Impact of LTE and DVB-NGH cooperation on QoS of Mobile TV users

The LTE/DVB convergence to offer users a seamless Mobile TV service is at the heart of the emerging DVB-NGH standard. Most of the works addressing this issue focused solely on the impact of such convergence in terms of capacity gains brought by LTE and coverage gains brought by DVB. To the best of our knowledge, the impact of such convergence on the Mobile TV users´ QoS has not been addressed yet and is the focus of our present work. We specifically evaluate the users´ QoS in terms of quantifiable metrics, notably the probability of service degradation due to non availability of LTE bearers, its frequency and duration, and show how these metrics evolve with varying traffic load and in different network configurations.
