Abstract
This paper describes the system design and implementation of a demonstrator prototype, running at University of Bre-men, which implements Mobile IP handoffs between GPRS and WLAN systems. Mobile IP requires public IP ad-dresses but there is no support of such IP addresses by most mobile operators. To solve the problem of NAT (Net-work Address Translation) and firewalls resulting from this, several concepts are available. This paper presents a practical implementation of one such concept where Mo-bile IP handoffs are realised using tunneling functions and an additional Mobile IP Foreign Agent to provide GPRS network access. Furthermore, this paper presents meas-urement results of the test bed and shows the quality of the Mobile IP handoffs.
