As the profit margins of 3G mobile network operators gradually decline, and market competition becomes increasingly intensive, they must develop rich and diverse varieties of brand new application services to attrac...

Mobile cloud computing is gaining popularity among mobile users. The ABI Research predicts that the number of mobile cloud computing subscribers is expected to grow from 42.8 million (1.1% of total mobile users) in 2008 to 998 million (19% of total mobile users) in 2014. Despite the hype achieved by mobile cloud computing, the growth of mobile cloud computing subscribers is still below expectat...

Regulators need accurate data on service usage in addition to general information on markets and technology. This study presents a new type of tool, handset-based monitoring, for collecting and analyzing detailed data on usage patterns of mobile subscribers. Results of a panel organized in Finland are described and mapped to the relevant regulatory issues. Observations indicate that Finnish sub...

In this paper, contextual behavior of mobile subscribers is studied with data collected straight from smartphones. The paper develops an approach to study how people use mobile devices in different contexts, by proposing an algorithm that works with device-based sensor data. This approach consists of context detection and data analysis. The context detection algorithm analyses cellular network ...

Recent years have seen an explosive interest in wireless (information) networks that support the mobility of subscribers (and/or terminals). These networks serve as a foundation of future universal, mobile and ubiquitous personal communications systems. Emerging wireless networks share many common characteristics with traditional wire-line networks such as public switched telephone/data network...

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...

In the last two decades, the mobile communications technologies and the Internet have grown almost exponentially, reaching a significant numbers of subscribers around the world. The mobile cellular service got a very large growth of users along with the increase of mobile data services. On the other hand, the Internet provides a great opportunity for users to access the information via fixed an...

Significant opportunities exist for mobile network operators to enhance and refine those services they offer their subscribers. Developments in mobile devices have rendered it feasible to deploy solutions that incorporate an intelligent agent component. The use of agents is particularly apt in those situations that facilitate what may be termed opportunistic services provision. Such services ar...

This paper discusses several practical use cases for deploying network proximity in mobile services. Our research presents here mobile services oriented for either discovering new data for mobile subscribers or for delivering some customized information to them. All applications share the same approach and use the common platform, based on the Wi-Fi proximity. The typical deployment areas for o...

The paper is devoted to methods for identifying payment plans and services by mobile operators which are the best for the given subscribers. We base our research on the model-theoretic approach to domain formalization. We use Formal Concept Analysis for processing the mobile subscriber data. An Ontological Model of the domain “Mobile Networks” is constructed in the scope of this research. The O...
