An objective is to provide a management apparatus, a management method, and a management program that can eliminate interference without involving complicated control between cells. If interference is occurring between a first RU (Radio Unit) connected to a first virtualized DU (vDU: virtualized Distributed Unit) and a second RU connected to a second vDU different from the first vDU, a connection destination determination unit () determines a connection destination vDU to which the first RU and the second RU are to be connected, so that the first RU and the second RU in which the interference is occurring are connected to the same vDU. A control unit () implements control such that the first RU and the second RU in which the interference is occurring are connected to the connection destination vDU.

Management apparatus, management method, and management program

An objective is to provide a control system, a control method, and a control program that can appropriately set a base station forming a small cell. A detection unit () detects a prescribed object in an image acquired by a camera. An extraction unit () extracts, from the image, object information relating to the detected object. A prediction unit () predicts, based on the object information, communication demand for a base station from a radio terminal that the detected object has. A determination unit () determines a setting of the base station based on the predicted communication demand. A control unit () controls the base station in accordance with the determined setting.

In order to connect a radio terminal in a heterogeneous network environment to a connection destination in an appropriate frequency band, a management device comprises: a located-area information acquisition unit that acquires located-area information of the radio terminal; a first base station identification unit that uses the located-area information to identify a first base station forming a macrocell; a second base station identification unit that uses the located-area information to perform a first assessment for assessing whether or not the radio terminal is within one of the small cells, and that, when the radio terminal is within one of the small cells, identifies a second base station forming the small cell; and a high-speed communication requirement assessment unit that performs a second assessment for assessing whether or not the radio terminal requires high-speed communication based on at least a predicted traffic demand volume from the radio terminal.

Management device, management method, and management program

A management apparatus of a RAN that is shared by a plurality of operators, the RAN comprising: a CU; a first DU that is communicably connected to the CU; a second DU that is communicably connected to the CU; and an RU that are communicably connected to the first DU and the second DU, wherein the management apparatus comprises a processor that executes: until an amount of traffic being monitored in the RAN reaches a predetermined range, selecting one operator, among the plurality of operators, that has entered into a guarantee type Service Level Agreement (SLA) with a user; and transmitting instructions to the CU, the first DU, and the second DU to cause the second DU to process at least a portion of the data for a User Equipment that is communicably connected with the RU and that has entered into the guarantee type SLA with the selected operator.

Apparatus and method for distributed data processing in shared RAN

A management apparatus in a radio access network including RUs (Radio Units) and vDUs (virtual Distributed Units), the management apparatus comprising: a monitoring unit configured to acquire load states of the respective vDUs; and a control unit configured to determine, among the vDUs, based on the load states that have been acquired, a first vDU in which a load should be lowered and a second vDU for receiving part of the load from the first vDU, to determine, among RUs connected to the first vDU, an RU for which a connection destination is to be changed to the second vDU, and to change the connection destination of the determined RU from the first vDU to the second vDU.

An objective is to suppress degradation of the usability of radio terminals even in cases in which the modes of use of the radio terminals fluctuate. A placement change determiner () determines, based on information associated with conditions or future conditions estimated from the conditions in a service area to which one or more RUs (Radio Units) in a mobile communication system belong, a placement change regarding at least one NF (Network Function) among NFs in the mobile communication system. A placement destination determiner () determines, based on the information, an NF to be changed and a placement destination of the NF to be changed. A deployer () executes the placement change by instantiating the NF to be changed at the placement destination.

Deployment control system, deployment control method, and deployment control program

A network controller comprising one or more processors and memories in order to make it possible to achieve both continuous operation of a route search system and energy consumption reduction or leveling used resources. The one or more memories store one or more programs. The one or more processors realize, by reading the one or more programs, an operating state information acquirer, a route information acquirer, and an activation request generator. The operating state information acquirer acquires operating state information regarding base stations. The route information acquirer acquires route information indicating a navigation route determined from one or more route candidates from a starting point to a goal point. The activation request generator generates, based on the operating state information regarding each base station corresponding to each area through which the determined navigation route passes, a request for activating each base station in an off state corresponding to each area through which the determined navigation route passes.

The present disclosure relates to resource sharing between clouds. According to the present disclosure, a control apparatus comprises: a resource monitor, a resource decider, a secondary cloud determiner, and a deployer. The resource monitor monitors a resource usage state of a cloud in a cloud group. The resource decider, with a creation request for a new application to a primary cloud in the cloud group serving as a trigger, decides whether or not a resource for deploying all components for constructing the new application is in the primary cloud. Based on the size of available resources if a surplus component that cannot be deployed in the primary cloud is deployed in a cloud other than the primary cloud in the cloud group, the secondary cloud determiner determines a secondary cloud in which the surplus component is to be deployed. The deployer deploys the surplus component in the secondary cloud.
