摘要： 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 (510) 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 (520) determines, based on the information, an NF to be changed and a placement destination of the NF to be changed. A deployer (530) executes the placement change by instantiating the NF to be changed at the placement destination.

摘要： 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 (120) 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 (130) implements control such that the first RU and the second RU in which the interference is occurring are connected to the connection destination vDU.

摘要： 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 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.

摘要： An objective is to provide a management apparatus, a management method, and a management program that can appropriately operate a virtualized DU in a RAN.
A management apparatus (500) manages a virtualized DU (Distributed Unit) in a base station forming a radio communication cell, constructed from one or more virtualized components. A virtualized DU monitoring unit (510) monitors, as a usage status value, a radio terminal accommodation rate in the virtualized DU or a traffic accommodation rate in the virtualized DU. A virtualized DU setting determination unit (520) determines a setting in the virtualized DU based on the usage status value and a deletion allowance requirement. The virtualized DU setting determination unit (520) determines that the virtualized DU is to be deleted if the usage status value is less than a first threshold value and the deletion allowance requirement is satisfied, and determines that the virtualized DU is to be scaled in if the usage status value is less than the first threshold value and the deletion allowance requirement is not satisfied.
