Date :2008-12-01. 2G GSM and 3G UMTS mobile communications technology is important. the current GSM and UMTS in the world has more than 200 million users. In order to meet the service bandwidth. service quality and network coverage. and many other needs. 3G standards has launched a new evolution of technology. Evolved Packet System (Evolved Packet System. EPS) is a 3GPP Standards Committee developed the latest evolution of the 3G UMTS standard. including long-term evolution of wireless interfaces (Long Term Evolution. LTE) and System Architecture Evolution (System Architecture Evolution. SAE). This book systematically studied the evolution of UMTS - EPS. according to from the wireless interface - the core network - the order of business structure gradually describes the various components of EPS. and key technologies. In each section. given the EPS and the 2G GSM and 3G UMTS inheritance. and focuses on the different EPS with existing systems and the improvements made. Book describes and summarizes the 3GPP standards body s hundreds of documents. in addition to a number of technical standards for the proposed new point of view. so that readers can comprehensive and thorough understanding of EPS. This book by the French Alcatel-Lucent two different fields (ie radio interface and network architecture) and written by experts. the book contains many illustrations and examples. so readers can better understand the book s contents. Book both for wireless communications researchers and engineers. but also as institutions of higher education teachers. graduate students and senior undergraduate textbooks or reference books.
