Wireless and Mobile Network Architectures (Wiley computer publishing) [Paperback]

An aspect that weighs in favor of the book is the inclusion of research results from the research of its two world renowned authors. The included research results can help the graduate level reader appreciate the available research opportunities, and the context in which solutions can be developed. The researcher will also find the collection of references (as recent as 2000) extremely helpful in studying the area. The teacher can use the material to develop simulation and analytical models for students to gain better insight to the workings of mobile services.

Another objective of the book, is to function as reference material. Its authors have done the hard work of distilling the essence of a large collection of standards documents related to mobility management. >From this point of view, the book will be of value in the longer term as well, making it an a perfectly sound investment.

A challenge dealt with successfully in this book is that in order to present mobility management, it ultimately needs to discuss about signaling protocols, and SS7 in particular. The book takes an approach of presenting background material on signaling on "as needed" basis. A reader not familiar with signaling, will likely progress slowly when signalling is first introduced, but, at the end, will have the double benefit of being exposed to signaling's central role in advanced communication services, and gain understanding on how mobile networks really work. Certainly, there are parts of the text where the density of acronyms calls for careful parsing of the sentences, but such is the case for any technical book that maintains a formal presentation style. It still beats reading standards documents.

After a short review and classification of the systems covered in the text, the book introduces the need and nature of mobility management followed by the most important aspect of mobility management, that of handoff management (detection, assignment and radio link transfer). Following the introduction, extensive attention is given to IS-41 (where, in a way, AMPS, IS-136 and IS-95 "meet" together) and to the GSM counterpart, the Mobile Application Part (MAP). Covered GSM services include the Short Message Service (SMS), International Roaming, and Operations, Administration and Maintenance. In this, first part of the book, what may appear odd at first is the inclusion of low-tier systems with few mobility management capabilities (such as CT 2, DECT etc.) but it serves as a reminder that little gems of protocols can be found in places one may not think looking at. Certainly the point is justified by the discussion of PACS signalling in a separate chapter. Another topic placed in this first part of the book (due to its relation with AMPS and IS-136) is CDPD's architecture and its radio resource allocation and roaming management.

The remaining half of the book is service-oriented. It covers how different types of services can be supported. The services include mobile number portability, VoIP service for mobile networks, GPRS, prepaid mobile phone services, and WAP. Following are two chapters covering the topic of heterogeneous PCS systems integration and the new (3rd) generation mobile services. The final three chapters cover three addition services that follow their own evolution path. Namely, paging systems, the wireless local loop and wireless enterprise networks.

Overall, this book is worth having. Whether you approach it as a student, as an instructor, as an engineer or just as interested to expand your knowledge, it has something to give you. It is unique in its approach and future books on the topic will be measured against it.
