Abstract:
1. A time division multiplexing communication system, comprising: a plurality of communication devices; a switch device having a plurality of terminals to which at least the plurality of communication devices are respectively connected, a switch unit capable of mutually connecting all of the plurality of terminals and individually connecting the plurality of terminals, and a switch control unit for controlling a connection status of the switch unit; and a transmittal right control unit for managing the connection status of the switch unit, which is connected to at least one of the plurality of terminals, for (a) receiving, from each of the communication devices, a request for time to communicate with another communication device, with all of the plurality of terminals being mutually connected, (b) determining, by time division multiplexing, allocation of the time to communicate without signal interference among the communication devices at the request in a way that (i) communications among the communication devices in non-overlapping combinations are performed in a same time period, and (ii) communications among the communication devices in overlapping combinations are performed in a different time period, (c) notifying each of the communication devices of the determined allocation of the time, and (d) instructing the switch control unit such that a switch of a connection between the plurality of terminals are individually controlled based on the determined allocation of the time.
