A First Step Towards Call Survivability in Cellular Networks

Despite recent advancements in cellular phone network infrastructure, survivability of the calls is still an open issue. Important business calls and tele-conferences cannot benefit from mobility because landlines are preferred owing to their reliability and tolerance to failures. In this paper, we present a framework to improve call survivability by monitoring the user’s location and intimating him about the possibility of loss of connectivity, interference, and room schedules that might disrupt conversation. In addition, if a call drops because of unforeseeable circumstances like battery failure or cell-phone damage then the call is switched to the nearest available device capable of streaming voice.
