Classification: CPC H | IPC H

Claim 0:
1. A method for high availability (HA) management in an open radio access network (O-RAN) comprising:
given a cell site O-RAN cloud (O-Cloud) comprising multiple O-RAN radio units (O-RUs) that couple to multiple local HA managers respectively, each O-RU comprises one or more radio-frequency (RF) clusters, one or more computation clusters, and one or more interface clusters;
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.
