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

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.

Network controller for coordinating base station operation with routing

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, by reading the one or more programs, realize a user terminal traffic information acquirer, a traffic demand predictor, a route information acquirer, a route determiner, an operating state information acquirer, and an activation request generator. A navigation route is determined from one or more route candidates based on traffic demand prediction information predicting future traffic demand based on user terminal traffic information. Each base station in an off state corresponding to each area on the determined navigation route is activated.

Dynamic changing of navigation based on user's predicted future traffic demand

An Open Radio Access Network Radio Unit (O-RU) including a Radio Frequency (RF) unit and a baseband unit, wherein: the baseband unit includes two or more digital signal processing units; the two or more digital signal processing units are configured to execute digital signal processing with respectively defined higher-level units; and the baseband unit is configured so as to be able to make some of the two or more digital signal processing units execute the digital signal processing and so as to be able to switch between the digital signal processing units that are made to execute the digital signal processing.

O-RU and management method

To enable automatic reconstruction when upgrading a cluster realized by virtualization infrastructure without performing manual reconstruction such as resetting, a management system comprising: an NFVI which, when a VNF in which an autodiscovery flag included in setting information is set to on does not exist, performs autodeployment of the nonexistent VNF; a DB which stores setting information for a target cluster within the NFVI that is an upgrade target; an OSS which performs a work process on the autodiscovery flag included in the setting information for the target cluster stored in the DB; and a VIM which restores the work-processed setting information to the upgraded target cluster.

Management system, and method for upgrading cluster

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.
