Business Support System

Business Support Systems (BSS) are the components that a telephone operator or telco uses to run its business operations towards customer. BSS and OSS platforms are linked in the need to support various end to end services. Each area has its own data and service responsibilities.

Role of Business Support Systems

The role of Business Support Systems in a service provider is to cover four main areas:
*Product Management
*Customer Management
*Revenue Management
*Order Management

Product Management

Product management supports product development, the sales and management of products, offers and bundles to businesses and mass-market customers. Product Management regularly includes offering cross-product discounts, appropriate pricing and customer loyalty programmes.

Customer Management

Service Providers require a single view of the customer and regularly need to support complex hierarchies across customer-facing applications (Customer relationship management). Customer Management also covers requirements for partner management and 24x7 Web-based customer self-service. Customer Management can also be thought of a full-fledge Customer Relationship Management systems implemented to help customer care agents handle the customers in a better and informed manner.

Revenue Management

Revenue Management is a BSS focus on billing, charging and settlement, that can handle any combination of OSS services, products and offers. BSS Revenue Management supports OSS order provisioning and often partner settlement.

Order Management

Order Management as a beginning of assurance is normally associated with Operational Support Systems though Business Support Systems are often the business driver for Fulfillment Management and order provisioning.

TeleManagement Forum

Most recently the TM Forum (TMF) has developed a communications domain model that provides the basis for clarifying the distinction between OSS and BSS systems. As shown in the figure the BSS supports the more Customer Facing domains. Whereas the OSS supports the traditional Resource and Resource Facing Service domains.

In NGOSS [http://www.tmforum.org/browse.aspx?catID=2025&linkID=29276] applications provide access to system capability, which can generally be categorized as either BSS or OSS. The capability offered by an application through its deployed components can be further categorized as shown in the figure. Business activities such as Fulfillment, Assurance & Billing (see eTOM) will necessarily utilize BSS and OSS applications capability from each of the domains to support end-to-end process flows.
