Space/Terrestrial Mobile Networks Internet Access and QoS Support covers the design of a Global Mobile Broadband System (GMBS) based on the results of the European Commission''s Framework Programme 5 Information Society Technologies (IST) Project SUITED. Many of the latest concept in mobility solutions, network design techniques and internet technologies are presented. The SUITED project has addressed a number of technical issues that are very much state-of-the-art. The presentation of such material in the form of a design of a real network provides a unique source of information.

This book:

Addresses the important topic of heterogeneous networks and the underlying tecyhnologies Describes how to design an integrated satellite/terrestrial infrastructure where all the network components are fully merged together and integrated with the Internet Core network Presents the service scenarios and system requirements of the Global Mobile Broadband System (GMBS) Discusses the necessary QoS support and defines the novel admission control scheme Gauge & Gate Reservation with Independent Probing (GRIP) Covers mobility management including Mobile-IP support and a QoS Support Module (QASM) Describes the functional and network architectures and presents signalling protocols for mobility management in GMBS Presents the design of signalling protocols and their implementation using the Specification and Description Language (SDL)

Space/Terrestrial Mobile Networks Internet Access and QoS Support has an accessible and practical approach to the subject and addresses in detail, the important topic of heterogeneous networks and the underlying technologies that make this concept possible.

Mobile satellite services are set to change with the imminent launch of satellite personal communication services (S-PCS), through the use of non-geostationary satellites. This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. One of the first texts to cover this rapidly evolving field, this text provides the reader with an overview of mobile satellite systems, from their initial introduction (Inmarsat), current satellite-PCS (referring to such systems as Globalstar), through to Satellite-UMTS and an understanding of the following: * The design concepts associated with non-geostationary satellite systems (constellation, link budgets, Doppler) * The concepts of UMTS (network architecture, aims, in the context of IMT-2000) and the role foreseen for the satellite component (complementary to terrestrial network, network extension, global availability) * Inter-working between satellite and terrestrial networks (network architecture, ATM Adaptation Layer) * Radio interface technologies (WB-CDMA, TDMA, transmission environment) * Regulatory issues * Future services and applications * Potential satellite markets (prediction techniques, effect of tariffing policies on potential market) With leading edge information, this valuable resource will be indispensable to researchers, engineers, operators and market evaluators in satellite service industries and research institutions, as well as postgraduates and research students in the field.

A Local Area Network (LAN) is a network usually within a single office or building that links desktop computers with each other and with peripherals such as servers and printers. The interconnect is the electrical and functional association of two different services, often provided by different suppliers, and it is from LAN inter-connection that telecoms operators seek to profit. The application of LAN interconnection via satellite can be used to complement and extend existing terrestrial public access networks through interconnection of clusters of broadband islands (such as LANs and MANs) in remote regions, where terrestrial lines are expensive to install and operate. Examples include:* Hospitals/clinics in remote and rural areas can be connected to the central hospitals in a tele-medicine environment* Remote offices can be connected to the central office to facilitate tele-working* University/colleges can be inter-connected to provide tele-education facilitiesSimilarly, the possibility to provide access to such facilities in developing regions of the world is also viable and particularly attractive in the short to mid-term. Private LAN connection facilities could also be made available to the corporate user, offering the possibility to establish broadband internet access within a closed user group. Such a scenario could be of interest to the financial sector. By gathering the knowledge and experiences of well-known satellite systems experts from different parts of Europe this comprehensive volume provides detailed analysis on technical aspects for interconnecting local area network using satellite. Starting from traffic source modelling for different types of applications and services to different types of transmission techniques and networking functions for supporting such services, different case studies are presented to analyse the performance of such technologies.By providing an insight to current and future developments in satellite communications systems and by covering a broad range of materials in technical aspects in relation to satellite communication systems technologies, this volume will be of tremendous use to researchers, academia and industry.* First book to present such a thorough description of the reliability functions of satellite systems* Discusses IP over satellite* Provides a unique analysis and description of different simulation tools that are under development for evaluating the performance of satellite systems* Includes a chapter devoted to traffic modelling for satellite systems* Reviews current research and developments in security and discusses how such security functions can be implemented over satellite networks* Addresses different types of routing strategies and includes three different case studies which have been carried out to analyse the performance of different routing strategies
