Methods, systems, and computer readable media for service aggregation for alternate routing of callback messages

A system for service aggregation for alternate routing of callback messages, the system comprising:

• a network function (NF) including at least one processor;
• and
• an aggregated services manager implemented by the at least one processor for registering, with an NF repository function (NRF), an NF profile of the NF including an aggregated service name representing a plurality of different service types provided by the NF, receiving requests from consumer NFs relating to the different service types, obtaining resource information from a producer NF, re-using the resource information to respond to the requests, communicating the aggregated service name to the producer NF as binding information,
• and maintaining a registered status of the aggregated service name with the NRF as long as any of the service types remain available at the NF.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• registering, by a network function (NF) implemented using at least one processor and with an NF repository function (NRF), an NF profile of the NF including an aggregated service name representing a plurality of different service types provided by the NF;
• receiving, by the NF, requests from consumer NFs relating to the different service types;
• obtaining, by the NF, and in response to the requests from the consumer NFs, resource information from a producer NF, re-using the resource information to respond to the requests, and communicating the aggregated service name to the producer NF as binding information;
• and
• maintaining, by the NF, a registered status of the aggregated service name with the NRF as long as any of the service types remain available at the NF.
