Abstract
A method and apparatus for use in a Proxy Mobile IP communications network. An anchor point function serves at least one mobile host. The anchor point function generates an IP address for use by the mobile host, the address being generated using cryptographic materials owned by the anchor point function. The anchor point function can then perform signalling on behalf of the mobile host, using the IP address generated for the mobile host and at least part of the cryptographic materials used to generate the IP address.
Claims14
A method for use in a Proxy Mobile Internet protocol (IP) communications network, the method comprising:
- at an anchor point function serving at least one mobile host through a remote access router, generating an IP address for use by the mobile host, the IP address being generated at least in part using cryptographic materials solely owned by the anchor point, wherein the cryptographic materials comprise a public/private key pair owned by the anchor point function;
- and
- performing, at the anchor point function, signaling on behalf of the mobile host, using the IP address generated for the mobile host and at least part of the cryptographic materials used to generate the IP address.
An anchor point function for use in a proxy mobile communications network, the anchor point function serving at least one mobile host through a remote access router, comprising:
- a receiver for communicating with the at least one mobile host served by the anchor point function through the remote access router;
- a processor for generating an Internet protocol (IP) address for use by the at least one mobile host, the IP address being generated at least in part using cryptographic materials solely owned by the anchor point function, wherein the cryptographic materials comprise a public/private key pair owned by the anchor point function;
- and
- a transmitter for sending signaling on behalf of the mobile host, the signaling using the IP address generated for the mobile host and at least part of the cryptographic materials used to generate the IP address.
An access router for use in a Proxy Mobile Internet protocol (IP) communications network, the access router comprising:
- a receiver for receiving from an anchor point function remote from the access router signaling relating to a mobile host served by the anchor point function;
- and
- a transmitter for forwarding the signaling to a correspondent node, the signaling comprising packets defining an IP source address as an IP address generated by the anchor point for use by the mobile host, the IP address having been generated at least in part using cryptographic materials solely owned by the anchor point, wherein the cryptographic materials comprise a public/private key pair owned by the anchor point function.
