Towards global service level guarantee within autonomic computing systems
2011
International audience; In this paper, we specify a global service level guarantee including not only QoS but also security and taking into account user mobility. This global service level could be guaranteed within several autonomic computing systems managed by different autonomic domain managers. For that purpose, we propose an end-to-end Service Level Negotiation Protocol, called SLNP, to provide those autonomic managers with a negotiation capability. This allows achieving an agreement on the service level of each offered service between the different domains involved in the transport of that service. SLNP Implementation is made of Web Services technologies to enable interoperability in …
How does information technology– based service degradation influence consumers’ use of services? An information technology–based service degradation …
2019
Information technology is crucial for modern services. Service delivery may include a complex mix of information technology and telecommunication providers, global networks and customers’ information technology devices. This research focuses on service failures that are caused by information technology problems, which we conceptualize as information technology-based service degradation (ITSD). When information technology-based service degradation occurs in a modern service, the information technology problem may originate from the service provider, another partner or any information technology equipment involved. But the customer may not be able to pinpoint the source of the problem immedi…
Unlocking behaviors of long-term service consumers : the role of action inertia
2017
Purpose The purpose of this paper is to examine the antecedents of word-of-mouth (WOM) in long-term service settings. Specifically, the authors examine the moderating role of action inertia in the relationships between satisfaction and repatronage intention, satisfaction and WOM, and repatronage intention and WOM. Design/methodology/approach The proposed model was empirically tested using survey data from 1,385 telecommunications service subscribers. The data were analyzed using partial least squares path modeling. Findings Results suggest that a positive link between repatronage intention and WOM, hereto a neglected relationship in the marketing literature, in contrast to previous literat…
Case study for 3G/UMTS services and billing methods
2001
The 3G/UMTS-networks and services will provide a wide range of telecommunication services. To achieve, this, we need a new view to networks, network services and service abilities. The amount of service providers in the 3G networks will be at least the same than in the present Internet. The amount of users in the 3G networks will overgrow the user amount of Internet forming a global worldwide communication society. This paper discusses customer billing in the 3G world. There are some main issues that are not very, clear to all 3G service and network providers, which however, should be settled before, 3G networks are operational. One of the most important matters is the QoS (Quality of Servi…
What benefits couldn't ‘Joyn’ enjoy?
2019
Abstract This case study examines the dynamics of the mobile instant messenger (MIM) market in Korea. MIMs have been disrupting traditional mobile communication services such as voice, SMS, and media content. In response to MIMs, Korean Mobile Network Operators (MNOs) jointly launched a standards-based messenger service called Joyn, which ultimately performed poorly. Focusing on Joyn, this study analyses the changing status of MNOs and their counter-strategies against MIMs in the context of the turbulent mobile services market. For the analysis, we use a co-evolutionary framework encompassing technological, market, and regulatory domains and apply a platform competition perspective. The cas…
A framework for IoT service experiment platforms in smart-city environments
2016
Cities provide an excellent platform for gathering and detection of massive amount of data from cities and citizens. Emergence of new digital technologies inspires not only city governments but also city residents, researchers, companies and other stakeholders in discovering and creating new innovative solutions to solve urban challenges and improve peoples´ everyday life. Developing novel Internet of Things (IoT) solutions for cities and citizens requires facilities where IoT applications and services can be tested and experimented. The challenge for many smart-city test and experimentation platforms (TEPs), like living labs, has been the lack of sustainable value creation model. This has …
An RF Wireless Power Transfer system to power battery-free devices for asset tracking
2019
Internet of Things (IoT) and Wireless Sensor Networks (WSN) infrastructures are becoming more and more available and diffused. One major outcome is the development of new services that help to make everyday life easier and better. One of those to which this paper reserves special attention is asset tracking which refers to the method of tracking physical assets. This service is very well based on IoT infrastructure and, due to the enormous number of objects to be traced, desperately needs the availability of inexpensive tags with sensing capabilities, that can be conveniently monitored from a long distance and require no maintenance. For this, engineers are called to face very challenging i…
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…
Discovering web services in social web service repositories using deep variational autoencoders
2020
Abstract Web Service registries have progressively evolved to social networks-like software repositories. Users cooperate to produce an ever-growing, rich source of Web APIs upon which new value-added Web applications can be built. Such users often interact in order to follow, comment on, consume and compose services published by other users. In this context, Web Service discovery is a core functionality of modern registries as needed Web Services must be discovered before being consumed or composed. Many efforts to provide effective keyword-based service discovery mechanisms are based on Information Retrieval techniques as services are described using structured or unstructured textdocumen…
