Document Type and Number:
WIPO Patent Application WO/2004/109993
Kind Code:
A1
Abstract:
An IP network system includes an IP network divided into a plurality of segments, an MN (mobile node) whose C/O address is set for each segment where it is located, and a CN (corresponding node) which is a communication partner of the MN. The system further includes at least a C/O address management unit for managing an old C/O address set in a segment before movement and a new C/O address set in a segment after movement, an IP packet reception unit for receiving an IP packet destined to the old address transmitted from the CN after the MN has moved to another segment position, and an IP packet transfer unit for transferring the IP packet destined to the old C/O address and received by the IP packet reception unit to a new C/O address managed by the C/O address management unit.
