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.
従来技術、競合技術の概要(英語) BACKGROUND ART
Currently, many of the traffic flowing over the Internet, such as web traffic or P2P traffic is traffic associated with the content distribution. On the other hand, the basic communication model is the heart of the Internet, 'and where' location-oriented importance to communicate with the communication based on the model being designed. When viewed from the viewpoint of the content distribution, the user interested in the content itself, or from where the content is obtained that is not of interest. That is, the user expects to receive the content by the communication model .
To this, in the application layer supports communication service have been various efforts have been made. However, such a communication service that supports information transfer-based (network) is still based on such architectures location-oriented, resulting in a deviation of the hierarchical. In recent years, to solve the problem resulting from this difference as a method, data to be transmitted around the network of content oriented network has been actively studied.
May include one or more content oriented network, or known ICN(Information Centric Network) CCN(Content Centric Network) (for example see Patent Document 1). At the CCN for example, the user, including the name of the content is sent to the CCN interest. CCN is, content interest routing based on the name, the requested content from a network node is found, the network node to transfer the content from the user.
In the CCN, CCN router, the user interest and transmitted by the relay transfer content to the user. In this case, the CCN router to cache the content. CCN router, the same content from other users when a request for, and acquires the content from the cache is transferred to the user. In the vicinity of the user can acquire the content from the CCN router, the amount of network traffic can be reduced.
Associated with the CCN, the non-patent document 1, content delivery utilizing the transportation has been described. In non-patent document 1, the user terminal and the wireless router is connected via a communication line provided in the train, train station and the router providing a device for wireless communication. Train operation according to the schedule giving the content distributed to each station, when the train arrives at the station of the station in the train from the router to transfer the content. The user of the train, receives the content from the router in the train.
