Interconnection In the Convergence Era (IP-BASED Interconnection Regulation Challenges)

The IP age of networks and services is increasing very quickly. Starting from its VoIP, NGN, and IMS to today's IP services landscape, which includes fixed and mobile high-definition (HD) voice, HD video calling, unified communications (UC), video conferencing, and telepresence, cooperation, instant messaging (IM), and the rich communication suite (RCS). Convergence is one of the most significant current trends in the ICT sector. It has changed the way services are delivered and obscured the distinction between fixed and mobile services. The transition to Next-Generation Networks (NGN) is the most important next phase in the ICT sector's convergence-driven evolution. In the realms of NGN, VoIP, and IMS, there is no PSTN equivalent; instead, there are "IP islands " that locate the total value of an IP service. The next basic step is to expand the arrive of those services across a totally interconnected cross-network premise in order to maximize their overall esteem among their target audiences. The liberalization of infrastructure services depends on managing the interconnection interface between the competitive and regulated sectors. These paper outlines regulation issues raised by IP-based interconnection and examine the current practices and procedural ways that being developed to address these concerns.

Cloud-Nutzung in der Industrie 4.0

Nachdem sich die Nutzung von Cloud-Technologien in administrativen Bereichen von Unternehmen (z. B. Office-Software, Dokumentenmanagement, Unified Communications) inzwischen etabliert hat, drängen diese verstärkt in die Realität der industriellen Fertigung vor. Um bei deren Einführung möglichst methodisch und effizient vorgehen zu können, zeigt der Beitrag anhand eines Sechs-Dimensionen-Modells entsprechende Handlungsfelder und Risikofaktoren auf, die den Erfolg von Implementierungsprojekten unterstützen bzw. beeinflussen.

An Augmented Infocommunication Model for Unified Communications in Situational Contexts of Collaboration

Aim/Purpose: In this work, the authors propose an augmented model for human-centered Unified Communications & Collaboration (UC&C) product design and evaluation, which is supported by previous theoretical work. Background: Although the goal of implementing UC&C in an organization is to promote and mediate group dynamics, increasing overall productivity and collaboration; it does not seem to provide a solution for effective communication. It is clear that there is still a lack of consideration for human communication processes in the development of such products. Methodology: This paper is sustained by existing research to propose and test the application of an augmented model capable of supporting the design, development and evaluation of UC&C services that can be driven by the human communication process. To test the application of the augmented model in UC&C service development, a proof-of-concept mobile prototype was elaborated upon and evaluated, making use of User Experience (UX) and user-centred methods and techniques. A total of nine testing sessions were carried out in an organizational communication setup and recorded with eye tracking technology. Contribution: The authors argue that UC&C services should look at the user’s (human) natural processes to improve effective infocommunication and thus enhance collaboration. Authors believe this augmented version of the model will pave the way improving the research and development of useful and practical infocommunication products, capable of truly serving users’ needs. Findings: On evaluation of the prototype, qualitative data analysis uncovered structural problems in the proposed prototype which hindered the augmented model’s elements and subsequently, the user experience. Five out of eighteen identified interaction issues are highlighted in this paper to demonstrate the proposed augmented model’s validity, applied in UC&C services evaluation. Recommendations for Practitioners: Considering and respecting the user’s natural communication processes, practitioners should be able to propose and develop innovative solutions that truly enable and empower effective organizational collaboration. UC&C functionalities should be designed, taking the augmented model’s proposed elements and their pertinence in representing the human interpersonal communication phenomena into consideration, namely: Social Presence; Immediacy of Communication; Concurrency and Synchronicity. Recommendation for Researchers: This paper intends to demonstrate that the adoption and use of UTAUT technology characteristics, in conjunction with Synchronicity proposition, can be considered as a reference for human-centric design and the evaluation of UC&C systems. Impact on Society: To highlight the need to develop further research on this important topic of human collaboration mediated by technology inside organizations. Future Research: This research focused its attention on communication functionalities. However, collaboration can potentially be affected by other services that may be included in a UC&C system, such as scheduling, meetings or task management. Future research could consider employing this augmented model to evaluate such systems or proof-of-concept prototypes.

Design and Implementation of a Collaborative Communication Network for Video Conference Services

Under the current global conditions, strong emphasis is put on saving resources and reducing costs, migrating to collaborative unified communications solutions and developing open-source Web applications. The secure video-conferencing system will mainly use VoIP and WebRTC technologies to make multimedia calls, allowing end-users mobile and remote access (MRA) and therefore to facilitate communication between different networks, as well as the accessibility and the interoperability with any type of technology and device. This article will analyze the scalable implementation of the real-time communications network, providing redundancy and load balancing, therefore ensuring the high availability of the entire collaborative communications system. The call control and the dial plan are done through the Unified Call Manager software and WebRTC videoconferencing external access functionality is provided by configuring Traversal Using Relays around NAT (TURN) service across the Expressway Series server pair (Core & Edge). The ability to manage and monitor virtual meetings remains the responsibility of the open-source management tools.

Implementation of social capital as a key driver of behavioral economy formation (in ukrainian)

The article focuses on the study of theoretical and practical component, analysis of history and application of modern knowledge of the concept of "social capital" in the formation of new direction of economic science, which is a behavioral economy. The concepts of general issues, adoption of common and separate decisions are based on mutual trust and unified communications are taken into account. More important problems of the present time, such as poverty, quality of life, solidarity, consciousness of every citizen, are raised, revealing the problem of welfare not on the surface, but from the inside, analyzing the causes. Assessment and analysis of Happiness Index, interrelation and interaction between a lucky man and social capital was conducted. Such economic phenomena as economic consciousness and economic behaviour that can offer business and world politics confidently with their theories and knowledge were identified. Building and forming social capital in unlimited connections and relationships gives hope to finding ways of solving harmonious problems of economic, social and political nature, improving opportunities of rational component not only at the state level, but also at the level of each person. Studying the concept of ‘economic subject’, which is more complicated and not limited to the scope of rationality in decision-making, aggravates the extremely important need for closer definition and analysis of economic mechanisms for real human behaviour. In this aspect the behavioral economics helps us and allows understanding each person’s behaviour in different situations. All life areas of economic entities should be aimed at improving the living standards of the population, and it is impossible without public trust in the branches of government and business. The effectiveness of the modern competitive structure in the economy, using social capital, can revive the trust and confidence of each person.
