The IP Multimedia Subsystem (IMS) is a control architecture framework for the Next Generation Network (NGN). It is expected that this new network architecture will provide a new kind of IP multimedia services delivered in network converged environments. The NGN and IMS, even after the years of a standardization effort, are still hot networking topics. One of the communities, which adopt emerging communications standards into their products fast, is the open source community. In present days, there are a few open source products, which allow building the IMS environment. However, there are at least two domains for which they are especially helpful. It is teaching/learning of the IMS architecture and testing service eployment in a nearly real environment. This article provides a survey of available open source products. It also describes the experience with the implementation, establishment and running an IMS testbed, which has been built up on an open source client and server entities. At the server side, the focus is on the Kamailio IMS platform.

Communications - Scientific Letters of the University of Zilina 2011, 13(2):59-63 | DOI: 10.26552/com.C.2011.2.59-63

The management of crisis situations is undergoing rapid changes due to advances of Information Technology. We discuss the role of information systems in supporting decision making processes in crisis management. The crisis management poses particular challenges for information systems - it is characterized by dynamic, complex environments involving many actors in often very unique and extreme situations. We review the roles, benefits and challenges of information systems' application to different phases of the crisis management. We argue that for the different phases of the crisis management, the different types of information systems varying in the aspects such as use scenarios, user requirements, critical technologies, etc. are suitable. Finally, we outline the directions for future research and applications for the field of the support systems for the emergency management.

The Challenges of Market Research in China

Lena Weick

Communications - Scientific Letters of the University of Zilina 2009, 11(1):60-63 | DOI: 10.26552/com.C.2009.1.60-63

This article analyses the challenges of current market research activities in China. A country that achieved remarkable economic development since the late 1970s and that is still continuing to grow.Firstly a picture of the market research industry in China is provided. Based on the history of market research, the leading companies and the most important types and aims of research are highlighted. The development of the market research industry in the framework of the Chinese market in general leads to challenges in primary and secondary research. Primary research in China is dominated by regional disparities, particularly in terms of language and culture. A continuous trend to urbanisation leads to a massive accumulation of individuals and enterprises in 'mega cities'. Even so, the challenge of providing solid data quality seems to be still considerable. On the other hand, secondary data is still lacking in many ways. The availability is still sporadic and the quality remains inadequate. Furthermore the validity in general appears to be questionable.As discretionary income increases, the type and amount of products being consumed has changed significantly. Chinese customers are therefore confronted with a growing range of buying decisions. The rate of which the Chinese market is changing underlines the importance of research being up-to-date.

Peter Faith

Communications - Scientific Letters of the University of Zilina 2008, 10(3):33-39 | DOI: 10.26552/com.C.2008.3.33-39

The article deals with the present trends in the passenger road transport in the Slovak Republic. It provides the characteristic of indicators of development phases of the passenger road transport trends. Existing increase of number of vehicles and individual road transport performances shall bring unfavourable impacts on environment on the one hand and on the other hand, it shall be the source of the state budget income.Permanent conflict between individual road transport and mass passenger transport makes all administrative authorities to follow impacts on the life of inhabitants in agglomerations with assumed higher concentration of inhabitants. Demand for passenger cars will be permanent and any decrease in the passenger road transport cannot be assumed. Therefore, it is necessary to show a permanent interest in this sphere of problems and deal with it on the highest possible level.

Standardization Paths for NGN IMS-Based Architecture

Tatiana Kovacikova, Pavol Segec, Michal Bruncko

Communications - Scientific Letters of the University of Zilina 2008, 10(4):15-18 | DOI: 10.26552/com.C.2008.4.15-18

Thanks to the rapid development of technology and increased availability of bandwidth, today more than ever, multiple services such as voice, video and data can be integrated and efficiently carried over a single infrastructure based on a packet network. An NGN (Next Generation Network) is able to deploy those services independently from underlying transport-related technologies, giving fixed or mobile users an access to different providers with the adequate QoS and security. In fact, it is the IMS (IP Multimedia Subsystem) inside the NGN that enables and drives efficient converged service offerings. IMS provides the framework for a common service and session control layer standardized on IP, with SIP controlling all media sessions. The IMS standardization breaks down all the functions necessary to support multimedia applications and to provide standardized (open) interfaces towards application servers enabling enhanced premium services as well as the interworking with other (legacy) networks such as the PSTN/PLMN (Public Switched Telephone Network/Public Land Mobile Network. The paper is describing the current state of the art in the NGN standardization within the ETSI and related standardization bodies.

Communications - Scientific Letters of the University of Zilina 2008, 10(1):45-48 | DOI: 10.26552/com.C.2008.1.45-48

The project management includes acomplicated complex of activities. An important component of these activities is technical use of software for the support of project management and the management of the object, service (or their combination), which are outputs of the project. The important group of the activities creates the management of the cost with the accent on complex project efficiency. The next activities are connected with the management of the processes in the time, their coordination and their following communication among various participants of the project. There are many specialized activities in the life-cycle of the project, and for this reason the project manager must have abroad and complex area of special knowledge. He should improve not only in the area of his competences and skills but also in the area in which he works (in various economic areas or in the security area).

Critical Infrastructure Risks

Michail Senovsky, Pavel Senovsky

Communications - Scientific Letters of the University of Zilina 2008, 10(1):54-59 | DOI: 10.26552/com.C.2008.1.54-59

Critical infrastructure can be taken as aphenomenon of recent time. Not only theory but also practice has shown that solving problems of the protection of critical infrastructure, especially ensuring its functionality, is a necessary precondition for the operation of public authorities, services, the viability of aregion, area or country. The first step to protect the critical infrastructure must be the identification of risks endangering the security of single systems or elements. The contribution deals with the problems of searching for and denoting these risks and by looking for their interrelations.

Transport Policy Related to Road Transport and Sustainable Development

Jozef Gnap, Vladimir Konecny

Communications - Scientific Letters of the University of Zilina 2003, 5(1):52-61 | DOI: 10.26552/com.C.2003.1.52-61

Development in almost all sectors of economy will immediately affect the transport sector. We can say that growth in economy leads automatically to growth in road transport. As a continuous process the road transport industry produces vehicles by new technologies and transport operators finance this section by purchasing new trucks and coaches. There is a continual and tightened process in the road transport legislation, the EU has elaborated conceptions for achieving sustainable development. The state transport policy of the Slovak Republic has to reflect specified results and conceptions, otherwise road transport in the Slovak Republic becomes the brake of sustainable development.

An Impact of Improvement-Exchange Heuristics to Quality of Probabilistic TSP Solution

Jaroslav Janacek, Juraj Hurtik

Communications - Scientific Letters of the University of Zilina 2003, 5(4):27-35 | DOI: 10.26552/com.C.2003.4.27-35

This paper deals with a probabilistic travelling salesman problem (PTSP), which differs from a travelling salesman problem (TSP) [6] in the demand for a customer visit. In PTSP is each customer visited with a given probability only. An objective function for PTSP is in general hard to enumerate and it is even harder to estimate an influence of a local change of a PTSP solution on the final value of the objective function of the resulting solution. This hardiness complicates construction of an efficient heuristic for this problem. In this contribution we have focused on research of a relation between type of local change operation and the resulting objective function improvement. We have constrained here ourselves to improvement-exchange heuristics only, whereas inserting heuristics were broadly studied in the previous works [3], [5]. In this work we have tried to suggest several types of feasible solution changes (operations) including estimation of their impact on the objective function value. These operations have been embedded into the best admissible strategy and implemented as a part of software system, which enables exact or approximate evaluation of a PTSP route depending on the problem size. Using this system we have performed a sequence of numerical experiments to reveal relation between complexity of the used heuristics operations and final improvement of the resulting objective function value. This numerical result and associated conclusions are reported in the concluding part of this contribution.
