Patent number: 7577119Abstract: A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2 registers the MAC address of the MN in a handoff request message (FHReq), and the FA2 feeds the FHReq onto a transfer network. Each of foreign agents (FAs) receives the FHReq, registers an IP address corresponding to the MAC address in the FHReq when the MAC address is registered in a binding list of the FAs themselves, and feeds the IP address onto the transfer network. The FA2 receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2 itself. The FA2 transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.Type: GrantFiled: March 4, 2005Date of Patent: August 18, 2009Assignees: KDDI Corporation, National Institute of Information and Communications Technology, Incorporated Administrative AgencyInventors: Hidetoshi Yokota, Takeshi Kubo, Akira Idoue, Masugi Inoue, Khaled Mahmud
