Reflections on the Use of a Smartphone to Facilitate Qualitative Research in South Africa
This paper describes conditions that led to the use of a smartphone to collect qualitative data instead of using a digital voice recorder as the standard device for recording of interviews. Through reviewing technical documents, the paper defines a smartphone and describes its applications that are useful in the research process. It further points out possible uses of other applications of a smartphone in the research process. The paper concludes that a smartphone is a valuable device to researchers
An Evaluation and Selection of 3G Mobile Value-Added Service
As the wireless communication and mobile phone market develop rapidly, telecommunication dealers provide diverse mobile value-added services for consumers to choose from. However, which mobile value-added services are those consumers need have become a worthy issue for discussion. In this empirical study, cluster analyses and analytic hierarchy processes are used to investigate and understand the need for cognition in the young users (20-29 years old). The selected subjects’ preferences for services, like mobile communication service, mobile entertainment service, mobile information service and mobile transaction service are evaluated. By surveying the subjects’ need for recognition, cluster analysis can further be used to cluster diverse mobile value-added services. Furthermore, by means of the Analytic Hierarchy Process (AHP), services that subjects pay more attention to can be sifted out for the further development of service functions. The results of analysis indicate that the mobile value-added services young users pay most attention to are: wireless emergency services in the communications category, mobile mapping in the information category, mobile taxi services in the communication category, contact list in the communication category and short messaging service in the communications category
Autonomic service configuration for telecommunication MASs with extended role-based GAIA and JADEx
Autonomie Communications have attracted huge attention recently for the management of telecommunication networks in the European Network Research Community. The purpose of this research is to offer the abilities such as autonomy, scalability, adaptation as well as simplicity for management application in complex networks. The accomplished networks inspired by biological mechanisms or market-based concepts could enable agents to be of intelligence, scalablility, and interoperabliliry in the management functional domains with regards to the large volume requirements from services' fulfillment perspective in decentralized Multi-Agent Systems. In accordance with TMF and FIPA specifications and requirements, the autonomy attributes self-configuring, self-adapting, self-limiting, self-preserving, and self-optimizing are involved into our simulation. Resource allocation requests are bidded for a long session in the multi-unit Vickrey-Clarke-Groves auction. This design adopts the software development methodology-GAIA and the framework-JADEx. We have shown multiple service configuration in dynamic network can be nearly optimized by autonomie behaviors via bidding according to business objectives for getting maximum revenues. We conclude this end-to-end approach maintains self-managing capability, easy-to-implement scalability, and more incentively compatible and efficient over other common implementation so that it could achieve the optimal solution to the flexible requirements for the Service Fulfillment for advanced IP networks. © 2005 IEEE

Business model requirements and challenges in the mobile telecommunication sector
The telecommunications business is undergoing a critical revolution, driven by innovative technologies, globalization, and deregulation. Cellular networks and telecommunications bring radical changes to the way telecom businesses are conducted. Globalization, on the other hand, is tearing down legacy barriers and forcing monopolistic national carriers to compete internationally. Moreover, the noticeable progress of many countries towards deregulation coupled with liberalization is significantly increasing telecom market power and allowing severe competition. The implications of this transition have changed the business rules of the telecom industry. In addition, entrants into the cellular industry have had severe difficulties due to inexistent or weak Business Models (BMs). Designing a BM for a mobile network operator is complex and requires multiple actors to balance different and often conflicting design requirements. Hence, there is a need to enhance operators’ ability in determining what constitutes the most viable business model to meet their strategic objectives within this turbulent environment. In this paper, the authors identify the main mobile BM dimensions along with their interdependencies and further analysis provides mobile network operators with insights to improve their business models in this new ‘boundary-less’ landscape
Services on the Mobile Internet Service-Driven Technology Development
The purpose of this thesis is to describe and analyze the services on the mobile Internet and to identify when, where, and how these service offerings can be profitable. The thesis is a qualitative study based on in-depth interviews with key stakeholders in the service value chain and with relevant experts. Case methodology have been used to gather and structure the empirical material from three cases, i-mode in Japan, SMS in Europe, and BlackBerry in the USA to be able to generate new theory as well as expand on existing theory. The analysis, based on the three cases, generates and validates a model for successful service strategy on the mobile Internet. The service strategy is called service-driven technology development. Service-driven technology development explains the success of the three cases and provides a framework to successfully develop, implement, and maintain profitable services on the mobile Internet
