Nowadays, with the development of next generation networks, new standards for voice and video services have been introduced, and VoIP (Voice over IP) has become a very popular protocol. It leads to the convergence of networks which provide voice and data transfer services with enhanced and improved applications for customers. As a key element of the next generation networks, IMS (IP Multimedia Subsystem) architecture aims to offer multimedia services via fixed-mobile convergent solutions. In this paper, a work model offering triple play services via a UMTS network and an IMS subsystem is realized.
