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.

A network operating system receives a bundle file transmitted from a vendor terminal of a vendor providing a network service, the bundle file including first data defining a functional unit group that achieves the network service and second data defining a monitoring policy for the network service. The NOS constructs the functional unit group based on the first data of the bundle file when the network service is purchased by a purchaser. The NOS executes a monitoring process on the functional unit group based on information on the functional unit group to be constructed and the second data of the bundle file.

Computer system and network service construction method

A network operating system (NOS) acquires, for a plurality of network functions that achieve a network slice constructed on a mobile wireless communication network, information on an operation of each network function which is measured by one or more apparatus configured to provide at least a part of the plurality of network functions. The NOS derives an evaluation index value of each of the plurality of network functions based on the information on the operation of each of the plurality of network functions, and derives an evaluation index value of the network slice based on the evaluation index values of the plurality of network functions.

Computer system and network slice management 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.
