A tunneling optimization is described in which packets are forwarded from a home agent to a mobile device by co-locating a foreign agent corresponding to a mobile device at the mobile device. When a mobile device acquires a new foreign agent, the mobile device notifies the home agent as to the corresponding foreign agent address. A packet received at the home agent having the mobile device as a packet header destination address is parsed and the foreign agent address is substituted for the mobile device address, and the packet is forwarded to the foreign agent. The foreign agent, upon receiving the packet, removes the foreign agent address and replaces the mobile device address as the packet header destination address. The packet is then forwarded to the mobile device.

1. A method of providing packet delivery to a wireless device having a foreign agent over a wired packet-based network, said method comprising the steps of:providing a home agent corresponding to said wireless device with a foreign agent address associated with said wireless device, said wireless device also having a home address; receiving, at said home agent, a packet having said home address as a packet header destination address; substituting said foreign agent address for said home address as said packet header destination address for said packet; forwarding said packet from said home agent to said packet header destination address; and setting a header field included within said packet to identify said packet as a packet on which tunneling optimization has been performed, said packet header being substantially the same size after substitution.
