Abstract
This is a method and system to efficiently do handovers for mobile IP. The mobile node registers itself with several foreign agents using a new registration type. Only one of the foreign agents is selected to forward the data packets of a data message to the mobile node. The selection algorithm may be one based on randomness, dynamic learning, message traffic congestion, or statistical information collected at the mobile node.
Claims42
A method of transmitting data messages in a mobile communication network to a mobile node comprising:
- providing a plurality of foreign agents which are bound to the mobile node in a geographical area;
- selecting only one of the foreign agents to deliver a data message comprising data packets to the mobile node;
- and
- transmitting the message with the mobile communicating network using only the selected one foreign agent to the mobile node.
A system which transmits data messages in a mobile communication network using the internet protocol to a mobile node comprising:
- a plurality of foreign agents;
- means for assigning a home address to a data message comprising data packets in the network;
- means for assigning a care of address to the data message which is used to deliver the data message to the plurality of foreign agents;
- and
- means for selecting only one foreign agent from the plurality of foreign agents;
- and wherein
- the mobile communication network delivers the data message from the selected only one foreign agent to the mobile node.
