Patent ID: 11864093

Abstract:
A method for communicating delegated NF discovery results between SCPs and using the delegated NF discovery results for alternate SBI service request routing includes receiving, at a first SCP and from a consumer NF instance, an SBI service request. The method further includes determining that delegated NF discovery is required, and, in response, performing delegated NF discovery on behalf of the consumer NF instance. The method further includes receiving an NF discovery response including delegated NF discovery results. The method further includes sending the SBI service request including the delegated NF discovery results to a second SCP. The method further includes receiving, at a second SCP, the SBI service request including the delegated NF discovery results, forwarding the SBI service request towards a first producer NF instance selected by the first SCP, detecting failure of routing or processing of the SBI service request, and using the delegated NF discovery results for alternate routing of the SBI service request.
