Abstract:
Methods, systems, and computer readable media for utilizing network function (NF) service attributes associated with registered network function service producers in a hierarchical network are disclosed. One method comprises receiving, by a root network function repository function (NRF) operating in a hierarchical network and from a regional NRF operating in a first region of the hierarchical network, a NF registration message or a NF update message, wherein the NF registration message or NF update message includes an NrfInfo structure that contains one or more NF service attributes specifying one or more NF services provided by at least one NF service producer registered with the regional NRF. The method further includes extracting, by the root NRF, the one or more NF service attributes from the NrfInfo structure, and creating, by the root NRF, one or more indexed entries containing the one or more NF service attributes in a local state information database.
