Abstract: A base-station apparatus includes: a communicator that performs wireless communication; and a controller. During communication with at least a first terminal apparatus, when a communication volume used for communication that is newly stated with a second terminal apparatus becomes smaller than or equal to an un-used communication volume, the controller transmits, to a target terminal apparatus that is one of the first and second terminal apparatuses, a communication instruction for communication with a second base-station apparatus having a coverage range in which the target terminal apparatus is located, and when a communication volume used for communication with the target terminal apparatus exceeds the un-used communication volume, the controller transmits a callback instruction for callback from the second base-station apparatus to the base-station apparatus to the target terminal apparatus or the second base-station apparatus.

Abstract: A communication apparatus includes a first communication unit configured to perform first communication using a first communication method, a second communication unit configured to perform second communication using a second communication method, and a controller. The controller performs the second communication via the second communication unit with a terminal apparatus supporting both of the first communication method and the second communication method and not performing communication using the first communication method, to acquire connection configuration information in the first communication method. The controller performs the first communication with a device other than the terminal apparatus via the first communication unit, using a configuration according to the connection configuration information.
