The widespread use and increasing capabilities of mobiles devices are making them a viable platform for offering mobile services. However, the increasing resource demands of mobile services and the inherent constraints of mobile devices limit the quality and type of functionality that can be offered, preventing mobile devices from exploiting their full potential as reliable service providers. Computation...
The use of mobile devices as data service providers is on the rise. Mobile devices feature a large set of distinct characteristics that qualify them to be the most convenient computing platform for online services, both as consumers and providers. Mobile devices can take advantage of their mobility to provide location-based services and their association to a specific user to customize service offerings...
The explosive growth of mobile devices and wireless networks has raised the interest for information and online service access anywhere and anytime. Due to user mobility, users will have a much closer relationship with their surrounding physical environment and will thus have a much stronger need for search and consume services that are relevant to that environment. This need has driven the development...
Today's computationally able mobile devices are capable of acting as service providers as opposed to their traditional role as consumers. To address the challenges associated with the development of these mobile services, we have developed Odin, a middleware which masks complexity, allowing rapid development of mobile services. Odin, however, does not allow cross-platform development, which is an...
To provide effective mobile services in spite of network disruption, context aware middleware services on mobile devices and application servers can provide services for continuation of applications, by managing mobile services, network connection, limited resources, and context information. In this paper, we propose context aware middleware services for disconnection tolerant mobile application services...
The current ever-growing advances in wireless networking and the great success of mobile computing have contributed to the development of an increasing amount of mobile services. Due to this growth of published services, quality of service (QoS) is becoming a key feature to provide the most appropriate needed service to mobile clients according to their requirements. However, managing QoS represents...
Rich and attractive mobile services have been developed as result of technological advances and emergent mobile business models. Product launching has been improved through packaging and orchestration of services components using service composition techniques. The design of charging systems, which can explore partner information, is a strong enabler for mobile composite services ecosystems. The authors...
Providing mobile services that ensure user satisfaction is one of the most crucial issues for telecommunication carriers and service providers. Traditionally, user satisfaction with the service, i.e., the Quality of Experience (QoE), has been assessed in a laboratory. However, a reliable QoE for a target mobile service in the context of actual use cannot be obtained by laboratory experiment. This...
Mobile devices such as smart phones are increasingly permeating society. With strides in computational power, coupled with the ability to connect to other small devices, smart phones are able to host novel services. To address the repetitive problems associated with mobile service development, namely service reachability, scalability and availability, we have developed Odin, which is a middleware...
Context-aware systems can dynamically adapt to specific dynamic user situations to provide smarter mobile services. In general, context refers to the information that can be used to characterize these situations, and context models are employed to specify contextual information described in context-aware systems. However, even though user context is highly dynamic, existing context models either focus...
M2M communications are capturing the attention of many stakeholders from application developers to mobile operators. Recent initiatives of the GSMA and of mobile operators show their interest in finding new sources of revenue through the adoption of wireless connectivity in a wide range of devices. A route to market these M2M devices can thus involve creating a platform of services that adds value...
Whether or not mobile Internet services add value depends on the context and objective in which they are used. In this paper, we examine whether consumer attitudes towards the added value of mobile services in specific contexts has a positive impact on their general intention to adopt mobile Internet services, by analyzing the results of a large-scale consumer survey. The results indicate that context-of-use...
In this paper we describe a first investigation of continuous service for travel agencies that addresses an often neglected service part of a travel customer cycle: the trip itself. In a user-centred design process, we have developed a service and a system prototype to test our proposed design goals and system design, as well as the service in a realistic environment. We propose a three-level design...
The recent impressive diffusion of smartphones in the mobile industry offers new opportunities to mobile services vendors. One of the most influenced service categories are location-based services. In the present study we investigate the use of location-based services. Based on insights from behavioural decision making a theoretical framework is developed to analyse the individual decision to use...
This study began with a micro view of the mobile services phenomenon, leading to a macro view of social context. To decompose the customer value in the mobile services, using a three-stage coding process through grounded hermeneutics. The contribution of this study is to reveal a theoretically-saturated of a conceptual framework, and to discover the six theoretical propositions.
Services have become increasingly important in today's Web-based applications. Users can access services in an anytime, anywhere manner using a wide variety of mobile devices. Mobile services are a key driver in today's telecommunication market, even though the potential of mobile services has not been fully exploited in existing telecommunication systems. A main driver in these markets are context-...
Over the past few years, rapid advances in wireless broadband networks have been driving the evolution of communication and network technologies towards new mobile services for users. Handover management is still one of the most challenging issues to be solved for seamless mobility in wireless networks. To support mobility on terminal stations mobile WiMAX has been standardized. Moreover to provide...
In china, over 60% of the general population and 80% of young adults own mobile phones. These offer the opportunity for people not only to make phone calls, but to gain the advantages of mobile services such as text and multimedia messaging, mobile learning, etc. Mobile learning is rapidly growing from a set of research projects into worldwide deployment of services for classrooms, workplace training...
In many application fields such as disaster management or personal planning, efficient mobile services should capture users' context in order to provide them with the most appropriate information at a given time. Situation-based services aim towards this direction. They go beyond location-based services as they take a user's current situation into account. Situations include user profiles together...
People on the move have a grown need for real-time information and services anytime and anywhere. In many situations, travelers do not feel at ease and well informed when using public transport. Context information on mobile phones e.g., location and calendar data, can significantly improve the user experience in the current situation. The paper addresses an approach of service offering and usage...
