Abstract

IP Multimedia Subsystem (IMS) is an architectural framework for delivering Internet Protocol (IP) multimedia services. The main beautiful feature of the IMS is convergence of fixed and wireless networks to provide voice, data and variety of multimedia services. It provides the an opportunity to build open IP based service platform that will enable an easy and efficient deployment of new multimedia communication services mixing voice and data services. IMS is the best solution for any telecom operators who are providing both wired and wireless service for providing the convergence service but proper co-ordination among the different access network is must for the heterogeneity of the service. So, it is very important to know the performance of IMS in the different access networks (Wired and Wireless networks). In this paper, we analyze the signaling performance in various access networks. Basically, in this paper we compare the session setup time and release time between two end user equipments (UEs) having same access networks with same access technology and having different access networks with different access technologies through IMS network.
