Abstract(in English) In the event where a large-scale disaster such as the Great East Japan Earthquake occurs, due to network control-related issues, connectivity of voice calls is often lost over a large area. At present, general measures such as 1) transmission control, 2) waiting system, and 3) limiting communication time have been proposed to secure connectivity during unforeseen disasters. To evaluate the effectiveness of such measures, it is necessary to grasp an understanding of the number of calls made by each individual immediately after the event, and record this frequency as input traffic. However, as the reactions of people during times of emergency vary widely, proper analysis and evaluation of such input traffic is fairly difficult. Consequently, a survey was performed on general public residing within the Tokyo metropolitan area, which enabled further insights into the amount of input traffic generated under the prescribed conditions. In this research, the survey results will be presented along with our proposal for ensuring connectivity.
