Abstract
A data collection scheme with an improved data collection efficiency. In order to collect data from many terminals to a center having a plurality of center service ports through a public network, terminal data are transmitted from the terminals to the center through the public network by carrying out a calling operation to call up the center at each terminal, and the terminal data received at the center service ports are collected together. At the same time, a congestion state of the center service ports is measured, and a control data for controlling the calling operation at each terminal in order to improve the measured congestion state is generated and broadcast from the center to the terminals. Then, the calling operation at each terminal is controlled according to the control data broadcast from the center. The control data indicates at least a call probability by which the calling operation at each terminal is carried out probabilistically.
