Mobile communication services are getting more and more important and, in particular, multimedia services have attracted the interest of the users. Mobile TV is one of the most demanded candidates. Powerful and efficient communication systems are needed, which provide high capacities, especially at the downlink. Furthermore, interactivity is essential for supporting the user needs and to extend the service offering. As one possible solution to meet the mentioned requirements, the authors consider the combination of the cellular network UMTS and the mobile broadcast network DVB-H, which form a hybrid network. They investigate the performance of hybrid networks and develop a system model, which describes the hybrid network and the load switching between both networks.
