Abstract :
By the introduction of the concept of Next Generation Networks (NGN), the management of these networks has become an important issue. So, the requirements, goals and the overall architecture of NGN management systems are discussed in this paper. The functional classification of Operation Support Systems (OSS) used in NGN management is also presented. Because of the need of utility networks (such as telephony, data, water, electricity and gas) in the country to OSS, the amount of required capital investment for deployment of Network Management System (NMS) and Customer Care and Billing System (CCBS), as main parts of OSS, are calculated for the next four years in this paper. To reach these estimates, the total number of subscribers in mentioned networks is forecasted for this period and information about per customer capita is also extracted. Two frameworks of, distributed and centralized, are considered. This assessment shows an approximate investment of M606$ and M432$ is needed for NMS and CCBS in distributed scenario, respectively. The same requirement in centralized scenario is M433$ and M322$ for NMS and CCBS, respectively. So, an approximate investment of M1040$ and M750$ is needed for OSS in distributed and centralized scenarios, respectively.
