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...
Over recent years, the explosion of radio access technologies and wireless networking devices has triggered the intensive use of nomadic computing. Mobile devices receive intermittent network access, and alternate between connected and disconnected states. However, today's personal gadgets have more networking capabilities, wireless network coverage is becoming ubiquitous, and always-on IP-based services...
The paper summarizes and proofs that existing VoIP programs are powerful and flexible enough to build complex applications. The applications are independent and can be used either stand-alone or within carrier-grade Telco environments. The described example of building a call center application (outbound calling) shows the power that lies not only in existing open-source Session Initiation Protocol...
This article presents our framework intended for measurement of the Ethernet traffic, its evaluation and finally graphical representation. Whole project consists of three main parts network measurement, trace analysis and user interface.
E-learning has brought a new approach into the learning. E-learning is mainly based on the self-learning and consultations with the lector. This article presents the set of new e-learning courses and certification exams oriented at the ICT areas. The description of the courses will be given and the arrangement of the courses will be described. The different kinds of questions for the certification...
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...
