A method for providing service based interface (SBI) support for network elements (NEs) not supporting SBI service operations includes receiving SBI configuration parameters for an NE not supporting SBI service operations. The method further includes establishing a connection with the NE not supporting SBI service operations. The method further includes registering, with a network function (NF) repository function (NRF) and using the SBI configuration parameters, the NE not supporting SBI service operations. The method further includes monitoring, over the connection, status of the NE not supporting SBI service operations. The method further includes updating, with the NRF, the status of the NE not supporting SBI service operations.

A method for optimizing network traffic distribution using timeslot-based tracked producer network function (NF) performance during producer NF selection is performed at a service communication proxy (SCP) including at least one processor. The method includes tracking a performance characteristic of producer NFs across different timeslots. The method further includes receiving, from a consumer NF, a service based interface (SBI) service request. The method further includes identifying eligible producer NFs capable of handling the SBI service request. The method further includes selecting, from the eligible producer NFs, in a manner that at least partially overrides priorities of the eligible producer NFs, and based on the tracked performance characteristic across the different timeslots, a producer NF to handle the SBI service request. The method further includes forwarding the SBI service request to the producer NF.

A method for feedback-based network slice management includes steps performed at a network slice management function (NSMF) including at least one processor. The steps include subscribing, via a network data analytics function (NWDAF) subscription interface of the NSMF, directly with the NWDAF to create a subscription to be notified of network slice load information and specifying, as part of the subscription, network slice load information report generation criteria defined by the NSMF. The steps further include receiving, directly from the NWDAF, via the NWDAF subscription interface of the NSMF and in response to the NSMF-defined network slice load information report triggering criteria being met, network slice load information. The steps further include determining, based on the network slice load information, that a network slice resource allocation change is needed. The steps further include, in response to determining that a network slice resource allocation change is needed, dynamically changing the network slice resource allocation during operation of a network slice.
