  • IP Mobility This chapter will provide an overview of IP mobility. It aims to be pretty selfcontained, and so should stand alone fairly independently of the other chapters. IP mobility is very important, because it is predicted that the vast majority of terminals will be mobile in a few years and that the vast majority of traffic will originate from IP-based applications. The challenge of ‘IP mobility’ is to deliver IP-based applications to mobile terminals/users, even though, traditionally, IP-protocols have been designed with the assumption that they are stationary...

  • The growth of the Internet, which I have been involved in, and the growth of mobile telephone services, which NTT DoCoMo has been a leader in, have been peculiarly interlinked and at the same time separate. The Internet is a lab experiment that broke free, and finds itself in a world of its own contriving, which it often does not understand. The mobile telephone world was developed for commercial purposes, and is in many respects the son of its father, the wired telephone system.

  • An Introduction to 3G Networks Introduction What exactly are 3G networks? 3G is short for Third Generation (Mobile System). Here is a quick run-down: † 1G, or first generation systems, were analogue and offered only a voice service – each country used a different system, in the UK TACS (Total Access Communications System) was introduced in 1980. 1G systems were not spectrally efficient, were very insecure against eavesdroppers, and offered no roaming possibilities (no use on holidays abroad.)....

  • Scope of the Book For some years, commentators have been predicting the ‘convergence’ of the Internet and mobile industries. But what does convergence mean? Is it just about mobile phones providing Internet access? Will the coming together of two huge industries actually be much more about collision than convergence? In truth, there are lots of possibilities about what convergence might mean, such as: † † † † Internet providers also supply mobile phones – or vice versa, of course.

  • IP for 3G In this final chapter, it is appropriate to revisit the theme that started the book. Chapter 1 outlined some of the reasons why IP should be introduced into 3G networks; this chapter will explain in greater detail the technicalities of how IP could be introduced. One result will be that a network is developed that is much more faithful to the original ‘Martini’ vision than current 3G incarnations.

  • An Introduction to IP Networks The Internet is believed by many to have initiated a revolution that will be as far reaching as the industrial revolution of the 18th and 19th centuries. However, as the collapse of many ‘dot.com’ companies has proven, it is not easy to predict what impact the Internet will have on the future. In part, these problems can be seen to be those normally associated with such a major revolution.

  • Quality of Service What is QoS? The basic definition of QoS is given by the ITU-T in recommendation E.800 as ‘‘the collective effect of service’’ performance, which determines the degree of satisfaction of a user of a service. There are a large number of issues, which affect user satisfaction with any network service. These include: † How much does it cost? † Can a user run the application they want? † Can a user contact any other user they want? None of these is a straightforward technical question....

  • The growth in the use of mobile networks has come mainly with the third generation systems and voice traffic. With the current third generation and the arrival of the 4G, the number of mobile users in the world will exceed the number of landlines users. Audio and video streaming have had a significant increase, parallel to the requirements of bandwidth and quality of service demanded by those applications. Mobile networks require that the applications and protocols that have worked successfully in fixed networks can be used with the same level of quality in mobile scenarios....
