発明の名称 (英語) NETWORK DEVICE, NETWORK SYSTEM, AND OPERATION METHOD THEREFOR
発明の概要(英語) [Problem] To enable recognition of a user's destination even if the destination of a moving user is uncertain. [Solution] A terminal network device (10) performs wireless communication with a user terminal device (50). The terminal network device (10) receives a registration request transmitted from a user terminal device (50) and allocates a node name to the user terminal device (50). The terminal network device (10) receives a reregistration request from a user terminal device (50) that has moved from the wireless service area of another terminal network device (10), and allocates a new node name to the user terminal device (50). The terminal network device (10) transmits, to the terminal network device (10) that allocated the old node name, a notification including the old node name and the new node name. After receiving the notification, the terminal network device (10) creates an entry in a node name pair table in which the old node name and new node name are associated.
