Abstract: A terminal network apparatus performs wireless communication with a user terminal apparatus. The terminal network apparatus receives a registration request which is transmitted from the user terminal apparatus, and assigns a node name to the user terminal apparatus. The terminal network apparatus receives a reregistration request from a user terminal apparatus which has moved from a wireless service area of another terminal network apparatus, and assigns a new node name to the user terminal apparatus. The terminal network apparatus transmits a notification that includes an old node name and the new node name to the terminal network apparatus that had assigned the old node name. When the terminal network apparatus receives the notification, the terminal network apparatus generates an entry, in which the old node name and the new node name are correlated, in a node name pair table.
