Abstract:
1. A method for routing packets to a mobile node comprising the steps of: providing an address update, including a regional care-of-address associated with the mobile node, to a node communicating with the mobile node; sending packets, from the node communicating with the mobile node, to a node associated with the regional care-of-address; receiving packets at the node associated with the regional care-of-address; determining, at the node associated with the regional care-of-address, a current address of the mobile node; routing the received packets to a node associated with the current address of the mobile node; forwarding packets, from the node associated with the current address, to the mobile node; wherein the packets are sent between the node communicating with the mobile node and the mobile node in accordance with mobile Internet Protocol version 6 (MIPv6) protocol; sending a message, from the mobile node to the node associated with the mobile node's regional care-of-address, requesting that packets be routed to the mobile node's current address and at least another current address of the mobile node; routing a first group of packets, from the node associated with the mobile node's regional care-of-address, to a node associated with the mobile node's current address; and routing a second group of packets, from the node associated with the mobile node's regional care-of-address, to a node associated with the at least another one of the mobile node's current addresses.
