A regional NRF may register NFs, and the registration information may include locality information for each registered NF. During synchronization with a root NRF, the regional NRF provides the locality information for each registered NF. During discovery request routing by the root NRF, the root NRF prioritizes regional NRFs having NFs that satisfy the discovery parameters of the discovery request and match the preferred locality indicated in the discovery request.

Geographically intelligent network function request routing

A method for processing NF discovery requests using prioritized lists of preferred locations includes maintaining an NF profiles database including NF profiles of producer NFs registered to provide service to other NFs and a preferred locality attribute mappings database including mappings between preferred locality attributes and prioritized lists of preferred locations. The method includes receiving, from an NF, an NF discovery request including query parameters and a preferred locality attribute. The method further includes accessing the preferred locality attribute mappings database using the preferred locality attribute and obtaining a prioritized list of preferred locations corresponding to the preferred locality attribute, accessing the NF profiles database using the query parameters and identifying NF profiles of producer NFs capable of providing a service indicated by the query parameters, and prioritizing the NF profiles according to the prioritized list of preferred locations. An NF discovery response is generated and transmitted to the NF.
