ABSTRACT:
A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2registers the MAC address of the MN in a handoff request message (FHReq), and the FA2feeds 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 FA2receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2itself. The FA2transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.
