Easier to connect calls during disaster congestion

Control to induce voluntary reduction of call duration

Abstract

Voice call is still one of the most important means of communication in the aftermath of a disaster. However, there is the problem of low call-completion ratio. We propose a control to reduce congestion by restricting the period during which users can make a call according to their phone numbers, and by informing them this restriction. It achieves a higher call-completion ratio because of the smaller number of users to make a call. Furthermore, we found through our experiments that it enables users to reduce their communication demand (holding time) voluntarily and gives less stress to them than the conventional control. We plan to reduce disaster congestion in a way that accords with human psychology.
