An inventory database and an active inventory each store inventory data indicating a current status of an influence relationship between elements included in the communication system. An E2EO module detects occurrence of an event in a specific element included in the communication system. The E2EO module identifies at least one other element having an influence relationship with the specific element based on the inventory data. The E2EO module identifies a cause of the event based on a status of the at least one other element.

Cause specifying system and cause specifying method

Provided are a performance index value calculation system and a performance index value calculation method which are capable of reducing time and labor for an operation of a communication system. A monitoring management module identifies, based on inventory data indicating a current status of a configuration of an element group included in a communication system and on calculation logic data indicating a condition to be satisfied by an element used for calculating a desired performance index value, a monitoring item for the element, and a calculation logic for calculating the desired performance index value, an element that satisfies the condition from the element group indicated by the inventory data. The monitoring management module calculates the desired performance index value by applying the calculation logic indicated by the calculation logic data to a performance index value of the monitoring item for the identified element.

Performance index value calculation system and performance index value calculation method

An E2EO module determines, in response to determination that a new element linked to an already installed element included in the communication system is to be added to the communication system, a location at which the new element is to be constructed based on new topology data including the new element and a current location of the already installed element indicated by location data.

Location determination system and location determination method

An E2EO module identifies a monitoring item for which a user is to be provided with a monitoring result. The E2EO module determines, based on the identified monitoring item, an exclusive-use element from an element group including at least one of a software element group that achieves a network service or a hardware element group in which the software element group is implemented. The E2EO module, a configuration management module, and a container management module construct the software element group that achieves the network service in a configuration in which at least the exclusive-use element is exclusively used by the user.

Network service build system and network service build method

Provided are a performance index value calculation system and a performance index value calculation method which are capable of reducing time and labor for an operation of a communication system. A monitoring management module identifies a specific type of element included in a communication system based on inventory data indicating a current status of a link between elements included in the communication system and on calculation logic data indicating a calculation logic for calculating a performance index value of the specific type of element based on performance index values of an element group linked to the element. The monitoring management module identifies the performance index value of each of a plurality of elements included in the element group linked to the identified specific type of element. The monitoring management module calculates the performance index value of the specific type of element by applying the calculation logic indicated by the calculation logic data to the performance index value identified for each of the plurality of elements.

An E2EO module stores action data which is linked to a condition relating to a combination of an operation status of a specific type of element and an operation status of another type of element linked to the specific type of element, and which indicates an action to be executed on the specific type of element that satisfies the condition. The E2EO module identifies, based on the current status indicated by the inventory data, a combination of a current operation status of the specific type of element included in the communication system and a current operation status of another type of element linked to the specific type of element. The E2EO module executes, when the identified combination satisfies the condition linked to the action data, the action indicated by the action data on the specific type of element.

Action execution system and control method thereof

A method includes generating, by a processor, a network slice bundle universally unique identifier (slice_bundle_UUID) for a network slice bundle; and generating, by the processor, a slice catalog slice_bundle_UUID, based on the slice_bundle_UUID, for use by a slice catalog; parsing and locating in the slice catalog, by the processor, one or more stored network service bundle references, based on a network service UUID (NS_UUID) referenced in the network slice bundle; and creating, by the processor, a relationship between one or more stored network services in the slice catalog and the network slice bundle.

System and method for design of a network slice

Application artifact registration is performed by receiving a bundle service specification configured for deployment of a software service in a cloud native environment, transferring a bundle from an original address indicated in the bundle service specification to an object storage at a principal address, attaching, to the bundle service specification, a bundle identifier and the principal address, extracting a plurality of artifacts from the bundle, each of the plurality of artifacts being stored in the object storage at a subordinate address, and creating one or more artifact service specifications, each artifact service specification representing one or more of the plurality of artifacts, each service specification representing the corresponding subordinate address, an artifact identifier, and an artifact type of each represented artifact.

Application artifact registration

A method includes creating a package of an application, registering the package with an orchestrator, triggering instantiation of the application in the orchestrator, generating initial configuration files for the instantiation of the application, changing an application state of the application to a planned state, changing the application state to a Keycloak state in response to obtaining client identification of the Keycloak information for the application, changing the application state to an instantiated state in response to deploying the application on the set of target servers, changing the application state to a configured state in response applying daily configuration files to perform daily configuration of the application in the set of target servers, and changing the application state to a monitored state in response to monitoring the application in the set of target servers by an observability framework tool.
