Service management orchestration driven network energy saving using o1 interface

A Service Management and Orchestration (SMO) of an Open Radio Access Network (O-RAN) configured to:

• receive network energy saving (NES) information from at least one of an O-RAN Distributed Unit (O-DU) and an O-RAN Centralized Unit (O-CU), wherein the NES information includes capability exposing information received from an O-RAN Radio Unit (O-RU);
• determine based at least in part on the NES information, whether to activate an NES use-case;
• based on determining to activate the NES use-case, send a trigger to activate the NES use-case;
• and
• receive a first notification indicating a change in a state of the NES use-case.

At least one non-transitory computer-readable recording medium having recorded thereon instructions executable to implement a method comprising:

• receiving, by a Service Management and Orchestration (SMO) of an Open Radio Access Network (O-RAN), network energy saving (NES) information from at least one of an O-RAN Distributed Unit (O-DU) and an O-RAN Centralized Unit (O-CU), wherein the NES information includes capability exposing information received from an O-RAN Radio Unit (O-RU);
• determining, by the SMO based at least in part on the NES information, whether to activate an NES use-case;
• based on determining to activate the NES use-case, sending, by the SMO, a trigger to activate the NES use-case;
• and
• receiving, by the SMO, a first notification indicating a change in a state of the NES use-case.
