NGN platform should be able to provide the capabilities (infrastructure, protocols, etc.), so that it should be possible to develop, deploy/implement and manage all types of services (known and expected) [1], [12]. This involve the possibility to apply different types of media (audio, video, text, data), different types of encoding techniques, data services, conversation services, user and group transmission services, messaging services, real-time and Non-real time Conversational Voice services, data communication services, delay sensitive services, delay non sensitive services, etc. These types of services required the different speed of communication connection (from some kbps till hundreds of Mbps), which are required for the given service. These requirements have to be supported by the capabilities of the transport technologies.
One of the expected advantages of the NGN platform is the user comfortable and flexible access and control of multimedia services. At some time the NGN should provide the effective interface for service development, service providing and service management.
