Operations support systems (also called operational support systems or OSS) are computer systems used by telecommunications service providers. The term OSS most frequently describes “network systems” dealing with the telecom network itself, supporting processes such as maintaining network inventory, provisioning services, configuring network components, and managing faults.
A lot of the work on OSS has been centered on defining its architecture. Put simply, there are four key elements of OSS:
Processes-the sequence of events
Data-the information that is acted upon
Applications-the components that implement processes to manage data
Technology-how we implement the applications
Business support systems (BSS) are the components that a telephone operator or telco uses to run its business operations towards customer.
Basically it deals with the taking of orders, payment issues, revenues etc. The role of business support systems in a service provider is to cover four main areas:
- Product management
- Order management
- Revenue management
- Customer management
