Patent ID: 8400980

Claim:
A fast handover method comprising: allowing a mobile node (MN) to transmit a handover information message to a previous mobile access gateway (PMAG); allowing the PMAG to transmit a fast proxy binding update (FPBU) message to a local mobility anchor (LMA) that is separate from the PMAG on the basis of the handover information message received from the MN; allowing the LMA to transmit a handover initiation (HI) message including MN-ID and proxy-care-of address (CoA) of the PMAG to a new MAG (NMAG) without communication of information in the handover information message between the PMAG and the NMAG; transmitting a position update message to the NMAG if the MN is attached to a target BS that is connected to the NMAG; and allowing the NMAG to deliver a buffered packet to the MN.
