COMMUNICATION SYSTEM, COMMUNICATION TERMINAL, AND COMMUNICATION METHOD

摘要

A terminal mode of at least a part of terminals in a centralized control area and terminals in a distributed control area is set to a time division control mode for performing communication in a time division manner. The terminals in the centralized control area, the terminal mode of which is other than the time division control mode, are set in a centralized control mode. The terminals, the terminal mode of which is other than the time division control mode, are set in a distributed control mode. The terminals set in the time division control mode perform transmission in a communication period in which communication is permitted. The terminals set in the centralized control mode and the terminals set in the distributed control mode perform communication without depending on the communication period.

1. A communication system comprising a plurality of communication terminals, the communication system being capable of setting a centralized control area where centralized control for carrying out communication according to control by a master terminal is carried out and a distributed control area where distributed control for carrying out communication according to autonomous distributed control is carried out, wherein
the communication system sets a terminal mode of the communication terminals including the communication terminal located in a boundary between the centralized control area and the distributed control area to a time division control mode for performing communication in a time division manner, sets the communication terminal in the centralized control area, the terminal mode of which is other than the time division control mode, in a centralized control mode, and sets the communication terminal in the distributed control area, the terminal mode of which is other than the time division control mode, in a distributed control mode, the communication terminal set in the time division control mode performs transmission in a communication period in which communication is permitted, and the communication terminal set in the centralized control mode and the communication terminal set in the distributed control mode perform communication without depending on the communication period.
