Based on the latest updates on the 3GPP specifications, this book investigates the differences of a GSM/GPRS network compared to a Universal Mobile Telecommunications System (UMTS) network, the technical aspects that ensure their interoperability, and detailed descriptions of the elements in the UMTS network architecture, including User Equipment (UE), the UMTS Radio Access Network (UTRAN), and the core network. Completely new protocols based on the needs of the new Wideband Code Division Multiple Access (WCDMA) air interface are highlighted by considering both Frequency and Time-Division Duplex modes and key features of existing topics in Releases 5, 6, and 7, such as High Speed Downlink Packet Access (HSDPA), IP Multimedia Subsystem (IMS), WLAN interconnection, and Multicast/Broadcast Multimedia Subsystem (MBMS)
