インターネットプロトコルレイヤーにおける低オーバーヘッド移動度管理プロトコルのための方法およびシステム

Japanese Patent JP2004530327

A

The present invention provides a communication terminal configured as a Mobile Node, MN, for use in network system that supports mobile Internet communication and has a plurality of Routers each having a unique communication address via which MNs communicate with the Internet via different Routers at different locations where each Router has an associated Mobile Node Location List identifying each MN for which the Router is the home Router and the communication address of a Router corresponding to a current location of each such MN, the communication terminal characterized by: means for storing a unique host name and a home network identifier, HNI, that reflects an association with a home Router; and means for communicating to the terminal's home Router, when said terminal is moved from an old location where the terminal communicates with the Internet via one Router to a current location where the terminal communicates with the Internet via a different Router, the communication address of the different Router as the communication address corresponding to the terminal's current location whereby a data communication from a corresponding node, CN, to the terminal is communicated to the terminal using the terminal's HNI and unique host name by accessing the Mobile Node Location List of the terminal's home Router to determine the communication address corresponding to the terminal's current location and directing the data communication to that determined communication address.
