1. A base station device comprising:
processor circuitry that executes a process including
judging whether each of a plurality of nodes that forms a relay network by establishing a wireless connection with each other and that is connected to the base station device is allowed to be connected to another base station device, and
generating, when it is judged that a first node is allowed to be connected to the another base station device, connection information that includes information related to the another base station device and standby time indicating a time period before the first node connects to the another base station device; and
a transmitter that transmits, via the first node, the connection information to a second node that is connected to a lower level of the first node in the relay network, and a terminal device that performs wireless communication with the first node or the second node, the transmitter changing connection destination of the second node and the terminal device to the another base station respectively after elapse of the standby time included in the connection information.
