Personal video recording (PVR) is service which user knows time ago previously mainly with video cassette recorder and later with DVD recorders. Actually this service has been adapted by Telco services providers and included to their IPTV offers (IP based television). Several basic or advance scenarios and implementation are supported by existing or actually standardized NGN based IPTV solutions (e...
This paper describes the integration of the presence management service into existing IP Multimedia Subsystem (IMS) laboratory infrastructures. Both laboratories - NGNlab in Bratislava and the laboratory in Leipzig - use the Fraunhofer OpenIMS as core components for their testing IMS environment (i.e. Call Session Control Functions (CSCF), Home Subscriber Server (HSS)). The virtualization of these...
This paper describes the general concept of combinational/blended services for IP-based Television (IPTV) services in next generation networks towards its service oriented architecture concept (SOA). Besides introducing general approaches of service reusability (SOA concepts), the service enables (e.g. presence, notification, messaging) as application service function in next generation networks will...
The telecommunication community, industry and also standardization bodies like ETSI TISPAN or ITU-T are actually working on the evolution of next generation network (NGN) architecture to enable providing of IPTV services over same NGN infrastructure. We will briefly present the current standardization efforts in ETSI TISPAN to standardize IPTV platforms and summary of relevant specification. We provide...
This article presents an architecture to support IPTV services in an IMS-based NGN. The architecture extends the current IMS specification with the required functionality to meet additional requirements of IPTV services. The proposed architecture can be deployed by an IPTV provider over heterogeneous access networks (mobile, wireless, and fixed) as a part of standardized NGN solutions. After presenting...
There is a visible evolution in the telecommunication networks from pure voice traffic to the service provisioning. In this article, we focus on the evolution of the service provisioning platforms, from the Intelligent Networks towards the IP Multimedia Subsystem as the Next Generation Networks implementation. We stress the latest progress in the standardization activities, like common IMS and multimedia...
The evolution of IPTV in NGN laboratory towards the converged networks based on IP Multimedia Subsystem (IMS) is presented in the article. This article presents Broadcast TV service with trick play mode and nPVR service as a part of IMS based IPTV services with brief presentation of touched functional entities and reference points supplemented with signaling flows. As a future way of this service...
The evolution strategy of NGN laboratory towards the converged networks based on IP Multimedia Subsystem (IMS) as trends and aims for implementation of converged NGN network is presented in the article. This article describes actual implementation of NGN laboratory and future planned extensions and integration work for incorporating IMS core elements to our laboratory as unified service control subsystem...
