We have telephony to talk to each other, messaging to dispatch mail or instant messages, browsing to read published content and search engines to locate content sites. However, current mobile networks do not provide the possibility for one application rich terminal to communicate with another in a peer-to-peer session beyond voice calls. Mobile telephony with the current technology has been hugely successful and shows that there is immense value in communicating with peers while being mobile, and with increasingly available smarter multimedia terminals the communication experience will be something more than just exchanging voice. Those multimedia terminals need IP multimedia networks. Hence, the Third Generation Partnership Project (3GPP) has developed a standard for SIP based IP multimedia service machinery known as 'The IMS (IP Multimedia Subsystem)' and this informative book explains everything you need to know about it∦∦... Presents the architecture and functionality of logical elements of IMS and their interfaces providing detailed description of how elements are connected, what protocols are used and how they are used Explains how the optimisation and security of the mobile communication environment has been designed in the form of user authentication and authorisation based on mobile identities Illustrates how optimisation at the radio interface is achieved using specific rules at the user to network interface. This includes signalling compression mechanisms as well as security and policy control mechanisms, allowing radio loss and recovery detection Addresses important aspects from an operator's point of view while developing architecture such as charging framework, policy and service control Describes many services on top of IMS in detail, including voice, presence, messaging and conferencing. Written in a manner that allows readers to choose the level of knowledge and understanding they need to gain about the IMS, this volume will have instant appeal to a wide audience ranging from marketing managers, research and development engineers, network engineers, developers, test engineers to university students.

SMS (short message service) and MMS (multimedia message service) are two of the hottest services in wireless communications today, offering customers exciting ways to communicate by sending text and multimedia messages. This comprehensive book offers wireless engineers and managers practical guidance in the planning and implementation of SMS and MMS services with interworking (the ability to successfully send a message when the origin and destination cellular phones do not use the same wireless operator). The book offers professionals various solutions to the common problem of number portability (a situation when a cellular phone has been "portedout" to another operator while keeping the same number) and provides methods for blocking spam from inbound SMS. Including numerous solved examples, this authoritative reference helps practitioners master of the key concepts they need to understand for their work in the field.

Communication is a fundamental and integral part of computing, whether between different computers on a network, or between components within a single computer. In this book Robin Milner introduces a new way of modelling communication that reflects its position. He treats computers and their programs as themselves built from communicating parts, rather than adding communication as an extra level of activity. Everything is introduced by means of examples, such as mobile phones, job schedualers, vending machines, data structures, and the objects of object-oriented programming. But the aim of the book is to develop a theory, the pi-calculus, in which these things can be treated rigorously. The pi-calculus differs from other models of communicating behaviour mainly in its treatment of mobility. The movement of a piece of data inside a computer program is treated exactly the same as the transfer of a message--or indeed an entire computer program--across the internet. One can also describe networks which reconfigure themselves. The calculus is very simple but powerful; its most prominent ingredient is the notion of a name. Its theory has two important ingredients: the concept of behavioural (or observational) equivalence, and the use of a new theory of types to classify patterns of interactive behaviour. The internet, and its communication protocols, fall within the scope of the theory just as much as computer programs, data structures, algorithms and programming languages. This book is the first textbook on the subject; it has been long-awaited by professionals and will be welcome by them, and their students.

The Mobile Revolution tells the story of the making of mobile markets and services worldwide, exploring the mobilization that is transforming how we live, work and play. The first comprehensive account of the explosion of mobile services (rich voice, internet, messaging, content), from multimedia messaging and camera phones to location-based services and mobile phone television, it tells the fascinating story of these products and services in the pioneering markets of Europe, the United States and the Asia-Pacific, particularly Japan, China and South Korea. This book is essential reading for managers and marketers who must now mobilize their products, servi ces and companies. It looks in depth at the impact of mobility in consumer and business markets, strategy, and across all industries and shows how marketing innovation has been brought about by developments in mobile technologies.

Rapid Mobile Enterprise Development for Symbian OS : An Introduction to OPL Application Design and Programming

A guide to programming Symbian OS smartphones using OPL (The Open Programming Language): a simple to learn, open-source scripting language, ideal for fast-track development of enterprise applications. This book provides a hands-on development environment for both the experienced and aspiring programmer, demonstrating the ease of use of Symbian OS technologies through the utilization of OPL. OPL has a shallow learning curve which allows bespoke corporate tools to be developed in house by technical staff who arenв€™t necessarily trained programmers. Rapid Mobile Enterprise Development For Symbian OS provides a clear guide on both how to program, and understanding the structure of the language through a keyword dictionary. Any bespoke OPL application can grow with a company, eventually providing access to more advanced C++ code through OPX extensions. From the home programmer who wants to do more with their phone, to the enterprise developer, Rapid Mobile Enterprise Development For Symbian OS is the ideal starting point for simple, innovative application design using OPL.
