Abstract

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.

First claim

1 . A management apparatus comprising:
a connection destination determination unit that, if interference is occurring between a first Radio Unit (RU) connected to a first virtualized Distributed Unit (vDU) and a second RU connected to a second vDU different from the first vDU, 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; and a control unit that implements control such that the first RU and the second RU in which the interference is occurring are connected to the connection destination vDU.

2 . The management apparatus according to claim 1 , further comprising
an available resources checking unit that checks available resource conditions in the first vDU and available resource conditions in the second vDU, wherein the connection destination determination unit determines that either the first vDU or the second vDU is to be set as the connection destination vDU based on at least the available resource conditions in the first vDU and the available resource conditions in the second vDU.

3 . The management apparatus according to claim 2 , wherein the connection destination determination unit determines that the vDU in which a size of available resources is larger is to be set as the connection destination vDU.

4 . The management apparatus according to claim 2 , wherein the connection destination determination unit determines the connection destination vDU such that a difference between a size of available resources in the first vDU and a size of available resources in the second vDU is made small after connection destination control.

5 . The management apparatus according to claim 2 , wherein
the available resources checking unit comprises a prediction unit that predicts future resource usage amounts in the first vDU and the second vDU, and the available resources checking unit checks sizes of the available resources based on the future resource usage amount in the first vDU and the future resource usage amount in the second vDU.

6 . The management apparatus according to claim 2 , wherein the connection destination determination unit further, in accordance with comparison results between a prescribed threshold value and a size of available resources in the connection destination vDU, (i) maintains the connection destination vDU, or (ii) determines that a third vDU different from the first vDU and the second vDU is to be set as the connection destination vDU, and
when the connection destination determination unit determines that the third vDU is to be set as the connection destination vDU, the control unit instantiates a new vDU as the third vDU.

7 . The management apparatus according to claim 1 , wherein
the connection destination determination unit determines that a third vDU different from the first vDU and the second vDU is to be set as the connection destination vDU, and the control unit instantiates a new vDU as the third vDU.

8 . The management apparatus according to claim 1 , wherein the control unit
scales out the vDU, of the first vDU and the second vDU, that has been determined to be the connection destination vDU, and scales in the vDU, of the first vDU and the second vDU, that has not been determined to be the connection destination vDU.

9 . A management method that is executed by one or more processors, the management method including:
if interference is occurring between a first RU connected to a first virtualized DU and a second RU connected to a second virtualized DU different from the first virtualized DU, determining a connection destination virtualized DU 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 virtualized DU; and implementing control such that the first RU and the second RU in which the interference is occurring are connected to the connection destination virtualized DU.
