Description: After the successful global introduction during the past decade of the second generation (2G) digital
mobile communications systems, it seems that the third generation (3G) Universal Mobile Communication
System (UMTS) has finally taken off, at least in some regions. The plethora of new services that
are expected to be offered by this system requires the development of new paradigms in the way scarce
radio resources should be managed. The Quality of Service (QoS) concept, which introduces in a natural
way the service differentiation and the possibility of adapting the resource consumption to the specific
service requirements, will open the door for the provision of advanced wireless services to the mass
market.

Description: 通信技术发展要求蜂窝运营商必须能够支持新的3G技术，在一个充满竞争的市场机制下以合理的价格提供基于多媒体业务的无线Internet能力，本书以此为蓝图主要从3部分进行阐述：
·集中阐述了GSM系统如何完全无缝演化为支持UMTS业务的GERAN。部分内容还包括演化过程中涉及的功能、结构组成、系统统一以及3G网络提出的各种UMTS QoS要求等。
·从仿真和实际系统测试的角度阐述各种先进技术的性能。本部分全面讨论了GSM、GPRS、EDGE、AMR和支持3G业务的GERAN等系统工技术的特征和性能。同时也介绍了无线接入网络的自动规划、优化和运营方法和技术。阐述了跳频技术的自动规划和无线资源管理各参数的优化等，另外对系统出现故障或者崩溃的各种原因进行了分析。
·讨论了各种不同的3G无线技术，同时说明了GERAN在这些技术中所处的地位。分析了各种演化策略，描绘了3G多无线接入网络的场景，阐述了内在的GSM和WCDMA系统无缝融合技术。 -Communication technology requirements of the development of cellular operators must be able to support the new 3G technology, in a competitive market mechanism to provide a reasonable price of wireless multimedia services based on Internet capabilities, this book as a blueprint for the major part of from 3:
Focused on how the system completely seamless GSM Evolution UMTS business to support GERAN. Part of the contents of the course also includes the evolution of function, structure, systems, and unification of the various 3G networks UMTS QoS requirements.
Simulation and from the perspective of the actual system testing on the performance of various advanced technologies. A comprehensive discussion of this part of the GSM, GPRS, EDGE, AMR and support for 3G systems such as GERAN business techniques and performance characteristics. At the same time, also introduced an automatic wireless access network planning, optimization and operation of methods and techniques. On the automatic fre

Description: a paper about UMTS, In this paper authors present a man-in-the-middle attack on the
Universal Mobile Telecommunication Standard (UMTS),
one of the newly emerging 3G mobile technologies. The attack
allows an intruder to impersonate a valid GSM base station
to a UMTS subscriber regardless of the fact that UMTS
authentication and key agreement are used. As a result, an
intruder can eavesdrop on all mobile-station-initiated traffic

Description: Technological and security enhancements in third generation (3G) architecture led to the development of the fourth
generation (4G) technology. 4G is developed and standardized by the 3GPP which is a fully IP based topology and also referred
to as the future communication technology. 3GPP provided LTE (Long Term Evolution) usually referred to as the standard for
fourth generation telecommunications. This paper reviews the core architecture of the 4G network and also reviews the
Authentication and key agreement (AKA) protocol as the access mechanism to a 4G network which shows the strong security
aspects of the fourth generation technology.
