1. A method for communicating delegated network function (NF) discovery results between service communication proxies (SCPs) and using the delegated NF discovery results for alternate service based interface (SBI) service request routing, the method comprising:
receiving, at a first SCP and from a consumer NF instance, an SBI service request;
determining, by the first SCP, that delegated NF discovery is required, and, in response, performing delegated NF discovery on behalf of the consumer NF instance;
receiving, by the first SCP, an NF discovery response including delegated NF discovery results;
sending, by the first SCP and to a second SCP, the SBI service request and including, in the SBI service request, the delegated NF discovery results; and
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.
