In 21st century, the development strategy and the management policy of Information Communication Technology (ICT) is a key issue to a nation¡¦s competitiveness. Particularly, the development of telecommunication liberalization, governance in the telecommunications regime and the relevant science and technology policies of the telecommunication industry is the most important factor for creating a leading knowledge-based economy for Information Communication Technology related industries.
Looking forward to the future, the trends and developments of the convergence of telecommunication, broadcasting and internet services will drive the demand for the telecommunication and broadcasting industries to look for cost-efficient provisioning of converged multimedia services. The emerging technology of next generation network (NGN) infrastructure enables the convergence of multi-access networks to deliver the multimedia contents and application services seamlessly. Therefore, the consumers, government, and industry can obtain the benefits because of technology development and industrial cooperation.
In addition, the converged broadcasting and telecommunication services as well as Fixed-Mobile Converged applications over the internets results in the needs for the improvement in network interconnectivity and service interoperability. No matter it is telecommunication, broadcasting or information, to converge as common info-communication services, such as telephony, data and multimedia will eventually run over the all IP networks. Therefore, IP Multimedia Subsystem (IMS) becomes one of the promising technologies to drive it happen. However, existing policy and regulations must cope with the changes of this development. The liberalization of broadband and communication market allows the participation of the private companies to create new investment and revenue.
This research studies the possible evolution of an IP-based communication infrastructure from today's networks toward a converged next generation network and proposes an Inter-Exchange Center of Converged Network Architecture (IEXCNA), applying to VoIP service. The IEXCNA model shows more efficient in the transmission, interconnectivity and reducing implementation cost of network infrastructure. Thus the consumers are able to enjoy better quality of service and cheaper rate of use for multimedia services.
