TL;DR: In this paper, the authors provide a detailed description and analysis of the global second generation (2G) mobile radio systems: the Global System of Mobile Communications (GSM) and cdmaOne.
Abstract: From the Book:
...Providing a detailed description and analysis of the global second generation (2G) mobile radio systems: the Global System of Mobile Communications (GSM) and cdmaOne, this volume examines how these two systems will evolve into the third generation (3G) with their requirement to support multimedia mobile radio communications.
The principle objectives of this book are to present to the reader detailed descriptions of the basic GSM and cdmaOne systems, mainly from the radio interface point of view; as well as accompanying analyses.
GSM was deployed before cdmaOne and is the market leader, entrenched in many parts of the world. Its success is due to numerous factors: its advanced backbone network, the introduction of subscriber identity modules (SIMs) that decoupled handsets from subscribers, its good security system, the low cost equipment due to open (i.e. public) interfaces, the relentless programme of evolution that has yielded substantial gains in spectral efficiency compared with the basic GSM system, and so on.
cdmaOne started as a radio interface. It was a bold step to use CDMA at a time when few thought CDMA could work in a cellular environment. But it did so, acquiring the necessary backbone network, and became a global standard offering tough competition to GSM. It is also worthy of note that Europe, which had designed and promoted GSM, has opted for wideband CDMA for its third generation (3G) networks.
The first chapter is designed to provide background material on TDMA, CDMA and cellular radio networks. Chapter 2 describes the basic GSM system and Chapter 3 provides an analysis of the performance of GSM networks. The same method of system description followed by a chapter dedicated to mathematical analysis is applied for cdmaOne in Chapters 4 and 5, respectively. The final chapter endeavours to describe how GSM is evolving to provide higher bit rate circuit-switched channels and packet transmissions that will have an ability to provide a range of multimedia services. The Universal Mobile Telecommunications System (UMTS) is then described, followed by a discussion of the evolution of cdmaOne to cdma2000. Both UMTS and cdma2000 are 3G systems....

TL;DR: This article describes the interactions between a PCN and the PSTN in four aspects: interconnection interfaces; message routing; mobility management; and call control.
Abstract: Personal communication services (PCS) facilitates the exchange of information (voice, data, video, image, etc.) for mobile users independent of time, location, and access arrangement. To support PCS, mobile communications protocols such as EIA/TIA Interim Standard 41 (IS-41) or Global System for Mobile Communications (GSM) have been defined for PCS network (PCN) inter-system operations. To support interconnection between a PCN and the public switched telephone network (PSTN), it is essential that the mobile communications protocol interacts with the PSTN signaling system for mobility management and call control. This article describes the interactions between a PCN and the PSTN in four aspects: interconnection interfaces; message routing; mobility management; and call control. To address these four aspects, we consider IS-41 as the mobile communications protocol and Signaling System No. 7 (SS7) as the PSTN signaling protocol. The IS-41 protocol is based on EIA/TIA IS-41 Revision B. We also describe some potential extensions of the IS-41 protocol based on a draft of IS-41 Revision C. >

TL;DR: The cdma2000 radio transmission technology (RTT) is based on the evolution of the current cdmaOne∗ system to a multimedia system that offers additional capacity and service enhancements, providing a smooth migration path from second- to third-generation systems.
Abstract: The requirements of a third-generation radio transmission system include support for multimedia services, global roaming, operation in multiple environments both fixed and mobile, and high-speed data services. The cdma2000 radio transmission technology (RTT) is based on the evolution of the current cdmaOne∗ system to a multimedia system that offers additional capacity and service enhancements. While meeting the requirements of a third-generation wireless system, the cdma2000 RTT maintains backward compatibility with currently deployed cdmaOne networks worldwide, providing a smooth migration path from second- to third-generation systems.

TL;DR: This guide fully explains and annotates the IS-41 protocol, and graphically illustrates common signaling situations that expedite network implementation, with numerous specific examples of how the protocol is used and coverage ofIS-41-C—the latest revision of the standard.
Abstract: From the Publisher:
IS-41 is the North American standard for wireless telecommunications network signaling. This guide fully explains and annotates the IS-41 protocol,and graphically illustrates common signaling situations. Sections on all major IS-41 revisions feature coverage of the standard's support for analog and digital interfaces. Network implementation is simplified by extensive details on components,parameters,and procedures.
Rely on the only guide dedicated entirely to the IS-41 protocol! MOBILE TELECOMMUNICATIONS NETWORKING WITH IS-41 IS-41the North American standard for wireless telecommunications network signalingremains perplexing to engineers and technical managers because of its complexity. Now two contributors to the IS-41 standard explain the latest revisions,operational details,and protocol usage of the standard in easy-to-understand terms. They fully annotate the protocol usage of the standard in easy-to-understand key components,including its messages,parameters,and procedures. Discussion of how the IS-41 protocol provides mobile functions accompanies graphic illustrations of common network signaling situations that expedite network implementation. You'll also gain a complete grasp of how IS-41 relates to other functions in the network.

TL;DR: The author describes the Jambala Mobility Gateway, a new application from Ericsson that provides the level of convergence necessary to interface GSM and TDMA/AMPS networks.
Abstract: As business becomes truly global and international, the need to communicate anytime, anywhere becomes more crucial. The demand for international roaming has grown spectacularly and is expected to continue growing into the new millennium. With the tremendous installed base of GSM and TDMA/AMPS wireless networks in the world, international roaming has evolved to require intersystem roaming capability; that is, roaming between GSM and TDMA/AMPS networks. In addition, operators seeking to enter established wireless markets are increasingly requiring the use of inter-system roaming to enable them to use the cellular coverage offered by partners in the same or neighboring areas. The author describes the Jambala Mobility Gateway, a new application from Ericsson that provides the level of convergence necessary to interface GSM and TDMA/AMPS networks. conform to TDMA/AMPS (IS-41, revisions B and C, and ANSI-41, revision D) and GSM standards (MAP versions 1 and 2). Furthermore, the Mobility Gateway does not impose any modifications on individual network components, such as HLRs and MSC/VLRs in current GSM and TDMA/AMPS environments. The mapping of MAP and ANSI-41 protocols allows for the exchange of information needed to provide basic mobility management across different networks, thus permitting users to roam from one network to another. Consequently, the protocols and interfaces associated with service delivery in
