6.1 Introduction

Currently, dramatic changes are affecting the way we communicate. New standards for both wired and wireless communications allow increasingly higher data rates at significantly lower costs. As internet access became a commodity, feature-rich communication and multimedia services such as Voice over Internet Protocol (VoIP), multiplayer online gaming, Internet Protocol Television (IPTV), and multi-mode teleconferencing are expanding the traditional voice and messaging services. With technology miniaturization and rapid reductions in integrated circuit size, in addition to wired and wireless communication convergence, we are also witnessing the convergence of fixed and mobile wireless communications. Contrary to multiplatform systems for multiservices, IP based Multimedia Systems (IMS) offer a single platform for a multitude of services resulting in increased revenues at lower operator expense. Mobile communications are playing an increasing role in the IMS services. A...
