  • Publication number: 20210153113
    Abstract: A controller of a radio access network calculates physical path resource information which is resource information about physical paths between devices in the network, and abstract path resource information which expresses the physical path resource information in a representative manner. When receiving a request to create a slice, the controller determines whether a slice that satisfies a requested condition is creatable based on the abstract path resource information and, when determining that the slice that satisfies the requested condition can be created, creates the slice by selecting a physical path that satisfies the requested condition based on the physical path resource information.
