Abstract: The present invention relates to methods for providing access independent global roaming between heterogeneous networks. The invention solves this problem and provides policy enforcement and service transparency when terminals roam between different heterogeneous networks. By providing a policy enforcement point associated with the terminal, and by concerning the transport mechanism between terminals and servers as a packet pipe, adding no extra value except transport and Quality of Service classification thereof. The payment for access and services can be separated and access may be paid in real-time by an anonymous payment method. In accordance with the invention, the terminal becomes more like a personal profile manager, managing rights to services and access. The ability to purchase access opens the possibility for the terminal to act as an e-commerce platform, and the subscriber can access any network any time since access is paid for in real time.

Abstract: A packet pipe architecture is disclosed for an access network (e.g., provides access to an IP, ATM or similar packet-based network in order to convey packet data traffic), whereby the network interfaces with the packet pipe are standardized so that any packet pipe that satisfies the interface requirements can be utilized in the same access network. Also, the packet pipe uses a packet-based protocol stack with Quality of Service provisions for service delivery instead of the conventional best effort service delivery functions used. Consequently, the packet pipe and access network are capable of providing all of the numerous services available with an IP, ATM or similar packet-based network layered architecture.
