Application level mechanisms for service continuity in an LTE multimedia broadcast service

In LTE broadcast, maintaining the service continuity for moving users is a challenge that is still not solved. In this paper, we focus on the problem of users moving between different MBMS areas, taking into account that some characteristics of a service might be different in different areas. Specifically, we focus on minimizing the impact of a handover at the application level, in order to make it possible for a video broadcast application to maintain service continuity when parameters such as video bitrate or video codecs change between different areas, for example from a dense urban deployment area to a sub-urban deployment.
