The UMTS Development Platform
Jonathan P. Castro · 2001
Chapter 3 describes the UMTS development platform. It introduces its architecture top down identifying the core and access network domains. It defines the UTRA identifiers and functions, e.g. system access control, radio channel ciphering and deciphering, mobility functions, and radio resource management and control functions. It presents also mobility management with its signaling connections and impacts of mobility handling. Chapter 3 presents the UTRAN synchronization and UTRAN interfaces besides pointing out 2G/3G network co-existing issues . It does also introduce the Radio Interface Protocol Architecture with its structure in terms of services and function layers. This chapter thus outlines the most relevant elements, which require technical description for design and implementation.
