Content usage management system method, and program providing medium therefor

Abstract: When the encrypted content is provided from a service provider to a user device, a usage log including information of the content usage fee is created in the user device. The created usage log is then sent to the service provider. The service provider compares the content usage fee in the received usage log with a predetermined threshold. If the content usage fee is found to exceed the predetermined threshold, the service provider requests a clearing center to inquire about the electronic money balance of the user. If it is determined that it seems difficult to collect money from the user, the transmission of a content key to the user is suspended. The clearing center also creates an issue log in which the effective period and an allowable amount of money spent by the user are set, and performs settlement processing only when the payment of the content usage fee has been made within the effective period.

A ubiquitous mobile communication architecture for next-generation heterogeneous wireless systems

Abstract: Rapid progress in research and development of wireless networking and communication technologies have created different types of wireless systems (e.g., Bluetooth, IEEE 802.11, UMTS, and satellite networks). These systems are envisioned to coordinate with each other to provide ubiquitous high-data-rate services to mobile users. In this article, the architecture for ubiquitous mobile communications (AMC) is introduced that integrates these heterogeneous wireless systems. AMC eliminates the need for direct service level agreements among service providers by using a third party, a network interoperating agent. Instead of deploying a totally new infrastructure, AMC extends the existing infrastructure to integrate heterogeneous wireless systems. It uses IP as the interconnection protocol. By using IP as the gluing protocol, transparency to the heterogeneities of the individual systems is achieved in AMC. Third-party-based authentication and billing algorithms are designed for AMC. New mobility management protocols are also developed to support seamless roaming between different wireless systems.

The impact of customer participation and service expectation on Locus attributions following service failure

Abstract: This study explores the impact of two factors that are prominent in the service literature: customer participation and service expectation. Owing to the interactive nature of services, customers often participate in the co‐production of the service. In addition, customers normally enter into the service with certain expectations regarding the level of service they are likely to receive. The survey argues that the participative roles adopted by customers in service specification and delivery and their pre‐encounter service expectations influence how customers attribute the causes of service failure. Finally, the implications from the findings are discussed and directions for future research are provided. The effect of emotional response caused by a service failure on locus attributions remains to be further investigated.

On Radio Access Network Slicing from a Radio Resource Management Perspective

Abstract: Network slicing is a fundamental capability for future 5G networks to properly support current and envisioned future application scenarios. Network slicing facilitates a cost-effective deployment and operation of multiple logical networks over a common physical network infrastructure such that each network is customized to best serve the needs of specific applications (e.g., mobile broadband, Internet of Things applications) and/or communications service providers (e.g., special purpose service providers for different sectors such as public safety, utilities, smart city, and automobiles). Slicing a RAN becomes particularly challenging due to the inherently shared nature of the radio channel and the potential influence that any transmitter may have on any receiver. In this respect, this article analyzes the RAN slicing problem in a multi-cell network in relation to the RRM functionalities that can be used as a support for splitting the radio resources among the RAN slices. Four different RAN slicing approaches are presented and compared from different perspectives, such as the granularity in the assignment of radio resources and the degrees of isolation and customization.

Scoping the Sharing Economy: Origins, Definitions, Impact and Regulatory Issues

Abstract: This report selectively draws on the systematic review of a large set of data sources, which is presented elsewhere, and comprises 430 secondary sources (Codagnone, 2016). The report also provides a critical overview of key analytical, empirical, and normative dimensions of the ‘sharing economy’. It reviews both the rhetorical and controversial debates currently surrounding the topics and the available empirical evidence in order to sharpen our understanding of relevant policy and regulatory issues. The broad umbrella term 'sharing economy' is critically assessed and a typology developed that identifies the commercial 'peer to peer' sharing economy as the main focus of both controversies and policy-relevant issues. Empirical evidence of the benefits and costs of the sharing economy and its implications for sustainability and employment is very limited and inconclusive, particularly as regards the European landscape. This critical review, hence, shows that, as yet, there are no unambiguous answers to some of the fundamental questions about the ‘sharing economy’. The available research is too limited and patchy to give us a comprehensive and coherent picture. This report’s main contribution is to clear some of the conceptual and empirical fog around the ‘sharing economy’ and to identify where possible answers might be found in the future. It is suggested that the definition of sharing platforms should focus on P2P activities, as most of the policy concerns are found there. These include regulatory and consumer protection issues resulting from the informal production of services, potentially unfair competition with formal B2C service providers, and questions related to dominance and market power of P2P platform operators as commercial businesses.
