Service Oriented Telecom Architectures for Enabling Innovative Mobile Services

Abstract

Future networks are characterized by convergence at different technological and service levels. Convergence of fixed and mobile network is a trend that is used to develop service oriented communication networks. This paper discusses service oriented telecom architecture for convergent networking and enablement of new innovative mobile services. Analysis of different existing migration strategies for service orientation results in a near similar IP-Multimedia Subsystem (IMS)-based architecture for the case of developing countries. The main migration and networking guidance parameters used are: capital and operational cost reduction, simplicity of introducing & managing new mobile services, unified pricing & billing for revenue generation, smooth migration of legacy network, and adherence to international telecom standards.
