Abstract: A network apparatus includes: a network selection part which selects, between a first network and a second network that accommodates a terminal(s) that belongs to a predetermined terminal type, a network to which a terminal is to be connected, based on the terminal type; and a connection request processing part which transmits, when the second network is in a state where the second network cannot accommodate the terminal(s) that belongs to the predetermined terminal type, a connection rejection request in which a back-off timer value indicating a time period during which transmission of a next network connection request is inhibited, is set, to a network connection request from a terminal concerned.

Abstract: In order to suppress a terminal from being connected to an inappropriate system when failures occur in a base station, this relay device comprises: a transmission means that, when failures occur in a base station, transmits a connection request including authentication information to a terminal connected to a network via the base station; a reception means that receives, from the terminal that has received the connection request, a notification indicating that connection is permitted; and a relay means that, upon being notified by the reception means that the notification has been received, relays communication between the terminal and the network.
