"PUBLIC MOBILE ACCESS DATA NETWORK ON AN INTERNET, METHOD AND FIRST ROUTING NODE FOR USE IN A PUBLIC MOBILE ACCESS DATA NETWORK". A public mobile access data network provides mobile node data access to the Internet and data access to the Internet mobile even when a connection point from the mobile to the public mobile access data network changes. A public mobility management service is provided to locate mobile nodes so that the Internet is aware of the current point of connection of the mobile node. Advantageously, this public mobility management service is provided independently of mobility services offered by specific radio access technology networks. The public mobile access service is implemented using a domestic agent / foreign agent model where domestic and foreign agents transfer data packages through the public mobile access network through a data tunnel. In a preferred example embodiment, mobile Internet protocol (IP) is used at the network protocol layer to provide the public mobility service. Mobile IP packets are carried using multi-protocol label path switching (MPLS) and label switched paths (LSPS) that provide various benefits such as channeling flexibility, configurability and efficiency.
