Download or read book Softswitch written by Frank Ohrtman and published by Mcgraw-hill. This book was released on 2003 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bypassing the old circuit-switched hardware, softswitches streamline message traffic and provide a much more efficient service development environment. Along with SIP, this technology leverages Internet technologies to replace plain-old-telephone service. Developers who are freed up by softswitch technology to build cost-effective 3G serives will learn how it works and what applications it can support. Network managers making hard decisions about whether to deploy VoIP will learn pros and cons, costs and benefits, and most importantly how to separate myth from reality.

Download or read book Wireless Communications Systems and Networks written by Mohsen Guizani and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1990s, the wireless communications field has witnessed explosive growth. The wide range of applications and existing new technologies nowadays stimulated this enormous growth and encouraged wireless applications. The new wireless networks will support heterogeneous traffic, consisting of voice, video, and data (multimedia). This necessitated looking at new wireless generation technologies and enhance its capabilities. This includes new standards, new levels of Quality of Service (QoS), new sets of protocols and architectures, noise reduction, power control, performance enhancement, link and mobility management, nomadic and wireless networks security, and ad-hoc architectures. Many of these topics are covered in this textbook. The aim of this book is research and development in the area of broadband wireless communications and sensor networks. It is intended for researchers that need to learn more and do research on these topics. But, it is assumed that the reader has some background about wireless communications and networking. In addition to background in each of the chapters, an in-depth analysis is presented to help our readers gain more R&D insights in any of these areas. The book is comprised of 22 chapters, written by a group of well-known experts in their respective fields. Many of them have great industrial experience mixed with proper academic background.

Download or read book Service Provision written by Kenneth J. Turner and published by John Wiley & Sons. This book was released on 2005-01-28 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first overview of the service technologies available to telecoms operators working in a post-convergence world. Previous books have focused either on computer networks or on telecoms networks. This is the first to bring the two together and provide a single reference source for information that is currently only to be found in disparate journals, tool specifications and standards documents. In order to provide such broad coverage of the topic in a structured and logical fashion, the book is divided into 3 parts. The first part looks at the underlying network support for services and aims to explain the technology that makes the user-visible services possible. This section covers multimedia networking, both traditional (legacy) and future (softswitch) call processing, intelligent networks, the Internet, and Wireless networks. Part 2 deals with how these services may be analysed and managed. Chapters cover topics such as commercial issues, service management, quality of service, security, standards and APIs. Part 3 concludes the book by looking ahead at evolving technologies and more speculative possibilities, discussing the kinds of services that may be possible in the future and the technologies that will support them. * Focuses is on how the technology supports the services, rather than on technology for its own sake * Contributors drawn from both academia and industry (companies such as Marconi, BT, Telcordia, Cisco, Analysys) to give both theoretical and real-world perspectives * Unique singe-reference source for a wide range of material currently found only in disparate papers, specs and documentation * Covers brand new technologies such as JAIN, JTAPI, Parlay, IP, multimedia networking, active networks, WAP, wireless LANs, agent-based services, etc.
Download or read book Mobile Computing written by Ajit Singh and published by Ajit Singh. This book was released on 2021-07-15 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid development of wireless digital communication technology has created capabilities that software systems are only beginning to exploit. The falling cost of both communication and mobile computing devices (laptop computers, hand-held computers, etc.) is making wireless computing affordable to both business users and private consumers. Mobile computing is not a `scaled-down' version of the established and well-studied field of distributed computing. The nature of wireless communication media and the mobility of computers combine to create fundamentally new problems in networking, operating systems, and information systems. Furthermore, many of the applications envisioned for mobile computing place novel demands on software systems. Mobile computing systems are computing systems that may be easily moved physically and whose computing capabilities may be used while they are being moved. Examples are laptops, personal digital assistants (PDAs), and mobile phones. By distinguishing mobile computing systems from other computing systems we can identify the distinctions in the tasks that they are designed to perform, the way that they are designed, and the way in which they are operated. There are many things that a mobile computing system can do that a stationary computing system cannot do; these added functionalities are the reason for separately characterizing mobile computing systems. This book will give the introduction and basic concepts of mobile communication. This book does not require any prior knowledge from the student, and is therefore suitable to study the basic concepts and advanced topics. This book on the subject mobile computing should aim to help a student in developing a good understanding of mobile communication systems. This book captures the present state of the field and serves as an invaluable source of reference material. This book guides communications professionals and students through the complex web of acronyms, standards that wireless data runs on.

Available in PDF, EPUB and Kindle. Book excerpt: SIP Trunking & Carrier Connections This module is all about connecting to carriers to communicate VoIP phone calls, both carrier-to-carrier connections and business-to-carrier SIP trunking. You'll learn how competitive carriers terminate VoIP phone calls on Local Exchange Carriers using the switched access tariff and tandem access trunks. We'll understand why this will be a native VoIP connection in the future, and the role of Session Border Controllers. Then we'll understand how a business system can connect its locations and to the PSTN using SIP Trunking services, and the advantage over the legacy ISDN PRI PBX trunks.
