A method of managing hardware resources in an open RAN cloud platform, a cloud platform, an open RAN application and a computer program

Abstract

A method of managing hardware resources in an Open Radio Access Network, Open RAN, cloud platform is provided. The cloud platform is configured to host an Open RAN application at a radio site. The Open RAN application comprises one or more application processes. The method comprises communicating, from a master node of the cloud platform to the Open RAN application, hardware resource status data. The hardware resource status data may comprise log data, hardware resource utilisation statistics or an alarm associated with hardware resource utilisation of an application being above a threshold. The hardware resource data may cause the RAN application to reduce its resource utilisation. The cloud platform may be a Kubernetes cloud platform comprising master nodes and worker nodes. The worker nodes host pods having RAN applications in containers. Figure 3
