This innovative new book explains how GPRS (general packet radio service) allows you to expand your GSM networks towards third generation mobile communications to meet the demands of the most-sophisticated mobile data applications. The book concentrates on the interfaces between the known GSM network elements and the new subsystems -- PCU, SGSN, and GGSN -- that come with GPRS. It offers you an in-depth explanation of the extensions and methods of the GSM air interface necessary for GPRS and shows how the channel-oriented GSM is linked to the packet switched GPRS. Moreover, it explains what extensions there are in channel coding, how resources are allocated on the air interface, and how the quick network access necessary for GPRS is made possible.

The book focuses on the specifics and procedures of the air-interface, while giving you a thorough understanding of IP related protocols and a detailed presentation of all the important protocol scenarios that you may encounter in GPRS and HSCSD. Other discussions include an introduction to GSM and TDMA, data transmission protocols, and terrestrial interfaces. An extensive glossary provides answers to many of the technical questions that may arise while utilizing GPRS, HSCSD, EDGE or IS-136 HS technology. Packed with more than 200 illustrations that support key topics.
