  • Patent number: 11399340
    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.
    Type: Grant

  • Publication number: 20210076220
    Abstract: A management device for managing a radio access network includes: a RAN slice management unit configured to manage a slice of the radio access network; a radio resource management unit configured to abstract and manage a radio resource possessed by a radio base station included in a radio network; an optical resource management unit configured to abstract and manage an optical resource possessed by an optical communication device included in an optical network; and a base station resource management unit configured to abstract and manage a base station resource possessed by a base station device included in a base station network. When a slice generation request is received from a higher-level management device, the RAN slice management unit determines an abstracted radio resource, an abstracted optical resource and an abstracted base station resource to be assigned to a slice, based on requested performance of the slice.
