A complete, practical guide to the world's most popular signaling system, including SIGTRAN, GSM-MAP, and Intelligent Networks. Provides in-depth coverage of the SS7 protocols, including implementation details Covers SS7 over IP (SIGTRAN) using real-world examples Covers SS7/C7 from both a North American and European perspective, providing a broad international understanding of the technology and associated standards Explains mobile wireless concepts and signaling, including mobile application part (MAP) Provides a thorough explanation of the Intelligent Network (IN) and associated protocols (INAP/AIN) Signaling System No. 7 (SS7) is a signaling network and protocol that is used globally to bring telecommunications networks, both fixed-line and cellular, to life. SS7 has numerous applications and is at the very heart of telecommunications. Setting up phone calls, providing cellular roaming and messaging, and supplying converged voice and data services are only a few of the ways that SS7 is used in the communications network. SS7 also provides the point of interconnection between converging voice and data networks. This transition, which affects everyone who works with the data network, has bolstered the need for practical and applied information on SS7. In short, anyone who is interested in telecommunications should have a solid understanding of SS7. Signaling System No. 7 (SS7/C7): Protocol, Architecture, and Services will help you understand SS7 from several perspectives. It examines the framework and architecture of SS7, as well as how it is used to provide today's telecommunications services. It also examines each level of the SS7 protocol-all the way down to the bit level of messages. In addition, the SIGTRAN standards are discussed in detail, showing the migration from SS7 to IP and explaining how SS7 information is transported over IP.

In this book we summarize important developments in telecommunications with a focus on Signalling System No. 7 (SS 7) network reliability. But why is SS 7 network security and reliability so important? According to the Open Systems Interconnection (OSI) model the term “network” refers to the Layer 3 network service, which is offered by the Message Transfer Part (MTP) and Signalling Connection Control Part (SCCP) to higher layers. An SS 7 network outage results in a breakdown of signalling between the individual nodes of the network, so that telecommunication network services are no longer available to customers. Apart from the tremendous nancial damage to the network operator, the social consequences of such a network breakdown cannot be underestimated. Since the MTP is the central part of the SS 7 network, it is of crucial importance for network security and reliability. The MTP is published in different versions and should now be what we call “stable”. Is it really stable? Does it work properly in real networks? Does it t new requirements so that no further changes within the MTP are needed? Various different implementations have existed for a long time and are used in national as well as the international network. Due to this, an objective is not to p- form any further changes within the MTP in order to avoid compatibility problems with existing and running systems. Experience shows that compatibility problems are always related to further development of the MTP.

The rapid growth of telecommunication in recent years has necessitated the creation of increasingly powerful and complex signaling systems and procedures. Once limited to setting up and releasing "plain old telephone service" calls, signaling functions now also support a variety of new telecommunication services. To operate effectively in this dynamic industry requires a solid grasp of the different systems and how they work. This book provides accessible, balanced coverage of subscriber signaling, interexchange signaling, signaling between mobile stations and a mobile network, and signaling between exchanges and other network entities. First, it provides a general introduction to telecommunication networks, with a hardware-oriented look at trunks, exchanges, and other basic components. It then introduces signaling concepts gradually, beginning with the older Channel-Associated Signaling (CAS) systems and progressing through today's Common-Channel Signaling (CCS) systems. Specific systems discussed include R2, CCITT No. 5, CCITT No. 6 and its North American counterpart, Common-Channel Interoffice Signaling (CCIS). Signaling System No. 7 (SS7) is treated in detail through a separate examination of its constituent elements-including its message transfer, telephone user, and ISDN user parts. Readers will also find information on U.S. and international requirements, signaling for transactions, and many other important topics.Complete with acronym glossaries and extensive references, Signaling in Telecommunication Networks serves as an excellent introductory text for students as well as a valuable reference for telecommunication engineers and technical managers.
