ABSTRACT:
In a handover method, a mobile node receives a Layer2trigger message; requests information on Layer3of a new access router (NAR) from a previous access router (PAR) by using information included in the Layer2trigger message and information on an IP address of the NAR and a new Care of Address (NCoA) to be used when moving to the NAR; and performs registration with a Home Agent (HA) of the mobile node and sending binding update to an associated correspondence node by using the NCoA when a Layer2handover is occurred. With this configuration, the present invention provides a handover method automatically creating an address using a MAC (Medical access control) address in the mobile IPv6 (Internet Protocol version 6).
