Method for extending mobile IP and AAA to enable integrated support for local access and roaming access connectivity

摘要

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.
