Mobility Management, Quality of Service, and Security in the Design of Next Generation Wireless Network

The next generation wireless network needs to provide seamless roaming among various access technologies in a heterogeneous environment. In allowing users to access any system at anytime and anywhere, the performance of mobility-enabled protocols is important. While Mobile IPv6 is generally used to support macro-mobility, integrating Mobile IPv6 with Session Initiation Protocol (SIP) to support IP traffic will lead to improved mobility performance. Advanced resource management techniques will ensure Quality of Service (QoS) during real-time mobility within the Next Generation Network (NGN) platform. The techniques may use a QoS Manager to allow end-to-end coordination and adaptation of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover. Heterogeneous networks raise many challenges in security. A security entity can be configured within the QoS Manager to allow authentication and to maintain trust relationships in order to minimize threats during system handover. The next generation network needs to meet the above requirements of mobility, QoS, and security

Mobile Operator Publishing and Entertainment Platform

There is a gap between mobile Operators and content Publishers, hindering established small and medium sized publishers to enter the mobile market despite its commercial potential. A Mobile Operator Publishing and Entertainment Platform enables the creation of a new category of mobile service called a mobile magazine. An m-Mag (mobile magazine) is a next generation mobile publishing service that is made available from a mobile operator's portal, that is integrated with value added mobile data services and that uses the operator's billing capabilities to charge consumers for access to the magazine. Using Parlay/OSA as an open approach, the m-Mag platform can integrate into an operator's network using standardised APIs and is portable across different operator networks

Energy-efficient mobile Web computing

Next-generation Web services will be primarily accessed through mobile devices. However, mobile devices are low-performance and stringently energy-constrained. In my dissertation, I propose the design of a high-performance and energy-efficient mobile Web computing substrate. It is a hardware/software co-designed system that delivers satisfactory user quality-of-service (QoS) experience on a mobile energy budget. The key insight is that the traditional interfaces between different Web stacks need to be enhanced with new abstractions that express user QoS experience and that expose architectural-level complexities. On the basis of the enhanced interfaces, I propose synergistic cross-layer optimizations across the processor architecture, Web runtime, programming language, and application layers to maximize the whole system efficiency. The contributions made in this dissertation will likely have a long-term impact because the target application domain, the Web, is becoming a universal mobile development platform, and because our solutions target the fundamental computation layers of the Web domain.Electrical and Computer Engineerin

Adaptive e-learning grid platform

Many analysts believe that more and more organizations are looking to introduce e-learning as a way to solve critical business problems and as a vital component of an integrated approach to their training solutions. So we are introducing our next generation, e-learning grid platform to meet the evolving needs of the market, which include technology, content and services. This platform will define a new mode of service interaction and application creation. It proposes a user-friendly method for deploying interactive (mobile) devices and for accessing new and innovative added value services. The specific infrastructure will provide the technology necessary to access, arrange, manage and make available e-learning services and applications, for both individual end users and business

Migration strategies for competitive advantage of mobile network operators

Thesis (S.M.M.O.T.)--Massachusetts Institute of Technology, Sloan School of Management, Management of Technology Program, 2003.Includes bibliographical references (leaves 145-149).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Innovation in platform industries, including mobile telecommunications, has a great impact on societies and economies; hence a migration from an existing platform to the subsequent one should be progressed under careful forecasting, weighed scenarios and strategies that encompass a broad view. This thesis analyzes why mobile network operators are struggling to move from the second generation (2G) and its derivatives to the third generation (3G) technologies and proposes migration strategies, which allow them to sustain their competitive advantage. First, a migration model is proposed as a reinforcing loop model composed of two dynamics, "Platform Migration" caused by a shortage of network capacity, and "Service Innovation" triggered by a decline in ARPU (Average Revenue Per User). Platform migration is an implementation process for new platform technologies and can be categorized into Revolution-type and Evolution-type. After these two schemes have been evaluated through case studies, Collaboration-type migration, an enhanced Evolution-type, is proposed for future, technically diversified situations. Service Innovation is a process for creating new profitable services to give further revenue growth. Empirical analysis clarifies that mental breakthrough management is a common approach in the mobile industry and proposes that a mixture of corporate, partner and market initiatives be adopted for diversified customer preference. This thesis then proposes the following strategies for future successful migration: first, mobile network operators should drive the migration cycle powerfully, concentrating on successive service innovation dynamics for their revenue growth and the next platform migration. Second, they should choose migration schemes carefully according to their level of technology leadership, value chain leadership and investment capability. Finally, service platform should be considered for realization of innovative services with Partnership Dynamics.by Hisakazu Tsuboya.S.M.M.O.T
