1. A mobility access gateway, the gateway comprising:
- a foreign agent for receiving a user profile data and a session state data associated with a session of a mobile node; and
a dynamic packet filter for performing multi-layer filtering based on the user profile data, whereinthe foreign agent is configured to transfer, using the session state data, the session from a first network to a second network without interrupting the session when the mobile node moves from the first network to the second network.

Abstract
A gateway for mobile access includes 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, and a dynamic packet filter that performs multi-layer filtering based on the user profile data. 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. The packet filter permits Internet access by the mobile node without passing Internet data requested by the mobile node through the first network.

11. A method for providing network access via a mobility access gateway, the method comprising:
-
receiving, at the mobility access gateway, a user profile data and a session state data associated with a session of a mobile node; performing multi-layer filtering based on the user profile data; using the session state data to transfer the session of the mobile node from a first network to a second network without interrupting the session when the mobile node moves from the first network to the second network. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A mobility access gateway, the gateway comprising:
-
means for receiving a user profile data and a session state data associated with a session of a mobile node proximate to the gateway; means for determining, based on the user profile data, a set of one or more user-specific firewall policies associated with the mobile node; a firewall configured to implement and apply the set of one or more user-specific firewall policies associated with the mobile node; and means transferring the session of the mobile node from a first network to a second network, based on the session state data, without interrupting the session when the mobile node moves from the first network to the second network. - View Dependent Claims (19, 20)
