O-cloud node shutdown management
View Patent ↗Provided are a method, system, and device for shutting down an identified Open Radio Access Network (O-RAN) Cloud (O-Cloud) node. The method may include: receiving, by a Federated O-Cloud Orchestration and Management (FOCOM), a recommendation from an rApp to shutdown an identified O-Cloud node; sending, by the FOCOM, an instruction to a Network Function Orchestrator (NFO) to relocate a workload from the identified O-Cloud node to alternative O-Cloud node based on the recommendation; and sending, by the FOCOM, an instruction to Infrastructure Management Services (IMS) to shutdown the identified O-Cloud node.
1 . A method comprising:
receiving, by a Federated O-Cloud Orchestration and Management (FOCOM), a recommendation from an rApp to shutdown an identified O-Cloud node;
sending, by the FOCOM, an instruction to a Network Function Orchestrator (NFO) to relocate a workload from the identified O-Cloud node to alternative O-Cloud node based on the recommendation; and
sending, by the FOCOM, an instruction to Infrastructure Management Services (IMS) to shutdown the identified O-Cloud node.
2 . The method as claimed in claim 1 , wherein the rApp is subscribed to O1 related data from Operations, Administration, Maintenance (OAM) and O2 related data from the FOCOM.
3 . The method as claimed in claim 2 , wherein the rApp uses a machine learning model based on collected data from the O1 related data and the O2 related data to generate the recommendation, and wherein the O1 related data and the O2 related data are related to traffic patterns and resource usage.
4 . The method as claimed in claim 1 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to check the availability of the alternative O-Cloud node, wherein:
if the NFO is able to find an alternative O-Cloud node, the NFO is configured to send an instruction to a Deployment Management Service (DMS) to migrate the workload; and
if the NFO is unable to find an alternative O-Cloud node, the NFO is instead configured to send an error message to the FOCOM.
5 . The method as claimed in claim 4 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to send an instruction to Operations, Administration, Maintenance (OAM) to drain traffic from the identified O-Cloud node.
6 . The method as claimed in claim 5 , wherein the instruction to the IMS to shutdown the identified O-Cloud node is sent upon receiving confirmation from the NFO that the DMS has migrated the workload.
7 . The method as claimed in claim 1 , wherein the rApp, the FOCOM, and the NFO are each in communication with Service Management and Exposure (SME) and Data Management and Exposure (DME) to receive information related to at least one of services, endpoints, and supported data types.
8 . A system comprising:
a memory storing instructions; and
at least one processor configured to execute the instructions to implement a Federated O-Cloud Orchestration and Management (FOCOM) configured to:
receive a recommendation from an rApp to shutdown an identified O-Cloud node;
send an instruction to a Network Function Orchestrator (NFO) to relocate a workload from the identified O-Cloud node to alternative O-Cloud node based on the recommendation; and
send an instruction to Infrastructure Management Services (IMS) to shutdown the identified O-Cloud node.
9 . The system as claimed in claim 8 , wherein the rApp is subscribed to O1 related data from Operations, Administration, Maintenance (OAM) and O2 related data from the FOCOM.
10 . The system as claimed in claim 9 , wherein the rApp uses a machine learning model based on collected data from the O1 related data and the O2 related data to generate the recommendation, and wherein the O1 related data and the O2 related data are related to traffic patterns and resource usage.
11 . The system as claimed in claim 8 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to check the availability of the alternative O-Cloud node, wherein:
if the NFO is able to find an alternative O-Cloud node, the NFO is configured to send an instruction to a Deployment Management Service (DMS) to migrate the workload; and
if the NFO is unable to find an alternative O-Cloud node, the NFO is instead configured to send an error message to the FOCOM.
12 . The system as claimed in claim 11 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to send an instruction to Operations, Administration, Maintenance (OAM) to drain traffic from the identified O-Cloud node.
13 . The system as claimed in claim 12 , wherein the instruction to the IMS to shutdown the identified O-Cloud node is sent upon receiving confirmation from the NFO that the DMS has migrated the workload.
14 . The system as claimed in claim 8 , wherein the rApp, the FOCOM, and the NFO are each in communication with Service Management and Exposure (SME) and Data Management and Exposure (DME) to receive information related to at least one of services, endpoints, and supported data types.
15 . A non-transitory computer-readable recording medium having recorded thereon instructions to perform a method comprising: receiving, by a Federated O-Cloud Orchestration and Management (FOCOM), a recommendation from an rApp to shutdown an identified O-Cloud node;
sending, by the FOCOM, an instruction to a Network Function Orchestrator (NFO) to relocate a workload from the identified O-Cloud node to alternative O-Cloud node based on the recommendation; and
sending, by the FOCOM, an instruction to Infrastructure Management Services (IMS) to shutdown the identified O-Cloud node.
16 . The non-transitory computer-readable recording medium as claimed in claim 15 , wherein the rApp is subscribed to O1 related data from Operations, Administration, Maintenance (OAM) and O2 related data from the FOCOM.
17 . The non-transitory computer-readable recording medium as claimed in claim 16 , wherein the rApp uses a machine learning model based on collected data from the O1 related data and the O2 related data to generate the recommendation, and wherein the O1 related data and the O2 related data are related to traffic patterns and resource usage.
18 . The non-transitory computer-readable recording medium as claimed in claim 15 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to check the availability of the alternative O-Cloud node, wherein:
if the NFO is able to find an alternative O-Cloud node, the NFO is configured to send an instruction to a Deployment Management Service (DMS) to migrate the workload; and
if the NFO is unable to find an alternative O-Cloud node, the NFO is instead configured to send an error message to the FOCOM.
19 . The non-transitory computer-readable recording medium as claimed in claim 18 , wherein upon receiving the instruction from the FOCOM to relocate the workload, the NFO is configured to send an instruction to Operations, Administration, Maintenance (OAM) to drain traffic from the identified O-Cloud node.
20 . The non-transitory computer-readable recording medium as claimed in claim 19 , wherein the instruction to the IMS to shutdown the identified O-Cloud node is sent upon receiving confirmation from the NFO that the DMS has migrated the workload.
