Abstract
A communication system includes a server and a plurality of terminals. The server repeatedly assigns transmission periods to the terminals in a regular order, each of the terminals being permitted as a current terminal to transmit data stored in a buffer thereof to the server during an assigned transmission period assigned thereto by the server as a current transmission period. The communication system includes: a transmission controller provided in each of the terminals for transmitting a release request notification to the server in a case where the terminal finishes data transmission before the end of the assigned transmission period assigned to the terminal, and a transmission period assigning portion provided in the server for assigning a next transmission period following the current transmission period to a next terminal different from the current terminal, in response to the release request notification.
