Abstract: An object of the present disclosure is to enable band allocation on a traffic flow basis even in a real wireless network in which a terminal repeats connection/disconnection in association with movement of a person or the like.
The present disclosure relates to a control system for controlling traffic in a wireless network. The control system includes a controller that performs transmission control on a terminal and an access point. Before the access point establishes a connection with the terminal, the controller establishes a connection with the terminal using a connection sequence according to a protocol available in the wireless network, and acquires, from the terminal, information about a node number and a flow-based buffer of the terminal. After the access point establishes a connection with the terminal, the controller performs transmission control for each traffic flow accumulated in the flow-based buffer of the terminal using the acquired information about the node number and the flow-based buffer of the terminal.-

Abstract: Signal transfer devices that relay base stations of service providers that perform communication with radio terminals and an aggregation station that controls the base stations, and a route control device that controls signal distribution to user network interfaces (UNIs) and network network interfaces (NNIs) of each of the signal transfer devices, are included. The route control device includes an allocation information acquisition unit that acquires allocation information of frequency to each of the base stations; a band adjustment unit that adjusts an MBH band for each of the UNIs, on the basis of correspondence relation information representing a correspondence relation between the UNIs and the service providers, band information indicating a maximum MBH band of each of the UNIs, and the allocation information; and a distribution determination unit that determines signal distribution to each of the NNIs, on the basis of the MBH band adjusted by the band adjustment unit and configuration information representing a connection configuration of each of the signal transfer devices. The signal transfer device transmits a signal from each of the NNIs on the basis of the signal distribution to each of the NNIs determined by the distribution determination unit.

Abstract: An uplink transmission band and a downlink transmission band that are allocated to each of a plurality of users are determined based on allocation information indicating allocation of a frequency bandwidth available to each of the plurality of users, and are output as uplink transmission band allocation information and downlink transmission band allocation information, respectively. Based on the downlink transmission band allocation information, downlink signals output from a plurality of wireless control devices toward a plurality of wireless devices for each of the plurality of users, and the uplink transmission band allocation information are multiplexed, and the multiplexed signal is demultiplexed into downlink signals for each of the plurality of users and the uplink transmission band allocation information. Based on the demultiplexed uplink transmission band allocation information, the uplink transmission band allocated to each of the plurality of users is changed, and uplink signals output from the plurality of wireless devices toward the plurality of wireless control devices for each of the plurality of users are multiplexed according to the changed uplink transmission band and then, the multiplexed signal is demultiplexed into the uplink signals for each of the plurality of users.

Abstract: To solve the above problem, the present invention aims to provide a controller, a communication system, a control method, and a program capable of performing transmission scheduling to avoid mutual interference in a plurality of wireless networks.
A controller 13 according to the present invention includes a scheduler SCH3 that calculates a transmission schedule for packets to be transmitted from buffers (FB1, FB2) on the basis of the amount of packets stored in a database DB in each predetermined period, and, when calculating the transmission schedule, imposes a restriction to prevent a total amount of packets to be transmitted from all the buffers (FB1, FB2) included in a network NW #j from exceeding the product of the throughput of each network NW #j and the predetermined period.-
