 ====!"§==Systems= Project goals Goal 1: Service Extension: to provide existing and emerging IP-based applications and services for mobile users without direct access to the fixed networks. Goal 2: Ad hoc Integration: to propose an open architecture for the interaction of Radio Access Network (HotSpot, GPRS/ UMTS ) and Ad hoc networks. Goal 3: Mobility Support: to support mobility in heterogonous radio access networks. Goal 4: Billing & Charging: to design a Billing & Charging methods for IPonAir. Goal 5: Computer Simulation: to develop a framework for the performance evaluation (TCP/IP, Handover, Interworking and Interaction) by simulation tools. Goal 6: Trials: to test the developed functions (Service Extension, Mobility support) by practical means.
