Methods, systems, and computer readable media for identifying, to network function (nf) discovery service consumers, nf discovery results impacted by an nf profile update

Abstract

A method for identifying cached NF discovery results impacted by an NF profile update to NF discovery service consumers includes receiving an NF discovery request including query parameters, generating an NF discovery response, communicating the NF discovery response to the NF discovery service consumer, and caching information associated with the NF discovery response. The method further includes receiving an NF update message for changing a value of at least one attribute of an NF profile of a producer NF, determining that the change in the value of at least one attribute of the NF profile of the producer NF would have impacted the NF discovery response, updating the cached information associated with the NF discovery response, and communicating, to the NF discovery service consumer, a notification message including the NF profile of the producer NF and identifying the NF discovery response as an impacted NF discovery response.
