NGOSS-based convergent OSS framework using BPM for converged e-business environment

Recently, most wired telecom service carriers are faced to decreasing of the number of subscriber because of the expansion of wireless market and blocking of net earnings. To overcome that business environment, telecom service carriers try to change their service infrastructure from network-focused service to value-added and customer-focused one that can create new value. Such changes will ultimately bring forth a service and network convergence. This also entails paradigm shift in operational management and now most service carriers are rushing to build a new converged Operational Supporting System (OSS) to efficiently accommodate the network evolution. To cope with this new business environment, KT had driven NeOSS (New OSS) [1] project, which total expense is about 1.5 billion dollar, to build convergent OSS for past 3 years. This paper proposes convergent OSS framework, NeOSS framework, complied with NGOSS (Ne
