Convergence has more than ever been a central issue for fixed and mobile operators throughout the world and is considered to be the next big step in the evolution of telecommunication networks. Convergence opens new market opportunities and competition among network operators and above all offers enhanced user experience. Multimode handsets and the proliferation of terminals and access technologies are generating increasing demands for solutions that enable convergence, seamless handover, and transparent service delivery across heterogeneous access networks. Different strategies are available for operators, depending on the services they intend to deliver to their customers, from basic commercial convergence limited to unified billing for Fixed/Mobile/Internet up to in-dept network convergence covering new applications and services. This article surveys different technologies which offer seamless handover and converged access to mobile voice, video, and data services. It provides first the different network parts involved in defining the operator global convergence strategy and then surveys different technologies which achieve this step-by-step convergence. We present the main features of these technologies and discuss their limitations and potentials to enable convergence in heterogeneous networks. We also provide a personal stance as to the emergence of these technologies and our vision towards the long term converged telecommunication networks. 相似文献

Competition in the telecommunications market is growing rapidly. Therefore, network operators and service providers have to reform their marketing and service delivery strategies in order to be competitive in the broadband service market. A convergence strategy for fixed and mobile services via a standards-based IN platform may provide a step in the right direction. This article deals with evolutionary steps for convergence services and their benefits to network operators and customers. It presents possible migration paths from the existing GSM to UMTS. The article also provides a comparative analysis of the wireless technologies involved in this evolution 相似文献
