A Proposal of a Communication-Broadcasting Integrated System to Support Communication and Navigation during Disasters

Often, when a base transceiver station malfunctions, the users in its area cannot communicate. In this paper, we propose a communication support system that will guide users to available base transceiver stations in disasters such as earthquakes, reporting the status of available base transceiver stations as a data stream on digital TV. In addition, we propose a user navigation algorithm to deal with network congestion at the available base transceiver stations, and evaluate its validity with numerical simulation. Finally, we show an example of its implementation.
