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.

Claims

1. 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.

2. The system of claim 1, wherein signaling further comprises registration with a replica of the mobile node by the ghost-mobile node to communicate with the foreign agents, triggering tunneling and communication with a mechanism configured to maintain routing information to a mobile node.

3. The system of claim 1, wherein signaling further comprises at least one of a tunnel and a communication network to allocate resources between the mobile node and foreign agent, the signaling being triggered at a threshold distance to one of the foreign agents reported by one of the mobile nodes, the threshold distance reported to one of the foreign agents at least one of a projected trajectory and a speed.

4. The system of claim 1, wherein the at least one ghost-mobile node is a proxy element for the at least one foreign agent and the at least one mobile node, the at least one ghost-mobile node triggering registration based on a distance to a foreign agent by relaying security and shared secrets from a mobile node, and at least one advertisement message from a foreign agent in a vicinity of the ghost-mobile node.

5. The system of claim 1, wherein allocation of resources on behalf of the mobile node is triggered based at least in part on location information, the location information determined by at least one of:

a global positioning system (GPS) receiver, a triangulation process, and indirect measurements of location.

6. The system of claim 1, wherein the at least one ghost-foreign agent populates mobile IP Advertisement messages with at least one care-of-address of neighboring foreign agents in order to extend the range of neighboring foreign agents.

7. 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.

8. 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;

registering, in the mobile node, with the foreign agent through the ghost foreign agent; and

broadcasting advertisement messages from the plurality of ghost foreign agents to the mobile node to extend a reach of the foreign agent, wherein a distance from the mobile node to one of the ghost foreign agents is less than the distance from the mobile node to the foreign agent.
