Abstract: 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.

Abstract: Provided are a network service construction system and a network service construction method which are capable of flexibly constructing network services that satisfy various needs. A purchase management module receives service requirement data indicating a service requirement. An E2EO module and an inventory management module identify, based on the service requirement data, a configuration of a functional unit group that achieves a network service.

Abstract: 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.

Abstract: A CI/CD assist device accepts a test template in which some of fields of test content is set to a variable field in which a value is variable. An NOS sets a value compatible with a first environment in the variable field of the test template to generate test data compatible with the first environment. A test device conducts a test on a network service in the first environment by using the test data compatible with the first environment. An NOS sets a value compatible with a second environment in the variable field of the test template to generate test data compatible with the second environment. A test device conducts a test on the network service in the second environment by using the test data compatible with the second environment.
