A method for optimizing the scheduling of an O-Cloud node, the method includes: determining a NF hosted on a O-Cloud node to be migrated to another O-Cloud nodes; sending a recommendation to the SMO to migrate the determined NF; sending instructions to implement the migration of the NF via an O2 interface to an O-Cloud management service; controlling the implementation of the migration of the determined NF to the other O-Cloud nodes; upon implementation of the migration, sending a confirmation notice to the SMO via the O2 interface; wherein the determining the one or more network functions NFs to be migrated, includes: obtaining data referring to historical and/or current utilization patterns of a O-Cloud node and/or a NF hosted thereon; inputting the data to an AI/ML model; obtaining a prediction of a utilization scenario; and determining a migration recommendation for the NF.
