MOBILITY ACCESS GATEWAY
First Claim
1. An apparatus for use on a mass transit vehicle, comprising:
- a GPS signal receiver for receiving GPS signals and processing the received GPS signals to generate GPS location data approximating a location of the mass transit vehicle;
a mobile hotspot module for providing a wireless access point for at least one user terminal of at least one passenger of the mass transit vehicle, the mobile hotspot module for propagating user data associated with the at least one user terminal; and
an Internet connection module for propagating the GPS location data from the GPS signal receiver and the user data from the mobile hotspot module toward the Internet.

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. The mobility access gateway may be used in combination with a GPS signal receiver to provide Internet access to passengers of a mass transit vehicle and to propagate GPS location data to the Internet for tracking the mass transit vehicle.
