ABSTRACT
In this paper, we present an approach for achieving application driven seamless handover across different wireless access networks. The target is thereby to eliminate any content loss while minimizing the interruption duration that is perceived by the user during the handover procedure. Ultimately, the user experience will greatly benefit from the usage of the most suitable network access technology. The focus is set on Mobile TV applications, where an ongoing streaming session experiences an application-controlled handover from DVB-H to an alternative unicast access (e.g. Wi-Fi or 3G) or vice versa. A handover decision algorithm is also presented, aiming at enhancing the overall system stability by adjusting to the dynamic conditions of the broadcast channel.
