The paper is devoted to the development of methods of ontology supported knowledge discovery in the field of mobile network subscribers. We develop the ontological model of the domain of mobile networks. This ontological model is intended to describe the behavior of mobile network subscribers. The ontological model is based on the four-level model of knowledge representation. In the paper, spec...

■ The mobile Internet represents a massive opportunity for mobile operators and content providers. Today there are more than 2 billion mobile subscribers, with 3 billion predicted by the end of 2007. However, despite significant improvements in handsets, infrastructure, content, and charging models, mobile users are still struggling to access and locate relevant content and services. An importa...

The number of mobile subscribers in the world is soon reaching the three billion mark.

Because especially in the developing countries the only access to Internet are mobile devices, deve...

The Mobile Internet requires enhanced security services available to all mobile subscribers in a dynamic fashion. A network-wide Virtual Private Network (VPN) deployment scenario over the General Packet Radio Service (GPRS) is proposed and analyzed from a security viewpoint. The proposed security scheme improves the level of protection that is currently supported in GPRS and facilitates the rea...

This paper aims to examine factors affecting subscribers’ intention towards using 3G mobile service. Cross sectional data were collected from 100 respondents through a survey. Data were then analyzed by means of multiple regression analysis. The findings verified the research hypotheses, and confirmed that Perceived Usefulness, Perceived Ease of Use and Attitude are jointly responsible in deter...

mobile subscribers has increased much faster than anticipated. This trend is expected to continue in the future. According to the Universal Mobile Telecommunication System (UMTS) Forum [1], there will be around 400 million mobile subscribers worldwide in the year 2000 and almost 1800 million subscribers in the year 2010.

Delivering multimedia services to roaming subscribers raises significant challenges for content providers. There are a number of reasons for this; however, the principal difficulties arise from the inherent differences between the nature of mobile computing usage, and that of its static counterpart. The harnessing of appropriate contextual elements pertaining to a mobile subscriber at any given...

because of the need to develop specific measurement scales for different services industries, this study aimed to empirically develop a reliable and valid model specifically for measuring mobile telecommunication service quality. a multidimensional measurement model (ms-qual) has been proposed based on an extensive literature review and then, to assess the model validity, convergent and discrim...
