Methods, systems, and computer readable media for generating, conveying, and using attempted producer network function (nf) instance communication information

A system for generating, conveying, and using attempted producer network function (NF) instance communication information, the system comprising:

• a network node including at least one processor and a memory;
• and
• a service communication proxy (SCP) implemented using computer executable instructions stored in the memory and executed by the at least one processor for receiving, from a sender, a first service based interface (SBI) request message, attempting to obtain a service requested by the first SBI request message from at least one producer NF instance, receiving at least one error response or failing to receive a response from the at least one producer NF instance;
• generating, from the at least one error response or the failing to receive a response from the at least one producer NF instance, attempted producer NF instance communication information, and communicating, to the sender, the attempted producer NF instance communication information.

One or more non-transitory computer readable media comprising computer-executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• receiving, from a sender, a first service based interface (SBI) request message;
• attempting to obtain a service requested by the first SBI request message from at least one producer network function (NF) instance;
• receiving at least one error response from the at least one producer NF instance or failing to receive a response from the at least one producer NF instance;
• generating, from the at least one error response or the failing to receive a response from the at least one producer NF instance, attempted producer NF instance communication information;
• and
• communicating, to the sender, the attempted producer NF instance communication information.
