A radio network system comprising: a central unit; a plurality of data managers connected to the central unit; and one or more remote radio units that are connected with the respective data managers and each performs radio communication with a corresponding user terminal, the central unit comprising a data broadcasting unit that broadcasts, to the data managers via mobile front-haul, downlink data destined for user terminals received from a host network, and a scheduling unit that executes scheduling for allocating radio resources of the remote radio units to radio transmission of the downlink data simultaneously with broadcasting of the downlink data, the data managers each comprising a data accumulation unit that temporarily accumulates the downlink data broadcast from the central unit, and a data selection unit that selects, based on an allocation result obtained by the scheduling, downlink data allocated to the radio resource of a corresponding remote radio unit, which corresponds to the self data manager among the remote radio units, from the downlink data accumulated in the data accumulation unit, transfers the selected downlink data to the corresponding remote radio unit, and discards, from the data accumulation unit, the downlink data allocated to the radio resources of the remote radio units other than the corresponding remote radio unit, and the remote radio units each comprising a radio transmission unit that performs, based on the allocation result obtained by the scheduling, radio transmission of the downlink data transferred from the data manager to the corresponding user terminal using the designated radio resource. a central unit; a plurality of data managers connected to the central unit; and one or more remote radio units that are connected with the respective data managers and each performs radio communication with a corresponding user terminal, the central unit comprising a data broadcasting unit that broadcasts, to the data managers via mobile front-haul, downlink data destined for user terminals received from a host network, and a scheduling unit that executes scheduling for allocating radio resources of the remote radio units to radio transmission of the downlink data simultaneously with broadcasting of the downlink data, the data managers each comprising a data accumulation unit that temporarily accumulates the downlink data broadcast from the central unit, and a data selection unit that selects, based on an allocation result obtained by the scheduling, downlink data allocated to the radio resource of a corresponding remote radio unit, which corresponds to the self data manager among the remote radio units, from the downlink data accumulated in the data accumulation unit, transfers the selected downlink data to the corresponding remote radio unit, and discards, from the data accumulation unit, the downlink data allocated to the radio resources of the remote radio units other than the corresponding remote radio unit, and the remote radio units each comprising a radio transmission unit that performs, based on the allocation result obtained by the scheduling, radio transmission of the downlink data transferred from the data manager to the corresponding user terminal using the designated radio resource.
