WiMAX integration in NGN network, architecture, protocols and services

摘要

With growing demands for fast provision of new and complex services, imposed by life and business dynamic in general, service providers are forced to adopt open technologies and advanced business models in their solutions. These enable a fast response to market demands and maximum utilization of the network. A big challenge for operators today is how to deliver broadband services in rural areas. Today, the broadband services in urban areas are served by DSL and cable modems. However, it is too difficult and very expensive for operators to deploy wired network in rural areas. BWA technology can overcome this problem. Today, the most popular BWA technology is WiMAX (commonly referred as IEEE 802.16), which supports fixed, nomadic, portable, and mobile operations. WiMAX is based on IP network. As a result, many operators around the world are interested to integrate WiMAX in existing networks to facilitate the move to an all IP.
