At a mobile internet protocol (MIP) enabled mobile node (MN), an internet key exchange (IKE) security association (SA) message is prepared and an extension is contained in the SA message indicative of an MIP binding related instruction to a home agent (HA). The SA message is then sent to a packet data network. At a network element, the SA message and an IKE SA message are received from the mobile node. The network element determines in the SA message an MIP binding related instruction to the HA and stores an MIP message based on the determined MIP related instruction. The network element also sends the MIP message to the HA of the MN.
