Vendor OSS Platforms

Ericsson Network Manager (ENM) is the primary OSS for managing Ericsson RAN, providing bulk CM (Configuration Management), PM (Performance Management), FM (Fault Management), and software management. Nokia NetAct serves the same role for Nokia AirScale base stations. Samsung Element Management System handles Samsung vRAN deployments. Each platform has its own CLI, GUI, and API interfaces for configuration changes. RAN engineers spend significant time in these OSS platforms executing bulk parameter changes, running consistency audits, and scheduling software upgrade campaigns.
