At this time, telecommunication networks are present everywhere. These networks are not only rather complex, but they are also made up of different components. That is the reason telecommunication network management (TNM) is so relevant. This paper deals with two important aspects of telecommunication network management: managed objects and expert system rules. Definition of objects is based on...

The rise of digital platforms is changing organizations, markets and the logic of innovation in the digital economy. In particular, telecommunication companies re-structure their business models to gain control of innovative services and digital platforms. In this light, we aim to advance research on digital platform business models conducting a frameworkbased case study analysis of telecommuni...

To fulfill the future demand for high data rate, novel research has been carried out which provides high-performance and secured communication from optical line terminal (OLT) to network unit (ONU). Results have incorporated with simulations in simulation software called Opti-system. Gain power estimation considered long reach using wavelength division multiplexing passive (WDM-PON). This metho...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

The forthcoming era of 3 generation (3G) mobile communications is heralded to change the wireless telecommunication experience dramatically. User expectations are raised to a significantly higher level, towards the demand for terminal-, networkand location-aware provision of ubiquitous, personalized multimedia services. Under this perspective, the need for adaptability of services and systems t...

T paper presents a biobjective genetic algorithm (GA) to design reliable two-node connected telecommunication networks. Because the exact calculation of the reliability of a network is NP-hard, network designers have been reluctant to use network reliability as a design criterion; however, it is clearly an important aspect. Herein, three methods of reliability assessment are developed: an exact...

In this paper the project MobilTel is presented. The communication itself is becoming a multimodal interactive process. The MobilTel project provides research and development activities in multimodal interfaces area. The result is a functional architecture for mobile multimodal telecommunication system running on handheld device. The MobilTel communicator is a multimodal Slovak speech and graph...

The capacity of the global communications network is being progressively increased to handle the rapid growth in telecommunication traffic generated by the Internet. Fujitsu supplies submarine optical cable systems that can provide the huge capacity and short transmission delay required by carriers. There are two ways to increase capacity: construct a new submarine cable system or upgrade the e...

Mobile communication systems produce gigabytes of mobility information day-to-day on country level, which could be exploited in various Intelligent Transportation System (ITS) applications. This paper presents the basic concept for tracking users based on handover (HO) zone detections provided by the telecommunication network. This concept is able to provide essential information for transporta...

Both HAPS and satellite as stand alone systems represent a flexible infrastructure to provide telecommunication capabilities for a broad set of services. Nevertheless, each of the two technologies can greatly help the other to reduce the impact of some intrinsic limitation in performance. For example, the use of HAPS as intermediate point of access can greatly reduce physical layer requirements...
