This paper describes the IP Multimedia Subsystem (IMS), a Service Delivery Platform architecture for providing multimedia applications in converging fixed and mobile IP networks, called Next Generation Networks (NGN). It introduces the IMS architecture, which represents a combination of the classic Intelligent Network concept of the telecom world and current Internet protocols, and highlights t...

IP Multimedia Subsystem (IMS) is defined by 3GPP/3GPP2 and has become as a major part of the next-generation networks (NGN) service delivery platform. IMS provides convergence of two most successful communication paradigms – data networks (the Internet) and cellular networks on IP based infrastructure. Such platform allows an easy development of new value added and multimedia services. Open arc...

IP Multimedia Subsystems (IMS) is a new standard in communications defined by Third Generation Partnership Project (3GPP). It has a vision to combine two most successful technologies in communications: cellular networks and internet. Within the integration of those services defined in IMS, users will be able to use their cellular device to access all services provided in internet in an easy, ef...

In July 2006, International Telecommunication UnionTelecommunication Standardization Sector (ITU-T) Study Group 13 initiated the approval process for a batch of framework Recommendations on the Next Generation Network (NGN) Release 1. One of the new Recommendations, Y.2012, illustrates the NGN from the viewpoint of a functional architecture consisting of various functional blocks, namely functi...

The notion of next generation networks (NGN) is based on the convergence of fixed and mobile telecommunication networks and the internet towards an all-IP environment. These NGNs support the provision of integrated information and communication services in face of increasingly becoming more complex value chains, enabled by so-called service delivery platforms (SDPs). Therefore an NGN is an envi...

The Next Generation Network (NGN) architecture was proposed for delivering various multimedia services with guaranteed quality. For this reason, the elements of IP Multimedia Subsystem (IMS) concept (an important part 4G/5G/6G mobile networks) are used in its service stratum. This paper presents comprehensive research on how parameters an IMS/NGN network and traffic sources influence mean Call ...
