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.Über den Autor:

Lee has worked with SS7/C7 throughout his entire career, approaching the subject from a number of perspectives, including software engineering, testing, training, security auditing, and architectural design, in both fixed-line and cellular networks, including 3G. Currently, Lee provides SS7/C7 training and consulting through his company, Bit Tech Limited. Lee is a member of several professional telecommunications bodies and holds a degree in computer science. He is currently studying for an engineering doctorate at the University College of London, focusing on SS7oIP issues. Jeff Hewett is a technical leader at Cisco Systems and is currently working in voice over IP software development. Having been involved with SS7 for more than 16 years, Jeff has worked in SS7 software development, testing, and training. He is a patent holder in SS7-related software development and has written about SS7 in popular journals. He has provided a broad range of SS7 training for Regional Bell Operating Companies, independent operators, and telecommunications vendors, dating back to the initial rollout of SS7 in the U.S. network. In more recent years, Jeff has been involved with voice over packet solutions as an engineer in the Cisco Networked Solutions Integration Test Engineering (NSITE) lab.
