Business Support Systems (BSS) are the systems that a telephone operator or Telco uses to run its business operations. The term BSS is no longer limited to telephone operators offering mobile to fixed and cable services but also can apply to service providers in all sectors such as utility providers. The two systems together are often abbreviated BSS/OSS or simply B/OSS.
Typical types of activities that count as part of BSS are taking a customer’s order, managing customer data, billing, rating, and offering B2B and B2C services.
BSS are typically based on new model called TOM (Telecoms Operations Map) or eTOM (enhanced Telecom Operations Map).
