Abstract

This document describes a way to extend Mobile IP Authentication Authorization and Accounting (AAA) signaling to enable a node to request from a network operator combinations of home and local service capabilities (when roaming) in an efficient and scalable manner. It also enables the home and foreign service providers to constrain and account for actual services provided based on a combination of the foreign and home operator policy.

Claims

1. A communication node, comprising:

circuitry configured to receive a remote access message, relay the remote access message to a home agent, generate an authentication an authorization request message based on the remote access message, send the authentication and authorization request message to a proxy server, and establish two concurrent access services for a mobile node in response to a return message from the proxy server.

2. The communication node as in claim 1 wherein the remote access message comprises two profile selectors and a network access identifier.

3. The communication node as in claim 2 wherein the network access identifier comprises a real part for identifying a home service profile server and at a username part for identifying a service profile.
