First Claim
Patent Images
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, andthe 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.

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.

15. A gateway for mobile access, comprising:
-
a foreign agent that receives user profile data from a home authentication, authorization and accounting (AAA) system of a client, when the client establishes a session with the gateway; a dynamic packet filter that performs multi-layer filtering based on the user profile data; an access point contained within or attached to a housing of the gateway, for communication between the gateway and the client; and a wireless modem contained within or attached to a housing of the gateway, wherein the gateway is mobile, and the modem permits wireless communication between the gateway and a wireless network. - View Dependent Claims (16, 17, 18, 19, 20)

21. A computer readable medium encoded with computer program code, wherein, when the code is executed by a processor, the processor performs a method for controlling mobile access, comprising the steps of:
-
filtering incoming packets based on a media access control address of each packet; obtaining user profile data of a mobile IP node from a home authentication, authorization and accounting (AAA) server of a mobile IP node, to determine whether the mobile IP node is registered to access a network by way of a gateway; performing multi-layer filtering based on the user profile data; transferring a session from a first network to a second network in which the mobile IP node is located without session interruption when the mobile node moves to the second network; and providing Internet access to the mobile IP node without passing Internet data requested by the mobile IP node through a network in which the home AAA server is located.
