QoS Analysis in IMS Network

摘要

While requirements of telecommunication services users are changing and technologies are developing, a convergence of different networks is recently noticed. Consumers want to get multimedia services on real time and at any accessible device - phone, computer or other device. These needs are already satisfied the latest telecommunications technology - the IP multimedia subsystem IMS. IMS is basically a network architecture consisting of an IP-based core network connected to multiple access networks to provide a converged service to wired and wireless subscribers [1]. By courtesy of a flexible architecture, the IMS allows easily develop the existing networks - new services are being introduced simply and quickly by reducing their development and operation costs, using packet transmission in the transport layer.
