Abstract

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.

First claim

1 . A management system comprising
an NFVI (Network Function Virtualization Infrastructure) which, when a VNF (Virtualized Network Function) in which an autodiscovery flag included in setting information is set to on does not exist, performs autodeployment of the nonexistent VNF; a DB (DataBase) which stores setting information for a target cluster within the NFVI that is an upgrade target; an OSS (Operation Support System) 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 (Virtualized Infrastructure Manager) which restores the work-processed setting information to the upgraded target cluster.

2 . The management system according to claim 1 , wherein, in the work process of the OSS,
when the autodiscovery flag is in an on state when upgrading the target cluster, the autodiscovery flag is set to an off state in which autodeployment is not performed, and after completion of the upgrade of the target cluster, the autodiscovery flag is set to the on state in which autodeployment is performed.

3 . The management system according to claim 2 , wherein the autodiscovery flag is put in the on state by restoring setting information of the on state.

4 . The management system according to claim 1 , wherein the autodiscovery flag is information indicating whether or not autodeployment is to be performed on the VNF.

5 . An upgrade method for a cluster that constructs a RAN and is realized by virtualization infrastructure, comprising:
storing setting information for a target cluster, which is an upgrade target, in a DB; performing a work process on an autodiscovery flag which is included in the setting information for the target cluster stored in the DB and indicates whether or not autodeployment is to be performed; and restoring the setting information to the upgraded target cluster.
