Abstract
A cluster-based, delegated software upgrade scheme facilitates software upgrade for radio base station nodes comprising a cluster of a flat radio access telecommunications network. The plural radio base stations are grouped into clusters (30), and a master radio base station (RBSM) designated for each cluster. The master radio base station (RBSM) is used to initiate software upgrade of the radio base stations comprising the cluster. The master radio base station (RBSM) can also perform a monitoring of implementation of the software upgrade at the radio base stations of the cluster, and on the basis of the monitoring, determine whether a cluster-wide software upgrade is successful. In one of its example modes, the master radio base station can further prepare a software upgrade report which confirms/summarizes implementation of the software upgrade at the radio base stations of the cluster.
