1. A method for accessing data in a Unified Data Repository (UDR), the method comprising:
storing, for a Data Set provided in the UDR for a plurality of Network Function (NF) service consumers, a plurality of Service Based Architecture (SBA) services, wherein each of the plurality of SBA services is associated with one or more Data Subsets included in a plurality of Data Subsets associated with the Data Set, and further wherein each of the plurality of SBA services is provided for one or more NF service consumers included in the plurality of NF service consumers;
registering, from the UDR toward a Network Repository Function (NRF), (i) a plurality of SBA service identifiers identifying the plurality of SBA services handled at the UDR and (ii) an UDR identifier identifying UDR, wherein each of the plurality of SBA service identifiers is different from the UDR identifier and an NF identifier identifying an NF;
after storing the plurality of SBA services and registering the plurality of SBA service identifiers, receiving, at the NRF from an NF service consumer, a service discovery request with an SBA service identifier identifying a particular SBA service;
based on receiving the service discovery request with the SBA service identifier identifying the particular SBA service, transmitting, from the NRF toward the NF service consumer, the UDR identifier identifying the UDR handling the particular SBA service identified by the SBA service identifier;
after receiving the UDR identifier identifying the UDR handling the particular SBA service identified by the SBA service identifier, transmitting, from the NF service consumer toward the UDR identified by the UDR identifier, a service request for the particular SBA service; and
after transmitting the service request for the particular SBA service, receiving, at the NF service consumer from the UDR, information data relating to the one or more Data Subsets associated with the particular SBA service identified by the SBA service identifier.
