1. A terminal apparatus that performs communication using a communication path that is set between the terminal apparatus and a core network via a base station apparatus that is connected to the core network and a relay apparatus that relays communication with the base station apparatus, the terminal apparatus comprising:
one or more processors; and
one or more memories that store a computer readable instruction for causing, when executed by the one or more processors, the terminal apparatus to:
acquire information regarding one or more communication path candidates to which switching is to be performed from a first communication path that is being used, from the base station apparatus that functions as a serving base station in the first communication path, wherein the information regarding the one or more communication path candidates includes a list including the base station and the relay apparatus that form a communication path included in the one or more communication path candidates,
determine whether or not switching of the communication path from the first communication path is to be performed, and
perform switching from the first communication path to a second communication path included in the one or more communication path candidates, in response to the determination that switching of the communication path from the first communication path is to be performed after receiving the information regarding the one or more communication path candidates.
