METHOD AND SYSTEM FOR LOW-OVERHEAD MOBILITY MANAGEMENT PROTOCOL IN INTERNET PROTOCOL LAYER

摘要

PROBLEM TO BE SOLVED: To provide a network system for mobile Internet communication support with improved network address translation.

SOLUTION: Each router having a unique communication signal address has an associated mobile node (MN) location list identifying each MN for which the router is a home router and the communication address of a router corresponding to a current location of each such MN. Each MN is movable from an old location where the MN communicates with the Internet via one router to a current location where the MN communicates with the Internet via a different router. Communication at the current location via the different router is established by communicating to the MN's home router the communication address of the different router as the communication address corresponding to the MN's current location. Accordingly, a data communication signal from a calling node to a selected MN is communicated by accessing the mobile node location list of the selected MN's home router to determine the communication address corresponding to the selected MN's current location and directing the data communication signal to the determined communication signal address.
