| 1. A gateway for mobile access, comprising;
a foreign agent that receives user profile data and session state data from a home authentication, authorization and accounting
(AAA) system of a mobile node;
at least one dynamic packet filter that performs multi-layer filtering based on the user profile data;
wherein the foreign agent transfers a session from a first network to a second network without session interruption, using
the session state data, when the mobile node moves from the first network to the second network, and
the foreign agent uses the dynamic packet filter to permit Internet access by the mobile node without passing Internet data
requested by the mobile node through a network in which the home AAA system is located.
