1. A method for actively obtaining producer network function (NF) reachability status information by an NF repository function (NRF) in response to an NF heart-beat failure, the method comprising:
detecting, by an NRF, an NF heart-beat failure associated with a producer NF;
querying, by the NRF and via a producer NF reachability status application programming interface (API) provided by a service communication proxy (SCP), the SCP to determine reachability status of the producer NF;
receiving, by the NRF and from the SCP, a producer NF reachability status API response message including an indication that the producer NF is reachable; and
maintaining, by the NRF and in response to receiving the indication that the producer NF is reachable, a REGISTERED status for the producer NF.
