METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR OPTIMIZED NETWORK FUNCTION (NF) DISCOVERY AND ROUTING USING SERVICE COMMUNICATIONS PROXY (SCP) AND NF REPOSITORY FUNCTION (NRF)

Abstract:

A method for optimized NF discovery and routing includes, at an SCP, receiving a discovery request message or generating a discovery request message in response to a received service request message with a 3gpp-Sbi-Discovery header. The SCP modifies the discovery request message to identify as unhealthy at least one service endpoint and service name combination associated with at least one producer NF instance capable of providing a service identified in the discovery request message or the service request message The SCP forwards the discovery request message to the NRF. The NRF creates a list of service profiles of producer NF instances capable of providing the service identified in the discovery or service request message and excludes, from the list, at least one service profile of the at least one producer NF instance corresponding to the endpoint and service name combinations identified as unhealthy in the discovery request message.
