cell is set as a handover destination cell of the first cell. The third radio control device manages the second cell as a redundant configuration of the second radio control device. The third radio control device notifies the first radio control device of the third radio control device managing the second cell as the redundant configuration of the second radio control device. The first radio control device sets so that the third radio control device manages the second cell as the redundant configuration of the second radio control device.
