Abstract :
IP multimedia subsystem (IMS) realizes the convergence of fixed and mobile networks. In virtue of providing various types of multimedia services among different kinds of access networks, IMS is considered as the core network for future Next Generation Networks. For detecting the requested services quickly and efficiently, it is necessary for IMS to adopt a valid Service Discovery function. In this paper, we propose an optimal model of Service Discovery Architecture based on IMS to support a universal Service Discovery function independent of any specific network access technology. The optimal model analyses are studied by mathematical modeling, theoretical analyses, and numerical simulations.
