Network Switching Subsystem
29,00 € *
ggf. zzgl. Versand

Network switching subsystem (NSS) is the component of a GSM system that carries out switching functions and manages the communications between mobile phones and the Public Switched Telephone Network (PSTN). It is owned and deployed by mobile phone operators and allows mobile phones to communicate with each other and telephones in the wider telecommunications network. The architecture closely resembles a telephone exchange, but there are additional functions which are needed because the phones are not fixed in one location. Each of these functions handle different aspects of mobility management and are described in more detail below.

Voice over IP Security
58,84 € *

Voice over IP (VoIP) and Internet Multimedia Subsystem technologies (IMS) are rapidly being adopted by consumers, enterprises, governments and militaries. These technologies offer higher flexibility and more features than traditional telephony (PSTN) infrastructures, as well as the potential for lower cost through equipment consolidation and, for the consumer market, new business models. However, VoIP systems also represent a higher complexity in terms of architecture, protocols and implementation, with a corresponding increase in the potential for misuse.In this book, the authors examine the current state of affairs on VoIP security through a survey of 221 known/disclosed security vulnerabilities in bug-tracking databases. We complement this with a comprehensive survey of the state of the art in VoIP security research that covers 245 papers. Juxtaposing our findings, we identify current areas of risk and deficiencies in research focus. This book should serve as a starting point for understanding the threats and risks in a rapidly evolving set of technologies that are seeing increasing deployment and use. An additional goal is to gain a better understanding of the security landscape with respect to VoIP toward directing future research in this and other similar emerging technologies.

NGN Architectures, Protocols and Services
161,00 CHF *
ggf. zzgl. Versand

Comprehensive coverage explaining the correlation and synergy between Next Generation Networks and the existing standardized technologies This book focuses on Next Generation Networks (NGN); in particular, on NGN architectures, protocols and services, including technologies, regulation and business aspects. NGN provides convergence between the traditional telecommunications and the Internet, and it is globally standardized by the ITU (International Telecommunication Union), where ITU is the United Nations specialized agency for Information and Communication Technologies - ICTs. The convergence towards the NGN is based on the Internet technologies, and the introductory chapters cover the Internet fundamentals of today, including architectures, protocols (IPv4, IPv6, TCP, DNS, etc.), Internet services (WWW, e-mail, BitTorrent, Skype, and more), as well as Internet governance. Further, the prerequisite for convergence of all ICT services over single network architectures is broadband access to the Internet. Hence, the book includes architectures of fixed broadband Internet access networks, such as DSL (Digital Subscriber Line) networks, cable networks, FTTH (Fiber To The Home), next generation passive and active optical networks, and metro Ethernet. It also covers network architectures for next generation (4G) mobile and wireless networks (LTE/LTE-Advanced, and Mobile WiMAX 2.0), then Fixed Mobile Convergence - FMC, next generation mobile services, as well as business and regulatory aspects for next generation mobile networks and services. * Comprehensive coverage explaining the correlation and synergy between Next Generation Networks and the existing standardized technologies * Focuses on Next Generation Networks (NGN) as defined by the ITU, including performance, service architectures and mechanisms, common IMS (IP Multimedia Subsystem), control and signalling protocols used in NGN, security approaches, identity management, NGN Service Overlay Networks, and NGN business models * Examines the most important NGN services, including QoS-enabled VoIP, IPTV over NGN, web services in NGN, peer-to-peer services, Ubiquitous Sensor Network (USN) services, VPN services in NGN, Internet of things and web of things * Includes the transition towards NGN from the PSTN (Public Switched Telephone Networks) and from the best-effort Internet via the same Internet access * Explores advanced topics such as IPv6-based NGN, network virtualization, and future packet based networks, as well as business challenges and opportunities for the NGN evolved networks and services Essential reading for engineers and employees from regulatory bodies, government organisations, telecommunication companies, ICT companies.

The 3G IP Multimedia Subsystem (IMS): Merging the Internet andthe Cellular Worlds, Second Edition is an updated version ofthe best-selling guide to this exciting technology that will mergethe Internet with the cellular world, ensuring the availability ofInternet technologies such as the web, email, instant messaging,presence and videoconferencing nearly everywhere. In thisthoroughly revised overview of the IMS and its technologies, goals,history, vision, the organizations involved in its standardizationand architecture, the authors first describe how each technologyworks on the Internet and then explain how the same technology isadapted to work in the IMS, enabling readers to take advantage ofany current and future Internet service. Key features of the Second Edition include: * New chapter on Next Generation Networks, including an overviewon standardization, the architecture, and PSTN/ISDN simulationservices. * Fully updated chapter on the Push-to-talk over Cellular (PoC)service, covering the standardization in the Open Mobile Alliance(OMA), architecture, PoC session types, user plane, and the TalkBurst Control Protocol. * Several expanded sections, including discussion of the role ofthe Open Mobile Alliance in the standardization process, IPv4support in IMS, a description of the IMS Application Layer Gatewayand the Transition Gateway, and a description of the presence datamodel. * Updated material on the presence service, session-based instantmessages with the Message Session Relay Protocol (MSRP), and theXML Configuration Access Protocol (XCAP). * Supported by a companion website on which instructors andlecturers can find electronic versions of the figures. Engineers, programmers, business managers, marketingrepresentatives, and technically aware users will all find this tobe an indispensable guide to IMS and the business model behindit.
