Abstract
A hand-off notifying and controlling system of a mobile node is disclosed including a mobile node (MN) that transmits a registration request message. An old foreign agent (FA) provides a mobile IP service to the MN, before the hand-off takes place. A new FA provides a mobile IP service to the MN, after the hand-off takes place. A home agent (HA) generates and transmits a registration release message to the old FA, upon receipt of the registration request message from the MN via the new FA. When the MN is handed off, since the HA deletes the previous registration of the MN, registered in the old FA, the waste of memory resources and registration lock dead can be simply and effectively reduce or solved.
