OSS/BSS

OSS/BSS, in telecommunications, refer to operations support system and business support system. The distinction emphasizes a separation of concerns between maintaining network operations and the business around which that network is built. Communications service providers support a broad range of services and functions with their OSS/BSS. BSS primarily consists of order capture, Customer Relationship Management and Telecommunications billing whereas OSS covers Order Management, Network Inventory Management and Network Operations.

OSS and BSS are the software, processes and data capabilities that allow network owners to operate and monetise communications services. OSS traditionally focuses on network and service operations such as assurance (fault-fix) and fulfilment (service activations), while BSS supports product management, customer engagement and revenue processes. In practice, modern platforms span both domains to enable end-to-end automation across product, service and network lifecycles.
