Model-based service discovery — prototyping experience of an OSS scenario

The practical success of the next generation operation support systems (OSS) relies largely on its flexibility in providing adaptive and cost-effective services. Service discovery is an essential mechanism to achieve this goal. Driven primarily by the OSS requirements, this paper proposes a new service discovery methodology for next generation OSS — model-based service discovery (MBSD). MBSD takes advantage of the OMG MDA (model-driven architecture) technology. The system architecture of MBSD and its operation and implementation are presented. The proposed methodology is briefly validated through an OSS scenario.     

The potential for open source software in telecommunications operational support systems

Over the last five years, open source software has moved into mainstream areas such as Internet and financial applications, with software such as Linux and Apache Web Server now supporting mission-critical operations. Open source software can offer both cost reductions and improvements in software quality. However, the uptake by incumbent telecommunications providers has been virtually zero, instead focusing on major commercial-off-the-shelf (COTS) packages, due to a mixture of prior strategic investments and perceptions over open source risks. This paper addresses the scope for use of open source software in telecommunications operational support systems (OSS). Firstly, the technical scope for open source software is addressed, covering the maturity of available open source software components, and the ways in which these components can have an impact on OSS software architecture. Secondly, the commercial aspects are presented, covering benefits, commercial models and risks. An OSS life cost comparison of open source versus COTS software is included. Thirdly, a test OSS created by BT using primarily open source software, combined with OSS standards to provide a minimum cost base, is presented and analysed. The paper concludes with a statement on the potential for the use of open source software in OSS, and suggests possible next steps.     

Strategic changes and frameworks affecting future OSS/BSS in the telecommunications industry

This paper highlights the changes taking place in BT’s OSS/BSS space as the company moves away from legacy IT systems towards a transformational architecture. Increasingly telecommunications system estate is very complex supporting many systems. This leads to a high cost overhead, which is at variance with new technologies, such as VoIP, which will result in diminishing basic call revenues. Equally there are requirements for increased responsiveness to change, i.e. agility, which calls for a reduction in complexity and a maximisation of reuse. Frameworks are examined such as BT’s matrix architecture, the TMF eTOM, and the value chain, together with data repositories such as SALSA which provide the underpinning required to understand and manage the challenge of reducing IT complexity.

OSS opportunities in open source software — CRM and OSS standards

In many industry verticals, open source software is proving to be a credible alternative to proprietary software. When compared to proprietary software, open source software can offer a number of benefits such as stronger customer involvement, lower costs and better quality. Despite these benefits, the take-up of open source software by incumbent telecommunications providers has been virtually zero, choosing instead to focus on major proprietary commercial-off-theshelf (COTS) packages due to prior strategic investments and negative preconceptions about open source software. Although an immediate change in take-up is not expected, the pressure to reduce operational support systems (OSS) costs is steering telecommunications providers to research potential opportunities for using open source software within their OSS. This paper addresses some of those opportunities. The general opportunities are presented using specific examples from current research. Potential short-term opportunities, using readily available open source customer relationship management (CRM) applications, and potential mid-to long-term opportunities, using open source OSS integration software, are analysed and evaluated. The paper concludes with a recommendation on what telecommunications providers should do to further investigate the opportunities presented by open source OSS.
