Abstract
A system for communication between a mobile node and a communications network is provided for use with a communications network having one or more communications network nodes that define a foreign agents and that communicate with the mobile node in a predefined region. The system includes a ghost-foreign agent that advertises a foreign agent so that the mobile node is aware of the foreign agent when the mobile node is located outside the predefined region. The system further includes a ghost-mobile node that signals the foreign agent in response to the foreign agent advertising and based upon a predicted future state of the mobile node.

29. A system for communicating between a mobile node and a communication network;
- the network having at least one communications network node that is interconnected using a proxy mobile internet protocol (IP), comprising;
at least one mobile node; at least one home agent; at least one foreign agent; a ghost-foreign agent that advertises messages to one of the mobile nodes indicating presence of the ghost-foreign agent on behalf of one of the foreign agents when the mobile node is located in a geographical area where the foreign agent is not physically present; and a ghost-mobile node that creates replica IP messages on behalf of a mobile node, the ghost-mobile node handling signaling required to allocate resources and initiate mobility on behalf of the mobile node, the ghost-mobile node triggering signals based on a predicted physical location of such mobile node or distance with relation to the at least one foreign agent.
- the network having at least one communications network node that is interconnected using a proxy mobile internet protocol (IP), comprising;

35. A method, in a mobile node, for speeding handover, comprising the steps of:
-
updating, in a mobile node, a location in a ghost mobile node; determining a distance, in the ghost mobile node in communication with the mobile node, to a closest foreign agent with which the mobile node can complete a handover; submitting on behalf of the mobile node, from the ghost mobile node, a registration to the foreign agent to which the mobile node is going to complete the handover; and upon completing the handover, updating a registration in the mobile node.

36. A method, comprising the steps of:
-
creating, in a network, a plurality of ghost foreign agents corresponding to a foreign agent, the ghost foreign agents configured to replicate mobile advertisements of the foreign agent, the mobile advertisements including at least one of;
an IP address of the foreign agent, a care-of-address of the foreign agent, and at least one mobile IP registration, the ghost foreign agents created at a distance surrounding the foreign agent;detecting, in a mobile node, the foreign agent in the network; receiving, in the mobile node, an advertisement message corresponding to the foreign agent from one of the ghost foreign agents; and registering, in the mobile node, with the foreign agent through the ghost foreign agent. - View Dependent Claims (37)

38. A method of tracking a trajectory of a mobile node, comprising the steps of:
-
generating, in a foreign agent, a predicted location of the mobile node; notifying a neighboring foreign agent of the predicted location; generating, in the neighboring foreign agent, an advertisement message, the advertisement message transmitted to the mobile node from the neighboring foreign agent; and initiating, in the mobile node, registration with the neighboring foreign agent using a mobile IP handover mechanism.
