System and method for O-Cloud node reconfiguration in a telecommunications system

A method for implementing reconfiguration procedure of one or more open cloud (O-Cloud) nodes within a O-Cloud infrastructure of an open radio access network (O-RAN), the method comprising:

• obtaining, by a federated O-Cloud orchestration and management (FOCOM) within a service management orchestration (SMO) framework, a request to reconfigure at least one O-Cloud node hosting at least one network function of the O-RAN;
• sending, by the FOCOM, a reconfiguration request for the at least one O-Cloud node to the O-Cloud infrastructure via an O2 interface to an infrastructure management services (IMS);and upon implementation of the reconfiguration, receiving, by the FOCOM, a confirmation of the reconfiguration implementation from the IMS via the O2 interface,
• wherein the method further comprises:
• determining, by the FOCOM, in which sequence the reconfiguration of the at least one O-Cloud nodes is performed, based on performance data of the at least one O-Cloud node, and
• wherein based on determining that the reconfiguration has not been successful, the FOCOM controls to configure the at least one O-Cloud node back to a configuration prior to the reconfiguration request.

A non-transitory computer-readable recording medium having recorded thereon instructions executable by at least one processor configured to perform a method for implementing reconfiguration procedure of one or more open cloud (O-Cloud) nodes within a O-Cloud infrastructure of an open radio access network (O-RAN), the method comprising:

• obtaining, by a federated O-Cloud orchestration and management (FOCOM) within a service management orchestration (SMO) framework, a request to reconfigure at least one O-Cloud node hosting at least one network function of the O-RAN;
• sending, by the FOCOM, a reconfiguration request for the at least one O-Cloud node to the O-Cloud infrastructure via an O2 interface to an infrastructure management services (IMS);and
• upon implementation of the reconfiguration, receiving, by the FOCOM, a confirmation of the reconfiguration implementation from the IMS via the O2 interface,
• wherein the method further comprises determining, by the FOCOM, in which sequence the reconfiguration of the at least one O-Cloud nodes is performed, based on performance data of the at least one O-Cloud nodes, and
• wherein based on determining that the reconfiguration has not been successful, the FOCOM controls to configure the at least one O-Cloud node back to a configuration prior to the reconfiguration request.
