Abstract
Systems, methods, and software for implementing a software upgrade in a virtualized Offline Charging System (OFCS) that includes a pool of Virtualized Charging Collection Functions (vCCF). In one embodiment, a software upgrade is identified for the virtualized OFCS, and installed with an upgrade process. The upgrade process includes developing a skeletal vCCF, which is pre-provisioned in the network, and installing the software upgrade in the skeletal vCCF. The upgrade process includes communicating with a DNS server to modify the priority in a DNS resource record for the skeletal vCCF to equal at least one of the other vCCFs in the pool. The upgrade process also includes designating an antiquated vCCF in the pool as the (next) skeletal vCCF, draining the accounting sessions from the skeletal vCCF, and communicating with the DNS server to set a priority in the DNS resource record for the skeletal vCCF so that the skeletal vCCF is selected last among the vCCFs in the pool by the CTFs for accounting sessions.
