There was a mistake relating to a roaming network service package that my sister bought from one of the telephone networks in Thailand. She paid 2,000 Baht (the Baht is the currency of Thailand) for this package. She and her friends were going on a self-“guided” and organized tour to Japan and wanted to use the internet as an integral part of travelling. She or her friends did not speak Japanese. Unfortunately, the internet did not work using that roaming package. Not having roaming facility greatly affected the travelling quality of my sister’s vacation trip to Japan. It also completely messed up her itinerary. My sister used hotel Wi-Fi to contact me and asked that I call the telephone service and solve the problem.

This paper seeks to present an overview and some preliminary results of the DAMe project. The main goal of this project was to define a unified authentication and authorisation system for federated services hosted in the eduroam network.

This paper presents the main initiatives and technologies related to the DAMe project and some first designs that show how the main goals are already being achieved.

At present, there are several activities of DAMe in progress, such as the design and implementation of a multiplatform PEAP supplicant, the middleware for managing the SSO tokens and the design of new common services for eduGAIN.

This paper is based on results from the DAMe project and the knowledge of the authors and will be of interest to those in the same field.

It is often stated that mobile wireless computing is going to be the next big technology revolution that will grip the world in the same way mobile telephones did in the 1990s. However, while the technology is rapidly improving, the rate of uptake has been lower than expected. This paper describes some of the reasons for this, and discusses some of the proposed solutions.

This article seeks to analyze the initiative of the European Commission that studied the feasibility of measures that would lead significant market players to license their interoperability information under the Digital Agenda.

The significance of the abuse of dominance regime and the electronic communications framework in ensuring access to interoperability information in the ICT sector is studied by way of analyzing legislation and case law. Against the background of these two existing regulatory regimes, the proposals that the Commission made in its recently published Staff Working Document are evaluated.

The Microsoft case illustrates that the abuse of dominance regime under European competition law is not very effective to remedy interoperability issues in a structural way. An ex ante regime will enable the ICT industry to reap the full benefits of interoperability on a broader scale. Since the Commission's initiative seems to target interoperability among software products, the electronic communications regime is not applicable. A new regulatory regime should therefore be established. As the desirability of a mandatory regime can be questioned, the adoption of soft law measures seems to be the preferred option.

By putting the initiative of the Commission to examine measures that promote access to interoperability information under the Digital Agenda into its broader regulatory context, the article contributes to the discussion on the possible ways to ensure interoperability in the ICT sector.

The purpose of this paper is to report on a program being developed by the Texas A&M University business librarians to employ a street team construct to promote the resources and services of the Texas A&M University's West Campus Business Library and to leverage the importance of “peer relationship” so evident in today's university student.

The paper is a descriptive analysis of the program.

This unique marketing program seeks to increase the awareness of Texas A&M University business students to the resources and services of the West Campus Business Library. By tapping into the youthful energy of these very students, the program proposes to utilize cutting edge cultural and social trends that are aimed to improve communications with its most important customers.

The program seeks to improve communication with students at an extremely low cost.

Discussion includes the rationale for adopting the guerilla marketing technique of street teams, the program planning process, and a discussion of assessment strategies.

The research analyses the spatial-temporal behaviour of international visitors using mobile positioning data (MPD) in three second-tier cities in Hungary: Szeged, Debrecen and Pécs. The purpose of this study is to identify the origins of visitors, length of stay, seasonal concentrations and mobility between cities.

A large volume of data generated by foreign mobile phone users was processed and analysed for six consecutive months in 2018. The movements of around 3.5 million foreigners visiting Hungary were captured.

The data showed significant differences in tourist turnover, mobility patterns and flows indicating different levels of tourism activity and potential in the three cities. This included day trips, cross-border tourism, seasonal fluctuations and activity-driven demand (e.g. special events and cultural tourism).

MPD cannot fully explain or predict drivers of visitor behaviour, such as purpose of visit, the precise activities that they undertake there and the experiences that they gain. It can, however, provide information on spatial and temporal flows, patterns and concentrations of visitors.

The investigated cities should follow distinct tourism development policies to attract more tourists and strengthen the links with their neighbouring destinations at the same time as differentiating themselves through marketing as competitive alternative destinations.

Augmenting tourism has socio-economic implications for residents and communities. The development of cultural tourism and local event-based tourism must incorporate community needs.

The paper analyses the extent to which MPD can provide insights into visitors’ spatio-temporal mobility and flows in relatively under-visited second-tier cities and it highlights opportunities and gaps for big data research in an urban context.

The purpose of this paper is to understand the conditions that enabled the end of roaming charges in East Africa in 2006, achieving in weeks what European regulators had struggled with for nearly a decade. To do so it aims to explore the factors that drove marginalized operator Zain to seize the competitive advantage created by it having licenses in three adjoining markets.

The paper draws on the theory of disruptive competition and innovation pioneered by Clayton Christensen to explain the innovative and disruptive nature of the Zain business model. It is drawn on to explain why, despite Zain being unable ultimately to dominate its competitors, it had a sustained disruptive effect on the entire market. This provides a theoretical lens through which to view the empirical evidence acquired through in‐depth interviews and market analysis. This is used to develop a detailed case study on the dropping of roaming charges in East Africa.

The case study demonstrates the importance of an enabling policy and regulatory environment, which allowed operators to integrate historically separate national networks into cross‐border operations, undermining roaming markets in the region and ending roaming charges in East Africa forever. With the high price of communications in East Africa and the premium charges placed on international mobile roaming, the effect of this move was to compel other regional operators to follow suit, and further, to institute various other pricing strategies in an attempt to retain or recover their dominant positions. As a result, not only did roaming charges disappear across major networks, but the prices of various other mobile services also fell as subscriber numbers soared.

Research in this area is severely constrained by the inability to access pricing, traffic and revenue data from operators that is regarded as competitively sensitive. As a result it is often difficult to assess the immediate gains and losses of competitors and failure to get consistent data over time, the ability to assess lags and long‐term positions. A longer term review of the impact of these developments on pricing and the dynamics of the East African market in future would provide valuable insight into the longer term effects of these developments.

As policy makers and regulators elsewhere in Africa start to emulate European “best practice” regulation, despite the difficulties mature and resourced regulators in the European Union face in instituting legally binding maximum tariffs for roaming, a valuable alternative policy and regulatory strategy exists in the creation of enabling competitive environments in which incentives to reduce to eliminate roaming charge, rather than retain environments in which international call termination on roaming phones can be arbitraged.

Even though ultimately Zain was not successful as a disruptive competitor, it forced the dominant operators to reduce their roaming charges that resulted in sustained welfare gains.

This paper provides both novel theoretical insight and empirical evidence to explain the end of roaming charges in East Africa. It nuances perceptions in the popular and technical press that this was purely a market strategy that could be emulated anywhere else. It highlights the necessary enabling policy and regulatory environment that needed to be created and provides empirical evidence of the impact on competition in the market and analyses the outcomes of Zain's short term business strategy, against the longer term disruptive effect on the market.

Tariffs for international mobile roaming (IMR) are often viewed by governments as an additional tax on international trade and on tourism. IMR customer bills may appear to be arbitrary and sometimes excessive. The purpose of this paper is therefore to set out a pragmatic approach to assessing international charges for mobile roaming, making use of a realistic cost model of the international roaming process and its cost elements, at a level that is useful to regulatory authorities and operators.

The discussion presented is based on industry practices for handling voice calls and data sessions with the mobile network operators (MNOs) business model, based on industry sources. The basic mechanisms use two common constructs from business analysis – business processes and use-cases – to provide a simplified form of activity-based costing. This provides a model suitable for national regulatory authorities to move towards cost-based IMR tariffs.

Using a perspective on costs based on a bottom-up survey procedure for elucidating the key information, the paper presents the cost elements for the various IMR network components and business processes, with an approach suitable for analysing both wholesale and retail pricing.

The method is specifically designed to overcome the key problem of such approaches, the limitations set by differences in network technologies, network topology, operational scale and the engineering, as well as MNO business model and accounting practices, which otherwise would preclude the method presented here from being vendor neutral.

Vendor and network engineering neutrality implies the approach can be used to compare different MNOs in terms of the validity of their IMR charges and whether they are cost based.

Impacts on society of so-called “bill-shock” have become quite common, increasingly for data sessions. The cost model presented here was developed with the intention of improving the accountability and transparency of the mobile roaming market. It thus assists in the introduction of cost-based tariffs over an economic region, such the European Union.

The paper examines the practical implications of building large-scale cost models for assessing the real IMR costs, a modelling exercise that has not been seen elsewhere in terms of its approach and neutrality as to MNO structure and assets.
