1. A method for transporting packets in a mobile Internet Protocol (IP) network, the method comprising:
- assigning a short mobile node identifier to a mobile node in response to a first message received from the mobile node;
transmitting the short mobile node identifier to the mobile node in a second message; and
receiving a packet from the mobile node, wherein the packet includes the short mobile node identifier in place of a home address, and further wherein the short mobile node identifier is used throughout an entire communication path between the mobile node and the correspondent node.

Abstract
The present invention concerns a method and system for optimizing transport efficiency between a Mobile Node and a Correspondent Node in a Mobile IP network. A short Mobile Node Identifier is assigned to the Mobile Node. A Mobile Node Identifier Destination Option header comprising the assigned Mobile Node Identifier is used instead of the prior art Home Address Destination Option header in subsequent packets between the Mobile Node and the Correspondent Node.
