Abstract: A communication system including: one or more terminal accommodation stations that perform communication with one or more terminals; a plurality of communication stations that is connected to the one or more terminal accommodation stations directly or via another device; a cooperation information collection unit that acquires cooperation information indicating a state of communication between the communication station and the one or more terminals, from the communication station; an optical path switching control unit that controls switching of an optical path between the one or more terminal accommodation stations and the plurality of communication stations in a case where it is determined that switching of the optical path between the one or more terminal accommodation stations and the plurality of communication stations is necessary on the basis of the cooperation information; and a sleep control unit that causes a communication station capable of sleep to transition to a sleep state before the switching o

Abstract: A control device that includes a sleep detection unit that detects a migration of a communication station, which is connected to a first path via an optical distribution unit that outputs signals outputted from one or more terminal accommodation stations to another path and not via a fronthaul multiplexer that multiplexes and outputs signals outputted from the one or more terminal accommodation stations, to a sleep state among a plurality of communication stations that accommodates the one or more terminal accommodation stations that communicate with a terminal, and a switching signal transmission unit that transmits a switching signal to the optical distribution unit that instructs to switch the terminal accommodation station accommodated in the communication station that has migrated to the sleep state to be accommodated in the communication station connected to a second path via the optical distribution unit and the fronthaul multiplexer when the sleep detection unit detects the migration of the communicat

Abstract: A management control device includes a linkage information collection unit that acquires linkage information indicating a communication state with one or more terminals from each of one or more first base stations which perform radio communication with the one or more terminals and one or more second base stations which form a smaller range communication area than that of the one or more first base stations in a communication area formed by the one or more first base stations and perform the radio communication with the one or more terminals, an analysis unit that determines whether or not an optical path switching is necessary on the basis of the linkage information, an optical path switching control unit that controls the switching of optical paths of the one or more first base stations or optical paths of the one or more second base stations when it is determined that the optical path switching is necessary, and a sleep control unit that shifts the one or more first base stations or the one or more second

Abstract: A management control device includes: a cooperation information collection unit configured to acquire, at a predetermined period, cooperation information indicating a state of communication with one or more terminals from one or more base stations that perform wireless communication with the one or more terminals; an analysis unit configured to determine whether switching of an optical path is necessary based on the cooperation information; an optical path switching control unit configured to transmit switching destination information including information on a destination of optical path switching to a transfer device that switches the optical path connected to the one or more base stations when it is determined that switching of the optical path is necessary, and instruct a base station that is a source of the optical path switching to change a connection of a terminal associated with switching of the optical path; and a sleep control unit configured to transition the base station that is the source of the

Abstract: Provided is a communication system including: one or more wireless stations that perform wireless communication with one or more terminals; a plurality of distributed stations connected, directly or via another device, to the one or more wireless stations; a cooperation information collection unit that acquires, at a predetermined cycle, cooperation information indicating a state of communication between the plurality of distributed stations and the one or more terminals; an optical path switching control unit that controls switching of an optical path between the one or more wireless stations and the plurality of distributed stations when it is determined, on the basis of the cooperation information, that the switching of the optical path between the one or more wireless stations and the plurality of distributed stations is required; and a sleep control unit that causes each of the distributed stations that can sleep to transition to a sleep state after the switching of the optical path is performed.

Abstract: A control device including a collection unit that acquires, at a predetermined cycle, cooperation information, which is information indicating a communication state between a communication system that includes a wireless station including an antenna and an allocation device that allocates a wavelength, and a terminal to be communicated, an analysis unit that analyzes the communication state in the communication system on the basis of the cooperation information, and an allocation control unit that controls execution of wavelength allocation by the allocation device on the basis of an analysis result of the analysis unit.
