Mobile communication services are getting more and more important and, in particular, multimedia services have#R##N#attracted the interest of the users. Mobile TV is one of the most demanded candidates. Powerful and efficient communication#R##N#systems are needed, which provide high capacities, especially at the downlink. Furthermore, interactivity is essential for#R##N#supporting the user needs and to extend the service offering. As one possible solution to meet the mentioned requirements, we#R##N#consider the combination of the cellular network UMTS and the mobile broadcast network DVB-H, which form a hybrid network.#R##N#We investigate the performance of hybrid networks and develop a system model, which describes the hybrid network and the load#R##N#switching between both networks. One of the contributions is the definition of the switching bound concept, which represents an#R##N#efficient tool to assess the necessity and the feasibility of hybrid networks and the amount of load switching. The performance#R##N#indicators cell load and grade of service are analyzed by using theoretical and realistic scenarios.
