The impact of service bundles on the mechanism through which functional value and price value affect WOM intent
2017
Purpose The purpose of this paper is to contribute toward the current limited understanding of service bundles by investigating how purchasers of combined product-service bundles (bundle customers) differ from those purchasing a product and associated service separately (non-bundle customers). Design/methodology/approach The hypothesized effects were tested on a representative sample of mobile phone subscribers in Finland, through a multi-group moderated analysis using variance-based structural equation modeling. Findings While functional value had a stronger effect on attitude for bundle customers, price value is a stronger determinant of attitude for non-bundle customers. There was no di…
UWSIO: Towards automatic orchestration for the deployment of 5G monitoring services from bare metal
2018
The next generation mobile networks 5G are currently being intensively developed and standardized globally, with commercial prototyping 5G connections already emerging. At the 5G system level, one of the Key Performance Indicators (KPIs) defining 5G is substantially reduced service creation time for 5G network operators and/or service providers to increase the system efficiency and thus reduce operational costs. In this work, we focus on realize this challenging KPI in terms of speedy creation of monitoring services for 5G operators from scratch (no operating system pre-installed). A new 5G infrastructure orchestrator UWSIO is proposed to achieve fully automated deployment of 5G monitoring …
Privacy-preserving data allocation in decentralized online social networks
2016
International audience; Distributed Online Social Networks (DOSNs) have been recently proposed as an alternative to centralized solutions to allow a major control of the users over their own data. Since there is no centralized service provider which decides the term of service, the DOSNs infrastructure exploits users’ devices to take on the online social network services. In this paper, we propose a data allocation strategy for DOSNs which exploits the privacy policies of the users to increase the availability of the users’ contents without diverging from their privacy preferences. A set of replicas of the profile’s content of a user U are stored on the devices of other users who are entitl…
Joint Radio and Computational Resource Allocation in IoT Fog Computing
2018
The current cloud-based Internet-of-Things (IoT) model has revealed great potential in offering storage and computing services to the IoT users. Fog computing, as an emerging paradigm to complement the cloud computing platform, has been proposed to extend the IoT role to the edge of the network. With fog computing, service providers can exchange the control signals with the users for specific task requirements, and offload users’ delay-sensitive tasks directly to the widely distributed fog nodes at the network edge, and thus improving user experience. So far, most existing works have focused on either the radio or computational resource allocation in the fog computing. In this work, we inve…
Which Test Artifacts Testing Service Providers should Reuse and How? Experiences from a Case Study in the Chinese ICT Sourcing Market
2011
Software testing service providers are facing new requirements to shorten service times, lower costs, and increase service customization and quality. Reuse of test artifacts is a possible solution that can help providers to meet the requirements because reuse can improve software quality and productivity. However, the extant literature does not explain in depth which test artifacts should be reused and how. This paper focuses on ICT-enabled sourcing of software testing services in the Chinese market to identify the most important reusable test artifacts. There are two reasons for this research. First, most Chinese service providers are small or medium-sized and have to overcome obstacles su…
Software-as-a-Service in the Telecommunication Industry: Problems and Opportunities
2010
This paper examines the telecommunication software market and the adoption of topical Software-as-a-Service (SaaS) model in this vertical market. The aim of this paper is to estimate which telecommunication software products are likely to be provided as a Service, and to examine the potential factors disallowing SaaS adoption. The set aim is pursued by studying both the supplying software vendors and the communication service providers (CSP) as customers. A set of thematic interviews, software industry statistics and information disclosed by the software vendors are used in the analysis. The results of the analysis reveal challenges in adopting SaaS for telecommunication software as well as…
Appunti per una ricerca sui servizi di disposizione di ordini di pagamento

This essay will explore issues related to the Payment Initiation Service, which are currently subject to Directive 2015/2366/EC (Payment Services Directive II) and, in Italy, to the Law Decree n. 11, 27th January 2010. The analysis will examine its key points, through the study of the nature of relations between payment service users and payment initiation service providers; as well as those between the latter and account servicing payment service providers. Moreover, this article will explore rights and obligations of all parties in payment transaction. Lastly, it will access criteria to allocate liability when a transaction initiated through a payment initiation service provider was unaut…
Inter-provider AAA and Billing of VoIP Users with Token-based Method
2007
With the increasing popularity of wireless LAN technology, providers of real-time voice over IP (VoIP) services, known as voice service providers (VSP), are asking for roaming solutions and AAA (Authentication, Authorization and Accounting) methods that allow users to use their services from any available public Internet access network. In this paper we propose an AAA and billing architecture that allows users of VSPs to have access to the Internet from wired and wireless access networks provided by both traditional carriers, such as 3G providers, and wireless local access network (WLAN) providers. We propose a token-based AAA method that allows users of VoIP services to have their VSPs as …
