Classification: CPC H | IPC H

Claim 14:
15. A non-transitory computer-readable medium or media comprising one or more sequences of instructions which, when executed by one or more processors, causes steps to be performed comprising:
given a cell site open radio access network cloud (O-Cloud) comprising multiple O-RAN radio units (O-RUs) with each O-RUs coupled to a corresponding local high availability (HA) manager respectively, each O-RU comprising one or more radio-frequency (RF) clusters, one or more computation clusters, and one or more interface clusters, performing HA management for the cell site O-Cloud using steps comprising:
instantiating one or more O-RU instances, with redundancy, on the cell site O-Cloud to serve one or more users, the one or more O-RU instances involve one or more O-RUs among the multiple O-RUs, each O-RU instance comprises at least one RF cluster handling RF front end, at least one computation cluster handling digital front end (DFE) and low PHY, and at least one interface cluster handling fronthaul transport to/from an O-RAN distributed unit (O-DU);
monitoring, using the local HA manager for each of the one or more O-RU instances, instance performance of the one or more O-RU instances for failure prediction/detection; and
in response to a failure for one or more O-RU instances being detected or predicted, instantiating one or more new O-RU instances in the same O-RU with detected or predicted O-RU instance failure or in another O-RU within the cell site O-Cloud.
