<\/a><\/div>\nWhen discussing mobile networks, much of the focus tends to be on radio access technologies, spectrum, or core network evolution. However, two often overlooked yet critical components in the operational backbone of any telecom network are Operations Support Systems (OSS) and Business Support Systems (BSS).<\/p>\n
While not typically defined in 3GPP specifications, OSS and BSS play a vital role in keeping the network functional and the business viable.<\/p>\n
OSS is responsible for network-facing tasks such as monitoring, configuration, fault management, and performance optimisation, commonly summarised using the FCAPS model: Fault, Configuration, Accounting, Performance, and Security. It ensures the network operates smoothly and supports the delivery of services.<\/p>\n
BSS, on the other hand, deals with customer-facing functions like CRM, order handling, billing, and revenue management. It ensures that customers can purchase, use, and be billed accurately for services,\u00a0 forming the foundation for business growth and customer satisfaction.<\/p>\n
To help introduce this important topic, we\u2019ve created a short video explainer that outlines:<\/p>\n
- \n
- The basic architecture of OSS and BSS<\/li>\n
- Their roles within a multi-vendor network<\/li>\n
- Key interfaces such as EMS, NMS, and TMN<\/li>\n
- Why OSS\/BSS are critical for digital transformation and operational efficiency<\/li>\n<\/ul>\n
