    Wireless networks have gone through several years of evolution until now and will continue to do so in order to cater for the varying needs of its users. These demands are expected to continue to grow even more in the future, both in size and variability. Hence, the 5G technology needs to consider these variabilities in service demands and potential data explosion which could accompany users’ demands at the core of its architecture. For 5G mobile network to handle these foreseen challenges, network slicing \cite{c13} is seen as a potential path to tread as its standardization is progressing. In light of the proposed 5G network architecture and to support and end-to-end mobile network slicing, we implemented radio access network (RAN) slicing over a virtualized evolved Node B (eNodeB) and ensured multiple core network slices could communicate through it successfully. Our results, challenges and further research path are presented in this thesis report

    La tĂ©lĂ©communication mobile connecte les personnes de n'importe oĂč Ă  tout moment. La transmission de la voix et des donnĂ©es Ă  travers les rĂ©seaux de tĂ©lĂ©communication mobile permet d'envoyer des informations et de diriger des transactions d'une maniĂšre nouvelle. Cela crĂ©e un nouveau domaine d'affaires qui s'appelle du commerce mobile, une affaire Ă©tendue basĂ©e sur l'Internet avec de nombreux des caractĂ©ristiques uniques ajoutĂ©s. Comme un soutien fondamental du plate-forme, les rĂ©seaux de la tĂ©lĂ©communication mobile joue un rĂŽle essentiel dans le commerce mobile. Leurs caractĂ©ristiques techniques et le dĂ©ploiement dĂ©terminent l'essence pour le commerce mobile. Dans cette mĂ©moire, nous Ă©tudions et prĂ©sentons les caractĂ©ristiques techniques des technologies communications mobiles du rĂ©seau 1G Ă  3G et au-delĂ . Nous Ă©tudions Ă©galement les technologies WLAN et WAP qui sont courantes dans le commerce mobile en Chine et dans le monde. Le commerce mobile est en train de se dĂ©velopper, le nombre d'utilisateurs de tĂ©lĂ©phones mobiles sont de plus en plus en Chine et dans ce monde. Les utilisateurs mobiles Ă©normes en Chine ainsi que la maturitĂ© des technologies 3G affichent un fort potentiel pour offrir et d'adopter plus les nouveaux services mobiles. AprĂšs rĂ©viser l'Ă©volution du commerce mobile et l'histoire du succĂšs i-mode au Japon, nous nous concentrons sur le mobile du marchĂ© chinois de maniĂšre Ă  dĂ©couvrir son marchĂ©, l'infrastructure du rĂ©seau mobile, et le modĂšle d'affaires. FondĂ© sur la base de notre enquĂȘte sur le commerce mobile chinois, nous prĂ©sentons, selon notre jugement, les services mobiles et des applications que sont convenables pour la Chine. Parmi eux, nous pensons qu'il y a la tendance sur les services basĂ©s sur la localisation et services orientĂ©es de l'architectures. Cette tendance peut attirer plus d'attention Ă  offrir de nouveaux services. En plus, elle peut offrir des services d'intĂ©gration et de personnalisation qui viennent de fournisseurs de services mobiles et des utilisateurs finaux. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Gestion intĂ©grĂ©e et Ă©cosystĂ©mique, Principe de prĂ©caution, Communication entre acteurs, Risques sur l'environnement et la santĂ©

    End-to-end QoS architecture for 4G scenarios

    Get PDF
    This paper describes the QoS architecture and the corresponding QoS signalling protocols to be developed inside the IST project Daidalos. We address the main results achieved in terms of the definition of the QoS components and its interfaces, the description of the application and network services, definition of the signalling scenarios for the integration of the QoS signalling with the application signalling and with mobility approaches, and specification of the intra- and inter- domain QoS control approaches. We also describe the QoS management of the system, through the Policy–based Management System, and a Real-time Network Monitoring system able to aid in admission control with the results of active and passive measurements. All the elements, interfaces and functionalities take into account multicast services and inherent broadcast networks

    A taxonomy and business analysis for mobile web applications

    Get PDF
    Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2009.Includes bibliographical references (p. 113-115).Mobile web applications refer to web applications on mobile devices, aimed at personalizing, integrating, and discovering mobile contents in user contexts. This thesis presents a comprehensive study of mobile web applications by proposing a new taxonomy for mobile web applications, and conducting a business analysis in the field of mobile web applications. The thesis reviews the current surrounding environment for mobile web applications, namely, web 2.0 and 3.0, wireless communication technology, and Smartphone platform. The recent entry and success of Apple's iPhone greatly enhanced the public awareness of the Smartphone technology. Google's release of open-source Android platform and T-Mobile's deployment of Android-powered "Dream" Smartphone not only intensify the competition among suppliers, but also provide an open-source foundation for mobile web applications. This thesis introduces a new mobile web application taxonomy to systematically study the values and the groupings of the mobile web applications. By introducing features and categories, the taxonomy provides a framework so the related companies and businesses can be comparatively analyzed and summarized. Selected case companies are studied in the light of the taxonomy. The thesis discusses the key issues of mobile web aggregation, namely, mobile application development platform, context modeling, mobile user interface, mobile application logic, and mobile web aggregation strategy.(cont.) "System Thinking" is applied to the management of mobile web application business. The market ecosystem, the value proposition, and the revenue model for mobile web application are described. A system dynamic model is constructed to understand the dynamic among the key factors in the mobile web business. Experimental results are reported in the thesis.by Kevin Hao Liu.S.M
