    Abstract: To provide a control device that can prevent an increase in a processing load and that can effectively allocate a radio resource. A control device (30) according the present disclosure includes: a deciding unit (31) configured to decide whether or not an interval between generation of a first flow that is generated when performing radio communication between a communication terminal (10) and a base station (20) and generation of a second flow that is generated after the generation of the first flow exceeds a permissible delay time of the first flow; and a determination unit (32) configured to determine deletion of non-transmitted data related to the communication terminal (10) after lapse of the permissible delay time of the first flow when it is decided that the generation interval exceeds the permissible delay time of the first flow.

    Abstract: The present invention enhances the quality that a user feels in a wireless communication system. This base station device 60 is provided with: a calculation unit 63 which calculates a data transmission start deadline at which data transmission to a wireless terminal device 70 can be completed by a completion deadline for transmission to the wireless terminal device 70 set on the basis of information about the application, when the data, which is transmitted to the wireless terminal device 70 by the application executed by a server device 80 in response to a request from the wireless terminal device 70, is transmitted to the wireless terminal device 70 by using a wireless resource; and an allocation unit 64 which allocates a wireless resource necessary for the transmission of the corresponding data to the wireless terminal device 70 on the basis of the transmission start deadline and the current time.

    Abstract: A base station apparatus is connected to a plurality of transmission/reception points each switching a transmission scheme according to reception environment of wireless terminal and providing service to wireless terminal. The base station apparatus includes a history recording part recording history of beam and transmission scheme selected by wireless terminal with respect to each transmission/reception point; a calculation part calculating a second throughput when service is received using one or more beams being candidates for selection by wireless terminal among beams transmitted by a second transmission/reception point different from a first transmission/reception point connected to wireless terminal; and a transmission/reception point selection part providing service from the second transmission/reception point to wireless terminal by the beam and the transmission scheme corresponding to the second throughput subject to satisfying a predetermined condition with respect to the first throughput being the measured throughput with the first transmission/reception point connected to wireless terminal.
