Leveraging NFC and LBS Technologies to Improve User Experiences

In old days, most of the enterprise collect their customer experience by using questionnaire. However, with the emergence of IT technology, many new way/methodology could enhance your customers experience. In this paper, we focus on the topic of how to well utilize technologies nowadays to improve user experience. We propose service experience modeling for call center and online web sites, and leveraging Near Field Communication (NFC) and Location Based Service (LBS) in people daily life. We also present a demonstration that fully describes how these technologies be used to improve users satisfaction.

Efficient and Flexible Emergency Communications in Next Generation Mobile Network

In recent years, the frequency of disaster occurrence significantly increases. Although the information technology is advanced as well, the advantage of leveraging information technology on disaster prevention and recovery has not been effectively utilized yet. Undoubtedly, natural disasters have already exposed the deficiency of existing emergency communications system. In this system, disaster warning subsystem is built upon conventional TV and radio broadcasting, while the rescue mission relied on basic GSM and satellite communications. These traditional technologies can not satisfy the critical timing requirements of disaster warning and emergency medical service. In this paper, we describe an efficient and flexible methodology to develop emergency communications system in next generation mobile networks. We also propose a proof-of-concept prototype to show the feasibility and efficiency of the proposed methodology.

When social networking meets the next generation network

As mobile technologies evolved, the mobile networks provided users not only high mobility, but also high data rates and flexible services. Meanwhile, Internet services had been very successful from 1970s to date. However, the Internet and the mobile telecommunications evolved separately and were not compatible until 3GPP proposed the IP Multimedia Subsystem (IMS). In this paper, we first introduce mobile Web 2.0 application creation in the next generation IMS network. Then we propose a proof-of-concept service called “JoinMe” on the IBM-NCTU IMS network to study how a social networking service can be created for mobile networks.

When Social Network Meets Mobile Device! - An Efficient and Collaborative Framework for Mobile Application

In the emergence of social network application and the thriving popularity of mobile device, it is worthy to investigate the applications that could leverage the advantage of these new technologies and the business value gained from such framework. In this paper, we will introduce the architecture of the framework first. Then we will take a paperless conference as an example to demonstrate how the framework/application works.

Do We Have Tools for Developing Green Applications? - IDE Tool with Power Management Computation Plugin

Power resources on the mobile device are always valuable, meanwhile there are 4.6 billion mobile-phone subscribers worldwide. The total amount of energy consumed and the carbon footprint on those mobile devices is considerable which implies developing tools for green applications to become ever more critical. However, there is currently no effective way for application developers to know the power consumption of their applications, nor a development tool to disable unnecessary or optional functions when device power reaches to lower levels. In this paper, we propose an application development tool that provides the power consumption information in integrated development environment (IDE) tools. By using our tool, application developers can clearly evaluate power consumption of applications they develop, and decide whether to down grade or turn off minor functions or features to switch to power saving mode while power resource is limited.
