System and method for cordon of O-cloud node

An apparatus for cordoning one or more Open Radio Access Network (O-RAN) Cloud (O-Cloud) nodes, the apparatus comprising:

• at least one memory storing computer-executable instructions;
• and
• at least one processor configured to execute the computer-executable instructions to:
• receive, by a Service Management and Orchestration Framework (SMO) function, a first request to cordon at least one O-Cloud node, the first request being received from a user terminal or from an rApp of a Non-Real-Time (Non-RT) RAN Intelligent Controller (RIC);
• transmit, by the SMO function to an Infrastructure Management Services (IMS) and/or Deployment Management Services (DMS) via an O2 interface, a second request to cordon the at least one O-Cloud node based on the received first request;
• and
• receive, from the IMS/DMS, a first notification that the at least one O-Cloud node has been cordoned,
• wherein the SMO function is at least one of a Federated O-Cloud Orchestration and Management (FOCOM) and Network Function Orchestration (NFO).

A non-transitory computer-readable recording medium having recorded thereon instructions executable by at least one processor to cause the at least one processor to perform a method comprising:

• receiving, by a Service Management and Orchestration Framework (SMO) function, a first request to cordon at least one O-Cloud node, the first request being received from a user terminal or from an rApp of a Non-Real-Time (Non-RT) RAN Intelligent Controller (RIC);
• transmitting, by the SMO function to an Infrastructure Management Services (IMS) and/or Deployment Management Services (DMS) via an O2 interface, a second request to cordon the at least one O-Cloud node based on the received first request;
• and
• receiving, from the IMS/DMS, a first notification that the at least one O-Cloud node has been cordoned,
• wherein the SMO function is at least one of a Federated O-Cloud Orchestration and Management (FOCOM) and Network Function Orchestration (NFO).
