This book addresses the needs of engineers and technicians who need to understand the most important new features and enhancements of the 3GPP-Releases 5, 6 and 7 and the ideas of 3GPP with respect to the long term evolution (LTE). In that respect, the book contains tabular overview sections that outline which network parts are affected by a change and whether the changes are mandatory or optional. In the next part, the training course provides a short overview of every feature and describes its operation and important characteristics. The book delves into more detail on some selected Release 5, 6 and 7-features. For Release 5, we explain in sufficient detail the IMS and HSDPA operation. For Release 6, a detailed introduction into HSUPA, MBMS and the adoption of alternative RAT’s like WLAN or WIMAX as I-WLAN or GAN (formerly UMAN) is included. This part includes a detailed description of the operation of important authentication and tunnel setup procedures EAP-SIM, EAP-AKA and IKEv2. For Release 7, we describe the important enhancements in the IMS area plus we provide a description of how MIMO operates in general and how it shall be used within 3GPP-networks. In addition, we illustrate the operation downlink dual carrier operation for GERAN. The book concludes with a description of the long term evolution (LTE) concepts and ideas of 3GPP and an introduction to OFDM which will be used in 3GPP-networks.weiterlesen
