Abstract
A data communication method and apparatus for a mobile network. A destination foreign agent (FA) recognizes a MAC address of an MN. The FAregisters the MAC address of the MN in a handoff request message (FHReq), and the FAfeeds 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 FAreceives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FAitself. The FAtransfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.
