Abstract
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.
Claims19
-30. (canceled)
A method comprising:
- preparing an internet key exchange security association message, using a processor;
- containing in the security association message an extension indicative of a mobile internet protocol binding related instruction to a home agent;
- and
- sending the security association message to a packet data network.
A method according to claim 3Error! Reference source not found, wherein the method further comprises:
- communicating by the mobile node through a first packet data network;
- changing to communicate by the mobile node through a second packet data network and
- responsively performing the preparing of the internet key exchange security association message.
A method according to claim 332, further comprising establishing a security association between a mobile node and an intervening network element.
An apparatus comprising a memory configured to store instructions and a processor configured to perform according to the instructions:
- prepare an internet key exchange security association message;
- contain in the security association message an extension indicative of a mobile internet protocol binding related instruction to a home agent;
- and
- send the security association message to a packet data network.
An apparatus according to claim 339, wherein the apparatus is a mobile node.
An apparatus comprising a memory configured to store instructions and a processor configured to perform according to the instructions:
- receive from a mobile internet protocol mobile node an internet key exchange security association message;
- determine in the security association message a mobile internet protocol binding related instruction to a home agent of the mobile node;
- store a mobile internet protocol message based on the determined mobile internet protocol related instruction;
- and
- send the mobile internet protocol message to the home agent of the mobile node.
A computer readable memory medium comprising computer executable program code for causing an apparatus when processing the program code to:
- prepare an internet key exchange security association message;
- contain in the security association message an extension indicative of a mobile internet protocol binding related instruction to a home agent;
- and
- send the security association message to a packet data network.
