Abstract
A method for imposing a communication policy for a mobile node. During Mobile-IP (MIP) registration for the mobile node, when a MIP home agent sends an access request to an authentication, authorization, and accounting (AAA) server, the AAA server will select a pool of IP addresses corresponding with a communication policy for the mobile node and will direct the home agent to assign an IP address selected from that pool. Thereafter, when the home agent receives a communication to or from the IP address, the home agent may then determine the applicable communication policy by determining the pool from which the IP address was selected, and the home agent may apply that communication policy.
