What is OSS/BSS in telecom?
OSS and BSS are the two families of systems that keep a telecom operator running. OSS, operations support systems, manage the network: provisioning services, monitoring performance, fixing faults. BSS, business support systems, manage the business: customers, orders, and billing.
Put simply, OSS keeps the network working and BSS keeps the money and customers flowing. When you sign up for a plan and it activates and bills correctly, both halves just cooperated behind the scenes.
Modernizing these systems is a major undertaking for any operator, because nearly every service and every bill passes through them.
Sthenos builds enterprise systems for the sector, like an enterprise digital platform for a Saudi communications infrastructure provider.
Related terms: ETL (extract, transform, load), core banking system.
What is the difference between OSS and BSS?
OSS runs the network and its operations. BSS runs the customer and revenue side, like billing and order management.
