OSS and BSS are the two halves of a telecom operator's software backbone, one runs the network, the other runs the business. This guide explains what each is and why they are mentioned together.
OSS/BSS refers to the two complementary system stacks a telecom operator runs: OSS (Operations Support Systems) manages the network, provisioning, fault, performance and inventory, while BSS (Business Support Systems) manages the business, billing, CRM, orders and revenue. Together they turn a network into a commercial service.
OSS (Operations Support Systems) is the network-facing stack. It handles service provisioning and activation, network fault and performance management, and inventory of network resources. When you order a new line and it is configured on the network, and when a fault is detected and repaired, OSS is doing the work.
BSS (Business Support Systems) is the customer-facing stack. It manages subscribers and support (CRM), captures and fulfils orders, defines products and plans, and rates usage to produce bills and collect revenue. BSS owns the commercial relationship with the customer.
Historically separate, OSS and BSS increasingly need to work as one: a customer order (BSS) must trigger network provisioning (OSS), and a network fault (OSS) affects the customer and their bill (BSS). Modern operators want unified operations across both, with automation that spans the whole flow rather than stopping at the boundary.
Ops Singularity provides a single autonomous operations layer that can span both OSS and BSS estates: it detects incidents wherever they occur, maps them to business impact, and resolves them through governed Action Tickets, rather than treating network and business operations as separate silos. See telecommunications.
OSS (Operations Support Systems) manages the network, provisioning, fault, performance and inventory. BSS (Business Support Systems) manages the business, billing, CRM, orders and revenue.
Because they are the two halves of a telecom operator's software backbone and increasingly must work as one: a customer order in BSS triggers provisioning in OSS, and a network fault in OSS affects the customer and bill in BSS.
