Traditionally OSS (Operations Support System) and BSS (Business Support System) are logical entities that represent a management system for telecom and networks. It comprises multiple functional blocks that support system includes: Network operations, provisioning, account system, service management system, customer service system.

OSS and BSS have always been essential software tools for the telecom industry, but as networks converge on IP, and business relationships and standards change, there is more emphasis on OSS and BSS than ever before. For the new telecom era the operator needs an OSS/BSS´ systems requirement, with new service layer architecture and customer experience management at the core, causing a move to a network as a service where the operator can offer user experience and customized solutions.

The need for more agile, flexible telecommunications network and set of on-demand support network services has given rise to NFV. The reality of SDN and NFV deployment is that they depend on a layer of orchestration and coordination that connects the ordering and business processes to how the network and associated services need to be configured to meet end-user and application demands.

The driving of this orchestration is OSS and BSS system that should provide an essential business functions and applications such as operations support and billing. As SDN and NFV are transforming traditional networks into software programmable network running on simplified, driving the convergence of IT and Telecoms, the OSS/BSS become of the key or enabler for supporting this new network.

Today’s OSS/BSS architectures are built on a solid but aging foundation, developed over several decades, for telecom services that were relatively static and predictable. OSS/BSS systems are undergoing significant changes in order to benefit from, and keep up with, the pace of innovation ushered in by SDN and NFV. Operators seeking to take advantage of SDN/NFV to optimize their networks and improve agility can only do so when a new generation of OSS/BSS processes is enhanced to face the new virtualized world.

The two main goals for transforming network operations are:

  Support de Network as a Service. This means network operators’ BSS and OSS could respond automatically to service and resource require for the client. Current OSS/BSS´s retain a strong “workflow” orientation that comes from their history of supporting human processes — the very processes that efficient operations have to swap out for network service automation.

Launching new services so quicky as the market demand. Since IP convergence, competition has forced operators to introduce new services faster than operators could modernize the basic design of OSS/BSS systems. It mean that would be necessary flexible operations tools for many of their new services, including database in order to gain agility and efficiency.

In the network of the future, the “services” of the network involve the dynamic composition of “experiences” from a combination of transport/connection resources, content and processing resources, subscriber knowledge and even current customer behavior and location.

The OSS and BSS systems would divide in two essential elements reflecting a separation from the supply-side vision of services to the customer, or demand-side, vision. Network transport and connection elements still forms a resource pool, but that pool is organized into services and experiences through a new “service layer,” where software tools to create features and services based of software create operators’ offerings.

Operators face a changing telecom landscape. The latest advances in telecommunications technology allow operators to make their networks more reliable and secure as well as to deliver customer experiences. Most operators realize that this network transformation should be matched with a telecom-management transformation that improves their systems, processes and organizations.

OSS and BSS should enable operators to attract and retain customers and increase operational readiness for short time-to-market for new products and technologies. OSS and BSS can also reduce operational expenditures by, for example:

Tracking and tuning service performance to ensure customers have a user experience and perceive the value of the products offered.

1.- Simplifying telecom management by incorporating capabilities within each network domain. This involves utilizing a network domain manager to hide the network complexity and make the capabilities and features of each network domain available to the client. The concept one customer one segment.

2.- Moving to cost-efficient, integrated management based on flexible network architecture with clear roles.

3.- The operators should maximize their chances of success by taking a step-by-step approach to evolving their management systems and processes, supported by OSS and BSS capable to offer user experience of end-to-end telecommunication solutions.
